Railway yard is the basic composition unit of railways, therefore, the efficiency and quality of railway yard design have a crucial effect on the construction and operation of railways. Plane design is the basis and core of railway yard design, consequently, it is significant to research plane design of railway yard. In this study, through analysis and summary of the research status as well as ...

In today’s era of plasma and laser cutting, machines using oxy-acetylene flame are also meritorious due to their simplicity and cost effectiveness. The objective to devise a Computer controlled Oxy-Fuel profile cutting machine arose from the increasing demand for metal cutting with respect to edge quality, circularity and lesser formation of redeposit material. The System has an 8 bit micro con...

This paper describes the development of computer-aided design of a very precise progressive die for lead frame of semiconductor chip. The approach to the system is based on knowledge-based rules. Knowledge for the system is formulated from plasticity theories, experimental results, and the empirical knowledge of field experts. This system has been written in AutoLISP using AutoCAD on a personal...


 Las metodologías no destructivas empleadas para determinar área foliar mediante capturas fotográficas y posterior procesamiento han tenido una importante acogida en diversas disciplinas. Sin embargo, son escasos los estudios que validan términos de precisión exactitud el efecto la coplanaridad o no-coplanaridad entre planos cámara hoja. En este estudio se evaluó valores obtenidos planta ...
