Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging [PDF]

IEEE transactions on industrial electronics (1982. Print), 2015
In this paper, we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor ...

The asymptotical analysis of the mathematical model of the fluid flow in the elastic pipe

Lietuvos Matematikos Rinkinys, 2011
In this paper the model of the fluid flow in elastic pipe is studied. This model is described by the system of hyperbolic equations. The asymptotic analysis of these equations allows to investigate the conditions of the interaction of waves in the ...

Implementation of a cryo-electron tomography tilt-scheme optimized for high resolution subtomogram averaging

Journal of Structural Biology, 2017
Cryo-electron tomography (cryoET) allows 3D structural information to be obtained from cells and other biological samples in their close-to-native state. In combination with subtomogram averaging, detailed structures of repeating features can be resolved.

Model Averaging and Its Use in Economics [PDF]

Journal of Economic Literature, 2017
The method of model averaging has become an important tool to deal with model uncertainty, for example in situations where a large amount of different theories exist, as are common in economics.

Asymptotic solution of the mathematical model of nonlinear oscillations of absolutely elastic inextensible weightless string

Nonlinear Analysis, 2010
The mathematical model of nonlinear oscillations of weightless string is analyzed. To find an asymptotic solution of the problem, uniformly valid in a long interval of time, an averaged system of integral differential equations has been constructed.

Equitable transform applied to phenology and temperature in a changing climate: Scaling to maintain individuality

Ecosphere, 2020
We describe an equitable transform that can be used to estimate missing data points, determine systematic patterns in data, observe baseline changes, and detect different amplitudes in replicated sequences.
