Kampen för ökad tillgänglighet : - om enskilda aktörer, policynätverk och förhandlingsarenor i utarbetandet av EU:s bussdirektiv
The Motor Group of the European Council was commissioned in the autumn of 1997 to prepare a proposal for a new European Bus and Coach Directive. In the beginning, most of the Member States did not have the accessibility requirements as their main concern; still a smaller network with actors from the National delegations from Britain, Germany and Sweden would influence the other National delegations in the Council group to finally agree to retain the requirement of accessibility of the Directive. Within the EU decision process, the European Disability movement acted as a strong player during the whole negotiation process using the proposal to a new Bus and Coach Directive as a tool to influence key actors to go towards a Directive with a strong approach for accessibility.Policy Transfer and Policy Transfer Network are used as analytical tools to understand and structure the transfer of the question of accessibility during the negotiation process. Actors understanding how the bureaucratic process works within the EU decision system have a chance to contributing for the changes in the directions they wishes for within a range of policy areas. The principal aim of the Directive was to guarantee the safety of passengers and to provide technical prescription in particular to wheelchair users.
Seniorers motivation till motion : En kvalitativ studie om seniorers strävan mot ett aktivt och friskt liv
This qualitative study investigated what factors influenced older adults to motivate themselves to continue to be pshysical active in their later life. Six individuals, both men and women in the ages of 65-89, were interviewed. The interviews were analysed by informal content analysis. The results showed that there is a certain group who had a strong will to lead a long, well-conditioned and sound life. Although, the seniors are getting older, they continue to make active choices about physical activity on a daily basis.
Museers marknadsföring mot hotell : Hur marknadsföringen har ändrats sedan återinförandet av entréavgifter
This study's main objective was to identify adolescents participation in alternative sport activities and which kind of physical activity that was preferred by adolescents who didn't had any earlier experience of sport clubs. The study combined interviews and surveys with the purpose to get both adolescents and sport leaders perspective. A total of five interviews were performed and fifty-four surveys was collected. The results showed that adolescents already physical active were those who participated in alternative sport activities. Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..
Effektivare produktframtagning vid kundanpassning
Huvudsyftet med detta examensarbete var att ta fram ett regelverk för hur Hägglunds Drives AB kan effektivisera framtagningen av kundanpassade axeladaptrar för montering mellan utgående motoraxel till kundaxel. Ett beräkningsprogram skapades i Excel som guidar konstruktören genom skapandandet av en adapter. Till beräkningsprogrammet kopplades en parametriserad CAD modell av en adapter. På så sätt går det med en knapptryckning i beräkningsprogrammet skapa en CAD modell med den av beräkningsprogrammet föreslagna utformningen med rätt toleranser och mått. Möjligheten finns även att automatiskt generera ett ritningsunderlag på en 2D ritning.
Sensory nerve conduction studies in young adults for the expansion of a reference material
Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.
Hur skall den totala vårdkostnaden för en hjärtprodukt beräknas? : En fallstudie av tre hjärtprodukter vid Hjärt- och Medicincentrum på Universitetssjukhuset i Linköping
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Modellering och design av elmotor för mutterdragare
This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.
En SOA utvärderingsmall med fokus på integration, arkitektur och tjänster : Ett praktikfall på Logica
Today, there are no standardized ways to characterize SOA, many are talking about SOA and many say they are using SOA. One way that we have chosen to characterize this phenomenon is through an evaluation that will indicate whether SOA have been used in the development. Basedon a Service Oriented Architecture literature study, we have created an evaluation pattern resulting SOA principles of integration, architecture and services. This evaluation was applied to Logica's own integration system AgrCom through an empirical study to result in a response indicating whether AgrCom is SOA based. The results of the evaluation show that AgrCom is part of an SOA solution but not an SOA as a whole concept.
Övervakningssystem för båtelektronik
Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
Trådlöst elektriskt lås
Syftet med examensarbetet är att göra en trådlös version av det elektriska lås som tillverkas av Electec System AB.För att göra ett trådlöst elektriskt lås måste ett batteri monteras i låset. Batteriet måste hållas uppladdat hela tiden för att kunna driva motorn och ge strömförsörjning till elektroniken i låset. Alla signaler mellan låset och styrenheten ska dessutom överföras trådlöst istället för med kabel. Signalerna måste kodas innan sändning så att ingen obehörig kan läsa signalen och sedan öppna dörren.Det svåraste i ett trådlöst elektriskt lås är att överföra effekt från dörrkarmen till låset eftersom utrymmet är begränsat och avståndet mellan låsblecket i karmen och låset i dörren kan uppgå till 10 mm. För att överföra effekt från dörrkarmen till låset konstruerades en transformator.

Schur AB är ett företag i Eksjö som erbjuder sina kunder lösningar inom post- och tidningshantering. Bland dessa lösningar ingår ett transportsystem kallat Gripper TGG 3200 vilket transporterar tidningar från exempelvis pressen till olika enheter i packsalen. Transportsystemet drivs av ett antal asynkronmotorer, antalet motorer variera med avseende på hur lång transportsträckan är. Då drivstationer och motorer är de dyraste komponenterna i transportsystemet vill man minimera antalet av dessaSystemet är uppbyggt av aluminiumprofiler som gör att det kan skräddarsys efter kundens behov. I profilerna rullar enheterna som transporterar tidningen i en sammanlänkad kedja.
Mätning i nätstationer - nyttor och problem
The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.
Degradering av grate-plattor i ett Grate-Kiln system
Det här examensarbetet går ut på att utreda vilken påverkan oljeval och inkörningsmetod har på tätning mellan kolvring och cylindervägg i en fyrtaktsmotor. Arbetet har utförts på en motorcykel av märket Honda och modellen heter CBR 954 RR årsmodell 2003. Det diskuteras dagligen i tidningar, på internet och i garage runt om i världen om vilken typ av inkörning som är effektivast för att få en motor att gå bra och hålla länge. Vissa bil- och mctillverkare har helt tagit bort sina inkörningsrekommendationer medan andra fortfarande har kvar rekommendationen att man ska köra lugnt och på låga varvtal under ett visst antal mil. Eftersom att inkörningen påverkar väldigt många parametrar så finns inte möjlighet att testa hur olika oljeval och inkörningsmetoder påverkar alla dessa parametrar.
"Svergies bästa hus!" : En kvalitativ studie om hälsofostran och demokratisk värdegrund i ungdomsverksamheten Rapatac
På grund av ett intresse för de olika metoder som använts för att kunna arbeta på ett effektivt sätt med barn och ungdomar, valde jag en specifik ungdomsverksamhet. Verksamheten är, på grund av sina avskiljande metoder, unik jämfört med andra ungdomsverksamheter. Stränga och klara regler samt direkta åtgärder är några av de avskiljande metoderna. Då syftet med undersökningen var att undersöka Rapatac?s syn på hälsofostran, och tillämpningen av demokratisk värdegrund i praktiken, gjordes studien i form av en kvalitativ undersökning inspirerad av narrativ teori.
