This thesis presents studies of solar wind-magnetosphere coupling using dynamic neural networks in combination with statistically correlative analysis. The primary contribution of the thesis is dynamic neural network models that can be implemented for near real-time predictions of geomagnetic storms from the solar wind alone. With acceptable accuracy, the prediction time has been extended up to 5

Popular Abstract in Swedish Vid radionuklidterapi används ett radioaktivt läkemedel för behandling av vissa sjukdomar, bl.a. struma och vissa tumörsjukdomar. En radionuklidmärkt målspecifik molekyl administreras till patienten och läkemedlet transporteras via blodomloppet till det sjuka området där molekylens egenskaper gör att läkemedlet ansamlas. Den joniserande strålningen som sänds ut från läkRadionuclide therapy (RNT) is a generic term for treatment modalities that use a radionuclide labeled to a target-specific molecule. This so-called radiopharmaceutical accumulates in the target, where the ionizing radiation damages the cells. At sufficient levels of radiation, the cells cannot repair themselves. The quantity of the energy deposited in a target region is referred to as the absorbed

Popular Abstract in Swedish Denna avhandling baserar sig på de erfarenheter av Internet som ett antal människor med betydande kroppsliga funktionsnedsättningar gjort. Personerna i studierna är erfarna och duktiga dator- och Internetanvändare och har få eller inga funktionshinder i dator och online världen, men däremot stora funktionshinder i den fysiska världen. Deras functioning, förmåga attThis thesis is based on the Internet experiences of people with significant mobility/physical impairments who are proficient and experienced computer users in their computer world but have limitations in mobility that severely restrict their functioning in the physical world. The Internet functioning of this group is analysed by means of the factors attitude, control and enabling, with the m

Popular Abstract in Swedish För mer än hundra år sedan visade Hofmeister och Lewith att vissa salter har mer eller mindre förmåga att destabilisera ett protein upplöst i vatten. Ungefär samtidigt, visade Arrhenius att salter upplösta i vatten dissocierar i olika joner. Joner är laddade stabila partiklar som är mycket viktiga för stabiliteten av kemiska och biologiska system. Det har under de senasUsing experiments it is rather easy to measure things on the macroscopic length scale, while it is much harder to measure something in the microscopic world like molecular structure. The opposite is true in theoretical chemistry. It is today rather easy to calculate a bond distance or a coordination number, but it is not possible to perform a calculation aiming at the description of macroscopic ph

The first standards based on thermal manikin measurements were developed in the 1980s. In the Nordic countries tests for thermal insulation measurements of sleeping bags and cold protective clothing were developed. Similar standards were published in Germany by DIN and in the US by ASTM. At a European level, EN 342 describes test methods and requirements for cold protective clothing based on manik

In this paper a dialectic complexity framework is presented and reflected upon. The purpose of the framework is to guide researchers and practitioners in rethinking and reframing underlying assumptions, and address how these have a possible influence and impact on researchers’ and practitioners’ processes of making sense, understanding, explaining, improving etc. aspects of different types of issu

An introduction to the special issue of the European Journal of Migration and Law dealing with undocumented migrants.

Packaging is a fundamental element in logistics systems. It not only affects every logistical activity; it also has a significant impact on logistics costs and performance. In order for packaging and logistics professionals to gain insight into packaging-dependent costs and performance, the interactions between packaging systems and logistics systems must be understood. The presented research prov

During the last ten years or so, much effort has been spent on developing software architecture by analogy with hardware architecture from where the idea seems to originate. Much of the work has been devoted to specifying standard program units, called components, and their connections. The architecture is then the specific organization of these components and connections. In this paper, I suggest

Some preliminary observations on the rise and development of technical terminologies in Greek and Latin, and their successive influence on the modern European languages and their patterns of word formation

We investigate the performance of concatenated coding schemes based on Faster Than Nyquist(FTN) signaling over the AWGN channel. We test both serial and parallel concatenations. In serial concatenation the FTN signaling is considered as the inner encoder and the outer code is a rate b/c convolutional code. In parallel schemes we use two parallel Gaussian channels and transmit FTN pulse trains in b
