Previous studies point out a large (untapped) potential for energy efficiency in industry through the adoption of energy management practices. The aim of this paper is to describe and analyze energy management practices in two different Swedish energyintensive industries: the pulp and paper industry and the foundry industry. The results show that one third of the studied mills and about two fif...

Iron foundries have been identified as dioxin sources in previous field investigations. Similar formation mechanisms between dioxins and unintentional polychlorinated naphthalenes (PCNs) have led us to speculate that iron foundries are also potential PCN sources. In this study, PCNs in stack gas and fly ash samples representing atmospheric and residue emissions from 13 typical iron foundry plan...

Foundries and the Dawn of an Open IP Era T oday’s IC industry continues down a path of dis-integration it has followed for more than a decade—shifting from a vertical structure to a horizontal one, with many specialized and focused segments comprising the industry value chain. This dis-integration facilitates the growth of system-on-chip (SOC) technology and enhances operational efficiency by s...

BACKGROUND Iron and steel foundry workers are exposed to various toxic and carcinogenic substances including crystalline silica, polycyclic aromatic hydrocarbons, and arsenic. Studies have been conducted on lung cancer in iron and steel founding workers and the concentration of crystalline silica in foundries; however, the concentration of crystalline silica and cases of lung cancer in a single...

Several technical papers are available on casting defects in the literature. However, quality costs in steel foundries are still mainly due to the rework and scrap related to casting anomalies, which are not acceptable to customers. In order to minimize the castings which do not meet the customer acceptance specifications, it is not only necessary to identify the process parameters related to t...

Surveys of the prevalence and social effects of rheumatic diseases in several industries carried out by the Arthritis and Rheumatism Council's Industrial Survey Unit have indicated that, although the prevalence of rheumatic complaints varies between occupations, this variation does not seem to be related to the physical effort of the work involved (Anderson and Duthie, 1963; Partridge, Anderson...

As the cost of manufacturing microprocessors continues to rise, chip makers have begun accelerating the export of fabrication capabilities to overseas locations. This trend may one day result in an adversarial relationship between system builders and chip producers. In this scenario the foundries may hide additional circuitry to not only compromise operation or leak keys, but also to enable sof...

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...
