SIMULATION OF A MANEUVERING AIRCRAFT USING A PANEL METHOD
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
We present a method for numerical simulations of a maneuvering aircraft, which uses a first-order unsteady panel method as the only source of aerodynamic forces and moments. By using the proposed method, it is possible to ...
APPLICATION OF GLOBAL OPTIMIZATION TO PREDICT STRAINS IN RC COMPRESSED COLUMNS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
In this paper, the results of an application of global and local optimization methods to solve a problem of determination of strains in RC compressed structure members are presented. Solutions of appropriate sets of nonlinear ...
DAMA RESULTS: DARK MATTER IN THE GALACTIC HALO
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Experimental efforts and theoretical developmens support that most of the Universe is Dark and a large fraction of it should be made of relic particles; many possibilities are open on their nature and interaction types. ...
NON-THERMAL EMISSION FROM CATACLYSMIC VARIABLES: IMPLICATIONS ON ASTROPARTICLE PHYSICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We review the lines of evidence that some cataclysmic variables (CVs) are the sources of non-thermal radiation. It was really observed in some dwarf novae in outburst, a novalike CV in the high state, an intermediate polar, ...
THERMAL AND CHEMICAL EVOLUTIONS OF GALAXY CLUSTERS OBSERVED WITH SUZAKU
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We studied the properties of the intracluster medium (ICM) of galaxy clusters to outer regions observed with Suzaku. The observed temperature dropped by about ~30% from the central region to the virial radius of the clusters. ...
THE IMPACT OF SUZAKU MEASUREMENTS ON ASTROPARTICLE PHYSICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Results from the Suzaku X-ray broad-band observations of clusters of galaxies are summarized. Aiming at understanding the physics of gas heating/particle acceleration and the cluster dynamical evolution, we search for ...
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 ...
RX-J0852−4622: THE NEAREST HISTORICAL SUPERNOVA REMNANT – AGAIN
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
RX-J0852−4622, a supernova remnant, is demonstrated to be closer than 500 pc, based on the measurements of the angular radius, the angular expansion rate and the TeV g-ray flux. This is a new method of limiting the distance ...
SUPERNOVA 1987A: CELEBRATING A SILVER JUBILEE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The story of the SN 1987A explosion is briefly reviewed. Although this supernova was somewhat peculiar, the study of SN 1987A has clarified quite a number of important aspects of the nature and the properties of supernovae, ...
XMM-NEWTON SCIENTIFIC HIGHLIGHTS: X-RAY SPECTROSCOPIC POPULATION STUDIES OF AGN
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
In this paper I review the contribution that the XMM-Newton ESA X-ray mission has given to our understanding of Active Galactic Nuclei, together with other operational, and complementary, X-ray facilities. I will focus on ...
