The main goal of SASPENCE is to develop and evaluate an innovative system able to perform the Safe Speed and Safe Distance concept, that means to help the driver in avoiding accident situations related to excessive speed or too small headway. So, the system should co-operate seamlessly with the driver, suggesting the proper velocity for the given condition (road structure, traffic situation, etc.)

Since some years ago greenhouse gases and especially carbon dioxide have become one of the most widely debated issues. To reduce the emission of carbon dioxide and nuclear waste, renewable energy sources as for example wind power plants have become very successful. These generation units are normally small compared to common thermal power plants and they are often placed distributed and connected

This paper presents a study of scholarly blogs. The aim is to gain an in-depth understanding of what characterizes blogging as part of the scholarly communication within epistemic cultures. A study was conducted of 16 scholarly blogs, from two different scientific areas. Eight blogs from high energy physics (HEP) and eight from digital history were closely followed. The analysis was made by employ

The thermal stresses in a concrete bridge are affected by the surrounding climate. Varying temperature will produce movements which, if restrained, may induce stresses in the structure. To predict the thermal stresses due to climatic effects in concrete box cross-sections, FE simulations have been performed with extensive climatic input data to simulate the temperature and resulting stress fields

Estimation and Model Validation of Diffusion Processes Abstract The main motivation for this thesis is the need for estimation and model validation of diffusion processes, i.e. stochastic processes satisfying a stochastic differential equation driven by Brownian motion. This class of stochastic processes is a natural extension of ordinary differential equations to dynamic, stochastic systems

This chapter presents methods for analysing interdependencies in critical infrastructures. In general, there are three groups of methods for analysing interdependencies; (1) conceptual, (2) model and simulation and (3) empirical and knowledge-based approaches. Examples of methods belonging to these groups are presented. The latter part of the chapter discusses challenges related to modelling, focu

The decay process in rooms with non-diffuse sound fields was the subject of this investigation. A rectangular room with high absorption at the ceiling and low absorption at the walls and floor constituted the basic configuration for the study. Several alterations of the room were carried out, including changes of room dimensions and the type of ceiling absorber, also additional treatment with abso

Krönikeartikeln behandlar ur olika synvinklar de stora och växande skillnaderna mellan medlemsavgifterna till olika a-kassor. Akademikerkassan AEA tillhör kassorna med lägst avgift (oktober 2009) medan LO-kassorna i allmänhet har högst avgifter.
