A Micromechanics-Based Model for Stiffness and Strength Estimation of Cocciopesto Mortars
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
The purpose of this paper is to propose an inexpensive micromechanics-based scheme for stiffness homogenization and strength estimation of mortars containing crushed bricks, known as cocciopesto. The model utilizes the ...
Evaluation of Bioelectrical Impedance Spectroscopy for the Assessment of Extracellular Body Water
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This study evaluates bioelectrical impedance spectroscopy (BIS) measurements to detect body fluid status. The multifrequency impedance measurements were performed in five female pigs. Animals were connected to an extracorporeal ...
Geometrical Modeling of Concrete Microstructure for the Assessment of ITZ Percolation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Percolation is considered to be a critical factor affecting the transport properties of multiphase materials. In the case of concrete, the transport properties are strongly dependent on the interfacial transition zone ...
Physical and Chemical Aspects of the Nucleation of Cement-Based Materials
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
A theoretical model of the nucleation of portlandite is proposed, and the critical size of a portlandite cluster and the energy barrier of nucleation are determined. The steady state nucleation rate and the time lag of the ...
Micromechanical Analysis of Cement Paste with Carbon Nanotubes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Carbon nanotubes (CNT) are an attractive reinforcement material for several composites, due to their inherently high strength and high modulus of elasticity. There are controversial results for cement paste with admixed ...
Flexible Multi-Electrode Array for Medical Applications
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
A flexible multi-electrode array (MEA) with an embedded silicon chip for electrical stimulation of neurons or for recording action potentials has been manufactured and characterized. Possible improvements for medical ...
A Network Simulation Tool for Task Scheduling
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Distributed computing may be looked at from many points of view. Task scheduling is the viewpoint, where a distributed application can be described as a Directed Acyclic Graph and every node of the graph is executed ...
Energetic Approach to Large Strain Gradient Crystal Plasticity
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
We formulate a problem of the evolution of elasto-plastic materials subjected to external loads in the framework of large deformations and multiplicative plasticity. We focus on a spontaneous inhomogenization interpreted ...
Production of Biocellulosic Ethanol from Wheat Straw
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Wheat straw is an abundant lignocellulosic feedstock in many parts of the world, and has been selected for producing ethanol in an economically feasible manner. It contains a mixture of sugars (hexoses and pentoses).Two-stage ...
Measurement of O2 in the Combustion Chamber of Apulverized Coal Boiler
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Operational measurements of the O2 concentration in the combustion chamber of a pulverized coal boiler are not yet common practice. Operators are generally satisfied with measuring the O2 concentration in the second pass ...
