On robustness of turbo coded OFDM systems over frequency selective channels
The robustness of fixed Turbo coded communication systems over frequency selective channels are investigated. The simulated amplitude functions are based on an idealised two level function and a decaying function. The results indicate that the system can cope with severe disturbances without to much loss.

Phonetic preconditions for historical sound change - evidence from the dialects
Universal perception and production constraints may constitute phonetic preconditions for historical sound change. It is pointed out that the traditional literature on the Swedish dialects provides a rich source of information in evaluating the diachronic role played by these constraints.
The need for a verification and validation protocol for evacuation models
To date, there is no standard Verification and Validation (V&V) protocol for the evaluation of evacuation model predictions. This paper is intended to open a discussion on the main issues associated with the definition of a standard procedure for the V&V of building fire evacuation models. Examples of such issues are discussed, namely 1) the definition of tests able to investigate the capa

Gas Flow and Heat Transfer Modeling of an Anode-Supported Solid Oxide Fuel Cell Duct
The composite duct considered consists of a thick porous anode layer, the gas flow duct and a solid inter-connector. Unique fuel cell boundary conditions, such as combined thermal boundary conditions on solid walls, mass injection by electrochemical reaction and gas permeation across the interface, were applied in the analysis. The characteristics of gas flow and heat transfer were investigated an

An XML Representation of DAE Systems Obtained from Modelica Models
This contribution presents an XML format for representation of flat Modelica models. The purpose is to offer a standardized model exchange format which is based on the DAE formalism and wich is neutral with respect to model usage. Many usages of models goes beyond what can be obtained from an execution interface offering evaluation of the model equations. Several such usages arises in the area of
Personality of university teachers according to the Defense Mechanism Technique modified (DMTm) as related to their assessment of their university as an organizational setting
The present study considers possible relations between personality and orgnizational-assessment variables. Subjects in a stratified sample of 114 university teachers, 36 women and 78 men, were examined using the Defense Mechanism Technique modified (DMTm), a percept-genetic technique. They also made assessment of their university as an organization. Two data sets were formed initially, the one con
Simulation of Dynamic Discontinuous Recrystallization During Hot Deformation of Pure Copper
A probabilistic cellular automaton technique is employed in the simulation of dynamic discontinuous recrystallization (DDRX) in pure copper under hot deformation conditions. Important features of the present model are calibration of grain growth kinetics against the analytical solution and also the description of a misorientation-dependent grain boundary energy, valid in the entire range of misori
Essay SI - Taking SI to a Higher Level
Workshop held at the 6th International SI Conference, New Orleans, USA, May 2010, discussing the outcomes of a pilot program in Lund appying SI to the essay level of teaching. Both the benefits and the problems were discussed
