The proposed database is recorded using professional artists from Gyanavani FM radio station, Varanasi, India. The speech corpus is collected by simulating eight different emotions using neutral (emotion free) text prompts. The emotions present in the database are anger, disgust, fear, happy, neutral, sad, sarcastic and surprise. This speech corpus is named as Indian Institute of Technology Kharagpur Simulated Emotion Hindi Speech Corpus (IITKGP-SEHSC). Emotion classification is performed on the proposed IITKGP-SEHSC using prosodic and spectral features. Mel frequency cepstral coefficients (MFCCs) are used to represent spectral information. Energy, pitch and duration are used to represent prosody information. The average emotion recognition performance using prosodic and spectral features are found to be around 77% and 81% for female speech utterances. This paper describes the design, acquisition, post processing and evaluation of the proposed speech corpus (IITKGP-SEHSC). The quality of the emotions expressed in the database is evaluated using subjective listening tests. The emotion recognition performance using subjective listening tests is observed to be around 74%. The results of subjective listening tests are grossly on par with the results obtained using prosodic analysis of the database.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133549162","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, a novel closed form delay metric has been proposed for the on-chip VLSI RLC interconnect. The model has also been extended for the case when the time of flight of the input signal is comparable. It is started with a distributed RLC line model of the interconnect and analytically solved the resulting diffusion equation for the voltage response and 50% delay has been calculated and has been compared with SPICE delay and error is within 7%. The proposed method also calculates 50% delay by taking the time of flight into consideration and result is compared with SPICE and the average error has been found to be within 6%.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134257631","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 with the help of an energy chip, an improved energy metering solution is developed, where automating the progression of measurement through digital wireless communication technique is adopted to get the above benefits alongwith smooth control. The developed energy meter calculates the total average active power mainly for residential consumers. The hardware circuit accepts single phase voltage and currents as its inputs and provides the output in the form of logic data proportional to the average real power. This data is fed to a remote computer server through the wireless ZigBee network that represents the concept of distant wireless metering, practically involving no manpower. This paper also presents a software solution developed for total electrical energy billing and data management system.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127939309","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 is identified as the key requirement and is one of the most challenging issues in cognitive radio system. In this paper, a hybrid model for transmitter based spectrum sensing have been presented, in which various aspects of spectrum sensing problem under transmitter based detection are studied with a cognitive radio perspective. In this hybrid terminology, proper channelization of the three techniques (matched filter detection, energy detection and cyclostationary feature detection) have been performed with relevant discussion. The presented approach helps in detecting the idle spectrum bands (spectrum holes that is the underutilized sub bands of the radio spectrum) opportunistically with better utilization of the spectrum under non cooperative sensing with increase in the overall spectrum efficiency.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128566316","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 piecewise linearization of individual functions provide a platform for the piecewise affine approximation of nonlinear systems containing a large number of scaler valued nonlinear functions. Inspite of the wide application of piecewise linearization, the optimal approximation of a continuous time nonlinear function by the minimum number of piecewise linearised functions has not been addressed properly in literature. This paper deals with an evolutionary optimization based clustering approach for obtaining the optimal piecewise linear approximation of a class of nonlinear functions. The technique is based on the trade-off between increasing the approximation accuracy and simplifying the approximation by the minimum number of linearized sectors. The technique has been successfully applied to some common nonlinear functions.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129457972","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}
