Identification of geomagnetic pulsations in SQUID data for Space Weather research
(IEEE, 2024)The SQUID records small geomagnetic variations such as pulsations, which are short period fluctuations of the geomagnetic field at ULF frequencies. To distinguish pulsations from uncorrelated noise, the SQUID data is ... -
Identifying the lead angle limit to achieve required surface roughness in ball-end milling
(Springer, 2022)When milling generally shaped surfaces with a ball-end milling tool, machined surface roughness and accuracy as well as machining productivity are often monitored. Improving one of these parameters often causes a decrease ... -
Image analysis of particle size: effect of light source type
(EDP Sciences, 2019)Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. The sizes of particles, bubbles or droplets can be determined by the Image Analysis Technique. ... -
Imaging Michelson interferometer for a low-density gas jet characterization
(American Institute of Physics, 2019)A new optical probing method with increased interferometric sensitivity for a low-density gas jet characterization is presented. The proposed technique employs a Michelson interferometer with a self-imaging object arm, ... -
IMMERSIVE TECHNOLOGIES THAT AID ADDITIVE MANUFACTURING PROCESSES IN CBRN DEFENCE INDUSTRY
(Union of Scientists in Bulgaria, 2021)Testing unique devices or their counterparts for CBRN (C-chemical, B-biological, R-radiological, N-nuclear) defence relies on additive manufacturing processes. Immersive technologies aid additive manufacturing. Their use ... -
Impact of Ageing and the Stability of Adhesion Additive on Moisture Susceptibility and Adhesion
(Trans Tech Publications, 2015)Asphalt mix durability is one of the most important aspects if looking on longer lifetime of pavement structures. It is influences by several factors whereas one of the most important is moisture susceptibility and the ... -
Impact of Channel Correlation on Different Performance Metrics of OSSK-Based FSO Systems
(Institute of Electrical and Electronics Engineers, 2020)In this paper, we study the impact of correlation on the bit error rate (BER) and the channel capacity of a free-space optical (FSO) multiple-input-multiple-output (MIMO) system employing optical space shift keying (OSSK) ... -
The impact of communism on the history of computer development in Eastern Europe.
(NAACE, 2019)The article deals with the history of computer technology in Czechoslovakia in the years 1945 - 1989. It is easier to describe not only significant projects but also to capture the problems of computer technology in ... -
Impact of Electron Irradiation on the ON-State Characteristics of a 4H–SiC JBS Diode
(IEEE, 2015)The ON-state characteristics of a 1.7-kV 4H–SiC junction barrier Schottky diode were studied after 4.5-MeV electron irradiation. Irradiation doses were chosen to cause a light, strong, and full doping compensation of an ... -
Impact of High-Frequency Voltage Distortion Emitted by Large Photovoltaic Power Plant on Medium Voltage Cable Systems
(IEEE Power & Energy Society, 2021)Switching processes of voltage source converters can emit significant high-frequency distortions of frequencies between 5 to 20 kHz. Furthermore, the distortions can partly propagate from the place of their origin into a ... -
The Impact of Key Temperature Measuring Points on Thermal Error Compensation Model Transfer Between Milling Centers of the Same Product Line
(MM Science Journal, 2021)Machine tool thermal errors are an important element in machined workpiece inaccuracies. In the past few decades, thermal errors have been successfully reduced by software compensation techniques such as multiple linear ... -
IMPACT OF PELLETING COST ON COMPETITIVENESS OF INTENTIONALLY GROWN BIOMASS FOR LOCAL SPACE HEATING: CASE EXAMPLE OF THE CZECH REPUBLIC
(Instituto Superior de Engenharia do Porto, 2019)Biomass plays a dominant role in the EU RES portfolio, especially in CE countries. Further development of the use of biomass will require its targeted cultivation on agricultural land. Pellets and briquettes from locally ... -
Impact of Pilots' Tiredness on the Outcome of Psychological Testing
(Wydawnictwo Politechniki Śląskiej, 2019)Presented work is primarily oriented on the experimental verification of the influence of fatigue on the psychological condition of the flying personnel, using psychological and performance tests. For the evaluation of a ... -
Impact of the self-healing agent composition on material characteristics of bio-based self-healing concrete
(Elsevier, 2019)This paper investigates the composition of the biological self-healing agent based on its impact on material characteristics of concrete. A direct addition of the agent – a mixture of bacterial spores and nutrients – into ... -
The Impacts of Unbalance on the Start-up Dynamics of Flexibly Mounted Rotors
(ERGO NOMEN, 2015)The paper deals with the impacts of unbalance on the start-up behaviour of flexibly mounted rotors with viscous damping. It provides an overview of the dimensionless parameters describing the system in question as well as ... -
