In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

En fallstudie tillämpades för att undersöka de inbyggda apparna, Internet Explorer 10, den nya utforskaren File Explorer och reparationsverktyget ?Återställ datorn utan att ta bort filer? i Windows 8. Analysen visade att apparna E-post, Kontakter och Meddelanden sparade större delar av användarens Facebook-profil lokalt på datorns hårddisk. När bildfiler öppnades upp med appen Foton sparades miniatyrbilder av originalet på hårddisken. När videofiler spelades upp med appen Video sparades filnamnet i filer.

Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

The measuring of logs is important in the sawmills process to the sawn products. The technology of automatic wood measurement is continuance developing. This study has the purpose to see how the different techniques and the routines works of measure frames for determining of wood value and sorting in sawmills. The study is performed as a literature study and a survey. The survey includes some of the Swedish sawmills that produce more than 10 000 cubic meters sawed products per year.

Several studies has identified the locker room experience as a potential deterrent for participation in physical education. Both psychological and physical issues arise due to several factors. Psychological issues include different kinds of verbal and physical violations, comparisons between pupils, feeling of vulnerability along with a stressful schedule. The physical environment can contribute to negative experience for pupils in terms of filthy premises and cold showers. These factors may contribute to higher absentee rates in physical education.

Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation.  In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

Syftet med studien var att undersöka svenska hamnars möjlighet att investera i land­strömsteknik och sedan betala tillbaka investeringen genom försäljning av elektricitet till ankommande fartyg. Studien är en systematisk litteraturöversikt baserad på en sys­tematisk litteratursökning som sedan presenteras i en teoretisk fallstudie. Litteraturöversikten utgår från fem studier som beskriver kostnader gällande utbyggnad av landströmsteknik. Första delen av resultatet består av beräkningar för vad investeringskostnaderna för utbyggnad av landströmsteknik till en enstaka kaj kan uppskattas till. Därefter beräk­nades kostnader för att generera en viss mängd elektricitet ombord och jämfördes med kostnaden för att köpa den från marknätet. Sedermera beräknades en vinstmarginal om elektriciteten säljs för samma pris som den kostat om den genererats ombord i dieselgenerator.

This is the project of making a stage design for Batboy ? the musical, a cooporation with a network of musical artists. The aim of the project was to create a space on stage that strengthens and expands the experience of the story told, and find design solutions that give an extra dimension to the story. The prerequisites for my work were partly defined from the produc¬tion, as were my limitations. In the cast of ten artists some were to play more than one role, often one of the opposite sex.

Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.

A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy.

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

 The purpose with my study was primarily to illuminate the students' expectations on gained knowledge during their studies at the upper secondary school Hotel- and Restaurant program, and to what extent these expectations were fulfilled. Secondarily, the purpose was to compare the students' expected and perceived knowledge with the program goals set by the Swedish government and the knowledge requirements expressed in a pilot study made by the Education council of the Hotel and restaurant business (UHR, 2007).I chose a quantative approach and I used an anonymous group enquiry among students at the Hotel- and Restaurant program at two different upper secondary schools to carry out my study.Tendencies in the result suggested that the students at the Hotel- and Restaurant program expected high knowledge level within the competence areas of Guest reception and communication, Cleaning and hygiene, Cooking of cold and hot dishes and Waiting. The expectations were not big within the areas Computers and Internet and Business economics and management.Fulfillment of expected knowledge tended to be high within the areas where the expectations were big. It might therefore be a good investment for schools to work on the student expectations to increase motivation within the low expectation areas.A confrontation of the tendencies in the result with the program goals and the competence requirements expressed in the UHR study, suggested that the upper secondary Hotel- and Restaurant education might focus some more the areas of Guest reception and communication, Beverages and Organization of banquets. Business economics and management should be given much more weight..
