The creative world of middle childhood : Creativity, imagination, and self-image from qualitative and quantitative perspectives

Popular Abstract in Swedish Inledning Kreativitet kan definieras på många olika sätt. I denna avhandling definieras kreativitet som ”ett generativt eller produktivt nytt sätt att uppleva verkligheten och sig själv på”, vilket är en något modifierad version av Smith och Carlssons (1990) kreativitetsdefinition. Det produktiva sättet att se på verkligheten uppkommer just av att man kan rekonstruera Four studies on creativity, imagination and self-image in 10-year-old children constitute the basis of this dissertation. A total of 179 participants were involved. Study I investigated two new creativity measurements comprising The Drawing Task, which had its starting-point in a brief story, and The Activity Questionnaire, which included questions about the children’s spare time activities. The h

Source Localization Using Virtual Antenna Arrays

Using antenna arrays for direction of arrival (DoA) estimation and source localization is a well-researched topic. In this paper, we analyze virtual antenna arrays for DoA estimation where the antenna array geometry is acquired using data from a low-cost inertial measurement unit (IMU). Performance evaluation of an unaided inertial navigation system with respect to individual IMU sensor noise para

Modular three-phase machines with laminated winding for hybrid vehicle application

A design model development for electrical machines with laminated windings is presented. The focus is to provide manufacturable solutions for commercial vehicle traction applications. The machine is designed with axially distributed single-layer wave-winding segments with a core that builds a modular three-phase machine. The phase segment, whose central part is a wave-winding made as a laminated w

NMR Self-Diffusion Studies and Stability Studies of Emulsions

The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. We have investigated what characteristics of emulsions that the NMR self-diffusion technique can shed light on. The diffusion behavior of the liquid inside th

Propagation aspects of vehicle-to-vehicle communications - an overview

Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety, congestion avoidance, etc., but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. This paper provides an overview of existing VTV channel measurement campaigns, describing the most important environments, and the delay spread

Experimentation in Software Engineering: An Introduction

The purpose of Experimentation in Software Engineering: An Introduction is to introduce students, teachers, researchers, and practitioners to experimentation and experimental evaluation with a focus on software engineering. The objective is, in particular, to provide guidelines for performing experiments evaluating methods, techniques and tools in software engineering. The introduction is provided

CFD Modeling Considering Different Kinetic Models for Internal Reforming Reactions in an Anode-Supported SOFC

Fuel cells are electrochemical devices that transform chemical energy into electricity. Solid oxide fuel cells (SOFCs) are particularly interesting because they can handle the reforming of hydrocarbon fuels directly within the cell. This is possible due to their high operating temperature. The purpose of this study is to develop an anode-supported SOFC model, to enhance the understanding of the in

LTE Over Copper - Potential and Limitations

The densification of mobile networks in order to meet increased capacity demands is ongoing, needed and costly. A few papers have been published based on the insight that the fixed broadband networks offer a multitude of sites, for instance our homes, for potential small cell deployment providing backhaul capacity and power without site costs. However, in order to reach economical large-scale bene

Gränser som förenar – ett grundmotiv i postjugoslavisk film

Texten tar upp gränsmotivet i jugoslavisk film, framför allt genom att lyfta fram två filmer, Innan regnet faller (Pred Dozhdot, Mancevski, 1994) och Ingenmansland (Nicija zemlja, Tanovic, 2001). Dessutom diskuteras begrepp som jugoslavisk och postjugoslavisk film.
