In this chapter we provide an overview of the application of the results obtained in Sensoria (i.e., techniques, methods and languages developed in the technical work packages WP1-WP7) to case studies from the Automotive, eUniversity, Finance and Telecommunication domains (developed in work package WP8).

RF glow-discharge plasmas provide mild energetic ion bombardment of exposed surfaces. The characteristics of a 10 MHz RF glow-discharge Ar plasma are studied by particle-in-cell simulation. The model simulates a spherical plasma device using a one-dimensional plasma model. The code is used to determine the breakdown voltage, Vrf , for a given pd , where p is the gas pressure and d is the plasma...

We present a preliminary study of a new phenomena associated with the Euler-Poisson equations — the so called critical threshold phenomena, where the answer to questions of global smoothness vs. finite time breakdown depends on whether the initial configuration crosses an intrinsic, O(1) critical threshold. We investigate a class of Euler-Poisson equations, ranging from one-dimensional problem ...

This paper presents the Multiphysics Analysis of a High-Power Microwave Window for Ka-Band Klystron providing 16MW peak power. After optimization electromagnetic performances, we analyze effect RF heating and stress pressure on window. We also multipactor effect, that is common cause window failure. Using such approach, it possible to realize virtual prototype capable represent in complete way ...

Studies based on British Crime Survey (BCS) data suggest that the overall incidence of workplace assault is relatively low. However, these data have a number of limitations. They include only assaults carried out by clients or the public, provide limited information about the individuals involved and their workplaces, and tell us little about perceived causes of violence at work. The 2008 Workp...

Variable results of pain alleviation in response to acupuncture have been reported, complicating its interpretation. Sources of variability are probably multi-factorial, including the contribution of gender related effects. Gender related variation in perceived pain has been discussed frequently, but documented effects of acupuncture referring to gender are sparse. Furthermore, factors such as ...
