| Author(s) : Randolf W. Knoss Publisher : Nova Science Date : 2008 Pages : 691 Format : PDF ISBN-10 : 1604569301 Since first developed in the early sixties, silicon chip technology has made vast leaps forward. From a rudimentary circuit with a mere handful of transistors, the chip has evolved into a technological wonder, packing millions of bits of information on a surface no larger that a human thumbnail. And most experts predict that in the near future, we will see chips with over a billion bits. Quantum dots are small devices that contain a tiny droplet of free electrons. They are fabricated in semiconductor materials and have typical dimensions ranging from nanometres to a few microns.The size and shape of these structures and therefore the number of electrons they contain can be precisely controlled; a quantum dot can have anything from a single electron to a collection of several thousands. The physics of quantum dots shows many parallels with the behaviour of naturally occurring quantum systems in atomic and nuclear physics. As in an atom, the energy levels in a quantum dot become quantised due to the confinement of electrons. Unlike atoms however, quantum dots can be easily connected to electrodes and are therefore excellent tools for studying atomic-like properties. This new book presents the latest research developments in the world. |
Accelerate student learning with the perfect blend of content and problem-solving strategies! Physics: Principles and Problems offers integrated support, abundant opportunities for problem solving, and a variety of realistic applications. The program has a balance of good conceptual presentation with a strong problem-solving strand.

Built from the ground up on our new understanding of how students learn, Randall Knight's introductory university physics textbook leads students to a deeper understanding of the concepts and more proficient problem-solving skills. This authoritative text provides effective learning strategies and in-depth instruction to better guide students around the misconceptions and preconceptions they often bring to the course.
The superior problem-solving pedagogy of Physics for Scientists and Engineers uses a detailed, methodical approach that sequentially builds students' skills and confidence so they are better equipped to tackle more complex problems. Knight combines rigorous quantitative coverage with a descriptive, inductive approach that leads to a deeper student understanding of the core concepts. Pictorial, graphical, algebraic, and descriptive representations for each concept are skillfully combined to provide a resource that students with different learning styles can readily grasp. The research-proven media package features MasteringPhysics™, an online student tutorial and assignable homework program that helps students develop problem-solving skills and lets instructors know where their students are having trouble.
| Author(s) : Raymond A. Serway Publisher : Brooks Cole Date : 2004 Pages : 648 Format : PDF ISBN-10 : 0534493394 This text presents an introduction to relativity, quantum mechanics, and statistical physics as well as applications of these theories to molecular physics, condensed matter physics, nuclear physics, particle physics, and cosmology. Writing in a student-friendly and accessible manner, the authors strike the perfect balance, mixing relevant applications (many new to this edition) with the appropriate level of theory. A new Web-based simulation software package, QMTools, complements the text and provides modeling tools to help students visualize abstract concepts. Icons are provided throughout the text to highlight areas in which this software can enhance understanding. |
| Author(s) : W.N. Cottingham Publisher : Cambridge University Press Date : 2001 Pages : 271 Format : PDF ISBN-10 : 0521657334 This introduction to nuclear physics provides an excellent basis for a core undergraduate course in this area. The authors show how simple models can provide an understanding of the properties of nuclei, both in their ground and excited states, and of the nature of nuclear reactions. They include chapters on nuclear fission, its application in nuclear power reactors, the role of nuclear physics in energy production and nucleosynthesis in stars. This new edition contains several additional topics: muon-catalyzed fusion, the nuclear and neutrino physics of supernovae, neutrino mass and neutrino oscillations, and the biological effects of radiation. A knowledge of basic quantum mechanics and special relativity is assumed. Each chapter ends with a set of problems accompanied by outline solutions. |

This book presents an in-depth approach to concrete ingredients and their relationships to concrete by discussing their properties, pertinent test methods, specifications, proper use and selection, and solutions to problems in practice. The approach is practice oriented, and the book assists in the improved application of concrete through a thorough understanding of its ingredients. This is aided by the discussion of certain fundamental aspects and relationships in quantitative forms, and by also presenting the interpretation of research and experience. An extensive bibliography is included. The book is a current, organized summary of knowledge concerning concrete-making materials, which will enable the engineer/user to make the best possible product using these materials.
| Author(s) : Konstadinos G. Goulias Publisher : CRC Date : 2002 Pages : 428 Format : PDF ISBN-10 : 0849302730 Transportation engineering and transportation planning are two sides of the same coin aiming at the design of an efficient infrastructure and service to meet the growing needs for accessibility and mobility. Many well-designed transport systems that meet these needs are based on a solid understanding of human behavior. Since transportation systems are the backbone connecting the vital parts of a city, in-depth understanding of human nature is essential to the planning, design, and operational analysis of transportation systems. With contributions by transportation experts from around the world, Transportation Systems Planning: Methods and Applications compiles engineering data and methods for solving problems in the planning, design, construction, and operation of various transportation modes into one source. |
