Målet med detta examensarbete var att utveckla en fungerande prototyp för styrning av ett portabelt filter med varvtalsreglering och tidräkning. Om möjlighet fanns, skulle även tillval som tryckstyrning, gasindikering och flödesmätning göras. Dessa tillval kunde regleras med hjälp av fyra knappar. För att allt skulle vara lättare att hålla under uppsikt, kunde alla inställningar och värden ses på en LCD-display. Konstruktionen består av en mikrokontrollerstyrd elektronikkoppling med extern realtidsklocka för drifttidsräkning.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

Have you encountered problems when you are unlocking a door? Perhaps you have had your hands full when you needed to unlock the door? Or, you might be suffering from a disease and have difficulties to put force on to small objects. To solve these problems there are different options. The most common alternative is a key button. With the key button, you do not need turn the pinion to unlock.

Our examination project has been to develop today?s existing walking frames and make them more exiting and user friendly for tomorrow?s users.The use of a walking frame today makes it easier for a person with a movement difficulty in different extent. It makes it easier with their living condition and the user get a more movement easier life where they can take care of the daily chores without any help from the society or the family members.With our product we get a product that not only makes it easier for the user to get out and get forward. We help the user to get forward where they often would have difficulties to get forward. An example is where its more steeper parts where it could be more difficult to get up or down and even with more difficult foundation due to bad weather.

Examensarbetet beskriver analys och testmätning för att mäta uttagen effekt ur en motor som driver en massasil. Silen är bland annat avsedd för att separera föroreningar och större partiklar i pappersmassan. Ingående metoder förklaras med avseende på princip, funktion och begränsningar. Vidare testas metoderna operativt i industriliknande miljö och dess fördelar respektive nackdelar belyses. Metoderna ställs mot varandra och jämförs gällande pris och prestanda.

Bakgrund: Inflammatorisk tarmsjukdom (IBD) inkluderar ulcerös kolit och Crohns sjukdom. De är kroniska och uppkommer i skov då tarmslemhinnan blir inflammerad och sårig vilket ger en komplex symtombild med akuta diarréer, rektalblödning och buksmärtor. Behandlingen går ut på att minska symtom och förebygga uppkomst av skov. Då dessa sjukdomar påverkar det dagliga livet så påverkas också den individuella hälsorelaterade livskvaliteten, vilket mäter den fysiska, psykiska och sociala aspekten av ett hälsoproblem.Syfte: Syftet var att beskriva upplevelsen av hälsorelaterad livskvalitet hos personer med inflammatorisk tarmsjukdom.Metod: En litteraturöversikt har gjorts där tolv vetenskapliga artiklar har utgjort grunden till resultatet och skapat en översikt på befintlig forskning. De har lästs, sammanfattats och analyserats där likheter och skillnader har hittats och teman bildats.Resultat: Resultatets fyra huvudteman är Fysisk funktion, Psykisk funktion, Social funktion och Att återställa sin livskvalitet.

Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.

The purpose with my project is to evaluate how Recreational Leaders use the outdoor environment, how much they use it and why. My method was to assemble the surveys which were answered nationally by Recreational Leaders. During my project I have investigated Recreational Leaders view on the outdoor environment by reviewing a survey. Those who answered the survey find that the desire to use the outdoor environment exists; they think that the benefits of moving the teaching process outside are plenty. The children receive fresh air, they get to practise manual ability and gross motor functions, stay healthy and are able to use their imagination and creativity.

Detta arbete avslutar magisterutbildningen inom Industriell design vid Luleåtekniska universitet. Arbetet har utförts på uppdrag av Agency-9, utvecklareav Javabaserade 3D-motorer. De har tekniken för att producera dataspel avtoppklass men ingen grafisk formgivning och produktion, och är i stort behovav att få igång detta. För att visa upp funktionaliteten i deras 3D-motorAgent FX vill de även ta fram ett demo. Metoderna som använts under arbetet baseras på teorierna om systematiskproblembehandling som lärs ut vid Institutionen för arbetsvetenskap, LTU.

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

Lameness causes suffering and poor performance in sheep, as in other species. The cause of lameness often originates in problems of the claws. Many claw diseases of sheep are described in British and Australian research, but this field has previously not been of special concern in Sweden. This graduate thesis contains the first claw health survey made on Swedish sheep. The chief objective was to give an overview of sheep claw diseases and to assess claw health in adult sheep.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories. Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
