Pioneer IBC researchers have proposed two types of methods, which are galvanic coupling and capacitive coupling. This paper compares and evaluates a binary frequency-shift keying (BFSK) modulation signal using galvanic and capacitive coupling via IBC for foot plantar pressure sensors. The results of the experiment would guide us as to which method of IBC is more suitable for the specific application. The communication system is designed for foot pressure measurement to analyze pressure distribution during everyday life activities. The research targets IBC operating in the band of 1MHz to 100MHz, and based on the empirical evidence; for this particular application, galvanic coupling shows more promising performances in power, total harmonic distortion and signal-to-noise ratio measurements.","PeriodicalId":316751,"journal":{"name":"2013 7th IEEE GCC Conference and Exhibition (GCC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132238575","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 main goal of the algorithm is to minimize the return loss below -10 dB for better impedance matching. The designed antenna was miniaturized to (47×47 mm2) and simulated on low cost FR4 substrate. The algorithm implementation was achieved by MATLAB™ software and the electromagnetic simulation was carried out based on the Finite Difference Time Domain (FDTD) technique by CST Microwave Studio software. Finite Element Method (FEM) employed by the frequency domain electromagnetic software HFSS was used to verify the results. The simulation reveals UWB impedance matching exceeding 10 GHz with omni-directional radiation pattern.","PeriodicalId":316751,"journal":{"name":"2013 7th IEEE GCC Conference and Exhibition (GCC)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114655536","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}

With sophisticated modern methods being developed to reduce the energy consumption of such electrical load, the research is concerned and applied to the case of Bahrain's electrical grid system. The paper investigates two systems which are using new technology in the air conditioning system to reduce peak load and to avoid risks of peak load. This risk will increase losses in the electric grid and can be considered as a major risk is shutdown which is catastrophic for any electric grid. These two systems are solar air conditioning system and electronic air conditioning system. The paper provides a full explanation of the proposed regulations together with the study and comparison of two systems in terms of ability to reduce peak load and optimal cost-effective. The investigation recommended the use of DC inverter air conditioning system in Bahrain because it can be considered as the most cost effective.","PeriodicalId":316751,"journal":{"name":"2013 7th IEEE GCC Conference and Exhibition (GCC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116919408","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 increased penetration of wind power into the utility grid brings challenges such as voltage and frequency fluctuations, generator torque ripples, and grid faults to power converter design in wind energy conversion systems (WECSs). Multiphase PM generators offers a promising solution to many challenges due to their inherited advantages over the three phase counterparts including reduced converter per leg rating and reduced torque ripples, which directly affect the lifetime of the drive train. In high power applications, direct drive PM generators are usually employed. Among different topologies of power converters, current source converter features a simple converter structure, low switching dv/dt, and reliable short circuit protection. In this paper, a new wind energy conversion system is proposed based on a direct drive five-phase PMSG connected to the grid using current source converters (CSCs). The generator side converter, operating in the rectification mode (CSR), is controlled to control the DC-link current, while the grid side converter, operating in the inversion mode (CSI), controls the active and reactive powers injected to the grid. The five-phase generator side converter is controlled using sinusoidal pulse width modulation (SPWM), while conventional space vector modulation is employed to control the three-phase grid side. A 5 MW system with typical system data is simulated via MATLAB/SIMULINK to validate the proposed topology.","PeriodicalId":316751,"journal":{"name":"2013 7th IEEE GCC Conference and Exhibition (GCC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127381443","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}

More recently, high-definition (HD) cameras are used for providing better performance in ANPR system. However, most known approaches for standard definition (SD) number plate localisation (NPL) are not suitable for real-time HD image processing as the real-time requirement cannot be met due to the computationally intensive cost of localising the number plate. In this paper, a solution to link previously designed architectures for NPL, character segmentation and character recognition in a SD ANPR system is first described. The system is to be implemented on a single stand-alone FPGA-based processing unit. An approach to extend the SD ANPR system to HD ANPR system without significantly increasing the computational cost is then introduced.","PeriodicalId":316751,"journal":{"name":"2013 7th IEEE GCC Conference and Exhibition (GCC)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123592848","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}

A novel soft decision rule based on the covariance matrix of the SUs observations is proposed. By using the proposed scheme, we derive two Generalized Likelihood Ratio (GLR) detectors and then, we obtain the closed-form expressions for the detection and false-alarm probabilities. The proposed collaborative sensing method can control the available trade-off between efficient spectrum usage and more accurate spectrum sensing, which is not possible in the other counterpart collaborative sensing methods based on the soft decision rule. In order to have the best performance in the terms of spectral efficiency, power efficiency and spectrum sensing, we study the problem of designing the fusion parameter, the decision threshold and the number of SUs to maximize power efficiency and spectrum usage efficiency under the constraint that the Primary User (PU) is sufficiently protected. Finally, we provide the computer simulations to verify the validity of the obtained results.","PeriodicalId":316751,"journal":{"name":"2013 7th IEEE GCC Conference and Exhibition (GCC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126552384","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}
