A Heat Exchanger with Water Vapor Condensation on the External Surface of a Vertical Pipe
(MDPI, 2022-08-03)The paper is concerned with water vapor condensation on vertical pipes. The vertical position of pipes in a condenser is not discussed very often. Its application has a number of particularities in terms of the numerical ... -
X-ray microtomography imaging of craniofacial hard tissues in selected reptile species with different types of dentition
(Oxford University Press, 2022-03-07)Background Reptiles exhibit a large heterogeneity in teeth morphology. The main variability comprises the different tooth shape, the type of tooth attachment to the underlying bone, or the ability to replace the teeth. ... -
Remarkably stable metal-organic frameworks on an inert substrate: M-TCNQ on graphene (M = Ni, Fe, Mn)
(Royal Society of Chemistry, 2022-07-07)Potential applications of 2D metal-organic frameworks (MOF) require the frameworks to be monophase and well-defined at the atomic scale, to be decoupled from the supporting substrate, and to remain stable at the application ... -
Photonic integrated circuits with bound states in the continuum: comment
(Optica Publishing Group, 2022-06-21)We point out that the electro-optic modulation of the bound state in the continuum in a low-index dielectric-loaded slab LiNbO3 waveguide reported by Yu et al., [Optica 6, 1342 (2019)] is treated incorrectly. According to ... -
Centroid based person detection using pixelwise prediction of the position
(ELSEVIER, 2022-07-06)Implementations of person detection in tracking and counting systems tend towards processing of orthogonally captured images on edge computing devices. The ellipse-like shape of heads in orthogonally captured images inspired ... -
Conditions Affecting Wind-Induced PM10 Resuspension as a Persistent Source of Pollution for the Future City Environment
(MDPI, 2022-07-27)Air pollution by particulate matter (PM) in cities is an ongoing problem with increasing severity. The biggest PM contributors are traffic and domestic fire burning. With the shift towards electromobility and the use of ... -
Elastohydrodynamic lubrication of compliant circular contacts near glass-transition temperature
(MDPI, 2022-07-13)Lubrication of polymer materials nowadays represents a subject of interest in many engineering applications, such as bearings or gears, to utilize them in the areas where conventional metal materials have so far dominated. ... -
Twisted Rainbow Light and Nature-Inspired Generation of Vector Vortex Beams
(Wiley-VCH GmbH, 2022-06-06)Twisted vector light beams (optical vortices) arise from a spiral modulation of the geometric (Pancharatnam-Berry) phase converting the light spin to the orbital angular momentum. The preferred geometric-phase elements ... -
Control of Magnetic Manipulator Using Reinforcement Learning Based on Incrementally Adapted Local Linear Models
(WILEY-HINDAWI, 2021-12-20)Reinforcement learning (RL) agents can learn to control a nonlinear system without using a model of the system. However, having a model brings benefits, mainly in terms of a reduced number of unsuccessful trials before ... -
Optimizing GPU performance for cryptocurrency mining using differential evolution
(2015-06-23)Current cryptocurrency market is in its beginnings, develops rapidly and offers many opportunities. The article focuses on a special case where the application of evolutionary optimization leads to a direct and immediate ... -
Optimizing Friction Stir Welding of Dissimilar Grades of Aluminum Alloy Using WASPAS
(MDPI, 2022-02-24)Aluminum is a widely popular material due to its low cost, low weight, good formability and capability to be machined easily. When a non-metal such as ceramic is added to aluminum alloy, it forms a composite. Metal Matrix ... -
Transient response of magnetorheological fluid on rapid change of magnetic field in shear mode
(Springer Nature, 2022-07-09)The transient behaviour of magnetorheological (MR) devices is an important parameter for modern semi-actively controlled suspension systems. A significant part of the MR device response time is the MR fluid response time ... -
The effect of top of rail lubricant composition on adhesion and rheological behaviour
(Elsevier, 2022-01-23)The effect of top of rail lubricant composition on adhesion has been investigated using a laboratory ball-on-disc tribometer. Rheological properties were analysed using viscosimeter and high pressure torsion device. As a ... -
Polymeric hollow fibers: a modular heat exchanger for thermal management systems of battery modules in electric vehicles
(EDP Sciences, 2022-07-11)The liquid-cooling system based on polymeric hollow fibers (1 mm) embedded inside durable polydicyclopentadiene is proposed for thermal management of li-ion cylindrical batteries from their surface. In the present work, a ... -
Cooling of flue gas by cascade of polymeric hollow fiber heat exchangers
(Elsevier, 2022-08-01)Polymeric hollow fibers heat exchangers can be effectively used for flue gas cooling. These heat exchangers are made of hundreds of hollow fibers with an outer diameter of 1.3 mm and a wall thickness of 0.15 mm. Selection ... -
Hight Speed Temperature Measurement
(EDP Sciences, 2022-07-11)In certain applications where temperature changes rapidly, e.g., compressor cylinder or explosion chamber, it is necessary to obtain temperature data with sample rate high enough to register the change, i.e., the temperature ... -
Experimental set up for the investigation of partial phase changes of phase change materials
(EDP Sciences, 2022-07-11)Thermal energy storage with phase change materials (PCMs) has attracted a lot of attention in the last several decades. Most PCMs do not change phase at a constant temperature but rather in a certain temperature range. It ... -
