In this paper we examine the ambiguities between extrinsic and intrinsic parameters in the uncalibrated structure and motion problem. The Jacobian J of the reprojection error is considered, treating each camera separately. Ambiguities correspond to linear dependencies in the column space of J and we thus detect and quantify these by using the condition number of selected combinations of columns of
This paper reconsiders how central banks get involved in the process of determining nominal variables such as market interest rates and inflation rates. It is argued that the traditional story deriving central bank power from its monopoly of issuing base money is flawed. That story - in its various guises - is based on the quantity equation. This equation, however, is only applicable in the hypoth

This report has been compiled within the framework of the programme on Regional Air Pollution in Developing Countries (RAPIDC), Phase III conducted during the period 2005-2008. RAPIDC is funded by the Department of Infrastructure and Economic Cooperation (INEC) of the Swedish International Development Cooperation Agency (SIDA). It is coordinated by the Stockholm Environment Institute (SEI) and car
Language use is fundamentally multimodal. Speakers use their hands to point to locations, to represent content and to comment on ongoing talk; they position their bodies to show their orientation and stance in interaction; they use facial displays to comment on what is being said; and they engage in mutual gaze to establish intersubjectivity. This volume brings together studies by leading scholars
De nordiska länderna har i stort sett likalydande avtalslagar. Den svenska avtalslagen har i år varit i kraft i 100 år och avtalslagarna i de övriga nordiska länderna är nästan lika gamla.I denna bok bidrar ett antal nordiska rättsvetenskapliga forskare med analyser av avtalslagarnas bakgrund, deras nuvarande betydelse i den moderna nordiska avtalsrätten liksom frågan om hur väl de kan förväntas f
Load demand in residential houses is a significant contributor to peak load problems experienced by utilities. The knowledge about demand variation in households is fairly limited as well as the use of various tools to analyze the demand. Many utilities have recently installed interval (hourly) metering at their residential customers. The availability of hourly data is a significant progress, howe
Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. This thesis describes methods developed to study polymer morphologies by electron microscopy and also

Labor market policies have been re-configured during the ´activation turn' in labor market policy-making in the 1990s. This included restricting behavioral requirements for job seekers and benefit claimants, but also improving services (e.g. better placement services). In a nutshell, the `rights and responsibilities' of jobseekers and labor market participants were re-balanced. To date, there is o
Regulation of the electricity network business is continuously under development in many countries. This is a reaction of an increasingly electricity dependent society, which demands electricity supplies at acceptable quality levels and at reasonable tariffs. Thus, electric network companies are facing new requirements that change the conditions for exercising network activities. Generally, incent
