Visco- Elastic Plates are being increasingly used in the aeronautical and aerospace industry as well as in other fields of modern technology. To use them a good understanding of their structural and dynamical behavior is needed. In the modern technology, the plates of variable thickness are widely used in engineering applications. The present work is to develop for the use of research workers in space technology, mechanical sciences and nuclear energy where certain components of the structure have to operate under the elevated temperature. The aim of present paper is to study the bi-linearly thermal effect on vibration of visco-elastic square plate whose thickness varies parabolically in x-direction. A frequency equation is derived by using Rayleigh-Ritz technique. Two modes of frequency are calculated by the latest computational software for the various values of taper parameter and thermal gradient.

In this paper, we exam firm’s incentive to manage earnings raising external capital varies with investor beliefs. Under the spline specification regression: a firm is more likely to management earnings when investors are more optimistic about the industry prospects, but more reluctant when investor belief is low. We evaluate monitory cost to explore the reasons and find that using venture capitalists as specialized investors with lower monitoring costs than other institutional investors, earnings management is less likely for low investor beliefs but more likely for high investor beliefs for VC-backed firms relative to non-VC-backed firms. We can also obtain the same results as former study that auditor’s quality negatively related with earnings management. Considering above consequence, we documents IPOs firms engaged in managing earnings with high investor beliefs have an influence on the long-run abnormal stock return performance. These findings have implications for investors, firms, and accounting standard setters. More prudential monitory is important during market booming periods.

The need for renewable energy sources is on the rise because of the acute energy crisis in the world today. India plans to produce 20 Gigawatts of Solar power by the year 2020, whereas we have only realized less than half a Gigawatt of our potential as of March 2010. Solar energy is a vital untapped resource in a tropical country like ours. The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. To maximize a photovoltaic (PV) system's output power, continuously tracking the maximum power point (MPP) of the system is necessary. Maximum power point tracking (MPPT) is a technique that grid tie inverters, solar battery chargers and similar devices use to get the maximum possible power from one or more solar panels. Solar cells have a complex relationship between solar irradiation, temperature and total resistance that produces a non-linear output efficiency known as the I-V curve. It is the purpose of the MPPT system to sample the output of the cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions. Maximum power point tracking (MPPT) algorithms provide the theoretical means to achieve the MPP of solar panels; these algorithms can be realized in many different forms of hardware and software.

This paper presents wireless ad hoc network which communicate with each other by forming a multi-hop radio network and maintaining connectivity in a decentralized manner. The principle behind ad hoc networking is multi-hop relaying, which means that the messages are transmitted by the other nodes if the target node is not directly reachable. For communications with the nodes which are not within the radio range of nodes to the route must be taken from the intermediate nodes to reach the destination. These intermediate nodes acts as router which receives the data coming from the source and forwards the data to destination This situation is of potential security concern as there can be attack possible by the intermediate node like Man in Middle Attack. Hence an authentication procedure is be used for authenticating the mobile nodes to each other and proper encryption decryption mechanisms is also employed. Also intermediate nodes can act as malicious nodes which must be removed or alternate route should be found which does not include nodes already used in previous route. Thus we have developed architecture will provide secure routing mechanism which will use two kinds of encryption techniques. Then the possible attacks are being analyzed and removed from the architecture.

A trial was conducted during 2005 06 & 2006-06 at All India Coordinated Research Project for Dryland Agriculture Phulbani, Orissa ,India., with an objective to obtain the water loss and economics of the lined ponds .There were three treatments T1-Lined pond with soil cement plaster (6:1) 8cm thickness ,T2-Unlined pond,T-3-No pond.10% of the cropped area was dug for construction of the pond in Lined and Unlined pond treatments. The size of the pond is 7m top widths, 1m-bottom width, 3m heights, and 1:1side slope. The water harvested in pond was reutilized for the pumpkin crop, which was sown only in Lined pond treatment, as there was no water available in unlined pond so the crop was not sown there. Lined pond with soil cement (6:1) plaster of 8cm thickness gave highest Tomato yield of 4.8 t/ha during kharif 2008-09 and radish root yield of 25.5 t/ha in rabi seasons of 2008-09.. The water loss was 326 lit/day in lined pond and 24,000 lit/day in unlined pond. The benefit: cost ratio in lined pond was 3.04 as compared to 1.64 in unlined pond during 2008-09.

This paper focuses on the design of multi-element micro strip patch antenna array applicable to WLAN/MIMO at 2.4 GHz. Obviously, the performance of multi-element antenna system depends critically on the proper design of the arrays. In this paper design and simulation of 4x1 micro strip patch array with software IE3D is discussed. The performance of array have been compared with that of a single element micro strip patch antenna .Also the effect of mutual coupling of array elements on its performance is discussed .To reduce surface wave propagation, implementation of EBG substrate is discussed.

In service based systems, QoS are the basic construct that aims to facilitate the quality and usability of service based system. Service based systems takes a very long time to get the result under workload, of quality evaluation when dealing with a workflow with several thousand services and multiple parameters. To address this need, we introduce a tool-supported framework for the development and to improve the evaluation performance of QoS by optimizing the QoS requirements. OQoSE approach develops adaptable service based systems which increases the evaluation result of QoS efficiently. OQoSE method which used to review every service and parameter time then it is used to discover the probabilities that are adaptable under various services with multiple parameters.

Present study is an attempt to study the difference in academic achievement of higher secondary school students on the basis of Emotional Intelligence and its four components namely Interpersonal Skill, Intrapersonal Skill, Interpersonal Management, Intrapersonal Management. Study was conducted on one hundred sixty higher secondary school students, selected by adopting random sampling technique. Data was collected by using Mangal Emotional Intelligence Inventory constructed and standardized by Mangal and Mangal (1971). Statistical analysis was done by computing t-test, Findings indicates no significant difference in the academic achievement of higher secondary school students on the basis of Emotional Intelligence, intrapersonal skill, interpersonal management and intrapersonal management but significant difference exist in academic achievement on the basis of interpersonal skill which is found to be significant at 0.05 level of significance.

To find the effect of Nitrogen and phosphors on growth and yield of Lentil investigation was conducted at Sher-e-Kashmir University of Agricultural Science and technology of Kashmir, Shalimar at Pulse Research Sub Station (Habak) Srinagar during rabi 2010-11 the experiment consist of two factors viz four Nitrogen levels (N0 ,N15, N30 and N45) and four phosphorus levels (P0,P25,P50 and P75) was laid out in a randomized block design replicated thrice.

Lambani community has been ardent in retaining traditional symbols despite the influence of modern practices as evidenced by their female dress and adoration practices. These people respect the traditional values and practices. Alcohol liquor is being in use by Lambani community in many ceremonies. Offering of the liquor and receiving of liquor during some ceremonies is very important aspect often depict the status and standard of persons involved. These people have a long history of preparing their own liquor. They have their own special methods of brewing and distillation which is specific to specific tanda (abode). Being the persons engaged in trade, demand of liquor for other community people will also force these people to engage in preparation and supply of liquor. However, law of the land prohibits preparation and storage of liquor without government sanction and standards prescribed. Thus, authorities have targeted this community as being involved in crime of preparing illicit liquor. Involvement of specific community in specific crime needs to be dealt with the knowledge of social-anthropology. Accordingly a study of ceremonies involving utilization of liquor among 18 tandas of Karnataka has been conducted and socio-cultural significance of the factors involved has been discussed.
