The Gibbs paradox, the Landauer principle and the irreversibility associated with tilted observers
, 2017 It is well known that, in the context of General Relativity, some spacetimes, when described by a congruence of comoving observers, may consist in a distribution of a perfect (non-dissipative) fluid, whereas the same spacetime as seen by a "tilted ...

The Multiple Faces of Reflexive Research Designs [PDF]
Journal of Systemics, Cybernetics and Informatics, 2015 Reflexive research can be grouped into five clusters with circular relations between two elements x ↔ x, namely circular relations between observers, between scientific building blocks like concepts, theories or models, between systemic levels, between ...

Covert channels in stochastic cyber‐physical systems
IET Cyber-Physical Systems, 2021 A covert channel is a communication channel that is not intended to exist, and that can be used to transfer information in a manner that violates the system security policy. Attackers can abuse such channels to exfiltrate sensitive information from cyber‐

Robust Output Feedback Control of the Voltage Source Inverter in an AC Microgrid
Energies, 2022 This paper presents the mathematical model and control of the voltage source inverter (VSI) connected to an alternating current (AC) microgrid. The VSI used in this work was a six-switch three-phase PWM inverter, whose output voltages were controlled in ...

The Post-Quasistatic Approximation as a test bed for Numerical Relativity
, 2009 It is shown that observers in the standard ADM 3+1 treatment of matter are the same as the observers used in the matter treatment of Bondi: they are comoving and local Minkowskian.

International Journal of Applied Mathematics and Computer Science, 2017 The design of an interval observer for estimation of unmeasured state variables with application to drinking water distribution systems is described. In particular, the design process of such an observer is considered for estimation of the water quality ...

Quadratic Performance Analysis of Switched Affine Time–Varying Systems
International Journal of Applied Mathematics and Computer Science, 2018 We analyze quadratic performance for switched systems which are composed of a finite set of affine time-varying subsystems, where both subsystem matrices and affine vectors are switched, and no single subsystem has desired quadratic performance.

Quantized Detector Networks: A review of recent developments
, 2007 QDN (quantized detector networks) is a description of quantum processes in which the principal focus is on observers and their apparatus, rather than on states of SUOs (systems under observation).
