Arkeologihund : En studie i experimentell arkeologi om möjligheten att använda hund som arkeologisk prospekteringsmetod för att lokalisera humanosteologiskt material.
In today?s archaeology there?s a growing need for non-invasive prospection methods. However there?s a methodological gap and what?s missing is a method for locating human bones. In this study a specially trained German shepherd is put through scientific tests determining how good the dog is at telling the different between the scent of human and animal bones.
Identifiering av infektion i sår, en litteraturstudie
Regardless of what discipline nurses work in, wound care is one of the tasks. Caring for wounds involves early detection of signs of infection, in order to avoid complication. Wound infection extends suffering for the patient and causes unnecessary costs for society. The aim was to describe how nurses can identify infection in wounds. Method: The design of the study was a literature review, where13 scientific articles were examined and analyzed.
Dagens Agora : En kritisk granskning av Internets möjligheter och begränsningar
The time we live in now is significant for its many ways of spreading information- it is indeed the era of communication. The Internet is the main reason for this evolution, where you can reach out to any corner in the world in less then a second. Information is flowing over us and we get more and more used to being in a constant accessible state. The individual might spread his own word as he wishes. From a democratic point of view this should give a great opening for everyone into the public spheer.

Övervakningssystem för inomhusmiljöer
Övervakningssystem har haft en viktig roll i samhället under en lång period. Syftet med dessa
systemen har inte ändrats, det är alltid säkerhetsaspekten som har varit huvudpunkten.
Effektiviteten på ett övervakningssystem beror oftast på den mänskliga faktorn, någon måste
bearbeta bildflödet som spelas in för att dra definitiva slutsatser. Under senare år har dessa
övervakningssystem, i takt med teknologins utveckling, blivit mer intelligenta. Metoder som
tillämpar automatisk analysering av en given bild har introducerats, vissa av dessa tekniker
har redan hunnit bli en standard. Denna studie ska utveckla en prototyp som använder sig av
tekniken och stresstesta för att identifiera eventuella brister.
IT-relaterade hot - professionella IT-tjänstemäns farhågor och möjligheter
The objective of this thesis was firstly to examine the possibilities of creating a universal tool for evaluating IT-security. When all the material was gathered we saw that we had strayed away from our subject and that our focus was on IT-threats and IT-professionals apprehensions and possibilities on the subject. The purpose of this thesis was there after to find and identify threats and counter measures in publications and later discuss these with IT-professionals. We found and identified several threats that the professionals encountered in their work. These threats ranged from techniques used by hackers to threats that can arise when the users on the network are poorly educated.
Kökets bråkstakar : elevers förståelse för bråktal i hem- och konsumentkunskap
The aim of this study has been to investigate students? understanding of fractions when they occur in the practical subject home economics. In order to investigate this, the learning study method was used. Learning study can be understood as a method to gain deeper understanding of what is learnt by students during a lesson to increase learning outcome.The variation theory framework has been utilized to analyze the results of this study. The object of learning was chosen to be addition of fractions bigger than one half when they appear in home economics.
FPGA-design av en STDM-baserad multiplexer för seriell multiprotokollskommunikation
The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.
Kloridhalter i gran utmed en depositionsgradient för havssalter :
The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.
Automatisk detektering av diken i LiDAR-data
Den här rapporten har utrett möjligheten att automatiskt identifiera diken frånflygburet insamlat LiDAR-data. Den metod för identifiering som har valts harförst skapat en höjdbild från LiDAR-data. Därefter har den tagit fram kandidatertill diken genom att vektorisera resultatet från en linjedetektering. Egenskaper-na för dikeskandidaterna har sedan beräknats genom en analys av höjdprofilerför varje enskild kandidat, där höjdprofilerna skapats utifrån ursprungliga data.Genom att filtrera kandidaterna efter deras egenskaper kan dikeskartor med an-vändarspecificerade mått på diken presenteras i ett vektorformat som underlättarvidare användning. Rapporten beskriver hur algoritmen har implementerats ochpresenterar också exempel på resultat.
