First of all, the sensors which we’re going to use, need to be waterproof. The communication between the vehicle and the computer will be underwater. This can be realized by using beacons. For communication, we can use a ultrasonic sensor which is waterproof and cost around $11,- and has the following specifications: Electrical properties: ‘ … Read more

Fracking is a fairly new method of extracting natural gas. Fracking can be defined as a method to remove natural gas from the ground. Another way to describe fracking also known as hydraulic fracturing is the process of creating fissures in underground formations to allow natural gas to flow (Natural Gas Extraction – Hydraulic Fracturing … Read more

The role of requirement engineering phase in the development of software product servers as a strong base for the successful completion. There have been numerous models presented so far, in this phase, to improve the mistakes that are supposed to be the part of requirement engineering process. It is also to make the further development … Read more

Water can be found in concrete as product of the hydration during the mixing or as a result of filtration induced by cracking and structural joints. When this water freezes, it creates pressure in the pore network of the concrete and generate tensile stresses that produce more cracking, surface scaling and possible loss of the … Read more

Building Design and Construction is the process of creating a plan and adding structure to real property or construction of buildings. In the modern industrialized world, construction usually involves the translation of designs in to reality. A formal design team may be assembled to plan the physical proceedings with the other parts. The design usually … Read more

Helicopters are extremely useful pieces of flying equipment, with the ability to both take off and land vertically. This along with being able to hover in a given place and fly in any direction, including backwards and to either side, means that they have a huge amount of uses worldwide and in many different environments, … Read more

Many engineering applications with baffles such as thermal regenerator, Shell and tube type heat exchanger, Internal cooling system of gas turbine blades, radiators for space vehicles and automobiles, etc. are applied to enhancement the heat transfer. Baffles are applied as turbulence promoters. Baffles are one method that used to increase the thermal performance. Thermal boundary … Read more

  Summary: Plastic waste and its impacts The use of plastic is one the world has come to really rely on. It is perhaps the most used solid commodity in the world as its use and application cuts across all industries and sectors. Because of its adaptability, flexibility and low cost, there is a huge … Read more

EXECUTIVE SUMMARY In recent years, the construction industry has been a visible shift from owner managed construction projects to EPC project with independent but different disciplines of construction. The EPC contractor takes the responsibility of completing the project in a given cost and time frame and acts as a single point interface between the promoter … Read more

Abstract The primary aim of this project is to design and analyse a Ranque-Hilsch Vortex Tube (RHVT). To get the project up and running research was undertaken to investigate the thermodynamics of the RHVT. As the RHVT obeys the first and second laws of thermodynamics, the laws are explained to gain a basic knowledge of … Read more

Abstract: This article discusses about the development of shape altering morphing wings. It includes a brief discussion about the concept of morphing wings or shape changing wings, which can be considered as the future of aircrafts. It also provides information about the materials used for wings along with the use of the Shape Memory Alloy … Read more

ABSTRACT: Recent technological developments have made easier the application of reverse engineering. In this paper, a reverse engineering approach for the development of the products has been presented, This approach has been based on the scanning of the initial product, followed by the redesign of the initial product, the manufacturing of the redesigned product through … Read more

Our initial results showed positive response from a majority of companies that we surveyed. However, a subsequent follow-up study of the inner working of these companies presented different scenarios and therefore helped us to understand the real problems facing these companies. Our in-depth research shows that among Indian automotive companies, there has been a remarkable … Read more
