Green IS ? a Systematic Literature Review

This thesis provides a systematic literature review of a selection among current papers andarticles on Green Information Systems (IS). The main focus is on the current state of Green ISin academic research. This study aims at gaining a deeper understanding and a clearer view ofthe state-of-the-art of IS for environmental sustainability research, with the goal of clarifyingthe diffuse idea of what Green IT/IS is, and what differentiates Green IS from Green IT.To support the objective of this study, the articles selected for data analysis were collected byusing a systematic literature review as research and analytical method. Within the thesis, adescriptive angle with an interpretative character is used to analyse the data extracted.A theoretical framework based on concepts from sustainability, Green IS and Green IT isemployed in order to analyse and compare terminologies and frameworks used in the studiedarticles. Furthermore, the different dimensions of sustainability and the various terms used todescribe Green IS are analysed comparatively.The result and analysis are discussed in a conclusion confirming the on-going ambiguity ofthe terms Green IT and Green IS and the transformative power of IS.

En undersökning av framtidametoder för att säkra förband i produktion

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Sista inlägget ? varför sluta blogga? : En studie av bloggare som avslutat sina bloggar

 By changing focus from the active blogger to the ex-blogger this study focuses on a part of the blogosphere that is generally overlooked, why bloggers stop blogging. 30 terminated blogs where studied and the ex-bloggers where contacted. Six main reasons why a blog is terminated was found: Changed life situation, The blog effecting private life, The blog effecting the professional life, Done with testing to blog, Blogging about an event, Done with the blog ? the logical termination. Outside the main focus of the study  it was also evident that most bloggers terminate a blog to put focus of one of their other blogs or start a new one.

EmoWheel : En metodutveckling för utvärdering av emotionellt engagemang

This is a study of how emotional engagement can be measured and be taken into account in the development of websites. We believe that emotions become relevant only when viewed in correlation to how users experiencing a webpage. In this study, we developed a tool for use together with user tests where the information about the user's emotional engagement can add new value to the evaluation. The tool allows the user to mark, on the website, his/her emotions and level of engagement represented by colored circles, generating quantiative data on how users feel about the website. The tool is part of a method for evaluating the emotional engagement that we have developed which consists of user testing supported by the tool and accompanied by interviews..

Förslag på riskklassificeringsmodell av ekologiskt kontrollerade aktörer : En jämförelse med andra länders ekologiska kontroll

In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.

Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

Proportionalitetsprincipen : En studie av dess inverkan i LOU

The principle of proportionality is considered one of the most important contemporary legal principles on which it intends to protect individual citizens against disproportionate action by the authorities. This aroused our interest prior to this study. The essay reveals how such behavior might look like and how courts have chosen to adjudicate in cases where the individual has been discriminated against or subjected to unreasonable demands in public procurement. That section of the law that were current throughout all court cases are Public Procurement Act (2007:1097) LOU. That which we have seen in every court case is that the applicant has not received a proper fair chance when the requirements of the contract often been asked in a way that either exclude the smaller applicant company or rule out various potential applicants parties due to excessive and sometimes unnecessary requirements.

Testing and optimization of Unicorn Fluid-Structure Interaction solver for simulating an industrial problem

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

Standardisering av bakpanel.

HAFA Bathroom Group has given us the assignment to develop a standardized back panel for their bathroom cabinets. This cabinet is going to be applied to most of their current and future cabinet solutions. To this point, they have constructed unique suspensions-and back panels for most of their cabinet models. They have also been forced to pull wiring and assemble the cabinets differently because of factors like; position of the wall sockets, dimensions of the cabinets and their shapes.The company wants to distance themselves from their current solution, firstly because the cost of having manpower to design each individual suspension solution, secondly because they will save a lot of money when the manufacturing process requires a minimum of components to be constructed. As a result of this, the company can use their resources better to develop future products.The main idea is that the consumer isn?t required to change the suspension or back panel when they decide to buy a new cabinet.

Rättssäkerhet inom skatteprocessen

In todays society the legal rights of the individual are a highly debated subject. Among other things there have been a debate going on in Dagens industri where the participants have discussed the National Tax Board, courts of law and law and order. The legal rights of the individual have been described as threatened and uncertain due to deficiencies in the tax assessment.There are difficulties defining the concept of law and order due to the fact that there is no generally acknowledged explanation. The concept of law and order originates from the citizens ability to predict the consequences of their actions provided that the authorities actions are regulated according to current legislation and will therefore protect the citizens from possible abuse of power that can exist within a state governed by the law.The purpose of this paper is to analyse law and order within the tax assessment through a method that experiments with real and imagined situations with the main purpose of interpreting current legislation. The paper collects essential legislation, preparatory work together with established practice and supplements the method with information from articles, dissertations and the National Tax Authority?s documented directions within the tax assessment.Through juridical argumentation concerning areas, such as legal rights essential to the citizens and the tax assessment, the paper results in aspects essential to the individual involved in tax dispute.

Motpol eller legitimeringskälla? - en studie av användningen av hållbarhetsbegreppet inom Malmö Stads fysiska planering

Sustainable development and sustainability is nowadays expected to be integratedin modern city planning and permeate the entire planning process. At the sametime, sustainable development has an inherent vagueness, leading to a greatdiversity of interpretations of the meaning of this concept. In this thesis strongsustainability and ecological modernization are used as two different interpretationsof sustainable development. Using these two interpretations, an analysis of thecurrent use of the concept of sustainability within the city planning of Malmö isperformed. The analysis shows that the interpretation of sustainable development inthe city of Malmö can be deduced to ecological modernization and thatsustainability is looked upon as one way to improve the attractiveness of the city.Investments to increase ecological and social sustainability must be legitimized asleading to a potential increase in economical sustainability (growth) and the focusof increasing the sustainability in the city has shifted from ecological aspects toeconomical aspects.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

Termisk hantering av litium-jon- batterier i elektriska drivsystem

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

BLOD, SKATT OCH JORDEB?CKER. En j?mf?rande fallstudie om informationskapacitet i det postkoloniala Latinamerika

Tax revenue is crucial in order for states to survive. States vary a lot in terms of tax revenue however, and different explanations are frequently debated among political scientists. Recently, scholars have argued that the variations in tax revenue among European states today can largely be explained by their ability to collect information about the citizens and their belongings during the early modern period (1450-1800). States that were early in acquiring this information in so called cadasters, could use it in order to collect tax. This fiscal capacity thereafter sustained in a path dependent manner.
