Early detection of variants of concern via funnel plots of regional reproduction numbers

Scientific Reports, 2023
Early detection of the emergence of a new variant of concern (VoC) is essential to develop strategies that contain epidemic outbreaks. For example, knowing in which region a VoC starts spreading enables prompt actions to circumscribe the geographical ...

Large-Scale Deployment of Lehmann’s Funnel Entry Traps to Control Malaria Mosquito Populations

Tropical Medicine and Infectious Disease
Effective tools to prevent mosquito bites are essential for malaria control. The Lehmann Funnel Entry Trap (LFET), a window screen proven effective in reducing mosquito density, was tested for its large-scale impact on malaria vector control and ...

Comparison of capture and escape rates between different types of portable cowbird traps

Wildlife Society Bulletin, 2014
Control of brown‐headed cowbirds (Molothrus ater) is often advocated to reduce parasitism and improve nesting success of sensitive populations of passerine birds, but little information is available in the literature concerning the relative effectiveness

Research on Control Strategy of 3-DOF Electro-Hydraulic Servo Manipulator Based on Active Disturbance Rejection Controller

IEEE Access
To address the high-precision control requirements of a three-degree-of-freedom (3-DOF) electro-hydraulic servo robotic arm, this paper innovatively integrates the funnel control (FC) concept into the compensation structure of an active disturbance ...

The impact of disease severity adjustment on hospital standardised mortality ratios: Results from a service-wide analysis of ischaemic stroke admissions using linked pre-hospital, admissions and mortality data.

PLoS ONE, 2019
BACKGROUND:Administrative data are used to examine variation in thirty-day mortality across health services in several jurisdictions. Hospital performance measurement may be error-prone as information about disease severity is not typically available in ...

MU-SYNTHESIS BASED ACTIVE ROBUST VIBRATION CONTROL OF AN MRI INLET

Facta Universitatis. Series: Mechanical Engineering, 2016
In this paper, a robust control technique based on μ-synthesis is employed in order to investigate the vibration control of a funnel-shaped structure that is used as the inlet of a magnetic resonance imaging (MRI) device. MRI devices are widely subjected

Observer-based and funnel-based predefined-time event-triggered adaptive formation tracking control for multiple quadrotors

Results in Engineering
This paper designs a predefined-time event-triggered formation control (PEFC) scheme for multiple quadrotors with unknown external disturbances. In the position system, the designed predefined-time distributed state observer (PTDSO) is utilized to ...
