Context sensitive recognition of abrupt changes in cutting process
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
This paper presents a new generic approach to real-time monitoring of abrupt changes in cutting process. Proposed method is based on hierarchical fuzzy clustering of patterns obtained from discrete wavelet transform (DWT) ...
Measurement and analysis of angular velocity variations of twelve-cylinder diesel engine crankshaft
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
This paper presents the procedures for measuring and analyzing the angular velocity variation of twelve-cylinder diesel engine crankshaft on its free end and on the power-output end. In addition, the paper deals with ...
Effect of Excess Air Ratio and Temperature on NOx Emission from Grate Combustion of Biomass in the Staged Air Combustion Scenario
(Amer Chemical Soc, Washington, 2011)
The combustion of biomass, in this case demolition wood, has been investigated in a grate combustion multifuel reactor. In this work a temperature range of 850-1000 degrees C is applied both for staged air combustion and ...
Asymptotic behavior of orthogonal trigonometric polynomials of semi-integer degree
(Elsevier Science Inc, New York, 2012)
Orthogonal systems of trigonometric polynomials of semi-integer degree with respect to a weight function w(x) on (0, 2 pi) have been considered firstly by Turetzkii [A.H. Turetzkii, On quadrature formulae that are exact ...
The contraction principle for set valued mappings on a metric space with a graph
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Let (X, d) be a metric space and F : X hooked right arrow X be a set valued mapping. We obtain sufficient conditions for the existence of a fixed point of the mapping F in the metric space X endowed with a graph G such ...
Possibility of the abrasive wear resistance determination with scratch tester
(Springer/Plenum Publishers, New York, 2010)
Abrasion wear resistance is very important in many applications and it is not a surprise that there are many laboratory test methods for its determination. In this article, a possibility of the abrasive wear resistance ...
Mock-up testing facilities and qualification strategy for EU ITER TBMs
(Elsevier Science Sa, Lausanne, 2010)
European test blanket modules (TBM) for both European blanket concepts, namely the Helium Cooled Lithium Lead (HCLL) and the Helium Cooled Pebble Bed (HCPB), and their auxiliary systems have been designed in the last years. ...
Failure analysis of the combat jet aircraft rudder shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper analyzes failure causes of the combat jet aircraft rudder shaft (RS) which occurred during the flight mission. A finite element method (FEM), utilized to determine the stress state of the RS subjected to hinge ...
Neural network prediction of brake friction materials wear
(Elsevier Science Sa, Lausanne, 2010)
Wear of brake friction materials depends on many factors such as temperature, applied load, sliding velocity, properties of mating materials, and durability of the transfer layer. Prediction of friction materials wear ...
Abstract metric spaces and Sehgal-Guseman-type theorems
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Recently, Raja and Vaezpour [P. Raja and S.M. Vaezpour, Some extensions of Banach's contraction principle in complete cone metric spaces, Fixed Point Theory Appl. 2008, 11 pages, doi:10.1155/2008/768294. Article ID 768294] ...
