This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.

Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.

Our aim with this study has been to show the central factors that we consider have had animpact on public libraries in the "information society". We have studied two communities in the south of Sweden, Ronneby and Sölvesborg. These two communities have both started a development to the IT society, a society where information plays a great role, where the technique is the tool that supplies information.Ronneby community had early the aim to be the chief Swedish information center. A priority on information technology has therefore been obvious for them. Sölvesborg community has had another method and time schedule towards the IT society.We have been studying the documentation of aim and the strategy for IT development in different levels.

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.

Entrepreneurship as playing a important role for economic growth has been discussed by a number of theorists such as Joseph Schumpeter and Israel M. Kirzner. William J. Baumol developed these theories as he considered that all entrepreneurship doesn?t lead to economic growth, some entrepreneurial activities may even lead to stagnation.

Vi har i samarbete med HemoCue AB utfört ett exemensarbete inom konstruktionsteknik.  HemoCue AB utvecklar, tillverkar och marknadsför patientnära medicinteknisk utrustning. De erbjuder testning av patienter på ?plats? med samma  noggrannhet och precision som om testet skulle ske på ett laboratorium med ett laboratorium instrument. Syftet med detta projekt var att ta fram en laddstation till ett mätinstrument.De krav som vi hade att följa var många, de mest utslagsgivande var dock att laddstationen skall vara placerad liggandes på bordet och att användning av instrumentet under laddnings tiden skall vara möjlig utan några som helst problem.De metoder som vi valt att arbeta efter är dels Brainstorming och dels Fredy Olssons metoder för Princip- och primär konstruktion(1976). Vi har även tittat en del på Arne Åkessons tillverkningskonstruktion(1981). Att vi valt att arbeta med dessa är för att få med all viktig dokumentation, från idé till färdigt konstruktions underlag.Detta examensarbete har resulterat i en prototyp av en laddstation som uppfyller samtliga krav och önskemål som vi haft att arbeta efter.  Det underlag som vi tagit fram kommer HemoCue AB troligtvis att utveckla ännu lite längre innan laddstationen kommer att i bruk..

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.

In the faster growing pace of changes and competition in the global economy, factors promoting group effectiveness are of interest. How do components of leadershipstyle, especially transformational, team climate and selfefficacy correlate? To answer this question 3 questionnaires regarding leadershipstyle (MLQ), team climate (TCI-Short) and selfefficacy (self developed) were distributed to employees of a Swedish installation company (108 participants). Moderate positive correlations were found between climate and selfefficacy and between varying elements of leadership and selfefficacy. The leadership behaviour Contingent Reward correlated moderately with all climate dimensions and strongly with selfefficay.
