The study of the history of the Gypsies in Sweden shows a marked continuity over time in regard both to content and starting point.It deals with two themes: the particular 'nature' of the Gypsies and their relation vis-á-vis the authorities. The point of departure is that the Gypsies are a foreign, 'secretive' and 'inaccesible' people, whose 'otherness' can not be accepted. Consequently they must

Social movements are series of sustained interactions and collective actions, contentious performances, displays and campaigns by ordinary people outside established political institutions. Yet, why do certain movements persist over a significant period of time while some do not? How do those that persist, sustain themselves and overcome constraints over time, especially those imposed by non-liber

This paper investigates expanding properties of ensembles of random bipartite graphs whose adjacency matrices are Gallager's low-density parity-check matrices. Two methods for calculating the expansion coefficient are demonstrated. It is shown that in the ensemble of the considered bipartite graphs, there exist graphs which have better expanding properties than the previously known expanders.

In this work we study the problem of constructing precoders for spatially multiplexed multiple-input multiple output (MIMO) channels with close to optimal minimum Euclidean distance. In order to exploit the full potential of such designs, an ML detector must be used. Our design takes the decoding complexity into account and constrain it to a reasonable level. For our simplest case, the ML detector

An improved method for simultaneous purification of complement factors C3, C5 and H from human plasma has been developed. Using an initial batch separation technique with QAE-Sephadex, followed by chromatography on SP-Sephadex and gel filtration in Sephadex G-200, 600 mg of highly pure C3 can be prepared from 1600 ml of plasma. Simultaneously about 70 mg of highly pure factor H and 30 mg of C5 are

This paper presents a theory to quantify the informational value of human acts. We argue that living is functioning against entropy. Acting is presented as a set of decisions and choices to create order that we use as the foundation to develop the concept of complexity of human acts. Frequency theory of probability is then applied to characterize human acts in terms of their degree of freedom and

Arbetsbyte för kompetensutveckling är en metod som ofta diskuteras men som verkar svår att genomföra i praktiken. Projektbidrag från Helsingborgs kommun gjorde det möjligt för Helsingborgs stadsbibliotek och Campus Helsingborgs bibliotek att pröva arbetsbyte för elva medarbetare under vintern 2008 – 2009. Detta paper bygger till stor del på de korta rapporter som projektdeltagarna skrev efter av
