el-jardali and fadllallah provide an excellent summary of the many dimensions of knowledge use, and the breath of issues and activities that must be considered if knowledge is to be put into practice. however, reliance on a continuum (rather than a cyclical, multidirectional, systems) model creates a number of limitations, particularly when promoting evidence-informed action in the areas of hea...

This paper introduces the concept of polymorphic electronics (polytronics) –referring to electronics with superimposed built-in functionality. A function change does not require switches/reconfiguration as in traditional approaches. Instead, the change comes from modifications in the characteristics of devices involved in the circuit, in response to controls such as temperature, power supply vo...

This paper investigates the causal effect of pedestrian environments on walking behavior and focuses on the issue of research design. The paper differentiates between two types of research designs: treatment-based and traveler-based. The first approach emphasizes the variation of the treatment (pedestrian environments), and generally compares distinct neighborhoods, such as urban vs. suburban o...

Motion is ubiquitous in the physical world, yet its study is much less developed than that of another common physical modality, namely shape. While we have several standardized mathematical shape descriptions, and even entire disciplines devoted to that area–such as Computer-Aided Geometric Design (CAGD)—the state of formal motion descriptions is still in flux. This in part because motion descr...

Purpose of this paper is defining a framework for the “Warfighter-Centered Design” (WCD) of new concepts for naval combat systems. This framework explicitly takes into account the business value of WCD with respect to safety, optimal manning and reduced lifecycle costs. WCD improves safety because lack-of usability can lead to serious consequences; the analysis of the accident of USS Vincennes ...

Synchronous hardware design is facing significant challenges as we push for higher clock speeds and more complex chips. Aside from the incredible task of optimizing designs year after year, physical properties of circuits at the current scale and speed are becoming major roadblocks. For example, skew associated with high-fanout clock signals put a great burden the designer by increasing design ...

the industrial design is a two or three-dimensional aesthetic creation related to industrial products. according to the definition of the iranian law, for the realization of the legal protection of industrial designs there are three necessary components: combine lines or colors, runs on industrial products and change product appearance. in iran, only the registered designs are supported. while ...

-Emulation of CMS 1 systems is an interesting approach to complete the validation of new digital control unit and to perform the diagnosis tasks. However to be efficient, the emulator have to run in real time in order to reproduce exactly the physical process functioning. This paper describes the design of an Autonomous Emulator employing the system-level design methodology developed at CECS-UC...
