Abstract in Undetermined Pollenallergiker kan få ett bättre liv om de får information om tillståndet i luften. Det är till och med deras medborgerliga rättighet, enligt EU-direktiv, att få det. Därmed kan de förebygga symptom och planera sina aktiviteter. Avsikten med vår rapport är att bidra till underlaget för sådan en information, och att belysa hur de allergiska symptomen varierar med miljöfak
Electrical machines used in EV/HEV traction applications are usually driven at speeds where field weakening operation is required. In this region, electrically magnetized machines are more easily operated than permanent magnet machines. This paper discusses the performance of an electrically magnetized synchronous machine where the field coils are placed in magnetically conducting end-plates attac
On Christopher Polhem's inventions of war machines and other inventions for military purposes.
We performed high-resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6-Msolar main-sequence stars. We show that a resolution of about 100000 particles is sufficient for most studies of the structure and evolution of blue stragglers. We demonstrate conclusively that collision products
In this dissertation, The Public Library and the Museum of Modern Art in Stockholm – A Study of Architectural Criticism in the Swedish Press, the textual genre of architectural criticism is discussed from different perspectives. The principal aim is to illuminate, through a close reading of a sample of articles, how professional critics discursively and rhetorically communicate their idea of archi
Popular Abstract in Swedish Denna avhandling behandlar en speciell typ av felrättande koder som kallas tailbitingkoder. Syftet med en felrättande kod är att korrigera fel som kan uppkomma på grund av brus och störningar då digital information överförs från sändare till mottagare.Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. Conditions for when the tailbiting method fails are given, and methods for the proper initialization of the encoder are presented. Furthermore, the minimum distances of the tai
Abstract in Italian Nell’aprile 2011, al famoso logo della community di file sharing globale The Pirate Bay fu aggiunta l’immagine di una lente di ingrandimento e il nome del sito cambiò in The Research Bay. Gli utenti che cliccarono sul nuovo logo furono reindirizzati su un sondaggio online; durante le 72 ore di svolgimento dello studio, 75.000 file-sharer compilarono il questionario preparato da
To obtain high performance control of a dc-dc converter, a good model of the converter is needed. The load usually affects the dynamics and one way to take this into consideration is to regard the load as a part of the converter. The load is often the most variable part of this system. If the load current and the output voltage are measured there are good possibilities to obtain a good model of th
