Sammanfattning Denna studie utreder om ett långsiktigt samband mellan oljepriset och valda aktieindex kan påvisas. Tre typer av aktieindex har valts, generalindex, industriindex och råvaruindex, för Sverige respektive Norge. För att undersöka det långsiktiga sambandet mellan oljepriset och aktieindex används kointegrations- och regressionsanalys. Studien visar att det bara förekommer ett långsiktigt samband mellan oljepriset och ett fåtal av aktieindexen. Nyckelord: Olja, Kointegration, Tidsserier, Aktieindex Abstract This Study investigates if a long-term relationship between oil price and selected stock indices can be proved.

We have performed a study much similar to Ritter?s (1991) about long-term aftermarket performance of IPOs on the Swedish market during the years 1990 to 2002. The study resulted in evidence for that Swedish IPO do underperforms their benchmark-portfolios during a 36-months period. Though, the grade of underperformance depends of the chosen benchmark. The study is mainly focused on a particular benchmark, a portfolio of non-issuing firms matched by size and sector.

The aim with this thesis came out of a strong interest for Passage Retrieval. Our intention has not been to evaluate an IR-system. Instead our goal has been to analyze the result of indexing documents and their passages. We have been studying the weights of the different terms in the different indices, in comparison with other parameters like frequency, normalized frequency and the inversed document frequency. Further more we have been looking at how the weights are spread using for instance the standard deviation.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Recently, the selections of ethical funds are increased; at the same time investors with social and moral preferences have increased in the capital market. There are currently debates on whether ethical funds perform better or worse than funds without ethical criteria. This also involves a vivid discussion on whether investors know about the consequences of investing in ethical funds. Therefore, this study involves theories about the rationality and decision theory, in addition to what mainly control the investment decisions. The study also discusses portfolio theory since this is one of the underlying theories behind fund management and its development.The purpose of this study is to explain if ethical limitations in the selection of securities affect risk and return in the fund portfolio.

The Anybus CompactCom modules are today using the Anybus NP30 processor. These modules are used for communication between industrial machines and larger network protocols. The communication loads on these systems are increasing every day and the limiting factor for the system is the processor.HMS, the company that develops the Anybus CompactCom, has shown interest for a benchmark test between the old processor and a new processor, ARM Cortex-M3. This project includes that benchmark. To be able to get results that reflect reality a test environment was created to simulate Anybus CompactCom conditions.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.
