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 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 ...
Structure and enhanced antimicrobial activity of mechanically activated nano TiO2
(Wiley, Hoboken, 2019)
Titanium dioxide is a photocatalyst, known not only for its ability to oxidize organic contaminants, but also for its antimicrobial properties. In this article, significant enhancement of the antimicrobial activity of TiO2 ...
Prioritizing Strategic Goals in Higher Education Organizations by Using a SWOT–PROMETHEE/GAIA–GDSS Model
(Springer, 2017)
In this paper a hybrid model of SWOT–PROMETHEE/GAIA–GDSS is defined for the purpose of prioritizing strategic goals of the university and developed for the case of the Technical Faculty in Bor that belongs to the group of ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
