Executive Summary The purpose of this report is to rapidly familiarize the reader with the use of steam-assisted gravity drainage (SAGD) in the extraction of hydrocarbons from Alberta’s extensive oil sand formations. To that end, it introduces both the Athabasca oil sands and describes the relevance of SAGD to the feasibility of exploiting them. Next, … Read more

Chapter 1: Introduction 1.1 Problem summary and Introduction Cracking is a regular complain in the concrete industry. Cracking occur due to combination of factors. Such as drying shrinkage, thermal contraction, restraint to shortening, sub grade settlement, and applied loads. Cracking can’t be prevented but it can be significantly reduced or controlled when the causes are taken … Read more

Introduction Recently used turbines for power generation and aero-jet aircraft engines applications experience incessant efforts towards increasing the thermal efficiency [1]. Greater efficiency and higher output inescapably need to increase the turbine operating temperature, which needs novel methods to overcome the restraints of hot sections materials [2]. Early, before 25 years ago, the increase in … Read more

ABSTRACT Construction Industry is always on hunt for Innovative Material and Innovative construction technologies. Concrete is the second largest material used on Earth after water. Concrete has proved its worth in the construction industry for being the most robust and durable. However, “Sustainable Concrete” is the need of the hour. Production of conventional concrete is … Read more

1.1 Background Plasma nitriding is one of the surface hardness processes whereby a surface of a material is shot by plasma. Since plasma nitriding is a process, it requires a machine to be able to execute this process. Therefore, introducing the plasma focus device as also known as plasma gun. The plasma focus device (plasma … Read more

Introduction There has always been a need for stronger, harder, more corrosion resistant and generally more versatile metal alloys. The properties, described above are in high demand in nuclear, aerospace, food processing, chemical and metalworking industries [1]. Some examples of specific demands and application requirements for these industries include the making of critical peripheral structural … Read more

The usage of lightweight materials increases in recent years because of that usage of the titanium alloys increases due to its properties. The properties of titanium alloys high strength-to-weight ratio fracture toughness corrosion resistance good fatigue behavior desirable high temperature properties In many nuclear, automotive and aerospace industries prefer to use titanium alloys because of … Read more

1. Introduction Nitinol is a ‘smart’ alloy that exhibits dual unique properties of superelasticity and shape memory combined with excellent biocompatibility. Comprised generally of near equal components of the transition metals, nickel (Ni) and titanium (Ti)  NiTi, Nitinol’s excellent malleability and ductility allow it to be manufactured in the form of wires, ribbons, tubes, … Read more

This literature survey deals with the prior existing studies which explicate SMAs as common studies, at most the Cu-based SMAs studies since those SMAs are very contrastive from old-style materials. Thus , a deeper thoughtful of their thermo- mechanical behavior and the effect of preparing method , heat treatment, alloying element and other factors on … Read more

Abstract: In this study, friction welding process was successfully applied to join a ferritic ductile iron. The microstructures, phase transformation, crack analysis, microhardness and tensile test of the welds were investigated. The welding region was composed of the deformed graphite nodule, coarse pearlite, proeutectoid ferrite and acicular martensite. Highly deformed graphite nodules were distributed along … Read more

This chapter presents an over view of the current store of evolutionary algorithms and their applications. An attempt is also made to study the present applications of evolutionary algorithms in machining processes. Boguslaw Pytlak [1] presented in his paper, the results of multi-criteria optimization of hard finish turning operation parameters of hardened 18CrMo4 steel in … Read more

Introduction The further improvement of the telecommunications networks has enlarged the need of the optical signal processing. The link lengths have grown to thousands of kilometers with no need to convert optical signals back and forth to electric form, and transmission speeds of terabits per second are today feasible. This ever-growing demand for the high-speed … Read more

1.1 Introduction The need to establish sustainable materials within the engineering environment is a vital and immediate challenge for the ever-growing area of civil engineering. This has come even more to light over the past few years with a growing number of environmental problems from flooding to earthquakes becoming more prominent across the world. One … Read more

Introduction Would you sell out a co-worker to get ahead? Make negative statements about another practitioner’s business in an attempt to take out the competition? This paper will review and analyze an article in the code of ethics that pertains to these very concepts: the malicious damage to another practitioner’s business or reputation. The topic … Read more
