where d = thickness of the film, ,o = resistivity of the film, = resistivity of the bulk material having the same structure and approximately the same number of defects as the films, l0 = mean free path of the charge carriers. The values of l0 calculated by the two methods were found to agree satisfactorily. Figs. 7 and 8 show the variation of the Hall mobility (/̂ H) with film thickness and sub...

THE SYNDROME of glossopharyngeal neuralgia associated with disturbances of cardiac and cerebral function is a rare disorder, having been reported to our knowledge in only 16 patients.1 '4 It is characterized by paroxysms of neuralgic pain in the throat and neck and accompanied by bradyeardia or asystole, hypotension, syncope, and sometimes seizures. The following report describes detailed cardi...

There are several reasons why conventional speech recognition systems modeled on adult data fail to perform satisfactorily on children's speech input. For instance, children's vocal characteristics differ signi cantly from those of adults. In addition, their choices of vocabulary and sentence construction modalities usually do not conform to adult patterns. We describe comparative studies demon...

For almost two decades the question of whether tabu search (TS) or simulated annealing (SA) performs better for the quadratic assignment problem has been unresolved. To answer this question satisfactorily, we compare performance at various values of targeted solution quality, running each heuristic at its optimal number of iterations for each target. We find that for a number of varied problem ...

SLAC-PUB-4345 Js 1987 Towards a Personal Mainframe* iDavid Aston Stanford Linear Accelerator Center Stanford University, Stanford, California, 94305 Aspects of computing in a mainframe environment are discussed with reference to the SLAC installation. Personal computers have revolutionised users’ expectations, yet the centralised mainframe continues to offer indispensible advantages. Many of th...

Temafloxacin disk susceptibility test criteria were evaluated by testing 697 bacterial isolates. Either 5- or 10-micrograms disks could be used satisfactorily. A 5-micrograms temafloxacin disk with zone size breakpoints of less than or equal to 12 mm for resistance (MIC, greater than 4.0 micrograms/ml) and greater than 16 mm for susceptibility (MIC, less than or equal to 2.0 micrograms/ml) is r...

Subarachnoid anaesthesia was induced with 0.5% bupivacaine 2-3.5 ml in 33 women scheduled for elective Caesarean section. Three patients failed to develop adequate analgesia with bupivacaine but were managed satisfactorily with heavy cinchocaine. All the other patients developed adequate analgesia eventually. Since the spread of analgesia was uniquely dependent on posture a new hypothesis is pr...

An automated method to register Medical Images is presented in this work. This new technique employs an iterative warping scheme and is performed, either over fully pixel information or using geometrical features such as ridges. The warp at each iteration is given by a number of local Finite Element transformations which provide a non-linear global warp. Results show that this technique can be ...

This case series presents two females, 53 and 33 years old, with thyroidectomy wounds that failed to heal, 16 and 18 weeks, respectively, following the operation. The wounds were explored with removal of gauze and catgut suture. The patients made remarkable improvement and the wounds healed satisfactorily within seven days. Surgical materials forgotten intraoperatively, wrong use of and / or in...

In this paper, a novel approach of using genetic algorithm towards realization of Chua’s circuit is presented. The paper demonstrates the use of genetic algorithm to evolve Chua’s circuit from a set of given passive and active components. More than a dozen of the evolved designs are demonstrated to work satisfactorily in simulation. The evolved designs are found to be human competitive and are ...
