We propose a new approach for moving object detection. Moving object detection is low-level, important task for any visual surveillance system. The aim of this paper is to, to describe traditional approach of moving object detection techniques such as background subtraction, temporal difference, as well as pros and cons of these techniques. Finally, we propose the statistical mean technique to overcome the problem in traditional techniques. Since, simple statistical mean technique having disadvantages, to defeat those, we propose incremental statistical mean technique. Incremental statistical mean technique have need of computation to perform simultaneously, that requires parallel computation to speed up and reduce the computation complexity. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2012.

In this paper, the net irrigation water requirement estimation is carried out for different crops in Limbasi branch canal command area of Mahi Right Bank Canal (MRBC) project located in Gujarat, India. The Hargreaves – Samani approach for reference crop evapotranspiration (ETo) estimation is used for thirteen years of available data and the mean monthly ETo values were computed which were analyzed statistically. The potential crop evapotranspiration (ETc) and net irrigation requirement (NIR) of different crops in kharif, rabi and summer season were estimated. Results show that the NIR values (mm) for kharif crop paddy was 166.8; rabi crops jowar, tobacco & wheat were 404.3, 504.2 & 564.7 and summer crops paddy & bajri were 851.1 & 619mm respectively. © 2015 Association of Agrometeorologists.

International Review on Modelling and Simulations | Year: 2011

Conventional Transmission and Distribution systems do not envisage at present any generation on consumer side. However, with the enactment of Indian Electricity Act 2003 and due to the major changes in the Power Sector and the fast move towards liberalization of the energy markets, utilities are inclined to install small capacity generating units to distribution systems. Integration of small capacity generators at load points in the existing electrical network will have impact on voltage regulation, losses, reserve capacity of network etc. In this paper, Renewable Distributed Generators (RDGs) are introduced at a suitable location of a heavily loaded distribution network to minimize distribution losses. Case study has been performed on a real 3.4 MVA distribution system of a particular area of Gujarat state. A methodology has been developed for citing the RDGs at a suitable location in the Network. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.

This paper analyzes the impact of Renewable Distributed Generation on a 4.02 MVA Radial Distribution Network of a particular area of Gujarat state, India. Distribution System software simulation of existing Network revealed severe voltage regulation problems in major portion of the Network, overloading of few sections and high losses. A methodology has been developed and presented in this paper for determining appropriate locations for integration of Renewable Distributed Generators within the Distribution Network with the objective of improving voltage profile and reduction in losses. After the integration of Renewable Distributed Generation in the Network as per the methodology developed, the simulation results reveal that the minimum voltage in the Network is within the permissible regulatory limits and significant loss reduction is achieved. Also an advantage is increased Network reserve capacity to cater additional load with the same existing Network. © 2012 IEEE.

The major issues always attached to conventional electrical Distribution Systems are poor voltage regulation so far the consumers are concerned and the high level of losses & limited or no reserve capacity of the Network so far as the utility is concerned. In this paper, an attempt has been made to address both issues by adding Dispersed Generation of appropriate capacity at appropriate location, using a methodology developed and described here. The study on a 2.8 MVA Radial Distribution Network having low voltage problem and high losses has been conducted and the results are found encouraging. For this purpose, the Network was simulated for obtaining existing status of voltage profile and losses and thereafter similar study was carried out by adding Renewable Distributed Generation. The analyses of results clearly show that there is no low voltage problem in any section of the Network, with a considerable reduction in losses. Incidentally, the reserve capacity of the Network is also increased giving a scope for future expansion. © 2012 IEEE.
