Sveriges informationsutbytesavtal med Monaco och Liechtenstein : Leder avtalen till ökad insyn och effektivt informationsutbyte?
This thesis concerns agreements for the exchange of information relating to tax matters between Sweden and the previous tax havens Monaco and Liechtenstein. Monaco does not apply any tax on income or capital for individuals and Liechtenstein has strict bank secrecy, both aspects are supposed to be counteracted by similar agreements. The purpose is to investigate whether the entered agreements increases transparency and effective exchange of information in accordance with the OECD´s objectives in the area. Furthermore, is there any regulation in the agreements that can be seen as potentially loopholes to avoid the exchange of information and if so; may these loopholes be justified in any way?OECD believe that the tax havens favorable tax regulation is resulting in harmful tax competition and they identify lack of transparency and lack of effective exchange of information as the main reasons.
Portföljoptimering med courtageavgifter
Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.
Vem köper KlimatEl och varför? : Kvantitativ undersökning av Kalmar Energis elhandelskunder
Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

Title: What´s the problem? - A study of revenue recognition in IT-consultant companiesProblem: How do the chosen IT-consultant companies recognize their revenues? What difficulties do the interviewed companies experience in connection with the revenue recognition?Purpose: The purpose of this empirical study is to study how companies in the IT-consultant industry recognize revenues, and to investigate if the companies perceive any difficulties in connection with the revenue recognition. The aim of the study is to give useful advice and guidelines to companies in the IT-consultant business based on the extracted result. Method: The survey took place in Vasteras and started with a preliminary interview with a certified accountant, who had great knowledge of the subject revenue recognition. Then seven companies from the IT-consultant industry were selected, whereof two took part in semi constructed interviews. Study of the other five companies? ways to recognize revenue was made through their annual reports. Conclusion: One of the studied companies recognizes their revenues according to the rules in IAS 18, which is because it is listed on the stock exchange.
Mätning av stamdiameter med markstående scanner :
Booth for operational planning of harvesting and for long term planning, data is today collected manually. Intensive objective field inventories are usually too expensive. To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. The objective of this study was to validate how a terrestrial laser scanner could be used to measure stem diameter, and to test how the errors depend on distance from the scanner and tree species.
Two plots (one pine and one spruce) were used for this study.
Ska det framtida Göteborg växa och gro?: En diskursanalys gällande beslutsfattares syn på urbant jordbruk
An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.
Prognos för offentlig sektor: Molnigt, med chans för IT som en tjänst
The public sector in Sweden outsources its core business to a very large extent, whileinsisting on running its IT operations internally in a traditional way. IT as a service ingeneral and cloud computing in particular has become incredibly popular in recentyears, offering cost efficiency and greater ability for the business to concentrate on itscore activities, which is why it should be a promising alternative to the traditional wayof running IT internally. To achieve an understanding of why IT as a service has yetto take off in the public sector, a study of its use of IT/IS, what the effect of IT as aservice is, and the opportunities and challenges that cloud computing represents, isnecessary.The study, which was conducted using a qualitative hermeneutic approach, was initiatedby a literature review, followed by six in-depth interviews with five respondents,all of which hold many years of experience in the area. The outcome of the interviewsindicated that IT as a service should represent a promising and feasible way of reachinghigher levels of cost control, and a greater focus on core activities. Furthermore,the results indicated that Swedish legislation along with a high level of businesscomplexitymight be reasons for the low amount of IT as a service in the public sector.Through careful analysis and examination of the business? current situation, as well ascomprehensive knowledge of Swedish legislation with regards to the implications ofLagen om offentlig upphandling, the public sector can avoid IT as a service becomingmore expensive and more complicated than necessary, and achieve cost efficiencyalong with a greater focus on its core activities through it.Future research could examine the possibility of a framework for the integration ofcloud services within the public sector?s IT/IS environment, and whether there is aspecific size of a cloud implementation at which it?s more cost efficient to go withtraditional IT operations..
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.
Borrning och gängning av laxkilar till vågkraftverk med industrirobot
To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.
Aktiv- och Indexförvaltning : - Kan svenska investerare få högre riskjusterad avkastning genom aktiv förvaltning?
Nearly 74 percent of the Swedish population invests in funds and the options are therefore various. The Swedish private investors can choose between active and passively managed funds. Fund managers, who seek to generate higher returns than the market, manage active managed funds. Unlike the active managed funds, passively managed funds do not require any active investment decisions.Fama?s (1970) efficient market theory reflects all available information in the stock price, therefore it is not possible to predict how the stock price changes.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.
Effektivisering av kylsystem på Utö värdshus
Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.
Byggnadslogistiskt arbete för minskat slöseri ? En studie över arbetsfördelningen vid innerväggsmontage på Tuve Bygg AB:s projekt Stapelbädden etapp 3
The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.
En jämförelse av Sveriges och Storbritanniens producentansvar för förpackningar :
The purpose of the thesis is to compare Sweden's and Great Britain's total costs for their systems regulating producer responsibility for waste packages. Producer resonsibility is a strategy implying that producers are responsible for their waste also after its use. Sweden and Great Britain introduced different systems systems after an EU directive was adopted in 1994 (94/62/EC), and they have resulted in entirely different recycling levels in the two countries.
In the Swedish system, responsibility has been delegated to the industry who are responsible for reaching the determined goals. The economic instrument used is a fee, set and managed by the industry. The British system is more centrilised, and the economic instrument used to finance recycling of waste is a system based on transferable permits.
The thesis compares the four different alternatives: delegated and centralised methods, and fees and transferable permits analytically.
