  2. 6. A Sequence of Essays on Sequences of Auctions

    Author : Daniel Bougt; Ola Andersson; Per Hjertstrand; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; declining price anomaly; sequential auctions; train-ticket auctions; ambiguity aversion; risk aversion; non-parametric estimation; experiment; Economics; Nationalekonomi;

    Abstract : Essay I (with Gagan Ghosh and Heng Liu). The existence of declining prices in sequential auctions is a well-documented empirical pattern. Three explanations that can explain the puzzle are bidders being risk averse, loss averse, or ambiguity averse. READ MORE

  4. 7. Unmasking fault tolerance : Quantifying deterministic recovery dynamics in probabilistic environments

    Author : Nils Müllner; Germany Carl von Ossietzky Universität Oldenburg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present book focuses on distributed systems operating under probabilistic influences like faults. How well can such systems provide their service under the effects of faults? How well can they recover from faults? Along with a thorough introduction into the area of fault tolerance, this book introduces a measure called limiting window availability to answer such questions. READ MORE

  5. 8. Changing the Rules of the Game : A Market Microstructure Perspective on the Effects of Regulating Financial Markets

    Author : Ester Félez Viñas; Björn Hagströmer; Caihong Xu; Mathijs van Dijk; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Market fragmentation; liquidity; resiliency; short selling ban; commonality in liquidity; financial contagion; call auction; market integrity; auction attractiveness; price efficiency; företagsekonomi; Business Administration;

    Abstract : This dissertation contains four articles that examine the effects brought about by the implementation of new regulations and changes in the trading landscape on different facets of market quality and integrity.Article I studies how the fragmentation of equity markets affects the speed of recovery of the market, both under normal market conditions and in times of stress.

  6. 9. Charged particle distributions and robustness of the neural network pixel clustering in ATLAS

    Author : Edvin Sidebo; Jonas Strandberg; Bengt Lund-Jensen; David Silvermyr; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; p p: scattering; ATLAS; LHC; charged particle: multiplicity; semiconductor detector: pixel; neural network: performance; track data analysis: cluster; charged particle: cluster; splitting; CERN LHC Coll; Fysik; Physics;

    Abstract : This thesis contains a study of the robustness of the artificial neural network used in the ATLAS track reconstruction algorithm as a tool to recover tracks in dense environments. Different variations, motivated by potential discrepancies between data and simulation, are performed to the neural network’s input while monitoring the corresponding change in the output. READ MORE

  7. 10. On the Design and Analysis of Stream Ciphers

    Author : Martin Hell; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; weak feedback polynomials; bit-search generator; self-shrinking generator; Achterbahn; Pomaranch; Grain-128; Grain; stream ciphers; cryptography; cryptanalysis; Informatics; systems theory; Informatik; systemteori;

    Abstract : This thesis presents new cryptanalysis results for several different stream cipher constructions. In addition, it also presents two new stream ciphers, both based on the same design principle. The first attack is a general attack targeting a nonlinear combiner. READ MORE
