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.
Uterummet i undervisningen : en lÀromedelsanalys inom biologi
This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver.

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.
Big Data inom den svenska sjukvÄrden : En studie om framtida hinder och möjligheter
Denna studie har genomförts med syftet att redogöra för vilka möjligheter och hinder som kan uppstÄ vid införandet av Big Data-baserade IT-lösningar inom den svenska hÀlso- och sjukvÄrden. Studien bygger pÄ en explorativ fallstudie med fokus pÄ det svenska projektet 3R- Framtidens vÄrdinformation. Intervjuer har genomförts med personer som Àr insatta och kunniga i Àmnet och dÀrför kunnat bidra med en sammanfattad bild av vilka initiativ och ambitioner som finns i dagslÀget. Studiens resultat visar att Big Data kan bidra med en mÀngd möjligheter till förbÀttrad sjukvÄrd i Sverige. Resultatet visar pÄ att möjligheten med att samla all information i en gemensam kÀrna, bidrar till bland annat förbÀttrad forskning, en förbÀttrad relation mellan vÄrdgivare och patienter, möjlighet att kunna utföra prediktiva analyser samt underlÀttar arbetet med diagnostisering av sjukdomar.
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.

The case in this study was VÀxjö municipality. Three procured nursing homes for elderly were chosen in the municipality as examples of implementation and use of evaluation. The method for retrieving empirical data and the analyzing of it was based on triangulation.
Psykisk h?lsa och oh?lsa i f?rskolans sociala l?rmilj?. En fenomenologisk studie om pedagogers erfarenheter.
Flera forskare lyfte att f?rskolan har stora m?jligheter att arbeta f?rebyggande och
h?lsofr?mjande med barns psykiska h?lsa. Trots detta visade Folkh?lsomyndigheten i
?rsrapporter att den psykiska oh?lsan g?r l?gre ner i ?ldrarna och att k?tiderna till barn- och
ungdomspsykiatrin v?xt. Det framkom att det fanns en kunskapslucka kring barns psykiska
h?lsa och oh?lsa inom f?rskolans kontext och forskare ans?g att barn befinner sig i milj?er och
grupper som inte alltid ?r sj?lvvalda.
Target Capital Structure and Adjustment Speed- a dynamic panel data analysis of Swedish firms
The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.
R?relse i fritidshem. En empirisk studie genom intervjuer med l?rare i fritidshem.
Fysisk aktivitet ?r viktig. Uppsatsen bildades d? vi ville unders?ka hur fritidshemmen arbetar
med fysisk aktivitet och m?rkte att det finns v?ldigt lite forskning om fysisk aktivitet p?
fritidshem. Syftet med studien var att f? kunskap om l?rarna i fritidshemmets arbetss?tt och
till hj?lp har vi anv?nt tre fr?gor;
? Vad ?r l?rare i fritidshemmets uppfattningar av riktlinjer om elevers fysiska aktivitet
enligt l?roplanen?
? Hur arbetar l?rarna i fritidshemmet f?r att bidra till att ?ka elevers fysiska aktivitet i
fritidshem?
? Vilka f?ruts?ttningar det finns f?r elevers fysiska aktivitet p? fritidshemmet enligt
l?rarna i fritidshemmet?
Genom enskilda semistrukturerade intervjuer med ?tta legitimerade l?rare i fritidshem
samlade vi in material d?r vi unders?kte deras f?rst?else av Lgr22s riktlinjer, deras strategier
f?r elevers fysiska aktivitet samt f?ruts?ttningar de har f?r fysisk aktivitet.
Teorin vi utgick fr?n var det salutogena perspektivet, begreppet r?relsegl?dje, begreppet
KASAM samt barndomssociologiska perspektivet.
