This paper suggests a novel approach to support the communication and interaction of deaf- blind individuals, thus fostering their independence. It includes a smart glove that translates the Braille alphabet, which is used almost universally by the literate deafblind population, into text and vice versa, and communicates the message via SMS to a remote contact. It enables user to convey simple messages by capacitive touch sensors as input sensors placed on the palmer side of the glove and converted to text by the PC/mobile phone. The wearer can perceive and interpret incoming messages by tactile feedback patterns of mini vibrational motors on the dorsal side of the glove. The successful implementation of real-time two- way translation between English and Braille, and communication of the wearable device with a mobile phone/PC opens up new opportunities of information exchange which were hitherto un-available to deafblind individuals, such as remote communication, as well as parallel one-to many broadcast. The glove also makes communicating with laypersons without knowledge of Braille possible, without the need for trained interpreters.","PeriodicalId":442000,"journal":{"name":"2015 International Conference on Pervasive Computing (ICPC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117188956","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}

Conventional Tandem motion uses the high speed DC motor; where it is problematic to vary the speed of the wiper arms. Also there are weight and space constraints. In proposed system a pair of synchronized windshield wipers is used, in which each wiper arm is driven by its own independent motor. Traditional rigid mechanical linkages, driven by a single DC motor are removed for the sake of weight and space. For synchronisation and to avoid collision a closed loop control system is used. By Synchronising Two DC Motors, which are controlled using Peripheral Interface Controller (PIC) or Field Programmable Gate Array (FPGA), problems regarding Weight and Space can be solved. At present, synchronisation is achieved using Digital Signal Processor (DSP). As Cost of DSP is more, it is proposed to implement design using PIC. Also to get more design flexibility, system is implemented using FPGA. The results, which are going to obtain with PIC or FPGA, have to compare with the results that have obtained with existing method of Synchronisation by using DSP.","PeriodicalId":442000,"journal":{"name":"2015 International Conference on Pervasive Computing (ICPC)","volume":"14 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131491736","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 requires operation of the network closer to their stability limits. This leads to compensated transmission lines. Installing capacitors of fixed or controllable value provides a viable solution to improve power system stability and also to optimize power flow transmission capability of electrical grids transmission capability of power grid, optimize power flow and to improve system stability. However, installations of capacitors results into changing directions and values of fault currents and voltages in the networks. It causes problems for protective relays and fault locators. Distance relay is prone to maloperate due to large variations in voltage and current. Since fault location and classification are important tasks to safe guard electric power systems, as per the literature survey various practical or theoretical schemes are used to attain the reliable protection system for transmission lines equipped with compensation capacitors. This paper highlights merits and demerits of different methodologies to enhance distance protection of compensated transmission lines.","PeriodicalId":442000,"journal":{"name":"2015 International Conference on Pervasive Computing (ICPC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134348011","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}

In this hiding technique secret information or message is concealed into other innocent data such as text, audio, image etc. The main objective of Steganography is to preserve covert communication among two parties. Steganography plays crucial role in various applications like modern printers, intellectual property rights, network security. Also it is used by intelligence services. As color image requires large hiding capacity, most of the existing steganography schemes are proposed for gray images. To improve hiding capacity in addition to having minimum alterations to host image, the paper propose a technique of hiding secret color image into cover image with same size as secret image. In the proposed method vector quantization (VQ)is applied to secret color image to get compressed data and that compressed data is concealed into host color image using Least Significant Bit (LSB) replacement technique. Experiment was conducted on 15 secret images, each one embedded into 15 cover images. Experimentation carried out using three different VQ methods, like Linde-Buzo-Gray(LBG), TCEVR (Thepade's Cosine Error Vector Rotation) and KFCG (Kekre's Fast Codebook Generation). Experiment shows KFCG performs better followed by TCEVR over conventional method like LBG. In all VQ methods high cluster size gives better quality of reconstructed secret.","PeriodicalId":442000,"journal":{"name":"2015 International Conference on Pervasive Computing (ICPC)","volume":"452 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134414344","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 very important to hide the secret data efficiently, as many attacks made on the data communication. The host signal can be a still image, speech or video and the message signal that is hidden in the host signal can be a text, image or an audio signal. The cryptography concept is used for locking the secret message in the cover file. The cryptography makes the secret message not understood unless the decryption key is available. It is related with constructing and analyzing various methods that overcome the influence of third parties. Modern cryptography works on the disciplines like mathematics, computer science and electrical engineering. In this paper a symmetric key is developed which consists of reshuffling and secret arrangement of secret signal data bits in cover signal data bits. In this paper the authors have performed the encryption process on secret speech signal data bits-level to achieve greater strength of encryption which is hidden inside the cover image. The encryption algorithm applied with embedding method is the robust secure method for data hiding.","PeriodicalId":442000,"journal":{"name":"2015 International Conference on Pervasive Computing (ICPC)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128757920","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 presents comparison of twelve assorted similarity measures for image compression using Kekre's Error Vector Rotation (KEVR) and Thepade's Cosine Error Vector Rotation (TCEVR)code book generation algorithm. The codebook of four different sizes 128, 256, 512 and 1024 are generated for 20 images using 12 different similarity measures. These similarity measures are chosen from five different families such as Minkowski, L1, Squared L2, Intersection and Fidelity. The images are reconstructed from respective codebooks and compared with original image with respect to Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The results have shown that similarity measures belonging to SquaredL2and Fidelity family such as Squared, Euclidean and Square-Chord give lower MSE and higher PSNR values as compared to others. The TCEVR gives better compression over KEVR for all similarity measures except Fidelity family.","PeriodicalId":442000,"journal":{"name":"2015 International Conference on Pervasive Computing (ICPC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129231821","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}
