Talmotoriska avvikelser vid Parkinsons sjukdom och vid stamning: en jÀmförande studie

The following study examined whether similarities in motor speech deficits in Parkinson?s disease and in developmental stuttering could be observed. Furthermore, intelligibility was examined. Assessments of 16 people with Parkinson?s disease, 35 people with developmental stuttering and 49 matched controls were performed with the tests Dysartribedömningen and the Swedish Test of Intelligibility.

H2 För racing

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.

Möbius sekvens -Möbius sekvens samt effekter av leendekirurgi hos en person

Möbius sequence is a rare condition where affected cranial nervesoften lead to speech deviations due to reduced oral motor functioning. Thisstudy aimed to survey speech deviations, compensatory strategies and selfperceptionof speech in seven people with Möbius sequence, and to linkthese to oral motor function and intelligibility. Additionally, the immediateeffects of smile surgery were investigated in one person. The abovementioneddomains were studied instrumentally, perceptually and throughstructured interviewing. All participants displayed reduced oral motorfunction.

Modellering av rotationssystem

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

The Developmental Coordination Disorder Questionnaire 2007 som screeningsinstrument för barns motorik : en svensk valideringsstudie

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.

Optimering av motor och vÀxel i skruvdragarsystem

Examensarbete har utförts pÄ Atlas Copco Tools and Assembly system. Syftet var att utveckla ettkonstruktionshjÀlpmedel för att underlÀtta valet av elmotor och vÀxellÄda vid nyutveckling avautomatiserade skruvdragarsystem. Ofta görs valet av vÀxellÄda och elmotor individuellt vilketkan resultera i ett icke optimalt system. Genom att istÀllet göra valen tillsammans kan ett bÀttreresultat uppnÄs.Syftet med examensarbetet var att ta fram ett Matlab- script som ger en bild över hur valet avvÀxellÄda och motor pÄverkar varandra. Scriptet ska föreslÄ lÀmpliga dimensioner pÄ motor ochvÀxellÄda med hÀnsyn till hela systemet och dess uppgift.

Konceptstudie av drivmodul till bandskotare med hybriddrift

BAE Systems HĂ€gglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

Allsidig rörelsekompetens hos barn och ungdomar : En kartlÀggning av skolelevers funktionella motorik

Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.

FASOMSTÄLLNINGSMEKANISM FÖR MOTKOLVS HCCI MOTOR

Examensarbetets syfte var att konstruera en reglermekanism till en HCCI-motor. HCCImotornÀr en motkolvsmotor med variabel kompression. En motkolvsmotor Àr i teorinbÀttre Àn en vanlig motor pÄ grund av att det gÄr att utvinna arbetet frÄn förbrÀnningen itvÄ riktningar, vÀrmen verkar pÄ tvÄ ytor istÀllet för en. Huvudproblemet med dettaexamensarbete har varit att uppskatta de krafter som verkar i systemet, samt att utvecklaett enkelt sÀtt att reglera fasen mellan vevaxlarna. BerÀkningen av de krafter somuppkommer i reglermekanismen Àr komplicerad pÄ grund av att mekanismen rör sigunder körning.

Reglering av turbins ledskenor i vattenkraftverkmed hjÀlp av elektriska stÀlldon

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

YTKARAKTERISERING AV CYLINDERFODER I FÖRBRÄNNINGSMOTORER

Vid konstruktion och tillverkning av motorer idag finns flera krav att tillgodose i form av lÄng livslÀngd, lÄga utslÀpp samt liten brÀnsleförbrukning. Dieselmotorn har högre verkningsgrad Àn bensinmotorn men problemet med dieselmotorn Àr i form av utslÀpp dÀr lagstiftningen blir allt strÀngare. En del av utslÀppen frÄn dieselmotorn kan bero pÄ smörjoljan och olika motorer och ytor uppvisar olika mÀngd oljeförbrukning. Denna kan Àven variera mellan samma modell av motor. Ett sÀtt att fÄ ner oljeförbrukningen och variationen av denna Àr att mÀta ytan och sÀkerstÀlla att denna Àr optimal för dess funktion.
