11:50 Post combustion carbon capture with amine based deep eutectic solvents (DESs) Idowu Adeyemi (Masdar Institute & Masdar Institute, United Arab Emirates (UAE)); Mohammad Abu­Zahra and Enas Muen Nashef (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) This study seeks to determine the solubility of carbon dioxide in amine based deep eutectic solvents (DESs). The CO2 absorption  was  conducted  with  a  solvent  screening  set­up  (SSS)  and  the  CO2  loading  was  measured  with  a  total organic carbon (TOC) analyzer. The solubility experiments were performed based on the conditions of the absorber in the post­combustion capture process (PCO2 = 15kPa and T = 40oC). Results revealed that amine­based DESs have absorption capacity that is higher than aqueous amines. The solubility of CO2 was found to increase as the molar ratio of the amine in the DES increased.

12:10 Isolation and characterization of novel Tetraselmis striata strain AAH001 from Abu Dhabi's desert Ahmed Alharthi and Hector Hernandez (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Deserts are among the most extreme environments that microalgae species thrive in, helping maintain the ecological balance  of  such  ecosystems.  Microalgae  desert  strains  have  adapted  to  temperature  variability,  salinity,  nutrients scarcity, and solar radiation. These mechanisms are significant to Abu Dhabi's environment as microalgae can provide solutions to water, food, and energy security challenges. One such strain has been isolated from a small water pond in Al  Wathbah  desert  in  Abu  Dhabi.  This  novel  strain,  named  AAH001,  was  genetically  characterized  as  a  strain  of Tetraselmis striata by sequencing of its Internal Transcribed Spacer (ITS) regions. Strain AAH001 exhibits growth in salinities  ranging  from  5ppt  up  to  300ppt,  with  the  optimum  growth  at  75ppt.  This  strain  exhibited  salinity  specific growth optima and was shown to tolerate growth temperatures of up to 40 °C. Strain AAH001 was able to grow using air supplemented with up to 12% CO2 content.

12:30 Study of a novel cylindrical flow electrodes capacitive deionization process HsinTan HO (Masdar, United Arab Emirates (UAE)) A  cylindrical  flow­electrode  capacitive  deionization(FCDI)  module  with  continuous  circulating  of  flow­electrodes  was designed. The flow­electrodes used in this study consisted of activated carbon(AC) particles that were suspended in deionized  water.  It  was  found  that  the  FCDI  that  was  operated  with  both  flow­electrodes  streams  were  combined showed better salt­removal efficiencies than the both flow­electrodes streams were not combined. This was due to the charges  were  neutralized  in  the  combined  mode,  ions  were  desorbed  and  the  flow­electrodes  were  automatically regenerated when both steams were mixed. Hence, this design eliminated the energy intensive regeneration step of the conventional­CDI operational approach. The salt adsorption process by AC particles can be described by a physical adsorption  process,  which  are  affirmed  by  the  kinetic­model.  These  experimental  results  confirmed  the  feasibility  of using a novel cylindrical flow capacitive deionization module to remove salt ions from stream and paved the ways for scale up applications in water purification.

M­SB1: Energy & Fuels Room: 202006 (New Ext. ­ 2nd Floor) Chair: Wael Zaki (Khalifa University of Science Technology and Research, United Arab Emirates (UAE)) 11:30 Thermoeconomic Analysis of Densely­Packed Concentrated Photovoltaic Thermal (CPVT) Solar Collectors in Thermally in­Series and in­Parallel Receiver Configurations Omar Sharaf (Khalifa University, United Arab Emirates (UAE)) A concentrated photovoltaic thermal (CPVT) solar collector maximizes utilization of the solar input by simultaneously generating  electrical  and  thermal  outputs.  The  concept  of  a  CPVT  attempts  to  address  three  main  barriers  to  solar technologies; namely, low energy density, high cost, and low efficiencies. In the present study, two high­concentration densely­packed  CPVT  configurations  are  optically  and  thermodynamically  designed  and  evaluated,  incorporating exergoeconomic  and  environmental  assessments.  The  designs  are  composed  of  parabolic  dish  concentrators,  multi­

27

junction  photovoltaic  cells,  segmented  thermoelectric  generators  with  interconnectors,  and  finned  minichannel  heat extractors.  In  configuration  I,  the  receiver  assembly  components  are  connected  thermally  in­series  whereas  in configuration II they are connected thermally in­parallel. It is found that the thermally in­series configuration offers an average  annual  exergy  efficiency  of  29.12%  compared  to  19.28%  for  the  thermally  in­parallel  configuration.  Both configurations offer comparable average annual energy efficiencies with a slight environmental and exergoeconomic advantage to the thermally in­parallel configuration.

11:50 Kinetic Analysis of Catalytic Coal Gasification Shahid Rabbani (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Catalytic coal gasification process is a useful technology used in the plants that use coal, especially the ones that use SNG (Substitute Natural Gas) and IGFC (Integrated Gasification Fuel Cell). This process was developed back in 1978 but not much work has been done on computational thermodynamic analysis of catalytic coal gasification. The purpose of this study is to model the Catalytic coal gasification process in Aspen Plus and investigate the kinetic values of the process in presence of Potassium Carbonate as Catalyst. In order to reduce CO2 emission from the coal and increase the boiler efficiency using coal as fuel, we have also included analysis of drying characteristics of coal using Aspen Plus model  of  the  catalytic  converter  process.  After  modelling  and  validating  the  results  from  available  experimental results, exergy analysis of the whole process is also included in the project.

12:10 Valorisation of Biomass from Arid Regions­A case for Pyrolysis Prosper Dzidzienyo (MASDAR INSTITUTE, United Arab Emirates (UAE)) The  study  sampled  different  biomass  types  common  to  arid  regions  that  can  be  grown  with  saline  water  including halophytes  like  Salicornia  bigelovii,  cellulosic  agricultural  waste  like  date  palms  (Phoenix  dactylifera),  macroalgae Ulva  lactuca  and  a  microalgae  Arthrospira  platensis,  food  waste  and  composted  waste  sludge.  Slow  Pyrolysis  was performed on all biomass types and the distribution of pyro­oil, char and gases from these biomasses are presented. Pyro­oil yields varied from 0.4% to 37% for different biomasses from 300 °C to 550 °C. Salicornia bigelovii straw gave the  highest  yield  of  pyro­oil  at  34%  at  450°C.  The  calorific  values  of  the  original  biomasses,  the  pyro­oil  and  chars were also measured. Mass and energy balance analysis was used to compute the calorific values of the pyrolysis gases.

