Gravity die casting is a repeatable casting process used for non-ferrous alloy parts like aluminium, zinc and copper base alloys. This process is widely used for casting various aluminium alloys. Aluminium Alloys are used in many ‘marine castings’, motor vehicle, railway coaches, thin section castings, aircraft fittings and control parts, and for very large aluminium castings. These applications demand the study of techniques to improve mechanical properties and grain structure of these alloys. Present experiment work shows the effect of mechanical vibration on grain size, inner defect, and mechanical property of aluminium alloys. As a result, this review will provide the improvement in mechanical properties and grain structure of LM-25 alloy by applying mechanical vibrations during the gravity die casting process of alloy.

Pages: 4 - 8
In this paper we discuss prolog and xml as a tool for web search. An XML is the standard for document data interchange and storage now-a-days. Several libraries for XML processing like SAX and DOM are available for many programming languages. Prolog permits to program either declaratively or procedurally. The basis of prolog is formed with first order predicate logic (FOPL). First order predicate logic is expresses with a set of predicate symbols and with a set of connectives. A restricted version of the clausal form which is based on FOPL is used in Prolog. PLXML is a tool in which a module called xml.pl is used to parse XML document with prolog. This module provides the prolog applications an interface to XML document with a Document Value Model.

Pages: 17 - 22
Antenna plays a vital role in Wireless Communication System. Modern and future wireless systems consuming greater demand on antenna design. This leads to a high data rate wireless communication technology called ultra wideband (UWB) with a bandwidth of 7.5GHz (from 3.1GHz to 10.6GHz). There are more challenges in designing a UWB antenna than a narrow band one. The design of Ultra Wideband antennas involves quite different considerations, compared to narrow band antennas. A suitable UWB antenna should be capable of operating over an ultrawide bandwidth as allocated by the FCC. This paper gives an overview of UWB antenna designs and the paper also confers the existing survey works followed by discussion of all the significant literatures related to the topic.

The underpass of Ahmedabad city (Akhbarnagar underpass, Naranpura underpass, Incometex underpass, Mithakhadi underpass, Thaltej underpass, Parimal garden underpass, Shahibaug underpass) are waterlogged every year during monsoon due to which the whole traffic systems gets blocked for hours. Akhbarnagar underpass has a major issue such as traffic, water logging in nearby areas, spreading diseases by water, blockage of storm drain & backflow of suction valve. Surrounding topography, Road gradient, population data, rainfall data of previous year, sewer network analysis and improvement in pump capacity is required to solve this problem. Also, vacuum sewerage system, kerb drain system, improvement in sewer network is the most important possible solution for fight against storm water. Defects in current situation of underpass will overcome by using Quantum GIS & Google earth pro software data, AutoCAD.

This paper is about Rurbanisation of the Pratappura (Balva) village, Gandhinagar District, Gujarat, India. Today world is growing fast so due to migration of people from rural area to urban area is increase daily thus rural area are not develop well compare to urban area. So today’s biggest, issue is migration of people from rural area to urban area. Therefore, in Vishwakarma Yojana Phase IV we will work on rural issues and problems, listing out existing amenities and give best economical solution. It is the project towards making Rurbanisation by providing the social infrastructure, physical infrastructure, socio-cultural infrastructure facilities with method of giving Redesigning, Reimaging, Repair & maintenance, and Sustainable planning for basic need of village. It is about providing urban level facility in rural area. So migration of people urban to rural area decrease and remigration of people are possible. In village there are some infrastructure facility is not available like primary health center, solid waste management, public library, pond and public toilet. So we give the solutions, design, sustainable planning and cost estimation for infrastructure facilities for Pratappura village.

One of the Earthquakes occurred in the Indian Ocean at the Western coast in the year of 2004. In the aftermath of the tsunami, after tsunami data has emerged from field studies in several affected countries indicating that mangrove forests have played a critical role in saving human being lives and property. The trees of Mangroves have shown very successful results among the sea and ocean shore evolution with respect to time. In many extreme conditions Mangroves trees have boundaries of protection over tsunamis. The area required for the mangrove forest for resistance of tsunami of different magnitude is calculated by the tsunami hazard mapping and mangrove mapping with the help of SRTM data and Bathemetric data in global mapper software.

Pages: 40 - 44
In this paper, we propose a modern method of tracking in which it detects multiple moving objects in videos compressed per H.265/HEVC standard. Our proposed paper work largely depends on motion vectors (MV) and block types obtained by partially decoding the video bit stream and occasionally uses pixel domain information to distinguish between two objects. In this work an approach to detect the moving object in compressed domain HEVC is discussed which is used in video surveillance system. Because High Efficiency Video Coding (HEVC) has a large potential to identify events by reusing coding structures in HEVC, which saves vast extent of computational resources. Here the feature Motion Intensity Count (MIC) makes use of motion vector, coding unit and prediction unit of HEVC. Our extensive experimental results demonstrate that the approach provides the remarkable performance and can classify moving person and vehicles accurately and robustly.

Pages: 45 - 50
In power engineering society, sinking the power loss in transmission lines and/or minimizing the voltage deviation at the load buses by controlling the reactive power is referred to as optimal reactive power dispatch (ORPD). ORPD is necessary for safe operation of power systems with regard to voltage stability. In this paper, the nature inspired Differential Evolutionary based Bat Algorithm (DEBA) is introduced to solve optimal reactive power flow problem in power systems. Generator bus voltages, transformer tap positions and switchable shunt capacitor banks are used as variables to control the reactive power flow. DEBA was tested on standard IEEE 30 bus system and the results are compared with further methods to prove the effectiveness of the new algorithm. The results are quite encouraging and the algorithm is found to be simple and easy to employ.

The cost of fuel and the effect of emission of gases from the burnt fuel into the atmosphere, this necessitated the use of the abundant solar energy from the sun as a source of power to drive a agri-cutter. A solar powered agri-cutter was designed and developed, based on the general principle of mowing. The designed solar powered agri-cutter comprises of direct current (D.C) motor, a rechargeable battery, solar panel, a stainless steel blade and control switch. Mowing is achieved by the D.C motor which provides the required torque needed to drive the stainless steel blade which is directly coupled to the shaft of the D.C motor. The solar powered agri-cutter is operated by the switch on the board which closes the circuit and allows the flow of current to the motor which in turn drive the blade used for mowing. The battery recharges through the solar charging controller. Performance evaluation of the developed machine was carried out with different types of grasses. The machine was found to have an efficiency of 93% and a field capacity of 1.11 × 10 -4 ha/hr. No significant difference was observed with the height of grasses at 5% confidence level.
