Methods are presented for the rapid design of DSP ASICs based on the use of hierarchical VHDL libraries. These are portable across many silicon foundries and allow complex DSP silicon systems to be developed in a fraction of the time normally required. Resulting designs are highly competitive with ones created using conventional methods. The approach is illustrated by its application to ADPCM c...

Nonconforming, and for their purpose unusable castings, not fulfilling the requirements of the standard and/or with customer agreed delivery conditions represent scrap [1, 2]. Scrap is manifested in foundries as waste in material, energy and labor. its efficient monitoring and supervision is possible only when the quality criteria have been unequivocally established, not only for the final prod...

Methods have been developed for the detection of exposure to carcinogens and other DNA damaging agents in experimental animals and man through the detection of carcinogens or their metabolic derivatives in body fluids, or through adducts bound covalently to DNA or hemoglobin. The successful use of urinary markers of genotoxic exposures has been reported with respect to nitrosoproline as an indi...

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...

PURPOSE The aim of this study was to determine cancer morbidity amongst Swedish iron foundry workers with special reference to quartz exposure. In addition to respirable dust and quartz, phenol, formaldehyde, furfuryl alcohols, polycyclic aromatic hydrocarbons (PAHs), carbon black, isocyanates and asbestos are used or generated by foundry production techniques and exposure to any of these subst...

The requirements for the quality and performance of brake pads railway rolling stock made various materials are analyzed. advantages cast iron produced at foundries shown. disadvantages composite based on rubber, asbestos, barite, carbon black other components noted. Ways to improve standards, specifications documentation these products proposed.
