Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

This study consists of a literature study and a survey in Tamil Nadu, India. The aim of the study was to get an understanding of horse feeding in tropical climates and what kind of feeding related problems that could occur because of the fodder. Information and data were collected from eight different stables and from Tamil Nadu University of Agriculture in the region of Tamil Nadu in March-April 2009. The horses in Tamil Nadu were given rice straw, unknown grass, Cynodon dactylon, lucerne, maize, Pennisetum glaucum x Pennisetum purpureum hybrid and Chloris gayana as roughage. As concentrates, the horses were given wheat bran, oats, barley, soybean meal, maize, carrots, coconut cake, peanut cake, horse gram and chick pea.

As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.

About 10 % of the adult women population in Sweden are treated annually for urinary tract infections. The increasing bacterial resistance towards antibiotics is classified by WHO (World Health Organization) and ECDC (European Centre for Disease Prevention and Control) as one of the greatest treats for human health in a global perspective. To find alternatives scientists are studying the possibility to use probiotics to reduce the frequency of recurring urinary tract infections. This literature study examines five randomized double blinded placebo controlled studies where different strains of Lactobacillus have been used as a prophylactic to women suffering from recurrent urinary tract infections and bacterial vaginosis. Overall the studies do not display enough promising results to recommend the use of probiotics as a prophylax or cure..

Matsvinn förekommer i hela livsmedelssystemet och har en negativ påverkan på både miljö och samhällsekonomi. Miljökostnaden för varje kilo matsvinn blir högre ju mer förädlad varan är. Denna studie har utförts på uppdrag av Regionservice Måltid inom Västra Götalandsregionen. Syftet är att identifiera vårdspersonalens uppfattningar om bakomliggande orsaker till orörda matbrickor på två sjukhus i avsikt att belysa möjliga förbättringsåtgärder. Frågeställningarna är: Vilka rutiner har medarbetarna på respektive avdelning kring beställning av matbrickor? Hur sker beställning och avbeställning av matbrickor på respektive sjukhus? Vad är grundorsaken till orörda matbrickor? Vad kan avdelningarna respektive köket göra för att minska antalet orörda brickor? I studien används en kvalitativ metod där empiriska underlag bygger på intervjuer och kortare observationer.

In the year of 2001, China launched their new international marketing strategy Going Global. As an effect of this, the frequency of Chinese establishments in Sweden has increased heavily in the last ten years. One of the larger Chinese establishments in Sweden happened in 2003, by the telecom company Huawei. This essay illustrates the obstacles that a Chinese company faces when setting up their business on the Swedish market. Previous studies have focused on Swedish establishment abroad.

I denna uppsats betraktas två olika bandspridningstekniker och vilken påverkan de har på telekrigsförmågan. Uppsatsen svarar på frågan:Vilka möjligheter finns att bedriva signalspaning och störning mot radiokommunikation som använder bandspridningsteknikerna frekvenshopp eller direktsekvens?Inledningsvis beskrivs en modell för telekrig mot radiokommunikation, ?telekrigcykeln?. Därefter beskrivs principer för ett radiosystem samt de två bandspridningsteknikerna frekvenshopp och direktsekvens. Slutligen analyseras bandspridningsteknikernas påverkan med hjälp av telekrigcykeln och resultaten diskuteras.Uppsatsen kommer fram till att båda signalerna går att spana mot, direktsekvens innebär större svårigheter för signalspaningen än frekvenshopp.

En av Glimek AB:s mest förekommande maskiner är SD-180 som används för degavvägning. Den finns i flera olika varianter. Den enklaste har enbart start- och stoppknapp och en potentiometer för att ställa hastigheten och en mer avancerad variant har en operatörspanel där olika möjligheter till inställningar finns.Konstruktionen på denna maskin hade inte uppdaterats på många år och behövde en uppdatering av användargränssnitt, programvara och elkonstruktion. Arbetet har framförallt koncentrerat sig på användargränssnittet till panelen.En del av arbetet var att undersöka om det var möjligt att utesluta PLC ur konstruktionen och använda en mer avancerad programmerbar frekvensomformare. Eftersom det blev problem med lanseringen av programvara till frekvensomformaren och enbart en mindre bra fungerande demoversion fanns tillgänglig så var detta tyvärr inte möjligt.I arbetet har olika varianter på operatörspaneler utretts.

Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

The purpose of this study is to examine how school meals are organized in a selection of Stockholm's secondary schools and to examine the relationship between school meals and the different parameters that indicate each school's symbolic capital and educational capital. By looking at the statistics from each school on the basis of the final grade average, percentage of pupils with foreign background and gender, I examine whether it is possible to see a relationship between how schools organize meals and which pupils attend the school.  In my study, I systematically went through each school's website and tried to identify how school meals at each school are organized. To increase the validity of the study, I have also conducted a questionnaire survey by mail addressed to school principals.   In order to analyse and understand my results and put them in relation to my current knowledge about the schools in my sample, I am using Bourdieu's theoretical tools that a given aid, both in methodological and analytical purpose. Based on Bourdieu's theories of symbolic capital, cultural capital and educational capital, I can understand and analyse school meals are organized and focused as part of schools' symbolic assets in competition with other schools.   The first part of the study shows that there are four different organizational models for school meals, fully equipped kitchen and canteen, heating kitchen and canteen, school meals in restaurants and school meal card.    In the second part, I have examined the relationship between the type of organization for school meals used and the symbolic resources available at the school. I can conclude from the results that it is difficult to find a correlation between the symbolic resources and the different categories. But even though it is not possible to see all the schools' symbolic assets equally clear, there are still some very telling examples. In many ways, these examples can be seen as polar opposites to each other based on Mikael Palme?s concepts ?goal rational? and ?education oriented? schools..
