Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :

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.

Testprogram till hårdvara på en viktindikator

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.

Ett Oskarpt Beslut : om Oskarp Logik i speldesign

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

Reaktionskrafter i dragarmarna på en traktors trepunktslyft : Teori och praktik

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

Vad bra att du kan : Barns inflytande och delaktighet i förskoleklassen

AbstractThe purpose of this essay is to study in what way teachers in preschool work with pupils enabling them to gain influence and involvement in their learning.Influence means being able to make your voice heard which is an important component of a democratic society. Involvement is about being part of a community in which everyone is welcomed regardless of beliefs and opinions. Several of today's researchers believe that learning occurs in interaction between people. Teachers providing meaningful assignments to pupils, they become more motivated to learn.The study is based on observations of how teachers work with influence and involvement in controlled sessions, and interpretations of them. My results show that children become involved in their learning when they are confronted with a variety of pedagogical approaches to learning.

Glukostillförsel peroperativt stabiliserar blodsockernivåerna postoperativt. : En jämförande studie vid planerad kolorektalkirurgi

Under en operation behöver patienter tillföras vätska. Det finns en pågående diskussion om vilken sorts vätsketillförsel som har fördelar för patienterna. Framförallt diskussionen om glukos ska tillföras eller inte. Förhöjda blodsockervärden under och efter operation har visat sig ha negativa konsekvenser för morbiditet, mortalitet och vårdtid. Det finns inga entydiga riktlinjer kring peroperativ vätsketillförsel.SyfteAtt se hur plasmaglukosvärdet hos patienter som tillfördes eller inte tillfördes glukosinfusion vid planerad kolorektal kirurgi förändrades över tid, per- och postoperativt, och hur detta påverkade diures och illamående de första fyra timmarna postoperativt.

Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

Hastighetsstyrsystem för Förarrobot : Konstruktion, Modell, Test och Utvärdering

De krocktester som utförs idag är låsta till det system av styr och draganordningar som byggs upp. Att göra en krocktest därbilarna kan styras individuellt med hjälp av en förarrobot ökar friheten att designa tester. Att krocka två bilar som på bilden på framsidan, med 90 graders vinkel mellan bilarnas färdriktning ställer det mest tidskritiska kravet när de ska träffa varandra. Detta kräver en bra hastighetsreglering vilket är huvuddelen i examensarbetet.I denna rapport redovisas hur ett sådant styrsystem skulle kunna byggas samt tester i en simuleringsmodell för denna typ av krocktest.Simuleringsmodellen är uppbyggd i Matlab/Simulink och eftersträvar att efterlikna ett verkligt sidokollisionstest tillräckligt mycket för att kunna testa styrsystemet.Efter de tester som gjorts kan man konstatera att det är möjligt att konstruera ett sådant styrsystem som kan få två bilar att träffa varandra i en sådan sidokollision som är beskriven ovan..

JAS 39A Gripens interoperabla förmåga satt i en strategisk kontext

En viktig del av en nations säkerhetspolitiska ambition handlar om att skaffa sig handlingsutrymme. Detta görs genomen orkestrering av nationens olika maktmedel. På militärstrategisk nivå skapar en samordning av politisk målsättning,doktriner och resurser en samlad nettoeffekt, vilken utgör nationens möjliga militära strategi.Efter att det kalla kriget upphört har stora förändringar i den säkerhetspolitiska miljön för bland annat Sverige ägtrum. Sverige har därför förändrat sin säkerhetspolitiska utformning och Försvarsmakten och dess luftstridskrafter harföljt efter. Det svenska flygsystemet skall idag exempelvis kunna användas i av NATO eller EU ledda fredsframtvingandeoperationer.

Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014

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.

Biologin hos svenska Lilioceris arter och åtgärder för att begränsa deras skadeverkningar :

Summary The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years. The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies. Lilioceris species overwinter normally as pupae in the soil under the host or close by. Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining. My own observations include different treatments of both lily foliage and of the leaf beetle.

The designs of the studies were of a varying kind: randomized controlled studies, comparative studies, correlative studies and descriptive studies.

Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag

The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.
