The enabling technologies for CAPE (Computer Aided of Production Engineering) emerged in the mid-’80s. Simulation, off-line programming, advanced graphics, motion emulation and powerful computers to support them all matured to the extend that CAPE technology could be brought into economically justifiable use. Introduction In the start of this millenium was changed old products by new, especiall...

this research was conducted in the west forest of guilan, northern iran. data from various harvesting methods for 20 years were collected. results showed that, productivity rate of round wood, pulp wood and fuel wood has had an upward trend, while rate of traditional products (lumber, sawn wood, charcoal, etc.) has had a downward trend. production cost has been investigated in this research. th...

Purpose – The purpose of this paper is to contribute to the body of knowledge associated with consumer socialisation. We investigate how children function as socialisation agents for their parents in influencing their purchase intentions of computer and high-tech products – essentially the idea of the young educating the old. Design/methodology/approach – A review of the extant literature relat...

the purpose of this project is the study of the natural gas {methane)steam reforming process through modeling and computer simulation. the operating parameters will be determined and then the? effect of changing these parameters on the conversion and purity of the final products will be studied. using computer simulation. the effect of the change in parameters will be studied along the lenght o...
