The authors report the fabrication and I-V characteristics of ZnO nanorod metal-semiconductor-metal photodetectors on flexible polyimide substrate. From field-emission scanning electron microscopy and X-ray diffraction spectrum, ZnO nanorods had a (0002) crystal orientation and a wurtzite hexagonal structure. During the I-V and response measurement, the flexible substrates were measured with (i...

The numerical dimensioning of injection heads and tools for the extrusion of rubber profiles requires both, the experimental investigation and numerical consideration of the viscoelastic material behavior. Usage of finite element software allows drastic reduction of a time-consuming empiric adaptation process for the design of extrusion tools. In this context, viscoelasticity covers three diffe...

introduction: few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. the purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. methods: using sixty fully replicated master casts obtained by duplicating a metal die represent...

For each cooperative n-person game v and each h 9 { 1, 2 . . . . . n !, let v h be the average worth of coalitions of size h and v~ the average worth of coalitions of size h which do not contain player is N. The paper introduces the notion of a proportional average worth game (or PAWgame), i.e., the zero-normalized game v for which there exist numbers ch 9 ~ such that D,-v~=ch (vn_l-vi_]) for a...