12:30 Maximization of output power of the final optical element in the CSPonD Demo prototype Miguel Diago, Peter Armstrong and Nicolas Calvet (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) The  CSPonD  Demo  prototype  consists  of  a  volumetric  molten  salt  solar  receiver  that  accepts  concentrated  solar radiation from a beam­down tower via a final optical element (FOE). This works researches the canting angles of the tower central reflectors that maximize the thermal output of the FOE. This value can vary over 20 % depending on the selection  of  the  canting  configuration.  For  a  given  FOE  construction,  the  best  canting  configuration  of  the  central reflectors depends on the reflectivity of the FOE facets. It is found that as the reflectivity decreases, the best canting are those which bring the aiming point of the central reflector lower on the axis of the FOE.

Room: 202021 (New Ext. ­ 2nd Floor) Chairs: Rehan Umer (Khalifa University, United Arab Emirates (UAE)), Sharmarke Mohamed (Khalifa University, United Arab Emirates (UAE)) 11:30 SiC Based Radiative Cooling Structure Afra Alketbi, Aikifa Raza, Jin You Lu and TieJun Zhang (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Radiative cooling has attracted a lot of attention in the past few years due to its diverse potential applications such as in  dry  cooling  of  domestic  building  or  even  solar  cells.  The  radiative  cooling  process  utilizes  the  existence  of  a transparency window in Earth's atmosphere between 8 to 13 μm. Over the past few years many designs have emerged that make use of this fact and has a selective emittance that helps dissipate the absorbed heat and lower the surface temperature.  In  this  work  we  introduce  a  novel  yet  simple  design  that  enables  the  cooling  process.  The  design  is composed of a single layer of Silicon Carbide (SiC) with a Distributed Bragg's Reflector (DBR) that utilizes nano­porous SiO2 films on top. FDTD simulation of the proposed structure demonstrated the two main qualities for radiative cooling, high reflection in the visible range and high ultra broadband emission within the transparency window.

11:50 Electrospun WO3­NiWO4 Composite Nano Fibers as Active Electrocatalysts for Hydrogen Evolution Reaction Shaheen Anis, Boor Lalia and Ahmad O. Mostafa (Masdar Institute of Science and Technology, United Arab Emirates (UAE)); Raed Hashaikeh (Masdar, United Arab Emirates (UAE)) Nickel  tungstate­  tungsten  oxide  composite  fibers  were  synthesized  through  the  electrospinning  method  using precursor salt solutions of nickel and tungsten. Composite fiber morphology and structure were studied using SEM and X­ray diffraction. The composite fibers were investigated for electrocatalytic hydrogen evolution reaction in both acidic and alkaline media where they showed good electrocatalytic activity with respect to over potentials and Tafel slopes. The study showed that the NiWO4 compound, formed during the composite fabrication, was responsible for improving the  electrocatalytic  performance  of  the  fibrous  catalyst.  Besides  electrocatalysis,  nickel­tungsten  oxide  fibers  have immense potential in applications ranging from photo catalysis to gas sensing.

Technology, United Arab Emirates (UAE)); Falah Hasoon (National Energy and Water Research Center (NEWRC), United Arab Emirates (UAE)) Photovoltaic  (PV)  technology  is  one  of  the  key  answers  for  a  better  sustainable  future.  An  important  layer  in  the structure  of  common  PV  cells  is  the  transparent  conductive  oxide  (TCO).  A  widely  applied  TCO  is  tin  oxide.  The advantage  of  using  tin  oxide  comes  from  its  high  stability,  and  it  is  inexpensive  in  terms  of  raw  materials  and processing techniques. We discuss our study of depositing thin­film tin oxide layer by utilizing magnetron RF­sputtering technique  while  varying  the  Ar  inert  gas  flow  rate  and  oxygen  content.  Preliminary  results  showed  that  sheet resistance  values  obtained  for  the  tin  oxide  films  spanned  across  four  orders  of  magnitude  in  their  as­deposited amorphous conditions, and transmittance values extending from 47 to 90% within the visible light spectrum.

12:30 The Effects of Ball Milling on Freestanding Sheets of MWCNT Electrodes for Vanadium Redox Flow Batteries Tawaddod Alkindi, Ibrahim H. S. Mustafa, Saif Almheiri and Zainab Karam (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Unique properties such as high porosity, large surface area, inducible wettability, high mechanical strength, and high chemical  activity  are  excellent  reasons  to  make  MWCNTs  an  interesting  area  of  research  as  Vanadium  Redox  Flow Batteries  (VRFBs)  electrodes  materials.  In  this  experimental  work,  freestanding  sheets  of  MWCNTs,  known  as buckypapers,  were  fabricated.  A  ball  milling  process  was  performed  as  a  pretreatment  to  fabricate  electrodes  for VRFBs. The effects of various ball milling speeds on the electrodes performance was studied; Surface area, amount of de­bundling,  and  amount  of  defects  increased  as  ball  milling  speeds  increased,  as  proven  by  SEM  Microscopy  and Raman  Spectroscopy.  Electrochemical  performance  improved  as  ball  milling  speeds  increased  as  evident  by Voltammetry.

11:50 Application of Rotating Nonlinear Energy Sinks to Large­Scale Structure Adnan Saeed (Khalifa University, United Arab Emirates (UAE)); Mohammad Alshudeifat (Khalifa Universiy, United Arab Emirates (UAE)) Over the last decade, Nonlinear Energy Sinks (NESs) have experienced a significant development and gained rapid­ growing interest. One of the recent new types of NESs is the rotating NESs which has further been enhanced recently to incorporate an elastic arm and therefore another degree of freedom is added. This article presents the numerical simulations of attaching two rotating elastic NESs to the top and second top floors of a real life nine­story structure.

12:10 Experimental and numerical study of heat transfer in a circular duct with vortex generators insert Guangda Liang (Petroleum Institute, United Arab Emirates (UAE)); Kharoua Nabil and Md Didarul Islam (The Petroleum Institute, United Arab Emirates (UAE)) Current study presents an experimental work on the thermal augmentation and pressure penalty in a constant heat­ fluxed  circular  duct  with  vortex  generators  insert.  The  experiment  was  conducted  in  turbulent  flow  regime  with  a Reynolds  number  ranging  from  6000  to  27000.  The  results  suggested  that  by  increasing  the  length  of  winglet,  both heat  transfer  coefficient  and  friction  factor  will  intensify.  With  lower  pitch  ratio,  higher  Nusselt  number  and  friction factor are achieved. The maximum heat transfer efficiency is obtained for the length of 20 mm, pitch ratio of 1.6 and Reynolds number of 27000. However, the highest thermal enhancement factor of 1.59 is obtained for the length of 10 mm, pitch ratio of 4.8 and Reynolds number of 6000. The flow structure was also precisely portrayed.

