Optimization of energy consumption in buildings with hydronic heating systems considering thermal comfort by use of computer-based tools
(Elsevier Science Sa, Lausanne, 2007)
The paper deals with an optimization of parameters, which influence the energy and investment cost as well as the thermal comfort. The parameters considered in this study are: the insulation thickness of the building ...
Comparative Studies of the Structural and Physicochemical Properties of the First Fullerene Derivative FD-C60 (Fullerenol) and Second Fullerene Derivate SD-C60 (3HFWC)
(Nanomaterials, 2024)
In order to maximally reduce the toxicity of fullerenol (the first derivative of C60, FD-C60), and increase its biomedical efficiency, the second derivative SD-C60 (3HFWC, Hyper-Harmonized Hydroxylated Fullerene Water ...
Lignin based microspheres for effective dyes removal: Design, synthesis and adsorption mechanism supported with theoretical study
(Elsevier, 2023)
Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological ...
Microstructure and fracture of alloyed austempered ductile iron
(Elsevier Science Inc, New York, 2006)
An investigation has been conducted on two austempered ductile irons alloyed with Cu and Cu+Ni, austenitized at 900 degrees C and austempered at 350 degrees C. The microstructure and fracture mode developed through these ...
Generalized scalar equilibrium problem with applications to best and coupled best approximations
(SPRINGER Basel AG, Basel, 2017)
In this paper, we present a new theorem on the existence of solutions for a three-function scalar equilibrium problem. Compactness is expressed in terms of the existence of feasibility sets of arbitrarily small measures ...
Conditions of regularity in cone metric spaces
(Elsevier Science Inc, New York, 2011)
In this paper we prove some fixed points results on cone metric spaces for maps satisfying general contractive type conditions. Among other things, we extend some results of Nguyen [11] from metric spaces to cone metric ...
Numerical Investigation and Optimization of a Morphing Airfoil Designed for Lower Reynolds Number
(MDPI, 2024)
A novel concept of morphing airfoils, capable of changing camber and thickness, is proposed. A variable airfoil shape, defined by six input parameters, is achieved by allowing the three spinal points (at fixed axial ...
Air side heat transfer coefficient in plate finned tube heat exchangers
(Taylor & Francis Inc, Philadelphia, 2020)
In order to establish a reliable procedure for estimation of heat transfer coefficient, experiments on plate finned tube heat exchangers have been conducted on five exchangers. Using own and previously published experimental ...
Numerical Analysis of NOx Control by Combustion Modifications in Pulverized Coal Utility Boiler
(Amer Chemical Soc, Washington, 2012)
Considerable research efforts focus on modeling NOx formation/destruction and predicting NOx emission so that it can be controlled. A motivation for this numerical study was to examine the efficiency of combustion modifications ...
Bucket wheel excavator Integrity assessment of the bucket wheel boom tie-rod welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The bucket wheel boom tie-rods are vital structural parts of the bucket wheel excavators (BWE) Their failures inevitably cause BWE collapse and are followed among other things by a substantial financial loss (millions of ...
