Self-organization and control around flocks mills is studied for second-order swarming systems involving self-propulsion potential terms. It shown that through the action of constrained control, it possible to any initial configuration a flock or mill. The proof builds on an appropriate combination several arguments: LaSalle invariance principle Lyapunov-like decreasing functionals, linearizati...

Abstract We consider a second-order elliptic boundary value problem with strongly monotone and Lipschitz-continuous nonlinearity. design study its adaptive numerical approximation interconnecting finite element discretization, the Banach–Picard linearization, contractive linear algebraic solver. In particular, we identify stopping criteria for solver that on one hand do not request an overly ti...

We present a post-distortion linearization technique for semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) photonic sampler. The sampling source is an active mode-locked laser producing 12.6 ps-width pulses with repetition frequency of 10 GHz. mathematical model the presented and then evaluated quasi-static regime, i.e. continuous-wave signals, dynamic sinusoidal signals.

The paper deals with a problem of linearization of multi-output logic functions. Specifically, the case is discussed, when the functions have a large number of variables and cannot be efficiently linearized by using known techniques. For solution of the problem a socalled piecewise linearization is proposed. The piecewise linearization comprises decomposition of an initial multi-output function...

a digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. the system is designed in ka-band for a dvb-s2 satellite link. we use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. the six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. this approa...

Perceptual linearization has been advocated for medical image presentation, both for the faithful reproduction of images, and for standardizing the appearance across different display devices. At this time, few studies have attempted to evaluate the effectiveness of a post-processing perceptual linearization step. We have recently analyzed the methods for computing perceptual linearization rema...

In this paper, a comprehensive numerical study is presented for studying the MHD flow and heat transfer characteristics of non-Newtonian micropolar fluid through a porous medium between two stretchable porous disks. The system of governing equations is converted into coupled nonlinear ordinary ones through a similarity transformation, which is then solved using Quasi-linearization ...