12:30 Variable­Refrigerant­Flow Cooling­Systems Performance at Different Operation­ Pressures and Types­of­Refrigerants Roba Saab (Masdar Institute for Science and Technology, United Arab Emirates (UAE)); Mohamed I Ali (Masdar, United Arab Emirates (UAE)) This paper presents energy models of the variable refrigerant flow (VRF) technology. VRF is an advanced type of air conditioning  systems  proposed  to  be  implemented  in  Masdar  Eco­Villas  in  Abu  Dhabi.  VRF  units  manufactured  by Daikin  and  LG  companies  were  both  modeled  and  compared  using  engineering  equation  solver  (EES)  software.  The models done on EES were repeated for validation on IPSEpro software, and the results were similar within 4% error. Finally, different refrigerants were modeled and the results showed that refrigerant R­410a would be the second most efficient refrigerant for such systems. The model results have been validated with the Daikin system installed in Dubai.

11:50 A Study of the Interface Quality of Ge­Based MOS Capacitors using RF Plasma Nitration Ghada Dushaaq (UAE, Abu Dhabi & Masdar Institute of Science & Technology, United Arab Emirates (UAE)); Mahmoud Rasras (Masdar Institute of Technology, United Arab Emirates (UAE)); Ammar Nayfeh (Masdar Institute of Science & Technology, United Arab Emirates (UAE)) in this paper, nitration of germanium surface using a mixture of N2O, NH3 and N2 is performed using RF­PECVD reactor. The  electrical  characteristics  of  Al/HfO2/GeON/p­Ge  capacitors  are  investigated.  Results  show  that  the  hysteresis  of metal­oxide­semiconductor (MOS) capacitors with nitration­based passivation step is reduced to ~150 mV, compared with ~400mV of the untreated sample. The suppression of hysteresis is attributed to the reduction of electron traps and  enhancement  of  dielectric/Ge  interface  quality.  The  improved  interface  quality  of  plasma­based  nitration  of  Ge surface is a promising technique for high performance Ge MOSFET fabrication

12:10 Design and Simulation of a 1200 V short­channel 4H­SiC DMOSFET Aamenah Siddiqui and Shakti Singh (Khalifa University of Science Technology and Research, United Arab Emirates (UAE)) In this paper, the design and simulation of a short­channel (0.5 μm) 4H­SiC power DMOSFET is presented. The design aspects  are  associated  with  trade­offs  that  are  discussed  in  the  paper.  The  structure  is  optimized  for  high  blocking voltage  of  up  to  1200  V  at  27  °C,  and  it  exhibits  off­state  leakage  currents  of  T, p.Arg481Trp and c.1792C>T, p.Arg598Cys), revealed aberrant subcellular localization of the mutant proteins, suggesting endoplasmic reticulum retention.

Preliminary  screening  data  showed  that  ShcD  adaptor  protein  associates  with  the  proto­oncogene  Ret  receptor tyrosine  kinase.  In  the  present  study,  we  aimed  to  investigate  the  molecular  interaction  between  ShcD  and  Ret  in human  neuroblastoma  and  studying  the  functional  impact  of  this  interaction.  We  were  able  to  show  that  ShcD immunoprecipitated  with  Ret  from  SK­N­AS  neuroblastoma  cells  lysate  upon  GDNF  treatment.  This  result  was validated  by  ShcD­Ret  co­localization  via  employing  fluorescence  microscope.  ShcD­Ret  association  was  shown  to have unexpectedly negative impact on various downstream signaling pathways such as AKT, PKC and ERK pathways. Interestingly,  ShcD­Ret  association  reduced  cell  viability  and  migration  in  SK­N­AS  cell  line.  However,  ShcD  was shown previously to trigger melanoma cell migration and tumorigenesis; our data showed an opposite role for ShcD in neuroblastoma SK­N­AS cells via its association with Ret. Conclusively, ShcD acts as a switch molecule in bringing a contrast biological responses, which needs further determination.

11:50 Is the Upper Half of Linguistic Stimuli Always More Informative than the Lower? Evidence from English and Arabic Maryam AlJassmi (Zayed University & Psychology, United Arab Emirates (UAE)) Previous studies have reported that when presenting just the upper or lower halves of words, the upper half is more informative than the lower half in a range of different languages. However, despite the widespread usage of Arabic, the informativeness of the upper and lower halves of Arabic words have never been reported. Accordingly, the aim of this study  was  to  investigate  the  informativeness  of  the  upper  and  lower  halves  of  Arabic  words,  nonwords  and  single letters. Arabic­English bilinguals participated in a two­alternative forced choice procedure in which Arabic and English words, nonwords and single letters were displayed in three different formats (complete, upper half, lower half). Results revealed an upper advantage for all English stimuli but a lower advantage for all Arabic stimuli. The magnitude of this upper­lower  difference  was  greatest  for  words  in  both  languages  indicating  that  these  effects  reflect  components specific to word recognition.

12:10 investigating cycle two English language teachers' perceptions about reading strategies and limitation factors hindering the use of strategies Mona Binothman and Sadiq Ismail (UAE University, United Arab Emirates (UAE)) This study investigated the perceptions of 211 English teachers about the use of various reading strategies and the possible factors that may limit the applications of those strategies in grades 6­9 in UAE's cycle 2 schools. The study also examined if there is any statistically significant difference between English non­native and native teachers' views of the use of reading strategies and the factors that may hinder the use of such strategies in their classes. Generally, the results reveal that the English teachers tend to use various reading strategies in their classes (M =4.08) although they highlighted some factors that may limit the applications of those strategies (M=3.94). The results also show that there are some statistically significant differences between native and non­native English teachers regarding the use of reading strategies in their classes and the factors that may limit the applications of such strategies.

12:30 Extensive Reading and UAE High Schoolers' Needs Assessment Mona Aljanahi (United Arab Emirates University, United Arab Emirates (UAE)) In  the  past  few  decades  Arab  educators  and  literates  have  shown  concern  claiming  that  Arabs  have  abandoned reading.  Another  level  of  perplexity  is  added  when  the  reading  is  proposed  to  take  place  in  a  second  language— English. Studies indicate that in order for students to learn to read they have to do just that— read. Much research has shown  that  Extensive  Reading  is  beneficial  for  second  language  learning.  As  such,  this  study  sought  to  answer  the question of how best to incorporate extensive reading programs in English classrooms in the UAE by examining it from a needs assessment perspective of the learners' themselves—an indispensable first step in implementing and planning educational programs. Questionnaires were used as the core mode of data collection from female and male public high school students in the UAE. Data gathered from the participants were analyzed following patterns of Borich's (1980) needs assessment model.

12:50 Measuring Urban Form Change in Abu Dhabi Lamis Abu Ashour (Masdar Institute, United Arab Emirates (UAE)) Cities like Abu Dhabi which have not grown gradually are referred to as sudden cities because they emerged instantly and keep rapidly urbanizing. Although this rapid planned development has granted Abu Dhabi the strong admiration of other countries, it has been sometimes hasty and off­balance, overlooking crucial environmental aspects. Within this context, and given urban planning's key role in achieving sustainability goals, it is rather important to operationalize theory and to perform quantitative and multi­criteria assessments, in order to provide clear direction to future growth. this paper focuses on a comparison between two superblocks that were developed at different times in Abu Dhabi: one older one on the island itself, and a recent development in the mainland. Both share a similar land use structure and have very similar size and street layout, although their overall density and functionality differs significantly.

