This paper presents the preliminary outcomes of our investigations into the potential of using nuclear magnetic resonance (NMR) principles for the noninvasive measurement of blood glucose level in humans. The initial phase of the research involved testing the feasibility of using NMR in measuring glucose concentration in water. Then, the method was modified to enable us to measure the glucose level concentration in humans. Various signal processing methods were tested to find the best algorithm that improves detection accuracy. Results obtained from two human subjects are used to demonstrate the feasibility and found to be promising with error varying between 3% and 14%.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116259407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A sustainable hybrid/ off grid power generation systems suitable for a remote coastal area in Oman","authors":"Radha Rani Gogula","doi":"10.1109/IEEEGCC.2015.7060054","DOIUrl":"https://doi.org/10.1109/IEEEGCC.2015.7060054","url":null,"abstract":"This paper provides Energy-Economic Optimization for a hybrid/ off grid power generation systems using reliable renewable energies suitable for a remote coastal area, Musandam Peninsula situated in most northerly point of Oman. There is a diesel power plant located in Khasab, one of the four wilayyats of Musandam Peninsula which serves the required electricity for the region as it is an off-grid area. Renewable energies offer an alternative solution for fossil fuels. Oman is looking forward for green energies evidently along with rest of the world due to obvious reasons like increase in carbon deposits, global warming and pollution etc. An effort has been made to investigate whether the power generated by renewable energies especially by solar & wind energies available in Musandam Peninsula can replace the situation of power generation by fossil fuels. Tidal power is not considered in comparison with wind energy and solar energy, as it is not a big sustainable resource due to environment impacts & exergy availability etc. at present. Three options and their comparison have been provided with the help of `Homer software' simulation results. Simulation results based on Energy-Economic Optimization show, case studies and their comparison for three models: First model (Diesel power system), second model (Solar PV power system) and the third model (PV-wind hybrid power system). Cycle charging strategy is considered in all models. Simulation results are showing that cost of energy (COE) is lowest for PV-Wind hybrid power system. We conclude that a properly planned hybrid system combining renewable energies solar energy & wind energy (i.e. PV-wind hybrid power system) joined with conventional energy system will reduce the overall cost along with many benefits like carbon reduction etc. It is suggested in this paper to connect PV-wind hybrid power system with the existing diesel power station at Khasab and utilize the existing distribution system to meet the growing energy demand. The excess power generated can be stored in storage batteries as a backup or this power can be distributed to the nearby off-grid areas.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124610964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the instruments that helps the operator to keep frequency and voltage in specified range is Flexible Alternating Current Transmission System (FACTS). Magnetically Controlled Shunt Reactor (MCSR) is a type of FACTS devices which is widely used for avoiding the overvoltage and, therefore, increasing the voltage stability without switching or taping via fixed reactors. This advantage and other benefits of MCSR help the system operator to have a flexible operation, and prevent the occurrence of overvoltage in network; however, replacement of each fixed reactor with MCSR has never been justified financially. In this paper, a new method for determining the best location of installing a MCSR and its capacity with consideration of technical and economical criteria are proposed. Besides, the proposed technical criteria in this paper are in compliance with MCSR characteristics and benefits. In purpose of decision making in the Scenario based algorithm, the combination of AHP and TOPSIS methods is used. The proposed method for determining the best location of MCSR is applied in IEEE 9 bus system and the integrated transmission network of Iran as a practical study.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132403204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study considers different patterns of dynamic shade; low, medium and heavy, different types of inverters; central, string and micro-inverter, and different series and parallel connections of the PV modules. A comparison regarding the cost is made, in order to choose the optimal connection for the whole system. A field test was made for a NU-SOE3E Sharp Module, to measure how the current and voltage change as the module was exposed to different patterns of shade; it was shown that if only one cell is under shade, the voltage drops by third. The study proved that for a large scale PV system under different types of shades, the output power of string inverters are higher than the output power of micro-inverters and central inverters. For a small scale PV system, the output power from micro-inverters is higher than from string inverters, but the comparison showed that PV systems with micro-inverters are more costly.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128632468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces the 5-phase, (10-pulse), uncontrolled ac to dc line commutated rectifier fed from five-phase source which emulates the five-phase wind turbine generator when operates at fixed wind speed. A 5-phase shunt active power filter (APF) is connected to the point of common coupling, (ac-side), to improve the power factor and supply current total harmonic distortion (THD).

The integration of new sources and technologies are needed to satisfy the utility requests and to decrease the use of fossil fuel sources. One of the main challenging issues in integrating wind power sources is how to forecast the long-term wind speed and study its impact on the reliability of the load. In this paper, the Auto-Regression and Moving Average (ARMA) model is used to forecast the wind speed for Dhahran area in Saudi Arabia. Then, the wind power is simulated using the speed-power curve. Finally, the impact of the forecasted wind power on the reliability of residential, commercial, and industrial loads is assessed using Monte Carlo simulation.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124328550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
