Remapping and simulation of EFI system for SI engine using piggyback ECU
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
Electronic fuel injection (EFI) is a complex system, many parts are connected together from mechanical parts to electronic parts to control the internal combustion engine. It must ensure many different works and the most ...
Utilising Pareto efficiency and RSM to adjust binder content in clay stabilisation for Yttre Ringvägen, Malmö
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
In this paper, we present a new framework for improving soil strength using an advanced method of engineering statistics. The materials included clay till collected in Yttre Ringvägen, southern Sweden. Binders included ...
Exact solutions for time-dependent complex symmetric potential well
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
Using the pseudo-invariant operator method, we investigate the model of a particle with a time-dependent mass in a complex time-dependent symmetric potential well V (x, t) = if (t) |x|. The problem is exactly solvable and ...
Derivation of entropy production in a fluid flow in a general curvilinear coordinate system
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
The paper deals with the derivation of the entropy production in the fluid flow performed in a general curvilinear coordinate system. The derivation of the entropy production is based on the thermodynamics laws as well as ...
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, ...
Improving the energy efficiency of a tram’s running gear
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
This research analyses the influence of some design features of an undercarriage of a tram on the energy efficiency in terms of mechanical energy losses during its operation. The work includes the comparison of results of ...
The effects of potassium permanganate on the geotechnical properties of soils
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
In Nigeria, potassium permanganate (KMnO4) is used as a chemical oxidant in the removal of hydrocarbons from polluted soils and groundwater, but there is no information on the effects of KMnO4 on the geotechnical properties ...
From positional representation of numbers to positional representation of vectors
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
To represent real m-dimensional vectors, a positional vector system given by a non-singular matrix M ∈ ℤm×m and a digit set Ɗ ⊂ ℤm is used. If m = 1, the system coincides with the well known numeration system used to ...
Qualitative sign stability of linear time invariant descriptor systems
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
This article discusses assessing the instability of a continuous linear homogeneous timeinvariant descriptor system. Some necessary conditions and sufficient conditions are derived to establish the stability of a matrix ...
Fractional multi-loop active disturbance rejection control for a lower knee exoskeleton system
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
Rehabilitation Exoskeleton is becoming more and more important in physiotherapists’ routine work. To improve the treatment performance, such as reducing the recovery period and/or monitoring and reacting to unpredictable ...
