Since economic liberalization period, Chinese housing typologies have experienced a dramatical change. From the traditional Siheyuan building type to the current gated communities, which prototype has become the most widespread residential housing type in modern China Cities. At the same time, many negative feedbacks about the city life have been appearing, such as traffic congestion, the loss ...

The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...

Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...

one of the questions that has been ignored in letter of credit is a problem of assignment of proceeds in letter of credit that has been discussed generally below the transfer of lc subject, but has differed with it. so in this article, the author has tried to use the words assignment and transfer exactly in their place to clear the existent differences. at first, the writer’s hypothesis was tha...

A method for solving the descriptor discrete-time linear system is focused. For easily, it is converted to a standard discrete-time linear system by the definition of a derivative state feedback. Then partial eigenvalue assignment is used for obtaining state feedback and solving the standard system. In partial eigenvalue assignment, just a part of the open loop spectrum of the standard linear s...

there is not adequate information available about traditional instruction system in the field of visual arts in the pre-modern period. instruction of calligraphy can be considered as traditional instruction of art in a way that its guidelines and instructional texts are remained almost intact. instruction of calligraphy is implemented in aprofessor-student procedure and is accompanied with vari...
