The characterization of the collimated beams of fast neutrons with the clid detection system
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)A new detection device for the measurements of light ions (p, d, t, α) emitted as the products of the nuclear reactions induced by fast neutrons (5-33 MeV) was recently developed at the Nuclear Physics Institute of the ... -
The effect of sampling volume size on the apparent stiffness of jointed rock mass
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Overall mechanical properties of a jointed rock mass are strongly affected by discontinuities – fractures – that naturally occur in rocks. Stochastically-generated discrete fracture network (DFN) modeling, which uses a ... -
THE IMPORTANCE OF A COMBINED 3D MODEL OF GROUND AND GEOTECHNICAL STRUCTURE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The rapid progress of digitalisation in civil engineering is also happening in the branch of geotechnical engineering. BIM is a part of this process. The mutual connection of a 3D model of ground with a 3D model of ... -
The interaction between a driver and intelligent transport systems
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)A road traffic system is a complex system which includes four main parts – human, vehicle, road, and the natural environment. Road safety in Slovakia is based on the strategy of the government, as well as on European ... -
The long-pitch corrugation development in small radii curves
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The paper deals with the phenomenon of long-pitch corrugation in curves of the small radii and also the effects that accelerate or slow down its development. The paper presents data from sections of railway track measured ... -
The New Industrial Revolution: Finding life for the buildings left behind
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)From large generating facilities to modest neighbourhood substations, public power structures are an exercise in dichotomy. Captivating yet mysterious, designed with both powerful function and beauty in mind. Quietly playing ... -
The potential of unused railway areas
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Railway transportation faces many of the issues that are related to standard brownfields - due to changing technologies and industries, more effective systems (of traffic control in this case) and evolving needs many of ... -
The potential use of giant reed from Portugal as a thermal insulation material
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The construction sector plays an important role in climate change. Thus, there is a pressing need to construct buildings that reduce heat losses, use natural and local materials, exploit renewable sources and ensure high ... -
