Den svenska guldgruvan - befolkningsregistren : Teknikens betydelse för utveckling av forskningsinfrastrukturen kring de svenska befolkningsregistren
In this paper we examine the possibilities to develop the population based research in Sweden by using technological advancements. The problem that exists with population based research today is that there is a contrast between conducting important research on one side and preserving the individuals? integrity on the other. To examine this problem we are studying two projects that are active in this area. The two projects are SIMSAM (Swedish Initiative for research on Microdata in the Social and Medical Sciences) and DDB (Demografiska databasen).
Samband mellan laserdata och fÀltdata
To make it easier for forestry planning the forest owners needs data which describe characteristics of the forest. Such data you usually get from some type of inventory. A relatively new technology which probably is getting more important in the future, is laser scanning because of lower costs. But because the laser technology is relatively new you need to compare it with conventional inventory technologies to get better understanding of the possibilities the laser technology gives. This work intends to estimate field measured characteristics of the forest from laser data with help of regression analysis and then see which of the field measured properties that best could be estimated and which laser variables that gave the best results.
This study shows that heights has the best estimates, but biomass, diameter and volume also gives good estimates.

Möjligheter och begrÀnsningar i molnet
Idag vÀljer mÄnga företag och kommuner att placera data i molnet istÀllet för
pÄ en lokal server, detta medför nya problem som tidigare inte varit aktuella.
Datainspektionen har pÄpekat brister i hur tvÄ kommuner anvÀnder molntjÀnster
för att lagra personlig data dÄ de stÀller sig tveksamma till
molnleverantörernas hantering av data samt insynen till molnleverantörerena.
I detta arbete kommer det undersökas hur den svenska personuppgiftslagen
fungerar nÀr data lÀggs ut i en molntjÀnst. Resultatet av uppsatsen kommer Àven
visa pÄ de olika sÀkerhetshoten som finns i molnet och se vad sÀkerhetsexperter
sÀger för att ta reda pÄ om kommuner och företag Àr medvetna om och
uppmÀrksammar samma hot. För att ta reda pÄ detta har intervjuer genomförts med
en svensk molnleverantör, företag som utvecklar tjÀnster mot molnet,
privatpersoner som nyttjar molnet och experter inom sÀkerhet frÄn Blekinge
Tekniska Högskola, BTH.
Resultatet av studien visar att det Àr svÄrt att se om en amerikansk leverantör
uppfyller de svenska lagarna för personuppgifter, det visar ocksÄ att det Àr
teoretiskt möjligt att anlita en svensk leverantör och uppfylla lagen. Det har
Àven visat sig att den största oron gÀllande molnet Àr bristen pÄ kontroll av
data..
TillgÀnglighetsstrategi för kommunala planerare : Ett arbetssÀtt för att identifiera och planera ÄtgÀrder av enkelt avhjÀlpta hinder
There are many barriers and obstacles that need to be removed to make the urban environment more accessible for people with disabilities. There are currently no adequate tools for urban planners to assess and address these obstacles. Geographical Information Systems (GIS) provide powerful methods for the visualization and analysis of spatial data, including the kind of data important in studies of accessibility. This study suggests a method urban planners can use to identify accessibility obstacles and to propose future actions to fix them.A literature review was conducted to find out what has been done and what is new regarding the accessibility issues. Different methods were evaluated which in turn led to the construction of a multi-step analytical strategy.
Quantification of sleep in dairy cows in three different stages of lactation
The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

Diskkrypteringsprestanda i GNU/Linux
This thesis compares the impact on disk performance in a GNU/Linux environmentwith three encryption algorithms: AES, Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that is drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
Ăgandeskap av data i molnet - En studie om företags attityder och resonemang kring Ă€gandeskap nĂ€r de placerar sin data i molntjĂ€nster
Cloud computing has become a very publicized and popular concept in recent years, both in business literature and research, where data ownership is the security aspect which has usually been ranked the highest of the disadvantages that can be identified with cloud services. Today there is a lack of research on information ownership from an informatics perspective, as it is most often discussed from a legal perspective.In our study we interviewed six different companies that use cloud services, on which attitudes and reasoning they had on their information ownership. We compared these attitudes with the attitudes we identified in business literature and research on the subject. In business literature we found four recurring themes which were very clear about how a company should govern information ownership.Overall the results of our interviews showed that there is widespread ignorance at the companies on how information ownership in the cloud is regulated between the company and the cloud provider. All companies expressed that they had not experienced any change in ownership when they placed their data in the cloud, and they expressed no major concerns about how the ownership was handled.

Digitizing the Parthenon using 3D Scanning : Managing Huge Datasets
Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.
