Processbeskrivning av Rundvirkestransport : En Fallstudie hos Tra?frakt Go?taland AB

Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.

Revidering av dispensregeln från budplikt?

When anyone acquires control over a listed company the mandatory bid rule is triggered. This means that the person who acquires the control has to make an offer to buy the remaining shares in the company. The purpose of the rule is to protect the minority shareholders from the buyers. This rule has been considered to be burdensome and thus it is followed by an exemption rule which under some special circumstances may make the mandatory bid rule void. The purpose of this thesis is to analyze if the exemptions given by the Swedish securities council (in Swedish Aktiemarknadsnämnden) are in accordance with the purpose of the mandatory bid rule and if a review of these rules are needed.To answer the purpose, the Swedish securities councils statements has been analyzed, to determinate if the exemptions are in accordance with the purpose of the mandatory bid rule.

Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Den aggregativa demokratin : Hur Jürgen Habermas, John Dryzek och Stephen Elstub använder termen liberal demokrati

?Liberal Democracy? is a common term in political theory, and it is used as if it had a commonly accepted referent, with both normative and descriptive content. This is certainly the case in democratic theory, where it on the one hand seems to refer to a normative democratic model; on the other hand it is used descriptively, to refer to real-life democracies. The deliberative democratic sub-field is not an exception; on the contrary, the term is frequently used albeit rarely defined; yet the concept it refers to is supposedly developed enough to allow detailed propositions about its citizens?s political behaviour.This essay is an attempt to analyze how Liberal Democracy is used by three deliberative democrats (Jürgen Habermas, John Dryzek and Stephen Elstub), in order to understand the democratic model (or models), whether normative or descriptive, they refer to.

Markanvändning och ekosystemtjänster i en gradient från borealt till alpint landskap ? Vilhelmina Model Forest

Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.

Folkbibliotek och IT diskurser om folkbibliotek och informationsteknologi i fyra bibliotekstidskrifter

The aim of this Masters thesis is to examine public library and information technology IT discourses to see which relationships are established between them in four library journals. This is done in two steps, where first discourses are defined followed by an analysis of the relationships established between the public library and IT in each discourse. The questions from which the analysis emanates are as follows: What discourses exist around the public library and IT in the library journals? What conceptions of the tasks of the public library are constructed in the discourses? What conceptions of the tasks of IT are constructed in the discourses? What conceptions of the relationships between the public library and IT are constructed in the discourses? The theoretical and methodological starting-points are found in Ernesto Laclaus and Chantal Mouffes discourse theory. 37 articles from four library journals Biblioteksbladet, Bibliotek i Samhälle, DIK-forum and Ikoner - are analysed through a model in five phases.

Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

Projektmodell för mindre produktutvecklingsprojekt

How projects are managed can have a big impact on the project`s result. There are different types of frameworks on the market whose purpose is to help project leaders to pursue a successful project. Those frameworks focus on larger product development projects and both the literature and companies have addressed that the frameworks are too comprehensive for smaller product development projects. They have therefore asked for a framework that is more suitable for those smaller projects. To complete a project on time and to the planned cost is important in both larger and smaller product development projects.

Mätning av inköpsmognadsgrad: - en första ansats

This paper explores a model for self-assessment of purchasing maturity in large companies. The author adapts contemporary purchasing theory and further enhances existing tools and procedures to create a survey based instrument for maturity measurementThe paper also explores potential methodological challenges associated with conducting a more extensive study of purchasing maturity via the proposed model. A preliminary study is made and the learnings discussed.The preliminary findings of the survey indicate that the purchasing maturity varies with industry. The purchasing function average score was found to be 3,4 out of 6 with samples spread across the whole spectra ? agreeing with previous theories stating that the purchasing maturity is highly varied between different industries..

Varför läxor? : En studie om några mellanstadielärares tankar om och syfte med läxor

The aim of my study is to get an idea of how some teachers use homework, what they consider a good homework is, and what considerations they take to the students' home circumstances. I have made a qualitative interview study with four middle school teachers. The results of my study show that teachers can flip the classroom and use so-called preparatory tasks. The time saving aspect is a strong reason they choose that model. That students are able to practice their own responsibility and perform meaningful homework seems to also be in focus, but the biggest reason they use flipped classrooms seems to be because it is a more equivalent homework then traditional homework, and that students and their guardians also appreciate the flipped classroom model as they become more involved in their children's schoolwork..

FE-modellering av hjullast på sandwichpanel

This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.

Ammoniumåterkoppling på Himmerfjärdsverket ? utvärdering genom försök och simuleringar

Avloppsreningsverk står inför uppgiften att rena inkommande vatten för att möta lagstiftade gränsvärden till en så låg kostnad som möjligt. Att syresätta biologiska reningsprocesser är kostsamt eftersom luftningsanordningen förbrukar mycket energi. Ungefär en femtedel av Himmerfjärdsverkets totala elenergiförbrukning går till luftning av biologiska processer.För att öka Himmerfjärdsverkets energieffektivitet startades under 2010 experiment med olika strategier för luftflödesstyrning. En av verkets nitrifikationsbassänger byggdes då om för att möjliggöra zonvis reglering av syrehalten.Syftet med denna studie var att utvärdera reglering med ammoniumåterkoppling och syrehaltsprofil för styrning av Himmerfjärdsverkets nitrifikationsprocess. Utvärderingen baserades på reningsresultat och energiförbrukning.Med nuvarande reglerstrategi varieras luftningen genom återkoppling från syrehalten i den andra av sex zoner i varje luftad bassäng.

Folkbibliotek och TV-spelande ungdomar en studie i bibliotekariers attityder och värderingar när det gäller ett nytt medium på biblioteket

The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.
