The present paper describes a rational analytical approach to a fire engineering design of load-bearing structures and partitions. The design method is permitted to be generally applied in Sweden, as one alternative, since about ten years. The method is directly based on the natural fire concept and strictly defined functional requirements and performance criteria . For facilitating the practical
A threshold analysis of terminated generalized LDPC convolutional codes (GLDPC CCs) is presented for the binary erasure channel. Different ensembles of protograph-based GLDPC CCs are considered, including braided block codes (BBCs). It is shown that the terminated PG-GLDPC CCs have better thresholds than their block code counterparts. Surprisingly, our numerical analysis suggests that for large te

Hur ställer sig samhället till en samverkan mellan universitetsforskare, som själva vill delta i den fortsatta kommersialiseringen, och industriella aktörer – dominanten eller utmanarna? Svaret har en tydlig EU-koppling och berör ett centralt satsningsområde för unionen, men hänsyn måste också tas till EU-rättens krav på att en effektiv konkurrens bevaras på viktiga innovationsmarknader. Vilka reg
In order to simplify computational methods based on dynamic programming, an approximative procedure based on upper and lower bounds of the optimal cost was recently introduced. The convergence properties of this procedure are analyzed in this paper. In particular, it is shown that the computational effort in finding an approximately optimal control law by relaxed value iteration is related to the
This thesis presents studies of solar wind-magnetosphere coupling using dynamic neural networks in combination with statistically correlative analysis. The primary contribution of the thesis is dynamic neural network models that can be implemented for near real-time predictions of geomagnetic storms from the solar wind alone. With acceptable accuracy, the prediction time has been extended up to 5
An introduction to the special issue of the European Journal of Migration and Law dealing with undocumented migrants.
The radiation balance of urbanised catchments differs from their rural counterparts, with snowpacks experiencing either enhanced or decreased irradiance depending on snowpack location and condition. As snowmelt is largely driven by radiation inputs, changes to localised irradiance (and melt rates) have implications for urban runoff generation. Storm- and wastewater drainage systems in cold regions
