Vad händer när han slutar? : en studie om kunskapsbevarande i en organisation vid en nyckelpersons pensionering
Sammanfattning: Vi står inför en tid med stora pensionsavgångar, endast under 2011 kommer 124 000 svenskar att fylla 65 år. Då äldre anställda ofta innehar mycket kunskap efter lång erfarenhet inom en organisation finns en risk att kunskapen följer med dem när de slutar till följd av en pensionering. Med denna studie önskar vi kunna bidra med en större förståelse för betydelsen av en tydligt utarbetad pensionerings- och kunskapsledningsstrategi för en organisation då dessa stora pensionsavgångar väntar. Vi önskar även bidra med en ökad medvetenhet om kunskapsledningens relevans i organisationer, och att denna medvetenhet bör finnas hos alla anställda och inte endast vara individspecifik.Syftet med denna studie var att kartlägga och analysera det personliga nätverket runt en nyckelperson i en organisation för att kunna utvärdera nätverkets roll i bevarandet av kunskap vid nyckelpersonens pensionering samt identifiera kunskapsbevarande faktorer. Studien genomfördes som en kvalitativ fallstudie där både intervjuer och dagböcker användes för att samla in det empiriska materialet.
Slemhinneskadors inverkan på salivens innehåll av IgG och IgA
In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

Karakterisering av bioslam för modellering av biogasproduktion
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
Nätverkssäkerhet med IPS : Förbättrad nätverkssäkerhet med Intrusion Prevention Systems
Att skydda sin IT-miljö mot olika typer av intrång och attacker som till exempel trojaner,skadliga Java applets eller DoS attacker med hjälp av brandväggar och antivirusprogramär två viktiga lager i skalskyddet.I den här uppsatsen undersöks hur väl ett Intrusion Prevention System skulle kunna fungera som ett ytterligare lager i skalskyddet. Fokus ligger på hur väl IPS-systemet klarar av att avvärja attacker, hur mycket tid som går åt till konfigurering och drift för att få ett fungerande IPS samt hur prestandan i nätverket påverkas av implementationen. För att mäta hur väl IPS systemet klarar av att upptäcka och blockera attacker utförs två experiment där ett mindre nätverk attackeras på olika sätt. I det första experimentet skyddas infrastrukturen av en brandvägg och klienterna är utrustade med antivirusprogram. I det andra experimentet genomförs samma attacker igen fast med ett Snort IPS implementerat i nätverket.Resultatet av de genomförda experimenten visar att en IPS klarar att blockera ca 87% av attackerna, men nätverksprestandan påverkas negativt.
Säkerhet i Wireless Local Area Networks : En studie i säkerhetslösningar utförd på uppdrag av Saab Bofors Dynamics AB.
Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.
Analys av en metod för att extrahera generella regler från multipla nät
Rapporten som följer är en analys av en metod som genererar regler från neurala nätverk. Metoden heter VI-Analysis (Validity Interval Analysis) och är framtagen av Sebastian B. Thrun [Thrun]. VI-Analysis arbetar på det sättet att det neurala nätverket ses som en svart låda där endast de inputvärden och outputvärden som finns i nätverket används som underlag när regler ska genereras. Dessa inputvärden och outputvärden kommer sedan att få tillåtna intervall av VI-Analysis.
The Life and the death of commercail email : En studie av e-postens geografi med hjälp av Actor Network Theory
Denna studie belyser svårigheten för teknik och virtuell geografi att nå ut till mottagaren genom en kartläggning av e-postens geografi. För att skapa förståelse och fånga den osynliga processen bakom e-postens geografi utgår uppsatsen dels från teorin Actor Network Theory (ANT) och dels från intervjuer.Under studiens gång uppstod ny förståelse för e-postens komplexitet och ledde fram till en reviderad syn. I början av uppsatsarbetet betraktades e-posten enbart utifrån sin funktion som aktant och intermediarie men i takt med att undersökningen fortgick framkom att den samtidigt, utöver dessa funktioner, fungerar e-posten som ett heterogent nätverk med betydelsefulla komponenter såsom aktörer och aktanter. Enligt uppsatsens konklusioner är e-postens trajektoria beroende av den strategi som producenten använder under skapandet av elektroniska meddelanden. Ett kontinuerligt arbete mellan producent och konsument krävs för att e-postens trajektoria ska upprätthållas och leda fram till att det elektroniska meddelande som löper igenom det virtuella nätverket når sitt syfte..
En branschanalys av den svenska mobilmarknaden -Strategi, konkurrenssituationen och 4G:s påverkan
Background and problemThe Swedish mobile market is highly competitive despite the oligopoly that currently exists. A short product life cycle together with fads and new innovations puts pressure on the operators to respond to the ever changing environment and to develop and adapt their strategies after it.As a previous study regarding a specific operator?s strategy was cancelled due to the extensive confidentiality surrounding it, an interest was sparked to perform an industry analysis as this is clearly something the actors spend a great deal of time on developing. The launch of the 4G network will offer new opportunities for the operators regarding products services. It may also impact the competition on the overall market.PurposeThe purpose of this thesis is to present a deep analysis of the industry and give the reader a comprehensive picture of existing conditions.

Riskkapital : Roller, Involvering och Värdeskapande
In order to drive innovation and growth in a nation is it important to have innovative companies. Many of those innovative companies are smaller companies, which are in need of capital injections for expansion of its operations or to be able to produce a commercial product. In many cases the banks will not lend because they believe there is too great a risk that they will not get their money back. It is in this situation venture capital becomes interesting. Venture capitalists? see the potential the product and/or entrepreneur possesses and are therefore more willing to take the risk in investing in these companies.
Breaking the habitual : ett gestaltningsförslag för Hagebys nya aktivitetscentrum
Utifrån rapporter från bl.a. Riksidrottsförbundet (2007) går det att fastställa att aktivitetsytor som
planeras för barn och unga idag inte används jämlikt. Dagens planering tenderar att gynna killar i högre utsträckning än tjejer. Examensarbetet Breaking the Habitual ? Ett gestaltningsförslag för Hagebys nya aktivitetscentrum ställer sig kritiskt till detta och strävar efter att bryta denna planeringsstruktur.
Utformning av sidoområden med hänsyn till vägens livscykelkostnad
Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.
