Signals and systems is an important aspect of radio science. The recent progress of the research activities of signals and systems in China is reviewed in this paper. It covers the most advanced and important developments during years of 1998~2001. The review is based on the following categories: wideband CDMA, software radio, digital audio broadcasting technologies, information processing, rad...

This is Part I of a sequence of two papers on Contract-Based Design (CBD). It is intended to: • Introduce the concepts underlying CBD; • Present the challenges facing facing designers of large-scale complex systems today; • Review the design methodologies so far used to address these challenges and show how contracts can be used in all these approaches to enhance their applicability and the qua...

In the fast-paced semiconductor industry, time to market means everything. Accommodating the shortened design cycles, however, is hampered by the ever-increasing design complexity. In addition, the continual drive to achieve higher performance (speed, area, power) has fueled the introduction of new manufacturing processes. Existing integrated circuit design methodologies, such as standard-cells...

Approach and avoidance are two major types of behavioral responses when consumers encounter interferences caused by online advertising. This paper argues that approach-avoidance is not the only dimension from which researchers can examine behavioral responses toward online advertising. The inclusion of the active-passive behaviors dimension enriches the understanding of consumers’ coping strate...

Nowadays, in highly competitive global markets and constant pressure to reduce total costs, enterprises consider group technology and Supply Chain Management (SCM) accordingly and usually separately as the key elements for intra and inter facilities improvement. Simultaneous consideration of the elements of these two disciplines in an integrated design can result in higher efficiency and ...

III.1. Basic Model for the Operational Amplifier. The OPerational AMPlifier (OPAMP) is a key building block in analog integrated circuit design. The OPAMP is composed by several transistors and passive elements (resistors and capacitors) and arranged such that its low frequency voltage gain is very high; the dc gain of the OPAMP-741 is around 10 V/V (10 μV at the input give us 1 V at the output...

computer-integrated manufacturing (cim), technologies are presented as solutions tomanufacturing organizations, which need to perform well in all customer-related dimensionssimultaneously. in the literature, cim technologies providing such benefits as more frequentproduction changes, reduced inventory level, improved ability of producing complex parts with ahigh degree of accuracy and repeatabi...

the synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. to provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...
