Improving Affordability and Accessibility for Socially‐Beneficial Services via Government Incentives
Naval Research Logistics (NRL), EarlyView.ABSTRACT Many socially‐beneficial services, like dental care, suffer from a dual challenge: Low affordability for citizens and long waiting times due to insufficient provider capacity. We model a government's problem of designing subsidy policies to address this issue.

On the power of (even a little) resource pooling
Stochastic Systems, 2012 We propose and analyze a multi-server model that captures a performance trade-off between centralized and distributed processing. In our model,a fraction p of an available resource is deployed in a centralized manner (e.g., to serve a most-loaded station)

A fluid queue modulated by a varying Markovian environment
, 2018 We consider an infinite fluid queue modulated by a Markovian environment which varies slowly between two different modes of behaviour. We derive the series expansion of the stationary density of its buffer content as a function of the aggregated ...

Occupation times for the finite buffer fluid queue with phase-type ON-times [PDF]
, 2018 In this short communication we study a fluid queue with a finite buffer. The performance measure we are interested in is the occupation time over a finite time period, i.e., the fraction of time the workload process is below some fixed target level ...

Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire
Networks, EarlyView.ABSTRACT Local councils across the UK are facing sustained financial pressures, and Household Waste Recycling Centres (HWRCs) are being increasingly considered for closure to reduce expenditure. In 2024, Hampshire County Council, which operates the largest HWRC network in the UK, proposed closing either five or twelve existing sites.

Fast Methods for Eikonal Equations: An Experimental Survey
IEEE Access, 2019 Fast methods are very popular algorithms to compute time-of-arrival maps (distance maps measured in time units) solving the Eikonal equation. Since fast marching was proposed in 1995, it has been applied to many different applications, such as robotics ...

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding
People and Nature, EarlyView.Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...

Lévy-driven polling systems and continuous-state branching processes
Stochastic Systems, 2011 In this paper we consider a ring of N ≥ 1 queues served by a single server in a cyclic order. After having served a queue (according to a service discipline that may vary from queue to queue), there is a switch-over period and then the server serves the ...

Path‐Based Deep Reinforcement Learning for On‐Board Routing in Satellite Constellation Networks
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Efficient usage of available network resources is a crucial factor for broadband services in interconnected satellite constellations. To meet required quality of service standards under heavy network loads, it is essential to optimize traffic distribution among the intersatellite links. To address this challenge, we propose an adaptive traffic
