Identifiering av synkronmaskinsmodell genom SSFR-test

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

Vilka är egentligen i behov av särskilt stöd? : En undersökning om lärares åsikter om arbetet med åtgärdsprogram i ämnet Idrott och hälsa

The purpose of this study was to examine how teachers see the use of action plans for students in need of special support in physical education. The questions used were: What do the teachers consider being the causes for students not reaching the objectives in physical education? What experiences do four teachers have considering the work with action plans for students in need of special support? And, what experiences have one chosen head of school about establishing action plans for students in need of special support?To reach the answers to these questions qualitative interviews were made with four teachers from different schools. The interviews deal with the teachers views on assessment, curriculum, and the work with action plans for students in need of special support.The results show that that the underlying causes for students not reaching their objectives was either lack of participation or difficulties in certain parts of the subject. Despite this, the teachers write very few action plans even though it appears there are students in need of special support.

Boendepedagog: strävan från yrke till profession : En kvalitativ studie om implementeringen av boendepedagogik

The aim of the study was to look at a particular work group of housing supporters, whomhave implemented two special working methods in their work. The methods have been implemented by two of the housing supporters that also have special education in the methodsSOC (Sense of Coherence) and solution focused brief therapy. The study is based on anethnographic observation and analysis of documents that are used in the implementation. To analyse the information that was given at the observation and in the document I´ve used a theory which illustrates the significance of developing professions so their knowledge become legitimate. I´ve also used a theory that illustrates the importance of implementation and how it´s done at its best.

Elevanpassad undervisning : En studie om gymnasieelevernas perspektiv på lärande i naturvetenskapliga ämnen  

The purpose of my study is to determine students? attitudes to the Natural Science subject. I want to contribute to scientific discourse about different learning styles that can respond to childrens? requirements in teaching as well as to determine the student?s experience of learning styles. The studies were carried out at an upper secondary school in Stockholm (spring term 2011) for three different classes.

Kulturbegreppet i skapandet av nya medborgare : En uppsats om integrationsprocesser och diskurser i det sena 1900-talets Sverige

In this thesis the author has through a discourse analysis examined how the concept of culture has been used in the discourse of integration during the late twentieth century in Sweden. The author argues that the integration of immigrating people has been the fundamental method in creating Swedish citizens within the immigrant communities. In this discourse the concept ?culture? has been a constant recurring way of explaining differences among the immigrants towards ?ethnic swedes? and Swedish way of life and establishing difficulties in performing integration outside of governmental policies. When looked upon in terms of discourse the integration process is the possibilities, intents and interests and the actual creation i.e.

Hur tänker elever? : Elevintervjuer som metod för att kartlägga elevers tankar kring matematikundervisning

During my time as a student of education I have learnt that it is my responsibility, as a teacher, to adjust the ways in which I teach to the needs, abilities, experiences, and thoughts of each individual child. What I have not yet gained much knowledge on is how to go about finding the children?s thoughts.In this thesis I investigate the interview as a method of finding out how sixth graders think about their mathematics education. Four children were interviewed. In addition to these inter-views, as a means of giving a broader perspective to and a greater understanding of the chil-dren?s answers, one math lesson was filmed and the math teacher was interview on two sepa-rate occasions.What I found was that a number of factors seemed to influence the children?s thoughts and answers, and that their answers were most likely not always a mirror of their thoughts.

Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Kan du bevisa det? : En enkätstudie av gymnasielärarens förhållningssätt till matematiska bevis

Practice of mathematical proof increase the understanding of mathematics anddevelop creativity skills, problem solving, communication, logical thinking andreasoning which are all important tools not only within the subject of mathematicsbut also important tools for the society in which we are living. The aim of this projectwas to investigate whether it is accurate that proof and proving has a subordinate rolein mathematic education in the upper secondary school in Sweden. This was done byconstructing of a digital survey that was sent to approximately 100 practicingmathematics teachers in a normal size city located in the middle of Sweden. Theresults of the survey show that the teachers consider themselves comfortable withtheir own skills in teaching proof. Paradoxically, the results also show that there is alack of teaching of proof and proving in the upper secondary school, although the newcurriculum puts more focus on proof and proving..

Nybörjares svårigheter vid tillämpning av designmönster

Designmönster inkluderas ofta i utbildningar inom objektorienterad programmering vid högre lärosäten. Det finns dock flera studier som indikerar att det kan vara svårt för nybörjare att förstå hur de ska tillämpas. M. Abdul Jalil och S. A.

AbstractSweden has over the past years grown into a multicultural society which has caused that people with numerous variances of religion and cultures have to interact. This essay will be based on several primary school teacher?s experiences with immigrant families. The purpose of this essay is finding out how they are introduced and integrated in Swedish primary schools by the teachers.I?ve interviewed six primary teachers that shared what they?ve experienced with immigrant families.

Att främja barns delaktighet: En studie av barnbibliotekariers syn på barns delaktighet i folkbibliotekets barnverksamheter

The objective of this thesis is to explore the prerequisites for children?s participation in the activities of the public library as expressed by six children?s librarians. Qualitative semi-structured interviews were carried out to investigate how the librarians interpreted the concept of participation and viewed power issues between children and adults. Further, difficulties and possibilities experienced in working with children?s participation and manifestations of children?s participation in everyday library work were also investigated.

Hur löser elever med kombinerade läs-, skriv- och matematiksvårigheter matematiska problem?

Syftet med denna studie är att ge en insikt i hur elever med kombinerade läs- och skriv och matematiksvårigheter tänker och resonerar vid problemlösning.Tre elever i år 8, som alla ingår i samma specialundervisningsgrupp i matematik, har arbetat med olika typer av matematisk problemlösning, såväl individuellt som i grupp. Med utgångspunkt i deras arbete skapas början till en grundad teori.I forskningssammanhang behandlas ofta denna kategori elever (med kombinerade problem) som en enhetlig kategori som jämförs med t ex elever med enbart matematiksvårigheter, normalpresterande elever osv. Denna undersökning visar dock att de svårigheter eleverna uppvisar är av mycket olika karaktär.Studien omfattar tre delar: en presentation av fältstudien och resultaten från denna, en metoddel innefattande en pilotstudie som koncentreras på datainsamlingsmetoden samt en omfattande litteraturstudie som behandlar problemlösning och inlärningssvårigheter..
