Har ökad öppenhet påverkat den automatiska stabilisatorn? : -en makroekonomisk paneldatastudie
This paper investigates the automatic stabilizer and the underlying factors behind its function. The paper includes both a literature review and an empirical analysis. The literature review discusses the IS-LM and Mundell-Fleming models and different ways to quantify the automatic stabilizer. Based on the theory, the relationship between volatility in GDP and the size of the automatic stabilizers is then analyzed with the help of regressions. Our main result shows a negative relation between these two variables.
Hur tillgänglig är staden? : fallstudie av Kungsgatan och Föreningsgatan i Malmö
How accessible is the city? Is there more factors than merely the strictly physical that affect how accessible the city is perceived? These questions are the starting point of this study. The greatest emphasis, in this study, is placed on the perceived parameters that affect us humans when we move in our cities. Experiences and internal images can change our behaviour and prevent free movement in the city. The result from this study shows that a city can not be seen as fully accessible unless both the physical and the perceived accessibility are fulfilled.
Försäkringsbolags kostnader för reparation av fuktskadade badrum
The purpose of this report is to compile and examine the cost of renovation of moisture-damaged bathrooms, to derive a target price. The target price can then be used by insurance companies to estimate the ultimate cost of future bathroom renovations. The method is based on the compilation and comparison of the cost of repairs of previous water damage in bathrooms. The calculations compiled based on repair estimates for different insurance losses from one of the leading insurance companies in Sweden. The result shows the average price per square meter of floor area for different sizes of bathrooms. The average price is the basis for the estimate of future renovation costs of bathrooms. The results further show that the bathroom finishes, area and the distance between the entrepreneur and the location of the renovation have great impact on the final repairing cost.
Passivhus med prefabelement : En jämförelse mellan en platstillverkad konstruktion och prefabelement från Masonite Lättelement AB
This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..
Veingeskolan F - Undersökning av inomhusmiljön samt en konstruktionsmässig utvärdering
Title: Veingeskolan F - Investigation of the indoor environment and a structural analysisMethod: Complete analysis of structural drawings to determine if the school have been constructed correctly. In my teorethical studies of the drawings I must seek out points that may have been damaged from moisture, this contains a full survey of the foundation, walls and ceiling. To strenghten the data collected from the drawings I must visit the school and do field investigations to find out if the school has any problems with the indoor environment.Analysis: I determined that we had some damages on specific places, these damages was caused by leaking roofs, a carpet that was tarnished by strong sunlight in connection with some type of glue and also the ventilation that may have been drawing malodorous air from a shaft in the foundation.Conclusion: I was able to see that the decision to demolish the school was quite drastic, if the county would have done continuous fixups on the construcion when the employes had complained maybe the action to the tear the school down would have been unnecessary. The lack of communication between the two parts lead up to the decision to demolish and build a complete new school..
Mätning av partikelmassa i avgaser från en dieselmotor
This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.
Ny konstruktionslösning och kostnadsförslag för stansverktyg
The task for this thesis is to design a tool that is used to cut-out preforms of thermoplastic adhesive and also to make an estimate of costs for the stamping tool. The tool is used in the repair process at the MCM production line.
The result of gathered information has affected how the design of the stamping tool has developed. The handling of thermoplastic adhesive in the repair process is one of the factors that influenced the design. The adhesive is sensitive for exposure to moisture. Therefore an automated feeding system of the adhesive is not recommended.
The users wished for an automated stamping tool.

Smarta Hus: Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of
"Intelligent Houses", and most important- explore some of the future
possibilities in this area.
The project has been carried out through an interdisciplinary cooperation
between three different educations at the Blekinge Institute of Technology.
By conducting a dialogue with various actors with different professions, we
have been trying to identify needs within the concept of "Intelligent Houses",
were the end user is not only the tenant or homeowner.
Through Participatory Design methods, such as a Future Workshop, we have
brought the users together to discuss their own and each others needs and
hindrances in their respective work practice, and how intelligent house
technology could improve their work conditions.
We have also been testing a highly sophisticated
CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally
developed for regulating indoor climate systems.
Based on the needs we have found in our fieldwork, we have been looking at
possibilities to make multi user solutions with the sensor..

Inverkan av tvång i gjutfogar och i betongkonstruktioner på
elastiskt underlag: Influence of Restraint in Casting Joints
and in Concrete Structures on Resilient Foundation
In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.
Return Behavior of Initial Public Offerings and Market Efficiency
This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.
Undersökning av modulationsscheman för existerande bredbandsteknologier
In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
