Att ta vara på solens fulla uppvärmningskapacitet

The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

Förändring av rädslans rum : med trygghetsskapande

This project has resulted in an website at www.tinadunker.se, where you also can download the project in it´s written form to get a deeper view of the project. This project aims to explore fear of violence in public places. Fear of violence reminds us that there is a problem in our urban environment that leads to spatial consequences in using public space. Many groups in our society experience fear in their everyday life but this project has focus on women?s fear.

Kombinerat system för ventilation och rumsuppvärmning : Parameterundersökning i simuleringsmodell för takvärmesystem

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

Janus två ansikten : En studie om kökslärarens dubbla roller

This is a field study based on participant observations and interviews, describing the cooking teacher's complex everyday life. The school's restaurant is a unique arena, freely hovering between two worlds: The school world and the restaurant reality. Here, the students are confronted with real situations and problems, similar to the ones occurring in a restaurant, still having the school's safety net beneath them. It is for real, but still not, a bit like a flight simulator.It is on that arena the cooking teacher works, combining the two roles of the teacher and the chef. Two roles built on their own traditions and values.

Klimatanpassning med grönstrukturplanering : Med exempel från Malmö stad

Climate change is expected to lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.

Stresshantering ur ett ledarskapsperspektiv

Title: How to manage stress seen from a leadership perspective Authors: Lina Jonsson, Kristian Olsson, Mattias Olsson, Shabnam Tahajjod Supervisor: Marie Aurell Department: Department of Business Administration, IEM Course: Bachelor thesis in Business Administration, FEC 007 Question of issue: How can we understand stress managing at a workplace seen from a leadership perspective? Method: We have chosen a qualitative method for our thesis with inter-views as qualitative data collection. The interviews had a low grade of standardization. Result: On the basis of our question of issue we have drawn the con-clusion that it is important to create comfort at the workplace, that there are a safety and a feeling of handle the work tasks and that there is a plentiful information flow between managers and employees to manage to handle the workplace stress situa-tion..

Mobilt internet för skogsbruket med CDMA2000 i450 MHz - bandet :

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

Skjuvhållfasthet och deformationsegenskaper för Uppsalalera med CRS och standardödometer

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Hur uppfattas riskinformationsbroschyrer? - teoretisk analys och experimentell studie av riskinformation

Information about the risks involved shall be distributed to the people living in the area nearby to potentially dangerous installation. Swedish law stipulates strict requirements on what information should be supplied, but the law itself does not give any guidance on presentation. The main purpose of the study is to give recommendations on how to improve the information brochures. Within the study, eight people working with risk information have been interviewed and seven different risk information brochures have been studied. Also, a theoretical analysis and a practical experiment were performed using brochures from two municipalities.

Utveckling av reglersystem till quadrokopter

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

Modell för värdering och hantering av avbrottsrisker vid kontinuitetsplanering (BCP) : Fallet Swedwood

This master thesis presents a Model for Evaluating and Managing Interruption Risks in connection with Business Continuity Planning (BCP), developed for Swedwood International. The model consists of a template with instructions. The model should be easily understood and useful for establishing a plan for BCP. This is achieved by including the contents and procedure of BCP and the main supplychain risks in the model. The purpose of a BCP plan is to describe how an enterprise will return to business as usual after an interruption, e.g.

Motorsågskörkortet - en utvärdering av Skogsstyrelsens motorsågsutbildning vid Frossarbo kursgård 2005 - 2007 :

The use of chainsaws in both private forestry and commercial companies is highly associated with personal injuries and accidents with deadly outcome. As a result to this, a driver?s license for chainsaws was presented in the year 2005. To get the license you have to attend a course given by the Swedish Forest Agency or one of several private educators. This study is an evaluation of one course given by the Swedish Forest Agency in Uppsala.

Framtidens elnät : Hur elbilar och solceller påverkar på det lokala elnätet

The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.

Cykelplanering ur ett studentperspektiv : En studie om trafiksäkerheten i centrala Uppsala

I norra London startade, den sjätte augusti 2011, ett av de största upploppen i modern tid. Syftet med denna teoretiska uppsats är att - inspirerat av londonupploppen - diskutera olika teoretiska sätt att förklara och förstå händelserna ifråga, med särskild fokus på relationen mellan strukturellt och direkt våld. Styrande teman är socialt utanförskap, skam och vanmakt. Analysen indikerar att det sociala utanförskap som strukturellt våld och relativ deprivation skapar är grogrunden för vanmakt och skam ? två känslor som är intimt förknippade med direkt våld.

Hardware-in-the-Loop simulering av motorservon på ett inbyggt system

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.
