Implementation of a Simulated Annealing algorithm for Matlab
In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, an operational transconductance amplifier is simulated. The circuit is modeled with symbolic equations that are derived automatically by a simulator..
Metodval i matematikundervisningen : Hur kan det påverka elevernas förståelse i matematikämnet?
The aim of this study is to examine how students and teachers experience full class lectures in contrast to working individually in mathematics education. Furthermore, the study explores how different ideas of individualization influence the teaching practice.The investigation uses qualitative interviews and the survey analysis is based on the phenomenographic method. The interviews took place in two senior level compulsory schools and both teachers and students were interviewed. The ambition has been to explore the teachers? perspectives regarding their choice of method in the teaching of mathematics.
PIOTROSKIS FUNDAMENTALA SIGNALER;ÄR DE VÄRDERELEVANTA? : EN NUTIDA STUDIE PÅ STOCKHOLMSBÖRSEN
This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.
Framtagande av metoder och rutiner för säkerställande av kompetens : inom miljö, arbetsmiljö och kvalitet
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
Individualisering i undervisningen : Fyra lärares uppfattning om och arbete med individualisering
The purpose of this study is to increase the knowledge of individualism also how individualism is applied in a teacher?s classroom. Based on the curriculum, teaching is tailored to each and every student?s expectations and needs. My research has been qualitative and includes four interviews with practicing teachers in two multi-cultural schools in the city of Stockholm. I have investigated how these four teachers perceive individualism, also how they individualize when teaching to meet all students' expectations and needs according to them.
Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten
In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.
Konflikthantering genom drama : En studie om dramats roll i undervisningen
Abstract The purpose of the essay was to investigate how you can work with conflict management through drama, to promote the meeting with children from many different cultures. I also wanted to see how the work may be different in a heterogeneous or homogeneous group of children.In the background I lift up what a conflict can be, what kind of conflict management methods there are, how to work with drama education as well as what ethnic conflicts can be.The literature studies have shown that there are different types of conflicts and that the conflict management methods are many. In an attempt to get answers to my questions I?ve had drama lessons focusing on conflicts in a heterogeneous and homogeneous group of children in grades 3.My study has shown that conflict management through drama can increase the understanding of other cultures and promote the meeting between children. Just as the literature describes conflicts, they can be difficult to solve and it is important to find a method that suits the class you work with.Key- words: conflict, conflict management, drama, homogeneous, heterogeneous..

Barns smak : En utvärdering av en läsfrämjande-metod baserad på bibliotekariers och lärares erfarenheter
Being able to reflect, evaluate and justify your views is an important part of adult life. Moral education can be a path to develop this knowl-edge; however, it is possible that the moral education gets more obscure when it is not a separate subject. The purpose with this essay is to examine the need of moral education and the presence and the framing of moral education of seven teachers in religion. The purpose is also to analyse where and how the moral education should be included in the curriculum. The survey was conducted through qualitative interviews with a hermeneutic approach.
Project EQS - Elektronisk växelreglering för motorcykel
Husaberg Scandinavia AB is a company producing and developing a range of motorcycles for both on- and off-road use. Husaberg provided the project group with a task of developing an entirely new way of operating the sequential transmission that can be found in today?s motorcycles. The target was to bring the product from idea to a functional prototype ready for further tests. Operation of the motorcycles transmission is today made by a foot pedal placed on the left hand side of the bike.

You should also be able to see how results and the calculation procedure differ between different calculation methods.
Orientalisk institution eller institutionaliserad orientalism? : En arkivvetenskaplig studie av Carolina Redivivas orientaliska handskriftssamling.
This thesis aims to shed light on the collection of Oriental manuscripts at the Uppsala University Library Carolina Rediviva and how the collection is a part of the collective memory. The main question which is central for this thesis is: have orientalism and structures of power influenced the acquisition, arrangement and methods of accessability regarding the Oriental manuscripts? If yes, in what way and why? If no, how has this been avoided?The theoretical framework consists of four approaches: phenomenology, sociology of knowledge, orientalism and power which are applied to the archival concept of collective memory. The main source of material consists of three parts: the historical texts which gives an informational framework regarding the time and place in which the manuscripts were collected, the catalogues in which the manuscripts are described and the transcripted interviews alongside correspondence. Methodologically the thesis is based upon a qualitative method which also partly makes up the foundation for the main material.
