Analysis of Implicit Uncertain Systems. Part II: Constant Matrix Problems and Application to Robust H2 Analysis [PDF]

open access: yes, 1994
This paper introduces an implicit framework for the analysis of uncertain systems, of which the general properties were described in Part I. In Part II, the theory is specialized to problems which admit a finite dimensional formulation. A constant matrix

Quantum entanglement and Hawking temperature

open access: yes, 2016
The thermodynamic entropy of an isolated system is given by its von Neumann entropy. Over the last few years, there is an intense activity to understand thermodynamic entropy from the principles of quantum mechanics.

Rationality of admissible affine vertex algebras in the category O

open access: yes, 2014
We study the vertex algebras associated with modular invariant representations of affine Kac-Moody algebras at fractional levels, whose simple highest weight modules are classified by Joseph's characteristic varieties. We show that an irreducible highest

Exponential Stability of Linear Systems with Multiple Time Delays

open access: yesپژوهش‌های ریاضی, 2016
In this paper, a class of linear systems with multiple time delays is studied. The problem of exponential stability of time-delay systems has been investigated by using Lyapunov functional method. We will convert the system of multiple time delays into a

Plane geometry and convexity of polynomial stability regions

open access: yes, 2008
The set of controllers stabilizing a linear system is generally non-convex in the parameter space. In the case of two-parameter controller design (e.g.

Surface water quality in Amazonian Floodplain Lakes, data set of the Lago Grande de Curuai Floodplain Lake, Pará‐Brazil

open access: yesGeoscience Data Journal
Between 2013 and 2017, we carried out nine field missions in the Lago Grande de Curuai floodplain, located in Pará state – North of Brazil – to collect samples for monitoring surface water quality.

Eclipsing Binaries with Possible Light-Time Effect

open access: yes, 2007
The period changes of six eclipsing binaries have been studied with focus on the light-time effect. With the least squares method we also calculated parameters of such an effect and properties of the unresolved body in these systems.

Designing defect-based qubit candidates in wide-gap binary semiconductors for solid-state quantum technologies

open access: yes, 2017
The development of novel quantum bits is key to extend the scope of solid-state quantum information science and technology. Using first-principles calculations, we propose that large metal ion - vacancy complexes are promising qubit candidates in two ...

Increasing Variability in Tropical Cyclone Lifetime Maximum Intensity Over the South China Sea

open access: yesGeophysical Research Letters
Lifetime maximum intensity (LMI) is a key metric for tropical cyclone (TC) intensity, providing insights into TC evolution and impact. However, research on LMI in the South China Sea (SCS) is limited.

Combined Enhanced LMI Charactrization and Parametric Eigenstructure Assignment Using Static Output Feedback [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2012
This paper proposes mixed eigenstructure assignment with H∞ constraint when the states are not measurable. In this case, full state feedback is not permissible. So eigenstructure assignment by output feedback is considered.
