Global Reporting Initiative : En komparativ studie om efterlevnaden av initiativets riktlinjer mellan Ericsson och Vattenfall

Title: Global Reporting Initiative - A comparative study on compliance with the initiative's guidelines between Ericsson and Vattenfall.Authors: Peter Leidhammar, Mattias ThorénSupervisor: Bo EnquistExaminer: Margareta BjurkloSeminar Date: 2009-01-14Background and problem formulation: The interest and the requirements that stakeholders have for companies sustainability issues are becoming increasingly important. Thus more companies are increasing their work on their sustainability reports. As there are no laws governing how these are to be designed, standards have been created by various organizations that companies voluntarily can follow. Now, after the Swedish government gave them the directive to follow the GRI's guidelines the Swedish public companies have started to follow this trend. The question then stand how much the private companies' sustainability reports differ from state companies and whether this can be traced to the differences in the companies' ownership and their stakeholders picture.Objective: The purpose of the paper is:· analyze how the GRI's guidelines are followed by the two organizations· highlight differences between them from a theoretical perspectiveLimitations: This paper is limited to two companies, one company owned by the government and one privately-owned company.

Utveckling av mobilapplikation

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.

Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

Balkanisering och klassifikation : En komparativ studie av klassifikationen av forna Jugoslavien, beträffande språk, geografi och historia, i DDC och SAB

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

Hur agilt bedrivs agil systemutveckling egentligen? En studie som undersöker hur renlärigt svenska IT-företag bedriver sina agila systemutvecklingsprojekt

Agile systems development has in recent years become very popular, and many companies today claims to be working agile. At the same time there are studies about agile system development that indicate that there are difficulties in fully adopting the agile way. The purpose of this qualitative study has been to examine how true Swedish IT-companies conduct their agile system development compared to agile theory, and we have specifically for the purpose of the study designed a framework that has been used as an analytical tool. The framework helped us to maintain a structured and objective approach when we examined the participating companies and their practices. The study showed that there were differences regarding how true to agile theory the different companies conducts their agile projects, and that the differences in part depends on how long the companies have been working agile.

Plusenergi och dess installationer : Kvarter Trettondagen

The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.

SkuldsaneringVägen tillbaka för överskuldsatta individer

The first Debt Relief Act was introduced in 1994 into Swedish law. The old Debt Relief Act was replaced on 1 January 2007 by the current Debt Relief Act. The current law is in many ways similar to the older law. The main change is the debt settlement process.The Debt settlement Act's main purpose is to financially rehabilitate over-indebted individuals. This aim should be balanced against the creditors' interest in getting paid for their claims.

Att testa kvalitet : En validerande informationsinsamlingsmetod för ökad kunskapsåterföring

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers.

Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

Energieffektivisering av stenstadshusen - genom byggnadstekniska energisparåtgärder

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
