Study of heat transfer charecterstics of a multiple jet cooling
Abstract
In this work an experimental study of cooling capabilities of impinging water and air jet array is presented. Investigations were carried out using electrically heated test plate. Heat flux in the range of 25 to 200W/cm2, which is a typical requirement for cooling high power electronic components was dissipated using 0.25mm and 0.5mm diameter water and air jets arranged in 7X7 array with a pitch of 3mm. Tests were performed in the Reynolds number range of 1200 to 4500. Results shows higher values of heat transfer coefficient are obtained.The effe ct of positioning of jets are insignificant

Review of Surface Roughness Prediction in Machining Process by Using various Parameters
Abstract
In recent years machine vision system set remarkable achievements, in the inspection process, a few examples like sorting the products in conveyer for the rapid manufacturing process. Even most of the industries following the conventional surface testing methods like stylus profilometer. This review paper has been proposed the list of parameters for Roughness testing and it will be evaluating then matching with suitable methodologies. Most of the research articles deal with Average Value (Ra), Root means Square (Rz), Peak to Valley (Rt). Here we see the details about parameters and various types of algorithms for measuring the surface roughness. As a result, this review concept as used to do the research in various aspects based on the various parameters.

The Uses of Robots in Nuclear Power Plant and MHRD Initiation for Implementation of Awareness in Robotic Technology in India – Part 1.
Abstract
Abstract- Japan was seriously affected in the Second World War (WWII). After the Second World War, the Japanese met a heavy loss of human lives and grief enveloped them. Japan was able to recover from the distress of WWII and managed to become the second-largest economic entity of the world by the 1960s. Japan’s immeasurable growth came by their preference to hard work, sincerity and good discipline. The 26th April 1986 Chernobyl reactor number four accident was considered as man-made disaster because of flaw reactor design with serious mistakes made by the plant operators. The Chernobyl accident is considered to be the worst nuclear disaster in history and it shocked the world, permanently altered a region, and leaves many questions unanswered. A large mass of black corium formed which resembling the foot of an elephant. Japan’s earthquake and tsunami of 2011, also called the Great Sendai Earthquake, a severe natural disaster occurred in northeastern Japan on March 11, 2011. This most powerful earthquake recorded in Japanese history had a magnitude of 8.9. The massive March 11 earthquake and tsunami knocked out Fukushima Daiichi Nuclear Power Plant’s, reactor cooling systems, where workers were battling to prevent radiation leaks and a total meltdown. The tremors were the result of a violent uplift of the seafloor 80 miles off the coast of Sendai, where the Pacific tectonic plate slides beneath the plate Japan sits on. The earthquake occurred at a relatively shallow depth of 15 miles, meaning much of its energy was released at the seafloor. This paper describes the meltdown position of the uranium reactors in Chernobyl and Fukushima Daichii power plant and the need for the development of the Robot to find out the meltdown position of the reactor.

The Uses of Robots in Nuclear Power Plant and MHRD Initiation for Implementation of Awareness in Robotic Technology in India – Part II.
Abstract
Abstract-Japan’s earthquake and tsunami of 2011, also called the Great Sendai Earthquake, occurred at a relatively shallow depth of 15 miles, meaning much of its energy was released at the seafloor. The massive March 11 earthquake and tsunami had a magnitude of 8.9 knocked out Fukushima Daiichi Nuclear Power Plant’s, reactor cooling systems, where workers were battling to prevent radiation leaks and a total meltdown. Instead of a human, a robot is used to find the meltdown position of the Uranium reactors in Fukushima. Certain considerations that restrict the use of particular robots are discussed. This paper thoroughly describes the steps taken by the Ministry of Human and Resource Development for their initiation for skill development in Robotic Technology in India. E-Yantra is a project sponsored by MHRD through the National Mission on Education through Information and Communication Technology (NMEICT), New Delhi to bring awareness and development of skills among the students about Robotic technology. IIT Mumbai is conducting e-Yantra Robotics Competition for undergraduate students in Engineering/ Science/ Polytechnic colleges with no registration fee.

Analysis of multi-story building in different seismic zone by STAAD PRO v8i
Abstract
The principle objective of this project is to analyse a multi-story building (G+21) using STAAD PROv8i.The analysis involve load calculation manually and analysing the whole structure by STAAD PRO. The design method used in STAAD pro is based on limit state method conforming to Indian standard code of practise. Initially we started with the analysis of simple 2D frame and manually checked accuracy of software with our results. The results prove to be very accurate. We continued with our work with some more multi story 2D and 3D frame under various load combination. Our final work is on proper analysis of G+21 3D frame under various load combination in different seismic zone.
