The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

What is it that drives a person with criminal behavior to change their lifestyle? What are the obstacles to a lifestyle change? These issues have been guiding us during this study. In the introduction, we describe the previous research that has been done among crime in men. The themes that will follow us through the course of the study are as follows; cause of crime, Self-efficacy, social network and lifestyle change. The aim of the study was to investigate the factors that a former prison convicted individual believes has been significant, as they break their criminal behavior associated with a lifestyle change.

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

AbstractThe purpose of this study is to examine whether the individual influence at the working place leads to the perception of decreased stress. Also I looked at whether stress and individual influence is affected by the employees age, sex or employment years. Previous research shows that individual influence decreases stress but strangely enough do the research show that individual influence seem to decrease in today?s work environment. This research is quantitative with questionnaires, answered by 74 civil servants working in a department in the municipality of Karlstad.

The definition of procrastination can be described as a behavior with deliberate postponement of tasks or commitments despite expected negative consequences for the individual and his or her environment. This study examined how widespread this behavior is among students in higher education in Sweden. Using a web-based survey, data was collected for analysis. A statistical program, SPSS, was used for evaluation of the collected data. The purpose of this study was to examine whether there are differences in the degree of procrastination between students located on campus versus students who do their education at distance.

The combat mission is an extreme situation with high demands of the soldier. Killing might very well be necessary. Before a mission a soldier can experience stress due to these factors. The purpose of this paper is to find methods to handle stress due to an upcoming combat mission and to the prospect of having to kill. The main questions of this essay: -How can certain parts of the physiological psychology improve a soldiers ability to perform a mission? ? Is the Swedish soldier mentally prepared to kill? The theory for this essay has been described using litteratur by experts within the field, and the results thereafter discussed.

Transcending sound design is possible. There are unseen possibilities and a great potential for improvement and development in sound and music design ? but there is a great difficulty penetrating the obstacles that lies in the way for such development to take place and to exist. The difficulties in being negotiable and productive lies more within the limits of the audience it has to gain, than in itself. It is as though music and sound design has to evolve very slowly, in an almost evolutionary style; one step at a time, to be accepted.

Bakgrunden till detta examensarbete var att Qumex Materialteknik vid ett flertal tillfällen konstaterat att material av typen SS 0725 har uppvisat bristfälliga härdresultat. Materialet, som är relativt nytt på marknaden, är ett gjutjärn av typen segjärn och utmärker sig gentemot andra segjärn på grund av sitt höga innehåll av kisel. Då segjärn enligt den nu gällande EN-standarden klassificeras efter sina mekaniska egenskaper uppstår ett problem gällande SS 0725. Materialet uppfyller de krav som är ställda för EN-GJS-500-7 och hamnar därmed under samma materialbeteckning som ett segjärn med betydligt lägre kiselhalt. Att två material med olika kemisk sammansättning hamnar under samma beteckning kan innebära problem.

AbstractMy purpose of the investigation is to enter deeply into the knowledge of the Individual plan of the development and to examine how teachers, pupils and parents look at the Individual plan of the development and the purpose of the Individual plan of the development in school. My question of the main problem in this investigation was to examine the expectation on the Individual plan of the development from teachers, pupils and parents and if the Individual plan of the development has been influence the cooperation of parents and the influence of the pupils also how and if teachers, pupils and parents apprehend some kinds of changes.The review of the literature begin with a closer study about our document of control, witch are the curriculum of the compulsory school (Lpo 94), The National Agency for Education General Advice for the Individual plan of the development (2005), a study of the development of the cooperation of the parents and the influence of the pupils under the years of research about it.I have in my investigation used qualitative interview in different forms like the ordinary interview, interview on telephone and focussed group interview with teachers, pupils and parents. The result of my conclusion from the investigation is that the information and the knowledge of the Individual plan of the development are important to be able to increase the influence from the pupils and a different cooperation from the parents in the development of the school with the Individual plan of the development. My examination is small and not generalised but I believe that it still can represent the attitude of the Individual plan of the development. The consequence of the investigation shows that pupils and parents have vague idea of the Individual plan of the development.

Denna undersökning är ämnad att utforska högstadiekillars syn på de bakomliggande orsakerna till det faktum att deras grundskolebetyg är sämre än tjejernas, och att denna skillnad ökar. Analys av intervjuer med de 31 medverkande killarna gav ett antal möjliga förklaringar, bland annat; bristande planeringsförmåga, en odefinierad optimism om framtiden samt en instrumentell-strategisk inställning till betyg..

Power, Criminality and the gamble about bordering normality. From theperspective of Foucault. This study is about how criminality becomes a strategy of power used by the individual to overcome difficulties and gain advantages. This strategy of power sets loose a process of identity formation within the individual that gives shape to his own norms which are opposite to the one of the society. The individual norms and the normative society cooperate with one another in a cultural teamwork.

The term ?health maintenance? was introduced in the 1960?s. A common conception nowadays is that health maintenance is always beneficial. Gestaldo (1997) meant that health education on one hand could give the individual a feeling of autonomy, but on the other hand also put the individual in an inferior position where the teacher represented ?the truth?.

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.
