To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

AbstractTitle: The effect of caffeine on performance during resistance training ?A systematic overviewAuthor: Amanda Jonsson and Erica BenderSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2015-03-31Background: Products with high content of caffeine has in recent years become popular for optimizing physical performance. Caffeine affects mechanisms in our body which can be beneficial to perform better during exercise, but the theories have not yet been systematically reviewed.Objective: The purpose of this review article, is to examine the acute effect of caffeine intake before strength training on athletic performance with the outcome muscle endurance.Search strategy: A systematic literature search in databases PubMed, Scopus and Cochrane using keywords: ?Caffeine?, ?strength?, ?muscle?, "resistance training", "muscle strength", "strength training", "athletic performance", ?repetitions to failure?, ?muscular endurance? and ?endurance training?.Selection criteria: Healthy subjects, 16-50 years old, with experience in strength training. Studies with a caffeine intake > 5 mg/kg body weight, which participants performed dynamic strength exercises on a weight > 60% of their 1 RM.

ART, Aggression Replacement Training är en multimodal behandlingsmetod som bygger på tre samverkande komponenter. Dessa är: Interpersonell färdighetsträning där sociala färdigheter tränas, ilskekontrollträning som lär individen att handskas med sin ilska samt moralträningen som ska höja det moraliska resonerandet. 1987 började ART att användas på ungdomsvårdsskolor i USA, metoden har spridit sig och idag används ART inte enbart inom den institutionella vården utan allt mer i skolans värld.Syftet med uppsatsen är att undersöka vilket eller vilka teoretiska perspektiv på inlärning som metoden stödjer sig på och hur väl dessa stämmer överens med skolans styrdokument (Lpo 94). Studien är baserad på en kvalitativ textanalys av ART Aggression Replacement Training A Comprehensive Intervention for Youth, en bok av grundarna till metoden, samt skolans styrdokument (Lpo 94).Reultatet visar att ART vilar på flera olika teorier om inlärning, och att olika teorier finns representerade inom de olika komponenterna. I förhållande till Lpo 94 visar de delar jag analyserar på en överensstämmelse, även om någon punkt kan tolkas annorlunda..

This study aims to investigate how participants in a companys traineeprogram describe that the programmes educational tasks has prepared them for their future work. The study also examines how participants perceive that they have developed skills that are specifik to their profession and how they became part of a community. The following questions were formed to make it possible to investigate the purpose further; ?Do the participants feel that the interaction within the trainee group has promoted their learning??, ?How does the participants describe the training elements in relation to their development of competencies that they use in their professional role?? and ?How does the traineeprogram contribute to the participants becoming part of a community??. This was examined by taking part of what previous research has highlighted as important for learning and socialization in relation to traineeprograms.

Tidigare studier hänvisar till bristen av forskning som berör funktionell träning såsom corestärkande bålstabilitetsträning för att öka idrottslig prestation. Det är dessutom omdiskuterat om träning, som skapar instabilitet i anslutning till träningsövningar, förbättrar stabiliteten som i sin tur ska verka prestationshöjande. Den mest likvärda studie som har gjorts angående träningsprogram med slyngor för att stärka bålstabiliteten hos handbollsspelare med syfte att påvisa en prestationsökning i kasthastighet visar på signifikant effekt. Syftet med studien var att undersöka om ett sex veckors träningsprogram för bålstabilitet med träningsredskapet Func.Gym training bands gav en förbättrad kasthastighet hos manliga elithandbollsspelare.Två grupper användes i studien, en testgrupp bestående av sex testpersoner (n=6) med en medelålder på 22,3 år och en kontrollgrupp bestående av tre testpersoner (n=3) med en medelålder på 21 år. Alla subjekten var aktiva elithandbollslaget HK Drott. Träningsprogrammet innefattade sex olika övningar och genomfördes med hjälp av det funktionella träningsredskapet Func.Gym training bands.För att mäta kasthastigheten användes Casio EX-F1 EXILIM, inställning på höghastighet (hs) med 300 frames per second (fps).

The aim of the study was to gain a deeper understanding of the expectations that assistant nurses in the elderly care have on unit manager's leadership and the consequences if the expectations are not met. To answer the purpose of this paper a qualitative research was conducted with interviews with six assistant nurses in municipal elderly care. To analyze the empirical material communication were used as a theoretical concept. Communication includes codes, signals and messages to be interpreted by the parties in a conversation and they can be both verbal and nonverbal. This means that communication is complicated and can cause confusion if it is interpreted wrong.

