In group work roles play a role. (Swedish: Vid grupparbete spelar rollerna roll) In Handbook for group work – how to form functioning group work in education (Swedish: Handbok för grupparbete – att skapa fungerande grupparbeten i undervisning) Types and functions of roles in work groups are presented in overview followed by a discussion of relations between roles, personality and team roles. Role

Emergent behaviour has become a plague of automation systems based on communication networks. Centralized monitoring of the network comes generally to late to sup-press unwanted behaviour. It is required to mark the ten-dency towards state changes in a decentralized manner. The paper discusses the role of local awareness by inspection of the model learning behaviour of feed-forward networks. The c

Purpose of this paper The purpose of this paper is to investigate the effects of using the smart goods on traceability information and consequently on the carried out activities for different actors of the fresh food supply chains. Identification of the valuable traceability information types in fresh food supply chains is conducted as the first step to reach the purpose. Design/methodology/approa

The author sets out to analyse a number of representations of the biblical Hagar figure in African American and white American culture. Spivak (1988) has problematized the marginalization concept with regard to the study of the third world subject, arguing that knowledge always expresses the interests of the knowledge producers, and that Western academic research is always colonial. The aim of the

Popular Abstract in Swedish Magnetresonanstomografi med faskontrast (PC-MRI) är en icke-invasiv metod för att mäta hastigheter och blodflöden i kroppens större blodkärl, och är ett viktigt verktyg för att diagnosticera och avbilda onormala fysiologiska förlopp. Under de senaste två årtiondena har PC-MRI utvecklats från hastighetsmätningar i enskilda riktningar och snitt till avbildning av komplettIn the last two decades, phase-contrast magnetic resonance imaging (PC-MRI) has evolved from two-dimensional velocity and flow measurements to volumetric, time-resolved depictions of velocity fields (4D PC). The acquisition of time-resolved velocity fields allows flow visualisations that might provide better understanding of the dynamics of the cardiac system. Because 4D PC is increasingly being u

This paper focus on quality indicators for lifelong learning and the learners’ choices. The main issue for the paper is indeed to highlight the Swedish response to some of the initiatives from the Commission concerning LLL and the eAction plan. The paper will also give a short overview, mainly of the Swedish Net University.

Due to increasing oil demand and serious global warming, a green power generation system is urgently requested in transportation. Electric/hybrid vehicles (EV/HEV) have been considered as a potential solution with great promise in achieving high energy/power efficiency and a low environmental impact. The important electric and electronic equipment in EV/HEV are the battery, inverter and motor. How

We discuss some results in coding and decoding for multiple-access channels. A new approach to choosing codes and users' energies for that channel is described. For the case when a bit error probability and a decoding complexity are fixed we construct a region of achievable code rates.

Since the Internet is developing rapidly in size and in complexity as well, it is very hard to adjust quality of service (QoS) parameters. In order to guarantee service quality, efficient resource reservation is needed. The allocation of resources requires a dynamic reconfiguration mechanism that configures a switch, taking into account the incoming traffic fluctuations. This paper presents a new

This publication is designed to provide accurate and authoritative information in regard to the statics in structural engineering. "STATICS FOR CIVIL ENGINEERS" is made up of 7 chapters, concentrating on the main and most important fields of the subject matter covered and presenting a wide variety of examples and exercises. Some related parts with less necessity for the students or experts of stru

The aim of the thesis is to study the change in the Scanian rural society and landscape during the time of the radical enclosure reform "Enskifte" (Sw.) in the early 19th century and the decades therafter up until c 1850. Seven parishes on the southern plain of the province of Scania are studied in more detail, while the province itself is the study area in two of the nine chapters. The theoretica

In the inversion in R 2 of the exponential Radon transform, a scalar function f is found from its integrals, with exponential weight functions, over lines. In this paper we demonstrate how to define two different kinds of exponential Radon transforms for vector fields in R 2 in a natural way. It is shown that having data from these exponential vectorial Radon transforms it is possible to reconstru
