Cycle Resolved Wall Temperature Measurements Using Laser-Induced Phosphorescence in an HCCI Engine

Cycle-resolved wall temperature measurements have been performed in a one-cylinder, port-injected optical Scania D12 truck engine run in HCCI mode. Point measurements at various locations were made using Laser-Induced Phosphorescence (LIP). Single point measurements with thermographic phosphors utilize the temperature dependency of the phosphorescence decay time. The phosphorescence peak at 538 nm

Shock structure for electromagnetic waves in bianisotropic, nonlinear materials

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

An embedded low power FIR filter

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,

Street art and museums

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

Dependable Automotive Systems based on Model Certified Components

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

Complementary Participatory Methods in SEAMLESS-IF

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

Virtual Networks, Support Stockings and Community: On-line publication- A new context of meaning for comparative education?

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

Safety culture in air traffic management: Air traffic control

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
