In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.

This paper gives an introduction to the theory of minimal surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal surface and giving a brief histo- rical survey, we look at some well-known minimal surfaces and a few of their characteristic properties. The connection between minimal surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .

The number of wireless networks has increased rapidly among both home users and companies in just a few years. That has brought a lot of good things with it, for example the possibility to connect wireless equipment to the network or Internet from an arbitrary position within range of the accesspoint. But since the transmissions take place through the air some new security risks appear. It?s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network.

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.

This master thesis starts in a wondering about the visions and ideas we have about thecity and about the urban. In Swedish about the term stadsmässighet, which can be translatedin to city-like, urban or urbanely, something that describes or contains features ofthe city. How do we use the city as a role model? Is urbane building the same as buildinga city? Is it about architecture and aesthetics or is building urbanely the way to makepopular cities? The central aim of this essay is to study visions and reality around urbanebuilding in order to understand the concept?s meaning and how it changes. My ambitionis that the essay will function as a discussion basis for students and planners.The work starts with literature studies where theoretical definitions and concepts aboutcities and about the urbane is investigated.

Uppsatsen är ett resultat av en explorativ studie som undersöker projektledarens uppfattning av interaktionsdesign ur ett resursperspektiv. Detta görs genom en kvalitativ undersökning med projektledare för systemutvecklingsprojekt. Utifrån vilka det gjordes en nulägesrapport om hur vida resurserna som läggs på interaktionsdesign är adekvata. För att få en ytterligare aspekt på behovet intervjuades även en interaktionsdesignskonsult. Studiens resultat visade att det skiljer sig mellan olika typer av projekt hur vidare tillräckligt med resurser läggs ner på interaktionsdesign.

Arbetets art: Examensarbete i lärarutbildningen, Avancerad nivå, 15 hp Högskolan i SkövdeTitel: Matematik är något som man har och gör i skolanEn studie om hur sex elever i årskurs fyra uppfattar matematik och sin matematikundervisningSidantal: 39Författare: Anna Gustavsson och Helen NordqvistHandledare: Susanna Nilsson JacobssonDatum: Januari 2008Nyckelord: matematik, matematikundervisning, uppfattningar, inställningar,lärandeSyftet med studien var att undersöka hur elever uppfattar matematik och sin matematikundervisning samt vad som ligger till grund för deras uppfattningar. En nyfikenhet kring hur elever tänker om matematik och dess användningsområden har också genomsyrat studien. Tanken var att fördjupa kunskaperna och förståelsen kring hur elever kan uppfatta matematik och matematikundervisning för att sedan ha användning för detta i vårt kommande yrkesliv som pedagoger. Vi anser det viktigt att vi som lärare blir medvetna om elevernas uppfattningar, då flera undersökningar visar en nedåtgående trend i elevers intresse för matematik vilket också kan påverka deras prestationer. För att undersöka elevernas uppfattningar valde vi att använda oss av kvalitativa intervjuer, vilka genomfördes på en skola i Västra Götalands län med sex elever från årskurs fyra.

This essay focuses on tourists' information seeking. The main focus was to examine whether there is a connection between how the informants in different tourist styles the different tourist styles are presented by Eva Wolf as the tourist of recreation, action, culture, compromise, and individualism seek information to their forthcoming vacation. The result was reached through a qualitative method, where ten informants with various tourist roles were interviewed separately. The informants were chosen by personal contacts. In addition to these interviews, three representatives from the tourist industry were contacted and interviewed by e-mail.

Background: An increasing number of operations on children are performed as day surgery and this experience of health care may affect future hospital stays. The aim of this qualitative study was to describe children´s experiences in connection with day surgery. Method: Ten children aged six to fifteen who had gone through general anesthesia at examinations or surgery were interviewed and the content was analyzed by systematic text condensation. Result: The core category ?From uncertainty to relief with newly acquired experience? could summarize the result of this interview study.

Syftet med detta arbete är att ta reda på om läxor ger fördjupad kunskap inom ett ämne. Vidare vill vi veta vad syftet med läxor är. Vi har genomfört femton intervjuer, jämt fördelade mellan lärare, elever och föräldrar. Resultatet pekar på att läxor behövs, men att eleverna vill ha en annan typ av hemuppgifter än de i nuläget har. Vi genomförde även mindre studie på sex av våra egna barn för att få veta hur mycket tid de trodde sig lägga på sina läxor och hur lång tid de i verkligheten ägnade åt läxläsning. Vår slutsats är att om läxor ges, ska de vara väl genomtänkta och att det kan skapas utrymme för att göra läxorna under skoldagen. Nyckelord: läxor, kreativitet, individ, variation.

Syftet med uppsatsen var att bidra med kunskap om hur Use Cases kan användas och omdet fanns en möjlighet att återanvända dem. Use Cases är ett av de mest användaverktygen för modellering, de beskriver en sekvens av en händelse som inskaffar ettmätbart värde. Use Cases fångar funktionaliteten i olika situationer. Vår studie varkoncentrerad på skillnaden mellan Use Cases så som vi uppfattat Rational UnifiedProcess (RUP) modell jämfört med Telecas återanvändbara Use Cases. Undersökningengjordes på telekomföretaget Teleca.

The purpose of the study is to examine how teachers and students believe that graphing calculators affect the teaching of high school mathematics courses. By becoming aware of this, teachers and teacher students have the opportunity to reflect on the use of graphing calculators in their teaching. The empirical base consists of interviews with teachers and a survey among students at two high schools in southern Sweden. The results show that teachers especially consider the graphing calculator as a tool, much like paper and pencil. They use it if and when it is deemed able to contribute in a significant way in their teaching, either to save time and/or to help deepen the understanding of various mathematical concepts and methods.
