COMPARISON OF ACTUAL GROUND SETTLEMENTS IN TUNNELLING EXCAVATION TO MODEL PREDICTIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
It has been discovered that the underground structures are vulnerable to seismic phenomena mainly due to permanent ground deformations caused by earthquakes rather than the dynamic seismic movement itself. Several models ...
SURVEY OF SELECTED PROCEDURES FOR THE INDIRECT DETERMINATION OF THE GROUP REFRACTIVE INDEX OF AIR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The main aim of the research was to evaluate numeric procedures of the indirect determination of the group refractive index of air and to choose the suitable ones for requirements of ordinary and high accuracy distance ...
IMPROVEMENT OF MACHINE SAFETY DEVICES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article presents a development of new machine safety devices, which provide protection of operating elements from overload. Theoretical calculations have been made in order to determine the optimum design, kinematic ...
THERMOCHEMICAL CALCULATIONS USING SERVICEORIENTED ARCHITECTURE IN THE WEB SERVICE FORM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The subject of this article is the service-oriented architecture utilization in the design and implementation of a web service that is intended to perform selected thermochemical calculations for chemical reactions. Computing ...
EXPERIMENTAL CHARACTERIZATION OF A MAGNETOHYDRODYNAMIC POWER GENERATOR UNDER DC ARC PLASMA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The generation of electric power through the conventional systems (thermal and hydroelectric) is no longer sufficient to meet the increasing industrial and commercial usage. Therefore, an alternative energy conversion ...
THE INFLUENCE OF CUTTING CONDITIONS ON THE SELECTED PARAMETERS OF THE SURFACE INTEGRITY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article deals with an investigation of residual stress in machined surface under conditions of high-feed milling and determination of the influence of machining conditions on the size and types of stress resulting from ...
THE USE OF DEM SIMULATION FOR CONFIRMING THE PROCESS OF PARTICULATE MATERIAL MIXING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
At the present time in the research of particulate materials, computer methods that work independently with individual particles are coming to the forefront. One such method is the Discrete Element Method – DEM, which is ...
MULTIDIMENSIONAL HYBRID BOUNDARY VALUE PROBLEM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The purpose of this paper is to discuss three types of boundary conditions for few families of special functions orthogonal on the fundamental region. Boundary value problems are considered on a simplex F in the real ...
EFFECT OF IMPERATA CYLINDRICA REINFORCEMENT FORM ON THE TENSILE AND IMPACT PROPERTIES OF ITS COMPOSITES WITH RECYCLED LOW DENSITY POLYETHYLENE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Composites of recycled low-density polyethylene obtained from waste water-sachets and imperata cylindrica were produced with particulate and long-fibre unidirectional mat reinforcements. Comparison was made of the tensile ...
UPDATED VERSION OF THE SIMPLIFIED MODEL OF INTENSIVELY BLASTED ELECTRIC ARC
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article deals with an improvement of a simplified model of intensively blasted electric arc burning in argon in an anode channel of a modular-type arc heater. Gradually gained experience in the application of the model ...
