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 ...
FABRICATION OF Mg-Zn-Al HYDROTALCITE AND ITS APPLICATION FOR Pb<sup>2+</sup> REMOVAL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The fabrication of Mg-Zn-Al Hydrotalcite (HT) was carried out by the co-precipitation method at various molar ratios. The Mg-Zn-Al HT compound at the optimum molar ratio was then calcined to determine the effect of calcination ...
DEFLECTIONS AND FREQUENCY ANALYSIS IN THE MILLING OF THIN-WALLED PARTS WITH VARIABLE LOW STIFFNESS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The disadvantage of the geometry of thin-walled parts, in terms of processing, is the low ability to resist static and dynamic loads. It is caused by the elastic deformation of elements with a low stiffness. Modelling ...
COMPARATIVE STUDY AND EMPIRICAL MODELLING OF PULVERIZED COCONUT SHELL, PERIWINKLE SHELL AND PALM KERNEL SHELL AS A POZZOLANS IN CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Infrastructural development across the world is fast growing due to the rapid growth in population. This has resulted in consequently creating an increase in the demand for construction materials, especially cement. This ...
MODEL-BASED SECURITY ANALYSIS OF FPGA DESIGNS THROUGH REINFORCEMENT LEARNING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Finding potential security weaknesses in any complex IT system is an important and often challenging task best started in the early stages of the development process. We present a method that transforms this task for FPGA ...
3-D MODELING OF HEAT AND MASS TRANSFER PROCESS DURING THE COMBUSTION OF SOLID FUEL IN A SWIRL FURNACE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
In this work, a comprehensive study of thermal processes and aerodynamic and concentration characteristics of the combustion chamber of the boiler BKZ-75 of the Shakhtinskaya thermal power plant (Kazakhstan) are presented. ...
GAS-PUFF TARGET FOR LASER-PRODUCING PLASMA SXR SOURCE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
Mass density spatial distributions of selected gas-puff targets have been determined by radiography, using quasi-monochromatic radiation at a wavelength of 13 nm. Results of spatial distributions of mass densities at various ...
