Undersökning av informationstavlor : ur ett kognitivt perspektiv
I detta examensarbete undersöks hur informationstavlor vid Volvo PV AB, motor, Östra fabriken, Skövde påverkar montörerna som arbetar där i deras arbete. Uppdraget som undersökaren fick av Volvo var att undersöka vilken betydelse de informationstavlor som sitter vid varje modul/arbetsstation spelar i det dagliga arbetet. De här informationstavlorna visar hur många motorer som ska produceras per vecka. Metoden som användes i undersökningen var en kvalitativ intervjubaserad undersökning, med 24 deltagande montörer.Resultatet visar att den information som fås via tavlorna är av stor vikt och behövs i någon form. Det finns dock vissa betydande brister som påverkar montörerna negativt på olika sätt.
Mätning av Emissioner från en Diesel Motor under Transient Driftförhållande
Transient driftförhållande blir allt mer intressant för forskare och tillverkare och de största svårigheterna är att minska emissionerna utan att påverka bränsleförbrukningen eller motorns respons vid gaspådrag negativt. Huvudmålet med det här examensarbetet var utvärdera olika metoder för att mäta NOx och antal partiklar med hög tidsupplösning för att möjliggöra studier av emissioner under transient driftförhållande.I arbetet har en Horiba MEXA 120NOx NOx-sensor studerats med avseende på linearitet, mätsäkerhet och responstid. Försök för att öka noggrannheten har också gjorts genom att kompensera för varierande skalfaktor för utsignalen och för responstiden.Ett spädsytem har arbetats fram för att ge hög tidsupplösning och god repeterbarhet. I detta ingick en Rotating Disc spädare och en två-stegs Dekati spädare. Spädsystemet var kopplat till en TSI Ultrafine Condensation Particle Counter 3025 A (CPC) och var nödvändigt för att hålla koncentrationen inom det mätbara området.
Rekonstruktion av mimesis : Ett försök att tänka begreppet mimesis utifrån Paul Ricoeur och inifrån Martin Heidegger
This essay tries to investigate the possibility to reconstruct the concept of mimesis in Martin Heidegger?s hermeneutical phenomenology in Sein und Zeit. Paul Ricoeur?s interpretation of the concept of mimesis in Aristotle?s Poetics, develops a new temporal understanding of the mimetic activity, which Ricoeur in his work Time and Narrative, claims to have the possibility to overcome the aporias in the phenomenology of time. With this criticism as the background context for the present study, seeks this essay to pick up Ricoeur?s new conception of mimesis, and use that in a comparative philosophical reflection on the basic concepts in Heidegger?s Sein und Zeit.
Energianalys av luftbehandling
Elanvändningen till ventilation har ökat med 40 % sedan 1990 i Sverige. Ventilationen är en miljöbov enligt undersökningar som visar att elanvändningen till ventilationssystemens fläktar kan reduceras. Minskning av elförbrukningen kan t.ex. uppnås genom utbyte av fläktmotor till en EC-motor eller till en fläkt med bakåtböjda skovlar och direktdrift. Effektivieringsåtgärder kan ge en lägre elförbrukning på upptill 50 % i vissa applikationer.Ventilationsfläktarna i Sverige förbrukar 12,3 TWh per år.
Fo?rba?ttringsfo?rslag pa? automatisering av bagagehantering
This report will outline a proposal for the improvement of the baggage sorting facility at Arlanda airport. Swedavia is a state owned company group that operates, owns and develops airports in Sweden. One of their main roles is to create accessibility needed to facilitate and streamline the work at the airport.Swedavia is constantly working to develop new solutions and enhancements that will help to standardize and automate the work at airports without major impact on climate and above all adapt these solutions to work.The project has been aimed to identify and isolate the problem at the check-in counter, investigate the possibility of setting a speed control on the DC motor driving the luggage conveyer belt at the check-in desk so that the luggage does not lose tracking already there, as well as evaluate the new sorting systems planned to be introduce in the upcoming refurbishment of the sorting area.To determine the parameters that are used to regulate the speed of the baggage conveyor belt, information about the inputs and outputs that participated in the process was gathered. Information was collected both practically and theoretically. Process was followed and monitored by the supervisor of the company, and a theoretical study was done separately on my own.
Thailändska kvinnor och mötet med den svenska kulturen : Har det sekulariserade svenska samhället påverkat deras buddhistiska tro?
The purpose of the study is to observe how the participants of the study interacted musically through verbal, non-verbal and musically resonant expressions. Verbal communication was expressed in discussion of the music's tempo and to clarify for ensemble participants from where they we?re going to play and sing. Non-verbal communication could be used to gesticulate an instrument or a melody. For example, the movement of a hand could symbolize notes on a musical stave to indicate the notes placements.
Bjud inte med armbågen! : -en studie om marknadsföringsstrategier inom hotellbranschen och hur dessa implementeras på de bokare som verkar i Umeå.
