THREE-VARIABLE ALTERNATING TRIGONOMETRIC FUNCTIONS AND CORRESPONDING FOURIER TRANSFORMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
The common trigonometric functions admit generalizations to any higher dimension, the symmetric, antisymmetric and alternating ones. In this paper, we restrict ourselves to three dimensional generalization only, focusing ...
ULTRASONIC SOLDERING OF Cu AND Al2O3 CERAMICS BY USE OF Bi-La AND Bi-Ag-La SOLDERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
This work deals with the effect of solder alloying with a small amount of lanthanum on joint formation with metallic and ceramic substrate. The Bi-Ag – based solder with 2 wt.% lanthanum addition and Bi solder with 2 wt.% ...
HYBRID REASONING FOR MULTI-ROBOT DRILL PLANNING IN OPEN-PIT MINES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
Fleet automation often involves solving several strongly correlated sub-problems, including task allocation, motion planning, and coordination. Solutions need to account for very specific, domaindependent constraints. In ...
TESTING THE ACCURACY OF MEASURED VALUES IN CONTINUOUS LONG-TERM GEODETIC MONITORING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
widespread used method. In this paper, an analysis of the accuracy and its changes over time of the measured values in continuous geodetic monitoring is presented. For the analysis, a set of data measured in the period of ...
TWO-DIMENSIONAL HYBRIDS WITH MIXED BOUNDARY VALUE PROBLEMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
Boundary value problems are considered on a simplex F in the real Euclidean space R2. The recent discovery of new families of special functions, orthogonal on F, makes it possible to consider not only the Dirichlet or ...
IS PT-SYMMETRIC QUANTUM THEORY FALSE AS A FUNDAMENTAL THEORY?
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
Yi-Chan Lee et al. claim (cf. Phys. Rev. Lett. 112, 130404 (2014)) that the “recent extension of quantum theory to non-Hermitian Hamiltonians” (which is widely known under the nickname of “PT-symmetric quantum theory”) is ...
TESTS ON 10.9 BOLTS UNDER COMBINED TENSION AND SHEAR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
Prior investigations of the load-bearing capacity of bolts during fire have shown differing behaviour between bolts that have been loaded by shear or by tensile loads. A combination of the two loads has not yet been examined ...
FORMATION CONTROL OF MULTIPLE UNICYCLE-TYPE ROBOTS USING LIE GROUP
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
In this paper the formation control of a multi-robots system is investigated. The proposed control law, based on Lie group theory, is applied to control the formation of a group of unicycle-type robots. The communication ...
RESIDUAL PROPERTIES OF FIBER-REINFORCED REFRACTORY COMPOSITES WITH A FIRECLAY FILLER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
The aim of our study was to develop a composite material for industrial use that is resistant to the effect of high temperatures. The binder system based on aluminous cement was modified by adding finely-ground ceramic ...
SIMULATION OF SURFACE HEATING FOR ARBITRARY SHAPE’S MOVING BODIES/SOURCES BY USING R-FUNCTIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
The purpose of this article is to propose an efficient algorithm for determining the place of an action of a heat source with a given motion law for a body of an arbitrary shape using methods of analytical geometry. The ...