Etnicitet och kön : Påverkar grupptillhörighet bedömningar av korrekthet i centrala meningar från ett vittnesmål?
Syftet med denna studie var att studera möjligheten att bedöma korrekthet i vittnens utsagor beroende av deltagarnas grupptillhörighet. I studien ingick 120 deltagare som antingen fick se en film med vittnesmål från fyra vittnen med enstaka centrala meningar eller läsa en text med samma meningar. De viktigaste mätningarna i denna studie gjordes efter signal detection theory (SDT). Resultaten visade att deltagarna inte skattade mycket över slumpnivå och ofta till och med under slumpnivå i sina bedömningar. I en hopslagning av betingelserna (text/film) visade analyserna att män generellt var signifikant sämre än kvinnorna på att bedöma vittnesmål, men att kvinnorna gör fler falska alarm än männen i bedömningen av textversionen. De funna könsskillnaderna i hur vittnesmål bedöms diskuterades..
Biogaspotentialen av matavfall sorterat ur hushållsavfall.
To achieve the Government's milestones for 2018, which means that 50 % of food waste shall be separated from household waste and undergo biological treatment (composting or anaerobic digestion). Hultsfred, Högsby and Vimmerby are three adjacent municipalities of Kalmar, county Småland. During 2012 and 2013 analyzes were performed on their household waste to determine its composition. The household waste is currently collected in one fraction. The work, examines how much food waste the household waste contains. From the amount of food waste, the biogas potential is examined - how much food waste biogas generates and how much energy it corresponds to. Food waste is broken down by microorganisms under anaerobic conditions (anaerobic digestion) in a biogas plant.
Åtskildheten : En lacansk läsning av Birgitta Trotzigs roman Sjukdomen
While almost 23 percent of the students in the Swedish upper secondary school are foreigners, only a fraction of the school libraries? collections consists of literature written in other languages than Swedish or English. This study examines how five school librarians experience the task of working with literature composed in foreign languages in the multicultural and multilingual school of today. The results of the qualitative interviews are analyzed in relation to the legislation and policy documents that the school libraries are working by, and also in relation to the theoretical framework of sociocultural theory and the theories on second language acquisition developed by linguist Jim Cummins.The study shows that while multilingualism is discussed as an important matter in the legislation and policy documents that the school libraries work by, the librarians in this study largely view the question of foreign literature as peripheral. Most part of the librarians connects first language reading to leisure-time activities rather than curricular activities, and stresses that the Swedish language should be prioritized in Swedish schools.
Från kvinnans problem till problemfri kvinna : En undersökning av audiovisuell reklam för sanitetsprodukter till menstruerande kvinnor mellan åren 1970 och 2000
This thesis tries trough qualitative analyzes to illuminate advertising and its didactic aspects, how menstruation and menstruating women are portrayed over time. The method underlying the survey is didactic, diachronic comparative and hermeneutic. There will also be a feminist point of view on the material. The issue is about how the advertisement presents sanitary products and menstruation and how a menstruating woman is portrayed.The conclusion is that the image of a menstruating woman changes slightly while consolidating the ethos that menstruation should not be visible. The menstruating woman is in constant motion, always fresh and fragrant..
Anställningsformers betydelse för häla
The subject of this study was to research whether or not different forms of employment contracts had any effect on self reported health. Whether or not any difference between these forms could be explained through the use of employee health care was also a given point of interest. To achieve this, data from the national Swedish institute of health (FHI) was used, with 6465 of the 12 166 that participated in the study. Logistic regression was the primary statistical method.Initial Chi2-analyzation found no significant difference between the two main employment forms present in Sweden. However, when the variables age, sex and level of education were held constant through logistic regression, a difference of odds at 22% between the two employment forms could be identified.
