The Method Framework for Engineering System Architectures

0 nhận xét



One of the biggest sources of pain in system development is "system integration and test." This is frequently where projects sailing along with all-green progress reports and Earned Value Management System status summaries start to see these indicators increasingly turn to yellow and then to red. Projects that were thought to be 80 percent complete may be found to still have another 120 percent to go, increasing the relative costs of integration and test from 20 percent of the total to 120/200 = 60 percent of the total.
Managers often look at this 60 percent figure and say, "We need to find a way to speed up integration and test," and invest in test tools to make testing go faster. But this is not the root cause of the cost escalation. That happened a lot earlier in the definition and validation (or more often the lack of these) of the system's architecture. Components that were supposed to fit together did not. Unsuspected features in commercial off-the-shelf (COTS) products were found to be incompatible, with no way to fix them and little vendor interest in doing anything about the problems. Nominal-case tests worked beautifully but the more frequent off-nominal cases led to system failures. Readiness tests for safety and security certification were unacceptable. Defect fixes caused regression tests to fail due to unanticipated side effects. Required response times were impossible to meet. And award fees for on-time delivery and expected career promotions faded away.Tải miễn phí sách này tại đây

Analog and Digital Circuits for Electronic Control System Applications: Using the TI MSP430 Microcontroller

0 nhận xét



Provides a clearly written, real-world source of basic
information and circuit designs for up-to-date analog/digital control system design techniques using microcontrollers!
Today's control system designers face an ever-increasing "need for speed" and accuracy in their system measurements and computations. New design approaches using microcontrollers and DSP are emerging, and designers must understand these new approaches, the tools available, and how best to apply them.
This practical text covers the latest techniques in microcontroller-based control system design, making use of the popular MSP430 microcontroller from Texas Instruments.
The book covers all the circuits of the system, including:
� Sensors and their output signals
� Design and application of signal conditioning circuits
� A-to-D and D-to-A circuit design
� Operation and application of the powerful and popular TI MSP430 microcontroller
� Data transmission circuits
� System power control circuitry
Written by an experienced microcontroller engineer and textbook author, the book is lavishly illustrated and includes numerous specific circuit design examples, including a fully tested and documented hands-on project using the MSP430 that makes use of the principles described. For students, engineers, technicians, and hobbyists, this practical text provides the answers you need to design modern control systems quickly and easily.
* Seasoned Texas Instruments designer provides a ground-up perspective on embedded control systems
* Pedagogical style provides a self-learning approach with examples, quizzes and review features
* CD-ROM contains source code and more!

The Black Sea Environment (The Handbook of Environmental Chemistry)

0 nhận xét



This book presents a systematic description of the knowledge accumulated on the physical oceanography, marine chemistry and pollution, marine biology and geology, meteorology and hydrology of the Black Sea. It presents the principal characteristic features of the environmental conditions of the sea and their changes in the second half of the 20th century. At present, the principal problems of the Black Sea are related to the estimation of the intensity of the chemical pollution of the sea and its impact upon the biota. Special attention is given to the socioeconomic, legal, and political issues in the Black Sea region. This publication is based on numerous observational data collected by the authors of the various chapters during sea expeditions, on the archive data of several Russian and Ukrainian oceanographic institutions, as well as on a large body of scientific literature, mainly published in Russian editions. This book is aimed at specialists concerned with research in the various fields of physical oceanography, marine chemistry, pollution studies, and biology whose work involves solving a wide range of problems from regional climate to mesoscale processes, and who use a variety of methods from remote sensing of the seas to numerical and laboratory modeling.
