The Effect of Kinematic Conditions and Synovial Fluid Composition on the Frictional Behaviour of Materials for Artificial Joints
(MDPI, 2018-05-10)The paper introduces an experimental investigation of frictional behaviour of materials used for joint replacements. The measurements were performed using a ball-on-disc tribometer, while four material combinations were ... -
Notes on iterative closest algorithm
(Institute of Mathematics and Physics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, 2018-03-23)Point clouds are commontly used in many areas of technical practice. Nowadays, the common applications are in area of autonomous cars and 3D terrain or object modelling. During the scanning process, the scanning device or ... -
A Proposal for Simultaneous Training of Reading and Writing Skills Based on a Case of Doctoral Engineering Students
(VUTIUM, 2017-11-10)Writing academic papers is an essential skill that all doctoral students must acquire as from the very beginning of their studies they are required to publish the results of their research in English. For the last four ... -
Comprehensive Study Of Unsteady Pressure Pulsations Induced By The Spiral Vortex Structure In A Conical Diffuser
(Faculty of Technologies and Systems, 2015-09-09)The decelerated swirling flow often breaks down into helical structure which is unstable and causes unsteady velocity and pressure fields. The numerical and experimental investigation of this flow pattern is carried out ... -
Energy transformation and flow topology in an elbow draft tube
(University of West Bohemia, 2012-06-01)Paper presents a computational study of energy transformation in two geometrical configurations of Kaplan turbine elbow draft tube. Pressure recovery, hydraulic efficiency and loss coefficient are evaluated for a series ... -
Effect of Ultrasonication Dispersion Technique on Sintering Properties of CNT Reinforced Al-Zn-Mg-Cu Powder
(Polish Academy of Sciences, 2017-01-01)CNT has been researched significantly due to its properties especially mechanical and conductivity properties. Due to strong affinity between particles, dispersion has been remained a problem for its applications. ... -
Elastic moduli and elastic anisotropy of cold sprayed metallic coatings
(Elsevier, 2016-04-15)Resonant ultrasound spectroscopy is applied to analyze the elastic anisotropy of thick copper, aluminum, titanium, and nickel coatings prepared by cold spraying and to determine the respective elastic moduli. The results ... -
Elastic and Plastic Behavior of the QE22 Magnesium Alloy Reinforced with Short Saffil Fibers and SiC Particles
(MDPI AG, 2018-02-15)Magnesium alloy QE22 (nominal composition 2 wt % Ag, 2 wt % mixture of rare earth elements, balance Mg) was reinforced with 5 vol % Saffil fibers and 15 vol % SiC particles. The hybrid composite was prepared via the squeeze ... -
Proper Orthogonal Decomposition of Pressure Fields in a Draft Tube Cone of the Francis (Tokke) Turbine Model
(IOP Publishing, 2015-01-06)The simulations of high head Francis turbine model (Tokke) are performed for three operating conditions - Part Load, Best Efficiency Point (BEP) and Full Load using software Ansys Fluent R15 and alternatively OpenFOAM ... -
Numerical and experimental investigation of swirling flow in a conical diffuser
(EDP Sciences, 2014-11-18)The decelerated swirling flow often breaks down into helical structure which is unstable and causes unsteady velocity and pressure fields. The numerical and experimental investigation of this flow pattern is carried out ... -
Influence of Scanning Strategies on Processing of Aluminum Alloy EN AW 2618 Using Selective Laser Melting
(MDPI, 2018-02-14)This paper deals with various selective laser melting (SLM) processing strategies for aluminum 2618 powder in order to get material densities and properties close to conventionally-produced, high-strength 2618 alloy. To ... -
Frictional response of lubricant in EHL contact under transient bi-directional shear loading
(Serbian Tribology Society, 2017-12-15)Consideration of performance, efficiency and energy consumption is nowadays an inherent part of the design of every modern machine. These factors are mainly determined by mechanisms taking place within the lubricated ... -
The Enhancement of 3D Scans Depth Resolution Obtained by Confocal Scanning of Porous Materials
(De Gruyter Open, 2017-11-24)Scans of porous materials such as concrete ofr cement paste are highly problematic due to its low depth resolution. We propose an averaging method based on the Lindeberg-Levi theorem that improves the final depth resolution. -
Timing Is Important: Unmanned Aircraft vs. Satellite Imagery in Plant Invasion Monitoring
(Frontiers Media SA, 2017-05-31)The rapid spread of invasive plants makes their management increasingly difficult. Remote sensing offers a means of fast and efficient monitoring, but still the optimal methodologies remain to be defined. The seasonal ... -
Aerodynamic Load Of An Aircraft With A Highly Elastic Wing
(Czech Technical University in Prague, 2017-09-05)In this article, a method for calculation of air loads of an aircraft with an elastic wing is presented. The method can predict a redistribution of air loads when the elastic wing deforms. Unlike the traditional Euler or ...
