EFFECTS ON THE FINAL INTENSITY OF INPUT FORCES IN LONGBOLTS INSTALLED AT THE MINING OPERATION 2 AREA, OKD, INC.
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
In the deep coal mines of OKD, Inc., both bolts and long bolts of different designs are used for the rock massif and steel arch support reinforcement. Continuous measurement of forces in 6 strand bolts and 1 cable bolt ...
MINIMAL NON-INTEGER ALPHABETS ALLOWING PARALLEL ADDITION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Parallel addition, i.e., addition with limited carry propagation has been so far studied for complex bases and integer alphabets. We focus on alphabets consisting of integer combinations of powers of the base. We give ...
NON-DESTRUCTIVE INSPECTION BY INFRARED THERMOGRAPHY OF RESISTANCE SPOT WELDS USED IN AUTOMOTIVE INDUSTRY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Resistance spot welding (RSW) is one of the main joining technologies of thin sheets in the automotive industry. Key factors affecting the strength of the RSW joint are the nugget diameter, asymmetry, expulsions, intended ...
SIMULATION OF LOW-GRADE COAL COMBUSTION IN REAL CHAMBERS OF ENERGY OBJECTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The aim of the work is to create new computer technologies for 3D modelling of heat and mass transfer processes in high-temperature physicochemically reacting environments that will allow to determine the aerodynamics of ...
TECHNOLOGY OF PRODUCING REINFORCED CONCRETE COLUMNS OF CIRCULAR CROSS-SECTIONAL AND INVESTIGATION OF THEIR STRAIN-STRESS STATE AT TRANSVERSE-LONGITUDINAL BENDING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The paper presents a method of producing Circular Cross-Section Columns (CCSC), which can provide sufficiently precise dimensions, with longitudinal reinforcement securely fixed in special plugs. An investigation procedure ...
INDICATORS FOR COMMON CROSSING STRUCTURAL HEALTH MONITORING WITH TRACK-SIDE INERTIAL MEASUREMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
This paper focuses on the experimental study of an alteration in the railway crossing dynamic response due to the rolling surface degradation during a crossing’s lifecycle. The maximal acceleration measured with the ...
ADSORPTION OF CATIONIC DYE FROM AQUEOUS SOLUTION USING COMPOSITE CHICKEN EGGSHELL - ANTHILL CLAY: OPTIMIZATION OF ADSORBENT PREPARATION CONDITIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
A composite adsorbent was prepared from anthill and eggshell mixture, using an incipient wetness impregnation method and it was used for an adsorption of cationic dye (methylene blue, MB) from an aqueous solution. The ...
GENERAL CALCULATION OF WINDING FACTOR FOR MULTI-PHASE/-LAYER ELECTRICAL MACHINES IRRESPECTIVE OF POLES NUMBER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
In this paper, a method to calculate the winding factor by only considering stator parameters without the rotor ones is developed. This is interesting because it allows the separation of the stator and rotor design, unlike ...
STUDY OF SYNTHETIC DYE REMOVAL USING FENTON/TiO2, FENTON/UV, AND FENTON/TiO2/UV METHODS AND THE APPLICATION TO JUMPUTAN FABRIC WASTEWATER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Synthetic dyes were commonly used in textile industries such as Jumputan fabric industries in South Sumatera. Most of these industries were categorized as a home industry without a wastewater treatment plant, so the ...
ANALYSIS OF THE PROPERTIES OF AW2099 ALUMINIUM-LITHIUM ALLOY WELDED BY LASER BEAM WITH AW5087 ALUMINIUM-MAGNESIUM FILLER MATERIAL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
EN AW2099 aluminium lithium alloy, 2.0mm in thickness, was used as an experimental material. EN AW2099 belongs to the 3rd generation of aluminium lithium alloys. The third generation was developed to improve the disadvantages ...
