Optical Hybrid Fiber/Free-Space and 25 GHz Wireless Transmission using LTE M-QAM Signals
(Instituto de Telecomunicaçoes - Lisboa, 2019)
We experimentally demonstrate a seamless hybrid transmission of radio-over-fiber (RoF), radio-over-free-space optics (RoFSO) and millimeter wave wireless link using long-term evolution (LTE) 4/16/64-QAM signals for broadband ...
Infrared Absorption Spectroscopy of Albumin Binding with Amine-Containing Plasma Polymer Coatings on Nanoporous Diamond Surfaces
(American Chemical Society, 2019)
Nanocrystalline diamond (NCD) layers functionalized with amine-containing functional groups have generated considerable interest as biocompatible substrates for attachment of biomolecules and cells with a view to biosensor ...
Visible light communications: multi-band super-Nyquist CAP modulation
(Optical Society of America, 2019)
In this paper, we experimentally demonstrate the performance of a non-orthogonal multi-band super-Nyquist carrier-less amplitude and phase (m-SCAP) modulation for visible light communications (VLC). We break the orthogonality ...
A New Algorithm for Detecting Failure to Clear Mode of Circuit Breakers Using Fundamental Frequency Component of Voltage Signals
(IEEE Power & Energy Society, 2020)
This paper introduces a new algorithm for the early detection of abnormal arcing conditions of circuit breakers (CBs). Any interruption with a higher arcing time compared to maximum permissible arcing time of CB is defined ...
Ultra-wideband mid-infrared supercontinuum generation in liquid-filled circular photonic crystal fiber
(SPIE - International Society for Optical Engineering, 2020)
We numerically demonstrate ultra-wideband mid-infrared supercontinuum (SC) generation in a liquid-filled arsenic–selenide circular photonic crystal fiber (C-PCF). The inner ring air-holes are filled with two different ...
Principles for management of risks of critical infrastructure
(STRIX n.f., Žilina, 2018)
On the basis of present knowledge, the critical infrastructure is a set of physical (technical and material), cyber and organizational subsystems of human system that are necessary for ensuring the protection of: human ...
The efficiency of LED luminaire diffusers
(O.Ö. Energiesparverband, 2019)
The paper describes the influence of diffuser materials used in LED luminaires on properties of light passing through them. It focuses mainly on efficiency and changes in
color properties of light and correlated color ...
Improvement of Voltage Profile and Mitigation of Power Losses in Case of Faults Using DG Units
(Czech Section of the IEEE VUT, 2018)
Distributed generation (DG) units has become an essential part of the smart grid due to increased penetration of renewable energy sources. These units help to improve power quality according to their position and control. ...
Analýza železobetonových konstrukcí po požáru
(Department of Concrete and Masonry Structures, 2018)
Příspěvek se zabývá problematikou železobetonových konstrukcí za, resp. po požáru. Formou rešerše popisuje postup po skončení požáru, ohledání konstrukce a možnosti zkoušek zasažených konstrukcí. Dále je charakterizováno ...
Optimization of Local Cogeneration Stations
(Czech Section of the IEEE VUT, 2018)
This paper presents a mathematical model that is developed to economically optimize a small and a medium-sized local cogeneration system. This model was developed to find the economically optimal configuration of the ...
