Automatic control theory applied to normal and cancer cell proliferation kinetics
(Institute of Oncology Sremska Kamenica, 1997)
In this paper a short review of the existing mathematical models of cell proliferation kinetics is given. The multicompartmental model of the healthy and malignant cells with control in state space is given. The optimization ...
Crack significance evaluation with special reference to welded structures
(Plenum Publ Corp, New York, 1996)
Fracture mechanics parameters (stress intensity factor K-I and its critical value K-Ic, crack opening displacement, and the contour J integral) are originally defined for static and quasistatic loading conditions. On the ...
Numerical and experimental investigation of cooling rates in a spherical casting
(FMJ Int Publications Ltd, Redhill, 1994)
Numerical and experimental investigation of cooling rates in spherical casting (rolling balls made of white alloyed iron) was performed. Temperature history was determined by measurement, using thermocouples (Pt-Pt/Rh), ...
Redundancy problem in writing: From human to anthropomorphic robot arm
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 1998)
This paper presents the analysis of motion of a redundant anthropomorphic arm during the writing. The modeling is based on the separation of the prescribed movement into two motions: smooth global, and fast local motion, ...
On spatial distribution of optical emission in radio frequency discharges
(Journal of Physics D: Applied Physics, 1995)
In this paper we present calculations of the spatial distributions of emission in model argon discharges which correspond to the conditions of argon discharges in the GEC rf reference cell but are relevant for other similar ...
Critical crack assessment procedure for high pressure steam turbine rotors
(Fatigue & Fracture of Engineering Materials & Structures, 1995)
Abstract A critical crack assessment procedure for high pressure steam turbine rotors is introduce and applied. The processes relating to low‐cycle thermal fatigue (LCTF), high‐cycle fatigue (HCF) and creep are considered ...
The influence of excited states on the kinetics of excitation and dissociation in gas mixtures containing methane
(Diamond and Related Materials, 1995)
In this paper, we extend the calculations for rare gas discharges, which aim to establish the influence of excited states on the kinetics of electron-induced excitation, to rare gas-methane mixtures and pure methane which ...
Adaptive fuzzy control of mechanical behavior for a two degree of freedom robotic manipulator
(Kluwer Academic Publ, Dordrecht, 1998)
Active compliance control of robotic manipulators is useful in making robots perform precision assembly operations. The essential requirement here is mechanical isotropy of the robot end-point. In this paper the problem ...
Laser beam effects on Cu and Ti in vacuum and in the air
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Ti and Cu samples were exposed in ambient atmosphere and vacuum (0.66 mPa) to single pulse (0.2-2.6 J) ruby laser radiation in the Q-switch (30 ns) and free generation regimes (150 mu s). Acoustic recordings during irradiation ...
An analytical model for gas absorption in open-channel flow
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
An analytical model is developed for gas absorption in open-channel flow. It is solved in closed-form by the integration of the boundary layer diffusion equation for prescribed four liquid film layers and assumed universal ...
