Energibolagens framtida datainsamling
The Swedish energy companies have several different systems for data collection
of the energy consumption of their clients. Often computerized remote meter
readers are put in practice in order to register the energy consumption of
large companies. The majority of household clients, however, are read off by
the assistance of manual methods.
Household power consumption is read off once a year. As a result, these clients
are not debited for their actual consumption; their invoices during the year
are the result of estimations. At times when the electricity supply system is
highly loaded, electricity is more expensive.
Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm
When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
Outsourcing av UAS-data : Informationshantering av data insamlad viaUAS
This reports purpose is to give a general view on how to handle information collectedthrough photogrammetry and laser scanning with the help of UAS. The report ismade in collaboration with WSP Group and will briefly describe howphotogrammetry and laser scanning, also known as Lidar, works and how those areused in the construction business today. Then the focus will be on how gathered datais handled today, how outsourcing of data should be approached and if there are anyconsequences if data is handled in the wrong way. Interviews have been made with allparts in the UAS business. That includes authorities as Transporstyrelsen,Försvarsmakten.
Miljöbetong
The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.
Att genom fiktion skildra en verklighet : En kvalitativ studie i hur maktstruktrurer beskrivs i BBC:s tv-serie The Hour
The objective of this study was to investigate how power relationships between journalists and politicians were shown in the fictional BBC tv-series ?The Hour?. We wanted to investigate how these power structures is narrated by the producers of the series and what impact the narration could have to the audiance of the 21th century.We choose to analyse a total of 12 scenes from all of the six episodes, which are all set in Britain during the beginning of the Suez Canal crisis in the 1950?s, all seen from a BBC editorial point of view.In our analysis we chose to use two different kind of methods, the first one was a situation analysis and the second one a text analysis. The situation method was useful to get a perception of the relations between the participants .The text analysis we used to analyse what was said in the tv-series and to interpret underlying motives.The fictional form necessitated a personalization of power structures, in the sense that each and every power was represented by a single character; political power was for instance represented by the character of Angus McCain.
Utvärdering av produktionsledarens användning av Holmen Skogs datorbaserade stödsystem vid operativ planering av avverkning
The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems.
The aim of this study is to:
? investigate the work pattern of the production managers when using the information system to plan the harvesting operation;
? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system;
? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern;
? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion.
The conclusions of the study were:
? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning;
? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information;
? the computer systems are however divided in many subsystems.
Ledarskapsutbildning ? till nytta eller nöje för Kommunstyrelsens ordförande? : En uppsats om betydelsen av ledarskapsutbildning
Many IT projects that have been developed in recent years are often considered to be unsuccessful. According to a study by Exido up to the 72% of all IT projects are considered to be failed. A failed IT projects means that the organizations that have ordered the new system may have higher costs or/and the system will not be ready in time. If costs are too high the new system might not be installed in the organization or if the system is not completed within the specified time frame the organization can become stagnant.In this paper we conduct an investigation of the failure of IT projects there we will examine where, in the systems development lifecycle four different phases, projects fail. We will conduct an empirical study of each phase, where we describe the key steps in the process; we will also investigate failed IT projects that are linked to the current phase.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work
effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of
the feeding can be very simple or include high degrees of mechanisation.
Three different farms, representing different levels of mechanisation are presented.
Descriptions and analysis of the feeding systems including mechanisation, work effort and
estimations of the feed waste are made on each farm. The herd with the most advanced feed
mechanisation included a rolling feed band and mix wagon. The other farms were partly or
little mechanised including ad lib feeding from big bales and manual distribution of hay and
concentrates.
The most mechanised farm was able to feed a large herd of sheep at a low work effort and
little feed waste. However, the investment in machinery has to be weighed against the
improved efficiency.
Comparison of three IVC systems for mice, with focus on growth and nest building in juvenile mice
Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.
Projektdokumentation : Kritiska framgångsfaktorer
Projects of all kinds generate documentation that needs to be organized and stored for future use. Well adapted tools, together with a unified modus operandi need to be available for both the project members and those having a more organizing role if an organization is to be effective.A study of the tools available to project members at Svenska Kraftnät have been performed along with an analysis of the guidelines for the tools' usage. The study has focused on the needs of the project members, not the organization as a whole, thus providing a bottom-up approach to the problem instead of the more organizational top-down approach. Interviews of around 20 project members, whose roles include project leaders, technical experts and documentation supervisors, have been conducted to get an idea of the practical problems that exists.All systems, except for a local network storage device, were found to at least meet Svenska Kraftnät's current demands. The usage guidelines, however, covers only the general process that a project should follow and lacks detailed information on a per system level in several areas.

The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.
Är sexsäljare offer eller har de fattat ettmedvetet beslut? : En diskursanalys av svenska tidningsartiklar
This study is a critical discourse analysis of Swedish newspaper articles about prostitution. The purpose of the study is to investigate which discourse/discourses about prostitution that is/are adressed in the articles and identify the power relations and meanings that are constructed by the different subject posititions in the articles. Apart from critical discourse analysis social constructionism and a discussion about gender are applied in the analysis. The results supports findings in earlier research about prostitutionin Sweden; that the debate is focused around prostitution as sexual domination or prostitution regarded as a voluntary choice which rises demands of human rights for sexworkers. No prostitutes or buyers of sex where given the opportunity to comment on the matter, only journalists, politicians, social workers and policemen.
Betydelsen av förändringar i DuPont-komponenterna för framtida operativ lönsamhet
The DuPont formula is one of the most well known and basic tools used for financial statement analysis and is highly useful for understanding firms strategies and operating environment. Previous studies on American listed companies have also shown that analysis of the changes in the DuPont components is useful in forecasting contexts. In this thesis we test whether disaggregating the change in return on net operating assets provides incremental information about future performance for Swedish listed and not listed companies. We find that the change in asset turnover is a leading indicator of increased profitability for both listed and private companies, regardless of size. We also find evidence that the usefulness of the disaggregation for understanding future performance is greater in capital intense industries and lesser in service industries..
LEED i Sverige och i byggprojektet Borgarfjord 3.
This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..
