The device is much similar to the conventional white cane in appearance and it is fabricated using ultrasonic sensors, a vibrator motor scheme, a controller and a power unit inside the walking stick. The sensor system comprises of three ultrasonic sensors to acquire obstacle distance measurements and the user can interpret the distance information as a tactile sensation. The sonar sensors are fired with a sequential firing mechanism to avoid crosstalk. Distance is felt by the user in terms of the vibration intensity change. This device was tested with blind school students and results are presented.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131369393","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}

Epileptic seizures are due to hyperactivity in certain parts of the brain. Automatic seizure detection helps in diagnosis and monitoring of epilepsy especially during long term recordings of EEG. This paper presents the bispectrum analysis of electroencephalogram (EEG) for the detection of epilepsy. Bispectrum is a higher order spectrum. It characterizes the nonlinearities in the signal. Features extracted from the bispectrum of EEG are applied to the neural network classifier to detect normal and epileptic EEGs. The classification accuracy of 81.67% is obtained. The results demonstrate that the proposed features are more effective in differentiating epileptic EEG as compared to features from the conventional power spectrum.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"432 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122872083","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 classical HVDC system and VSC-HVDC system showed greater advantages in power transmission and industry. Meanwhile major disadvantages like commutation failure, reactive power requirement in classical system and high cost, high switching losses and inability to handle DC line fault in VSC-HVDC system lead to the invention of LCC-VSC hybrid HVDC system. With no commutation failure, less reactive power requirement and reduced losses, the hybrid system is best suited for unidirectional power transmission scenarios, such as power transmission to islands and remote load centers, where the construction of new transmission lines is prohibitively expensive. The present work aims to study various aspects of hybrid HVDC system. The emphasis will be on developing appropriate control schemes at both rectifier and inverter terminals for efficient operation of the hybrid system and achieve best performance of the system under steady state and transient condition. The simulation study is carried in the PSCAD/EMTDC environment.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127053602","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}

CB-CPW is different from conventional CPW in a sense that it has an additional ground at the bottom surface of the substrate material. This bottom ground plane not only offers mechanical support to the substrate but also works as a heat sink for circuits with active devices. The antenna is designed on a flame retardant woven glass reinforced epoxy resin (FR4) substrate material. The proposed design has reduced total area by 55 percentage with respect to the previous similar antenna. The antenna parameters such as 2D radiation patterns, gain, VSWR, return loss, and antenna efficiency are obtained and all of them meet acceptable standards of basic antenna. Numerical simulations are carried out using IE3D software based on Method of Moment (MoM) technique.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123362316","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}

WSN has great deal of applications in various fields like military, agriculture, industry healthcare etc. Sensor nodes are randomly and densely deployed. This kind of deployment creates large number of redundant sensor data. Routing of such redundant data not only saturates network resources, but also consumes more energy. Data aggregation is the effective technique which reduces the number of transmissions to sink node by aggregating the similar packets in an energy efficient manner to enhance the lifetime of network. There exists different data aggregation techniques which perform aggregation in single level or two levels. In this paper we are proposing multilevel hierarchical data aggregation technique which handles the redundancy in sensor data very efficiently.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121503610","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, most of the traditional methods employed for this purpose suffer from certain limitations in accomplishing this task. A successful implementation of condition monitoring requires the development of a simple but reliable detector of various faults. This paper investigates the performance of Discrete Wavelet Transform and Radial Basis Function based Neural Network for incipient stator fault diagnosis in induction motors. Wavelet analysis helps in the extraction of important features from the faulty signal and neural network classifies the fault type depending on the nature of fault. A mean absolute percentage error of 1.4236% between the actual values and the predicted values by the neural network show the effectiveness of the proposed approach.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122079686","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}
