Electrical de-icing consumes more power than is generally available from the generators. Therefore, electrical de-icing only becomes feasible, if the power is merely used during limited time intervals to melt the ice and separate it from the wing. The airflow then simply carries the ice away which avoids the need for further power to melt or even evaporate the ice totally. The ice slabs forming...

Web service compositions (WSC), as part of a service-oriented architecture (SOA), have to be managed to ensure compliance with guaranteed service levels. In this context, a high degree of automation is desired, which can be achieved by applying autonomic computing concepts. This paper particularly focuses the autonomic management of semi-dynamic compositions. Here, for each included service sev...

Traffic Control and management poses a major problem in urban cities, especially in rapidly growing & motorizing cities. In urban cities at road intersection traffic lights (Red, Green and Yellow) is used for controlling the congestion. For this there a set up of complete system called traffic control system at the road intersection. But there is chance of failure of individual unit of traffic ...

Multipactor in beam-pipe transitions of superconducting RF cavities can be explained using RF potential well theory [1]. In this paper we present simulation results supporting this explanation for both RF cavities and transmission lines. INTRODUCTION Curved-shaped transition regions between a cavity and a beam pipe were thought to be multipactor-free. Thus recent experimental observations of mu...

This study investigated which variables distinguish high school-aged adolescents who identify themselves as members of a high-risk group and, among them, those who report regular (weekly) vs. light levels of cigarette smoking. Youth who identified with a highrisk group were most likely to report problem-prone characterI dentifying predictors of adolescent cigarette smoking has remained an impor...

It is usually believed that the blocking probability of a switching network will increase with the increase of the failure rate of building components (e.g., links, switching elements, etc.) in the switch. In this report, we propose a mathematical model for evaluating the maximum blocking probability of optical banyan networks on vertical stacking when the link failures are considered. Based on...

The introduction of reentrant shape for superconducting cavities has made it possible to achieve record-high gradients. In this paper it is shown that lowest losses in the cavities are also achievable employing the reentrant shape. Influence of the cavity wall slope angle on the extreme gradient and losses is analyzed. INTRODUCTION The reentrant shape was obtained as the best shape for maximal ...

Rates of oxidation of aldoses with bromine have bee n reappraised and inte rpreted in th e light of present concepts of conformation and reaction mechanism. It is suggested that differences in t he rates of ox idation of the a and /3 anomers are largely determin ed by differences in the free energy req uired by the reactants for passing from the ground state to the com plex in the transition st...
