economic considerations, such as the rising cost of water slipply and effluent treatment, shortage of water created by increased demand, and tighter legal control. Dyehouse effluents contain a wide range of impurities which may be organic or inorganic, soluble, colloidal or suspended. These impurities will limit the suitability of the effluent for immediate recycling to varying degrees dependin...

Cook County Hospital, like many hospitals in the U.S. and worldwide, is pursuing a developing strategy to combat healthcare-associated infections (HAIs). Annually, the human toll in the U.S. is approximately two million infected, of which over 100,000 die. An interdisciplinary team of researchers from Georgia Tech, the CDC, and Cook County Hospital, with backgrounds in engineering, economics an...

Consumer demand for smaller and lighter products in wiresless application with maximum functionality had drive the semiconductor industries toward the developement of 3-dimensional stacked die. One of the key technology is relies on die stacking process. A suitable bonding condition and material set are essential to achieve required reliability performance. This study is to relate the effects o...

In an earlier paper ( I ) we have shown that the poison of closed duodenal loops, which is responsible for the intoxication in that condition, is not absorbed by the mucosa of the unobstructed gut. We also tested the absorption of the same toxic fluid when introduced into recently isolated duodenal loops, and found that the dogs whose closed loops contain a double lethal dose of duodenal loop p...

sheet metal components design and manufacture need a great deal of experience and know-how. strip layout design is usually done with trial and error until best design for strip layout is finally achieved. knowledge for the system is formulated from plasticity theories, experimental results, and the empirical knowledge of field experts. in this paper, an algorithm which can automatically design ...

in this paper, based on the slab method of analysis, a novel and general approach isdeveloped for studying the radial forging process with curved profile dies. the presented approachis not only more general with respect to previous studies, but it is also easier to understand and useand can be efficiently used for optimization of the die profile depending on the forging geometryand conditions. ...

the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

1 Basic Probability Probability theory begins with three basic components. The set of all possible outcomes, denoted Ω. The collection of all sets of outcomes (events), denoted A. And a probability measure P. Specification of the triple (Ω,A,P) defines the probability space which models a real-world measurement or experimental process. Example 1 Ω = {all outcomes of the roll of a die} = {1, 2, ...

In the article the changes associated with construction of machines used in die and die-less sheet metal forming have been presented. The selected future directions of development in new technologies and machines for sheet metal forming taking into account modern blank holding systems in the process of deep drawing have been indicated. Also the tendencies in introduction of new technologies and...
