The DC-DC topologies used for this purpose include switched capacitor(SC), switched inductor(SI) and Hybrid (SC/SL). But the above mentioned topologies have their own disadvantages as well. Switched capacitor type converters require more number of switches whereas transformer less hybrid structures demands more number of passive elements. Besides, all the above mentioned DC-DC converter circuits cannot provide an effective path for negative to positive voltage conversion with respect to a common ground. Therefore, a new DC-DC topology is to be developed to meet the same problem. Voltage lift technique is used in a DC-DC Cuk converter such that negative to positive voltage conversion with respect to a common ground is achieved. This topology is also having the added advantage of a cuk converter that both input as well as output currents are ripple free. It is also having a high boost voltage ratio of 1/(1-D), equal to that of a boost converter, where, D is the duty ratio.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132718671","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}

Shape Memory Alloys (SMA) are a potential choice in such systems. Large deflection systems are designed using SMA helical springs. Temperature induced phase transformation causes the strain in such systems. In bio mimicking and bio inspired designs, SMA's are often considered as an equivalent to an artificial muscle. Such systems require sub millimeter diameter SMA helical spring actuators working independently or in recruitment. The small physical size of actuator arises practical issues in measuring the temperature over sub millimeter helical springs. This paper introduces a sensorless temperature estimation method for SMA helical actuators and introduces simple mechanism using SMA sub millimeter helical actuator.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134072505","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}

These devices are found to be superior to silicon because of their ability to be operated at high frequency, high temperature and high voltage with reduced switching losses. In this paper a comparison between Silicon and Silicon carbide semiconductor materials are done with the help of LTSpice software by considering DC-DC Buck Boost converter topology. It can be seen that the efficiency of the converter significantly increases when SiC switches are used for switching. With the use of SiC it is possible to increase the switching frequency which will considerably reduce the size of the filters making converter compact. At present, the only challenge faced by wide band gap device industry is its cost since the technology is not yet mature enough to make it easily available.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132811261","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}

But data generated by AMI systems are now grow to the level of big data by connecting millions of consumers to the smart grid. If high speed data processing techniques are applied then system response time to detect events will be reduced and hence time taken to plan and execute action can be shortened. This will directly improve the performance indices of smart grid. This paper reveals the potential of stream computing applied to AMI data processing to detect outages. Faster detection of outages leads to faster initiation of outage restoration actions.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115157521","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 features very innovative new air interface technologies such as Orthogonal Frequency division multiplexing (OFDM), Multiple Input Multiple Output (MIMO) antenna technology and fastest link adaptations. All these components that put together will achieve remarkable performance for mobile communications. LTE has been accepted as the basis of fourth generation (4G) wireless technology and it seems that the components included here are so viable, it has staying power even 5G technologies in the future and beyond. The underlying transmission technologies and physical layer model of LTE has deep mathematical roots. Considering the dynamic nature of the transceiver system, such fast responding LTE is best understood through simulations and Matlab is the best tool to do the same. In this paper a 2×2 MIMO OFDM transceiver system with MMSE channel equalization has been setup and its performance is evaluated with and without link adaptation. Results illustrate that the proposed adaptation gives considerable improvement in data rate of the transceiver system without compromising much on the bit error rate.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124591853","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}

Many denoising techniques have been proposed for the removal of noises from a digital signal. Wavelet denoising using threshold algorithm is a powerful method for suppressing noise in digital signals. In this paper, an audio denoising technique based on double-density dual-tree discrete wavelet transform (DDDTWT) using a level dependent threshold algorithm is implemented. Audio signal contaminated with Additive White Gaussian Noise is chosen for the implementation. The results in terms of signal to noise ratio (SNR) and root mean square error (RMSE) are compared with the values of dual-tree discrete wavelet transform (DTDWT) and double-density discrete wavelet transform (DDDWT) methods and also with global thresholding method. The results of MATLAB simulations show that the proposed method is more effective and gives better performance for denoising audio signals in terms of both SNR and RMSE.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131532887","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}
