Wireless Sensor Network (WSN) contains many low cost and low power sensor nodes (SNs), these nodes may fail to communicate with each other according to some reasons such as battery lifetime or uncontrolled events which will lead to partition the network and reduce the Quality of Service (QoS) as well as the reliability and efficiency of the whole network. The motivation of this paper is detecti...

An important aspect in recycling and reuse for environmentally conscious manufacturing is disassembly. Although disassembly systems contain the same basic elements as assembly system, the disassembly problem differs significantly from the assembly problem due to the fact that the incoming disassembly product is not controlled. In addition, complete dismantling of products is not necessarily req...

The assembly, stability, and timely disassembly of short interfering RNA (siRNA) nanocomplexes have the potential to affect the efficiency of siRNA delivery and gene silencing. As such, the design of new probes that can measure these properties without significantly perturbing the nanocomplexes or their environment may facilitate the study and further development of new siRNA nanocomplexes. Her...

perlite or pearl stone is a natural glass which has formed by rapid cooling of viscous lava or magma. perlite is mainly composed of silica, aluminum, potassium and sodium. in this experiment, perlite was used as a low-cost source of si and al to synthesis of sodalite zeolite using the alkaline hydrothermal treatment. a statistical taguchi design of experiments was employed to evaluate the effec...

We propose a depth-fused display (DFD) with enhanced viewing characteristics by hybridizing the depth-fusing technology with another three-dimensional display method such as multi-view or integral imaging method. With hybridization, the viewing angle and expressible depth range can be extended without changing the size of the volume of the system compared to the conventional DFD method. The pro...

A total of six fiber types, including four pure types (type I, IIA, IIX, and IIB) and two hybrid types (type IIAX and IIXB), were classified according to the expression of myosin heavy chain (MHC) isoforms by immunohistochemistry with MHC specific monoclonal antibodies. The comparison of the muscle fiber characteristics and pork quality between pork quality groups (DFD: dark, firm, and dry; PSE...

This work proposes a framework for transforming data flow diagrams (DFD) into UML artifacts. The framework is a systematic step-by-step approach that enables systems analysts and designers to achieve the transformation. Many existing legacy systems were designed using structured analysis and design methodology (SAD). Some of these legacy systems need to be re-designed and reproduced using objec...

In this paper, algorithms are presented in order to determine the best disassembly sequence for a sub-assembly and a system life-cycle model for disassembly-assembly line design. The main contribution consists in the determination of a sequence which has the minimal number of components to disassemble, taken into account several criteria: stability, the geometrical form, operations done in para...

Depth from defocus (DFD) is a 3D recovery method based on estimating the amount of defocus induced by finite lens apertures. Given two images with different camera settings, the problem is to measure the resulting differences in defocus across the image, and to estimate a depth based on these blur differences. Most methods assume that the scene depth map is locally smooth, and this leads to ina...
