This overall space is called the active space and is obtained with vector representations of all valid switching states (SS) of the converter that has to be modulated. The vector representations of all valid SS are obtained from the Clarke transformation of terminal voltages obtained at ac terminals of the converter for respective switching states. In this paper simple alternative method has been presented to find α, β & γ components for a given SS. It can produce exactly same results as those computed by Clarke transformation. Application of the proposed formula does not need prior knowledge of Clarke transformation or converter's ac terminal voltages for different switching states.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117248064","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 islanding mode the inverter droop control should maintain voltage and frequency stability.

But the performance of the PRSA technique largely depends on the choice of window length (WL). It is required to optimize WL for better detection of precise but important periods present in signal. In this paper a method to optimize the window length is proposed based on the spectral analysis of original and PRSA signal. The proposed method is applied on ECG signal to characterize and classify the atrial fibrillation (AF), atrial flatter (AFL) and ventricular flutter (VFL) rhythms with statistical features. Classification of the fibrillatory episode is done by K-nearest-neighbor (KNN) and support vector machine (SVM) clustering method with derived features. Extracted features are clustered with a new approach of Root Mean Square (RMS) Technique. This algorithm is applied on to the MIT-BIH arrhythmia database and checks the performance. Both quantitative and qualitative analysis is made and sensitivity and specificity 98.24% and 96.08% respectively is achieved.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124940096","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 predecessor of Trilateral filtering, the bilateral filter is a non-linear filtering technique that can reduce noise from an image while preserving the strong and sharp edges, but it cannot provide desired result when the edges have valley or ridge like features. The Trilateral filter is extended to be a gradient-preserving filter, including the local image gradient (signal plane) into the filtering process. This filter has the added benefit that it requires only one user-set parameter (neighborhood size used for bilateral gradient smoothing), and the rest are self-tuning to the image. In this paper, we introduce an extended version of Trilateral filtering where domain and range filtering are applied on the image separately followed by applying the original Trilateral filter on the image that is produced by combination of domain and range filtered outputs. This extended approach gives better noise reduction than the original Trilateral approach and improves the image quality. We also provide an efficient Field Programmable Gate Array (FPGA) based implementation of the proposed Extended Trilateral filter(ETF) on a hardware software co-simulation environment to validate the design.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121214790","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}

Novelty of the paper lies in the fact that it considers the both frequency and spatial domain (location in time) features of EEG signal without sacrificing accuracy and very low execution time makes it feasible for real time application.

Therefore it is a stimulating task to identify a small subset of relevant genes from microarray gene expression data where the identified genes can solely be used for accurately classifying the cancer subgroups. Therefore, in this paper a computationally efficient but accurate gene identification technique has been proposed. At the onset the t-test method has been utilized to reduce the dimension of the dataset and then the proposed particle swarm optimization based approach has been employed to find useful genes. The proposed method has been applied on the small round blue cell tumor (SRBCT) data to classify the four subgroups specifically neuroblastoma, non-Hodgkin lymphoma, rhabdomyosarcoma and Ewing sarcoma. The results demonstrate that the proposed technique could identify only fourteen genes that can be efficiently exploited for the diagnostic prediction task with high accuracy.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128794248","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 presents a new method called Bias Estimated Spatial Fuzzy C-means (BESFCM) algorithm for intensity inhomogeneity estimation and segmentation of MRI images at the same time. First, we formulate a new local fuzzy membership function that includes a probability function of a pixel considering its spatial neighbourhood information. Then, we introduce a new clustering center and weighted joint membership functions using the local and global membership values. Finally, MRI images are segmented and bias field is estimated by formulating an objective function using the new cluster centers and joint membership functions. The simulation results show that the resulting BESFCM algorithm estimates intensity inhomogeneity and improves the segmentation results as compared to other FCM-based clustering algorithms.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"11220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122931887","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}
