Matematik i förskolan : Hur arbetar pedagoger med matematik utomhus på förskolor med olika pedagogiska inriktningar (traditionell, i ur och skur och Reggio Emilia)?
In this essay, I have interviewed four pedagogues from three preschools whit different pedagogical purposes. The purpose was to find out how they work with mathematics outdoor. In addition to interviews, I have conducted observations at each preschool. The different preschools are one traditional, one Reggio Emilia and one ?all weather? (Friluftsfrämjandet) preschool.
Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica
Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
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). An
improvement is only seen when the BER becomes much lower than what is common in
real situations.
In conclusion DDCE is complicated, involves many mathematical operations and
gives insignificant improvement of SNR when BER takes common values. It is
legitimate to question if it is possible to use the method in a real mobile
phone system..
Prefabricerat trähusbyggande med moduler : För- och nackdelar samt förslag på vidareutveckling
The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..
Förståelse för och attityder till matematik
Studiens syfte är dels att undersöka vilken förståelse för matematik ur ett samhällsperspektiv som elever på en mellansvensk kommunal gymnasieskola har, utifrån den beskrivning av ämnet som finns i de svenska styrdokumenten. Syftet är också att undersöka vilken inställning till ämnet eleverna har, hur attityden påverkas av vänner och familj, samt vilken betydelse media har i synen på matematik.Studien bygger på en enkätundersökning där 130 respondenters svar har behandlats. Genomgående i analysen har gruppen med elever som läser ett yrkesinriktat program jämförts med de elever som studerar på ett mer teoretiskt inriktat program.Resulatet visar att elevernas förståelse för matematikens roll i samhället är fullt acceptabel, men att det är få som nått ett fördjuad insikt. En klar majoritet anser att de förstår syftet med matematikundervisningen.Trots att en dryg trejedel tycker att matematik är det viktigaste ämnet så finner cirka hälften inget intresse för ämnet. En sjundedel säger sig t.o.m.
Undersökning av ackommodationsförmåga och brytningsfel hos varmblodiga travare :
Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses.
Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months.
In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.
Kära dagbok. Hur går det till när man tar guld? : Innehållsanalys av Spendrups reklamkampanj
This is a case study of the advertising campaign ?Guld till alla? (Gold to Everyone) embarked upon by Spendrups Bryggeri AB in a bid to promote Norrlands Guld, during the period 2004. The approach used by Spendrups will be compared with theories about communication planning, communication strategies, target group definition and how to create effective advertising. The main purpose of the comparison is to find which central elements that made the campaign successful. The method we have chosen to use is an explanative content analysis with influences from the dialogue analyse.?Guld till alla? was suppose to be an massive and coherent campaign which was to be integrated with large sports events, such as the Ice Hockey World Championship, UEFA European Championship and the Summer Olympic Games, that all took place the year 2004.
Att undervisa i matematik med fokus på elever med annat modersmål
AbstractThe purpose of this investigation was to understand how teachers/pedagogues nowadays work with mathematics in school. In what way can they pin point the difficulties a pupil with another language might have with mathematics.I started the process of this investigation by reading litterature on the subject. Then I did interviews with several teachers and pedagogues teaching in different schools with children at different ages.The results found in my investegation pointed to a lack of practical work with mathematics especially in classroom and revealed from the teachers a strong desire to work with mathematics in different ways.?Talking maths? with pupils in class will help them understand the subject better. Several teachers are of the opinion that the pupils will reach the goals in school with this method.The teachers are also aware of the importance of having practical mathematics.
Skolans underskattade språk : En studie om användningen av det matematiska symbolspråket i den gymnasiala undervisningen
Symboler har alltid varit en viktig del av matematik, därför är det inte konstigt att kunskaperom symbolspråket behövs för att uppnå en full förståelse av ämnet. Den här studiensyftar därför på att utreda användningen av det symboliska språket i den svenska gymnasialaundervisningen ur ett språkvetenskapligt perspektiv. Empirin till det här arbetetbestår av 52 elevlösningar till ett test i matematik samt transkribering av en parintervju.Det insamlade materialet har analyserats utifrån teorier om den metalingvistiska medvetenhetensamt symbolernas semiotiska och epistemologiska funktioner. Det matematiskasymbolspråkets roll i styrdokumenten har också belysts i det här arbetet. Från elevernasfel i testet var det möjligt att åskådliggöra vikten av den metalingvistiska medvetenhetenoch den semiotiska medlingen i algebrainlärningen.
Landskapsplan för Tosthult : en småskalig studie och skötselplan
The aim of this dissertation is the production of a landscape management document to protect and improve elements of biological, cultural and economic value found within the site at Tosthult. The study involves both analysis of the current grazing regime, comparison of today?s flora with flora collected in the fifties and a SWOT analysis of inhabitants? views on Tosthult?s landscape and neighbourhood. The resultant landscape management document applies to an area over 134 ha and is valid for thirty years. The proposal contains 26 separate management units, each with necessary information on the area, definition of management goals and the mix of management procedures to undertake.
?... eftersom det brukar vara lättare att lyssna på lärare än boken? : Elevers och lärares tankar om den interaktiva skrivtavlan i matematikundervisningen
The purpose of this study was to explore students' and teachers' experiences of the new pedagogical teaching tool, interactive whiteboard, which have gained increased popularity and wide spread usage in the classrooms. An observation during a mathematical lecture was conducted as a pilot study prior to the main research method of phenomenology; based on students? self-descriptions and interviews with two teachers, this methodological approach was used to investigate the subject matter. The interpretation, comparison and analysis of the results surrounding this new teaching method is explained by two theories, constructivism and socio-cultural perspective. The information shared by the students and teachers have been broken down into four categories: enjoyment & interest, practical, insight and no different.
En grundläggande modell för att beskriva stadens ljudbild med utgångspunkt i dess rytm
The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.
Rött, vitt, svart - Vedisk kosmologi och klassificering i Ch?ndogya-Upani?ad 3:1-11 och 6
Chapter 6 of the Ch?ndogya Upani?ad has often been treated in works on early Indian philosophy, as well as in some comparative studies on color symbolism. Attempts to place it in a larger framework against the background of late Vedic religion are, however, few, the rationalistic and ?tradition-challenging? appearance of the text having repeatedly been emphasized. But the doctrine contained in the text ? a cosmologic teaching on the three elements constituting the universe, each being characterized by a color (red, white, black) ? and their microcosmic counterparts in the human body, does have some clear affinities to the worldview of the Br?hma?as and ?ra?yakas, which posits a series of similar correlations (bandhu-) between macro- and microcosmos.

The brother has been living a hectic life of drug addiction. The relationship between brother and sister is characterized by ironic distance, but also a lot of love.
Att identifiera signaler för obestånd i tid
To be able to protect themselves from credit risk, the banks must constantly check the performance of the companies they have lent money to. There are many mathematical models for predicting financial distress. These models use accounting-based ratios, which often are historical and not representative for the present situation. This study describes how the banks do in practice to find signals of insolvency in time and the variables they are observing for doing that.In addition to financial reports which the company sends in to the bank at least once a year, also the relationship between them and information from different information agencies are of great importance to track signals of insolvency. Poor profitability is the primary cause of insolvency.
