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.

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.

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: The effect of a high versus low carbohydrate intake on endurance performanceAuthor: Emma Andersson and Josefine DahlqvistSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2013BackgroundCarbohydrates play a significant role in the human metabolism, especially during training. Manystudies have investigated the effects on different carbohydrate intakes on training performance. Thescientific researchers have met a consensus in the fact that a higher intake of carbohydratescompared to a lower carbohydrate intake improves athletic performance. Lately, the increasedinterest in low carbohydrate diets has despite these recommendations gained followers globally.ObjectiveTo determine if a higher carbohydrate intake results in a better endurance performance, comparedto a lower carbohydrate intake, for adult males and females, measured as time to exhaustion, totaldistance covered and power output/cadence. To be able to give nutrition recommendations toendurance athletes based on the current scientific evidence and identify if there is need for furtherresearch in this area.Search strategyThe databases used for the literature search were PubMed and Scopus.

Vissa studier som undersökt kombinerad styrketräning och uthållighetsträningjämfört med styrketräning har funnit hämmad styrkeutveckling vid kombinerad träning. Forskning har därför riktats mot att undersöka hur hämmad effekt kan undvikas. Syftet med litteraturöversikten var att genom att granska vetenskaplig litteratur i området beskriva faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighetoch styrketräningsprogram. En beskrivande litteraturstudie gjordes på ämnet. En litteratursökning genomfördes mellan 6-24/9, 2014 i databaserna Scopus, Proquest, Pubmed, Cinahl, AMED, Web Of Sciense.

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.

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.

Due to the globalization and the changes in the market, companies have now realized the importance of a strong brand. This has led to the phenomena outsourcing. The relation between the branding consultant and his or her client has changed. Earlier the consultants worked as a single unit and were given a task to independently accomplish the assignment. Today there has to be co-operation between the two parties.

AbstractTitle: Does supplementation with omega 3 improve oxygen uptake among athletes?Author: Jonna Gustafsson and Maria Bohlin Nygren Supervisor: Frode Slinde Examiner: Ingrid Larsson Programme: Programme in dietetics, 180/240 hp Type of paper: Bachelor?s thesis in clinical nutrition, 15 hp Date: May 26, 2015Background: Previous research has shown that omega 3 fatty acids may improve cardiovascular functions by decreased aggregation and increased red blood cell deformability. This produces an increased blood flow and could have a potential effect on oxygen uptake. Optimal aerobic capacity is a determinant factor of performance within endurance exercise.Objective: To compile scientific research of the possibility that omega 3 supplementation could improve oxygen uptake among athletes.Search strategy: The literature research is based on searches in PubMed and Scopus with the terms ?Physical Endurance?, ?Oxygen Consumption?, ?Fatty Acids Omega 3?, ?Dietary Supplements?, ?Exercise?, ?Fatty Acids Essential?, ?Docosahexaenoic Acids?, ?Eicosanoic Acids?, ?Fish Oils?, ?oxygen consumption?, ?maximal oxygen consumption?, ?VO2 max?, ?athlete?, ?omega-3 supplementation?, ?physical endurance?, ??-3?, ?omega-3?, ?Maximal Aerobic Power?, ?Oxygen Uptake?, ?VO2? and ?Maximal Aerobic Capacity?.Selection criteria: Randomized controlled trials (RCT) with an intervention of omega 3-supplementation during three weeks or more were included.

During an endurance riding competition the onset of metabolic disorders leading up to elimination from the race are common. As many as 8,7 % of the horses participating in international endurance riding competitions are eliminated due to metabolic causes such as tachycardia, absence of borborygmi, hyperthermia and dehydration. To prevent the onset of metabolic disorders in the horse the rider must be able to determine the physiological and physical status of his or her horse. This requires good knowledge in nutrition, physiology and performance training. The risk of developing metabolic problems is reduced through the right feeding management and training.

Introduktion: Under de senaste tre decennierna har forskare försökt nå konsensus kring frågan om den möjliga hämmande effekten av kombinerad konditions- och styrketräning avseende utveckling av muskelstyrka jämfört med enbart styrketräning. Senaste meta-analysen inom området fastställdes 2012 och har kartlagt forskningsresultat fram till 2008, där konklusionen påvisar att forskningsresultaten är tvetydiga. Syfte: Att genomföra en systematisk litteraturstudie i form av en aktuell kunskapssammanställning över den forskning som bedrivits inom området för kombinerad konditions- och styrketräning för att undersöka om kombinerad träning har en hämmande effekt på utvecklingen av muskelstyrkan. Metod: Studien är en litteraturgenomgång där data samlats in via de medicinska databaserna; PubMed, Web of science, CINAHL, Scopus, AMED, Cochrane library och Physical education index. De sökord och sökordskombinationer som användes var; Concurrent training AND Endurance training AND Combined, Concurrent training AND Physical fitness AND Resistance training och Concurrent training AND endurance training AND Resistance training.

Two haematological instruments intended for small animal clinic use were evaluated at the Department of Clinical Chemistry, Swedish University of Agricultural Sciences (SLU), Uppsala, Sweden. The QBC-V and Vet abc were compared to a reference instrument, the Cell-Dyn 3500. Fresh blood samples were obtained from canine and feline patients from the University Veterinary Hospital, SLU. The QBC-V was used for 111 canine samples and 78 canine blood samples were analysed with Vet abc. From cats, 23 samples were analysed with both instruments.

This paper gives an introduction to the theory of minimal surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal surface and giving a brief histo- rical survey, we look at some well-known minimal surfaces and a few of their characteristic properties. The connection between minimal surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.
