Origins and resolutions in Financial Crises; A Policy Dilemma

The latest insights on financial contagion and how both nations and investors can effectively deal with it The domino-style structure in which the financial system exists is a perilous one. Although historically, the financial system has been able to deal with major shocks, the fact remains that our financial system is not as secure as it should be. Recent years have brought about too many exam

Ultrafast, jitter-free x-ray streak camera that uses single-photon counting

A novel method developed to increase the temporal resolution of x-ray streak cameras is described. The method is analogous to the time-correlated single-photon-counting technique, which is commonly used in atomic physics. By use of short-pulse x-ray radiation from a laser-produced plasma, generated by an ultrafast laser, it is shown that a standard x-ray streak camera with a nominal temporal resol

The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

Popular Abstract in Swedish I gröna växters kloroplaster finns ett s.k. sHsp-protein (small Heat shock protein) som betecknas Hsp21. Det tillhör en grupp av hjälpar-protein som kallas molekylära chaperoner. Chaperoner hjälper andra proteiner så att de inte klibbar ihop, aggregerar och blir inaktiva. Två vattenskyende ytor som sammanförs aggregerar. Genom att särskilt aggregerings-benägna (vattenskThe chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. These methionine residues are situated on one side of an amphipathic alpha-helix.

Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction

Popular Abstract in Swedish Metoder utvecklade inom den statistiska fysiken har visat sig vara användbara även i andra forskningfält såsom datalogi, statistik, ekonomi och molekylärbiologi. I den här avhandlingen undersöks hur en variationell metod, utvecklad för statistisk fysik, kan användas när man löser kombinatoriska optimeringsproblem och när man försöker rekonstruera evolutionsträd. I den Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed. It outperforms the conventional mean-field algorithm, and its performance is comparable to good problem-dedicated

Grundämnessammansättning i olika partikelstorleksfraktioner av den atmosfäriska aerosolen

Beskrivning ges av analysteknik (protoninducerad röntgenstrålning), provtagningsteknik (kaskadimpaktor av Battelle-typ) och provberedningsteknik. Utfört arbete i form av provbehandlingsförbättringar, konstruktion och förbättring av provtagare, bestämning av lämpliga analysparametrar samt uppbyggnad av ett dataprogramsystem presenteras. Sammanställning av resultat i form av beräknade medelvärden i

ARTISTS - huvudgator för alla : Vägledning för planerare och beslutsfattare vid utformning och ombyggnad av huvudgator

Konventionella guider för utformning och förvaltning av trafikleder och stadsgator har vanligtvis inriktats antingen mot huvudtrafikleder eller mot lokala stadsgator. Det är för närvarande brist på ett tydligt och konsekvent angreppssätt för arbetet med utformning av huvudgator där signifikant genomfartstrafik och lokala funktioner kombineras. Målet är att denna rapport ska avhjälpa den bristen ge

Managing overflow in affluent societies

Abstract in Undetermined“It is simply too much” is a common complaint of the modern age. This book looks at how people and institutions deal with overflow - of information, consumption or choices. The essays explore the ways in which notions of overflow – framed in terms of excess and abundance or their implicit opposites, scarcity and dearth – crop up in a number of contexts such as sociological

Event-Based Response Time Estimation

Response time is a measure of quality of service in com- puter systems. Estimation techniques, suitable for support systems for mobile phone systems, are explored. These sys- tems are complex queueing systems with large databases. The trac generated by users and system adminstrators changes rapidly, some loads can be measured other cannot. Attempts to capture all details give models that are not s

Borgar i Skåne

In Skåne there are 167 casles and castle sites. 40 of these sites are described in the book. The intoduction charpter gives a broad view of the danish castle developement from Viking age to renaissance.

Iterative Optimal Control of Liquid Slosh in an Industrial Packaging Machine

Presents an iterative approach to optimal control when modeling errors are present. The problem considered is movement of open containers containing liquid in an industrial packaging machine. The goal is to move as fast as possible without too much slosh. There is no measurement of the slosh available in the machine, therefore open loop control via the acceleration reference is the only possibilit
