Nedläggningen av Bahco-fabriken : En lokalstudie av tre aktörers argument och agerande

The purpose of this study has been to investigate how individuals with reading- and writing disabilities and dyslexia handle their information need in the workplace. The method that has been used is a qualitative study made with interviews with individuals who have these problems, to see how they think and feel about the flow of information on their everyday basis. The study?s respondents are working women between the ages of 27 and 47 years old and they have reading- and writing disabilities and dyslexia. The most interesting results of this study are that the respondents are avoiding jobs where they need to read and write much and where they also do not like changes in their job situation.

Mikroproduktion av solel i flerfamiljshus : Lönsamhetsanalys genom simulering av solcellsanläggningar och explorativ kundundersökning

This thesis is commissioned by the Swedish electricity trading company GodEl with the purpose of evaluate solar electricity in multi-family buildings in the Stockholm region. The prices of solar panels have dropped recently due to the advances in technology, but the installation rate in Sweden remains low. It is therefore interesting to study the  profitability of solar electricity today, and if it is profitable enough to install based on profitability alone and not simply due to environmental considerations. Therefore this thesis first studies the profitability of solar panels based on a simulation of electricity production and consumption for multi-family buildings this region. The study concludes that solar electricity can be profitable in the Stockholm region under certain conditions; all of which have to be favourable for profitable solar electricity.The thesis also studies the opinion of the company's costumers concerning solar electricity.

Kv. Tvättstugan, ett flerbostadshus med massiv trästomme : Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter

Title: Kvarteret Tvättstugan, an apartment building with massive wood construction. A thesis about acoustic and fire requirements and a comparison of energy and moisture aspects. Earlier restrictions in the Swedish legislation have resulted that only a small percentage of the apartment buildings that have been built are designed with a massive wood construction. It has been allowed to build unrestricted with wood since 1994 as long as the function of requirements are fulfilled. This change in the rules together with the great environmental benefits of wood has led to that more companies choose to build apartment buildings with wood. One of these companies is Folkhem Production AB.

Utvärdering av simulationsträning - finns det evidens för lärande? : En litteraturstudie

På uppdrag av Kliniskt Tränings- och Simulerinscentrum (KTC) kom författarna till denna studie i kontakt med ämnet simulationsträning. Simulationsträning introducerades under 50-talet i den medicinska världen. Sedan dess har det gjorts många framsteg och förbättringar på området, i takt med att kraven ökar på sjuksköterskans arbetsuppgifter. Syftet med den här studien var att studera effekter av simulationsträning. Studien baseras på tio vetenskapliga artiklar vilka behandlar simulationsträning och dess effekter.

Ett kärleksbrev till hantverket

Where is technology heading? And how will our behaviors towards these new innovations look? This project questions the direction of ?beyond smart? products, through scenarios within our everyday life. The work is both critical and speculative. Speculative in the sense that it is speculating in how a future scenario with ?beyond smart? products would look like.

Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde

The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..

Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Renovering av flerfamiljsbostäder inom miljonprogrammet ur ett energi- och lönsamhetsperspektiv

Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.

Effektivisering av produktionsflöde : Införande av ny teststrategi

Ericsson AB in Katrineholm is a part of the Section Business Unit Network in the Ericsson Group. The plant's main task is to produce printed circuit boards in small volumes with a high product mix and focus on delivery and cost effectiveness. At the factory they produce printed circuit boards in the Module department.The Module department has for a long time had a high output of non-approved circuit boards in their production. This has led to a growing stock of non-approved circuit boards on the company?s repair department.The purpose of this thesis is to investigate how Ericsson in Katrineholm can increase the outflow of approved articles in their test process in the Module department.

Studie av integration mellan rategyron och magnetkompass

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

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.
