VFTOs of the GIS are calculated using EMTDC/PSCAD software. Hence, the suppression of the VFTOs is also an important field of interest. The suppression techniques to reduce the VFTOs are also discussed in this paper.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"74 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85988863","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 important property of Haar wavelet is the multi-resolution. The major challenge in this video coding is motion management using HWT. Here we can reduce the expense during the storage of video data's and also reduce the bandwidth. A new method is introduced in this paper and a sub-band coding approach is also used that contains Haar Wavelet Transform (HWT) and it is related to a discrete sign coding known as DSC from wavelet. To avoid the problem created by the lack of invariance alteration, we use motion compensation (MC) technique. The output shows that the PSNR and clarity become good compared to other techniques.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"48 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86317921","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 system retrieves an image when the similarity between the query image and database images is observed. In the concluding section, we propose a new approach based on texture classification which helps to improve the accuracy and efficiency of CBIR system.

From anti-skimming defend systems to silent indicate systems, integrated ATM video surveillance cameras and ATM monitoring options, security specialists are ready to help the people get more out of the ATM security and ATM loss prevention systems. The implementation is achieved with the use of Machine-to-machine (M2M) communications technology. M2M communications is a topic that has recently attracted much attention It provides real-time monitoring and control without the need for human intervention. The idea of M2M platform suggests new system architecture for positioning and monitoring applications with wider coverage and higher communication efficiency. The aim of the proposed work is to implement a low cost stand-alone Embedded Web Server (EWS) based on ARM11 processor and Linux operating system using Raspberry Pi. It offers a robust networking solution with wide range of application areas over internet. The Web server can be run on an embedded system having limited resources to serve embedded web page to a web browser.

However, introduction of CCPPs in power systems has a significant impact on dispatch strategies as CCS consumes energy for their operation though they reduce emission. In this work a Modified Imperialistic Competition Algorithm (MICA) based solution procedure is proposed for solving multi-objective Economic Emission Dispatch problem (EED) in a power system with CCPP. A fuzzy set theory based selection method is adopted for selecting the best compromise solution out of a set of non-dominated Pareto solutions of EED problem. Proposed approach is implemented on a 6-generator test system. Results demonstrate the effects of CCPP on economy and emission of the system and effectiveness of MICA in handling multi-objective non-linear optimization problems.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88176436","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 proposed resonant power converter integrates a single-switch with Zero-Voltage Switching (ZVS) and Zero-Current Switching (ZCS) by an energy-blocking diode. The converter enhances the energy conversion efficiency with less switching losses using single ended structure by achieving soft switching technique. The converter has been demonstrated under different operating modes with an equivalent circuit. Moreover, this converter is conveniently interfaced with Photo-Voltaic (PV) system for promoting the green energy. The sun radiates more photons which is more sufficient to meet the energy demand. But, solar energy has certain intermittency issues, not shining at night and also during daytime there may be cloudy or rainy weather and partial shadow effects which affects the performance of the system. But, due to this Partial Shading Conditions (PSC) there are multiple peaks and multiple steps in the Power-Voltage (P-V) & Current-Voltage (I-V) characteristics curve respectively. One way to enhance the systems performance is by operating the PV system at its Maximum Power Point (MPP). This can be achieved by incorporating a suitable MPPT control algorithm along with the converter circuit. Here, the Incremental Conductance (I&C) and Particle Swarm Optimization (PSO) algorithms have been developed and simulated under Matlab-simulink environment to track the Global Maximum Power Point (GMPP). The main issue in the Incremental Conductance is, struck with the Local Maximum Point (LMP) and it fails to track the GMPP. The simulated results show that the evolutionary technique based PSO MPPT overcomes the drawbacks of I&C algorithm where it tracks the GMPP effectively. The parameters of the PV module have been obtained from the manufacturer datasheet (MS24250) for these analyses.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"9 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89792385","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}
