Nowadays, with the increasing pressure of the competitive business environment and demand for diverse products, manufacturers are force to seek for solutions that reduce production costs and rise product quality. Cellular manufacturing system (CMS), as a means to this end, has been a point of attraction to both researchers and practitioners. Limitations of cell formation problem (CFP), as one o...

Production of a new mechanism involves design, manufacturing and testing phases. In order to achieve shorter turn-around times, researchers have studied methods of shortening these phases. Today, structural tests and simulations conducted in virtual environments prior to manufacturing are a part of most of the standard production processes. However, in robot production not only the structural a...

The competitive situation in automotive industry and increasing market demands necessarily lead to higher complexity in product development, production planning and production ramp-up processes. One key challenge for mobilising important time and cost resources in production engineering projects is a virtual validation of the ramp-up. Especially in cross-functional cases where many planning dep...

As a result of the growing demand for highly customized and individual products, companies need to enable flexible and intelligent manufacturing. Cyber-physical production systems (CPPS) will act autonomously in the future in an interlinked production and enable such flexibility. However, German mid-sized plant manufacturers rarely use virtual technologies for design and validation in order to ...

the subject under investigation has been electronic learning (e-learning) or electronic education (e-education), specifically concentrating on virtual university. virtual university has been the subject of much debate in recent years. in short, the concept of virtual university denotes a learning/educational system/environment based on internet where higher education is promoted using tools and...

background : along with emersion of the internet, virtual education increasingly has been growing. many studies discussed this method and its impact on learning. present study investigated students’ attitude towards virtual education as well as its effect on learning. methods : this was a pretest-posttest quasi-experimental study. the nursing students, who had selected fluids and electrolyte di...

PURPOSE "Virtual patients" are computer-based simulations designed to complement clinical training. These applications possess numerous educational benefits but are costly to develop. Few medical schools can afford to create them. The purpose of this inventory was to gather information regarding in-house virtual patient development at U.S. and Canadian medical schools to promote the sharing of ...

To construct more realistic virtual marine world, it required the marine environment and the production of objects through consideration of spatial characteristics and a system that can support the various forms of interactions. This paper proposes an architecture that includes realistic data, smart object modeling, 3D visualization and interaction that are the levels of the construction of the...

there are  many  definitions  about  economy . according  to  one of  the  famous  accepted  definitions , economic  laws  have  classified  to two  groups. both  of  them  are  influenced  by  social  structure  and  it’s  changes  so  they  are  different  in  various  societies . movement  from  one  society   to  another  happens  due  to “intellectualize” , principal  maximum  production  ...
