Time synchronized low-voltage measurements for Smart Grids
(Elsevier, 2015-11-26)
This paper deals with possible future development of Smart Grids based on more detailed monitoring of grid. The aim of this work is to propose measurements for low-voltage level of Smart Grids inspired by measurements known ...
Simulation of Achievable Data Rates of Broadband Power Line Communication for Smart Metering
(MDPI, 2019-04-12)
This paper presents results of such a simulation study. It is based on realistic PLC channel model implementation in Network Simulator 3, our modification and extension of this implementation for our use case scenario. It ...
A Novel Unique Parameter for Increasing of Security in GPON Networks
(Croatian Communications and Information Society, 2016-07-01)
Pasivní optické sítě jsou široce používané z důvodu jejich dostatečné šířky pásma a nízké ceny jednotlivých prvků. Evropská komise nařizuje ČR, aby do roku 2020 byli stávající zákazníci připojeni alespoň 30 Mbit/s (do ...
Assessment of rail long-pitch corrugation
(IOP Publishing, 2017-09-20)
The paper focuses on defects of the running surface of the rail, namely the rail corrugation defect and specifically long-pitch corrugation in curves of small radii. These defects cause a shorter life of the rails, greater ...
Water chamber geometry and stabilizer construction effect on water pressure distribution of high pressure descaling nozzles
(EDP Sciences, 2012-04-16)
High pressure descaling nozzles are used mainly for removing oxides from hot steel products. The homogeneity and intensity of water pressure distribution on the oxidised surface are very important characteristics for a ...
Mutual collision of water jets from adjacent high pressure flat jet nozzles on flat surfaces during hydraulic descaling
(Technical faculties of the Josip Juraj Strossmayer University of Osijek, 2016-10-13)
High energetic water jets sprayed from nozzles are used for scale removal. Special nozzles with flat and very narrow jets for high feed pressure are used. This process, called descaling, is used in hot rolling, for example. ...
Measurement of the velocity field behind the automotive vent
(EDP Sciences, 2011-11-22)
Passenger comfort in a personal vehicle cabin strongly depends on the appropriate function of the cabin ventilation system. Great attention is therefore paid to the effective functioning of the automotive vents. Various ...
Prevention of discoloration events in water distribution systems
(Elsevier, 2014-04-01)
Mathematical modeling and simulation techniques represent powerful tools for optimizing the operation of drinking water supply networks. Water quality in the distribution systems is affected by the hydraulic regime in the ...
Truck vibrations caused by rotating shaft deflection
(JVE International, 2017-11-15)
The article deals with the creation of a transient computational model of rotating shaft deflection. This model is used for analysis of vibrations in the truck powertrain with an 8x8 drive. This vehicle is intended for ...
Transmission error analysis for heavy-duty gearbox
(JVE Intenational, 2018-05-22)
This paper deals with an analysis of the transmission error. For this purpose, the measuring loop was assembled from two gear boxes. Subsequently, angles, torque and shaft speed were set or measured. For the evaluation a ...
