In the last energy decades energy obtained from external sources such as thermal energy, solar power, wind energy, and RF energy has been in use for various purposes. To provide unlimited energy for the lifespan of electronic devices, energy harvesting uses inexhaustible sources with no adverse environmental effect. This paper focuses on RF energy harvesting. The receiving antenna captures the RF energy from surrounding sources, such as nearby mobile phones, wireless LANs (WLANs), FM/AM radio signals, broadcast television signals and rectified into a usable DC voltage. One possibility to overcome their power limitations is to extract (harvest) energy from the environment to either recharge a battery, or even to directly power the electronic device. To meet various objectives in last few years, several antenna designs of rectenna have been proposed for use in RF energy harvesting,. Among the other antennas, microstrip patch antennas are widely used because of their low profile, light weight, and planar structure. This paper presents several methods to design and energy harvesting device depending on the type of energy available and also presents microstrip path structural rectenna are explains RF signal harvester for powering low consumption electrical devices.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125466562","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 Kinect sensor along with Software Development Kit (SDK) generates the human skeleton represented by 3-dimensional coordinates corresponding to twenty body joints. Using the co-ordinates of eleven such joints from the upper body and the hands, a set of nine features based on the distances, accelerations and angles between the different joints have been extracted. These features are able to uniquely identify gestures corresponding to five basic human emotional states, namely, `Anger', `Fear', `Happiness', `Sadness' and `Relaxation'. The goal of the proposed system is to classify an emotion based on body gesture. A comparison of classification using binary decision tree, ensemble decision tree, k-nearest neighbour, support vector machine with radial basis function kernel and neural network classifier based on back-propagation learning is made, in terms of average classification accuracy and computation time. A high overall recognition rate of 90.83% is obtained from the ensemble decision tree.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125715676","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 widely used in video surveillance, robotics, human machine interaction and other applications. The automated object detection and tracking is still a challenging task that needs to be addressed. Hence the main idea is to develop a system based on various image processing techniques to reliably detect and track people in video sequence from stationary cameras. The proposed method can be viewed as consisting of two stages namely detection and tracking. In detection stage, Histogram of Oriented Gradients popularly known as HOG is used as a feature descriptor. HOG features are robust to local changes in geometry and illumination but it is computationally expensive. This disadvantage of HOG is due to its exhaustive scanning approach over entire region of interest. The main contribution of this paper is to reduce the computational time of HOG by dynamically determining the region of interest and limiting the scan area. Further Principal component analysis is used to reduce the dimensionality of HOG features. The additional use of optical flow based tracking eliminates the need of HOG computation in every frame. Hence the person detected by HOG in initial frame is successfully tracked in subsequent frames and reduces HOG computation time. The proposed dynamic ROI selection method not only reduces detection time but also reduces the number of false positives and increases the efficiency. The experimental results show that the system efficiently detects and tracks people in videos without much of occlusion.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127722959","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}

Previously data delivery failures constantly occur in wireless applications due to node movements. The conventional route reconstruction method is designed to mitigate the effects of topology change, but it utilizes a large amount of resources. In this prototype we construct the regularity in node mobility patterns and ensure that transmission of data between the nodes is efficient. The positions of the routers are designed and tree topology is constructed so that all nodes movements are directed towards the root of the tree. First deploy the nodes in a network then calculate the maximum in degree node to find out coordinator node and finally construct the tree in order to send the data to the destination. Implement the capacity calculation if in- degree node numbers are the same in any two nodes. Further the best node is calculated if the capacity of both the nodes is same and node trustworthiness is calculated using the recommendation system.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126065566","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 wireless systems that is evolved the last few decades necessitates in the design and analysis of equalization techniques. The current trend as well as the future generation of wireless systems is supposed to possess very high spectral efficiency, presence of rapidly time varying channels due to high mobility and the availability of partial or no channel state information at the transmitter and/or receiver which prescribes MIMO systems. When the data is transmitted at high bit rates, over mobile radio channels, the channel impulse response can extend over many symbol periods, which lead to Inter-symbol interference (ISI).
