On construction of the smallest one-sided confidence interval for the difference of two proportions [PDF]

open access: yes, 2010
For any class of one-sided $1-\alpha$ confidence intervals with a certain monotonicity ordering on the random confidence limit, the smallest interval, in the sense of the set inclusion for the difference of two proportions of two independent binomial ...

Design and Application of an Interval Estimator for Nonlinear Discrete-Time SEIR Epidemic Models

open access: yesFractal and Fractional, 2022
This paper designs an interval estimator for a fourth-order nonlinear susceptible-exposed-infected-recovered (SEIR) model with disturbances using noisy counts of susceptible people provided by Public Health Services (PHS).

Analysis of Power-aware Buffering Schemes in Wireless Sensor Networks [PDF]

open access: yes, 2010
We study the power-aware buffering problem in battery-powered sensor networks, focusing on the fixed-size and fixed-interval buffering schemes. The main motivation is to address the yet poorly understood size variation-induced effect on power-aware ...

Moderate and heavy metabolic stress interval training improve arterial stiffness and heart rate dynamics in humans [PDF]

open access: yes, 2012
Traditional continuous aerobic exercise training attenuates age-related increases of arterial stiffness, however, training studies have not determined whether metabolic stress impacts these favourable effects.

Interval State Estimator Design Using the Observability Matrix for Multiple Input Multiple Output Linear Time-Varying Discrete-Time Systems

open access: yesIEEE Access, 2019
In this paper, a novel numerical scheme to set-membership interval state estimator design is proposed for the multiple-input-multiple-output (MIMO) linear time-varying (LTV) discrete-time systems using systems observability matrix and its past input ...

Improved time-interval analysis

open access: yes, 2013
Several extensions of the halflife analysis method recently suggested by Horvat and Hardy are put forward. Goodness-of-fit testing is included, and the method is extended to cases where more information is available for each decay event which allows ...

Generation interval contraction and epidemic data analysis

open access: yes, 2008
The generation interval is the time between the infection time of an infected person and the infection time of his or her infector. Probability density functions for generation intervals have been an important input for epidemic models and epidemic data ...

Finite sampling interval effects in Kramers-Moyal analysis

open access: yes, 2009
Large sampling intervals can affect reconstruction of Kramers-Moyal coefficients from data. A new method, which is direct, non-stochastic and exact up to numerical accuracy, can estimate these finite-time effects.

Multi-level Interval Rolling Warning Method for Distributed Photovoltaic Fluctuation Events

open access: yesZhongguo dianli
Under the influence of large-area extreme weather conditions, the impact of distributed photovoltaic fluctuations on power system balance is significant and may lead to risks such as curtailment of solar power and load shedding.
