Audio and visual signals, being the primary modalities of human emotion perception, have attained the most attention in developing intelligent systems for natural interaction. The emotion recognition system must automatically identify the human emotional states from his or her voice and facial image, unaffected by all possible constraints. In this work, an audio-visual emotion recognition system has been developed that uses fusion of both the modalities at the decision level. At first, separate emotion recognition systems that use speech and facial expressions were developed and tested separately. The speech emotion recognition system was tested on two standard speech emotion databases: Berlin EMODB database and Assamese database. The efficiency of visual emotion recognition system was analyzed using the eNTREFACE'05 database. Then a decision rule was set for fusion of both audio and visual information at the decision level to identify emotions. The proposed multi-modal system has been tested on the same eNTERFACE'05 database.","PeriodicalId":403350,"journal":{"name":"2016 IEEE Students’ Technology Symposium (TechSym)","volume":"C-22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126787623","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}

Most of the image encryption algorithms will generate encrypted images with noise-like or texture-like contents. Hence it's easy to distinguish natural images from encrypted images. The chances of attacks and image analysis by malicious people are more on images with noise-like or texture-like contents. This paper presents an efficient visually meaningful image encryption algorithm that uses integer discrete wavelet transform(DWT) and Arnold transform. The central idea of proposed scheme is to use a reference image to hide the original image in its encrypted form. Arnold transform has been used to transform the encrypted original image content before inserting it into the wavelet sub-bands of the reference image. The final encrypted image will look similar to the reference image, and the original image can be extracted and decrypted by an authorized person who has the valid decryption and data hiding key.","PeriodicalId":403350,"journal":{"name":"2016 IEEE Students’ Technology Symposium (TechSym)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115423907","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 concept is validated with parametric variations of several important EBG parameters. The design confirms the luxury to obtain pass-band at other microwave bands by simple alterations of the dimensions of the inverted F shaped EBG elements.

It provides network and upper layer services for LR-WPAN, cyber physical systems, industrial sensor networks, smart grids, home automations, etc. The routing layer uses the tree based routing protocol wherein only parent-child relationship are considered for routing, ignoring neighbor nodes. This results in packets being routed through several hops towards the destination even if it is within senders 1-hop transmission range, via highly loaded or high traffic links. The paper proposes an improved ZigBee algorithm by employing neighbor tables and link quality indicator (LQI). Keeping in mind the low complexity of traditional ZigBee protocol, priority based approach has been implemented by using two reserved bits as priority bits in route selection. Opnet Simulator is used for the simulation purpose along with Visual Studio 2005 for C++ compiler. From the simulation results it can be observed that the proposed priority based routing protocol performs better than the classical ZigBee tree algorithm, and thus can be claimed as an enhanced ZigBee protocol.","PeriodicalId":403350,"journal":{"name":"2016 IEEE Students’ Technology Symposium (TechSym)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115780970","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}

Hence, Energy Harvesting domain becomes center of attraction of worldwide researchers. It is possible to harvest the energy from the ambient sources which are freely available in surrounding and use this harvested energy to power the miniaturized devices which require microwatt power. Since, human body parts like finger, brachial, ankle are curved in nature thus flexible harvester is proposed in order to mesh with human body parts. Human motions are often complicated and a periodic. Capturing the vibrations and harvesting the energy from those vibrations is the need of hour. The proposed harvester with copper meshed electrodes and Zinc oxide (ZnO) as piezoelectric material was fabricated by simple and inexpensive spin coating method. Copper has been the material of choice for electrodes because of its exceptional electrical conductivity and availability. The measured electric potential of the proposed harvester was 0.65 volts at a resonance frequency of 41 Hz and array is proposed for more electric potential and power.","PeriodicalId":403350,"journal":{"name":"2016 IEEE Students’ Technology Symposium (TechSym)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131542520","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 modification is done in the initialization method and is called the two stage initialization (TSI). In TSI, the population vector generation is done randomly in two stages. Then the newly generated population vector from TSI would go through the rest of the phases involved in the algorithms. Further, these two stage initialized optimization algorithms and their original versions are used to tune the PID controller for automatic voltage regulator (AVR) system. Comparison of the results so obtained due to the application of six optimization algorithms out of which three are already existing ones and the other three are their TSI versions to PID-AVR system is also done. It can be realized that TSI helps the existing algorithms to have greater convergence rate and also to converge at a lesser minimum value of the objective function.","PeriodicalId":403350,"journal":{"name":"2016 IEEE Students’ Technology Symposium (TechSym)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125087167","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}
