In the reported study, we explored student’s attitudes to a visually androgynous agent in comparison to a male and a female agent in a Teachable Agent (TA) based math game. Each student interacted with two agents, playing the game and chatting with them, and were asked which of the two they preferred (i) as their tutee and (ii) as their conversational partner, and why. Results were that overall th
A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for Cμ was also introduced to account for the better pre
We consider the problem of covering arbitrary polygons with rectangles. The rectangles must lie entirely within the polygon. (This requires that the interior angles of the polygon are all greater than or equal to 90 degrees.) We want to cover the polygon with as few rectangles as possible. This problem has an application in fabricating masks for integrated circuits. In this paper we will describe
Spatially-Coupled LDPC (SC-LDPC) codes have been recently shown to be very efficient for transmissions over nonergodic channels, in particular over block-fading channels [1]. In fact, it is possible to design a SC-LDPC code with any given code diversity [2]. In this work, we investigate the performance of SC-LDPC codes over block-fading channels, assuming a mismatch (or offset) between the first b

Betygsättande lärare utvecklar ofta med tiden en stor kunskap om betygskriterier, i så motto att de får en god känsla för vad i en studentprestation som värderas, bedöms och betygsätts – den så viktiga bedömarkompetensen. Ibland formuleras denna kunskap medvetet och explicit, inför läraren själv, liksom inför berörda studenter och kollegor. Andra gånger stannar den som mer tyst kunskap hos läraren
Rehabilitation of the long-term sick and individuals with a functional incapacity has recently become a burning political dilemma. It is not only a question of the crisis of the welfare state expressed in higher cost for sick absences and early disability pensions, but also an experienced failure of the welfare state to guarantee participation and social rights. The authors of the book discuss fun
The urgent need to be able to make detailed, exact and systematic comparisons which are possible to use in making general statements required not only the development of a methodology, but also methods standardised enough to assure statistical exactness. To achieve a base for detailed comparisons it was essential to combine the information from historical documents and observers´ reports with data

A torus machine is considered to be an advantageous machine configuration that is impossible to produce using traditional laminated core technology. This paper presents a torous machine with the stator winding moulded into a composite core, using the RotoCast technology. The goal of the design and the prototyping is to study the advantages when dealing with a soft magnetic mouldable composite mate
Under april månad i år (1995) var den öppna arbetslösheten bland utomnordiska invandrare 28 procent, medan motsvarande siffra bland svenskar var sju procent. Dessa relativa tal avspeglar invandrarnas respektive svenskarnas svårigheter att anskaffa sysselsättning på arbessmarknaden.
Study of landscape in some early Bergman films. The feneral idea is that Bergman used dramatic settings to enhance the angst of the characters.
