The study comprises an experiment and an in-depth study in which a pre-test and a questionnaire were used. Nine deaf signers, two persons with dyslexia and 12 persons without any perceptual or cognitive constraints participated. Of these 23 persons, seven were selected to take part in the in-depth study.

Kylfläns till förbränningsmotor hos radiostyrda tävlingsbilar

Inom Radiostyrd Bilsport tävlas det med ett antal olika klasser som drivs av 2-taktsförbränningsmotorer. Dessa blir mycket varma och måste kylas av. Det sker med hjälp av enkylfläns som är monterad ovanpå förbränningsrummet, och som kyls av fartvinden.HP Hobbyprodukter har frågat oss om vi kan hjälpa dem att ta fram en egen kylfläns åt dem.Eftersom det ofta förekommer ovarsam behandling i tävlingssammanhang, är det ett krav attkylflänsens ska tåla detta. Den måste även avleda värme från förbränningsrummet, motorblocketoch övriga motorkomponenter effektivt. Ett önskemål är att kylflänsen ska ha ett unikt utseende,så att den är lätt att känna igen ute på banan.Arbetet har inriktat sig på prototypnivå.

Konceptstudie av Waste Heat Recovery System på Tunga Fordon

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Kontroll-lokus och beteende i grupp: en studie om sambandet mellan kontroll-lokus och individers beteende i en arbetsgrupp

The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.

Kompetensf?rs?rjning under digital transformation En kvalitativ studie om hur sm? och medelstora managementkonsultbolag i Sverige arbetar med kompetensf?rs?rjning

The aim of this thesis is to analyze how small and medium-sized management consulting firms in Sweden work with human resource management during digital transformation. By interviewing companies, this study explores their approach to attracting, recruiting, and developing competence. The results showed that management consulting firms have good access to candidates, made possible by having a strong corporate culture and attractive working conditions - Crucial parts for attracting talent. Social media and networking are frequently used for marketing and attracting interesting candidates. Digital tools and social media showed to be useful during the recruitment process, but personal contacts and networking still play a central role.

The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Sveriges första flerbostadshus med plusenergiteknik : Köldbryggors inverkan på energianvändningen, en jämförelse mellan plusenergiteknik och konventionellt byggande

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

Klimat för felhantering och Etiskt ledarskap : Felhantering i revision: En undersökning av ett tänkbart samband mellan etiskt ledarskap och felhanteringsklimat.

AbstractFor an audit organization, it is important to work toward maintaininga high error climate to handle errors in an efficient and propermanner. This means that it is important for accountants to worktowards high quality of work, reduce and manage errors that mayoccur in their daily work. Therefore, auditors must know how tohandle errors in order to improve efficiency, which can be affected byhow leadership is exercised in the workplace. The error climatemeans being able to act in a manner which will ensure a good jobtowards customers but also within the internal operations.The ethical leadership may thus have an impact on how auditorshandle the error environment both internally and externally. It is veryimportant for customers to have confidence in the business but also tomaintain the order and the general rules of society for accountingfirms.My study aims to show the thinkable relationship between ethicalleadership and the error climate.

Utvärdering av laddningskoncept för lastbilsbatterier

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

Att återvinna det förgångna: en studie av exploateringsarkeologers informationsbeteenden

The thesis of this work has been to investigate the information behaviour of archaeologists. Interviews were made, between March-September 2002, with ten archaeologists, employed in one Swedish organisation, conducting rescue archaeology. The archaeologists were all experienced in working positions as project leaders. Our thesis could be expressed in following questions: - Which sources of information did the archaeologists use in their work? - Which external and internal factors had influence on the information behaviour? The results of this study have been analysed within a theoretical framework of T.D Wilson, Lars Seldén, Lars Höglund and Olle Persson, among others.

Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Organisationskultur och informationssökning. En fallstudie av internkommunikationen på ett folkbibliotek

This thesis aims to identify bottlenecks in the internal communication of aSwedish public library. Specifically, it addresses the behaviour of the library staff when they seekfor work-oriented information through interaction with their colleagues. A fundamental assumptionof this study is that the information-seeking process depends on organisational culture. I have madean exploratory case study in a medium-sized Swedish public library, where relevant issues areidentified and correlated with the culture of the organisation.I have used Schein's three-level model to describe the culture of the library; this model definesculture as a set of basic assumptions and the actions of people as expressions of their culture. Datafor the study were gathered using several approaches, including interviews with the library staff andobservations of them.

Investeringar i privat och kommunal verksamhet : En studie om faktorer som påverkar investeringar

The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Visualisering av informationskvalitet : Utformning av kvalitetsindikatorer för Lantmäteriets Fastighetsregister

Fastighetsregistret (The Cadastre) is a large and important information sourcesupplied by Lantmäteriet (the Swedish mapping, cadastral and land registrationauthority). Fastighetsregistret provides geographical information about the 3.2 millionestates in use in Sweden. Fastighetsregistret has a large number of users who trustthat the provided data is reliable, but experience shows that the data can have varyingquality. As a user it is not always possible to access more detailed information inorder to assess to what extent the data in Fastighetsregistret is reliable.The purpose of this master's thesis is to investigate the possibilities of a system with agraphical user interface that present, classify and visualize the quality of the data inFastighetsregistret. The defined user group for this suggestion is internal users atLantmäteriet who have a good understanding of Fastighetsregistret.
