Abstract In work shops and automotive shops, there are frequent needs of tightening and smoothening of screws, drilling, boring, grinding machines. Huge and complicated parts can not be well machined with the help of ordinary machine. In electrical drilling machine power consumption is too high whereas accuracy is not good. Drilling the hole in particular … Read more

Chapter 1: Introduction 1.1 Problem Summary Gasoline/Diesel pump are cheating with common man nowadays. Numerous of the gasoline/diesel pumps today manipulate their pumps, such that it displays the amount as entered, but in truth, the quantity of gasoline/diesel entered in the customer’s tank is very less than the displayed value. The pumps are being used … Read more

CHAPTER ONE INTRODUCTION 1.1. Background The term “identification” means the act or process of establishing the identity of or recognising, the treating of a thing as identical with another, the act or process of recognising or establishing as being a particular person, but also the act or process of making representing to be, or regarding … Read more

Abstract In this paper, numerical simulations and experimental validation were carried out to study the Reynolds number effect on a NACA2415 airfoil type wind turbine. The software “SolidWorks Flow Simulation” has been used to present the local characteristics in different transverse and longitudinal planes. The considered numerical model is based on the resolution of the … Read more

ABSTRACT Over the last decade, the power system has seen a significant rise in the installation of Distributed Generation(DG). Although implementation of DG has several advantages by supporting the system, its steady growth requires special consideration to issues relating to high DG penetration. The challenges faced by integration of DG cover many aspects, extending from … Read more

1. INTRODUCTION ‘ Estimation ‘ Before taking up any work for its execution, the owner or builder should have a thorough knowledge about the volume of work that can be completed within the limits of his funds or the probable cost that may be required to complete the proposed work. ‘ Calculating the quantities from … Read more

Sustainability is the ability for something to be maintained at a certain rate or level, in construction terms it can mean avoiding the depletion of natural resources in order to get environmental balance and to strive for environmental sustainability. Sustainable construction corporates the design and management of structures. It can be broken down into environmental, … Read more

What Is Precast Concrete? Precast Concrete consists of concrete. A mixture of Cement, Water, Aggregates and Admixtures. A method called concrete shuttering (Typically shapes constructed of wood or steel) is used to form the concrete to the desired shape as specified by the Customer. Once cured, these components are then stripped from the mold (usually … Read more

Literature Review 2.1 this chapter presents the state of knowledge and literature review about the effect of thermal shock due to rapid cooling on the recycled glass concrete, furthermore the thermal conductivity of the recycled glass concrete. Glass as waste material is discussed in section 2.1, using waste glass in concrete is discussed in section … Read more

1. Abstract High-performance insulation simply begins with silica aerogel. Within this particular study, Aerogels will be used as a lightweight solid that is compared to gel. The liquid property of the gel serves as the gas which keeps the material’s density immensely low. The air that composes 97% of the solid impedes on the convection … Read more

ABSTRACT Within this report, the development of Glass Fibre-Reinforced Polymers in the 1930s has been discussed, along with their use in industry. They were thought to be resistant to all weather conditions, however after significant periods of time they can develop defects including blistering. They are made of layers of glass fibres and thermoplastic resins … Read more

Wind power and other renewable decentralized energy resources play a bigger part in our energy mix than ever before, this increases the demand on a more complex power system and increases the demand on the power grid on every voltage level. Direct drive the benefits still heavily overweigh disadvantages connected to direct drive, such as … Read more

Multiple terms can been used to describe off-site construction (OSC). These include terms such ‘modular construction’, ‘pre-fabricated construction’, ‘off-site manufacturing’, ‘industrialised building systems’ and ‘off-site fabrication’ (Hairstans, 2015, p.6). Whilst these terms are arguably distinct, they all require buildings, or considerable parts therefo, built at a different location than the location of use (Department for … Read more

Introduction Opening/Mission Statement The aim of the project is to improve the efficiency of train travel by indicating how full a carriage is, which speeds up the boarding and embarking of trains. Objectives To maximise the seating and space usage of train carriages for the benefit of the train company. To improve the comfort of … Read more

“It’s a serious issue. We have oceans and rivers, and we pollute them until they become almost unusable. We’ve done exactly the same with space. We’ve left junk everywhere.” – Melissa Davey expresses her concern in her recent article. Humans have polluted oceans and rivers with their waste. As a consequence, marine and water pollution … Read more
