2006 Aston Martin - A Guide.pdf

November 19, 2009 · Filed Under Aston Martin · Comment  · Tags: , , , ,

Taken from Aston MArtin The Present: The 21st Century has seen an astonishing change of pace at Aston Martin. With production during the final four years of the previous century running between 620 and 660 models a year, the year 2000 saw a huge jump to 1,029 units, 1,000 of which were the newly developed V12 powered DB7 Vantage.
Production rose by almost 50 per cent in 2001 to 1,506 cars. Again the lion’s share was of DB7 variants, but 204 Vanquish models helped make up the total. In 2003, Aston Martin created a sales record of nearly 1,600 cars and another record was created in the US with 500 cars sold representing 33% of production volume. Records were surpassed again in 2004.
Vanquish production also continues at Newport Pagnell, but now in the form of the fastest ever production Aston Martin – the Vanquish S, capable of over 200mph and offering the ultimate high performance Aston Martin. The Vanquish S has been designed to deliver even greater performance, complemented by subtle suspension and steering changes and a number of interior and external style revisions.
Newport Pagnell is also home to the Works Service department for development of customer-driven specialist projects and accident repair, as well as Heritage Operations, which restores older Aston Martin models.
The company’s new state of the art Gaydon facility begins a new chapter in Aston Martin’s history. As the new company headquarters, Gaydon will house production of the DB9 and V8 Vantage as well as all future Aston Martin models.
In 2005, Aston Martin returned to international motor sport with the DBR9 based on the road going DB9.

Nanotechnology: The Plastics of the 21st Century?.pdf

November 10, 2009 · Filed Under Engineering Physic · Comment  · Tags: ,

Taken from Preface: This report was prepared by Guy Carpenter & Company, Inc. in conjunction with Dr. Robert Blaunstein, National Director of Loss Control and Underwriting Manager for American Safety Insurance Company. Previously, Dr. Blaunstein was Managing Director and co-founder of Seneca Environmental Management (SEM), Vice President of Seneca Specialty Company and Vice President of Crum and Forster Specialty Insurance Company. While Assistant Professor of Physics at the University of Tennessee and consulting scientist to the Oak Ridge National Laboratory, Dr. Blaunstein conducted research, provided instruction and supervised doctoral students in the area of atomic and molecular radiation physics. A frequent lecturer and consultant to governmental and industrial leaders throughout the world, Dr. Blaunstein was a Public Health Service Fellow and member of the United States Chamber of Commerce, Environment Committee and is a member of the American Physical Society, The American Society of Testing and Materials, National Groundwater Association and the Sigma Xi Honorary Society. He received his Ph.D. in physics from the University of Tennessee and an M.S. degree in physics from Case Western Reserve University.

Fundamentals of Compressible Flow Mechanics.pdf

November 9, 2009 · Filed Under Mechanical & Industrial Engineering · Comment  · Tags: , ,

Taken from Preface: This book, Fundamentals of Compressible Flow, describes the fundamentals of compressible flow phenomena for engineers and others. This book is designed to replace the book(s) or instructor’s notes for the compressible flow in (mostly) undergraduate classes for engineering/science students. It is hoped that the book could be used as a reference book for people who have at least some knowledge of the basics of fundamental fluid mechanics, and basic science such as calculus, physics, etc. It is hoped that the computer program enclosed in the book will take on a life of its own and develop into an open content or source project.
The structure of this book is such that many of the chapters could be usable independently. For example, if you need information about, say, Fanno flow, you can read just chapter 9. I hope this makes the book easier to use as a reference manual. However, this manuscript is first and foremost a textbook, and secondly a reference manual only as a lucky coincidence.

Automating Manufacturing Systems with PLCs.pdf

Taken from PROGRAMMABLE LOGIC CONTROLLERS’s Introduction: Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution, the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s, and has become the most common choice for manufacturing controls.
PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer: Cost effective for controlling complex systems.
Flexible and can be reapplied to control other systems quickly and easily.
Computational abilities allow more sophisticated control.
Trouble shooting aids make programming easier and reduce downtime.
Reliable components make these likely to operate for years before failure.

Fundamentals of Die Casting Design.pdf

November 7, 2009 · Filed Under Mechanical & Industrial Engineering · Comment  · Tags: , , , ,

Taken from Abstract: Die-casting engineers have to compete not only with other die-casting companies, but also against other industries such as plastics, and composite materials. Clearly, the ”black art” approach, which has been an inseparable part of the engineer’s tools, is in need of being replaced by a scientific approach. Excuses that “science has not and never will work” need to be replaced with “science does work”. All technologies developed in recent years are described in a clear, simple manner in this book. All the errors of the old models and the violations of physical laws are shown. For example, the “common” pQ2 diagram violates many physical laws, such as the first and second laws of thermodynamics. Furthermore, the “common” pQ2 diagram produces trends that are the opposite of reality, which are described in this book.
The die casting engineer’s job is to produce maximum profits for the company.
In order to achieve this aim, the engineer must design high quality products at a minimum cost. Thus, understanding the economics of the die casting design and process are essential. These are described in mathematical form for the first time in this volume. Many new concepts and ideas are also introduced. For instance, how to minimize the scrap/cost due to the runner system, and what size of die casting machine is appropriate for a specific project.
The die-casting industry is undergoing a revolution, and this book is part of it. One reason (if one reason can describe the situation) companies such as Doehler Jorvis (the biggest die caster in the world) and Shelby are going bankrupt is that they do not know how to calculate and reduce their production costs. It is my hope that die-casters will turn such situations around by using the technologies presented in this book. I believe this is the only way to keep the die casting professionals and the industry itself, from being “left in the dust.”
