The importance of plastic gears for modern industry is growing every year. The engineer sizing plastic gears has a very difficult task. There is no international standard available for the strength analysis. The only method publicly accepted is the German guideline VDI2545. In addition to a lack of calculation methods there is a need for measuring material properties. This paper shall give an o...

T he issue of mold contamination has drawn the national and international spotlight on the heels of publicity about prominent situations , such as a hotly contended link between mold and severe illness—and one death—in 10 Ohio infants in 1993 and 1994; a major 2001 insurance battle over the moldy Dripping Springs, Texas, house of Melinda Ballard and her family; the mushrooming mold infestations...

This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...

Three dimensional models can be a valuable tool for surgeons as they develop surgical plans and medical fellows learn about complex cases. In particular, 3D play an important role in the field of cardiology, where congenital heart diseases occur. While many printers provide anatomically correct detailed models, existing printing materials fail to replicate myocardial tissue properties extremely...

In order to remain competitive with respect to low-cost overseas markets, domestic moldmakers will have to increase the productivity of their engineers and maintain high quality standard, while dealing with the problem of an aging workforce. To increase the competitiveness of the European automotive industry, the concept of and Integrated Design and Engineering Environment (IDEE) has been devel...

Mold is ubiquitous, and exposure to mold and its products of metabolism is unavoidable, whether indoors or outdoors. Mold can produce a variety of adverse health outcomes by four scientifically validated pathophysiologic mechanisms: hypersensitivity, toxicity, infection, and irritation. Some adverse health outcomes have been attributed to mold for which mechanisms of injury are not well defined...

The principle of achieving high strength and superior properties in metal alloys through the application of severe plastic deformation has been exploited in the metal processing industry for many decades. The High Pressure Torsion (HPT) process is one of the most promising techniques for imposing very high strains to a bulk solid without introducing a significant change in sample dimensions. Th...

In recent years, the demand for plastic products has increased, and along with deepening of academics, mass production, weight reduction, high precision are progressing. fields design development production technology, there many issues related to quality assurance such as molding defects product strength. particular, in resin process, is a degree freedom shape mold structure, it an important i...

This paper deals with the development of accurate warpage prediction model for plastic injection molded parts using soft computing tools namely, artificial neural networks and support vector machines. For training, validating and testing of the warpage model, a number of MoldFlow (FE) analyses have been carried out using Taguchi’s orthogonal array in the design of experimental technique by cons...

BACKGROUND A large proportion of the plastic surgery literature is dedicated to the breast. It is one of the most common topics in our specialty, yet it is unclear which articles have been the most influential. The purpose of this study was to identify the top 100 most-cited articles on breast in the plastic surgery literature and examine the characteristics of each individual article. METHOD...
