Abstract: There are various problems encountered in the pneumatics actuator in design as well as in manufacturing processes like casting etc. Here, mainly focusing on reduction of the friction that produce in between pneumatic piston-cylinder arrangement during statics and dynamics condition of working of actuators .So, that it can increase the overall working efficiency of pneumatic machine. The idea of project is to maintain the friction in machine as per the application in the heavy loaded and long vehicles like railway trains. For that, use of different coating materials on Piston leads to fulfill this requirement. Coating on Piston ring can be useful to reduce the friction in Piston- cylinder arrangement.

Abstract: Basalt fiber is an inorganic fiber which uses natural basalt ore as raw material. The basalt fiber has natural compatibility, excellent mechanical properties, high temperature, and acid and alkali resistance. The objective of this paper is to explore the potential use of natural basalt fiber in improving the geotechnical properties of organic soil. Both the content and length of basalt fiber were considered in this paper. The study has been conducted with three different fiber contents of 0.05%,0.10% & 0.15% by weight of raw soil. For each fiber content 10mm, 20mm, 30mm lengths of fiber were used........

Abstract: Treatment is an operation or combination of operations involving typical heating and soaking at a temperature for a period of time and methods. The aim is to obtain a desired predetermined property like hardness. Knowing the hardness of any metal or alloy is important, as this value gives you an indication of its ability to form and maintain a shape and is also a guide to its durability. To ensure that any metal or alloy (Al-Si) component is suitable and adequate for the designed purpose, it may need to be exposed to a selected range of typical treatments. The treatments are conducted in such a way so as to ensure that the required combinations of these parameters. A413 is.........

Abstract: This work presents the use of grinded Corn (Guinea Corn (Sorghum bicolor L.) and maize (Zea Mays L.)) seeds as admixtures of concrete composites. Cement concrete with different concentration of admixtures were tested to deduce the admixture effect on concrete properties like consistency, workability and compressive strength. The results obtained, using both admixtures were compared using the F-statistics to check for significant difference between the concrete properties. Models to predict the concrete properties for different concentration of grinded corn seeds were developed and compared.........

Abstract: The simulation of combustion of Onyeama coal in a batch reactor using COMSOL MULTIPHYSICS model was carried out in order to develop necessary baseline combustion reaction data and also to provide data for the assessment of coal combustion performance at high temperatures. The volatile matter component of Onyeama coal and some parameters from Illinois No.6 coal were used for the simulation. The volatile matter combustion reaction rates were converted into batch reactor space using air to fuel ratio at set tolerance levels and initial temperature of 800K. Key indices such as model volatile gas specie evolution rates, calorific value and gas temperature profiles were computed using three and thirty three reaction kinetic.........

Abstract: Reducing weight while maintaining structural integrity is one of the key challenges of Formula SAE teams, during the design of suspension of the formula car. The purpose of this paper is to present experimental data on designing and optimizing a carbon fibre suspension system for formula cars. The reason carbon fibre suspensions are favoured over the current steel suspensions are because they can reduce the weight of the suspension system by 75 %. Pull tests on a universal testing machine were performed on two different specimens made of carbon fibre tubes with different inserts bonded on each tube i.e. mild steel and aluminium insert.........

Abstract: The twelfth FYP shows large interest in investments in infrastructure sector by India, so there is need for different types of contract that will satisfy the purpose. EPC Engineering, Procurement and Construction are a common type of contract for large scale projects such as roads, telecommunication, petroleum, real estate etc. Here the contractor carry's out the designs of project, procure materials and equipment's required as per the specifications and delivers the project in agreed duration of time. Failing to deliver the project in stipulated time will make the contractor to bear the liability........

Abstract: This paper presents the concept of the most inexpensive, autonomous method of moving a car on road without the necessity to burn fossil fuels or any expenditure of non-renewable source of energy in any form to run an engine. In contrast to any conventional methods present today, it works on the principle of coulombic forces of attraction between two oppositely charged bodies along with the involvement of an unbalanced torque on the wheel to propel it in a unique direction. It exploits the concept that under the given conditions of how the wheel is built, electrostatic forces of attraction exceed the gravitational pull.It harnessesinfinite source ofelectrostatic energy to produce mechanical torque about the rotating wheel's instantaneous axis of rotation, a promising way to cut off the world's automobile exhaust to an absolute nought

Abstract: Expansive soil is truly assumed the notoriety of being the most difficult and problematic soil when this soil is used in field as a foundation material because of its low bearing capacity, high compressibility and high volumetric changes during dry wet seasons. Structures especially lightly loaded, founded on such soil deposit are severally damaged, because of the swell-shrink behavior with water content change, this necessitate 'In-situ' ground improvement. 'In-situ' expansive clay has certain water imbibing capacity of varying magnitude depending on its initial water content, by making the use of this property, one can modified soil behavior by using water soluble chemical........
