For companies, the improvement of the recyclability performance of their newly designed products is becoming an integral part of product development process. The concept of environmental conscious design (ECD) has been adopted to assist the environmental performance of the products at the early stage of designing. This new trend requires that the design strategies need to be modi"ed by integrat...

Designers and engineers need better tools methods to create highly repairable products. Design for disassembly reassembly is an important product related design feature that can enhance repair. In a product, the components fail most often should be easily accessible repair or replacement. This paper describes development of method visually map showing different routes towards target components....

A new spatial-domain Blur Equalization Technique (BET) is presented. BET is based on Depth-from-Defocus (DFD) technique. It relies on equalizing the blur or defocus of two different images recorded with different camera parameters. Also, BET facilitates modeling of images locally by higher order polynomials with lower series truncation errors. The accuracy of BET is further enhanced by discardi...

Objectives. The effects of the traditional formula Dahuang Fuzi Decoction (DFD) on chronic aristolochic acid nephropathy (AAN) in mice and its underlying mechanisms were studied. Methods. Mice were randomly divided into the following six groups: the control group, the model group (AAN), the saline-treated group (AAN + vehicle), the normal dose DFD-treated group (AAN + NDFD), the high dose DFD-t...

Construction waste management is becoming an emerging issue in light of the massive increase construction activities developing economies as part their rapid economic growth. The gradual tightening building regulations towards energy consumption creates need to decrease materials and components during construction, one proposed ways achieve it reuse. can be initially designed for disassembly (D...

Decision-making methodologies for evaluating a product’s end-of-life options have become a significant area of research. Extensive work has been carried out in the area of product recovery, e.g. module-based disassemblability, reverse logistics, remanufacturing, material recyclability, among others. Some of these methods use graphical representations in the form of disassembly trees and/or netw...

In the current recycling system of end-of-life (EoL) appliances, which is based on shredding, alloying elements tend to end up in the scrap of base metals. The uncontrolled mixing of alloying elements contaminates secondary metals and calls for dilution with primary metals. Active disassembling fastener (ADF) is a design for disassembly (DfD) technology that is expected to solve this problem by...

Abstract The construction industry is responsible for a significant portion of the solid waste that industrialised nations dispose each year. One reason this low rates reuse and recycling, largely due to difficulties in deconstructing buildings an inability easily separate materials components. If were designed facilitate deconstruction easier separation parts, then future material component re...

A green design for assembly model is presented to integrate design evaluation and assembly and disassembly sequence planning by evaluating the three activities in one integrated model. For an assembled product, an assembly sequence planning model is required for assembling the product at the start of the product life cycle. A disassembly sequence planning model is needed for disassembling the p...
