The increasing use of unlicensed frequency bands for radio communications calls for investigations of the interference between coexisting radio networks. The wide variety of radio interfaces makes such investigations hard to perform. In this paper we present a general framework for the analysis of heterogeneous interfering radio networks, where the networks are modeled with individual properties f

Dramat under 1900-talets tre sista decennier kan sägas handla om de marginaliserade i samhället – barnen, de socialt utsatta, människor med olika etnisk bakgrund, de homosexuella och inte minst kvinnorna. Även språket står i centrum för intresset. Många skriver om hur människan påverkas av att ha ett språk och att inte ha ett språk. Mot de etablerade språkliga normerna ställs arbetarnas, de utslag

In this work, we examine a computationally efficient block-updating scheme for estimating the spectral content of signals with missing samples. The work is an extension of our recent single-sample data interpolation updating of the Iterative Adaptive Approach (IAA), being reformulated to incorporate blocks of samples. The proposed implementation offers a substantial complexity reduction as compare

In an intermedial reading of Astrid Lindgren’s oeuvre, Astrid Lindgren's World is not only analyzed as an ideal case of transmediality or remediation, but also as a modern form of a Total work of art. In doing so, the history of the genre ' total work of art' is discussed by broadening the common aesthetic point-of-view with angles from economy and advertising.

Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. In Paper A, the error correcting capability of tailbiting codes is described via the active distances for

“Diversify or die” is a recurring and rather dramatic call for organizations to recruit, retain and manage a demographically diverse workforce, advocated by the business case for diversity, also known as diversity management philosophy. Diversity management places diverse social identities at the heart of organizational success and has gained much attention from management consultants and managers

Popular Abstract in Swedish I och med upptäckten av antibiotika i första halvan av 1900-talet så kan flera tidigare dödliga infektionssjukdomar botas. Så är längre dock inte alltid fallet, en viss nivå av antibiotikaresistans har upptäckts hos flera stammar av kliniskt viktiga bakterier. Problemet med antibiotikaresistans har till viss del lösts med modifiering av existerande antibiotika, vilket dWith the discovery of antibiotics, several diseases that were previously lethal is today readily cured, or so we thought. Some degree of resistance to one or several antibiotics can be found among many strains of clinical important bacteria. The problem has been somewhat kept at bay for the last few decades by altering already existing antibiotics, and thereby prolonging their usage. It is clear t

A statistical analysis of low-density convolutional (LDC) codes is performed. This analysis is based on the consideration of a special statistical ensemble of Markov scramblers and the solution to a system of recurrent equations describing this ensemble. The results of the analysis are lower bounds for the free distance of the codes and upper bounds for the maximum likelihood decoding error probab

Dissociation is a complex concept that involves at least two different types of phenomena: the compartmentalization of psychological processes such as memory or identity that should ordinarily be integrated, and alterations of consciousness characterized by experiential detachment from the self and/or the environment. Although there are non-pathological manifestations of dissociation, this chapter
