Asymptotically flat spaces are widely studied because it is one natural way of describing an isolated system in general relativity. In this thesis we study what happens to the Lanczos potential at Spacelike infinity in such spacetimes. By transformations of the Weyl-Lanczos equation, we derive expressions for the limiting equations on both the timelike unit hyperboloid, and the timelike unit cylinder. Finally the Newman-Penrose formalism is used to get a component version of the equations..

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

Emmanuel Lévinas is one of the great ethics in the 20th century. His contribution to the philosophical discourse defies our thinking and behavior in a revolutionary way. He dismisses every categorization, every tematization, every moral based on an analytical reflection and compels us with an ethics that demands us not only to think, but to act and be responsible. The 21st century?s emphasis of the individual, globalization, plurality and the questioning of authorities has created new challenges for the individual who sees herself as the nave of morality.

Dynamiken för en starkt accelerande robot har modellerats. Modellen linjäriseras så att roboten beskrivs som ett linjärt tidsvariabelt system. Denna representation beskriver roboten väl då robotens anblåsningsvinkel, vilket är vinkeln mellan robotkroppen och robotens hastighet, är liten. Eftersom det ej är möjligt att mäta alla robotens tillstånd har en observatör tagits fram i form av ett Kalmanfilter. Problematik vid framtagandet av observatören diskuteras i rapporten.

The first aim of this study is to discuss and try to understand the relationship between the holy andethics, and more specifically how it can be understood, which is the critical question that I haveformulated, in Giorgio Agamben?s and Emmanuel Levinas? philosophies. The second, moreconstructive aim is to discuss whether the holy can be understood as something good or problematicin relation to the society.Rooted in philosophy of religion and ethics, I have first tried to discuss how the holy has beenunderstood in the philosophy of phenomenology and in the texts of Rudolf Otto, Mircea Eliade andEspen Dahl. The holy has in the history been understood as something central in religions, and hasalso not been connected to the idea of ethics. Recently it has also been critized ? by Dahl ? for notbeing so pure as first thought of.In Levinas texts the holy has been understood as something differentiated through his distiction,in the Talmudic reading ?Desacralization and Disenchantment?, between the holy, which can beseen as something pure, and the sacred which can been seen as something impure and a form ofdegenerated holiness.

For the Swedish artist Björn Lövin, the personal was a problem. In his first exhibition in Moderna Museet, Lövin observed through the fictitious character Mr. P (for »Personality«) the ruptures in the Swedish welfare state. The exhibition Konsument i oändligheten och Herr P:s penningar (Consumer in Infinity and Mr. P?s Money) (1971) was composed of two environments, through which a veridical working class apartment and a high street with life-sized mannequins and furniture characteristic of its time, visualized the societal discrepancies in the welfare state as well as the art world of the early 1970s.

What is the relation of image and word, of sentences and pictures? What kind of message does this combination produce when juxtaposed on a single material plane? And how do we read its ?infinite? relation? These are the questions at the center of this inquiry. My main interest concerns the exact nature of the relation between photographic images and textual elements of poetic language when these are juxtaposed in what I call Phototext poetry.The thesis calls into question the conventional reading habits of the conjunction of photographs and texts, and seeks to understand the more complex connections intrinsic to the relation image/word and its material and perceptual play in poetic works. Does a text always ?anchor? the multiple meanings of an image, as Roland Barthes argues? What if the alterations of an image could ?anchor? certain fractions of a poetic, polysemantic textual construct? Is a photograph indifferent to the visual, material permutations of texts that certain contemporary poetic practices produce?I discuss phototextual works and collaborations of various kinds, from Molin fontän [?Molin?s fountain?] (1866) over classic surrealist poetry to language-oriented writing.
