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.

Social workers in this study describes various experiences of the assessments of interventions for children and adolescents. Social workers experience of the many different situations where an assessment of best effort must be made on the basis of BBIC, which is the Social Services investigation records. To make this assessment, the Social workers need social assistance and support of their colleagues and manager. Knowledge mixed with experience is also an important part when it comes to being professional and not let emotions control that could otherwise be happened when the social worker meets and builds relationships with clients. Social workers are also those who will decide which achievement the client needs from the needs.

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

Smärta är en unik upplevelse som enbart den drabbade kan bedöma. I sjuksköterskans arbetsuppgifter på en akutmottagning ingår att se till varje patients unika behov. För att inte ett vårdlidande skall skapas för patienter med smärta är det viktigt att en korrekt behandling för smärtan ges. För att detta skall kunna ske krävs att sjuksköterskan på akutmottagningen, dels har god kunskap om smärtlindring dels vet hur smärta kan utvärderas på ett adekvat sätt. Syftet är att beskriva resultat från kvantitativa studier som undersökt överensstämmelse mellan patientens subjektiva smärtskattning av akut smärta och vårdpersonalens skattning av densamma.

This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.

The essay treats how a process of implementation was executed and the teachers? relation to two curricula, Lpo94 and Lgr11, with two different grading systems, which have functioned as models for one and the same year. The purpose is to investigate the ways in which a change in curricula and syllabus affects teachers in their teaching and assessment practice in the subject of Swedish at secondary school. The investigation had a phenomenological approach and was executed by means of in-depth interviews, questionnaires and one observation. The results are based on a methodological triangulation with qualitative and quantitative data where visible similarities and differences are brought out.

Spelmotor är benämningen på den komponent som hanterar en del av mekaniken i ett datorspel. Förutom funktioner för grafik, fysik etc. finns också funktioner för rörelser, interaktion med världen etc. I detta examensarbete går vi in på hur en spelmotor för morgondagens mobiltelefon kan se ut, samt vad dagens mobiltelefoners hårdvara och mjukvara saknar för att dagens PC-spel ska kunna portas till dem. Stödet för att spela avancerade spel på mobiltelefoner växer ständigt och inom några år bör hårdvaran vara ungefär densamma som på PC.

Communication during the process of Environmental Impact Assessment: Interviews concerning three infrastructure projects Environmental Impact Assessment (EIA) is a method to describe the possible impact of a planned project. The aim of such an assessment is to aid a sustainable development, by supplying a comprehensive basis for decision-making. Today there are many people working with EIA in different forms, representing both different interests within the community, as well as having different individual points of view. The proponent is responsible for the EIA, but it is of interest to study the relationship between the different participants who are involved in this process. The aim of this report is to study how the different disciplines involved have communicated with each other and amongst themselves, what characterises good communication, and if anything should be improved.

Syftet med det här examensarbetet är att beskriva hur lärarens bedömning kan påverka elevers lärande positivt samt att undersöka vilka bedömningsformer lärare använder sig av. Med vårt examensarbete vill vi utöka vår kunskap om bedömning och beskriva vilka konsekvenser olika syften med bedömning kan få för eleven. Vårt mål är inte att generalisera, utan att ge en bild av vilka uppfattningar som kan finnas hos lärare. Vi har genomfört fyra kvalitativa intervjuer med lärare i år 4-6 och det är deras utsagor samt relevant litteratur som examensarbetet bygger på. Formativ bedömning, dvs.

Theory of mind involves the ability to take another person?s perspective in thought, emotions and intentions.  There is today a lack of instruments to assess children?s development of Theory of Mind (ToM) in Swedish. ToM is considered by many scientists to be the basis for development of pragmatic competence. The relationship between these two abilities is complex and not fully resolved. Both abilities are important components for the development of social skills.    The purpose of this study was to compare 4 and 5-year olds ToM-ability measured with a Swedish version of Wellman and Liu?s ToM-scale, Sally Anne and Social Emotional Test with estimated pragmatic competence measured with the Children?s Communication Checklist (CCC).

I robotikkursen Autonoma Mekatroniska System på Halmstad Högskola finns ett problem som kan uppstå vid bygget av deras hjulförsedda mobila robotar. Studenter har en tendens att bygga roboten så att den körs med maximal effekt från start till inbromsning. Detta medför att vid test av deras robotar så slits motorerna ut fortare vilket ger en onödig kostnad. För att minska på kostnaden är målet med detta projekt att bygga och reglera en sådan robot med hjälp av en banplanerare. Banplaneraren skapar mjuka övergångar vid start och inbromsning av roboten vilket gör att motorerna inte slits ut lika fort.I detta projekt ska vi utveckla en robot som kan användas som ett pedagogiskt undervisningsmaterial.

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.
