An algebraic/analytic method for reconstruction from image correspondences
A method for the reconstruction and motion problems is presented, under the assumption that a number of point correspondences in a pair of images are known. A geometric and algebraic theory is based on invariance properties of point configuration under affine and projective transformations. In particular, a characterization of those image pairs which correspond to the same point configuration in a

Absorbed Dose Determination and Characteristics of Degraded Electron Beams: Application to Intraoperative Radiation Therapy
Popular Abstract in Swedish Intraoperativ strålbehandling (IORT) innebär att en hög engångsstråldos ges direkt under operation till den kirurgiskt frilagda tumören och/eller kvarvarande tumörrester. Den vanligaste typen av strålning som används vid denna behandlingsform är elektronstrålning från konventionella medicinska linjäracceleratorer. Det krävs dock att ett speciellt applikatorsystem finns The aim of this work was to quantify limitations of and uncertainties in commonly used dosimetric techniques for relative absorbed dose determination in degraded electron beams, such as those encountered in intraoperative radiation therapy (IORT) and small-electron-field radiotherapy. Three different detector types were investigated with regard to measurements of output factors and relative absorb

Bioactivity of Medicinal Bolivian Andean plants. Effects on cell proliferation and related processes.
Popular Abstract in English Bolivia is the seventh richest country regarding biodiversity in the world. Also, in its territory more than 36 indigenous nations co-exist. Each of these has traditional medicines that are passed on from generation to generation orally. It has been estimated that the Bolivian flora has more than 20,000 plant species. Some of these are being explored for their pharmaceuColon cancer is common in both developed and developing countries, and is responsible for at least 600,000 deaths globally every year. It is therefore the second most common cause of cancer-related mortality. Extensive studies are being conducted worldwide to find more effective drugs that can be used in cancer treatment. In these studies, phytochemicals have proven to be good sources for drug dis
Det kristna Europa och gemenskapens gränser : Novalis Europatanke och samtiden
The article investigates the notion of 'Christian Europe' by tracing some of its ideological roots. In particular, it engages with the Romantic era of German philosophy. If the idea of Europe from its very earliest stage was closely linked to Christianity, this gesture also became an important element in the attempts of a number of Romantic poets and philosophers to seek the foundations for a new
Skriftens ansikten: Konsten att läsa mellan raderna
(2 uppl.) The biblical figures have stimulated the creative imagination of a wide variety of writers and composers during the past two millennia. This study surveys the reception history in poetry, novels, art and music of a number of biblical figures, e.g. Cain, Abel, Abraham, Isaac, Miriam, the poor widow (Mark 12:41-44), Peter, Judas and Barabbas. The book discusses the interpretations of the

Numerical Modelling and Analysis of Orthogonal Metal Cutting
Popular Abstract in Swedish De flesta komponenter som används i vårt samhälle har genomgått en bearbetningsprocess i något skede i sin tillverkningscykel. På grund av detta spelar de ekonomiska aspekterna av bearbetningsprocessen en viktig roll i tillverkningskostnaden. Det finns flera skäl till att utveckla ett rationellt förhållningssätt till skärande bearbetning, såsom att förbättra skärteknik,Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. There are several reasons for developing a rational approach to material removal, such as improving cutting techniques, producing products with enhanced precision, and increasin
Autonomy and Metacognition : A Healthcare Perspective
Part I of the dissertation examines the cognitive aspects of autonomy. The central question concerns what kind of cognitive capacity autonomy is. It will be argued that the concept of autonomy is best understood in terms of a metacognitive capacity of the individual. It is argued that metacognition has two components: procedural reflexivity and metarepresentation. Metarepresentation in turn can be
Sensitivity analysis of transient compressor operation behaviour in SOFC-GT hybrid systems
This paper presents a sensitivity analysis of unsteady-state SOFC-GT-HS operation based on two different characteristic maps of centrifugal compressor taken from open literature and scaled by the law of similitude to match the design point of the Hybrid System. The system layout under investigation is a pressurised type comprising a low and high temperature recuperator. Computations are based on a
Philosophical Modernization. Studies in Nordic History of Philosophy 1860-1910
Popular Abstract in Swedish Avhandlingen består av fem filosofihistoriska texter med en sociologisk och idéhistorisk orientering. Alla texterna rör sig inom samma tidsram, 1860-1910. De fokuserar vidare på filosofin i de nordiska länderna, och närmare bestämt universitetsfilosofin. Tre av texterna behandlar ämnets utveckling vid universiteten i Lund och Köpenhamn. Avhandlingens centrala tema är deThe dissertation comprises of five studies in the history of philosophy with primarily a sociological and history of ideas orientation. All the studies fall within the same timeframe, 1860-1910. Furthermore, they all focus on philosophy in the Nordic countries, and university philosophy in particular. Three of the texts take up the development of the discipline at the universities in Lund and Cope
A non-feedback multiphase clock generator
This paper introduces the design of a new multiphase clock generator with no feedback loop. A single-stage direct interpolation architecture is proposed. A 1/4 frequency divider and a short-circuit current suppression interpolator are developed to achieve the precise interpolation. The circuit has been fabricated in a standard 0.35 μm, 3.3 V CMOS process. The multiphase clock generator can operate
Evolution of Yeast Respiro-Fermentative Lifestyle and the Underlying Mechanisms Behind Aerobic Fermentation
Popular Abstract in Swedish Jäst kan antingen bryta ner socker direkt till koldioxid och vatten genom andning, eller indirekt via koldioxid och etanol, genom jäsning. Andning är en process som förbrukar syre, och sker därför endast under syrerika (aeroba) förhållanden. Jäsning kräver till skillnad från andning inte tillgång till syre, och kan därför ske under syrefattiga (anaeroba) förhållanden. Under aerobic conditions, most yeasts such as Kluyveromyces lactis, prefer the respiratory pathway and some, such as Saccharomyces cerevisiae prefer less energy efficient fermentative pathway for their energy metabolism. These two metabolic strategies are also known as Crabtree negative and Crabtree positive respectively, and the evolution of the latter has lately been explained by the “make-accum
