NETGRAPH – AN EFFICIENT TOOL FOR PERIODIC TIMETABLING AND CAPACITY PLANNING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)A netgraph is a graphical representation of a periodic timetable concept for given spatial or modal scope. It adds a third dimension to the network plan – time. Despite no strictly prescribed rules, a common practice ... -
Neural network based patient recovery estimation of a PAM-based rehabilitation robot
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Rehabilitation robots have shown a promise in aiding patient recovery by supporting them in repetitive, systematic training sessions. A critical factor in the success of such training is the patient’s recovery progress, ... -
NEURINGER-ROSEINWEIG MODEL BASED LONGITUDINALLY ROUGH POROUS CIRCULAR STEPPED PLATES IN THE EXISTENCE OF COUPLE STRESS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)This study intents to scrutinize the impact of ferrofluid in the presence of couple stress for longitudinally rough porous circular stepped plates. The influence of longitudinal surface roughness is developed using the ... -
NEUTRINOLESS DOUBLE BETA DECAY: AN EXTREME CHALLENGE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Neutrino-less Double Beta Decay is the only known way to possibly resolve the nature of neutrino mass. The chances to cover the mass region predicted by the inverted hierarchy require a step forward in detector capability. ... -
NEUTRINOS AS COSMIC MESSENGERS IN THE ERA OF ICECUBE, ANTARES AND KM3NET
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Using neutrinos as cosmic messengers for observation of non-thermal processes in the Universe is a highly attractive and promising vision, which has been pursued in various neutrino telescope projects for more than two ... -
NEUTRINOS FROM ICARUS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Liquid Argon Time Projection Chambers are very promising detectors for neutrino and astroparticle physics due to their high granularity, good energy resolution and 3D imaging, allowing for a precise event reconstruction. ... -
Neutronic analysis of a heat-pipe cooled reactor
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Heat-pipe cooled reactors belong to the group of nuclear reactors using heat pipes filled with liquid metals (such as sodium or potassium) to cool the core. Due to the passive heat removal system, there is no need to use ... -
