We present an abstract machine that encodes both type safety and control safety in an efficient manner and that is suitable as a mobile-code format. At the code consumer, a single linear-complexity algorithm performs not only verification, but simultaneously also transforms the stack-based wire format into a register-based internal format. The latter is beneficial for interpretation and native ...

usd7 is one of the steel products of isfahan steel company. it is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. finally, it is wire drawn up to 3 mm and used as welding electrodes. this steel contains 0.05 to 0.09 wt. % carbon. the acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. therefore, it is categorized as rimmed steel. during fo...

High carbon high chromium alloy tool steels (D-3) with excellent abrasion resistance (HRC: 58-65) are increasingly used in manufacturing high performance cutting tools (dies and punches), blanking and punching tools, extrusion tools, etc. Being a hard material, it is difficult to machine using conventional machining methods. Wire Electric Discharge Machine(WEDM) seems to be a viable option to m...

In order to digitally control the bonding force of a wire bonder precisely, this paper uses a DC solenoid as a force source, and by controlling the solenoid’s current, which causes the electromagnetic force, we can control the bonding force that capillary applies. The bonding force control system in this paper is composed of PC (Personal Computer) and hypogyny MCU (Micro Controller Unit), which...

Maze routing is widely used in both printed circuit board (PCB) and VLSI design. However, for the ever increasing design requirements, this can no longer he done economically without the help of special purpose hardware accelerators. A new hardware accelerator comprised of several fast processors interconnected in the form of a hexagonal mesh with wraparound connections is proposed. The novelty...

• Direct comparison of property profiles depending on the manufacturing process and alloy. One-step direct extrusion wires up to a diameter 0.2 mm. DRX is dominant mechanism for texture development in SRX wire drawing, resulting different profiles. Improvement properties significantly by especially after first two passes. This paper deals with impact mechanical magnesium alloys, AZ31 ZX10. For ...

During the reconstruction of the ISOLDE on-line mass separator facility at CERN one of the goals was the development and implementation of an efficient and user friendly beam observation system. The pick-up devices used on the two mass separators and the beam lines are mainly Faraday cups, wire scanners and wire grids. Most of these items were specifically designed at ISOLDE, in particular, a l...

This paper describes a novel method to measure straightness error of an axis of motion with a system utilising taut wire, optical sensor and reference error cancellation technique. In contrast to commonly used taut wire, straightedge or laser-based methods it combines simplicity of setup and low cost with high levels of automation, accuracy and repeatability. An error cancellation technique bas...
