Metric Edition - Crane Technical Paper No. 410 (TP-410) is the quintessential guide to understanding the flow of fluid through valves, pipe and fittings, enabling you to select the correct equipment for your piping system. Originally developed in 1942, the latest edition of Crane TP-410 serves as an indispensable technical resource for specifying engineers, designers and engineering students. TP-410 is authored by Crane Valve Group (CVG), one of the world's leading suppliers of valve products and services....
Woven Fabrics are fl exible, porous materials used for clothing, interior and technical
applications. Regarding their construction they posses different properties which are
achieved to satisfy project demands for specifi c end-use. If woven fabrics are to be engineered
to fi t desired properties with minimum production costs, then the relationship between their
constructional parameters and their properties must be fi rst quantitatively established.

Chapter 8 - Exergy: A measure of work potential. In this chapter, we examine the performance of engineering devices in light of the second law of thermodynamics. We start our discussions with the introduction of exergy (also called availability), which is the maximum useful work that could be obtained from the system at a given state in a specified environment, and we continue with the reversible work, which is the maximum useful work that can be obtained as a system undergoes a process between two specified states.
Chapter 8 - Exergy: A measure of work potential. After studying this chapter you will be able to: Examine the performance of engineering devices in light of the second law of thermodynamics; define exergy (also called availability), which is the maximum useful work that could be obtained from the system at a given state in a specified environment; define reversible work, which is the maximum useful work that can be obtained as a system undergoes a process between two specified states;...
Chapter 12 – Dependability and security specification. The objective of this chapter is to explain how to specify functional and non-functional dependability and security requirements. When you have read this chapter, you will: understand how a risk-driven approach can be used for identifying and analyzing safety, reliability, and security requirements; understand how fault trees can be used to help analyze risks and derive safety requirements;...
During my experience of research for the last 25 years, I have felt the need for a text book
written specifi cally for Design Engineers and Materials Scientists. Although there have
been a number of excellent books written on the subject, they are now either out of date or
fundamental in nature. There is a growing need to adopt advanced techniques / technologies
to meet the ever increasing demand for high effi ciency in existing engines and to develop
modern gas turbines for strategic and special applications....
Jess is a rule engine for the Java platform. To use it, you specify logic in the form of
rules using one of two formats: the Jess rule language (prefered) or r XML . You also
provide some of your own data for the rules to operate on. When you run the rule
engine, your rules are carried out. Rules can create new data, or they can do anything
that the Java programming language can do.
Some basic concepts of analogue signals are introduced in this section. You will learn the basic functions of an analogue electronic system, viz. transformation and generation of signals of continuous nature. Here, signal transformation refers to all kinds of manipulation such as filtering (selecting signals of a certain range of frequencies) and amplification (enlarging the magnitude of a signal). Signal generation in the context of analogue electronics can be taken to mean the construction of a signal with a specified waveform, as in the case of a sinusoidal wave generator.
Sensitivity Analysis Sensitivity analysis allows you to analyze how various measured quantities (parameters) vary when a model dimension or an independent model parameter is varied within a specified range. The result is a graph for each selected parameter showing the value of the parameter as a function of the dimension. This provides for understanding exactly how geometric changes to your model will affect your engineering goals or specifications.
The title of this book was specifi cally chosen to encompass all the chapters presented in the
book. Solar collectors and panels have become household and industrial items being used for
power production, heating, cooling and are even being used for outer space research because
of their environmentally friendly nature.
The chapter on uniform flow in open channels is basic knowledge required for all hydraulics students. In this chapter, we shall assume the flow to be uniform, unless specified otherwise. This chapter guides students how to determine the rate of discharge,
the depth of flow, and the velocity. The slope of the bed and the cross-sectional area remain constant over the given length of the channel under the uniform-flow conditions. The same holds for the computation of the most economical cross section when designing the channel.

Analog circuit design imposes many issues and challenges to guarantee the development
of successful applications. For instance, the accomplishment of target specifi cations
requires the highest experience of analog designers along with their creativity
and ingenuity to deal with trade-off s and to discover the obscure interactions among
design parameters. From this point of view, analog circuit design is considered a kind
hypothesis may be written as follows: If a design limit of creep strain 8D is specified, it is predicted that the creep strain 8D will be reached when
i = l L1
where tt = time of exposure at the rth combination of stress level and temperature L1 = time required to produce creep strain 8D if entire exposure were held constant at the /th combination of stress level and temperature Stress rupture may also be predicted by (18.78) if the L1 values correspond to stress rupture.

2 structures, including pressurized cabins and pressure vessels, relatively large amounts of damage may be contained by providing tear straps or stiffeners. There is usually a high probability of damage detection for a class 2 structure because of fuel or pressure leakage, that is, "leak-before-break" design is characteristic of class 2 structures.
Project planning involves answering two questions. Answering
the first question, “What do we need to do?” is generally called
requirements gathering. Answering the second question, “How
will we do it?” is called designing or specifying (see Figure 3-1).
A requirement is a carefully written description of a criterion
that the work is expected to satisfy. (For example, a
requirement for cooking a meal might be to make inexpensive
food that is tasty and nutritious.) Good requirements are easy to
understand and hard to misinterpret.