12:10 Strain Node Identification For EOR Force Transducer ­ Experimental and Numerical Study Dima Ali (The Petroleum Institute University, United Arab Emirates (UAE)); Jamal Ahmad (The Petroleum Institute, United Arab Emirates (UAE)); Meng Fanyu (Northwestern Polytechnical University, P.R. China) The  locations  of  the  strain  nodes  on  the  extended  octagonal  ring  (EOR)  force  transducer  have  been  examined  by previous works. However, there is a lack of agreement between the two most famous methods, the analytical and the numerical. Moreover, there is a lack of agreement between the different papers using numerical method. This work is done to locate the strain nodes and consequently strain gages locations, study symmetry assumption done previously, and  examine  the  effect  of  the  direction  of  vertical  load  application  on  the  EOR.  Experimental  work  to  validate numerical solutions is still in progress.

12:30 Experimental and Numerical Modelling of the Low Energy Direct Contact Membrane Distillation Khadije El Kadi and Isam Janajreh (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Membrane  distillation  (MD)  is  appropriate  technology  for  desalination,  wastewater  treatment,  and  medicinal application. Direct contact (DCMD) is the most common membrane distillation configuration due to its simplicity, high flux,  and  low  energy  demand.  In  this  work,  a  high  fidelity  validated  numerical  analysis  using  computational  fluid dynamics  (CFD)  modelling  is  carried  out  to  assess  the  performance  of  the  DCMD.  The  model  is  validated  by  an experimental setup. In particular, the different flow velocity is considered. The results are demonstrated in terms of temperature profiles, temperature polarization coefficient (TPC), mass flux and thermal efficiency. At 75 ˚C operating feed temperature running at relatively high velocity (Re=100), 43% average thermal efficiency can be achieved.

12:50 Enhancing Pull­out Performance of Bonded­anchors via Bi­adhesive Interlayer: A Theoretical and Computational study Mohd Khan (Masdar Institute of Science and Technology); Jabir Ubaid (Masdar Institute of Science and Technology, United Arab Emirates (UAE)); Kumar Shanmugam (Masdar Institute of Science and Technology) Although bi­adhesive systems have been studied for automotive and aerospace structures, its suitability for bonded anchors  have  not  yet  been  explored.  Therefore,  in  this  study,  mechanics  of  stress  transfer  from  the  anchor  to  bi­ adhesive bondline through shear is studied via a theoretical framework. For validation, the distribution of shear stress along the bondline is compared with that of equivalent axisymmetric Finite Element (FE) models and the results are found  to  be  in  good  agreement.  The  influence  of  boundary  condition  at  the  embedded­end  of  the  anchor  in  the  bi­ adhesive bondline is studied for various bondlength ratios. Closed form expressions for shear stress distribution are presented for anchors with homogeneous bondlines. A reduction in shear stress concentration of about 40 % can be achieved by the use of bi­adhesive bonded anchors. The theoretical solution developed can be readily used to evaluate the pull­out performance of post­installed adhesive anchors.

11:50 Accurate Estimation of Partial Discharge Location using Maximum Likelihood estimation for identifying uncertainties Wisal Siyam, Mamoun Abdel­Hafez and Ayman El­Hag (American University of Sharjah, United Arab Emirates (UAE)) In this paper, an accurate location estimation of partial discharge (PD) in an oil insulation system is discussed. The study aims at identifying disturbance and uncertainties in partial discharge localization system. Initially, an extended Kalman  filter  is  used  to  estimate  the  PD  location.  The  optimal  filter  is  obtained  by  identifying  noise  statistics  using maximum  likelihood  estimation.  The  accuracy  of  the  proposed  algorithm  is  verified  by  comparing  the  estimated  PD location using assumed noise covariances and the estimated PD location using estimated noise covariances.

12:10 An Improved SVPWM­Based Voltage Balancing Approach for Modular Multilevel Converter Safia Bashir and Abdul Rahiman Beig (The Petroleum Institute, United Arab Emirates (UAE)) The emerging Modular Multilevel Converter (MMC) is considered as one of the promising topologies. Balancing of the capacitor voltage of the MMC Submodules (SMs) plays a critical role for safe operation of MMC. This paper proposes a balancing approach based on space vector PWM (SVPWM). The proposed method uses only one SVPWM to generate the switching  vectors  for  the  upper  arm  of  MMC.  The  switching  vectors  of  the  lower  arm  are  obtained  by  finding  the complement of the upper arm switching vectors, which in turn eliminates the requirement of using another SVPWM for the  lower  arm.  It  also  minimizes  the  inner  difference  current  that  results  from  the  voltage  unbalanced  between  the arms.  To  verify  the  proposed  method  a  simulation  of  MMC  was  carried  out  in  MATLAB/  SIMULINK/SIMPOWER.  The simulation results demonstrate the capability of the proposed strategy in balancing the SMs capacitors voltages and in reducing the inner difference current.

12:30 Analytical Synthesis of High­Order Low­Pass Filter Using Differential Difference Current Conveyor for Multi­Standard Receivers Sana A Alshwaikh (University of Ajman, United Arab Emirates (UAE)); Soliman Mahmoud (University of Sharjah, United Arab Emirates (UAE)) This paper presents analytical synthesis of the transfer function as new technique for realizing high order filters, by translating equations into active blocks. A 4th order low pass filter (LPF) was designed using this technique and using the differential difference current conveyor (DDCC) as its active block. The proposed filter was used in the baseband of the  multi­standard  receivers,  with  different  cutoff  frequencies  to  support  different  standards.  LT  Spice  simulation results are presented using 90nm technology, with ±0.5V supply. This filter has a total power consumption of 1mW and a DC gain of ­1 dB

11:50 Distance­Preserving Hashing Techniques Abdelrahman AlMahmoud (Khalifa University, United Arab Emirates (UAE)) Privacy  requirements  and  the  need  for  collaborative  analysis  has  motivated  a  significant  amount  of  research  on anonymization techniques and privacy­aware analysis. Anonymization techniques are typically applied to data in order to  preserve  certain  distances  and  properties  of  the  original  data  points  without  revealing  compromising  information about  it.  A  popular  family  of  approaches  in  this  field  are  distance­preserving  hashes.  These  techniques  allow  data owners  to  share  private  information  safely  while  retaining  properties  that  enable  analytics.  However,  typical anonymization techniques require a lot of expertise and domain knowledge in order to be applied effectively because they alter certain properties of the data. In this paper we discuss the types of distance­preserving hashing in order to give insight on how they operate.

