INTRODUCTION: SA node controls the rate of heart’s muscular contractions which enables the heart to circulate the blood throughout the body according to the need. Small variations in the heart beat are not harmful but in some cases due to malfunctioning of the heart’s electrical system, the heart rate varies drastically resulting in different types […]
This report explores the uses of composites in modern aircrafts and investigates the technical effects of applying composites to aircrafts. In addition, this report also evaluates the future usage of composites in aerospace industry. Background Composites are defined as engineered materials made from two or more constituent materials with significantly different physical or chemical properties […]
Polyurethanes are broad class of materials used widely in many applications. Polyurethanes are also written as PUR. Polyurethanes also called as urethanes are characterized by urethane linkage -NH- C (=O) – O – . This linkage is formed due to the reaction of isocyanate group with hydroxyl group as shown in the following equation. [2] […]
In the evolution of materials one can strongly agree that science and engineering has played a crucial role into finding new man-made materials. The requirements and living standards currently has advanced thus forcing researchers venturing into development of complex materials. Figure 1 illustrates the relative importance with respect to time and its rate of development […]
Abstract: The project gives a brief introduction to the history of robotics while going on to explain the various types of robots that are built and their classification. A detailed description of the various mechanical platforms and driving mechanisms has been provided. The commonly used robotic designs have also been looked into and their characteristics […]
