Using a six-legged-robot as a development platform this thesis aimed to have a fully autonomic robot capable of navigating and mapping previously unknown terrain in three dimensions. During the project both hardware and software upgrades have been made such as implementing another computer on the robot and enabling wireless communication via Wi-Fi. Experiments were performed on a test track that
Syftet med uppsatsen har varit att bättre förstå hur unga konsumenter hanterar konsumtions- och servicemisslyckanden genom att söka en fördjupad förståelse av hur val av deras hanteringsstrategier (coping strategies) kan tolkas. Frågeställning: Hur ser unga konsumenter på konsumtions- och servicemisslyckanden och hur beskriver dem de hanteringsstrategier de använder? Metod: Kvalitativt angreppssät
A driver model can be used to predict the vehicle velocity and the energy consumption. It can be modeled such that it benefits from historical data and can be further improved if a navigation system is available. A well implemented driver model is important since the car fleet seems to be more and more electrified. The role of the driver model would then be to increase the accuracy for when the dr
Integrated modular avionics (IMA) architecture is an emerging concept in the military aerospace industry after being successfully implemented in the commercial domain. The highly modular architecture allows multiple aviation applications to execute on the same hardware thanks to defined standards by Aeronautical Radio, Incorporated (ARINC). System architects are responsible for designing and takin
60 % OF YOUNG SWEDISH PEOPLE IN THE AGES 18-25 ARE WORRIED ABOUT NOT SUCCEEDING IN LIFE. 72 % FEEL THERE IS AN IDEAL. 89 % OF THE WOMEN ARE STRESSED ABOUT LIVING UP TO THE IDEAL, 66 % OF THE MEN. THIS PROJECT IS AN INVESTIGATION OF PERFORMANCE ANXIETY. We live in a society where performances are valued so high that we believe it defines who we are. And for some reason it is okay to talk about inj
Enligt den amerikanska forskaren Richard Florida är det idag kreativitet och initiativkraft som driver ekonomin och utvecklingen framåt. Det samhälle som lyckas bäst är det som bäst tar vara på befolkningens kreativa potential och som mest framgångsrikt lockar till sig kreativa individer. Genom att analysera vilket samband som finns mellan Skånes kommuners satsningar på kultur & fritid och fasThe study aims to see if there is an impact of culture & leisure on property prices. To determine if there is a correlation method of regression analysis is used. The analysis is applied on two models, which will be called: Kommunmodellen and Staffanstorpsmodellen. Kommunmodellen consists of variables that explain property prices at a municipal level such as number of citizens, taxes, employme
Internet-delivered psychological treatment of major depression has been investigated in several trials, but the role of personalized treatment is less investigated. Studies suggest that guidance is important and that automated computerized programmes without therapist support are less effective. Individualized e-mail therapy for depression has not been studied in a controlled trial. Eighty-eight i
Background: Previous rhinomanometry studies have shown significant long-term variability of the nasal airway resistance and questioned the clinical validity of rhinomanonnetry. Research question: Could treatment with a topical glucocorticoid, budesonide, influence the long-term variability of active anterior rhinomanometry? Methods: Eight healthy volunteers participated in an unblinded controlled
In this paper, we present a random puncturing analysis of low-density parity-check (LDPC) code ensembles. We derive a simple analytic expression for the iterative belief propagation (BP) decoding threshold of a randomly punctured LDPC code ensemble on the binary erasure channel (BEC) and show that, with respect to the BP threshold, the strength and suitability of an LDPC code ensemble for random p
We have previously shown that leukotriene D(4) (LTD(4)), a known pro-inflammatory mediator, induces increased survival and proliferation of intestinal epithelial cells. In this study we examined whether LTD(4) functions via activation of the transcription factors NFkappaB and AP-1, which are potent inducers of mitogenesis. We found that the NFkappaB inhibitory protein IkappaBalpha was not degraded
This paper explores a formally grounded ap- proach to solve the problem of dynamic binding in service- oriented software architecture. Dynamic binding is a widely adopted mean to automatically bind exposed software interfaces to actual implementations. The execution of an operation on one or another implementation, though providing the same result, could turn out in different quality of service, e
Control allocation problems, in which optimal actuator values are assigned based on desired control actions and actuator constraints, are typically formulated as constrained optimization problems. Initially, only approximate solutions to the problems were deemed tractable for real-time applications. Recently however, active set algorithms have been identified as a means for solving control allocat
Electroconvulsive therapy (ECT) is an efficient and relatively fast acting treatment for depression. However, one severe side effect of the treatment is retrograde amnesia, which in certain cases can be long-term. The mechanisms behind the antidepressant effect and the amnesia are not well understood. We hypothesized that ECT causes transient downregulation of key molecules needed to stabilize syn
Syftet med artikeln är att utforska och förstå beskrivningar av och information om HPV-prevention utifrån olika positioner för att fånga samhälleliga och kulturella innebörder av HPV-vaccin. Två skolsköterskor intervjuades om sitt arbete med HPV-vaccinering, mediematerial om HPV-vaccin hämtades från Dagens Nyheter, Svenska Dagbladet och Sydsvenskans online-arkiv och informationsmaterial hämtades fThe aim of this article is to explore and understand information about HPV-prevention from several positions to grasp its social and cultural meanings. The material consists of interviews with two school nurses, material on HPV-vaccine from Swedish newspapers (Dagens Nyheter, Svenska Dagbladet, Sydsvenskan), and information from public authorities and pharmaceutical companies. In the analysis of t
Lipase has been encapsulated in ordered mesoporous materials in a one-step process. The procedure is simple and leads to well structured materials with enzyme loadings higher than those obtained through the post-synthesis approach. In the final bottle-around-the-ship material the enzyme would be entrapped in silica cages whose entrances are smaller than the enzyme itself. Therefore, reagents and p
Context. A number of large spectroscopic surveys of stars in the Milky Way are under way or are being planned. In this context it is important to discuss the extent to which elemental abundances can be used as discriminators between different (known and unknown) stellar populations in the Milky Way. Aims. We aim to establish the requirements in terms of precision in elemental abundances, as derive
Neuronal function depends on the properties of the synaptic inputs the neuron receive and on its intrinsic responsive properties. However, the conditions for synaptic integration and activation of intrinsic responses may to a large extent depend on the level of background synaptic input. In this respect, the deep cerebellar nuclear (DCN) neurons are of particular interest: they feature a massive b
