Convex optimization of output link scheduling and active queue management in QoS constrained packet switches
Algorithm switches generalized geometric programming convex optimization
2015/8/11
We present two novel algorithms at the ingress and egress of packet switches with QoS provisioning and fairness constraints. We first provide a suite of generalized weighted fair queuing formulations ...
A method for screening active effects in supersaturated designs

A method for screening active effects in supersaturated designs.
A RATIO TEST IN ACTIVE CONTROL NON-INFERIORITY TRIALS WITH A TIME-TO-EVENT ENDPOINT
Active control Fixed margin Fraction retention
2015/3/18
There are essentially two kinds of non-inferiority hypotheses in an active control trial:
fixed margin and ratio hypotheses. In a fixed margin hypothesis, the margin is a
prespecified constant and t...
Step-up Simultaneous Tests for Identifying Active Effects in Orthogonal Saturated Designs
Identifying Active Effects Orthogonal Saturated Designs
2015/3/18
A sequence of null hypotheses regarding the number of negligible
effects (zero effects) in orthogonal saturated designs is formulated. Two
step-up simultaneous testing procedures are proposed to ide...
A method for screening active effects in supersaturated designs
Mixed-level Partial least-squares Supersaturated design
2015/3/18
A sup ersaturated design (SSD) is a design whose run size is not enough for estimating all the main effects. The goal in conducting such a design is to identify,
presumably only a few, relatively dom...
A Closed-Loop Model of the Respiratory System: Focus on Hypercapnia and Active Expiration
Respiratory System Focus on Hypercapnia
2014/12/12
Breathing is a vital process providing the exchange of gases between the lungs and atmosphere. During quiet breathing, pumping air from the lungs is mostly performed by contraction of the diaphragm du...
People born in the Middle East but residing in the Netherlands: Invariant population size estimates and the role of active and passive covariates
Population size estimation capture-Crecapture collapsbility multiple record-systems estimation missing data structural zeros
2012/11/23
Including covariates in loglinear models of population registers improves population size estimates for two reasons. First, it is possible to take heterogeneity of inclusion probabilities over the lev...
Bayesian experimental design for the active nitridation of graphite by atomic nitrogen
Optimal experimental design Uncertainty quantification Bayesian analysis Information gain Mutual information
2011/9/29
Abstract: The problem of optimal data collection to efficiently learn the model parameters of a graphite nitridation experiment is studied in the context of Bayesian analysis using both synthetic and ...
Transitions in active rotator systems: invariant hyperbolic manifold approach
Active rotator model Coupled excitable systems Interacting diffusions FokkerPlanck PDE Normally hyperbolic manifolds Pulsating waves
2011/7/7
Our main focus is on a general class of active rotators with mean field interactions, that is globally coupled large families of dynamical systems on the unit circle with non-trivial stochastic dynami...
Compression-induced failure of electro-active polymeric thin films
actuators electroactive polymers (EAP) compression
2011/1/19
The insurgence of compression induces wrinkling in actuation devices based on EAPs thin films leading to a sudden decrease of performances up to fail-ure.
We review some recent results for a class of fluid mechanics equations called active scalars, with fractional dissipation. Our main examples are the surface quasi-geostrophic equation, the Burgers equ...
Nonlocal maximum principles for active scalars
Nonlocal maximum principles active scalars
2010/11/29
Active scalars appear in many problems of fluid dynamics. The most common examples of active scalar equations are 2D Euler, Burgers, and 2D surface quasi-geostrophic equations. Many questions about re...
Exterior cloaking with active sources in two dimensional acoustics
Active cloaking Acoustic waves Helmholtz equation Green’s formula
2010/12/3
We cloak a region from a known incident wave by surrounding the region with three or more devices that cancel out the field in the cloaked region without significantly radiating waves. Since very litt...
A stability study of the active disturbance rejection control problem by a singular perturbation approach
active disturbance rejection control singular perturbation
2010/9/10
We study the stability characteristic of the active disturbance rejection control for a nonlinear, time-varying plant. To this end, the closed-loop system is reformulated in a form that allows the sin...
