Forensisk hårddiskkloning och undersökning av hårddiskskrivskydd
Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd bedöms ha tillräckligt pålitliga skyddsprinciper, vilket motiveras av dess oberoende från både hårdvara och operativsystem. Vidare undersöks hårdvaruskrivskyddet Image MASSter(TM) Drive Lock från Intelligent Computer Solutions (ICS). Några egentliga slutsatser gick inte dra av kretskonstruktionen, bortsett från att den är uppbyggd kring en FPGA (Xilinx Spartan-II, XC2S15) med tillhörande PROM (XC17S15APC).
Robust internetinfrastruktur med DNSSEC och IPv6 : En studie av DNSSEC- och IPv6-implementationen hos utvalda organisationer i Sverige
Domännamnssystemet DNS är en vital och ofrånkomlig del av internet. Det är dock sårbart för attacker. DNSSEC är ett sätt att minska sårbarheten hos DNS. I detta examensarbete har data om ett antal domäner samlats in med hjälp av Zonemaster och domain information groper för att sedan bearbetas med hjälp av bash-skript och java-kod. Detta data har sedan analyserats.

Frivillig revision - Vad avgör rekommendationen? : En studie ur revisorns perspektiv
Aim The aim of the thesis is to explain the factors that affect the auditor's recommendation concerning audit services to customers who are not subject to mandatory auditing.Background and problem In 2010 mandatory auditing for small companies was abolished. It is common for the auditor to provide recommendations re-garding whether or not a customer should chose to retain the audit. The question is which factors can explain the auditor's recommendation.Method and empirics This thesis uses a deductive approach with inductive elements and a combination of qualitative and quantitative data is used. The qualitative data consists of a pilot study and the quantitative data consists of a questionnaire survey. The analysis of the empirical data was performed using regression analysis.Theory This thesis applies an eclectic approach where the starting point is legitimacy, institutional theory, professional theory and decision making theory to develop a model.Results and conclusions The notion of the recommendation as well as the extent of the recommendations can be explained by factors related to the auditor's agency affiliation and the auditor's personal qualities..

Magkänsla mot matematik : Kan mekanisk rekrytering förhindra diskriminering?
The aim of this study was to investigate if a mechanical recruitment process could be a useful tool for employers to avoid discrimination. National and international law protect jobseekers from discrimination during the recruiting process. Despite this individuals frequently report that they are treated unfairly when they apply for a job. In line with this research shows that some individuals do not have the same opportunities in the labour market as the rest of the population. This study focus on discrimination based on ethnicity, age, gender or disability.Today most of the hiring decisions are based on employers professional judgement.
Kulturanvändande bland Unga : En studie om kulturvanor, ungdomars livsvillkor och bibliotekets roll
The aim of this bachelor thesis has been to examine and develop our own understanding about how young people in Sweden (16-29 years of age), take part in cultural activities. As librarians it is important to know what kind of activities and interests this particular group has. With Pierre Bourdieu?s theoretical framework towards habitus and capital we are interested to see if there is a connection between one?s cultural use and background, if different access to capital with or within groups has an affect or not. With both statistics and interviews with people within our target, we believe this data has been sufficient enough to conduct a good and valid study.
Evaluation of Xilinx System Generator
This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.
Russinen ur kakan: - uppföljning av kampanjer i byggvaruhandeln
The Swedish do-it-yourself (DIY) market has expanded in recent years and is today a SEK90 billion market. Competition is fierce, however, and the DIY retail chains compete over market share with extensive marketing campaigns. Advances in computer technology have made it possible to acquire and compile huge quantities of point of sale data. However, due to a lack of economic theories and statistical methods, this data cannot be effectively utilized and the effects of the campaigns are not measured in any detail. In this study a new method was used to examine the effects of marketing campaigns in the DIY consumer market.
Utvärdering av prototypen för ett kollaboratorium inom biblioteks- och informationsvetenskap
This study is a formative evaluation of a prototypecollaboratory for sharing data collection instruments inlibrary and information science (LIS). The aims were to findout: how the study participants, five hospital librarians,experienced the interaction with the prototype while workingwith predetermined tasks; and their views on the differentfunctions of the prototype collaboratory.Methods used for data collection was as a survey; followedby a think-aloud session where the participant verbalisedhis/her thoughts during the interaction with the prototype;and finally a semistructured interview. The survey wasanalysed with a frequency distribution, while the data fromthe other methods were analysed qualitatively by extractingthemes from the transcribed sessions.The results show that although the librarians expresseddifferent problems while working with the interface, mainlyrelated to the language in the prototype collaboratory anddifficulties with the page for applying metadata, all of themwere confident in being able to learn the system after using itfor a while. The librarians had a positive attitude towardssharing data collection instruments as well as comments inthe prototype collaboratory. At the same time, they wereaware that students and researchers might have differentabilities or incentives to work and share information.
Diskussioner inommatematikämnet : Kreativa och Imitativa diskussioneroch när de används i undervisningen
The purpose of this essay is to examine when teachers choose to discuss mathematics withstudents rather then just talk about mathematics. A definition where used to distinguish betweenan interaction that is not a discussion and an interaction that is a discussion. This definition hasbeen created by drawing ideas from other works into making a quite simple definition whichtherefore is easy to observe. The discussions are also separated into two different kinds ofdiscussions. The first and most common category of discussion are one where only imitativereasoning is used.
Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder
This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.
Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning
To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.
Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning
Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.
Bootstrap som hjälpmedel att öka noggrannheten och bedöma precisionen vid probitregression, med tillämpning på hörselmätningar
In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.
