Energioptimering av Hemsö fästning med förslag på energieffektivare systemlösningar
The report is a master thesis about energy efficient measures for an underground facility Hemsö fortress.Several proposals are evaluated economically.Statistics of the electricity used and measurements of several heat pumps are analyzed to find energysavings potentials.The results indicate that several units of a dehumidification system are responsible for over 70 % of theyearly electricity cost. The air that is being dehumidified by these units can otherwise cause damage ofculturally important interior designs.The proposal with highest profit suggests an alternative method for dehumidification. The cooler in theair handling units in Hemsö fortress have capacity to dehumidify the air. However complementary fansneed to be installed to circulate humid air towards the air handling units. The solution can be implementedin three different locations within the facility.
Förändring av radiocesiumtillståndet i jordbruksgrödor i Gävleborgs, Västmanlands och Uppsala län efter Tjernobylolyckan samt en fallstudie med stallbalansberäkningar på en mjölkgård :
Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely. When radiocaesium decays to a stable end product ionizing radiation is emitted, which can cause cancer in humans that has been exposed to a high radiation dose. Radiocaesium behaves like potassium and is easily taken up into biological systems.
Copingstrategier under uppväxten och senare i vuxenlivet för individer som har funktionsnedsättningen ADHD
The purpose of this study was to examine the differences and similarities between coping strategies used by individuals with the disability ADHD in childhood and later adulthood. The questions we asked ourselves: Are the individuals using the same form of coping in adulthood as in childhood? What copingstrategies used individuals while growing up? What coping-strategies used the individuals in adulthood? To fulfill the purpose and answer the questions, we used qualitative methods. Interviews were conducted with four adults who have the disa-bility ADHD. The interviews were analyzed by the hermeneutic circle.
Skuldlättnader som vapen i kampen mot korruption? : Om hur HIPC-initiativet påverkar korruptionsgraden i berörda länder
This paper examines how debt cancellation, given under the HIPC-initiative, has affected corruption over the period 2000-2006. The examination is foremost interesting due to earlier research showing that high corruption leads to unequal distribution of economic resources. This, combined with the objective of the HIPC initiative to reduce poverty, indicates that combating corruption must be successful in order to fulfill the goals of the initiative. A linear regression shows that countries that have benefited from the HIPC-initiative indeed have a lower corruption than other countries. A panel-data analysis shows on the other hand that no effect on corruption due to debt cancellation or reforms undertaken in the program can be confirmed..
Bränsleceller som applikation i bilar : Enstudie av Fuel Cell Electric Vehicles och deras potential för framtida kommersialisering
Användningen av personbilar har ökat stadigt i Sverige och världen i stort de senasteåren, vilket lett till ökade utsläpp av koldioxid. Samtidigt har oljepriset nåttrekordnivåer, och många menar att utvinningen av olja redan har nått sin topp. EU hardessutom satt som mål att medeltemperaturen på jorden inte får stiga med mer än maxtvå grader Celsius, och att till år 2050 reducera koldioxidutsläppen med 80 %. Detta ärenbart möjligt om nya, gröna drivmedel och drivlinor fortsätter utvecklas ochframförallt kommersialiseras. Användningen av förnyelsebara energikällor har ökatkraftigt, vilket skapat förutsättningar för bilar drivna av el.
Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon
The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.
Miljöanpassad offentlig upphandling: effektivt styrmedel mot koldioxidutsläpp? : En studie av kostnadseffektivitet, transaktionskostnader och teknisk utveckling
Green public procurement (GPP) can be used as an instrument to reduce carbon dioxide emissions, and consideration of environmental aspects within public procurement is becoming more common in Sweden and internationally. Two product groups that have been pointed out as especially important are transports and electricity, where the opportunities for public purchasers to reduce emissions are relatively large. This paper studies GPP which aims at reducing emissions, primarily of carbon dioxide, through environmental requirements within these two product groups. A theoretical analysis of cost-effectiveness, transaction costs and effects on technological development is performed, followed by a closer study of how these aspects appear in practice within GPP.
