Analys och förbättring av en mätenhet för laddning av elfordon

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.

Balanserat styrkort : Att förmedla vision och strategier inom divisionen för flygtrafiktjänst vid svenska Luftfartsverket

The purpose of this essay is to investigate how well vision and strategies communicates from division level to underlying business unit levels with focus on the Balanced Scorecard Concept. The investigation was carried out within the ANS division and two of its underlying business units at the LFV Group (Swedish Airports and Air Navigation Services). ANS is responsible for the air navigation services in Sweden and the production of the services is carried out of the business units AER (En Route) and ATA (Tower and Approach). With Air Navigation Services means supervision and conducting air traffic mainly within national air space. The purpose of the services is to insure that air traffic could be carried out in a safe way.The Balanced Scorecard was introduced for the first time in the beginning of the 1990´s.

This rapport aims to examine the difficulties in presenting a complex game in a way that will invite new players by making the game more accessible. We discuss and present our process on how to create an application named ?Digi?-war that is easy and fast to, both, learn and use. Our solution to this issue includes RFID-tags and readers together with four buttons, as input devices. This simple input device, placed in a gun-type control unit, aims to provide an intuitive interaction..

Informationsfrihet och IT-användning i demokratifrämjande syfte

The potential of information technology as a means to invigorate democratic practise is constantly under discussion. Regardless of the differing opinions as to the most suitable way to utilise IT, there are certain democratic core values that have to be considered. One of these is freedom of information, defined by us as the right of every citizen to seek, obtain and express information. The aim of this study is to explore whether the use of IT as a means to enhance democracy can strengthen the citizens right to freedom of information. As an instrument for analysis we use an article by Jan van Dijk, professor of communication science.

Investeringsprocesser i storbanker : en undersökning på tre svenska storbanker

There are no general working processes that can stand for how all the investment process is preceded in the organization of major Swedish banks. It is not a question of investment process but rather a question of, investment processes. How these investment processes operates depends totally on the type and size of the current investment, which unit that is operating the processes and what situation the bank currently finds itself in. There is a written form that describes how the different processes should be operated and which capital budget models that should be used but the usage of these forms can be questioned..

Sortimentsinriktad avverkning

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Ett hem eller två hem: hur vuxna skilsmässobarn tolkar och beskriver sin uppväxt mot bakgrund av den boendeform de vuxit upp i efter familjeupplösning

The break up of the family unit leads to new living arrangements and significant changes for children. This can be an extremely upsetting experience for a child, especially if the child is old enough to understand what is happening. New living arrangements can effect a childs fundamental sense of security as well as having consequences later on in life. The object of this research paper was to examine how a group of seven people (children from split families who are now adults), interpreted and described their childhood in relation to the living arrangements they grew up with after the breakdown of the family unit. The main question areas we have examined are: How have the interviewee's living arrangements during childhood affected their understanding of themselves today? In what way has the adult's present day lifestyle been influenced by the split up of the family that they grew up with - using their own words? How do the children from split families describe and interpret concepts such as family and marriage, based on their own experiences? Our research was conducted with the help of seven people from split families who are now adults and who experienced different types of split family arrangements as a child ? permanent residence with mother/father or alternate living with both parents.

Hur uppnår vi god inomhusmiljö i förskolan idag?

Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.
