A new form of equations for rigid body rotational dynamics
(Strojarski Facultet, 2014)
In the paper, a new form of differential equations for rigid body attitude dynamics is obtained. Three s-parameters (modified Rodrigues-Hamilton parameters) and three angular velocity parameters are used as unknown variables. ...
Triz method application for improving the special vehicles maintenance
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
TRIZ methodology provides an opportunity for improving the classical engineering approach based on personal knowledge and experience. This paper presents the application of TRIZ methods for improving vehicle maintenance ...
Primena multivarijantne analize i samo-organizujućih mapa za analizu podatka dobijenih na osnovu opto-magnetnih spektara vode / Multivariate analysis and self organizing feature maps applied for data analysis of opto-magnetic spectra of water
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Kako bi se došlo do novih saznanja u vezi strukture vode u tečnom stanju, kao i interakcija između rastvorenih materija i molekula vode korišćena je nova metoda bazirana na upotrebi opto-magnetne imidžing spektroskopije ...
Razvoj inženjerske ontologije za domen koordinatne metrologije / Developing engineering ontology for domain coordinate metrology
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Već razvijene i primenjene inženjerske informacije, često su skladištene i zaboravljene. Trenutni pristupi pretraživanju informacija su nedovoljno efikasni u razumevanju inženjerskih sadržaja, jer oni nisu razvijeni tako ...
A New Loss and Deviation Model for Axial Compressor Inlet Guide Vanes
(ASME, New York, 2014)
This paper describes a new universal algebraic model for the estimation of flow deflection and losses in axial compressor inlet guide vane devices. The model deals with nominal flow and far-off-design operating conditions ...
Techno-economic optimization of plant for raw ethanol production based on experimental data
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper concerns techno-economic optimization of the production process of raw ethanol in a continuous distillation column as a part of the plant for production of rectified alcohol. Optimization was performed in order ...
Optimization of stiffened pannels based on quasi-analytical strength response functions
(National Technical University of Athens, 2014)
Stiffened panels are basic constituents of wide scope of structures, their optimization being the focal point of optimization of any such structure as a whole. The main obstacle in application of sophisticated optimization ...
On the brachistochronic motion of a variable-mass mechanical system in general force fields
(Sage Publications Ltd, London, 2014)
The problem of the brachistochronic motion of a mechanical system composed of rigid bodies and variable-mass particles is solved. The laws of the time-rate of mass variation of the particles as well as relative velocities ...
Fractals model of technology efficiencies probabilities for flexible use in combat units
(Palgrave Macmillan, 2014)
Recent uncertain war challenges and innovative war games are strongly determined with combat and non-combat defense technologies. From the point of view of the missions tasks, these contents are usually composed of a ...
Active boundary layer control in linear cascades using CFD and artificial neural networks
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Flow field in linear cascades under high subsonic/transonic conditions has been investigated numerically. Active boundary layer control was employed in the form of sources (jets) distributed across the upper surface of the ...
