This literature study summarizes the signals dogs use in intraspecific communication. The purpose is to clarify the way dogs communicate so that situations where their intentions are misjudged can be avoided. The signals are divided into olfactory, visual, auditory and tactile and every section starts with a short anatomic and physiologic description of the sense organ that is used to register the current signal type. The interspecific communication between dog and human regarding its development and function is brought up. To end with suggestions are given of how veterinary technicians in clinics can make use of knowledge about the way dogs communicate.

Policy documents in the public library field, such as the library legislation, local political goals and intra-library plan documents, often include ambitious but ambiguous formulations. This two years master?s thesis examines the relationship between four policy documents and library practice in a local context. The theoretical framework is inspired by a sociocultural theory developed by the Swedish professor of pedagogical psychology Roger Säljö. The theory emphasizes the importance of context to learning and development.The thesis? method is a case study.

This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

The study describes six upper secondary school students? thoughts of and stories about mentors and mentorship in secondary school. The mentorship has been studied with a hermeneutic approach from a narrative pupil relational perspective, which is influenced by the phenomenological humanity perspective. The aim of this study is to describe a few pupils? life worlds and to try to interpret how they describe and explain their own behavior related to mentorship and their mentors.

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.

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Filmmusic is often composed specially for a film. When analyzing film-music it seems very common to study the function of the music in a narrative context in order to see how it cooperates or relates to this narration. In the present thesis I am investigating the interaction between film and music as two ingredients on an equal level. In short: what happens when a filmmaker chooses music that has already been composed for another occasion, even in another time and a different cultural context? My aim is twofold: first to examine current film analytic strategies, secondly to find new ways of comprehend pre-composed music in relation to its new setting in a film.

Aim?Rekryteringsgruppen? (RG) is an organisation that through co-operating with the National Health service aims at optimizing the ability for physically disabled persons to rehabilitate. RG is a non-profit organisation ?using physical and mental exercise for disabled people, mainly neurologically disabled persons.? One of the goals that RG wants to achieve is ?that the target group will be able to live such an active and independent life as possible?. As no previous studies have been done in order to review the adaptation of RG:s work and its effects on the disabled, the purpose of this paper is to examine spinal cord injured individuals perception of independence concerning situation of life, ability to function and physical activity.MethodData have been collected by using three questionnaires.

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

The purpose of this thesis is to describe the work process and the results of our work with developing a web based auction system for students at Linköpings University. The present options open for students to sell objects within the University is limited to a billboard that doesn?t support bidding. Because of that a system was developed to offer an environment where they could present there objects and let demand set the final price level. A new function in this process is the option of alternate ways to end an auction with the intention of eliminating some of the problems that exists within the currently available web based auction systems with last second biding..

Swedish dairy production has during the last decades undergone considerable structural rationalisation and the number of dairy herds has decreased to less than 7000. At the same time the average herd size has increased and a large proportion of those investing in new buildings today choose automatic milking (AM). During 2008 more than ten percent of the Swedish cows will be milked with AM. The development has been faster than expected and the need for consulting has increased rapidly. This study aims to evaluate whether a check list originating from the FRISKKO (?healthy cow?) programme can be a useful tool when assessing how well the herd functions in various areas.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

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.
