This media knowledge helps people, company and organizations to analyze information for important decision making. Opinion mining is also called as sentiment analysis which involves in building a system to gather and examine opinions about the product made in reviews or tweets, comments, blog posts on the web. Sentiment is classified automatically for important applications such as opinion mining and summarization. To make valuable decisions in marketing analysis where implement sentiment classification efficiently. Reviews contain sentiment which is expressed in a different way in different domains and it is costly to annotate data for each new domain. The analysis of online customer reviews in which firms cannot discover what exactly people liked and did not like in document-level and sentence-level opinion mining. So, now opinion mining ongoing research is in phrase-level opinion mining. It performs finer-grained analysis and directly looks at the opinion in online reviews. The proposed system is based on phrase-level to examine customer reviews. Phrase-level opinion mining is also well-known as aspect based opinion mining. It is used to extract most important aspects of an item and to predict the orientation of each aspect from the item reviews. The projected system implements aspect extraction using frequent itemset mining in customer product reviews and mining opinions whether it is positive or negative opinion. It identifies sentiment orientation of each aspect by supervised learning algorithms in customer reviews.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127770082","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 focus on generation of nano/micro feature size patterns using four-beam interference lithography technique. The generated periodic array pattern structures are developed using MATLAB. The interference parameters in FBIL include wavelength (λ), slit separation (d), angle of incidence (Θ), distance between slit and screen (L) and depth of penetration (DOP). We have simulated and modelled the four beam interference lithography technique by varying interference parameters to produce various feature size patterns over the surface of the substrate. The obtained pattern structures have the periodicity of 0.75 μm for 1064 nm, 0.39 μm for 565 nm. Depth of the focus is found to be 0.235 μm for 1064 nm and 0.125μm for 565 nm. Highest value of depth of penetration is observed to be 0.552 mm and 0.586 mm for 1064 nm and 565 nm respectively. The study of FBIL shows depth of penetration increases with decrease in slit separation. More complex patterns can also be produced on varying the position of beams, angle of incidence and number of beams. FBIL can be applied in fabrication of 3D photonic crystals, magnetic storage, solar cells, waveguides, calibration grids, OLEDs and functional surfaces of sensors.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134070188","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 the combination of static compensator (STATCOM) and static synchronous series compensator (SSSC). The control theory is based on vector control- dq(direct quadrature axis) reference frame fed PI, hysteresis control and fuzzy logic control using DSOGI-PLL(Dual second order generalized integrator- Phase locked loop). The proposed system is implemented using MATLAB / SIMULINK platform with and without Unified power flow controller. The effect of UPFC for fixed speed windturbine under faults is analysed using the above three controllers and its performance is evaluated.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115432385","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}

For this purpose, development of Intelligent Transportation Systems (ITS) technologies that contribute to improved traffic flow stability, throughput, better utilization of infrastructure and safety is needed. In today's traffic, to achieve the safe inter-vehicle distance, avoid congestion and improve safety, the limited human perception of traffic conditions and human reaction characteristics constrain should be analysed. In addition, erroneous human driving conditions may generate shockwaves in addition which causes traffic flow instabilities. In this paper to achieve regulated inter-vehicle distance and improved throughput, we consider Cooperative Adaptive Cruise Control (CACC) system, for vehicle string. Information of individual vehicle is exchange between vehicles through wireless communication in addition can give better performance. By introducing vehicle to vehicle (V2V) and vehicle to roadside unit (V2R) communications, the vehicle gets information not only from its preceding and following vehicle but also from the vehicles in front of the preceding one and following one.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124848450","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}
