Prefabrication of building components could be leveraged to improve reported low productivity trend in construction industry. Despite numerous known benefits of prefabrication, uptake of this technology has been discouragingly low. A nation-wide survey of consultants, contractors, employers and manufacturers was carried out in New Zealand and the received feedback was analysed. The subcomponents of the broad constraint categories and their relative levels of impact on the uptake of the technology were reported. Additionally measures for improving the uptake of the technology in construction...

With the latest trend in technology the size of the electronic devices has been encountered from the room size computer to nano-scale which has lead to quantum effect. At the length of the nano-scale electrons can only be observed as a wave rather than the particle. According to numerical point of view it is necessary to use a quantum model to analyse these quantum effects. Various researchers have proposed different numerical approaches to observe the quantum effects, for example, upwind difference scheme (UDS), Central difference scheme (CDS), Finite element method (FEM) and Finite volume...
