Perceived slant produced by size disparities in random-dot displays was measured by tactile matching. For a 60 deg surface, slant produced by vertical-size disparity (the induced effect) was opposite to that produced by horizontal-size disparity. Overall-size disparity produced a little slant. With small displays, effects of horizontal and vertical disparities were reduced but not those of over...

There has been a growing demand to increase the throughput of computer systems. To meet this demand, we have been considering a massive parallel processing computer using a space division multiplex optical bus. In this scheme, optical signal data are transmitted from one board to another without E/O and O/E repeaters. Then, the parallel optical bus system requires laser amplifiers for vertical ...

introduction: marginal adaptation is the most critical item in long-term prognosis of single crowns. this study aimed to assess the marginal quality as well asthe discrepancies in marginal integrity of some pfm single crowns of posterior teeth by employing parallel radiography in shiraz dental school, shiraz, iran. methods: in this descriptive study, parallel radiographies were taken from 200 f...