12:10 Cloud Forensics: Process Misbehaviour Detection using Finite State Log Analyzer Sameera Almulla (Khalifa University of Science, Technology & Research (KUSTAR), United Arab Emirates (UAE)) In this paper, we present a Forensic Finite State Log Analyzer (FFSLA) framework to analyze cloud based web service composition  process  behaviors  and  classify  the  normal  from  non­conventional  attack  behavior.  Also,  we  will  discuss preliminary  results  of  the  proposed  framework  tests  and  evaluation.  Stakeholders  may  consider  the  proposed framework to redesign business process execution in order to mitigate risks associated with process misbehavior.

12:30 FLUKES: Automated log threat extractor tool Hesham Shaif (Zayed University, United Arab Emirates (UAE)); Monther Aldwairi (Zayed University & Jordan University of Science and Technology, United Arab Emirates (UAE)) Unstructured  server  logs  datasets  are  increasing  geometrically.  The  complexity  in  processing  and  analyzing  threats poses a challenge to security data experts and research community. This paper proposes intelligent data abstraction technique, called FLUKES, to process unstructured server logs and generate a visualization of the attack threat using opensource D3.js modules. FLUKES has been tested experimentally with server log events, specifically FTP server logs, and produced a new signature pattern of Brute­force attack. FLUKES accepts input log files in the format of .JSON and .CSV,  and  generates  representation  summary,  which  is  processed  and  visualized  throw  a  programmable  dashboard. The ultimate outcome is to forensically correlate then visualize logs and detect threats of successful access into the network without altering the original log evidence.

12:50 Advanced forensics file carving framework for fragmented video files Khawla Alghafli (Khalifa University of Science, Technology and Research, United Arab Emirates (UAE)); Ernesto Damiani (Universita’ degli Studi di Milano, Italy); Chan Yeob Yeun (Khalifa University, United Arab Emirates (UAE)) In digital forensics, file carving of video files is an important process to recover evidence of several criminal cases. The traditional carving techniques recover video files based on their file structure. However, these techniques fail in the cases if the file is split into several fragments over storage media and some of its parts were overwritten. In this paper, we present an overview of an advanced forensics video file carving framework to recover and reassemble fragmented video files into playable video files. We provide experimental results showing that the video can be recovered based on the proposed framework. The overall accuracy rate can produce forensically sound evidence and play a critical role in the process of recovery of digital evidence in many criminal cases.

12:10 Evidence Admissibility in Commercial Arbitration: Systemizing the Approach Ahmad Alozn and Abdulla Galadari (Masdar Institute of Science and Technology) Contracts  are  designed  to  govern  the  relations  between  business  partners,  allocate  risk  among  them,  and  resolve conflicts that might arise during the course of the contract. Of course, a contract cannot resolve all conflicts as it cannot predict every possible scenario and hence, dispute resolution mechanisms have been developed to assist. Arbitration, among these mechanisms, is considered the most efficient legally binding dispute resolution mechanism. Arbitration efficiency is nothing, but an agreed flexibility in the applied rules and procedures. Among this flexibility, arbitration rules  of  evidence  admissibility  that  are  very  much  decided  by  the  arbitral  tribunal.  This  paper  reviews  the  famous arbitration rules in an attempt to find common grounds with respect to evidence admissibility. It further proposes a framework to unify the approach of assessing evidence admissibility by the arbitral tribunal.

The  devices  showed  a  large  memory  window  at  low  operating  voltages  with  excellent  retention  and  endurance characteristics due to the additional oxygen vacancies in the nano­islands and the deep barrier for the trapped holes due to the reduction in ZnO electron affinity. The results prove that the ZnO nano­islands are promising in future low power memory applications.

14:40 Cytotoxicity of Nanoparticles and Carbon Nanotubes: Implications and Avenues of Characterization Nicholas Hallfors (Khalifa University, United Arab Emirates (UAE)) Nanomaterials are a class of materials with dimensions on the nanometer scale. Nanomaterials are attracting great interest for applications in medicine, electronics and energy, among other fields. As they become more popular and more  widely  produced,  it  will  be  important  to  better  understand  the  interaction  between  living  tissue  and nanomaterials. This paper reviews several recent studies on safety and biocompatibility of nanoparticles and carbon nanotubes. It is observed that many materials described as inert or biocompatible on a macro­scale setting may not be as safe at the nano­scale. From these observations, some preliminary decisions can be made on the future of certain nanomaterials.

Room: 202006 (New Ext. ­ 2nd Floor) Chair: Khalid Alhammadi (The Petroleum Institute, United Arab Emirates (UAE)) 14:00 A Simulation Environment for a Magnetically Actuated Capsule Endoscopy Yasmeen Abu­Kheil (Khalifa University, United Arab Emirates (UAE)); Lakmal Seneviratne (KURI, United Arab Emirates (UAE)); Jorge Dias (Khalifa University, United Arab Emirates (UAE)) In  this  paper,  an  augmented  human­machine  interface  and  a  virtual  simulator  for  magnetically  actuated  endoscopic capsules  are  proposed.  The  interface  provides  the  operator  with  two  types  of  feedback  information:  (i)  3D  visual information feedback through a 3D reconstructed map and (ii) 3D pseudo force feedback through a haptic device. The proposed simulation environment allows visual and haptic control strategies for capsule constrained motion in image coordinates.  The  virtual  simulation  environment  also  offers  both  off­line  training  for  medical  doctors  and  a  testing platform for researchers.

14:20 Nonlinear Estimation for Calibration of 3PRR Planar Parallel Kinematics Manipulator Abdur Rosyid, Bashar El­Khasawneh and Anas Alazzam (Khalifa University, United Arab Emirates (UAE)) Calibration is a common procedure to increase the accuracy of machine tools. Estimation as an important part of the calibration has been conducted by using various algorithms. This paper presents the implementation of nonlinear least squares  (Gaussian  least  squares  differential  correction)  algorithm  to  estimate  the  geometrical  parameters  of  3PRR planar  parallel  kinematics  manipulator  having  nonlinear  kinematics  which  can  be  used  in  a  hybrid  serial­parallel kinematics machine tool. The independent parameters are first estimated followed by the dependent parameters. The convergence to the true values with zero estimation error is guaranteed with any initial estimates provided that no measurement noise is introduced. Subsequently, the estimation by incorporating noise from all measurement devices is  conducted  which  gives  the  estimates  with  certain  estimation  errors.  It  is  shown  that  larger  size  of  measurement samples increases the estimation accuracy. Finally, the uncertainty of the estimates is evaluated by using Monte Carlo simulation.

