Uppsalahem is the leading housing corporation in Uppsala with its over 160 real estate properties. Uppsalahem is owned by the municipality of Uppsala, which has a climate and energy goal that aims for 100 MW of solar energy to be installed in Uppsala by 2030. The 100 MW goal, combined with Uppsalahem?s environmental policy, is a strong incentive to investigate the possibility of installing PV modules on the many available roof areas that Uppsalahem possesses. The objective of this thesis is to create a foundation for future decisions regarding PV systems for Uppsalahem.

Today we see a fast developing of the market for mobile communication, both in an increased and changed mobile use, but also in the development of new technologies and services. Much that can be performed on Internet/Intranet today with a PC will in some years also be possible to do with a mobile terminal. Mobile Internet will probable take place when new technologies as GPRS, EDGE and UMTS will be in use. These technologies in combination with the development of new terminals and services will bring new capabilities for both companies and private users. This report describes how a portal should be designed in order to meet the needs on the market.

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

This Master of Science thesis was completed at the Department of Machine Design at the Royal Instituteof Technology in Stockholm in collaboration with Lund Faculty of Engineering, Luleå University ofTechnology and Stanford University. At Stanford University a global product development project wasrealized as part of the course ME310. The project was initiated by the American company ImmerseGlobal whose vision was to develop a new type of Atmospheric Water Generators, a machine that absorbsthe moisture in the air and via a water system transforms it to pure drinking water. The project was partlyfinanced by the Product Innovation Engineering program, a Swedish research and development programfor increased innovation capability in organizations.In parallel with the global project in the ME310 course the product development process was studied inorder to compare it with a product development course at the Royal Institute of Technology, IPU. Thetwo courses are similar to each other in several aspects.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Bakgrund: Vi anser att en framtida utmaning är att bygga in en flexibilitet i den fysiska distributionen. Detta innebär att ett detaljhandelsföretag skall ha möjlighet att växla mellan att stundtals distribuera en och samma produkt via centrallager och stundtals direkt från producent till varuhus i förädlingskedjan, en flexibel fysisk distribution. Syfte: Syftet är att utröna förutsättningar för och konsekvenser av en flexibel fysisk distribution för de olika aktörerna i en förädlingskedja, i vilken detaljhandelsföretaget besitter en påtaglig maktposition. Genomförande: Empirisk data har samlats in genom en fallstudie i IKEA:s förädlingskedja. Resultat: En integrerad förädlingskedja med ett tydligt supply chain synsätt, i vilken samtliga aktörer samarbetar och har incitament till medverkan, utgör en förutsättning för en flexibel fysisk distribution.

The last hundred years humans have drastically changed the amount of available nitrogen in nature. Today human activities release twice as much available nitrogen as all natural processes are doing together. We also have degraded nature´s possibilities to take care of nitrogen through the draining of wetlands and straightening of rivers. In order to regain the potential of nitrogen retention in the water systems there now requires a reshape of the landscape we live in. A planned expansion of the mining activities in Garpenberg, Dalarna, would double the content of nitrogen in the waters below the mine.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Subject: Independent essay in War Science (15 points) which debate the question if PrivateMilitary Companies is an asset or a threat to the Swedish Armed Forces regarding rerecruitmentwith focus on the soldiers of FS21.That which is investigated is the general attitude amongst soldiers who have completed theirconscript duty according to the old conscript system and now is employed in order to conducta tour abroad with Afghanistan as area of operations. Further investigated is their attitudeagainst the Swedish Armed Forces as an employer, as well as the private sector whichwant/could benefit from the skills the soldiers is possessing. Could the soldiers se themselvesleave the Armed Forces before the contract has expired in benefit of private companies whichclaim they solve similar tasks.Purpose: The purpose with this essay is to contribute with knowledge about a number ofemployed soldiers? attitude against Private Military Companies. Further; if the soldiersbelieve the Armed Forces provide them as they think they deserve/ want in order to stay andnot leave their job in favour of PMC:s, and through it clarify what the soldiers value asemployees.Order of Approach, Method and Material: The method I?m using is a survey in whichsoldiers and squad leaders have answered the questions.

Background: Insufficient nutritional support is associated with prolonged hospitalisation, impaired wound healing and impaired survival for patients in intensive care. In severe sepsis and septic chock, calculation of nutritional need is complicated since the metabolism is affected by decease. Aim: The aim of the study was to investigate nutritional support and to examine the quality of nursing documentation of nutritional status and nutritional support in patient records in severe sepsis and septic chock.  Method: The study was conducted as a retrospective investigation where 64 patient records were studied. The quality of documentation was examined in 10 patient records using an examinational model.Findings: Calculation of average nutritional support showed insufficient supply particularly in the two first days of intensive care. During the next five days nutritional supply was higher but individual variation was seen, why a clear picture of nutritional support is hard to detect.

Social capital is a relatively new concept that has received considerable attention in various community branches. The concept relates to people?s contact and relationship with each other, where their social network is seen as a resource. An extensive network of contacts and trust between people often go hand in hand. People with high social capital have high trust in their fellow human beings and vice versa.

The concept of the dynamic region has become a more prospering thought in the era of globalisation. This concerns in particular, cross border regions ? well-integrated territorial regions crossing more than one nation. In this paper I examine the development from a critical perspective and I map the democratic pitfalls of new territorial political constructions across national borders. The empirical analysis is a case report taken from the Öresund region, a cross border region between Sweden and Denmark.

Due to global climate change and the rising levels of greenhouse gases (GHG) in the atmosphere, the interest for seeking solutions for mitigation has increased. While much attention has been directed towards technical solutions such as carbon capture and storage (CCS), biogenic carbon sinks has also garnered significant attention. Previous studies have shown that coastal ecosystems such as seagrass meadows and mangroves have a much greater capacity for storing carbon (C) compared to terrestrial ecosystems. That raises the question if other coastal ecosystems, such as coastal wetland forests, that previously haven?t been considered as blue carbon habitats also contribute to coastal carbon sink capacity.

With an increased empowerment of the users, and a dependence on outside critics, one wonders what kind of role the librarians have in a context where qualitative literature is discussed. The aim of this study is to examine the relationship between librarians private and professional views on qualitative fiction, in order to be able to discuss their role as quality intermediaries in a user oriented context.The method used, is the qualitative, semistructured interview. This author interviewed seven librarians from three different libraries in Sweden. The theoretical emphasis partly relies on the ten words of qualitative value that Inger Elam and Bengt Brülde discusses in their respective texts, partly on David Garvins quality assessment theory, which defines several quality categories divided between an absolute and a relative quality view.Through the comparison between the private and the professional quality view, examined with the two theoretical approaches, the analysis of the interview material shows that there lies a complexity in the librarians professional role. On the one hand, they are dependent of both the users and the critics judgements about the qualitative aspect in the work with purchasing new literature to the library.

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.
