Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).

A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.

The purpose of this study was to examine leadership in the public sector based on leadership models, organizational factors, conditions and health of employees. The study was divided into sub-study one and two. In sub-study one the design was an observational study using cross sectional design in which 67 first line managers in the public sector answered a survey about conditions and leadership models. Sub-study two was an observational study using case-control design focusing on a health promoting leadership intervention in the municipal sector. Two semi-structured interviews and 41 surveys were collected.

Previously studies have shown that the way companies explain outcome in their annual report is not totally trustworthy. Studies show that the management has a self serving bias when they explain the result to give a positive image of the company. Our study is based on investigations into this phenomenon in the telecom market in Sweden. Turbulent market conditions with, among other, deregulation of the monopoly of fixed telephony and a huge technical evolution, which has led to an increase in competition, is the reason to why we have chosen to study the telecom market in Sweden. As a benchmark in our study the attribution theory will be used.

Purpose of the essay: The purpose of the essay is to, from the view of the nurses working at the x-ray infirmary; see how the internal e-mail communication is working as the main digital communication method at the x-ray infirmary.Material/Method: The material has been collected using qualitative interviews with eight nurses working at the x-ray infirmary. The material has then been analyzed through a theoretical perspective based on The Media Richness theory.Main results: The results of the investigation have shown that the nurses see the internal e-mail communication as relatively poor. The information that is sent out by their superiors is often too extensive, this making the screening work an extra work burden. These e-mails are also supplied to the whole infirmary instead of being addressed to specific individuals. Seen through a media richness perspective, the e-mail is a mediumrich communication medium that well could be used in the everyday communication at the infirmary as the main communication agent.

Purpose: Corporate communication strategies have a central role in disseminating and creating meaning to the organizations? visions, strategies and goals. But many employees do not know the organization?s overall strategies and goals, nor how well the organization achieves these. The aim of this study was to investigate and describe perceptions about internal communication, primarily focusing on communication about strategies and goals.

The aim of this study was to explore how six men who run a micro-enterprisewith a maximum of 10 employees handle the balance between work and otherlife. Qualitative approach with semi-structured interviews was conducted and thesample consisted of six men with micro-enterprises of varying ages. The themesused in the interviews were boundless work, roles, boundaries strategies anddemand / control - social support. The results showed that micro- entrepreneursdo not experience any major imbalance between work and other life. The studyrevealed that the division of roles in the home of the elderly respondents was ofthe classical gender character that woman took great responsibility in the home.Among the younger respondents the unpaid work at home was equal divided.Social support was perceived highly by all respondents, and they alsoexperienced a high level of control over the requirements of the job.

This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.

To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

Syftet med studien var att belysa hur motivation på arbetsplatsen kan betraktas från ett inre och yttre perspektiv, med utgångspunkt från ett antal specifika faktorer såsom samhörighet, kompetens, autonomi och kontroll i tillvaron. 126 respondenter, 99 kvinnor och 27 män besvarade en enkät som bestod av demografiska frågor, frågor kring chefens stöttande av autonomi, frågor om samhörighet, kompetens och arbetsmotivation samt ett testbatteri bestående av IMI scale, Work Extrinsic and Intrinsic Motivation Scale och Locus of Control. Studiens resultat visar att chefens stöttande av autonomi påverkade de anställdas inre arbetsmotivation positivt. Studien visar även på att det finns ett svagt samband mellan inre arbetsmotivation och tillfredsställelsen av de anställdas behov av autonomi och samhörighetAbstractThe purpose of this study was to see how work place motivation can be seen from an intrinsic and extrinsic perspective, with starting point from specific factors such as relatedness, competence, autonomy and control. The 126 respondents of the study, 99 women and 27 men, answered a questionnaire that consisted of a few demographic questions, questions about if the boss is supportive of autonomy, questions about relatedness, competence and work place motivation.

SammanfattningDenna uppsats beskriver design och implementering av en mer effektiv metod att styrakameraförsedda radiostyrda markfordon (UGV av engelskans Unmanned GroundVehicle). Det åstadkoms genom att införa samma kontroller som är vanliga i actionspel iförsta persons perspektiv, så kallat Free Look Control (FLC). Miljontals spelare kommeratt känna igen och vara bekväma med styrprincipen, vilket borde reducera dengenomsnittliga träningstiden samt förbättra prestationsförmågan. FLC gör det möjligt föroperatören att kontrollera kamerans läge direkt istället för via fordonet den sitter på.Detta görs genom att i mjukvara sammankoppla fordonets och kamerans rörelser.Utöver författandet av denna uppsats byggs en fungerande UGV-prototyp som kanstyras enligt både FLC och dagens standard, Tank Control (TC). Detta gör det lätt attdemonstrera skillnader mellan metoderna.Arbetet utförs åt institutionen Flyg- och systemteknik inom FOI, Totalförsvaretsforskningsinstitut, för att demonstrera och marknadsföra konceptet att använda FLC förstyrning av obemannade markfordon.Nyckelord: Odometri, Kalman filter, UGV, Unmanned Ground Vehicle, obemannademarkfordon, FLC, Free Look Control, FPS, First Person Shooter, fjärrstyrning..

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

Background: In a world that are becoming more and more aware of the climate changes that occur as a consequence of the increasing emissions around the world companies? experience that the opinion blame the internal processors for this. Many companies feel forced to align their strategies to the environmental goals set by the community. Some of the emissions the companies? operations can be linked to business trips and it is therefore interesting to see how these can be reduced by using different performance measures.
