The problem of voids and porosity has long plagued the dental technician. Many times an otherwise acceptable casting has had to be discarded because voids or porosities have developed within the casting. Because of numerous variables a technician often does not know the cause of the casting failure. Many investigators have studied variables that may affect the occurrence of voids and porosities...

This work describes the conception, development and application of a methodology for the production scheduling in foundries. It has two important and linked moments, which are the furnace scheduling and the molding machines scheduling. The challenge consists in determining an adequate sequencing of production orders in the molding lines, combining light weight with average and heavy pieces, in ...

Logic locking is a technique that has been proposed to protect outsourced IC designs from piracy and counterfeiting by untrusted foundries. A locked IC preserves the correct functionality only when a correct key is provided. Recently, the security of logic locking is threatened by a new attack called SAT attack, which can decipher the correct key of most logic locking techniques within a few ho...

The results of research on working conditions and labor safety assessment in foundries are presented. production factors with different types their impact injuries professional incidence workers considered. Recommendations to improve reduce foundry given.

In a previous paper (Turner, 1957) the results of a survey of the thermal environments in non-ferrous foundries were reported, reference was made to the index of heat stress proposed by Belding and Hatch (1955), and an indication was given of how this index could be used to evaluate the severity of the heat stress which might be encountered in foundries. A few observations were reported which s...

Due to recycling of metals, most foundries have considered themselves as a part of the green technology before the term “green’’ was even coined. But, actually, the foundry industry handles large quantities of processed waste materials and has the potential to emit a large quantity of carbon dioxide and other pollution in atmosphere. This immense pressure not only forcing foundry industries to ...

Due to increase in threats posed by offshore foundries, the companies outsourcing IPs are forced protect their designs from foundries. Few of IP piracy, counterfeiting and reverse engineering. To overcome these, logic encryption has been observed be a leading countermeasure against faced. It introduces extra gates design, known as key which hide functionality design unless correct keys fed them...
