W...y | 2011-09-27 | ISBN: 047075012X | 724 pages | PDF | 75,6 MB


This fourth edition of the bestselling Spacecraft Systems Engineering title provides the reader with comprehensive coverage of the design of spacecraft and the implementation of space missions, across a wide spectrum of space applications and space science. The text has been thoroughly revised and updated, with each chapter authored by a recognized expert in the field. Three chapters – Ground Segment, Product Assurance and Spacecraft System Engineering – have been rewritten, and the topic of Assembly, Integration and Verification has been introduced as a new chapter, filling a gap in previous editions.
This edition addresses ‘front-end system-level issues’ such as environment, mission analysis and system engineering, but also progresses to a detailed examination of subsystem elements which represents the core of spacecraft design. This includes mechanical, electrical and thermal aspects, as well as propulsion and control. This quantitative treatment is supplemented by an emphasis on the interactions between elements, which deeply influences the process of spacecraft design.

Adopted on courses worldwide, Spacecraft Systems Engineering is already widely respected by students, researchers and practising engineers in the space engineering sector. It provides a valuable resource for practitioners in a wide spectrum of disciplines, including system and subsystem engineers, spacecraft equipment designers, spacecraft operators, space scientists and those involved in related sectors such as space insurance.

In summary, this is an outstanding resource for aerospace engineering students, and all those involved in the technical aspects of design and engineering in the space sector.

The Art Of Electronics Paul Horowitz

Paul Horowitz - The Art of Electronics
Publisher: Cambridge University Press | 1125 pages | July 28, 1989 | ISBN-10: 0521370957 | PDF | 27.5MB
This is the thoroughly revised and updated Second Edition of the hugely successful The Art of Electronics. Widely accepted as the single, authoritative text and reference on electronic circuit design, both analog and digital, this book has sold over 120,000 copies, and has been translated into eight languages.
This book revolutionized the teaching of electronics by emphasizing the methods actually used by circuit designers--a combination of some basic laws, rules of thumb, and a large bag of tricks. The result is a largely nonmathematical treatment that encourages circuit intuition, brain storming, and simplified calculations of circuit values and performance. This completely new edition responds to the breakneck pace of change in electronics with totally rewritten chapters on microcomputers and microprocessors, substantially revised chapters on digital electronics, on op-amps and precision design, and on construction techniques. Every table has been revised, and many new ones have been added. The new Art of Electronics retains the feeling of informality and easy access that made the first edition so successful and popular.

Oracle E-Business Suite


What Is Oracle E-Business Suite?
Oracle E-Business Suite is a software package that allows organizations to manage key business processes; it is known on the market by various names such as Oracle Enterprise Resource Planning (ERP), Oracle Apps, Oracle Applications, Oracle Financials, e-Biz and EBS (E-Business Suite). In this book we refer to it as either E-Business Suite, or Oracle Applications. In the past, it was a common practice for businesses and organizations to develop in-house software to automate their business processes. Most of the software that was developed in-house largely matched the precise needs of the business. However, the fundamental business flows and processes such as accounting, procurement, human resource/employee management, and order management are based on common principles across all organizations. For example, most organizations require a system to make purchases from suppliers and a system to make payments to the suppliers, events known as transactions that need to be accounted for in the financial reporting. Enterprise Resource Planning (ERP) software prepackages different types of these functionalities into out-of-the-box software package, so that customers who purchase such software packages do not have to develop the same software applications time and again.Product FamiliesOracle E-Business Suite is a product offering that covers almost all of the business flows widely used in most organizations. Businesses can implement as many modules as necessary due to the modular but still integrated nature of the E-Business Suite architecture. This allows unified information to be available across the enterprise; it also reduces information technology (IT) expenses and helps run business more efficiently.On the contrary, managing heterogeneous software solutions developed in-house that use different systems and technologies can be extremely costly and complex. Any time you update one system, you must go back and review all the integration points and potentially update the interfaces between the systems. Oracle E-Business Suite is engineered to work as an integrated system on a common IT infrastructure.
You can directly pass information from one application to another without incurring ncremental integration costs.
The product offering in E-Business Suite is organized into product families.
Some of the key product families are as follows:
  • Financials
  • Procurement
  • Customer Relationship Management (CRM)
  • Project Management
  • Supply Chain Planning and Management
  • Discrete Manufacturing
  • Process Manufacturing
  • Order Management
  • Human Resources Management System (HRMS)
  • Applications Technology
