Solavskärmning med solceller och dess inverkan på energianvändning och inneklimat
In this thesis an explorative study was undertaken with the aim to study how a number of private care providers, as well as politicians and officials from councils in and around the Stockholm and Uppsala counties, think about the future of the Swedish elderly care from a property perspective, i.e. homes for the elderly. The analysis shows that there is a demand for capacity in 6 out of 16 municipalities, and that the property is an important part of this capacity, and the fulfillment of it. This was mainly due to the cost of capital, but also because of several other factors such as lack of land, a wish to guide the design, ideology, and in many cases a wish to use the property as an instrument of domination to control private health care providers.Also, the property was show to be connected to economic competition, to freedom of choice, and to quality. The problems related to the property in the market for elderly care still remains to be solved.
Bärförmåga i skjuvning för råspontpaneler. Laboratorietest och FE modulering
AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.
Analytisk dimensionering av räddningstjänst : fördjupad analys av insatsförmåga och täckningsgrad inom Räddningstjänsten Syd
In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.

Aktiv marknad: Nivåer av verklighet: - En fallstudie på svensk storbanks tillämpning av IFRS 7 och IAS 39, med avseende på fördelningen av finansiella tillgångar i level 1 och level 2
This essay examines the process of fair value accounting of financial assets in a Swedish commercial bank, in contrast to the theoretical approach stated by IASB. The theoretical background contains a review of the academic standpoint on fair value accounting and historical cost accounting, a detailed description of fair value accounting according to current and future IASB regulation and on the American FAS 157 regulation. The empirical case study describes the process of valuing and classifying financial assets into level 1 and level 2 of the fair value hierarchy. The analysis describes how the legal requirements for classification are interpreted and applied in practice when valuing bonds and derivatives. The authors provide an explanation as to why the majority of financial assets are valued mark to model rather than mark to market as well as a suggestion on how the share of market valued assets can be increased..
Logistik i byggbranschen : Fo?r fo?rba?ttrad arbetsmiljo? och effektivitet

Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.
Konsekvensutredning inför införande av koncerngemensam systemplattform : Vad skulle det innebär att införa SAP på KSU, Kärnkraftssäkerhet och Utbildning AB
The implementation of large IT-systems is a complex area where many aspects have to be taken into account.KSU, Kärnkraftssäkerhet och Utbildning AB, is a small company in the Vattenfall group that is increasingly being urged to implement SAP, one of the largest ERP-systems on the market. Vattenfalls purpose with SAP is to centralize certain processes within economy that are common to all the companies in the group, this to gain benefits with economics of scale. However, KSU is not convinced that SAP is a suitable system and that the common processes apply to them.The purpose of this degree project is to investigate if SAP is a suitable system and if KSU will benefit from a transition to SAP. Three perspectives were applied to further specify important areas of the main question. From a technical point of view KSU:s demands on a system was mapped against SAP.
Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE
The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.
"TV-spel är inga konstigheter!": En enkätundersökning om tv-spel på folkbiblioteken
The aim of this bachelor thesis is to investigate the lending of video games at the public libraries in Sweden. The thesis focused around a web survey, which was sent out to all public library directors, as its research material. The results were compared with those found in a master thesis by Olle Berg and Thomas Nyström from 2008. This was done to gain a better understanding of why the libraries provided video games. The other results of the survey were analyzed with a quantitative method.The results indicate that half of the responding libraries provide video games for borrowing.
Automatiserad konstruktion av analoga förstärkare
The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.
Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö
With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.
Effekt av grusmängd och vältning för spårbildning på grusväg
Nybyggnation och underhåll av skogsbilvägar medför stora kostnader för skogsbruket. Georadar (GPR) är en teknik som kan användas för att läsa av en vägs struktur vilket ger ett möjligt tillvägagångssätt för att reducera kostnader vid upprustning av vägar. Detta genom att endast partier med sämre bärighet rustas upp och därmed läggs rätt mängd material på rätt ställe längs vägen. Alternativet är dagens subjektiva bedömning av åtgärdsbehov och godtycklig placering av grusmängd.
Syftet med denna studie var att kvantifiera skillnader i spårbildning mellan 100 %, 75 % samt 50 % påförd materialmängd i överbyggnaden av total rekommenderad materialmängd för att uppnå bärighet motsvarande vägklass 3B, samt hur spårbildning i vägkroppen påverkas av vältning. Grusmängden för överbyggnaden dimensionerades med ledning från data insamlade med GPR och fallviktsmätare.
Förbättrat råvaruutnyttjande vid kvalitets-sortering av timmer : utvärdering av analysprogrammet Stockholmen för automatiserad timmersortering i dimensions- och kvalitetsklasser hos BARO WOOD AB
The aim of this thesis was to analyse BARO WOOD AB:s timber measuring and quality sorting and to evaluate the analyse program Stockholmen. The purpose was to get a better understanding for the quality sorting made at BARO WOOD AB today, analyse differences in center board quality from logs with a good quality and logs with a bad quality, suggest new sorting criterias developed from analyses made with Stockholmen and to evaluate the program Stockholmen. All analyses are based on data gathered in a test sawing made at BARO WOOD AB in June and July 2002. The test sawing was made on four different diameter classes and every diameter class consisted out of A or M-grade logs, with a better quality, and B-grade logs with a lesser quality. The logs where sorted out with BARO WOOD AB:s existing quality criterias.
Fel i produktionen : En studie om uppkomna fel i två anläggningsprojekt
AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.
Beräkning av energianvändning i svenska småhus
An energy calculation model for Swedish houses that is fast, flexible and user-friendly has been developed within the framework of this thesis. The model also provides a set of actions which may be investigated in the model based on savings and payback period. Energy use in a house depends on the technical conditions, such as building envelope and heating systems, which outdoor climate the house is exposed to and who lives in the house. Energy use for a house can be divided into heating, hot water and household electricity. There are several methods to calculate the energy use of a house. This report summarizes the methods that may be suitable for a fast and user-friendly calculation model.