AbstractReading books to children is often an integral part in preschool activities. The purpose of thisstudy is to investigate how educators think about the educational function of literature inpreschool activities. I have in my study used qualitative interviews with active educators andobservations to answer my questions about why the educator reads to the children, how theeducator thinks about the choice of literature and if the literature can contribute to thechildrens development and if so, how. The knowledge- and research background presentsliterature and previous research done on the subject. The results of my study shows that theeducators have many thoughts about the importance of literature in preschool.
AKK - Alternativ och Kompletterande Kommunikation : AKK som stöd i den dagliga förskoleverksamheten
This study was built on the concept of Emotional Intelligence (EI) as an ability with four branches, to effectively: (1) perceive (2) reason (3) understand and (4) manage emotions. By closely studying the four processes of EI through eight semistructured interviews with psychologists, counselors, CBT-therapists and psychotherapists, a study of participants' stories from real practice was done and then analyzed and interpreted. The purpose of this study was to get the participants to describe and put words on practical experiences that occur with clients that correspond to the four domains that define the concept of EI according to Mayer et al. (2008) and find out about if their way of "doing" EI gets trained and developed after several years of professional activity. The results shows that the practitioners used all four branches of EI in dialog with the client, both intra- and interpersonal.
Playplus : Utveckling av produktkoncept för aktivitets- och inlärningsmotiverad lek
In a society where adults set the conditions for children?s play and generate modern and at times technically advanced products, fundamental characteristics like simplicity, opportunities for motor skills training and learning tend to be neglected. Owing to this, the Linköping-based company Time In wants to introduce a new multifunctional product, which differs from other products in shape and function and lives up to the often overlooked, basic characteristics in a toy.With Time In as the assigner, the purpose of this master thesis has been to use simple means to produce a "learning by playing" concept. Since Time In sells toys and products suitable for children in nurseries and preschools, the development of the products has therefore included a study of nursery and preschool environments.The thesis has been carried out within the Product Design subject area at the Department of Management and Engineering at Linköping University. Concept development has been done in three phases: the Preparation phase, the Design phase and the Presentation phase.

Stadsrum för barn : en skolgård som mötesplats
In my opinion, the city is a place fit as much for children as for grown-ups. I
have noticed, however, that this is not a view shared by everyone.
Does not the urban space belong as much to children as to other people?
Yes, of course. Today and in the future most people will live and grow to be
adults in cities. I would even take it as far as to say that without children,
there will be no real city.
Åtgärdsprogram för elever med svenska som andraspråk : En jämförande studie av fyra elevers åtgärdsprogram i två skolor
One of the essential needs of human beings is to be involved in a social context. The intention of this study was to see if the opportunity to have an iPod Touch, could make it possible for students with literacy difficulties to participate in the regular classes and if the implementation of iPod Touch in the school setting would result in informal learning outside the school. In this case study two pupils with literacy difficulties have been using an iPod Touch in their daily school activity. The pupils as well as their teachers have been interviewed about their experiences of implementing iPod Touch as a tool in the regular classroom teatching. The results indicate that iPod Touch can help students to be in inclusive education and that they use the iPod Touch outside school.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
Landskap för spontanidrott :
"Landscapes for Spontaneous Sport"
The main aim with this degree thesis is to show how planning and design of urban space can promote spontaneous sport. Public health and urban life would benefit from re-introducing the sport and physical activity in the townscape.
The study can be seen as an "inspiration book" that focuses on the connection between sports and landscape architecture. The starting-point for the discussion is the fact that the spontaneous sport is on the decline and the main general question is how this negative trend could be broken. In particular the study asks how landscape architecture could promote and increase spontaneous sport.
Good examples of places for spontaneous sports of different kinds are given, both from Sweden and from other countries, which have inspired a case study where I propose a redesign of a centrally located, but hardly used park in Skäggetorp, a suburb of the town of Linköping.

Uppstagning av grenrör för Volkswagen rallycrossmotor
Denna rapport är ett examensarbete utfört av Per Jonsson, student vid Karlstads Universitet. Examensarbetet omfattar 22,5 högskolepoäng och är ett obligatoriskt moment inom högskoleingenjörsprogrammet i ämnet maskinteknik. Företaget Trollspeed tillverkar högeffektiva racingmotorer för användning av racingteam på elitnivå. Stora turboaggregat samt tillhörande utrustning sätts samman med specialbyggda avgasgrenrör för att uppnå största möjliga effektuttag. Tillsammans bildar dessa sammansatta delar en hög vikt och måste därför stagas upp. Detta arbete handlar om att ta fram en ny lösning för uppstagningen, då dagens lösning leder till oundviklig spänningspåverkan i grenröret som bidrar till att sprickbildningar uppstår. Projektet är indelat i två delar där första delen omfattar framtagning av ett mätverktyg för analysering av rörelse samt kraftpåverkan hos grenröret. Framtagningen av mätverktyget resulterade i en mätskala med visare för visualisering av rörelser och monterade lastceller för analysering av kraftpåverkan.
