DTN is a mobile ad-hoc network. It is a network of similar networks in which nodes are not connected with each other all the time by using wireless connections. Traditional networks TCP/IP and MANET are responsible for sending the data by connecting the devices all around the world, but the main assumption of traditional networks is that it fails to transmit the data when end to end path does not exist. DTN provides the communication in the challenging environments where end to end path does not exist. Energy is a vital factor to deliver the message from the source to destination. Existing routing protocols in DTN are using so much energy for transferring messages from source to destination. Therefore to reduce energy consumption a new improved algorithm named as Prophet new routing algorithm has been proposed in this work. It is a hybrid approach of epidemic and prophet routing protocol. It makes a priority list to deliver the message and deliver the message according to this priority list. Experimental results are shown by using ONE simulator for the various routing algorithms in DTN by considering the parameters Energy, Overhead Ratio, Average Hop count, packet delivered and packet delivered probability .In this work, the comparison of this new routing algorithm is shown with the Epidemic and Prophet routing algorithm on the basis of energy parameters and Overhead Ratio, Average Hop count, packet delivered and packet delivered probability Experimental result shows that prophet new routing algorithm gives better result than the Epidemic and Prophet routing protocols in the both cases delivery of message and energy consumption.

Year: 2016, Volume:3, Issue : 7
Pages: 138 - 141
A Genetic Algorithm (GA) is a method of solving both constrained and unconstrained optimization problems based on a natural selection process that mimics biological evolution. GA works on the Darwin’s principle of “Survival of fittestâ€. Initialization, crossover, mutation and selection are the operations of GA. Pipe sizing optimization is a NP hard constrained type of problem with discrete pipe diameters. Many researchers have tried to solve the problem of pipe sizing with Evolutionary optimization methods like Genetic Algorithm, Ant Colony Optimization, Particle Swarm Optimization, Differential evolution, Shuffled Complex Evolution, Simulated Annealing, Memetic Algorithm, Tug of War, Water Cycle algorithm, Shuffled Frog Leaping Algorithm and Harmony Search method. A brief review has been carried out for use of Genetic Algorithm in Water Distribution Network and presented in this paper.

Pages: 142 - 146
In recent years, there have been an increasing number of structures using piled rafts as the foundation to reduce the overall settlement. For cases, where piled raft is subjected to a uniform loading, the use of identical piles can improve the performance of foundation. Extensive research has been performed in the past to examine the behaviour of piled raft. In this paper, the behaviour of piled raft supported by identical piles is examined by using computer program ANSYS based on Finite Element Method. Full interaction between raft, piles and soil which is of major importance in the behaviour of piled raft is considered in the analysis. The interaction between identical piles subjected to vertical uniform loading is examined. Program ANSYS can be used for the analysis of piled raft subjected to vertical loadings in which the base of raft is treated being rough and slip along pile-soil interface is allowed in analysis. By having a rough raft base, there is significant effect on vertical movement of raft base, there is significant effect on vertical movement of raft due to lateral resistance of also soils and piles.

Development of High strength Concrete using Rice husk ash and Slag: Hectic industrial activities are envisaged by India and the other developing and under developing countries aiming in this twenty first century, for gigantic improvement in Civil Engineering. India presently is facing problems due to pushing up the cost of construction materials. Already a partial substitution of fly-ash was used for ordinary Portland cement. High strength and high performance concrete are being widely used all over the world. Most of the applications of high strength concrete have been found in high rise buildings, long span bridges etc. The potential of rice husk ash as a cement replacement material is well established .Earlier researches showed an improvement in mechanical properties of high strength concrete with finely ground RHA as a partial cement replacement material. One of the agro-based wastes in our country is rice-husk. Some progress has been made to convert this rice-husk to ash by incineration and use it as a partial substitute replacement for the ordinary portland cement. Rice-husk ash contains 85-95% silica when open burnt and ground to a fineness of 16000Sq-cm/gm. Some investigations were reported on using rice-husk ash concretes and were shown to be good when comparable with concretes with no replacements. Another such mineral admixture is ggbs, confirming to IS12089 which is also a bi-product of iron manufacture industry. Due to its highly cementitious nature, when ground to cement fineness, hydrates like cement. The ground granulated blast furnace slag is a waste product from the iron manufacturing industry, which may be used as partial replacement of cement in concrete due to its inherent cementing properties. This paper presents an experimental study of compressive Split tensile and flexural strength of concrete prepared with Ordinary Portland Cement, partially replaced by Rice husk ash and ground granulated blast furnace slag in different proportions varying from 0% to 25%.Hence a project work is planned to check the suitability of use of RHA and GGBS in developing High strength cement concrete.

