Utveckling och tillämpning av modeller förkvantifiering av de ekonomiska konsekvensernaav ökad förbrukningsflexibilitet inom eldistribution
One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.
Går det att förbättra barns matematiska förståelse inför skolstart? : En studie om tidig matematisk stimulans av sexåriga barns förståelse för tallinjen 1-10.
Studie är baserad på Siegler & Ramani (2008) ?Playing linear numerical board games promotes low-income children´s numerical development?. Syfte är att undersöka om det med intensivträning (i form av ett linjärt tärningsspel) går att stimulera sexåriga barns talförståelse inom talområdet 1-10. Metoderna som valts är fältexperiment och observation. Fältexperimentet påvisar att intensivträning med ett tärningsspel, utfört under 4 stycken 15 minuters lektioner under en tvåveckors period, tydligt kan förbättra barns talförståelse medan observationen visar att utfallet påverkas av pedagogens olika yrkesverktyg samt undervisningens organisation (en-till-en undervisning).

Arbetet är ett utredningsarbete som går ut på att försöka lokalisera felkällor och göra förbättringar på en testutrustning som mäter rodervinklar på akterdelen på en robot. Rapporten innehåller en översiktlig bild över den tidigare metoden och dess felkällor som hittas vid test av den tidigare metoden. Utredningen utmanar också många utav antagandena som är gjorda för beräkningarna av den tidigare metoden. Detta utförs för att kunna bekräfta eller dementera antagandena. Detta görs i form av matematiska modeller som testar olika delar av metoden.
Reglering av matarsystem vid höghastighetskapning
Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
Kvinnor som ledare inom industriföretag : En studie om hur kvinnor kan ta sig tillledande positioner
Research question: How does the industrial company Scania work to get more women in leadership positions?Purpose: The purpose of this work is to describe how companies in a male-dominated industry can work to get a higher share of female leaders.Method: This survey was based on a deductive approach with a qualitative method. Theories have been obtained primarily from scientific articles and the empirical part has been collected through interviews from the companies Wiminvest and Scania.Conclusion: The conclusions the study came up with was different elements that companies in male-dominated industries can work with to get a higher share of female leaders. The first thing that companies can do is to join the project BON or similar projects to work on this issue. They can work with workshops and lectures to disseminate knowledge about the topic.
Kronunionens återkomst : En empirisk underso?kning av konjunkturscykler, arbetskraftsro?rlighet och handelsintegration fo?r att avgo?ra mo?jligheten att info?ra en gemensam valuta i Norden
This paper is an assessment of whether the Nordic countries constitute an optimum currency area (OCA) or not. Hodrick Prescott-?filtered data of real Gross Domestic Product (GDP) and rate of employment are used to investigate the similarity of business cycles between the target countries through a series of correlation analysis with Sweden as the base reference country and also by using a linear regression model. Additionally there is an evaluation of trade volume and labour mobility between the countries. Our results indicate that Iceland had the least similar business cycles within the Nordic countries and that the area should therefore possibly comprise Denmark, Finland, Norway and Sweden. .
Introduktion av buskskikt i ungskogar
Young stands in urban forests often lack a shrub layer, though shrubs play an important structural and biological role in forests. All layers interact with one another to form a multilayered stand, in which shrubs have a vital role.In this diploma thesis, theoretical models for forest dynamics are compared with four reference stands to detect factors, and principals for introduction of shrubs in young stands. In these stands four different ways of introduction were found. In one trees and shrubs were planted together at the same time. Shrubs spontaneous spread under a canopy of mature forest, in another.
Resurshantering av personer i multiprojektmiljöer
An important task for project managers in multi-project environments is to effectively choose the right people to the project team. For organizations, it means being able to prioritize and plan human resources among the various projects running in parallel. The purpose of this paper is to describe how a project manager in multi-project environments looks at the allocation of people in their projects. We did our research through literature reviews and interviews with seven project managers.The research shows that the studied organizations highlight both the expertise and the personal factors in an election. They do not use any specific personality test to identify their staff.
Att infiltrera, dissekera och korrigera betvingade sinnen : En argumentationsstudie av skriftliga publikationer från Jehovas vittnen
The purpose of this Master?s Degree is to identify and understand different techniques of argumentation in written texts originating from the religious movement Jehovah's Witnesses. The purpose is also to contribute with a theoretical and methodological framework for other scholars. The focal point of the thesis is sexuality and how the authors of the texts try to convince the members to follow the movements' doctrines in this regard. I use a modified version of the well-established grounded theory method.

The competition gets fiercer with each player andthe outcome for the linear TV channels has to be to change in some way. This is aqualitative interview study with producers at Sweden?s leading children channel?Barnkanalen?, how they experience the adoption to this new media landscape.
Liv i den övergivna trädgården? : Tro och sekularisering i Sverige, speglad mot dominerande teorier om sekulariseringsprocesser
This master thesis summarizes contemporary theories on secularization processes in the Western world, and compares these with the example of Sweden, which by many scholars is considered to be the most secularized country in the Western world.I do this by dividing the most influential theorists in five different groups. In each group I explain how the theorists formulate and motivate their positions. These groups are:1) The secularization paradigm, where secularization always accompanies modernization. (Therorists: Steve Bruce and Peter Berger (in the 1960s)2) The paradigm basically accepted, but revised to depend on existential security, rather than modernisation as such. (Pippa Norris and Ronald Inglehart)3) Religion returned in the public sphere.
Normering av en objektiv metod för att mäta käkrörelser med 3D-videoanalys vid tuggning samt en jämförelse mellan käkens rörelseomfång vid tuggning och tuggeffektivitet hos unga vuxna
This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

Analysis of Intent Specification and SystemUpgrade Traceability
The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.
Magnetiska egenskaper hos Öje-Diabasen, Dalecarlia
A study of paleomagnetic remanence and anisotropy of magnetic
susceptibility (AMS) has been performed on the Öje-Diabase
in Dalarna, Sweden, and on basic dikes associated with the
alkaliquartzsyenite/granite Noran-pluton in central Sweden.
Based on isolation of directions of characteristic magnetization
in the basic rocks, a division into three different groups (A,B,C)
has been made. Group Aconsists of dolerites of Jotnian origin,
both dolerites from the Öje-Diabase and dikes associated with
the Noran-pluton are included in this group, making them coeval.
Group B is suspected to show a re-magnetization from the later part
of the Svekonorwegian orogeny. Group C belongs to the
Blekinge-Dalarna-Dolerites (BDD). Thermal demagnetization of
dolerites revealed two different types of demagnetization behaviours,
one where magnetite clearly was the source of the remanence, and an
other with a linear decrease in magnetization intensity. The measurements
of magnetic anisotropy reveals a magnetic fabric with an almost
horizontal foliation and a lineation that indicates a fairly uniform NNW/
S-SE flow direction of the magma..
