Micro mobility and internet access performance in Ad Hoc networks

In ad hoc mobile networks nodes typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper evaluates a solution that allows mobile nodes to access the wired Internet and roam from base station to base station. The solution is based on the extension of Mobile IP capabilities to t

Challenging gender stereotypes using virtual pedagogical characters

The paper explores motivational and cognitive effects of more neutral or androgynous-looking characters versus more feminine-looking female and masculine-looking male characters. A user study involving 158 students, aged 17-19, encountering four virtual characters, visually manipulated to represent gender stereotypicality versus androgyny, is presented. On the one hand we explored students’ attitu

Culture Unbound: Americanization and Everyday Life in Sweden

This book investigates the significance processes of Americanization have had in shaping and influencing the form and content of everyday life in Sweden. However, rather than simply viewing Americanization as an irresistible homogenizing force, it is argued that to the extent that Swedish everyday life has been Americanized, it has been Americanized in a very Swedish way. Here the dreams, actions,

”Historia à la Hollywood – Steven Spielberg i pulpeten”

A text that sees the American film director Steven Spielberg as an audiovisual lecturer of history. In the analysis how Saving Private Ryan depicts the past, aesthetic and technical considerations are dealt with at the same time as more general and historiographic topics are problematized.

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

A pharmacodynamic study of 5-azacytidine in the P39 cell line

OBJECTIVE: 5-azacytidine (azacytidine), a DNA hypomethylating agent, was recently approved as the first therapeutic agent for the treatment of myelodysplastic syndromes. The present subcutaneous dosing schedule, 75 mg/m(2) for 7/28 days, is based on early clinical studies and may constitute a practical problem for patients. The present in vitro study aimed at evaluating the pharmacodynamics of aza