14:40 Vision marker based Multi UAV Collaborative Aerial Manipulation Abdullah Mohiuddin (Khalifa University, United Arab Emirates (UAE)); Dongming Gan (Khalifa University of Science, Technology and Research, United Arab Emirates (UAE)); Tarek Taha (Khalifa University, United Arab Emirates (UAE)) Multi­UAV collaborative manipulation in outdoor environments, especially in absence of accurate position esti­ mation mechanisms, brings forth challenges such as dynamic stability, control techniques and algorithms of collaboration. The proposed work is an attempt to develop such an algorithm for collaboration with the help of an open source physics engine GAZEBO, where in, a previously developed simulation platform RotorS is used to simulate Hex­rotors. Multilink arms  with  alternating  joint  axes  with  zero  damping  are  used  to  simulate  a  cable  attached  with  the  Hex­rotors.  A magnetic  gripper  is  attached  to  the  cable  as  endeffector  and  a  node  is  developed  already,  demonstrating  the hardcoded  picking,  transportation  and  dropping  of  the  payload.A  comparison  is  performed  amongst  mechanical coupling,  vision  marker  based  method  and  the  perfect  position  estimation  method  for  collaborative  aerial manipulation.

15:00 Decision Making with Multi­agent in Search and Rescue A Multi­Objective POMDP Approach Hend Al Tair, Tarek Taha, Jorge Dias and Mahmoud Al­Qutayri (Khalifa University, United Arab Emirates (UAE)) In this paper we propose a method to reinforce preference of objectives using the reward function of a Multi­Objectives Partially Observable Markov Decision Process (MOPOMDP). The technique is applied in context of search and rescue that involves heterogeneous team with multi­objective with potential conflicting­objectives situations. It ensures that a high­priority preferences get high accumulative rewards, solve ambiguities and it can be conducted before the low­

priority­preference. We used existing POMDP solver to solve the problem. The algorithm has been tested for a 50 test case to show its effectiveness

15:20 Cord Grounding Unit (CGU): A Novel Design for Energy­Efficient Unidirectional Selective­Self­Locking Mechanism Mohammad Awad (Khalifa University of Science Technology and Research, United Arab Emirates (UAE)); Dongming Gan (Khalifa University of Science, Technology and Research, United Arab Emirates (UAE)); Jorge Dias (Khalifa University, United Arab Emirates (UAE)); Lakmal Seneviratne (KURI, United Arab Emirates (UAE)) In  this  paper,  the  Cord  Grounding  Unit  (CGU)  mechanism  is  presented.  CGU  is  a  novel  design  for  energy  efficient unidirectional selective self­locking mechanism. The novelty lies in the design and functionality of the CGU. The CGU is consisted of a cam­cleat, which is retracted away from the cord motion space by a leaf spring. When locking is required, a linear solenoid actuator pushes the cam­cleat towards the moving cord. The engagement between the cam­cleat and the moving cord will move the cam­cleat towards its space­eliminating region, this will block the motion of the cord creating a new grounding point. The application of CGU in robotics can vary from safety to stiffness altering depending on the intended application. Energy efficiency is guaranteed due to short actuation time of the linear solenoid (single second) as the locking process is passively occurring through the engagement between the moving cord and the cam cleat.

14:20 Chain­wide Optimization of Procurement, Production, and Dispatching Decisions Under Consignment Stock Partnership Osama Alkhatib and Rami As'ad (American University of Sharjah ­ UAE, United Arab Emirates (UAE)); Moncer Hariga (American University of Sharjah, United Arab Emirates (UAE)) This paper seeks to jointly optimize the operational decisions associated with raw material procurement, production lot sizing as well as finished product dispatching for a two layer supply chain comprised of a single­vendor and a single­ buyer. As per the just­in­time replenishment policy, a raw material quantity enough to cover exactly the production during  one  cycle  is  ordered  at  the  beginning  of  each  production  cycle.  In  this  paper,  however,  a  more  general  raw material  replenishment  schedule  is  considered  wherein  multiple  raw  material  shipments  may  take  place  within  one cycle,  referred  to  as  multi­to­one  (MTO)  policy,  or  alternatively  a  single  shipment  that  covers  the  production  for multiple cycles, referred to as one­to­multi (OTM) policy, may rather be adopted depending on whichever is optimal. The aforementioned decisions are simultaneously optimized through mathematical models that embrace the integer multiplier of the cycle time policy.

14:40 Achieving Sustainable Transportation Goals for Abu Dhabi: A Study of Public Transit Use Praveen Maghelal (Masdar Institute, India); Mayada Almardood (Masdar Institute, United Arab Emirates (UAE)) Abu  Dhabi,  capital  city  of  United  Arab  Emirates,  is  an  emerging  global  city.  As  part  of  its  identity,  the  city  aims  to provide  world  class  facilities  and  services  in  the  region,  including  a  good  network  of  public  transportation. Understanding  the  transit  user  perception  will  provide  service  recommendations  and  help  identifying  the  trip characteristics,  travel  behavior  and  perceptions  that  can  enhance  current  transit  system  and  provide  future recommendations  for  effective  transit  network.  Due  to  the  lack  of  information  about  the  patterns  of  transit  use  by individuals  in  Abu  Dhabi  City,  this  study  uses  the  transit  user  stated  preference  survey  to  examine  the  trip characteristics; travel behavior; perception of quality of service, social network and personal characteristics of transit users  of  Abu  Dhabi.  The  analysis  of  respondents  provides  insights  into  the  housing  development,  transit  service enhancement and creating transit­oriented development within walkable distance of transit stops.

15:00 Multiple Plants Capacitated Lot Sizing and Scheduling With Sequence­Dependent Setup Costs Sari Abdullah, Abdulrahim Shamayleh and Malick Ndiaye (American University of Sharjah, United Arab Emirates (UAE)) Production  planning  is  a  crucial  activity  for  companies  to  satisfy  customers  demand  while  minimizing  cost.  The objective  of  this  research  is  to  optimize  the  production  planning  and  scheduling  decisions  of  companies  in

65

petrochemical industry field. A Mixed­Integer Linear Programming (MILP) model is developed for the capacitated lot sizing and scheduling problem with sequence dependent setup costs where changeover cost occurs when changing the production from one grade to another. The model considers the chain of multiple suppliers, affiliates, warehouses, and customers.  It  provides  answers  to  questions  regarding  the  amount  of  each  raw  material  to  be  purchased  from  each supplier, the sequence of production plans, inventory levels, and warehouse selection to satisfy orders. The problem under study is considered an NP­Hard problem due to its complexity and size; therefore, a three stage heuristic was developed which provided good quality solutions with a range of 0.09% ­ 2.0% away from optimality.

15:20 Predicting Accessibility:A Hierarchical Additive Approach Anoud Alqahtani (Masdar Institute, United Arab Emirates (UAE)); Praveen Maghelal (Masdar Institute, India) Accessibility, as a conceptual and operational definition, has gone through several iterations. However, it still remains as an often misunderstood and poorly defined and measured construct. In general, it is understood that accessibility is a  measure  of  spatial  distribution  of  potential  destinations,  the  ease  of  reaching  these  destination  (individually  or collectively)  and  the  magnitude,  character,  and  quality  of  various  activities  existing  in  that  particular  geography. Currently, four perspectives of measuring accessibility exists: Infrastructure­based, location­based, person­based and utility based. Location­based accessibility is the most commonly used measure because it is easier to access since it is less  data  intensive  and  easy  for  researchers  to  communicate  and  comprehend  the  implications.  Masdar  city,  when developed  as  planned,  will  consists  of  several  types  of  sustainable  transportation  options  including  walking,  biking, personal rapid transit, group rapid transit, bus/light rapid transit and metro. The planned city is divided into grids of 400m using the contour approach.

