ABAQUS is a general purpose finite element analysis program which is widely used to analyses mechanICAl, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at the mechanICAl Engineering at Glasgow Universtity. The software which can transfer data from Abaqus into a Matlab readable environment has been developed as a part of a research program in Constraint Estimation in Fracture Mechanics. This research program was funded by a grant from the Defence Research Agency through Prof. J. Sumpter.

This book is about the management of business processes. This is certainly not a new topic. Since the beginning of the Industrial Revolution, it has been written about from every possible point of view—economic, sociological, psychological, accountancy, mechanICAl engineering and business administration. In this book, we examine the management of business processes from the perspective of computing, or—to put it more broadly—of information technology. The reason is that information technology has made huge leaps forward in recent years, resulting in the creation of completely new ways of organizing business processes. The development of generic software packages for managing business processes—so-called workflow management systems (WFMS)—is particularly important in this respect.

The widespread use of embedded systems mandates the development of industrial software design methods, i.e. computer-aided design and engineering of embedded applications using formal models (frameworks) and standardized prefabricated components, much in the same way as in other mature areas of engineering such as mechanICAl engineering and electronics. These guidelines have been used to develop Component-based Design of Software for Embedded Systems (COMDES). The paper gives an overview of the COMDES framework, followed by a presentation of a generic component types, such as function blocks, activities and function units. The execution of function units is discussed in the context of a newly developed execution model, i.e. timed-multitasking, which has been extended to distributed embedded systems.

C 開(kāi)發(fā)的有限元軟件,界面還可以,不錯(cuò),可以試試。 FElt is a free system for introductory level finite element analysis. It is primarily intended as a teaching tool for introductory type courses in finite elements - probably in the mechanICAl/structural/civil fields. In a command line environment, FElt uses an intuitive, straightforward input syntax to describe problems. It also includes a graphical user interface for workstations that allows the user to set-up, solve and post-process the problem in a single CAD-like environment.

Modern, large scale, display systems are migrating from traditional technologies such as incandescent, fluorescent and mechanICAl to sophisticated products based on LEDs. LED displays offer power savings and a superior visual experience in a range of products from programmable signage to large-scale video displays and commercial installations.

The mature CMOS fabrication processes are available in many IC foundries. It is cost-effective to leverage the existing CMOS fabrication technologies to implement MEMS devices. On the other hand, the MEMS devices could also add values to the IC industry as the Moore’s law reaching its limit. The CMOS MEMS could play a key role to bridge the gap between the CMOS and MEMS technologies. The CMOS MEMS also offers the advantage of monolithic integration of ICs and micro mechanICAl components.

For more than three decades, Micro Electro mechanICAl Systems (MEMS) have steadily transitioned out of research labs and into production forming a more than $10 billion market [1]. MEMS devices such as accelerometers, pressure sensors and microphones, to name a few, have seen immense utilization, particularly in the consumer electronics market, because of their compact sizes and minute power consumptions. In addition, these devices benefit from batch fabrication, which has enabled year-over-year reductions in cost [2]. In recent years,
