The Great East Japan earthquake and tsunami hit coastal cities in Iwate, Miyagi and Fukushima Prefectures of Tohoku Region devastating the energy supply system in the region. Electricity and fuel shortages caused severe problems in the city of Kamaishi varying from lack of mobility, communication, heating to reduced health conditions. This paper, aims to analyze the impacts of the earthquake and t
The preparation of donor (D)-photosensitizer (S) arrays, consisting of a manganese complex as D and a ruthenium tris(bipyridyl) complex as S has been pursued. Two new ruthenium complexes containing coordinating sites for one (2a) and two manganese ions (3a) were prepared in order to provide models for the donor side of photosystem II in green plants. The manganese coordinating site consists of bri
Description: Python® is a free open-source language and environment that has great potential in scientific computing. Computing with Python presents the programming language in close connection wit mathematical applications. The approach of the book is concept based rather than a systematic introduction to the language. It is written for a mathematical readership and is aimed at students with a ma
Popular Abstract in Swedish Många fåglar flyttar regelbundet långa sträckor mellan sina häckningsplatser och vinterkvarter. På rastningsplatser längs flyttningsvägen stannar fåglarna upp och äter, för att lagra upp de energi-lager de behöver som bränsle när de flyger. Vissa flyttfåglar lägger på sig så mycket bränsle (energi), mestadels som fett, att de dubblar sin kroppsvikt. Det lagrade bränsletBirds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. To minimise the total time spent on migration, birds should fuel up a

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
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
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,
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.
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
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
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
