The ablation and oxidation of ZrB₂-based ultra high temperature ceramic (UHTC) composites containing 10%, 15% and 30% v/v SiC were tested under different heat fluxes in a high frequency plasma wind tunnel. Performance was significantly affected by the surface temperature, which was strongly dependent on the composition. Composites containing 10% SiC showed the highest surface temperature (>2300...

We study a sequential all-pay auction where heterogeneous contestants are privately informed about a parameter (ability) that a¤ects their cost of e¤ort. In the case of two contestants, contestant 1 (the …rst mover) makes an e¤ort in the …rst period, while contestant 2 (the second mover) observes the e¤ort of contestant 1 and then makes an e¤ort in the second period. Contestant 2 wins the conte...

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 ...

process mediated by or involving microorganisms in which a product of economic value is obtained is called fermentation (Casida, Jr., 1968). The terms industrial microbiology and fermentation are virtually synonymous in their scope, objectives and activities. The microbial product may be microbial cells (living or dead), microbial biomass, and components of microbial cells, intracellular or ext...

This paper aims to contribute to understanding the dynamics of industrial symbiosis. More specifically, we focus on the dynamics of anchoring as they can be observed in the Chinese context of eco-industrial development. We define anchoring as those activities that (typically local) actors perform to create local physical and institutional conditions conducive to the emergence and further develo...

The exchange of wastes, by-products, and energy among closely situated firms is one of the distinctive features of the applications of industrial ecological principles.This at= ticle examines the industrial district at Kalundborg, Denmark, often labeled as an “industrial ecosystem” or “industrial symbiosis” because ofthe many links among the firms.The forces that led to its evolution and to the...

In this study, we propose an intelligent automated disassembly cell for online (real time) selective disassembly. The cell is composed of an industrial robotic manipulator, a camera, range sensing and component segmentation visual algorithms. The cell prototype allows for robotic sensory-driven disassembly under uncertainty. An online genetic algorithm model for selective disassembly is also pr...
