Recent research has indicated that invariants can be useful in computer vision for identification and pose determination of objects. The idea is to find functions that are invariant under a set of transformations acting on a configuration space. This paper describes some new viewpoints on the construction and use of such invariants. The key idea is that any kind of features like derivatives, disti

A composition is a vector of positive components summing to a constant. The sample space of a composition is the simplex and the sample space of two compositions, a bicomposition, is a Cartesian product of two simplices. We present a way of generating random variates from a bicompositional Dirichlet distribution defined on the Cartesian product of two simplices using the rejection method. We deriv

Popular Abstract in Swedish Denna avhandling fokuserar förändringar inom den arbetsmarknadspolitik som erbjuds arbetslösa socialbidragstagare mellan 1989 och 2002 i Sverige. Denna förändring beskrivs som en process där kommunerna tar allt mer ansvar för arbetsmarknadspolitiken. Denna grupp arbetslösa kategoriseras som en speciellt problematisk grupp och hänvisas till kommunerna. Detta sker utan tyThis dissertation focuses on changes in labour market policies that were provided for unemployed recipients of social assistance between 1989 and 2002 in Sweden. This change is described as a process where the municipalities gradually take greater responsibility for the labour market policies. This group of unemployed is categorized as a particularly problematic group and has been referred to the

Den här rapporten presenterar ett aktionsforskningsprojekt i form av en poesicirkel med sjuksköterskor som arbetar med svårt sjuka och döende människor. Med hjälp av dikten så bearbetar de sina existentiella tankar och upplevelser. Poesin hjälper på så sätt sjuksköterskorna att ge känslorna ett språk. I den aktionsinriktade processen ger sjuksköterskorna uttryck för att poesin hjälper dem att få i

Abstract in UndeterminedVehicles, symbolic goods of modern society, cause serious environmental impact in their endof-life phase owing to present end-of-life treatment practice and abandonment in nature. Theenormous volume of vehicle waste, and accompanying environmental impacts, encourageseeking an environmentally effective policy solution to control the problem of end-of-lifevehicles. This thesi

6 x Saudek. Aspects of an Artist’s Work is about the Czech photographer Jan Saudek (b. 1935) and his pictures. The thesis deals with Saudek’s photography from the 1960s up to and including the 1990s and comprises six relatively self-contained chapters. Each chap-ter takes up a specific range of problems: they deal with issues concerning connections between photography and theatre (chapter 1); issu

Where, if, and how, should researchers draw the limit between gesture proper and semiotically less complex forms of bodily conduct that do not quite qualify as gesture? This is the question of a lower limit of gesture (Andrén 2010). In accord with a comparative semiotic approach (Kendon 2008) I suggest that the question is best understood, not as a binary distinction between gesture and non-gestur
