The power required to propel a new ship is subject to a formidable number of variable items. The family tree of power for propulsion (Fig. 1) shows these divided into two main groups. One is concerned with the resistance to motion caused by the interaction of the hull of the ship with the surrounding water

Two tendencies often occur in the process of translation. One is going after smooth reading and beautiful language at the expense of the true meaning of the original, the other is rigidly sticking to the original words, and the translation turns out to be obscure [ əb'skjuə ] 难解的,含糊的and hard to understand

Nobel Lecture, June 2, 1920 The genesis and present state of development of the quantum theory If i take it correctly that the duty imposed upon me today is to give a public lecture on my writings, then i believe that this task, the importance of which i am well aware through the gratitude felt towards the noble-minded founder of our Foundation, cannot be more suitably fulfilled than by my trying to give you the story of the origin of the quantum theory in broad outlines and to couple with this, a picture in a small frame of the development of this theory up

Understanding materials, their properties and behavior is fundamental to engineering design, and a key application of materials science. Written for all students of engineering, materials science and design, this book describes the procedures for material selection in mechanical design in order to ensure that the most suitable materials for a given application are identified from the full range of materials and section shapes available. Extensively revised for this fourth edition, Materials Selection in Mechanical Design is recognized as one of the leading materials selection texts, and provides a unique and genuinely innovative resource

This book describes semiconductors from a materials science perspective rather than from condensed matter physics or electrical engineering viewpoints. It includes discussion of current approaches to organic materials for electronic devices. It further describes the fundamental aspects of thin film nucleation and growth, and the most common physical and chemical vapor deposition techniques. Examples of the application of the concepts in each chapter to specific problems or situations are included, along with recommended readings and homework problems

Operations Management Refers to the management of the production system that transforms inputs into finished goods and services o Production system: the way a firm acquires inputs then converts and disposes outputs oOperations managers: responsible for the transformation process from inputs to outputs Operations management seeks to increase the quality
