Shock waves are discontinous solutions to quasi-linear partial differential equations, and can be studied through a singular perturbation known as the vanishing viscosity technique. The vanishing viscosity method is a means of smoothing the shock, and we study the case of electromagnetic waves in bianisotropic materials. We derive the conditions arising from this smoothing procedure for a traveling

A new sampler with embedded FIR filter was designed with the charge sampling technique. The filter functions by summing the weighted current on a passive capacitor and the weighting factors are decided by the FIR coefficients. The performance of the filter can well compete with conventional analog filter but with smaller area and less power consumption. A testing chip was designed with 2 V supply,

Presentation about the difficulties involved when attempting to represent graffiti and street art in an institutional context.

Advances in Intelligent Transport Systems (ITS), intelligent vehicles and cooperative systems are enabling traffic and transport solutions that are both safer and more environmentally acceptable. While it is well known that high dependability is a desirable feature it has a price, and the level of dependability needed varies from application to application. Typical examples are cooperative safety

I denna sammanfattning av ett anförande vid en FRN-konferens i Örebro om familj, samhälle och hälsa, presenteras tanken på det starka hushållet som en grundläggande förutsättning för samhällshälsan under tidigmodern tid.

The aim of this report is to describe situations where interactive work methods are needed and to suggest suitable participatory methods to enable the use and user involvement in SEAMLESS-IF. Interaction with users and stakeholders are needed for two different purposes. First during different stages of the development of the SEAMLESS-IF itself and second as interaction with users and stakeholders

This article addrsses the advant of this online only publication, the very context in which it is being made available. Central to this article is Delanty's work on communicative communities. It is argued that it is particularly appropriate to view comparative and international education in this manner. Online publication offers comparative and international education a new context of meaning. See

In a joint research project – Human Factors in Air Navigation Services, HUFA – between the Swedish Civil Aviation Administration and Lund University the focus is on human and organizational factors and safety in air traffic control. The Swedish Air Navigation Services (ANS) are undergoing major organizational changes in order to adapt to changing demands on efficiency and technical development in

Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. I especially focused on salinity problems, as they occur in southern Tunisia, where I performed several field
