Virtual oscillator with delayed feedback for transient mitigation in inverter-based islanded microgrids

open access: yesInternational Journal of Renewable Energy Development
In recent years, the conventional control schemes for renewable energy-based inverter-dominated microgrids have been expeditiously replaced by Virtual Oscillator-based Control (VOC).

How can we augment the few that remain? Using stable population dynamics to aid reintroduction planning of an iteroparous species [PDF]

open access: yesPeerJ, 2019
Restoration of depleted populations is an important method in biological conservation. Reintroduction strategies frequently aim to restore stable, increasing, self-sustaining populations.

Transient Population Dynamics [PDF]

open access: yes, 2019
Short-term, transient population dynamics can differ in important ways from long-term asymptotic dynamics. Just as perturbation analysis (sensitivity and elasticity) of the asymptotic growth rate reveals the effects of the vital rates on long-term growth (Chap.

Dynamic Error of Heat Measurement in Transient [PDF]

open access: yes, 2007
According to EN1434 (European Standard) and OIML R-75(International Organization of Legal Metrology), there are two methods in heat measurement, and they are all steady-state methods of test, using them in transient, obvious error will be produced, so some accurately measuring functions should be seeking.

State space analysis of diphtheria pathogenesis using semi-tensor products and permutation methods [PDF]

open access: yesNetwork Biology
In this study, we analyze the state space of a Boolean network modeling diphtheria pathogenesis, focusing on key genes such as Tox, Rep, INF1/INF2, TLR, AP1, IL6, and TNF.

Transient Dynamics of Pinning

open access: yes, 2000
We study the evolution of an elastic string into the pinned state at driving forces slightly below the depinning threshold force $F_c$. We quantify the temporal evolution of the string by an {\it activity function} $A(t)$ representing the fraction of active nodes at time $t$ and find three distinct dynamic regimes.

Prophylaxis of Epidemic Spreading with Transient Dynamics

open access: yesCoRR, 2020
We investigate the containment of epidemic spreading in networks from a normative point of view. We consider a susceptible/infected model in which agents can invest in order to reduce the contagiousness of network links. In this setting, we study the relationships between social efficiency, individual behaviours and network structure. First, we exhibit

Ultrafast transient dynamics in composite multiferroics

open access: yesNew Journal of Physics, 2016
We investigate theoretically the dynamic multiferroic (MF) response of coupled ferroelectric (FE)/ferromagnetic (FM) composites upon excitation by a photo-induced acoustic strain pulse. Two magnetoelectric (ME) mechanisms are considered: interface strain-

Simulation study on impact characteristics of RF microsystem based on bulk silicon MEMS process

open access: yesDianzi Jishu Yingyong
The high overload impact test is costly and time consuming, and the failure detection means are few, so it is difficult to locate the weak points of the structure. In this paper the impact response spectrum and transient dynamics method are used to study
