Algorithms for Solving Darcian Flow in Structured Porous Media
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)This paper presents several algorithms that were implemented in DRUtES [1], a new open source project. DRUtES is a finite element solver for coupled nonlinear parabolic problems, namely the Richards equation with the dual ... -
ANALYSIS OF THE ACCURACY OF FIBRE-OPTIC STRAIN GAUGES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In recent years, the field of structure monitoring has been making increasing use of systems based on fiber-optic technologies. Fiber-optic technology offers many advantages, including higher quality measurements, greater ... -
ANALYSIS OF THE MACRO EXPERIMENT DATA TO COMPARE PARTICLE ARRIVAL TIMES UNDER GRAN SASSO
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The claim of a neutrino velocity different from the speed of the light, made in September 2011 by the Opera experiment, suggested the study of the time delays between TeV underground muons in the Gran Sasso laboratory using ... -
Application of Portable Force Platforms Equipped with a Device for Measuring Position and Orientation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)With the development of modern technology for studying the movements of the human body, a large number of new measurement techniques are being applied. However, a complex and expensive device is not always the best one for ... -
ARGO-YBJ: STATUS AND HIGHLIGHTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The ARGO-YBJ experiment has been gathering data steadily since November 2007 at the YangBaJing Cosmic Ray Laboratory (Tibet, P.R. China, 4300m a.s.l., 606 g/cm2). ARGO-YBJ is confronting various open problems in Cosmic Ray ... -
ASTRONOMICAL PLATE ARCHIVES AND SUPERMASSIVE BLACK HOLE BINARIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The recent extensive digitisation of astronomical photographic plate archives, the development of new dedicated software and the use of powerful computers have for the first time enabled effective data mining in extensive ... -
