A method for modeling reflectionless conductive dispersive slabs is presented. The slabs are impedance matched to the surrounding half-spaces and are temporally dispersive with a spatially varying impedance. It is shown that the effects from the variation of the impedance can be matched by the temporal dispersive effects and the conductivity so that for a normally incident plane wave the slab does
For future robot control, there is a strong need for tools and methods supporting the development and deployment of control software. To this end, we propose a method for developing hard real-time software based on the standard Java language and multi-stage deployment and verification towards the embedded platform. This allows us to develop embedded Java software on the desktop using standard soft
The user services assistant (USA) is a novel reactive QoS agent that provides facilities for managing user to user QoS in Internet environments. By being reactive, it overcomes the problems associated with QoS management schemes that have been proposed to date, such as the mapping of the QoS parameters to end system parameters, and pre-determining the optimum way of degrading/upgrading the QoS. Ho
Eosinophils normally constitute only a few per cent of circulating leucocytes, though they are more numerous in tissues vulnerable to attack by environmental micro-organisms. Eosinophils can kill invasive parasites, but also possess immunoregulatory functions and may be involved, for example, in the connective tissue remodelling that occurs in conjunction with inflammation. Although their effects
This paper is a chapter draft from my thesis about personnel policy and industrial relations at the Swedish Tobacco Monopoly, 1915-1940. The paper focueses on the importance of short time work as a way of dealing with the severe recession in the early 1920s.
With the growth of mobile computing, users will have simultaneous access to multiple networks, each with different characteristics, services and costs. This paper introduces TOMTEN (TOtal Management Of Transmissions for the ENd-user), a framework for managing resources in this environment. TOMTEN is a reactive framework that is only active when either the application is started up or the user indi
