major that interests me is materials engineering. It is because materials engineering is a major field that applies fundamental knowledge of the structure and properties of material that will be developt to be new materials that can be used in everyday life or for the most advanced technologies.this interdisciplinary inverstigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. The information from materials engineering is applied in

orientation of a piezoelectric material during the design and manufacture of a device. There are certain mechanical parameters which plays a great role in piezoelectric effect. 2.2.1 Mechanical Strain The mechanical strain S which results from the application of a stress T is linearly proportional to the compliance S (S-1= Young’s modulus) within the elastic deformation region of the stress-strain curve of the material (below the yield strength )

due to coefficient of thermal expansion (CTE) mismatch between the respective materials within the package as it cools to room temperature. Printed circuit boards (PCB) are designed and manufactured with a variety of polyamide materials such as solder mask‚ metallic material such as copper trace‚ composite materials such as prepreg and core material. Polyamide materials such as solder mask and composite materials such as prepreg play important factor on the total deformation of laminate package

Jaw crusher is mainly used for coarse crushing and medium crushing in the departments of mining‚ building materials and infrastructure construction. According to the feeding width‚ it can be divided into large‚ medium and small sized. The jaw crushers have many advantages such as simple structure‚ easy manufacturing‚ reliable working condition and convenient operation and maintenance. Major Advantages of Jaw Crusher 1. Effectively solves the problem of high operation rate and little maintenance

psychology became a science and distinguish from the older discipline philosophy and form modem psychology. Modern psychology can be considered a product of 19th century thought because this is the time when the field developed its own independent methods and became its own independent discipline. Philosopher studied human nature via speculation‚ intuition and generalization based on their own experience‚ while psychology applied the tool and methods of biological and physical science‚ with controlled

Section:-M2R16 Roll No.:-B16 Subjet:-MEC208 INTRODUCTION For a crystalline solid we have tacitly assumed that perfect order exists throughout the material on an atomic scale. However‚ such an idealized solid does not exist; all contain large numbers of various defects or imperfections. As a matter of fact‚ many of the properties of materials are profoundly sensitive to deviations from crystalline perfection; the influence is not always adverse‚ and often specific characteristics are deliberately

As stress and mental issues relating to stress grow more prevalent as a result of war‚ post-war‚ and other traumatic experiences‚ more than one generation of people are being affected (Shulevitz 1). As Judith Shulevitz explains in her article‚ The Science of Suffering‚ “The children of the traumatized have always carried their parents’ suffering under their skin” (3). In fact‚ she further conveys to the modern audience through interviews with trauma victims and survivors her purpose to spread information

The philosophy of science is concerned with the assumptions‚ foundations‚ methods and implications of science. It is also concerned with the use and merit of science and sometimes overlaps metaphysics and epistemology by exploring whether scientific results are actually a study of truth. In addition to these central problems of science as a whole‚ many philosophers of science also consider problems that apply to particular sciences (e.g.philosophy of biology or philosophy of physics). Some philosophers
