LABORATORY TESTING OF THE LEICA AT401 LASER TRACKER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)This paper describes laboratory tests on a Leica AT401laser tracker. As the newer Leica AT402 model also uses the same firmware package, most of the results should also be valid for this device. First, we present the ... -
AD HOC TEAMWORK BEHAVIORS FOR INFLUENCING A FLOCK
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Ad hoc teamwork refers to the challenge of designing agents that can influence the behavior of a team, without prior coordination with its teammates. This paper considers influencing a flock of simple robotic agents to ... -
A MATHEMATICAL MODEL OF GALVANIC CORROSION UNDER THE CONDITIONS OF A THIN ELECTROLYTE FILM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)A mathematical model of galvanic corrosion under the conditions of a thin electrolyte film was used to evaluate atmospheric corrosion. Experimentally determined weight loss values were used to validate the modelled results. ... -

INTEGRAL METHODS FOR DESCRIBING PULSATILE FLOW
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)This paper presents an approximate solution of the pulsatile flow of a Newtonian fluid in the laminar flow regime in a rigid tube of constant diameter. The model is represented by two ordinary differential equations. The ... -
EXPERIMENTAL LEVELLING AT THE INTERFACE OF OPTICAL ENVIRONMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)The article discusses the problems of refraction and its impact on levelling at the interface of optical environments. It describes the influence of a vertical refraction and shows the results of investigating the effect ... -
A QUANTITATIVE EVALUATION OF THE WATER DISTRIBUTION IN A SOIL SAMPLE USING NEUTRON IMAGING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)This paper presents an empirical method by Kang et al. recently proposed for correcting two-dimensional neutron radiography for water quantification in soil. The method was tested on data from neutron imaging of the water ... -
BACK TO BASICS: TOWARDS NOVEL COMPUTATION AND ARRANGEMENT OF SPATIAL SENSORY IN IMAGES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)The current camera has made a huge progress in the sensor resolution and the lowluminance performance. However, we are still far from having an optimal camera as powerful as our eye is. The study of the evolution process ... -
IMPACT OF PLASTIC DEFORMATION ON THE PROPERTIES OF A SELECTED ALUMINIUM ALLOY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)This paper reports on an experiment to assess the influence of plastic deformation on the microstructure and properties of EN AW 6012 (AlMgSiPb) aluminium alloy in two states. The first was the initial state with heat ... -
EXPERIMENTAL EVALUATION OF WEDM MACHINED SURFACE WAVINESS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Wire Electrical Discharge Machining (WEDM) an unconventional machining technology which has become indispensable in many industries. The typical morphology of a surface machined using the electrical discharge technology ... -
ANALYSIS OF INTENSIVELY BLASTED ELECTRIC ARC BURNING IN THE ARC HEATER'S ANODE CHANNEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)The paper deals with the description of the intensively blasted electric arc burning in Ar in the anode channel of the arc heater operated under various conditions. Directly measured experimental data (current, voltage, ... -
COVARIANT INTEGRAL QUANTIZATIONS AND THEIR APPLICATIONS TO QUANTUM COSMOLOGY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)We present a general formalism for giving a measure space paired with a separable Hilbert space a quantum version based on a normalized positive operator-valued measure. The latter are built from families of density operators ... -
ON THE CONSTRUCTION OF PARTIAL DIFFERENCE SCHEMES II: DISCRETE VARIABLES AND SCHWARZIAN LATTICES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)In the process of constructing invariant difference schemes which approximate partial differential equations we write down a procedure for discretizing a partial differential equation on an arbitrary lattice. An open problem ... -
ON PARTIAL DIFFERENTIAL AND DIFFERENCE EQUATIONS WITH SYMMETRIES DEPENDING ON ARBITRARY FUNCTIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)In this note we present some ideas on when Lie symmetries, both point and generalized, can depend on arbitrary functions. We show a few examples, both in partial differential and partial difference equations where this ... -
APPLICATION OF DIMENSIONAL ANALYSIS IN HEAT LOSS DETERMINING IN DISTRICT HEATING SYSTEMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Existing procedures for determining the heat loss in heat distribution use balance relations, or rather they are based on the theory of heat and mass transfer. Dimensional analysis enables a new point of view that demonstrated ... -
