Carbon Fiber Reinforced Polymer (CFRP) has advantageous characteristics such as lightweight, high strength, corrosion and fatigue resistance, low creep, damping, etc. It is suitable to be used in bridge structures cables, which can effectively solve the problems of easy rusting, heavyweight, tensile performance steel cables. This paper firstly illustrates properties CFRP lamella compared with r...

Space-time block codes (STBCs) from non-square complex orthogonal designs are bandwidth efficient when compared with those from square real/complex orthogonal designs. Though there exists rate-1 ROD for any number of transmit antennas, rate-1 complex orthogonal designs (COD) does not exist for more than 2 transmit antennas. Liang (IEEE Trans. Inform. Theory, 2003) and Lu et al (IEEE Trans. Info...

Electron microscope studies of vertebrate retinas (1-4) have established that the outer and inner segments of each rod are connected through the so called "connecting cilium" (2). Examination of a large number of sections of vertebrate retinas occasionally reveals however, abnormal rods whose outer and inner segments are in direct continuity. Morphogenetic studies of such abnormal rods can serv...

abstract   background: pseudoarthrosis of the tibia poses one of the most challenging treatment problems in all of orthopedics. the goal of the study was to assess the clinical outcome of intramedullary rod fixation in its treatment.   methods: the results of the management for nine patients with pseudoarthrosis of the tibia with im rod fixation were reviewed retrospectively between 1986 - 2006...
