BACKGROUND Thoracoscopic surgery has become very popular in recent years. Conventional thoracoscopic surgery requires three or more port wounds for manipulations of endoscopic instruments. For complicated cancer surgery, more port wounds and a larger thoracotomy wound may be required due to technical reasons. We want to investigate the effectiveness of single-port thoracoscopic approach in elec...
ÐThis paper begins with an overview of realistic fault models for dual-port memories, divided into single-port faults and faults unique for dual-port memories. The latter faults cannot be detected with the conventional single-port memory tests; they require special tests. A precise notation for all faults, such that ambiguities and misunderstandings will be prevented, has been emphasized. Next,...
A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...
