Trådlös kamerastyrning
As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

Automatiserad laddning och plundring mellan magasin
This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

The point-of-sale system we base this thesis on is Extenda Retail. Our case study is performed on Ica Kvantum in Bromölla, which implemented Extenda Retail about two years ago. Purpose: The purpose of this thesis is to figure out what important factors there are to consider, in usability aspects, when developing point-of-sale systems, with focus on the cashier.
Informationssökning och lärare: En studie av 4-9-lärare i övergången från utbildning till yrkespraktik
The main purpose of this Masters thesis is to contribute to the understanding of high school teachers information seeking behaviour in the transition from university studies to occupational practice. The theoretical framework encompasses theories of professional socialization, the sociology of knowledge, of professions, and of library and information science. The empirical material has been collected through interviews with six recently qualified high school teachers in different subjects. The interviews have been analysed on two different levels; first on a descriptive level and then on a theoretical level. The major findings are that the academic context limited the student teachers information seeking and they did not have the opportunity to choose cognitive authorities on their own initiative.
Värdering av katastrofers miljökonsekvenser
When a disaster occurs the main focus is on the loss of human lives. Here the environmental effects have been in the centre of attention. This work has had two main purposes. The first one was to formulate attributes, variables that together present a complete picture of the consequences that an event has had on the environment. The other main purpose was to investigate how people value the impact that a disaster can have on the environment.
Betydelsen av IT-stöd i problemlösning : Analysverktyg för att studera hur IT-system stödjer problemlösningsstrategier hos servicetekniker
Scania Top Team is a competition where the best mechanics in the world are competing against each other. In 2011, the world final was recorded and this material is now used to see which problem solving strategies these top of the line teams are using to solve the realistic problems assembled in front of them. To help them, the mechanics are allowed to use two of Scanias IT-systems: Scania Multi and Scania Diagnose and Programmer 3. This report consists of two parts. The first part is the development of a method to analyze the recorded material.

Patienters upplevelse av Basal Kroppskännedom efter avslutad behandling : En kvalitativ intervjustudie speglad ur socialkognitiv teori
Introduction: Basic Body Awereness Therapy (BBAT) is a treatment developed to treat different kinds of psychiatric diagnoses, but also to prevent the emergence of any other unhealthy conditions. The treatment is aimed to increase the body control and conscious breathing but also requires mental awareness.Aim: The aim of this study is to, based on social cognitive theory, describe patients' experiences of BBAT performed as group therapy.Method: The study design was qualitative with an inductive approach. Five people were interviewed after a BBAT group treatment in primary care. The data was collected by individual interviews with semi-structured questions and the interviews were analysed by qualitative content analysis.Result/Conclusion: The participants experienced increased body awareness and implemented BBAT strategies even though the treatment frequency was insufficient. BBAT was described as helpful used to regulate intensity level, stress management and facilitate breathing.

Välbefinnande och Kognitiv Prestation : En experimentell studie om positiv sinnesstämning främjar kreativitet och flexibelt tänkande
The purpose of the study was to investigate, through an experiment, if positive mood promotes creativity and flexible thinking. Participants were a total of 93 college students. The main hypothesis was that subjects induced with positive mood would perform better than subjects induced with negative mood, at a test reflecting creativity. To further explore the implications of priming (subliminal manipulated moods), a neutral control group was included. The cognitive test used in the study was Duncker´s The Candle Problem, a test which aims to get the subjects to apply flexible and creative thinking.

Nyblivna mödrars erfarenheter av initiering av amning : En jämförelse mellan tre kliniker
ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method: Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine. Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.
Att balansera Management Control Systems - En fallstudie av ett litet svenskt IT-företag
This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.
Får högpresterande elever den utmaning de har rätt till i skolan? : En empirisk studie baserat på lärares åsikter om arbetet med individualisering med fokus på högpresterande elever
The purpose of this study is to investigate five teachers? opinions on the work with individualization with focus on above-average pupils. I have issued four questions based on the purpose of this study: - How do these teachers define the theoretical concepts of individualization and above-average pupils? - How do the teachers reason about the concept of individualization with focus on the above-average pupils? - How do the teachers reason regarding the work with individualization in the Swedish language? - Do these teachers consider that there are difficulties to individualize the work so that it will challenge above-average pupils?The method used to conduct this study was a semi-structured qualitative interview with five teachers in primary school. The theory and the theoretical concepts this study is based on is: what defines the above- average pupils, the zone of proximal development, the concept of individualization and motivation and the importance of cognitive and non-cognitive abilities.The study shows that the theoretical concept of above-average pupils is hard to define and it shows a difference between how the teachers choose to define it.
