    As we learn software/hardware development tools and techniques, we can place them into the framework presented in this section. As illustrated in Figure , the development of a product follows an analysis-design-implementation-testing-deployment cycle.   The need for speed: Capturing today’s fashion consumer. Open interactive popup. Article (PDF -1MB) The traditional product-development model is too slow. To get started, we suggest taking a page from the book of agile technology development. Completely upending a well-oiled process is daunting and often meets resistance.

    Periodisation is a theoretical model that offers a framework for the planning and systematic variation of an athlete's training prescription. 1 Periodisation was originally developed to support the training process in track and field or similar sports in which there is a clear overall objective such as training tailored towards a major Cited by: Systems with Hysterisis: Analysis, Identification and Control using the Bouc-Wen Model offers an invaluable source of ideas, concepts and insights for engineers, researchers, lecturers and senior/ postgraduate students involved in the research, design and development of smart structures and related areas within civil and mechanical engineering.

    Structural Integrity Research of the Electric Power Research Institute presents the result of the mission of the Electric Power Research Institute to conduct research and development promoting the clean, safe, and economical generation of power by the utility industry. This book covers nuclear plant design, licensing, and regulation questions. Materials Forming and Machining: Research and Development publishes refereed, high quality articles with a special emphasis on research and development in forming materials, machining, and its applications. A large family of manufacturing processes are now involved in material formation, with plastic deformation and other techniques commonly.

This report presents the work performed by Lockheed Martin Engineering and Sciences (LMES) in support of the High Speed Research (HSR) Flexible Semispan Model (FSM) wind-tunnel test. The test was conducted in order to assess the aerodynamic and aeroelastic character of a flexible high speed civil transport wing.

In the case of the flexible high-speed civil transport (HSCT), the focus was on the high dynamic response over a very narrow Mach number range from to [5], for which it can be expected.

semi-span model test capability in the NASA Langley Research Center's National Transonic Facility. This capability is required for the testing of high-lift systems at flight Reynolds numbers.

This model estimates the performance limits of the system, and indicates the components which most limit the link performance. The capacity of typical high-speed link backplane channels is between 50 and Gb/s, which is much higher than 3 Gb/s data rates of currently deployed baseband Size: 4MB.

fostered a large research and development effort in high-speed chip I/O design. This work investigated improving the performance of both high-speed serial links and wider parallel buses. The results of this research are everywhere, and range from high-speed memory interfaces [1,2], and processor interfaces [3], to Gb/s serial links [4,5].

Chinese high-speed railway has developed very quickly and at a very large scale. However, many issues reagrding safety has not been addressed. This book considers the issue from the perspective of a system. A train operation control system structure is put forward in order to ensure safety.

This paper presents a new solution procedure for an integrated thermo-dynamic spindle model and validation results. Based on the model presented in Part 1 of this paper, a computer program has been developed to generate comprehensive solutions for high speed spindle-bearing systems, such as bearing stiffness, contact load and temperature, spindle dynamic characteristics and response Cited by: The status and some recent developments in computational modeling of flexible multibody systems are summarized.

Discussion focuses on a number of aspects of flexible multibody dynamics including: modeling of the flexible components, constraint modeling, solution techniques, control strategies, coupled problems, design, and experimental by: Balancing Techniques for High-speed Flexible Rotors A.

He focuses on the challenges of testing high-speed digital devices especially in the area of test fixture design, signal integrity, jitter testing and focus calibration. He joined Agilent Technologies in There are two types of bicoherence analysis, the first is Fourier based and the other is wavelet based; the wavelet based option will be used in this research.

A formal definition of wavelet bicoherence is provided in Section 3 of this work. Bispec- tral analysis is applied to a wide variety of nonlinear systems.