This study is about how to develop younger teens problem solving ability and their social competence. The study carried through by using a qualitative method, two observations and ten interviews. The observations where preparatory for the structured interviews. The respondents where pupils in a class were it is an ongoing project which purpose is to develop childrens problem solving ability and social skills with cognitive training and an empowerment based reasoning model that is called rahyab. Rahyab is a Persian word and it means path- finding.

Through the birth and arise of the Internet people has been given great opportunities to make selective selfpresentations online, which in the long run has resulted in an easier retaining of the self- esteem than in the offline world. Simultaneously, the self- esteem has been viewed as a cause for both success and failure since it plays a vital role regarding our attitudes, emotional reactions and behavior. On this basis I wanted to study the relation between self- esteem and self-presentations closer. The purpose of the study is to describe and analyze how some users who publish training photos of themselves on Instagram experience how they present themselves within this forum and how these presentations affect/ are affected by their perceived self-esteem in their everyday life. The study is based on theories regarding self- esteem through Maslows? hierarchy of needs, the inner and outer self-esteem, and social comparisons.

Detta arbete handlar om den tekniska utbildningen i Försvarsmakten, närmare beskrivet hur en kursbeskrivning för systemmekaniker och tornmekaniker genomförs praktiskt och hur den skall genomföras teoretiskt. Uppsatsen kommer inte att behandla hela utbildningen. Den kommer bara behandladen minsta delen av utbildningen - den del som innefattar soldatutbildningen. Syftet med att skriva detta arbete är att komma fram till om den tekniska utbildningen genomförs på ett kvalitativt sätt och kontrollera om en mekaniker kan agera i subarktisk miljö efter sin genomförda utbildning. Denna uppsats är uppbyggd på följande sätt.

This essay is about integration of theoretical subjects and practical subjects at the vocational training education in a Swedish Upper secondary school. The purpose of the essay was to examine if integration of the subjects increases the students` motivation for, interest in and knowledge of the subject Swedish. Other purposes were to examine how the teachers organize their teaching of Swedish in order to adjust it to the students? interests and to examine the students? attitude towards Swedish as a subject.The essay also describes the recent development of the vocational training education of Swedish Upper secondary school and presents theories about learning and other examinations about teaching of theoretical subjects at the vocational training education.The examination carried through with a questionnaire which was distributed to the students at three programs at the school and interviews with the headmaster and two teachers. The result of the study showed that a small majority of the students believe that integration increases their motivation in and knowledge of Swedish.

The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub. Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.

Galna Glassen is a company that has a unique way of selling ice cream in Sweden. The idea is for the costumer to be able to compose their own favorite ice cream, partly by choosing the flavor of ice cream but also by picking the ingredients. The ingredients that can be chosen from are around twenty and can be everything from cookies to candy to berries. When the costumer has chosen their ice cream and ingredients they are mixed together on a cooled granite board.The company was very successful when it was founded in the summer of 2011 and decided to expand to other cities in Sweden. They also wanted to explore the profitability of a mobile sales unit that is intended for festivals and events.The thesis is meant to develop Galna Glassen?s mobile sales unit.

Rörelseanalys är ett nödvändigt verktyg då det gäller bedömning, uppföljning och diagnos vid alla de sjukdomar som påverkar den mänskliga rörelseapparaten. Idag finns det i Sverige ett fåtal kliniska gånglaboratorier dit patienter kan remitteras för att få en mer detaljerad och objektiv bedömning av deras rörelsemönster. Problemen med dessa gånglaboratorier är att de är förhållandevis dyra och resurskrävande.Avdelningen för Medicinsk Teknik- FoU vid Norrlands Universitetssjukhus har därför initierat ett forskningsprojekt där AnyMo, ett mobilt system för mätningar av rörelsemönster, har utvecklats.Målet med detta examensarbete var att vidareutveckla det befintliga systemet till att simultant kunna mäta hjärtats EKG, då det skulle göra undersökningen mer komplett.De delar som konstruerades i projektet var en EKG-sensor och en Master Unit, som kopplades ihop med en befintlig rörelsesensor (del av AnyMo-systemet). Informationen från sensorerna lagrades lokalt i ett minneskort på systemets Master Unit.Den färdiga produkten testades och utvärderades på en motionscykel vid olika nivåer av fysisk ansträngning och varierande rörelsefrekvens..

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.
