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 ...
Comparison of methodologies for identification of process parameters affecting geometric deviations in plastic injection molding of housing using Taguchi method
(Kaunas Univ Technol, Kaunas, 2012)
This paper examines parameters that could influence geometric part deviation (shrinkage and warpage) of the Housing (Cycoloy, PC/ABS, Grade C2800) produced by plastic injection molding. Five parameters (temperature of ...
APPLICATION OF NEW CLASSICAL PROBES IN SWIRL FLUID FLOW MEASUREMENTS
(Wiley-Blackwell, Malden, 2010)
Desktop 3-axis parallel kinematic milling machine
(Springer London Ltd, Artington, 2010)
Parallel kinematic machines (PKM) are still a research-and-development topic in many laboratories although many of them, unfortunately, have no PKM at all. Therefore, the use of a desktop educational 3-axis parallel kinematic ...
Experimental and Simulation Testing of Flight Spin Stability for Small Caliber Cannon Projectile
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
The basic aim of this paper is to consider correlations of stability flight criteria, derived as the relations of aerodynamic coefficients and derivatives, on the model of a small caliber cannon spin stabilized projectile. ...
Development and validation of a new universal through flow method for axial compressors
(Sage Publications Ltd, London, 2010)
This article describes the development of a new through flow method for the analysis of axial multi-stage compressors. The method is based on a stream function approach and a finite-element solution procedure. It includes ...
A Model for Shaped Charge Warhead Design
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
A model for shaped charge warhead design was developed. The model is incorporated in the computer code - CUMUL. The code includes detonation wave profile estimation, liner collapse, arrival of collapsed liner to the ...
