Ipv6 : En empirisk studie i hur Ipv6 protokollet har utvecklats de senaste åren.
Internet grows, so it?s cracking, soon will all IPv4 addresses be allocated and a solution is urgently needed. The new protocol, IPv6 is the solution to this problem. With a size of 128 bits against IPv4s 32 bits gives IPv6 a huge amount of addresses to distribute. The security addition that may be added manually in IPv4 is the standard with the new protocol.
Faunapassager : How animals cross roads
A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.
Situationen för anhöriga till yngre personer med demenssjukdom
Syftet med föreliggande studie var att undersöka hur bra vi är på att bedöma ålder på omaskerade och maskerade ansikten. Syftet var även att undersöka om det fanns systematiska fel som är förknippade med åldersbedömning av maskerade ansikten.Totalt fick 60 försöksdeltagare, samtliga ungdomar, skatta åldern på 60 fotografier av 30 maskerade och 30 omaskerade män. Fotografierna var indelade i två åldersgrupper, yngre och äldre, och samtliga stimulipersoner förekom i både den maskerade och den omaskerade varianten.Resultaten visade att försöksdeltagarna var bättre på att skatta åldern på omaskerade ansikten än på maskerade. Inga skillnader i systematiska fel fans mellan maskerade och omaskerade ansikten.Bilder av unga ansikten skattades med högre precision än bilder av äldre ansikten..
Kommunikationen i miljökonsekvensbeskrivningsprocessen : en intervjustudie om infrastrukturprojekt
Communication during the process of Environmental Impact Assessment:
Interviews concerning three infrastructure projects
Environmental Impact Assessment (EIA) is a method to describe the possible impact of a planned project. The aim of such an assessment is to aid a sustainable development, by supplying a comprehensive basis for decision-making. Today there are many people working with EIA in different forms, representing both different interests within the community, as well as having different individual points of view. The proponent is responsible for the EIA, but it is of interest to study the relationship between the different participants who are involved in this process. The aim of this report is to study how the different disciplines involved have communicated with each other and amongst themselves, what characterises good communication, and if anything should be improved.
Nätverkens betydelse för turistdestinationen : en studie av gotländska turistrelaterade nätverk
The tourism industry is growing and with its growth competition between destinations rises. In competition, cooperation and collaboration between tourism operators seem beneficial when creating an attractive and dynamic tourist destination.The purpose of this study is to describe and discuss the significance and influence of tourist related networks at a tourist destination, and therefore this study aims to examine the question: What significance do the tourist related networks have at a tourist destination?This study focuses on seven networks on Gotland that are tourism related, and the representatives of the networks were interviewed in order to get their view on the network and its significance to the destination. The study shows that networks have an important role in creating a unified tourist product of the destination, and in reaching out to the potential visitors through joint destination marketing. The study also shows that the tourism related networks helps to improve the reception of the tourist at a destination and to secure the quality of the tourist destination and its tourist products..

"I den mörkaste stunden kommer ljuset." : En analys av hjältemyten i två postapokalyptiska romaner.
The purpose of this study is to explore specific pedagogical activities that benefit the student's verbal language development and to learn more about how our schools use teaching methods to achieve the ambitions in the governing documents in Sweden. The aim is finding the correlation between theory, research, governing documents and the educational work in our schools. This study contains an empirical survey in intention to see how teachers, pupils and school administrators experience school activities, to see if those activities are formed with the intention for pupils to reach the learning goals according to the governing documents.The aim of this study has been achieved by relating empirical data with theories and previous research on conversation analysis. Goffman's and Norrby's research on the importance of dialogue and previous research on dialogicity studied by Dysthe, Vygotsky and Bakhtin are presented. Those are related to empirical data and show that most teachers realize the importance of integrating dialogues in daily activities and in different learning contexts.
Demokrati och diskurs. En normativ analys av diskursiv påverkan på de demokratiska värdena öppenhet, ansvarsutkrävande och inflytande
The idea that I put forward in this thesis concerns the democratic system and the threat from discoursive impact on its core values. I focus my normative analysis on three of these democratic values: transparency, accountability and influence ? and what democratic problems the discoursive impact causes in conflict with them. I have used a critical discourse theory to define discourse and discoursive impact, by focusing on the process of discourse, rather than its nature. I deal with the political structure where I claim that the essential relation between citizen and politician is disrupted, due to lack of information and the imminent problems of the existing network society.
Migration av Excelbaserat system till webbsystem : Implementation av ett planeringsverktyg inom telekom
Syftet med examensarbetet är att redogöra för hur ett system baserat påExcel kan migreras till en webb- och databasplattform. Initiativtagare tillarbetet är en avdelning vid Ericsson AB i Linköping. Avdelningen använderExcel till datalagring och presentation av testmiljöbeskrivningar ochönskade migrera detta Excelbaserade system till ett webbaserat dito. Någraav de problem som uppkommer vid migration är: nya säkerhetsrisker; hurdata ska ordnas i databasen för att uppnå sökbarhet och versionshanteringsamt hur presentation av data ska styras.För att svara på dessa frågor har vi utfört en förstudie och enimplementation av systemet Node Network Plan Database (NNP DB),vilket ämnar ersätta det Excelbaserade systemet. Rapporten beskriver hur:säkerhetsrisker har minimerats genom att införa lämpliga skydd; databasenhar designats för att uppnå sökbarhet och versionshantering; presentation avdata kan styras.NNP DB visar sig vara effektivare, ur ett tidsperspektiv, än detExcelbaserade systemet.
A foreign aid dilemma : a study of budget support versus project aid
Foreign aid is a very debated and controversial topic. The most recent studies have focused more on GDP growth and foreign aid correlation, however not much of the debate has focused on what kind of foreign aid should be given. The most common foreign aid is budget support, often a bilateral funds transfer between two countries. This kind of foreign aid can be both conditional and unconditional from the donors? perspective.
Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Identifiering av lakbara potentiellt farliga ämnen i gummiasfalt
The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.
Jämförelse mellan neurala nätverk baserad AI och state-of-the-art AI i racing spel
Denna rapport jämför prestandan mellan state-of-the-art AI-botar i racing
spelet TORCS och en AI-bot
som kör med hjälp av ett artificiellt neuralt nätverk (ANN-bot). ANN-boten, som
implementerades som
en del av arbetet, använder en feedforward arkitektur och backpropagation för
inlärning. Ett separat
program som användes för att träna det neurala nätverket med träningdata som
spelats in från TORCS
implementerades också. Som state-of-the-art AI-botar användes AI-botar som har
använts i en tävling.
De fyra AI-botarna testades på åtta olika banor och data om hur lång tid varje
varv tog och hur snabbt
AI-botarna körde sparades och sammanställdes. Resultaten visar att på banorna
som ANN-boten klarar
av att köra runt så är ANN-boten snabbare än en den långsamaste
state-of-the-art boten, men ANNboten
klara inte av majoriteten av banorna som den testades på.
Sanning med modifikation : En kvalitativ studie om Polisens förtroendearbete på Facebook
The purpose of our study is to see how an organization, and also a administrative authority, communicates by using social media. The organization in this case is the Swedish Police, because of their paradoxical problem with confidentiality versus openness and transparency. The Police has over a hundred Facebook-accounts, where they try to have a open dialogue with their publics without breaking the law of secrecy. Our general purpose of the study is also to see what the pros and cons are of having a own media channel, instead of the traditional media and their often anticipation twists.The result of the study showed that the three different police precincts, which we investigated in our essay, are working in three different ways. The gap may affect their overall reputation and trust gained by their publics.