The results indicate that a cost-effective allocation of reductions between the two product groups is most likely to be attained if the main part of emission reduction is achieved through environmental requirements on electricity. The cost for emission reduction within transports is relatively high, especially for heavy transports.
For transportation services, more generally focused requirements on emission reductions could probably give greater environmental gains, but the existence of transaction costs steer the environmental requirements towards more technology specific types.
Emotionella upplevelser och emotionsreglering i samband med en nedskärningsprocess
The aim of this study was to investigate emotions and emotion regulation of a downsizing in an industrial company. The sample consisted of persons who had experienced a downsizing but have kept the employment, within a same position or being transferred to another one. Data consisted of two focus group interviews, analysed by an inductive thematic analysis. The results have indicated that emotional reactions changed over time as well the emotional regulation did during the different phases. The groups differed in emotional reaction related to the time of decision regarding the retention of employment.
Produktionsplanering av tvättmaskiner
Most major companies today have a visual identity. It answers questions like: which font do I use? and when can I use the logo or not? Westinghouse Nuclear Fuel in Västerås have a visual identity but no guidelines for the employees to follow. Further-more, rollups and rollup handouts produced by Westinghouse are not mentioned in the visual identity. ?erefore the external information from Westinghouse is someti-mes, both by employees and customers, perceived as not uniform.
Självförvaltningens effekter i vår gemensamma utemiljö
When we, in the turn of the year 07/08 moved to Holma, Malmö,I and my cohabiter immediately joined the self-managementon our tenement yard, partly because we both missed havinga garden since we moved to an apartment, partly becauseof the rent reduction. The aim with this thesis is to examinehow the common outdoor environment in tenement yards isaffected when the tenets themselves are responsible for themaintenance. But also to see what social affects self-managementbrings. The purpose is to increase the understanding of howself-management works in practice and how we as landscapearchitects need to adjust ourselves and our design to create alasting design that works when the tenets are in charge of theirown outdoor environment.I have been studying a number of tenement yards with selfmanagement,both municipal and private tenement houses. I havestudied both their design and their self-management, how it isworking and how it is organized partly trough deep interviewsand also by questionnaires to the tenets of the yards in question.I found three tenement yards with some differences.
Uppföljning av byggskadeutredningar i syfte att utveckla utredningsmetoden
Pappersmakulatur uppstår i tryckpressarna, men orsakerna finns i företagets alla funktioner. För ett framgångsrikt förbättringsarbete med att minska makulaturen krävs därför att all personal är engagerad.Examensarbetet utfördes på Bobergs Tryckeri AB i Falun, ett familjeägt företag med 60 anställda, som producerar personifierad direktreklam och blanketter. Syftet var att undersöka hur pappersmakulaturen kan minska och målet var att hitta orsaker samt ge förslag på åtgärder för att minska den.Genom intervjuer med personalen kartlades produktionssprocessen och utifrån det utarbetades förbättringsförslag. Exempel på förbättringsförslag är att kontinuerligt mäta och rapportera makulaturen, förbättra kommunikationen mellan avdelningarna och utveckla färgstyrningen. Litteraturstudier och kontakter med nyckelpersoner inom branschorganisationer och andra liknande företag, var till stor hjälp i arbetet.

FN:s Milleniemål och deras påverkan på den svenska biståndspolitiken
The purpose of this thesis is to study to what extent the UN millennium development goals have influenced Sweden?s development policy. The research method that I have used is a qualitative text analysis and I have studied the ideas in governmental texts and millennium development goals reports from 1995-2008.My hypothesis is that the basic ideas that has symbolized Sweden?s development policy has not changed much since the adoption of the millennium development goals in year 2000. This hypothesis is based on different ideas that the basic perspectives in international development policy are rather constant.My conclusion is that many of the areas that are affected by the millennium development goals already are prioritized areas within Swedish development policy, for example poverty reduction and gender equality.
Är Lerbodaälven verkligen en problemälv? : undersökning av fosforhalter
Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report.
1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven?
The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.
Testdriven utveckling (TDD) ? En metod för att minska underhållskostnader i mjukvaruprojekt?
The maintenance phase within software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.
