Vi lämnar spår på Internet : Integritet i relation till loggning på UpUnet
This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..
Ett svenskt kronvittnessystem? Att vara eller inte vara ett kronvittne
Kronvittnessystem har vid ett flertal tillfällen diskuterats i svensk politik som en möjlig åtgärd i arbetet mot organiserad brottslighet. Ett kronvittne är en person som vittnar om sin egen eller andras brottslighet och på grund av detta erhåller ett mildare straff för sina brott. Flera andra länder använder sig av kronvittnessystem på grund av de nyttor som finns med det, men forskning visar att det även finns problem med systemet. Syftet med denna studie är att besvara frågan vad kriminella personer har för uppfattning om att kronvittna i ett kronvittnessystem. Kvalitativa intervjuer genomfördes med före detta kriminella med erfarenhet av organiserad brottslighet.
Företagsstudie om värmeöverföring : Beskrivning av värmeflöden hos en lagerbyggnad
The study took place at a food corporation in Växjö, Sweden. It describes a building that contains four tanks in which glucose syrup is stored. The purpose of the study was to calculate the amount of heat that leaves the building and the amount of heat that is supplied by the installed heating equipment. Before the calculations could be implemented, all the systems that supply the building with heat had to be examined. With a small amount of information from earlier studies, the work to gather all the data necessary for the calculations began.
Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.

Sammanfogning av videosekvenser från flygburna kameror
The usage of Unmanned Aerial Vehicles (UAV) for several applications has in-creased during the past years. One of the possible applications are aerial imagecapturing for detection and surveillance purposes. In order to make the captur-ing process more efficient, multiple, cameraequipped UAV:s could fly in a for-mation and as a result cover a larger area. To be able to receive several imagesequences and stitch those together, resulting in a panoramavideo, a softwareapplication has been developed and tested for this purpose.All functionality are developed in the language C++ by using the software li-brary OpenCV. All implementations of different techniques and methods hasbeen done as generic as possible to be able to add functionality in the future.Common methods in computervision and object recognition such as SIFT, SURF and RANSAC have been tested..
Omslagstrender - en studie av vad som höjer uppmärksamhetsvärdet hos tidskrifter
Through interviews, a questionnaire survey and an indepth analysis of the Swedish magazines Veckorevyn and Magazine Café has a number of parameters been made visible. It was difficult to obtain an unambiguous result when the journal's target audience is crucial for the cover design. Nevertheless, we can generally say that the transparent varnish of covers, PMS colors and enclosing the journal in plastic do not increase the attention value, as this occurs in many magazines. Due to today's tough competition among journals, we believe that they will need to niche themselves much harder to survive. We also believe that the new, big trend is that more covers will become more plain and stylistically pure, with one big communicating image and fewer coverlines, as many covers were designed during the 1940s..
Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper
At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.
Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst
A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

This abstract describes the bachelor degree thesis in computer technology at Växjö University. The company BSR in Växjö has requested an application that can measure a cars performance, with attributes like acceleration times and engine power estimation. The communication between car and computer is via the USB port on the computer and the OBD-II socket on the car with the network protocol CAN, controller area network. Cars from VAG have been the primary focus group and the application has been tested on a Volkswagen Passat CC from 2009. The system is developed in the programming language C# in the environment Visual Studio with the framework .NET.
Från mästare till kommunalarbetare : En undersökning om trädgårdsmästaryrkets status- och kompetensförändring under perioden 1920-1955
This study of literature from the period 1920-1955 has shown that the profession of gardeners in Sweden went through several structural changes in the early and midst 20th century. The gardeners knowledge, which used to cover the whole horticultural spectra, was due to that no longer appreciated or useful. Prior the 1920?s the gardeners, especially the skilled craftsmen working for the upper-classes, were the ones who led progression in the horticultural field forward and their qualifications were many and diverse. Due to many factors, such as low economic and social status, functionalistic style and the fact that the branch were rationalized and modernized in general, lead up to a point where the gardener of old no longer fitted in, in the much more globalized and modern world of the 1950?s. .
Generationsskiften i familjejordbruk : genomförande och familjerelationer
Within the next five years about 15 % of the Swedish forest owners that will undergo a succession of ownership. Presently the most common way to acquire a forest estate in Sweden is to acquire it within the family. To decide to let go after a whole life as a forest owner and manager of your own land is for many people a hard decision to make and often requires a long process. The complex process that a succession of ownership often is includes both questions about economy, legal aspects and regulations, taxes and questions of more personal nature, often called soft issues. These personal aspects or soft issues are important and can if handled poorly or not at all negatively affect relationships in the family for a very long time.
Död ved i gallrad skog och nyckelbiotoper : en jämförelse av habitatkvaliteter för vedlevande lavar och mossor
A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. In old-growth forests most of the dead wood consists of logs and snags, whilst in managed forests a huge proportion of dead wood is made up of logging residues like stumps and FWD, fine woody debris (< 10 cm diameter). All these different types of dead wood may serve as substrates for epixylic bryophytes and lichens. However, few studies have been conducted on the relative importance of these different fractions of dead wood for the occurrence of bryophytes and lichens, especially when considering dead wood on thinned forest land.
Gravitationslinser
Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..
Spindeln mellan teknik och människa : En studie om hur interaktionsdesigner beskriver sitt yrke
In this bachelor thesis we have studied how interaction designers describe their profession. The research material is based on nine interviews with interaction designers. Questions cover areas such as interaction design tasks, what abilities they consider important, how they describe their relationship to the users, and cooperation with colleagues. We have analyzed the results using key terms such as habitus, field, and capital, as described by sociologist Pierre Bourdieu. The interviewees express humanistic views, and ask for more cooperation between interaction designers, as well as other people within the field of IT production.
