A lifeline for the weakest link? Financial contagion and network design
No full textIn "A Lifeline for the Weakest Link? Financial Contagion and Network Design," Yaron Leitner describes how contagion can occur, explains why the threat of contagion is not necessarily a bad thing, and shows why some firms may choose to bail out other firms that are facing financial problems.Contracts ; Financial crises

PERFORMANCE AND EFFICIENCY PF A HYBRID SELF-PROPELLED CABLE LOGGING CARRIAGE: AN EXPERIMENTAL STUDY
No full textGlobal warming and the dependance on expensive fossil fuels in uncertain times are two main drivers for the development of alternative drivetrains. The alpine logging sector is no exception. Indeed, electrification has demonstrated significant potential for fuel savings in cable logging applications, particularly due to the high capacity for energy recovery in cyclic operations involving variations in potential energy. This work presents results of a study involving several key sub-systems as well as the roundtrip efficiency of a hybrid self-propelled carriage called HULK. In addition to performance and efficiency studies of the engine-generator unit, energy dissipation unit and battery system, its two main drive systems, i.e., the dropline winch and the propulsion module, have been evaluated. The tests enabled the performance mapping of key components, identification of optimal operating points, and confirmation of the substantial energy recovery potential. Furthermore, the results highlight the feasibility of energy-autarkic operation in real-world transport applications
Phase matched second harmonic generation from nanostructured metallic surfaces
No full textPlanar structures containing oriented and ordered metallic nanoparticles with shapes lacking an inversion centre can act as a nonlinear medium for generation of second harmonic optical radiation by a process whose directional features resemble those of phase matched second harmonic generation (SHG) in bulk media. The nonlinearity of the metallic patterns stems from the asymmetric modulation of the local field inside nanoparticle by electron oscillations and is deeply rooted in the nanostructured nature of the system. The SHG efficiency is inversely proportional to the second power of the nanoparticle size
Time resolution of TileCal and searches for heavy metastable particles
No full textTitle: Time resolution of TileCal and searches for heavy metastable parti- cles Author: Martina Pagáčová Department: Institute of Particle and Nuclear Physics Supervisor: Doc. RNDr. Rupert Leitner, DrSc. Supervisor's e-mail address: [email protected] Abstract: In the present work, the timing of the ATLAS TileCal is stud- ied using the single hadron collision data. The time resolution and also the mean time response depend on the energy deposited in a given cell. The results are compared to the previous analysis with jets and muons. Precise time-of-flight measurement using TileCal can be used to identify the heavy long-lived particles predicted by the models of physics beyond the standard model. Their mass can be reconstructed by combining with the momentum measurement in the ATLAS inner detector. Finally, the mass resolution of an exotic particle with mass M = 600 GeV is estimated. Keywords: ATLAS experiment, TileCal, time resolution, stable massive particle
