KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER
The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.
Brandväggar för hemmakontor
Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.

As a municipal corporation, they seek consultation regarding internal as well as external review and investigation of the main structure of the network, its functionality and safety. By today?s increasing demands of Internet accessibility, availability of services and security far more extends the requirement of a complete network design. The foundation of networking rests on the balance between each of these necessities.
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.
Vetenskaplig kommunikation genom open access. Forskares attityder till open access-publicering inom odontologisk forskning
Open access has played a significant part in the development of scholarlycommunication. Today, several research funding agencies around the worldrequires that the results of the research it supports must be published openaccess where the underlying idea is that publicly funded research should befree and available to all users. The purpose of this thesis is to discuss the issueof open access publishing from the perspective of researchers in the field ofodontology, focused on their attitudes, behaviors and publishing experienceswith open access. Through a qualitative interview study with fiveodontological researchers, the results have been compared to previous studieson researchers' attitudes and experiences with open access. The results showthat both knowledge and experience with open access publishing is fairly lowamong the participating scientists.
Effekten av syskonplacering på Health Locus of Control : En studie om syskonplacering och kön kan relateras med locus of control ur ett hälsoperspektiv
Studier har visat att det finns ett samband mellan syskonplacering och locus of control, medan andra studier inte funnit något samband. Syftet med denna studie är att undersöka relationen mellan syskonplacering, kön och locus of control ur ett hälsoperspektiv hos gymnasieelever i årskurs 3. I undersökningen deltog 147 gymnasielever ifrån fem skolor i Kronobergs län. Resultatet visade att kön och syskonplacering samvarierade med intern health locus of control (F= 3,01;p< 0,03; ES= 6,2) och att syskonplacering och kön tillsammans inte visade någon signifikant inverkan på extern health locus of control (F= 2,20;p=<0,09; ES= 4,6). Fyndet kan indikera att manliga mellanbarn i större utsträckning strävar efter en intern health locus of control än kvinnliga mellanbarn.Nyckelord: Syskonplacering, health locus of control, intern- och extern locus of control, kön..
Jakten på en trygg oas i en torr öken : En studie om varför studententreprenörer väljer att delta i självorganiserade företagsnätverk
The aim of this study is to, by developing ideal types, describe why studententrepreneurs participate in self organised business network. The investigation is based on answers from 41 participants in the business network ?Företagare på Lnu?, as well astwo semi-focused groups, which where analysed by using Webers (1978) ideal types.The investigation shows that there are several reasons for student entrepreneurs to participate in self organised business network. For instance some people participate to gather knowledge from other student entrepreneurs for their own future, since they have an idea of soon starting their own business. Others participate just for the fun of knowing what?s going on at the university..
Strukturerat lärande genom Action Design Research. En studie om visualisering av behörigheter
As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.

Utvärdering av Artificiella Neurala Arkitekturer För Navigering
Den klassiska approachen till navigering innefattar att agenten håller en intern representativ modell av omgivningen. Denna approach har emellertid många nackdelar, speciellt för dynamiska miljöer. En modernare approach är att förlita sig på den faktiska omgivningen istället för en modell av denna. Detta arbete presenterar en undersökning av navigeringsproblemet och hur väl det löses av agenter vars kontrollmekanismer utgörs artificiella neurala nätverk. Tillförlitligheten hos de två neurala arkitekturerna Extended sequential cascaded network och Self-organized recurrent network bestäms genom experiment.
