Solar PV is one of the most widely used renewable energy resources. The output of a panel is highest when the incident ray is perpendicular to the panel plane. Due to variations in the locus of the sun over the year, the alignment of the panel should be changed according to the sun position for maximum generation. However, changing the tilt angle needs single axis tracker or double axes tracker which is costly and also needs maintenance; thus may not be suitable. Therefore, the panel is kept at the average tilt of year at which the ray is perpendicular for the maximum time. This may be termed as the default tilt angle. The generation of solar panel varies over the year providing maximum generation at the default tilt angle. Similarly, the consumption of an area is also varies over the year. The amount of generation may not proportional as the demand, thus it results surplus or shortage. For an isolated area, it is hardly possible to use surplus energy considering certain demand profile. Even, it is not possible to store the surplus energy of a season to any device for long time to use it for another season. However, the surplus energy of a season may be shifted to the shortage season by changing the tilt angle. Different tilt angle will provide different pattern of generation over the year. The generation at optimum tilt angle will not maximize the generation of energy over the year rather it will maximize the demand met by shifting the energy to shortage season from surplus season. A new concept to maximize the energy usage from solar PV by changing the tilt angle and thus minimize the shortage to meet the demand of an isolated power system is also introduced here.","PeriodicalId":125353,"journal":{"name":"2015 International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121203537","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}

In this research work, we have remodeled the guard channel scheme in different aspect and shown that there is some valuation faults in the conventional mathematical models of guard channel scheme. Then we have focused our prime concern to the different average channel holding time of handover calls and new calls as well as their effect in the estimation of QoS parameters. Thereafter we propose an idea to recalculate the average channel holding time in case of different values for handover calls and new calls. We have also revealed that there is no effect in handover call dropping probability estimation even the average channel holding time of new calls and handover calls are different. On the other hand, we have found that there is a major impact in new call blocking probability for different channel holding time for handover and new calls where our offered theory is able to reduce the effect.","PeriodicalId":125353,"journal":{"name":"2015 International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122624309","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}

It affects not only the working of adjacent loads but also shorten the life of power equipment by creating excessive losses. In this paper, a fuzzy controlled shunt active power filter is described to maintain the (Total Harmonic Distortion) THD within the allowable limits defined by IEEE Std. 519-1992 and to reduce reactive power and improve power factor. This Filter draws the opposite harmonics containing current from the load so that source current remain sinusoidal and undistorted. Fuzzy logic controller is used to control the shunt active power filter and the performance of the shunt active filter control strategies has been evaluated in terms of harmonic mitigation and DC link voltage regulation. New MATLAB code is generated for the controller. Three-phase reference current waveforms generated by proposed scheme are tracked by the three-phase voltage source converter in a hysteresis band control scheme. A fully functional MATLAB based Simulink model of Shunt Active Power Filter for different types of load (nonlinear, unbalance, both) has been designed based on `Instantaneous Power Theory' or `p-q Theory'. The results of simulation comply with all the features described by the theory, justifying employment of Shunt Active Power Filter (SAPF) in the industry.","PeriodicalId":125353,"journal":{"name":"2015 International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128161925","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 designed 13μm×8μm photonic crystal has a square lattice of GaAs rods in air with refractive index of 3.40 at operating wavelength of 1.55 μm. The lattice constant, a = 0.540 μm and radius of rods, r = 0.185a μm are chosen so that a large band gap for a TE polarized wavelength range of 1.23 μm to 1.80 μm can be obtained. The Finite Difference Time Domain (FDTD) and Plane Wave Expansion (PWE) methods are used to analyze the behavior of the structure. At first the performance of NOT logic gate is realized using different amplitude concept showing maximum transmittance of 36% for logic High. Then the performance of the same NOT gate is realized using different phase concept for logic implementation. After applying different phase definitions, it is shown that 180° and 90° phase difference between port signals can offer maximum transmittance of 69% and 55% respectively for the designed structure. So 180° phase difference is chosen for the designed NOT and XOR gates to ensure maximum transmittance for logic High.","PeriodicalId":125353,"journal":{"name":"2015 International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124809821","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}

In this paper, we propose an activity recognition framework based on extremely randomized trees and guided random forest to recognize both simple and complex activities from wearable sensor. In order to recognize different activities using extremely randomized trees, we first select most important features from all available features applying the feature selection method, namely, guided random forest; then, selected features are used to build the classifier for classifying activities. The proposed framework is extremely efficient in terms of recognition performance and computational time as it can recognize both small and large set of activities very accurately with different number of features in different sensor settings, while it needs fairly small amount of time for training and classification. The evaluation results of the experiments conducted on four benchmark data sets indicate that the proposed technique performs better than the classic activity recognition systems with respect to recognition accuracy and computational time; the proposed approach yielded the maximum recognition rate of 99.6%.","PeriodicalId":125353,"journal":{"name":"2015 International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"32 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114088421","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}
