Video Transmission in Heterogeneous Network with Improved QOS
Wireless communication systems that consist of cellular, WLAN and Wi-Max access networks simultaneously are termed as heterogeneous wireless networks. Heterogeneous networks connect computers and other devices with different protocols. In the existing system the Greedy Approach was used for video transmission in heterogeneous network. It minimizes the video quality distortion by scheduling the most valuable packets for transmission. But there is a loss occurs when large number of packets is transmitted. The proposed work considers Wi-Fi and Wi-Max in the heterogeneous network for transmission. In this process for multi-resolution video transmission to heterogeneous clients and for channel adaptation, Scalable video coding (SVC) is being developed in response to the need of robust video delivery for heterogeneous clients. The clients receive and decode different fractions of the video bit stream to obtain the desired resolutions and qualities. Multicast probe (MP) frame was initiated which contains the information of the video bit stream and the timer starts for the multicast response (MR) frame. Upon receiving the MP frame, if a client does not subscribe to the multicast group, the MP frame is simply ignored. Otherwise, an admitted client estimates the signal-to-noise ratio (SNR) and path loss of its wireless channel. The simulation results are performed using MATLAB.

Irrigation Water Management and Crop Production
Agriculture being a key element of the national economy is challenged by variety of problems in development planning. Among these the major ones are climatic changes, topographic constraints, population pressure, ecological degradation & low level of technological advancement, so it needs good potentials of agricultural development. One of the mitigation to reduce challenges of this development is Irrigation practices Looking at this Irrigation Project area, it is with trace amount of rainfall over the year, this does have direct impact on human & cattle population, so it has to be supported by irrigation. Residents of the area develop Teff, Maize & sorghum though the available rain is not promising to harvest yield that even can feed few months. There is no promising grazing area for the cattle of the area too. Irrigation from its very nature has the capacity to solve animal feeds. The methodology used in this development study was aimed at plainly defining and describing the agronomic situation of the area and out lining the major crop production constraints and developing recommendation for implementation. Primary and secondary data were collected from the Kebele development agents, farmers and Wareda agricultural and development office using checklists through group discussion and key informant interview on crop production, cropping pattern, farming practice and production constraints. Crop water requirements of crops are computed using crop wat 4 windows model. In general, as a conclusion the agro-climatic condition of the project site, the suitability of the soil for crop production, physical feature of the command area and the availability of irrigation water are suitable for development of irrigation. Despite the above facts, the sustainability of the project is very much dependent on the full participation of the beneficiaries in all aspects of the project implementation. The participatory approach will create a sense of responsibility and ownership and greatly contributes to the success of the irrigation schemes constructed in previous years.

Effect of the Fungicide Dimethomorph at Different Application Rates on Enzyme Activities in Groundnut (Arachis Hypogaea l.) Soils
Soil microbial diversity is indispensable to maintain functional diversity and enzyme-mediated critical soil processes that detoxify soil from environmental pollutants, like pesticides. Thus, the present study was carried out to assess the effect of different concentrations of the fungicide dimethomorph on the activities of phosphatase, and urease, of black and red soils of groundnut cultivated fields of Anantapuramu District , Andhra Pradesh, India

Study Of Mechanical Behavoir Of Composite Material By Vibration Analysis
In present time there is an increasing need for an alternative material to conventional materials. Growing interest in using environmental friendly materials brings natural fiber made the composite material in focus. They are strong, lightweight, cheap and biodegradable. But one needs to check whether its properties satisfy that of existing material. The target of the study is to experimentally justify biaxial fiber composite as a promising alternate material. The polymer composite samples are made with natural/synthetic fiber as reinforcement and a synthetic resin as matrix material. To find its natural frequency and damping of the composite materials, vibration test is carried out. ANOVA technique is used to find the level of the parameter.

Implementation of Secured Sensor Nodes Using Cryptographic Algorithms
Application of wireless sensor networks (WSN) to commercial, home environments and military purpose are increased in wide range. As the wireless sensor networks continue to grow, they are vulnerable to attacks and hence need for security mechanisms. Identifying suitable cryptography for WSN is important challenge due to limitation of energy, computation capacity and storage resources of sensor nodes. For this purpose, Cryptography plays a vital role in securing the data in W SN. In this paper we implemented two symmetric cryptographic algorithms algorithms: block cipher AES (Advanced encryption standards) and the Lightweight block cipher PRESENT. Our main aim of implementing the symmetric cryptographic algorithms in sensor nodes to provide secure communication which guarantees the confidentiality, integrity and avoids key exchange via unsecured channel that impose real threats. The experimental results are carried by implementing these algorithms in Atmega 32 bit microcontroller using simple C codes.

Experimental Investigation of Mortar Cube with Pumice Powder and Ceramic Tile Powder
An experimental investigation was carried out to evaluate the properties of cement Mortar. In this project study, ordinary Portland cement is replaced partially with pumice powder and fine aggregate is replaced partially with ceramic tile powder. In this research is to study the utilization of ceramic waste as a partial replacement of fine aggregate in a mortar. In this experimental investigation, prepare mortar cube of size 70.7mm x 70.7mm x 70.7mm with mix proportion 1: 3. The aim of this study is to determine the optimum % replacement of pumice powder in mortar cubes. .Cement mortar is made by replacing cement with pumice powder of different percentages like 5%, 10%, 15%, 20% & 25% with curing of 3, 7 & 28 days. The various combinations of pumice powder and ceramic waste powder were added to the mortar. Compressive strength test, splitting tensile strength test, water absorption test and the density test were performed and the results were analyzed. Mortar cube shows light weight behavior by replacing cement with pumice powder. The density of mortar is decreasing by adding pumice powder. The density of mortar cube is increasing by adding pumice powder and ceramic tile powder. Mortar cube shows almost similar strength compare to conventional mortar by adding pumice powder and ceramic tile powder.