Pages: 155 - 161
High Strength Concrete: The term high-strength concrete (HSC) is generally used for concrete with compressive strength higher than 41 MPa. ACI Committee had defined High Strength Concrete (HSC) is the concrete that can attain specified compressive strength for design of at least 41 MPa, or more. With the development of high grade cement and availability of proper mineral admixtures and chemical admixtures, it has become quite common to adopt concrete with compressive strength of 60 MPa and above. Development of high strength concrete has made it possible to build taller and long span structures. Fibre Reinforced Concrete: Plain concrete and High Strength Concrete possesses a very low tensile strength, limited ductility and little resistance to cracking. Internal micro cracks are present in the concrete and its poor tensile strength is due to the propagation of such micro cracks. In plain concrete, structural cracks (micro-cracks) develop even before loading, due to drying shrinkage or other causes of volume change. The width of these initial cracks is few microns, but their other dimensions may be of higher magnitude. When loaded, the micro cracks propagate and open up, and additional cracks form in places of minor defects. The development of such micro cracks is the main cause of inelastic deformations in concrete. The addition of small closely spaced and uniformly dispersed fibers to concrete would act as crack arrester and would substantially improve its static and dynamic properties. This type of concrete is known as Fiber Reinforced Concrete.

Wireless sensor networks are one of the most interesting and challenging research domains of our time. They have a great potential to be deployed in wide critical applications, such as military monitoring, health care as well as civilian applications. The highly sensitive nature of collected information makes security in these special networks a crucial concern. Owing to the hostile nature of their deployment environments, the wireless medium and the constrained nature of resources on the tiny sensor devices used in such networks, security poses more severe challenges compared to the traditional networks. As attacks to any part of the hardware or software may gives significant damages to these networks. Indeed, the development of effective and efficient defense mechanisms to those attacks must be addressed at every stage of the system design. Wireless sensor networks have attracted a wide range of disciplines where close interactions with the physical world are essential. The distributed sensing capabilities and the ease of deployment provided by a wireless communication paradigm make WSNs an important component of our daily lives. Energy conservation emerges as one the most critical aspect in hardware and software related design issues. Also other related main issues include specialized hardware, software and operating system, synchronization, QOS, security, architecture and data collection related aspects with minimum communication and computation costs. This paper provides an overall view of various such issues for the better understanding of this field for the overall benefit of the research community working in this area.

Pages: 167 - 172
There are various types of solar water heating systems available in the commercial market to fulfill different customer’s demand, such as flat plate collector, concentrating collector, evacuated tube collector and integrated collector storage. A cost effective cum easy fabricated V-trough solar water heater system using forced circulation system is proposed. Reason behind the selection of v-trough is that it is not only economical but also heat transfer rate is increased by positioning the glass plate at angle of 60degree. And also base plate collector maintaining maximum absorptivity due to given black coating. The radiation which incident on the V-trough are reflected back inside the entire setup and makes less radiation losses. Integrating the solar absorber with the easily fabricated V-trough reflector can improve the performance of solar water heater system. In this paper, optical analysis along with experimental study and cost analysis of the stationary V-trough solar water heater system are presented in details. The experimental result has shown very promising results in both optical efficiency of V-trough reflector and the overall thermal performance of the solar water heater.