T­SD3: Mechanical Engineering

Room: 202022 (New Ext. ­ 2nd Floor) Chairs: Imad Barsoum (The Petroleum Institute, United Arab Emirates (UAE)), Mohamed Sassi (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) 14:00 Application of the POD Method for Damaged Detection in Cracked Rotor Systems Ayesha Al Mehairi (KUSTAR, United Arab Emirates (UAE)); Adnan Saeed (Khalifa University, United Arab Emirates (UAE)); Shadi Balawi (Khalifa University of Science, Technology & Research (KUSTAR), United Arab Emirates (UAE)); Mohammad Alshudeifat (Khalifa Universiy, United Arab Emirates (UAE)) Unusual vibration levels in rotating equipment usually result from unbalance, misalignment, mechanical loose­ ness, propagating  cracks  and  other  sources  of  malfunctions.  Appearance  of  these  damages  often  excites  destructive vibration  amplitudes  in  rotor  systems.  Here,  we  focus  on  the  induced  vibration  by  propagating  cracks  in  a  rotating shaft. Detecting crack in its early phase of propagation might help in preventing further damage in the equipment as well as avoiding economic and human losses. The proper orthogonal decomposition (POD) is employed here as a crack detection technique for early damage detection and to identify the vibration signature of the cracked rotor response.

14:20 Computational Modelling of Anode Baking Furnace (ABF) Performance Abdul Raouf Tajik (Masdar Institute of Science and Technology, United Arab Emirates (UAE)); Tariq Shamim (Masdar Institute of Science & Technology, United Arab Emirates (UAE)); Mouna Zaidani and Rashid Abu Al­Rub (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Anode baking is a critical step in production good quality of carbon anodes which are needed for aluminum production. The operational and geometrical parameters have significant influence on the anode baking furnace (ABF) performance and the resulting carbon anode quality. Numerical modelling is an imperative tool to investigate the effect of different parameters on the anode baking process. This study provides an overview of two different approaches employed in ABF modelling namely process modelling, and design modelling. Using process modelling, in a simplified manner, effect of several operational parameters on anode baking process are investigated. ABF design modelling concentrates on effect of different furnace design on baking process.

14:40 Finite Element Analysis of a Pressure Vessel Subjected to Internal Blast Loading Sadiq Lawal, Imad Barsoum and Rodney Simmons (The Petroleum Institute Abu Dhabi, United Arab Emirates (UAE)) The  current  numerical  study  was  necessitated  because  of  a  non­injury­producing  incident  which  occurred  in  a laboratory, where an autoclave exploded during an experiment titled: "Autoclave­Assisted Thermal Decomposition of Ammonium Tetrathiomolybdate and Carbon Nano Tubes Impregnation". The explosion was believed to have occurred because  dimethyl  sulfoxide  (DMSO)  was  used  in  excess  in  the  experiment  and  heated  beyond  its  decomposition temperature. The aim of this current study therefore, is to investigate the effect of internal blast load on a pressure vessel  made  of  stainless  steel  AISI  316L  through  finite  element  analysis.  Numerical  simulation  using  FEA  was performed to better understand the true cause of failure of the pressure vessel. The result of the finite element­based analysis  that  reasonably  predicts  the  structural  response  and  subsequent  failure  of  the  pressure  vessel  that  was observed in the post­incident investigation was presented.

15:00 Development of a Backward Whirl Based Damage Detection Technique in Rotor Systems Hanan Al Hosani (R&D Engineer at ETiC, United Arab Emirates (UAE)); Adnan Saeed (Khalifa University, United Arab Emirates (UAE)); Mohammad Alshudeifat (Khalifa Universiy, United Arab Emirates (UAE)); Shadi Balawi (Khalifa University of Science, Technology & Research (KUSTAR), United Arab Emirates (UAE)) Studying  the  dynamic  behavior  of  cracked  rotor  systems  has  gained  great  interest  in  the  literature.  The  extensive applications of heavy­duty rotor dynamic systems in different industrial and aerospace rotating equipment could lead to crack catastrophic crack­based damages. Early detection of cracks in a cracked rotor in engineering practice is of

66

significant  importance  to  the  safety,  reliability  and  durability  of  large  rotating  machinery  in  service.  The  proposed backward­whirl approach could help in detecting early crack damages in rotor system, by identifying a unique crack signature based on backward whirling analysis.

15:20 Trickle Bed Reactor Operational Mode Characterization ­ Pressure Fluctuation Analysis Amena Hasan (Masdar Institute, United Arab Emirates (UAE)); Shahid Rabbani and Mohamed Sassi (Masdar Institute of Science and Technology, United Arab Emirates (UAE)) Trickle Bed Reactors used in the industry are significant to many processes. Understanding the hydrodynamics of the reactor allows a more efficient design and operation of the reactor. A smart sensor can provide a deeper knowledge of the operation in a reactor. This work investigates the flow regime and structure by analyzing the pressure fluctuation in the reactor. The method used involves using COMSOL as a software simulation. The simulation applies the Level Set Method and will track locally the wettability and pressure fluctuation. Eventually this data is to be validated with the smart  sensor,  hence  the  data  to  be  measured  by  the  smart  sensors  will  provide  a  direct  implication  based  on  the analysis in this work.

Room: 202023 (New Ext. ­ 2nd Floor) Chairs: Tarek El Fouly (Khalifa University, United Arab Emirates (UAE)), Bashar Zahawi (Khalifa University, United Arab Emirates (UAE)) 14:00 Frequency Domain Analysis of a Guyed Tower Subjected to a Lightning Strike Andri Haryono, Noureddine Harid and Huw Griffiths (Petroleum Institute, United Arab Emirates (UAE)) This  paper  reports  the  simulation  results  of  a  guyed­wire  telecommunication  tower  located  in  a  high  flash  density region and subjected to lightning strikes. This study is a response to incidents which occurred within few guyed towers in several locations in the region, and which resulted in severe damage to the electronics connected to the tower. This study intends to develop new protection measures for the guyed tower. The aim is to elucidate the possible reasons that  led  to  such  damage  and  recommend  protection  measures  to  improve  LPS  performance.  Frequency­domain computations are carried out using frequencies representative of the typical lightning current. Hybrid approach is used to compute the GPR at the surface of conductors and inductively induced potentials and currents on adjacent coaxial cable. The results show that, large potential differences in excess of the maximum withstand level of the insulation may occur between the cable core and sheath.

