http://ijaems.com/ Open Access international Journal to publish research paper en-us October 2015 Matrix converter is a direct AC-AC converter topology that directly converts energy from an AC source to an AC load without the need of a bulky and limited lifetime energy storage element. Due to the significant advantages offered by matrix converter, such as adjustable power factor, capability of regeneration and high quality sinusoidal input/output waveforms. Matrix converter has been one of the AC–AC topologies that hasreceived extensive research attention for being an alternative to replace traditional AC-DC-AC converters in the variable voltage and variable frequency AC drive applications. In the present paper an indirect space vector modulated matrix converter is proposed. The basic idea of an indirect modulation scheme is to separately apply SVM to the rectification and inversion stages, before combining their switching states to produce the final gating signals. The paper encompasses development of a laboratory prototype of 230V, 250VA three phase to three phase DSP controlled matrix converter fed induction motor drive. The observations and real time testings have been carried out to evaluate and improve the stability of system under various typical abnormal input voltage conditions http://ijaems.com/detail/design-and-development-of-novel-matrix-converter-performance-enhancement-technique-for-induction-motor-drive/ Suriti Gupta1, K.C.

The access to safe water in India has commendably improved from 72% in 1990 to 94% in 2014. Delay in providing facilities to counterbalance the population growth and water demand is the major problem in India. Water loss in water distribution systems in an important issue in India. Studies indicate that up to 50-60 percent of treated and pumped water in lost during transit form water treatment plant to consumer end. It has, therefore, attracted a lot of attention of practioners and the researchers as well over the past few years. High levels of non-revenue water (NRW) reflect huge volumes of water lost through physical and apparent loss components, not being invoiced to customers. It seriously affects the financial viability of water utilities through lost revenue and increased costs. The overall objective of a distribution system is to deliver wholesome water to consumers at adequate residual pressure in sufficient quantity and achieve continuity and maximum coverage by reducing losses. A case study of 4-pilot sites of Jaipur city was taken for NRW study. This paper provides a review of the issues and strategy pertaining to reduction of NRW with special reference to India and the necessity of evolving appropriate performance indicator http://ijaems.com/detail/capacity-building-program-for-non-revenue-water-reduction-techniques-in-india/ Shubham Shah http://ijaems.com/upload_images/issue_files/1452744621-2 IJAEMS-OCT-2015-5-Capacity Building Program for Non-Revenue Water Reduction Techniques in India .pdf In Vehicular Ad hoc NETworks (VANETs), vehicles have to be protected from the misuse of their private data and the attacks on their privacy. Here the authentication issues with privacy preservation and non-repudiation in VANETs have been considered. The self-generated public-key cryptography PKC based pseudonyms are also used as identifiers instead of vehicle IDs for the privacy-preserving authentication, while the update of the pseudonyms depends on vehicular demands. The existing ID-based signature (IBS) scheme and the ID-based online/offline signature (IBOOS) scheme are used, for the authentication between the road side units (RSUs) and vehicles, and the authentication among vehicles, respectively. Authentication, privacy preservation, non-repudiation have been analyzed for VANETs. Typical performance evaluation has been conducted using efficient IBS and IBOOS schemes. http://ijaems.com/detail/improving-privacy-preservation-using-ibs-and-iboos-in-vanet/ J.Lavanya, Dr. S.

Key-aggregate cryptosystem produce constant size cipher text . That is very efficient delegation rights of decryption for any set of cipher text are possible. Any set of secret keys can be aggregated and make them as single key, which groups all the key by making it a aggregate key. This aggregate key can be sent to the others for decryption of cipher text set and remaining .Encrypted files outside the set are remains confidential. Cloud storage could provide secured data sharing http://ijaems.com/detail/development-of-novel-encryption-for-secured-data-sharing/ T. Dhivya Bharathi, Dr. S. Sivananaithaperumal, V. S.
