Linear controller design: Limits of performance via convex optimization
Linear controller design convex optimization linear control system the convex optimization algorithm the controller the transfer matrix
2015/8/12
In this tutorial, an approach to the analysis and design of linear control systems based on numerical convex optimization over closed-loop maps is presented. Convexity makes numerical solution effecti...
Closed-loop convex analysis of performance limits for linear control systems
Linear control system computer aided control system and design a linear controller convex optimization digital signal processor
2015/8/12
In closed-loop convex analysis and design, the linear controller design problem is reformulated as a convex optimization problem, which may be more easily solved than the problems resulting from conve...
Wharton is a zoologist who began his career with studies of parasitic nematodes. The free-living stages of parasitic nematodes possess "extraordinary abilities" (p. ix) to tolerate freezing, desiccati...
This paper reviews several mathematical techniques that have been developed to analyze the asymptotic behavior of waves and particles propagating in a heterogeneous medium. The heterogeneous medium is...

THRESHOLD GRAPH LIMITS AND RANDOM THRESHOLD GRAPHS
Limit theory the threshold figure model random threshold figure
2015/7/8
We study the limit theory of large threshold graphs and apply this to a variety of models for random threshold graphs. The results give a nice set of examples for the emerging theory of graph limits.
INTERVAL GRAPH LIMITS

2015/7/7
We work out the graph limit theory for dense interval graphs. The theory developed departs from the usual description of a graph limit as a symmetric function W(x; y) on the unit square, with x and y ...
In 2012, six Italian seismologists were sent to prison because they failed to predict the 2009 L'Aquila 6.3 magnitude earthquake.To some that may seem absurd but it points to the faith so many have co...
Sensitive limits on the water abundance in cold low-mass molecular cores

2014/12/26
We present Submillimeter Wave Astronomy Satellite observations of water vapor in two cold starless clouds, B68 and core D in ρ Ophiuchi. Sensitive nondetections of the 110-101 transition of o-H2O are ...
Although the existence of large-scale hot gaseous halos around massive disk galaxies has been theorized for a long time, there is yet very little observational evidence. We report the Chandra and XMM-...
Asymptotic limits and the structure of the pion form factor
Dispersion technology solve meson chiral perturbation theory high energy low energy limit
2014/12/22
We use dispersive techniques to address the behavior of the pion form factor as Q2 → ∞ and Q2 → 0. We perform the matching with the constraints of perturbative QCD and chiral perturbation theory in th...
Competition for ecological niches limits the formation of new species
Competition ecological niches limits formation of new species
2014/5/13
The rate at which new species evolve is limited by competition for ecological niches, report scientists from the University of Chicago in Nature on April 30. The study, which analyzes the evolutionary...

2014/7/9
A team of physicists is challenging the very limits of Heisenberg’s famous uncertainty principle by measuring quantum particles with unprecedented accuracy.
The limits of predictability of volcanic eruptions from accelerating rates of earthquakes
Time-series analysis Volcano seismology Statistical seismology
2014/5/19
Volcanic eruptions are commonly preceded by increased rates of earthquakes. Previous studies argue that in some instances these sequences follow the inverse Omori law (IOL) and that this model could b...
Presence of Transcription Factor OCT4 Limits Interferon-tau Expression during the Pre-attachment Period in Sheep
Interferon-tau Transcription Gene regulation Implantation Sheep
2016/5/11
Interferon-tau (IFNT) is thought to be the conceptus protein that signals maternal recognition of pregnancy in ruminants. We and others have observed that OCT4 expression persists in the trophectoderm...