14:20 Preliminary soil resistivity measurements for assessment of non­linear effects of current magnitude and frequency Mohammed Abu Geyab, Huw Griffiths and Noureddine Harid (Petroleum Institute, United Arab Emirates (UAE)) Commercial  earth  resistivity  test  equipment  have  relatively  narrow  ranges  of  test  frequency  and  magnitude  of  the injected  current.  A  research  program  has  been  initiated  to  investigate  the  effect  of  varying  the  frequency  and magnitude  of  the  injected  current  on  the  measured  apparent  resistivity.  Firstly,  a  conventional  'roll­along'  soil resistivity  survey  was  carried  out  over  6  survey  lines  at  a  designated  test  site  at  the  Petroleum  Institute  using  an ABEM  Terrameter  LS.  A  '2.5D'  visual  model  was  generated  using  VOXLER  software.  The  results  are  analyzed  and indicate  clearly  the  presence  of  the  water  table.  The  proposed  future  work  consisting  of  a  systematic  field  test investigation  into  the  effects  of  varying  current  magnitude  and  frequency  is  described  and  the  associated  computer simulations using numerical­based grounding software. The work is expected to lead to recommendations on optimized test parameters for commercial soil resistivity testers possible alternative improved test setups/techniques.

14:40 An Alternative Measurement Approach to Sweep Frequency Response Analysis (SFRA) for Power Transformers Fault Diagnosis Abdulla Hammoud (The Petroleum Institute & The Petroleum Institute, United Arab Emirates (UAE)) The power transformer is an expensive component in the power network and its failure can lead to power outages and significant financial loss, particularly at higher voltage levels. Frequency response analysis (FRA) is a recommended technique to diagnose transformer faults and particularly so for detecting mechanical displacements in windings and core.  However,  due  to  the  complex  way  in  which  transformer  electric  parameters  (inductance,  capacitance,  and resistance)  are  affected  by  such  distortion,  challenges  remain  in  the  correlation  of  FRA  signature  and  fault  type. Furthermore, FRA is influenced significantly by the adopted measurement method and practical test setup. This paper aims  to  investigate  FRA  responses  of  small  laboratory  test  transformers  measured  using  a  standard  'IEEE' recommended method and with a proposed new generic test setup having additional current measurement points and using  precision  lock­in  amplifiers.  The  paper  also  presents  results  showing  the  effect  of  change  in  the  magnitude  of applied voltage levels.

15:00 Surface Discharge Detection using UHF Method Alaa Atef (The Petroleum Institute, United Arab Emirates (UAE)); Huw Griffiths and Noureddine Harid (Petroleum Institute, United Arab Emirates (UAE)) Reliable  operation  of  high­voltage  power  system  equipment  depends  on  the  integrity  of  its  insulation.  During operation, the insulation is exposed to electrical, thermal, chemical and mechanical stresses. Electrical stress is the main  factor.  This  occurs  as  partial  discharges  (PD)  generated  as  a  result  of  high  electric  field  stress.  Monitoring  the insulation of electrical equipment in the high­voltage system is essential for maintenance purposes and for improving the  reliability  of  the  system.  In  this  paper,  an  experimental  study  on  the  characteristics  of  surface  discharge  is presented. A test set­up using a solid dielectric sample in a point­plane configuration was used to generate surface PD and  the  effect  of  voltage  amplitude  are  examined.  The  results  are  analyzed  using  signal  processing.  Also,  the electromagnetic fields radiated by this type of discharge were computed using the FDTD method. These may help in evaluating the sensor characteristics required for detecting surface discharges in practice.

15:20 PDE Based Model of Artificial Gas Lift Dynamics Ibrahim AbuShawish (The Petroleum Institute, United Arab Emirates (UAE)); Igor Boiko and Ahmed Al­Durra (Petrolum Institute, United Arab Emirates (UAE)) A new model to describe the dynamics of the artificial gas lift systems based on PDEs, fluid equations of state and the plastic bag method of discretizing the PDEs with respect to time and space is proposed. This model shows high fidelity and  accurate  results  in  comparison  to  the  Original  Plastic  Bag  model  due  to  its  ability  to  properly  and  accurately describe the behavior of oil and gas based on well­known correlations that define their properties. Operating points map is present to show the behavior of the oil and gas in the AGL systems. Comparison between the proposed model and the Original Plastic Bag model is shown.

T­SF3: Computer and Information Systems

Room: 202024 (New Ext. ­ 2nd Floor) Chair: Haseena AlKatheeri (Zayed University, United Arab Emirates (UAE)) 14:00 Lightweight Security Protocol for A Biosensor Hussam Al­Hamadi (Khalifa University & Information Security Research Center, United Arab Emirates (UAE)); Amjad Gawanmeh and Mahmoud Al­Qutayri (Khalifa University, United Arab Emirates (UAE)) Security  is  one  of  the  major  challenges  that  affect  the  deployment  of  the  biosensors  that  form  WBSNs.  The implementation of any security protocol comes along with the additional overhead of an extra power consumption from the  limited  resources  of  devices  like  biosensors.  Nevertheless,  the  additional  security  operations  may  come  with  a delay that affects the real­time objective of the biosensors application. In this paper, a lightweight security protocol is presented  to  secure  the  medical  information  which  is  transmitted  from  the  biosensor  to  the  gateway.  The  proposed security protocol relies on a counter method at the biosensor side to save the biosensor's power. The security protocol shouldn't include unnecessary computational processes to has an acceptable cost of computational delay. Therefore, the performance of the proposed protocol is compared with that of other existing techniques.

14:20 Survey of Incentive Mechanisms for Crowd Sensing Ahmed Suliman (Khalifa University, United Arab Emirates (UAE)); Hadi Otrok (Khalifa University, United Arab Emirates (UAE) & CIISE, Concordia University, Canada) With the wide spread of smart phones, the paradigm of crowd sensing is gaining immense popularity. Crowd sensing is the  act  of  collecting  certain  kind  of  data  from  people  in  a  specific  area  of  interest.  Since  the  users  involved  in  this activity incur a cost for performing the task, i.e. the cost of uploading the data or the energy to sense, they need to be compensated for their work or else they will not be inclined to participate in the sensing task. Many papers have been published  related  to  user  selection  and  incentive  mechanisms  in  crowd  sensing.  In  this  paper  we  review  a  range  of approaches proposed in both areas, provide comparison between them and outline areas for future work.

14:40 Automatic arabic Text Summarization Based on Noun Extraction Lamees Al Qassem and Hassan Barada (Khalifa University, United Arab Emirates (UAE)); Di Wang (Khalifa University & EBTIC, United Arab Emirates (UAE)); Ahmad Al­rubaie and Nawaf Almoosa (Khalifa University, United Arab Emirates (UAE)) This paper focuses on discussing the challenges faced in summarizing Arabic documents and the literature in this field, which  is  fairly  limited  and  very  recent.  The  reviewed  systems  are  classified  based  on  the  methodology  followed  in building the system. Finally, a new system architecture is proposed and discussed. The system relies on the extracting nouns and clustering them based on their semantic.
