SIDEBAR: The future of DFD methodologies For reasons of cost, performance, power, and miniaturization, many electronic systems that once consisted of several printed circuit boards are now manufactured as a single semiconductor device. As a result of this complexity, previously accessible system signals can no longer be observed, and the process of isolating and analyzing silicon problems has b...

Design process is an important stage in product development. Information model is a useful tool in analyzing and improving complex design process. It can facilitate to rebuild the process through visualizing information flow. Owing to the disadvantages of describing complex design process with data flow diagram (DFD), the extended DFD with powerful description ability is put forward. After the ...

In this paper, SNR scalable representations of video signals are studied. The investigated codecs are well suited for communications applications because they are all based on backward motion-compensated predictive coding, which provides the necessary low-delay property. In a Very-Low Bit Rate context (VLBR), the Matching Pursuits signal representation algorithm is used to represent the Displac...

However excellent a product may be environmentally, it would not come into wide use in the economy to realize its environmental load reducing potential unless it is also economically affordable. Life-cycle costing (LCC) is a tool to assess the cost of a product over its entire life cycle, and can be regarded as an economic counterpart of LCA. A combined use of LCA and LCC would be imperative fo...

Abstract Scan chains take as much as 30% of the silicon area [1], while scan chain failure accounts for almost 50% of chip failure [2]. Conventional logic diagnosis techniques abort the di...

The investigated codecs are well suited for communications applications because they are all based on backward motion-compensated predictive coding, which provides the necessary low-delay property. In a very-low bit rate context (VLBR), the matching pursuits (MP) signal representation algorithm is used to represent the di...

Depth from defocus (DfD) and stereo matching are two most studied passive depth sensing schemes. The techniques are essentially complementary: DfD can robustly handle repetitive textures that are problematic for stereo matching whereas stereo matching is insensitive to defocus blurs and can handle large depth range. In this paper, we present a unified learning-based technique to conduct hybrid ...

Selective disassembly involves separating a selected set of components from an assembly. Applications for selective disassembly include de-manufacturing (maintenance and recycling), and assembling. This paper presents a new methodology for performing design for selective disassembly analysis on the CAD model of an assembly. The methodology involves the following three steps: (i) identifying the...
