Profitability of Momentum Strategies on the Nordic stock market
Purpose: The main purpose of the thesis is to examine the profitability of Momentum Strategies on the Nordic stock markets. This will provide insight and contribute to the debate on efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momentum Strategy. We will look closely at the relationship between the profitability and factors such as risk (CAPM-beta), market capitalization, trading volume and seasonality.
Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader
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.
Krav och önskemål på skogsbruksplanen : förbättringspotential med laserskanning
In 2009 The National Land Survey of Sweden, Lantmäteriet, commenced a project intended to provide a new digital elevation model (DEM) of Sweden. The method chosen for the project was airborne laser scanning (ALS). In addition to information about the land surface the project will also provide information about the forest, this as a by-product. This data can be used to estimate forest variables such as height and volume. The estimates are often more reliable than what is standard today.
This study is based on interviews with employees and members of the forest owner association Södra in southern Sweden.
Janus två ansikten : En studie om kökslärarens dubbla roller
This is a field study based on participant observations and interviews, describing the cooking teacher's complex everyday life. The school's restaurant is a unique arena, freely hovering between two worlds: The school world and the restaurant reality. Here, the students are confronted with real situations and problems, similar to the ones occurring in a restaurant, still having the school's safety net beneath them. It is for real, but still not, a bit like a flight simulator.It is on that arena the cooking teacher works, combining the two roles of the teacher and the chef. Two roles built on their own traditions and values.
Död ved i gallrad skog och nyckelbiotoper : en jämförelse av habitatkvaliteter för vedlevande lavar och mossor
A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. In old-growth forests most of the dead wood consists of logs and snags, whilst in managed forests a huge proportion of dead wood is made up of logging residues like stumps and FWD, fine woody debris (< 10 cm diameter). All these different types of dead wood may serve as substrates for epixylic bryophytes and lichens. However, few studies have been conducted on the relative importance of these different fractions of dead wood for the occurrence of bryophytes and lichens, especially when considering dead wood on thinned forest land.
KRÄDD Konsten att balansera Ekonomiskt och Kulturellt Kapital
This thesis aims to describe how a fashion designer should balance art and commerce in order to succeed in the fashion industry. We aim to define the Swedish term KRÄDD, and sort out how a designer or CEO in the fashion business should relate to the term, as well as the balance between cultural and economic capital. We present theories of the origins and fluctuations of fashion, as well as social studies on cultural capital, and brand building. The study is made in a qualitative manner where the empirics consist of interviews with 13 respondents that have different positions in, and experience from the fashion industry, including designers, journalists, buyers, a CEO and a PR-professional. In our conclusion, we emphasize the need for a balance between cultural and economic capital in order to succeed as a fashion designer.
Värmepumpars inverkan på elkvaliten
Modern technology and fast development of heat pumps, the hunt for savings in energy consumption and the strive for environmentally friendly energy sources, convenience, and financial profit, have made heat pumps a reasonable alternative for the heating of houses.When the heat pump starts it will consume a considerable amount of current, which may result in a short-lived voltage-drop if the power grid is weak compared to the start-up current.The company Fortum Distribution which owns and administrates electrical network is interested in an investigation that deals with heat pumps affect on the quality of electricity.The purpose of this investigation is to study fast electrical fluctuations (flicker) as a result of start-up currents for single as well as multiple heat pumps on the same electrical station and from this evaluate whether there will be any problems installing heat pumps..

Recidivmönster hos glioblastom
Syfte: Identifiera recidivmönster hos glioblastom samt studera betydelsen av erhållen stråldos beträffande uppkomsten av recidiv.Metod: 50 patienter som strålbehandlats för glioblastom valdes ut till studien och deras magnetkamerabilder från uppföljningen jämfördes med behandlingsplanen frånstrålbehandlingen. Lokala, marginella eller distala recidiv identifierades baserat på om recidivet låg innanför, tangerade eller låg helt utanför PTV (planning target volume). De marginella delades in i två grupper, de som hade en fysisk koppling, connex, till GTV (gross tumor volume) och de som inte hade det. Vidare lästes erhållen stråldos i recidivet ut från strålbehandlingsplanen.Resultat: 35 stycken patienter hade fått recidiv på 42 unika lokaler. Av dess 42 recidiv var 66,7 % (28 stycken) lokala, 9,5 % (4 stycken) marginella med connex till GTV, 19 % (8 stycken) marginella utan connex till GTV och slutligen 4,8 % (2 stycken) distala.

Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.
Timmersorteringens inverkan på sågverksekonomin :
Modern sawmills are using the raw-material and the production-capacity more efficiently
today, due to rising raw-material prices and higher production costs. Log sweepness has a
negative effect on the sawn yield, for sawmills with straight-sawing. It is desirable that these logs could be sorted based on more criteria, if it increases value-yield and consequently the utilization of raw-material.
Bow-heights over 1 cm have a negative effect on sawn yield, since the surface of the
mantle cuts down in the sawn pattern. Some of these small bow-heights reduce the logs yield of value which affects the production planning negatively. Nearly half of all the Swedish logs have a bow-height over 1 cm.
Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd
The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.
Gallring med vinkelkran : en jämförande studie av skördarkran med och utan horisontellt ledad vipparm
One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands.
The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.
