Abstract More than a century after the discovery of superconductors (SCs), numerous studies have been accomplished to take advantage SCs in physics, power engineering, quantum computing, electronics, communications, aviation, healthcare, and defence-related applications. However, there are still challenges that hinder full-scale commercialization SCs, such as high cost superconducting wires/tap...

Abstract The typical power transformer diagnosis approach is imprecise and unstable. A support vector machine classification algorithm proposed, by designing an program that can improve the accuracy speed of energy diagnosis, vibration signals surface twisting in different states are extracted wavelet packet spectrum signal processing method, it verified curve similarity between simulation mode...

Worldwide, millions of kilometres sewers are constructed from concrete pipes. Unfortunately, susceptible to corrosion biogenic hydrogen sulphide, and, though they may pass visual inspection, their ability hold together under load be degraded. This paper presents the design a teleoperated robot with protractible probe, that allows an operator apply localised selected points within sewer pipe. We...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

in view of the increase in saccharomyces cerevisiae mannan content, the culture condition for s.cerevisiae were optimized in this study. the influence of culture condition such as original ph, inoculum size, and temperature on mannan production were evaluated using response surface methodology. the mathematical model was established by the quadratic rotary combination design. with the order of ...
