Innovativa Metoder f?r Brandgasventilation : En Studie av Tillufts?ppning i Takniv?

Denna studie unders?ker en alternativ utformning av termisk brandgasventilation. Utformningen bygger p? att ers?tta tillufts?ppningar i markplan med r?kgasluckor i tak med hj?lp av brandteknisk installation i form av r?kgardin. Syftet med arbetet har varit att g?ra en j?mf?relse mellan denna hypotetiska utformning och traditionell brandgasventilation f?r att kunna utv?rdera om samma effekt kan uppn?s med de olika metoderna.

Heuristisk detektering av trojaner

The heuristic methods used by the anti-trojan application TrojanHunter have been evaluated. The evaluation shows that the heuristic scan engine of TrojanHunter has a very good detection ratio and that the detection ratio can be even further improved by implementing the suggested improvements, the most important of which is a white list to avoid misidentifying files that are known not to be trojans..

Aktiv ventilstyrning

To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

Elektronstrukturbaserad magnetiseringsdynamik

In this project a method used for performing accurate simulations on magnetization dynamics based on constrained field density functional theory has been validated and used for performing computations on a few magnetic materials. The method has been shown to simulate systems consisting of iron well, but there are still problems with simulations of alloys containing both magnetic and non-magnetic materials..

Funktionsnedsatta personers förutsättningar på arbetsmarknaden : En studie om exkluderande och inkluderande processer och faktorer

This qualitative study investigates the conditions on the labour market for disabled people by examining which factors and processes contribute to disabled peoples inclusion to, or exclusion from the open labour market. Stigmatisation is also used as an analytical tool to better understand the exclusion of disabled people from the open labour market. The material to this study is drawn from qualitative interviews with the employees of the Swedish Employment Agency which specialises in supporting disabled people to find employment.  In conclusion, disabled people face several barriers which makes them more susceptible to become excluded from the open labour market. Such excluding barriers include a demand for high efficiency and productivity from employers, bigger cooperation?s and public organisations unwillingness to employ disabled people and prejudices from employers, especially against people with psychiatric disabilities. The employees of the Swedish Employment Agency suggest that they would be able to work more efficiently to help disabled people find employment if they had to do less administrative work, and would be able to work with fewer clients per employee.

The dynamics behind Consistency: Case study on NTT Group and Deutsche Telecom

The main aim of this thesis is to investigate the implications and dynamics behind consistency between individual resource allocation decisions and corporate strategy concept. The telecom industry, a high-velocity environment going through an extensive deregulation process, is put under the magnifying glass. Japanese telecom giant NTT Group is compared to its German counterpart Deutsche Telekom. Potential antecedent factors in the strategic decision-making process to consistency are studied. It is also examined whether there is a direct interplay between consistency and economic performance.

Den yngre generationens delaktighet i det lokala utvecklingsarbetet : En fallstudie av dialogprocessen i utvecklingsarbetet "Skellefteå 2030"

The ambition to involve younger people in future planning processes in order to get full participation of all groups in the society requires a deep and well-planned dialogue. Although, participation not always means inclusion. The purpose of this study was to analyze how the younger generation in the society is included in the future work. This is based on a case study of the developmental work in the municipality of Skellefteå.Questions that were answered were how the municipality has made the participation possible? To what extent has the younger generation been involved? How did this group experience their participation? The methodology consisted of mixed methods that include observations, surveys to the session leaders and to the participants in the dialogue and three interviews with two participants and one municipal civil servant.The result showed that the open information didn´t reach the younger generation to the open dialogues although the dialogue design gave good conditions for participation.

Fjärrvärmesystem

This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

Integritet och långsiktig användbarhet hos textdokument : En avvägningsproblematik vid digitalt bevarande

This thesis is about a potential trade-off between integrity and long-term usability in the choice of file formats for preservation of text documents. Five common formats are discussed: plain text, PDF/A, Office Open XML Document, Open Document Text, and Markdown. The formats are compared with respect to four criteria related to integrity and usability and to the records continuum model: support by widely used software, stability, rendering of contents and reusability.It is concluded that no single format is optimal with respect to all four criteria, when it comes to preserving typical documents in a modern environment, with more or less complex formatting and document structure. Therefore, the feasiblity of using two or more formats for preservation of a single document (e.g. PDF/A combined with Markdown and/or Office Open XML) is discussed.

Vi sitter tillsammans : Upplevelser av samhörighet och ledarskap i ett traditionellt kontorslandskap.

The office is the working environment in which an increasing proportion of the population spends their days . One type of office are open plan offices which are characterized by several people sitting together in the same room without spatial boundaries . The general discourse of this kind of offices is that they constitute an advantageous design that allows organizational changes without the need for redevelopment . From a work perspective, this office design is both criticized and acclaimed . Problems with noise is frequently reported in research which can lead to ill health.

Distribuerad öppenhet : En studie av konceptualiseringen av öppenhet inom open access-rörelsen

The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.

Öppen MjukvaruMigration : En studie om för- och nackdelar med en migration till öppen mjukvara

Denna uppsats behandlar en undersökning som gjordes efter det att en gymnasieskola i Örebro migrerat från Microsoft Office till Open Office. I studien undersöktes vilka för och nackdelar som lärare upplevde efter migrationen samt vilka problem som uppstod då öppen mjukvara används i en miljö som är dominerad av proprietär mjukvara.Det tillvägagångssätt vi valt är en metodtriangulering där vi samlat in data med hjälp av tre olika insamlingsmetoder, en litteraturstudie, kvalitativa intervjuer och en kvantitativ enkät. Dessa insamlingsmetoder utformades så att litteraturstudien var av bredare karaktär och leder till att intervjuerna blir av mer specifik karaktär som i sin tur ger oss kvantitativa frågor till enkäten.Det vi funnit under arbetets gång är att migrationen lett till interoperabilitetsproblem med existerande proprietära system och även att filer tolkats olika av de båda kontorspaketen. Lärarna såg större skillnader mellan de båda kontorspaketen är vad skolan och kommunen förutsett och tyckte att de mer avancerade funktionerna är svårare att använda i Open Office vi har även sett en efterfrågan utbildning..

Öppna problem i läroböcker för kurs Matematik A

The purpose of this essay is to investigate the presences of open-ended problems in the textbooks of high school Mathematics A. For practical reasons the study was limited to three textbooks and two topics, Fractions and Area & Volume. The Essay also describes the theory behind open-ended problems and why they should be used. I identify three criteria as a definition for open-ended problems. The study found that only 7,6% of the investigated tasks qualified, and met at least 1 criterion.

Konstruktion, mätresultat och simulering av deltavinge

Avdelningen för strömningslära vid Luleå Tekniska Universitet har en vindtunnel som främst används till utbildning i aerodynamik för studenter. I skrivandets stund finns bara en vinge (osvept) som tillåter att 3? dimensionella effekter kan studeras och jämföras med en vinge som har 2? dimensionell strömning av samma sorts vingprofil. Resterande vingar har bara 2?dimensionella egenskaper eftersom deras spann sträcker sig från vägg till vägg i vindtunnelns testsektion.

Undersökning av genuttrycket av homeoboxen HOX A6 vid pyometra samt försök att bygga upp en in vitro-modell för pyometra

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.
