Detta arbete behandlar problemområdet systemförvaltning och är en vidareutveckling av förvaltningsmodellen vid systemförvaltningsprocessen. Vid systemförvaltningsarbetet finns det olika förvaltningsmodeller som kan vara ett stöd vid taktisk och operativ styrning samt administrativ kontroll.Systemförvaltningsmodellen består generellt av sju olika rekommenderade delmodeller där bland annat systemförvaltningsprocessen ingår. Modeller för systemförvaltningsprocessen bör förenkla, effektivisera och ge stöd när systemförfrågningar samt systemkrav inkommer från verksamhetsledningen eller systemanvändaren. Undersökningen i detta examensarbete fokuserar på en vidareutveckling av modellen Application Maintenace Cycle (AM/Cycle) som utvecklats av Peder Brandt.Vidareutvecklingen i detta arbete resulterar i en modell för systemförvaltningsprocessen, vilken benämns Application Maintenace Schedule Cycle (AMS/Cycle). Litteraturstudier och intervjuer har påvisat vissa svagheter med modellen AM/Cycle, vilket tagits i beaktande vid vidareutvecklingen av AMS/Cycle.

The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.

With recent technical development computer aided design and manufacturing has taken amore important role in the product life cycle. New business segments such as Product/ServiceSystems and remanufacturing is emerging. This development demands better control of theproduct data throughout the entire product life cycle. Computer aided design is widelyrecognized and used within the manufacturing industries and in recent years the importance ofDigital manufacturing has increased. One part of Digital manufacturing is paperlessproduction which involves all orders and working instruction shown for example on a screenrather than on a piece of paper.

The goal with this examination thesis is to investigate the difference in carbon dioxide emissions between a building with a wooden versus concrete carcassing from a life cycle perspective. The huge amounts of carbon dioxide released into air from human activities must be reduced to prevent serious consequences. A way to limit this issue is through performing a comparative study where the result shows which of two products with the same function has the lowest emission of carbon dioxide, whereof the product with the lowest carbon dioxide pollution can be chosen.To be able to perform a study like this an object has been chosen and studies about life cycle analyses have been done. The rental square meter, the thermal conductivity value, the energy requirements and the placement of the building has been set equal in both framework types. There were solely dissimilarities of the two buildings taken into account when this comparison study was performed.The result of the study is that a building constructed with a wooden carcassing has the lowest amount of carbon dioxide emissions.

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

This report analyzes disposable packaging and returnable packaging with the methods life cycle analysis and life cycle costs analysis. These two different packaging are analyzed through the company Clas Ohlson?s packaging-flow. To get a picture of how the flow works, a visit at the company and email contact have been done with Clas Ohlson to get relevant informationToday Clas Ohlson has a big flow of articles to the stores without larger variations in the demand, with the exception of autumn, which is when customers start shopping for Christmas. Clas Ohlson?s articles are placed on a pallet and are wrapped into plastic-film for protection and to make sure that nothing will be stolen.

The cell cycle is the time a cell spends between two cell divisions. The cell cycle includes several parallel processes, all of which must be completed before a cell is mature for dividing. In the first place, all subcomponents (RNA, protein and membrane lipids) need to double in quantity and this occurs continuously through the cell cycle. Furthermore, the genome and some chromosomal proteins must double and this take place during a limited interval in the middle of the cell cycle (S-phase). On either side of the S-phase are two "gaps" which is called G1 and G2. When the cell has passed a point in the G-phase they are irreversibly programmed to progress through the remaining of the cell cycle and will undergo the next cell division. When a cell have passed a point in the G1 phase, approximately four hours after mitosis, a normal cell is in a state of indecision.

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.

This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.

Introduction: Studies have shown that women are not always satisfied with the effects of contraception and that contraceptive advice is perceived as non-specific. Aim: The purpose of this study was to investigate what contraceptive women have chosen to use in the different phases of their reproductive lives, and what they felt had influenced their choice. Method: A retrospective cross-sectional comparative study with a quantitative approach. A survey with fixed and multiple-choice options was sent to five hundred 45-year old women. Result: The study shows that various birth controls are different in the normal reproductive life.

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.
