Den estetiska kompetensen som bedömningsgrund : En jämförelse mellan privat och offentlig sektor

Since a few years back television has been on a verge of an enormous digital change. Web-TV is now growing at an incredible rate and is said to completely change the way we consume TV. The purpose of this essay is to determine and gain an understanding of how representatives of the broadcast industry looks at the phenomenon of web-TV and especially the different kinds of online video services and how they believe this will affect the television. Methods used are qualitative interviews which we compared with previous studies on the subject and acknowledged communication theories. The respondents were people with good insight and understanding of the media and TV industry.

Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab 

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

Påverkan på TED- spread under den nuvarande finansiella krisen

The purpose of this essay is to test for significance between TED- spread and four different macrovariables, housing prices, Federal funds rate, Asset Backes Securities and mortgage volume. Multiple regression has been used to search for significance between the dependent and the four independent variables. Our data consist of quarterly reports from January 1998 to June 2008. Our conclusion is that all of the four variables show a significant relation with TED- spread. The model explains 76 percent of the variation in TED- spread..

Effektiva lösningsmetoder för Schrödingerekvationen : En jämförelse

In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

Faktoranalys av EU: s strukturella indikatorer

This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.

Mobiltelefon utformad med EcoDesign

The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.

E-handel : Vilka faktorer styr konsumentens köp över Internet och då med fokus på hälsokostbranschen?

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

Utformning av kylkanaler och spånrum på superturbofräsar

This thesis describes how the chip space and coolant channels are designed in today?s mills, the ideas behind the design and what is considered to be the best method of cooling. It contains ideas on how the chip space can be simplified. It contains several concepts on how the cooling could be designed for better efficiency and manufacturability. There are also suggestions on how the cooling could be stopped when the cutter isn?t cutting.

Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

Logistisk tillämpning idag : en historisk återblick

In the rate of changes condition of the market in shape of increasing competitiveness situation, local as global, this leads to that logistics has to be developed in the same rate. Logistics has been developed from the military and after the war, logistics was figurative to the companies transport- and store problems. After this, logistics had been divided up into four different time phases (the seventies to the 21:th century). All these time phases have together develop the spectacle and focus of the logistics today. Afterward further developing of the logistics approach to Supply Chain Management (SCM) and afterward SCM, Demand Chain Management (DCM) was developed in aim to secure that the right products were manufactured on the basis of the end customers real requirement and wishes.This paper is taking the aim and problem formulation as a starting point.

Otillräcklighetens diagnoser : Kvinnors upplevelser av att leva med stressrelaterad ohälsa.

This essay discusses the problems with the high rate of long-term sickness leave among women in Sweden. It is based on interviews with six women suffering from stress-related illness. The results show that these women hardly ever recieved an explicit diagnosis and therefore did not feel that their illness was acknowledged. In the abscense of measurable symptoms they were sometimes stigmatisized and accused of simulating their problems. From this position they tried to legitimize their situation by presenting themselves as respectable women.

A work method for organizational development will be used in order to reach the findings presented in the thesis. First we study the strengths and weaknesses in today?s control system.

Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans

This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.

Software keystroke logging : Automatisering av skydd mot software keystroke logging

This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.
