(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Foreword
ANALYSIS OF PARAMETERS AFFECTING THE QUALITY OF A CUTTING MACHINE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The quality of cutting machines is affected by several factors that can be directly or indirectly influenced by manufacturers, technicians and users of machine tools. The most critical qualitative evaluation parameters of ...
DESIGN THEORY FOR THE PRESSING CHAMBER IN THE SOLID BIOFUEL PRODUCTION PROCESS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The quality of a high-grade solid biofuel depends on many factors, which can be divided into three main groups - material, technological and structural. The main focus of this paper is on observing the influence of structural ...
CURRENT WAYS TO HARVEST ENERGY USING A COMPUTER MOUSE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
This paper deals with the idea of an energy harvesting (EH) system that uses the mechanical energy from finger presses on the buttons of a computer mouse by means of a piezomaterial (PVF2). The piezomaterial is placed in ...
CFD SIMULATION OF A STIRRED DISHED BOTTOM VESSEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
This paper deals with simulation of the fluid flow in a stirred curved-bottom vessel equipped with three curved blade impellers. The power number and the impeller flow rate number are dimensionless characteristics of the ...
THE EFFECT OF ADDING HYDROGEN ON THE PERFORMANCE AND THE CYCLIC VARIABILITY OF A SPARK IGNITION ENGINE POWERED BY NATURAL GAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
This paper deals with the influence of blending hydrogen (from 0 to 50% vol.) on the parameters and the cyclic variability of a Lombardini LGW702 combustion engine powered by natural gas. The experimental measurements were ...
HYBRID SHEARWALL SYSTEM — SHEAR STRENGTH AT THE INTERFACE CONNECTION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Based on a series of alternating, displacement-controlled load tests on ten one-third scale models, to study the behaviour of the interface of a hybrid shear wall system, it was proved that the concept of hybrid construction ...
AUTOMATIC BIOMASS BOILER WITH AN EXTERNAL THERMOELECTRIC GENERATOR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
This paper presents the design and test results of an external thermoelectric generator that utilizes the waste heat from a small-scale domestic biomass boiler with nominal rated heat output of 25 kW. The low-temperature ...
STABILIZATION TIME AS AN IMPORTANT PARAMETER AFTER DENSIFICATION OF SOLID BIOFUELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The aim of this paper is to present some preliminary results from experimental research on the densification process of solid high-grade biofuels. The findings presented in this paper contribute to an investigation of the ...
THE OPERATING LOAD OF A DISINTEGRATION MACHINE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The process of disintegration is affected by a large number of operating and design parameters which have not previously been described in detail. This paper discusses the effect of the disintegrative surface area on the ...
