Marknadsanpassning : hot eller möjlighet?

Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.

Vad bestämmer fonders prestation och avgift? : En studie på svenska aktivt förvaltade aktiefonder under perioden 2005-2014

This study analyzes 66 Swedish actively managed mutual funds investing in the Swedish stock market during the period 2005-2014. The purpose is through pooled data regressions analyze the relationship between both the mutual fund?s annual fee and risk-adjusted return to the fund?s characteristics. The characteristics of the study are the size of the fund's assets, age, if the fund is bank managed or not, Tracking Error, and standard deviation of return.By using the performance measures of CAPM, Fama and French 3-factor model, and Carhart?s 4-factor model monthly risk-adjusted returns are created for all funds over the period.

Digital 3d landskapsmodellering : detaljeringsgradens betydelse för läsbarheten hos digitala tredimensionella landskapsmodeller

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

Doing Business in China - A Best-practice Model for Foreign Invested Small and Medium-sized Enterprises (SMEs)

Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.

?Antingen f?r man sitta ensam och vara nykter och drogfri, och det ?r ju ingen som orkar det ?ver tid. Eller s? f?r vi skapa sammanhang d?r man kan g?ra p? ett annat s?tt? - En kvalitativ intervjustudie om socialsekreterares erfarenheter av sociala n?tver

This study examines the opinions of social workers regarding the social networks of people with a substance addiction. The intention was to get a more nuanced understanding of what characterizes a positive or negative social network, as well as which functions different types of social networks serve. Data were collected through qualitative interviews with seven social workers. More specifically the social workers were oriented towards working for social services with clients that struggle with substance abuse. The empirical material has been analyzed with a thematic analysis.

Parametriserad 3D-modell av cyklon : Parametrisering av en 3D-modell av ett cyklonfilter i SolidWorks för snabb framtagning av nya konstruktioner till Outotec Skellefteå

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

Matrismodellen vs Two-part regressionsmodeller - effekter på Region Skånes resursfördelning

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Afghanistans demokratiseringsprocess : En kvalitativ fallstudie om förutsättningarna för att lyckas med konsociationell demokrati i ett av världens fattigaste länder.

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Funktionshinder barriär eller genväg till biblioteket? En fallstudie om rörelsehindrades och synskadades biblioteksanvändning

The aim of this Masters thesis is to, from a users perspective, investigate which factors affect the library use for six persons with disabilities or visual handicaps. My method has been a case study and the methods applied are interviews and observation. As a theoretical framework I use Tom Wilsons theories and models about information behaviour and transform them to a model about library use. Answers are sought to the following questions: - What does the library use look like for six persons with disabilities or visually handicaps? - How do they experience the library in their own municipality? - Which factors affect the disabled persons library use and experience of the library? All interviewees showed a very positive attitude towards the library and the majority of them visited the library regularly or received audio books by mail.

Realoptioners förklaringsvärde och praktiska tillämpbarhet: En tillämpning på den svenska onlinespelmarknaden

Real options analysis is a method for assigning value to flexibility in decisions, coming from uncertainty in future outcomes. This thesis ascertains to what degree this method is superior to traditional net present value analysis, with regards to ease of implementation in relation to the benefits from being able to measure the total value. Real options analysis is evaluated with a case study of the Swedish online gambling market, and conducted with the binomial framework of Copeland and Antikarov (2003). The authors find the sensible use of real options dependant on the specific situation to which it is applied, i.e. a certain degree of future uncertainty and managerial flexibility is necessary for justification of the increased workload.
