Abstract: Today in India eco-friendly vehicles are spreading like fire. It includes CNG, LPG, and Electricity/Solar Powered engine/motor vehicles. Their efficiency is ranging from 75%-89% efficient as compared to gasoline & diesel variants whose efficiency is almost 25%-35%. But if we are taking about air compressed engines it is up to 95%. Vehicles working on gasoline (petrol) and diesel engines produce exhaust like CO, CO2N2O etc. Whereas vehicles working on CNG, LPG, Battery Power and Compressed Air don't produce any kind of exhaust or harmful gases. Now days,

Abstract: In this paper the behaviour of roller compacted concrete pavement with fly ash is examined. In the preparation of fly ash roller compacted concrete (FRCC), the maximum aggregate size was 20mm in all of the mixtures which were designed using maximum density method. The cement content of the control mixture was 318kg/m3.Cement was replaced at various percentage levels such as 20%,40%,and 60% besides control concrete was also prepared for comparison purpose. Compressive strength, split tensile strength, flexural strength were determined at 3,7 and 28 days. Test results indicate that the mixtures where cement was substituted with fly ash, increasing the fly ash content caused reduction in compressive, splitting tensile and flexural strength values at all of the ages up to 28days.

Abstract: GFRP (Glass Fiber Reinforced plastic) composite materials are find many applications in engineering fields like mechanical and civil engineering applications. It is because of the properties of these materials like light weight when compared to other materials, durability, rust proof and many more. The composite cylindrical shells are being used very widely in underground pipelines, Aerospace industries, submarines and so on. In present study, the buckling of thin walled glass reinforced polymer cylindrical shells with and without cutouts has been investigated by applying axial load on the shells. The results which were obtained in this experiment will show how the imperfections like cutouts will affect the buckling behavior of the shells.

Key words: Composite, cylindrical shell, cut outs, buckling.

Abstract: Heat dissipation is a major aspect in many applications involving thermal energy. Thermal performance can be enhanced considerably using fins. In this paper perforated fins with varying contact ratio with base plate are analyzed for the augmentation of heat transfer from the base plate. Comparison of Nusselt number with Reynold number has been done for various configurations of fins in this study.

Keywords: Ansys Fluent 13.0, base contact ratio, CFD and Finite Element Method, perforated fins.

Abstract: In a restaurant waiting for service is a common phenomenon for the customer. Restaurant owners are not concerned about the matter of waiting customer though they do not want their customer would go another competitor's door. There are several determining factors for a restaurant to be considered as a good or a bad one. Taste, cleanliness, the restaurant layout and settings are some of the most important factors. These factors, when managed carefully, will be able to attract plenty of customers, However, there is also another factor that needs to be considered especially when the restaurant has already succeeded in attracting customers. This factor is the customers queuing time.

Abstract: Fishery Port City Beach is located in the district of Situbondo Banyu Putih which is approximately 50 km from the city center. Exact location of the fishery port in the district directly adjacent to the Banyu PutihBanyuwangi industrial plant which contained fish canning factory in the district Muncar.In development ,thisport functions not only as a fishery port but also, as the crossing place to theSepudi island which is included of Madura district. Different from the original plan, transportation within the port has changed. Reserved parking area no longer function optimally.

Abstract:At present, it is highly required from the automobile sector to develop clean technologies with lower fuel consumption for ambient air quality improvement, green house gas reduction and energy security. Furthermore, due to continuously stringent emission legislation and the fast depletion of the primary energy resources, the development of new highly efficient and environment friendly combustion systems becomes of paramount importance and hence research need to be done in this area. One such combustion system is Homogeneous Charge Compression Ignition (HCCI) technology.

Abstract: Over the last thirty years composite materials, plastics & ceramics have been the dominant emerging materials. The volume & number of applications of composite materials have grown steadily, penetrating and conquering new markets relentlessly. The composites have already proven their worth as weight-saving materials. The increasing demand for using environmentally friendly materials leads to usage of natural fibres. The fibres are reinforcement with polymers have gained importance due to its better properties. Natural fibers are not only strong and light weight but also relatively very cmaterials cheap and these fibers improve the environment sustainability of the parts being constructed.

Abstract:The principal objective of this paper is to demonstrate the capability of graphene in making energy efficient solar panels inexpensively. Comparing to silicon solar cells , graphene solar cells are more efficient and provides double the power output in less time. Checking out the difference for the selection of elements between silicon and graphene, graphene leads with respect to properties like electrical conductivity, thermal conductivity, material strength and flexibility. The main difference is its inexpensiveness. Where there is increase in population and insufficient power production in villages ,small scale industries ,graphene solar panels will be installed to gain additional power without any problem .Researchers and industrialists quote graphene as the nearby future for power supply.

Abstract: In this paper an experimental study was performed to observe the effect of fill volume ratio, inclination angle and heat input supplied to understand the heat transfer characteristics of a two phase closed thermosyphon (TPCT) charged with glycol and water. For the experimentation purpose four copper TPCT's of same dimensions were designed which are filled with aqueous solution of Propylene Glycol (PG) with 50% purity and De-ionized (DI) water with fill volume ratio of 40% and 60% and are heated with hot water in evaporator jacket from 60°C to 90°C.
