Modellera i 3D med Tekla Structures. Ett konstruktionsprogram anpassat för BIM

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Ungdomars informationssökning på Internet : Vad ungdomar tycker om sina egna kompetenser och erfarenheter

The study aims to investigate student?s attitudes and experiences of information retrieval on the Internet, as tools for learning. I have been interested of their own views about their own knowledge and experience in the subject, information seeking on the Internet. The focus is on what they perceive as problematic, what skills they consider they have and what needs they have in terms of teaching. Data were collected via questionnaires.

Det livliga barnet eller den stillasittande eleven? : En kvalitativ undersökning om barns rörelsebehov i klassrummet

The purpose of my empirical study is to see if and how teachers meet the students needs of physical activities in the daily work in the classroom. I also want to explore how different teachers see the connection between the concepts: physical activity and learning. To fulfill the purpose, I have chosen to ask four questions that I will work on in my study.How much and what type of physical activities do the students do in a typical day at school?What happens with the students when they have had a moment of physical activities in the classroom?Do the teachers see any connection between the physical activity and the pupils' ability to concentrate?How do teachers look upon the relationship between physical activity and learning?To get answers to my questions, I have observed and interviewed five teachers. I have compiled and analyzed the results.

Återladdning av borrhål i Borås Djurpark. En studie om möjligheter att kombinera solfångare med ett befintligt bergvärmesystem

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

"Lillapan finner en vän" : Barns delaktighet i lässtunden

The purpose of this study has been to describe and analyze how seven Swedish preschool teachers and two special education teachers think and work with children who show a lack of social skills. The study method has been semi-structured interviews with the educators which have been analyzed and sorted under different themes/categories. The theoretical framework used in this study is sociocultural, relational and categorical perspectives. These perspectives have been chosen in order to better understand how teachers see their role in supporting children in need of special support. The environment in the preschool is found to be of great help and the teachers? approach is of great importance.The research emphasizes the importance of integrating thinking, feeling and behavior.

Grammatiken i praktiken : Om gymnasieelevers förmåga att tillämpa grammatiska kunskaper i muntlig kommunikation

This paper sets out to examine to what extent French grammar teaching contributes to the students? practical, oral skills. Are the students familiar with the grammatical system without knowing how to apply it orally in practice? The paper contains a theoretical background and an empirical survey. One quantitative and one qualitative method have been applied in the survey.

Fysisk aktivitet, motorik och lärande- några förskollärares erfarenheter och förhållningssätt

Syftet med vår studie var att ge ett kunskapsbidrag till problemområdet motorik, utveckling och lärande med utgångspunkt från några pedagogers arbete med och förhållningssätt till fysiska aktiviteter och lärande i förskolan. Vi valde att genomföra en kvalitativ studie, där vi intervjuade sex verksamma förskollärare. Tidigare forskning har delade meningar om fysisk aktivitet och dess betydelse för barns lärande. Flera forskare konstaterar dock att det finns ett samband mellan motorik och lärande. Resultatet av studien visade att också verksamma pedagoger ser ett samband mellan motorik och lärande.

Transportsfordon för rullstolsburna

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.
