Validation of a 1D transient heat and moisture calculation tool under real conditions

Stricter Swedish building regulations require a moisture-safety design process to be carried out before houses are built. In order to predict moisture-critical conditions, a properly verified, user-friendly and reliable calculation tool that could be used in this design phase, is required.This paper initially presents a blind method that could be used in order to verify heat and moisture calculati

A Software Tool for Robust PID Design

This paper presents a fast, interactive and easily modifiable software tool for robust PID design. The Matlab based program is supposed to give people with moderate knowledge on PID control a possibility to learn more and also be a future part of an autotuner. The PID design is made by minimizing the integrated absolute error value during a load disturbance on the process input. The optimization i

Privacy preserving neighborhood awareness in vehicular ad hoc networks

Location information is exchanged among members of Vehicular Ad Hoc Networks (VANET) to serve many road and safety applications. Vehicles will announce their identity, position, and mobility information to their neighboring nodes. The importance of such information makes privacy a major concern. Successful implementation of VANET requires protecting the vehicle's identity at all times and preventi

Precision Issues in the implementation of BCJR decoders

The BCJR algorithm is a symbol-bysymbol soft-output MAP decoder for trellis codes. This paper studies the effect of wordlength variations on the BCJR performance and looks at two strategies for reducing the wordlength.

Sigrid Combüchen's Parsifal – time and memory in a dissoluting Europe. A Narrative analysis in Comparison with Aethiopica by the ancient novelist Heliodorus (300 AD).

A comparison between the narrative technique of the ancient Greek novel, 'The Aethiopica' by Heliodorus, and Sigrid Combüchen´s modern tale 'Parsifal'. Sigrid Combüchen is a Swedish writer, born in Germany 1943, a european 'war child'. Her tale Parsifal (1998) gives perspective of the perils in European history. She uses a historical, mythical and contemporary narrative in a genuinely inventive

Students' communicative behaviour in a foreign language classroom

The purpose of this paper is to give a description of the communicativity in a foreign language classroom and also of students’ communicative behaviour. Since the beginning of the 80s communication has been widely discussed as one of the main features in instructed language learning. The focus on form, that traditionally has been dominant in the language classroom, was combined or even replaced by
