Förbättrad resistansmätning för grova aluminiumledare
The goal with this master thesis has been to evaluate and to examine the stationary resistance bridge. The resistance bridge uses a 4-point measuring to determinate the resistance, which is used in the manufacturing of the Conductor. It is then used when the resistance is to be decided for coarser aluminium Conductors. A Conductor has to fulfil certain demands to be able to move forward in the process. One of these demands is the resistance in ohm/km, which has demands that the measure values of the resistance bridge are as true and precise as possible.

Conductor. It is then used when the resistance is to be decided for coarser
aluminium Conductors. A Conductor has to fulfil certain demands to be able to
move forward in the process. One of these demands is the resistance in ohm/km,
which has demands that the measure values of the resistance bridge are as true
and precise as possible.
The stationary resistance bridge had been examined through various kinds of
measurements to be able to see how stable the system is and how to obtain a
measure value as optimized as possible.
Analys av fördelningssystem för bostadshus
The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated. The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN Conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN Conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN Conductor loss is obtained.
Att sjunga i damkör : En studie om damkör som social och musikalisk företeelse med fokus på Uppsalakören La Cappella
This essay discusses sentiments underlying choices to sing in women's choir. The focus is on the female choir La Cappella from Uppsala, which is run at a professional level to constitute one of the premier choirs in the country. The La Cappella members and their Conductor participated in a survey with questions about how they view their own role as a singer or Conductor in a choir. The questions that this paper is based on are the following: Why choose to sing in the choir? How do the Community and the social network between women affect their decision to sing in a women´s choir? Has the sound of the chorus played an important role in the choice of choir? Interwoven in the text, I discuss and compare La Cappella with choir Flora, a Finnish-Swedish women's choir..
Från digitalt till analogt : En kvalitativ studie av överföringsprocesserna från MIDI till notskrift i symfonisk musik
This study examines how to translate digitally composed symphonic music to note script and how it gets readable and playable. With the help of professional musicians from the Norrköping Symphony Orchestra, teachers from Kulturskolan in Norrköping as well as other musicians, I have learned how I can improve each individual stem in my composition. I also learned how to write for a real musician. My score have been analyzed by composers and a Conductor which have given me a more in depth insight into composing symphonic music.The theory section describes important MIDI aspects, score preparation and note editing techniques. Thereafter is a section about the symphony orchestra and its instruments? history and how the situation is today.

Subjektiva och objektiva jämförelser mellan två benledningshållare, Softband och Adjoin
Background: Bone anchored hearing system is a surgically implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone Conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone Conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..
Utvecklingssamtal - utifrån elevens perspektiv
My aim with this diploma work is to find out if the students consider development deliberations as a good forum in order to promote their knowledge development or not. I have also examined if the development deliberation is experienced as giving for the pupil or not, what I have been studying from the pupil's perspectives.MethodI have implemented three qualitative interviews with three students from class nine in a compulsory education that lies in Botkyrka municipality. There, I have also an implemented questionnaire survey with two half classes from same class.Materials To my study I have linked literature where research aims himself in on how teachers have worked with development deliberations in the school.Results Students that I have interviewed does consider development deliberations as a knowledgep romoting forum, but most as a forum for clear about study results. The students in the survey consider development deliberations as giving only when the result turns out to bee good.Importance for teachers As each development deliberation is unique, you can not come to a certain implication that all deliberations are experienced in the same way as the result shows. But that can last stakeholder for the teacher is to see how one development deliberation can to be experienced of several students.
Kollektivt Musicerande
The purpose of this master thesis is to identify some phenomena that may contribute or work against the individual musician?s opportunities to contribute with their personal musical intuition in the orchestral work. I want to investigate under which conditions and in what context the orchestra environment gives musicians opportunities to take musical initiatives. I will also test a method to develop and work with musical intuition in a staged trombone audition called blåst. My wish is to highlight orchestra musician's perspective and experiences and to discuss where in an orchestral musician?s everyday work the artistic and authentic musical initiative appears and how we are going about it.
Imitation som intervention : En behandlingsstudie om hur Intensiv Imitation påverkar samspel och kommunikation hos en flicka med Rett syndrom
Rett syndrome is a congenital neurological syndrome, which in the classic phenotype only affects girls. The symptoms include lack of speech, stereotypic movements of hands, dyspraxia and mental retardation, and these symptoms lead to communicative impairments. The purpose of this study was to examine whether the intervention method Intensive Imitation affected interaction/communication and initiative in a girl with Rett syndrome. The design of the study was a Single Subject Experimental Design with a three-week long intervention period where the girl participated daily in 30- minute sessions of Intensive Imitation together with the test Conductor. Interaction, communication and initiatives were observed and analyzed before (Baseline A), during and after (Baseline B) the intervention period.

Konstruktion av värmespridare med grafit för flygelektronik
This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalConductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.
