The Motor must be designed in the proper dimensions only then the motor can be used for a particular application. Before manufacturing the motor, the torque and Cogging torque of the motor must be known as the cogging torque should always be less than that of net torque. If not, the motor will not freely rotate and also draws large amount of current. This paper is to obtain torque and Cogging torque values through Simulation using MAGNET Software version 7.4.1(FEM ANALYSIS). It mainly deals with the analysis of Flux distribution and Saturation (Flux density) in the core.","PeriodicalId":328137,"journal":{"name":"2014 International Conference on Green Computing Communication and Electrical Engineering (ICGCCEE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123905694","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}

However write through policy incurs large power utilization, while accessing the cache at low level (L2 cache) during write operation. In existing method, way_tagged cache was used under write-through policy, it's consumed more energy. A new cache architecture has a partial tag enhanced-bloom filter is used to improve the accuracy of cache miss prediction. By maintaining the wag tag of L2 cache in the L1 cache during read operation. The proposed technique enables L2 cache to work in direct mapping manner during write hit and reducing tag comparison of cache miss prediction, if cache miss is predicted there is no need to access the L2 cache. So that significant portion of energy will be reduced, without performance degradation. Simulation results are obtained both L1 and L2 cache configuration. The proposed technique achieves 63% energy saving in L2 cache on average with only 0.02% area overhead and no performance degradation, when compare with existing methods.","PeriodicalId":328137,"journal":{"name":"2014 International Conference on Green Computing Communication and Electrical Engineering (ICGCCEE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124177951","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}

Two main segments of CR technology are spectrum sensing and spectrum management. Sensing is related to monitoring the Licensed Users while spectrum management is related to allocating the unused licensed spectrum to Unlicensed Users effectively, without interfering with the operation of Licensed Users. In this paper we are trying to solve the spectrum management problem with the help of real time Auto Route Selection method. The real life auto route selection resembles the spectrum management issues in CR. We propose a new model for effective management of the spectrum and sharing them among the unlicensed users without any conflict with primary user. The model is utilizing the traffic pattern of PUs. The central controller combines the traffic weights with the local decisions observed through radiometer and finally decides the spectrum availability.","PeriodicalId":328137,"journal":{"name":"2014 International Conference on Green Computing Communication and Electrical Engineering (ICGCCEE)","volume":"513 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130100702","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}

Due to the high complexity in techniques such as real time processing and image contents analysis/understanding, a well-developed product is not available until now in this field. In this work, human presence is detected from an image by extracting the skin region (if present). Since human skin can be found in a varied colour, fuzzy approach is used to extract the skin region. After that individual faces are detected. Eigenface is used to recognize different faces. The experimental results show the effectiveness of the proposed technique.","PeriodicalId":328137,"journal":{"name":"2014 International Conference on Green Computing Communication and Electrical Engineering (ICGCCEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129888654","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}

As the name suggests, squaring is the main principle behind this method. The implementation results are compared with that of an ordinary Montgomery multiplier and the k - partition method in terms of power and area constraints.

Increasing size and capacity of power systems have rendered them more complex which in turn has led to reduced reliability of such systems. Power distribution systems are always prone to faults. Faults in power systems are generally due to short circuits, lightning etc. Fast and proper restorations of outages are crucial to improve system reliability. For quick and adequate recovery actions such as the determination of the propriety of carrying out forced line charging and the necessity of network switching, and an efficient patrolling, understanding the cause of a fault in an electric power system in the system operation is essential. Moreover, unknown faults may add to unnecessary costs if effective restorations and identifications can't be done quickly. So, identification of a fault on a transmission line needs to be correct and rapid. However, recognition of the causes of distribution faults accurately generally lack in expert personnel. Also the knowledge about the nature of these faults is not easily transferable from person to person. So, effective means of fault identification needs to be encouraged. In this paper, some of the unconventional approaches for condition monitoring of power systems comprising of wavelet transform, along with the application of soft computing techniques like artificial neural networks, fuzzy logic, support vector machines, genetic algorithm and hybrid combinations based on these have been studied.","PeriodicalId":328137,"journal":{"name":"2014 International Conference on Green Computing Communication and Electrical Engineering (ICGCCEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116297918","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 paradigm shift for interconnect which was once considered just parasitic but can now be a dominant factor for integrated circuit performance provided the greatest impetus for change of existing methodologies. Copper, which is presently used as the interconnect material. Cu interconnect dimensions begin to come into the range of mean free path of electron typically 40nm. This results in surface and grain boundary scattering. Owing to these scattering phenomena resistivity, of Cu begins to increase. This limitation of copper interconnects is driving research for alternative interconnect materials and technologies for next-generation ICs. Nanotubes, Graphene, and Nanowires and Carbon Nano Tubes are some of the new materials suggested as an alternate to overcome these problems.
