Comparative approaches for assessing access to alcohol outlets: exploring the utility of a gravity potential approach. [PDF]

open access: yes, 2016
BackgroundA growing body of research recommends controlling alcohol availability to reduce harm. Various common approaches, however, provide dramatically different pictures of the physical availability of alcohol.

Multi‐UAV cooperative trajectory optimisation for a multi‐hop UAV relaying network

open access: yesElectronics Letters, 2021
In this letter, an unmanned aerial vehicle (UAV) assisted data collection scenario is considered in the Internet of Things (IoT), where a multi‐hop UAV relaying network is constructed for real‐time data transmission.

Urban Intersection Signal Control Based on Time-Space Resource Scheduling

open access: yesIEEE Access, 2021
This paper improves the level of urban traffic control by creasing the dimension of control variables. It focuses on roads rather than vehicles. A new space-time resource scheduling model and a bi-level optimization control method for urban intersections

Model identification and parametric adaptive control of hydraulic manipulator with neighborhood field optimization

open access: yesIET Control Theory & Applications, 2021
The model identification and uncertain parameters estimation are common control problems in multi‐DOF manipulator system, since both model parametric uncertainties and unknown external disturbance often degrade the output performance and the close‐loop ...

On a multi-species Cahn-Hilliard-Darcy tumor growth model with singular potentials [PDF]

open access: yes, 2017
We consider a model describing the evolution of a tumor inside a host tissue in terms of the parameters $\varphi_p$, $\varphi_d$ (proliferating and dead cells, respectively), $u$ (cell velocity) and $n$ (nutrient concentration). The variables $\varphi_p$,

Controlling factors for the spatial variability of soil magnetic susceptibility across England and Wales [PDF]

open access: yesEarth-Science Reviews, 2009
Abstract We review the nature and importance of soil factors implicated in the formation of secondary ferrimagnetic minerals in soils and palaeosols worldwide. The findings are examined with respect to temperate regions through a comprehensive analysis of over 5000 samples of surface soil from England and Wales taken from a 5 × 5 km grid.

Fractional order sliding mode control based on single parameter adaptive law for nano‐positioning of piezoelectric actuators

open access: yesIET Control Theory & Applications, 2021
A fractional order sliding mode control (FOSMC) based on single parameter adaptive law for nano‐positioning of Piezoelectric Actuators (PEAs) is proposed.
