Adaptation of multifractal analysis to segmentation of microcalcifications in digital mammograms
(Elsevier, Amsterdam, 2006)
A method for detecting microcalcifications in digital mammograms is proposed. After recognizing basic features of microcalcifications we introduced several modifications in multifractal analysis, obtaining an efficient ...
A new experimental approach to the calibration of hot-wire probes
(Elsevier Sci Ltd, Oxford, 2009)
Numerous calibration points of the hot-wire probes provide better measurement precision. This is, on the other hand, a time consuming process. Calibration and measurement time is limited by the hot-wire probe sensors ...
Number of trays in gas-liquid columns in case of intensive entrainment: Broadening of the Kremser equation
(Elsevier, Amsterdam, 2007)
The paper deals with the tray efficiency estimation in the presence of entrainment, using one-parametric diffusion model for the column as a whole. The case of mass transfer in the trayed column accompanied by intensive ...
Comments on "Modeling of system dynamics of a slewing flexible beam with moving payload pendulum"
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
This paper comments on the recently published work dealing with the problem of modeling system dynamics of a stewing flexible beam with moving payload. it also includes remarks on the inadequacy in system modeling and ...
Tray-to-tray method for estimation of the number of trays in gas-liquid columns in case of intensive entrainment
(Inst Chemical Engineers, Rugby, 2008)
The paper deals with the tray-to-tray method for determining the required number of trays in gas-liquid columns in case of intensive entrainment. The equations for estimation of the tray efficiency are derived for top, ...
Microwave sintering improves the mechanical properties of biphasic calcium phosphates from hydroxyapatite microspheres produced from hydrothermal processing
(Springer, New York, 2010)
Starting from two microspherical agglomerated HAP powders, porous biphasic HAP/TCP bioceramics were obtained by microwave sintering. During the sintering the HAP powders turned into biphasic mixtures, whereby HAP was the ...
Austempering study of unalloyed and alloyed ductile irons
(MANEY PUBLISHING, LEEDS, 2010)
Austempered ductile iron (ADI) proved to be an advanced material as it possesses remarkable combination of high strength, ductility and toughness with good wear resistance and machinability. These properties can be achieved ...
Failure analysis and redesign of the bucket wheel excavator two-wheel bogie
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
This paper discusses the cause of the failure in the vital part of the crawler travel gear of the bucket wheel excavator (BWE) - two-wheel bogie (TWB). The results of the finite element analysis (FEA) point out that the ...
A trigonometric orthogonality with respect to a nonnegative Borel measure
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2012)
In this paper we consider trigonometric polynomials of semi-integer degree orthogonal with respect to a linear functional, defined by a nonnegative Borel measure. By using a suitable vector form we consider the corresponding ...
Computer simulation of gamma irradiation energy deposition in MOSFET dosimeters
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2006)
The application of MOSFETs as detectors or device components in pulse power technique requires an investigation of their characteristics in radiation fields. Computing possibilities of the renowned programs FOTELP and ...
