Vilka faktorer påverkar börsbolagens nedskrivningsbeslut?
By using univariate analysis, tobit and logit regressions, this thesis investigates determinants of asset writedowns. After controlling for variables indicating reductions in asset values, the results show that changes in senior management are significant in explaining the writedown decision and magnitude, which is in line with previous research. The explanatory power of changes in senior management has not increased with the transition to IFRS in 2005. No evidence is found supporting the hypothesis that the explanatory power of management incentives is higher for more discretionary types of asset writedowns..
Uttorkning av Betong
This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.
Förbättrad resistansmätning för grova aluminiumledare
The goal with this master thesis has been to evaluate and to examine the
stationary resistance bridge. The resistance bridge uses a 4-point measuring to
determinate the resistance, which is used in the manufacturing of the
conductor. It is then used when the resistance is to be decided for coarser
aluminium conductors. A conductor has to fulfil certain demands to be able to
move forward in the process. One of these demands is the resistance in ohm/km,
which has demands that the measure values of the resistance bridge are as true
and precise as possible.
The stationary resistance bridge had been examined through various kinds of
measurements to be able to see how stable the system is and how to obtain a
measure value as optimized as possible.
Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer
This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

Syfte och frågeställning: Syftet med denna studie är att undersöka de eventuella fördelar styrketräning med yttre belastning kan ge kvinnliga truppgymnaster på juniornivå. Frågeställningar: Vilken effekt på explosivitet i nedre extremitet har sex veckors powerträning med yttre belastning på truppgymnaster? Skiljer resultaten sig från de som uppnås vid traditionell gymnastisk styrketräning?Metod: Två lag som representerar Sverige-eliten på damsidan i juniorklassen delades in i test- (n=7) och kontrollgrupp (n=8). Testgruppen genomförde under sex veckor ett specialdesignat träningsprogram riktat mot power medan kontrollgruppen genomförde traditionell gymnastisk styrketräning. För- och eftertester genomfördes för att utvärdera effekterna av programmen.
Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.
Kvalitet-i-Bruk för Beslutstödssystem inom Thoraxkirurgi
The aims of the practical work carried out for this thesis were to redesign a clinical decision support system for thoracic surgeons, called AssistMe, and to evaluate the concept behind this system. The main objective of the thesis is to give an account of the considerations that were found to be of key importance for designing a clinical decision support system for thoracic surgery. Another aim was to let future users test the system after it had been redesigned and evaluate the concept behind it. The thesis also investigates users? experience of the system and their views on whether it would be applicable in their daily work practice.
Brukarinflytande - en oklar självklarhet : om brukarinflytande i särskilt boende inom äldreomsorgens kommunala verksamhet
This paper is a qualitative study on the influence of the residents in a special communitydwelling within the care system for elderly. The purpose of the study is to describe and analyse with a user perspective how particularly staff members but also a group of retired people living in this dwelling interpret and articulate the concept of resident influence. How the retirees can influence the design and the content of the activities and the organization. How today the residents influence is carried out with the ideas and visions of the future.My methods include qualitative structured, semi-structured and non-structured interviews within a general frame of a resident questionnaire. The staff members present the current situation and reflect on the reasons for obstacles for resident influence.The group of retired people who lives in structures originating in the Swedish long-term care system and homes for the elderly tends to adjust to given routines and express a low-voiced wish for increased influence.
Klassifikationssystem på webben: Traditionella och nya
The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
Medvind eller motvind? : granskning av fem tillståndsansökningar från vindkraftprojektering i Sverige
The Swedish Government has decided that Wind power should have a higher contribution to the electricity generation in Sweden. Their goal is that, by 2015, the yearly production by Wind power should generate 10 TWh. In year of 2006, the 760 wind mills in Sweden generated only 0,936 TWh. Despite good wind conditions in a large extend of Sweden's land- and coast areas, the slow rate of new wind mills establishments will likely result in unattainable goals.
The major problem for new establishments of wind mills is the extensive and complicated permission process. An expert group of environmental studies (Expertgruppen för miljöstudier) was commissioned by the Government to make a report concerning the problems with the expansion of wind power in Sweden.
Från ord till (e-)handling : - Integration av e-handelssystemi SiteVision
The client, Senselogic, had noticed an increased demand for an e-commerce system integrated into its product, SiteVision, something that did not previously exist. Senselogic wanted to integrate a third-party system to manage e-commerce. The problem was that there were very many e-commerce solutions to choose from. In order to select the best system it was necessary to evaluate the e-commerce systems and compare them to each other. To identify the elements that has to be included in an e-commerce system a study of literature was conducted.
Identitet i den somaliska diasporan : en intersektionell studie av kvinnors jag och delaktighet i samhället
This work applies intersectionality to five Somali women self-narratives and focuses on their identities and positions in Swedish society, but also their relation to Somali society. Since people constructs in relation to the environment, this work studies the impact of environmental confirmations of their own self. Intersectionality is brought into the social work with an operational attempt, and shows how critics of power and interplay between theories and empirics can provide new knowledge. Intersectionality also demands some alterations of the social constructionists? idea of the ego.
Utveckling av internordersystem för SharePoint
SharePoint is a web based platform designed to provide internal communications and file sharing for businesses and organizations.In this project, we created a system consisting of multiple applications to be used together with SharePoint. These applications are meant to simplify the workflow for internal orders of products. The system is targeted towards companies that do not have a flexible approach to digital orders or companies that want to integrate this functionality into their SharePoint platform. The project includes, in addition to the creation of the system, installation of the software and the servers needed to run a SharePoint environment and their configurations.The system consists of four applications where one of these, the store application, is required for the system to be used at all. The other applications are an order management application, a purchase application and an incoming delivery application. Of these four, we have implemented the store application and the order management application. Our hope is that users will find the system easy to use and graphically appealing..
Vad krävs av en ERP-leverantör för att i framtiden tillfredställa mindre företag?
Ett ERP-system syftar till att ta hand om företagets resurser och skapa ett enhetligt integrerat system för dessa. ERP-system kan också användas för informationsutbyte mellan företaget, kunden och leverantörens system. Behov av ERP-system finns inom de flesta branscher oavsett storlek och inriktning men kritik har riktats mot att systemen inte lever upp till användarnas förväntningar eller tillfredställer användarens behov. Arbetets fokus ligger koncentrerat på hur mindre företags uppfattning om ERP-system är och vad som krävs av en ERP-leverantör för att i framtiden tillfredställa mindre företag. En surveyundersökning har använts för att få fram relevant information för att lösa min problemprecisering.
