The role of drones in disaster response: A literature review of operations research applications
International Transactions in Operational Research, Volume 32, Issue 2, Page 545-589, March 2025.Abstract The increasing use of drones has led to growing interest in their potential applications in disaster response. In this study, we examine the role of drones in disaster management under three categories of operation types, which are information collection, delivery, and communication network recovery.

Dynamics and Control of Sugarcane Smut Using Deterministic and Stochastic Epidemic Models
Natural Resource Modeling, Volume 38, Issue 1, February 2025.ABSTRACT Sugarcane smut disease is a serious issue for farmers as it can greatly reduce sugarcane yield. It is important to manage this disease effectively to prevent economic losses. Farmers can use resistant varieties of sugarcane, remove diseased plants manually, or apply appropriate fungicides to control the spread of the disease; however, the ...

MODELLING A MULTITYPE BRANCHING BROWNIAN MOTION: FILTERING OF A MEASURE-VALUED PROCESS
, 2006 In the framework of marked trees, a multitype branching brownian motion, described by measure-valued processes, is studied. By applying the strong branching property, the Markov property and the expression of the generator are derived for the process ...

Random laminations and multitype branching processes
Electronic Communications in Probability, 2011 We consider multitype branching processes arising in the study of random laminations of the disk. We classify these processes according to their subcritical or supercritical behavior and provide Kolmogorov-type estimates in the critical case corresponding to the random recursive lamination process of [1].

On a Maximum Sequence in a Critical Multitype Branching Process
The Annals of Probability, 1992 The \(p\)-type (positively regular, non-singular) critical branching process, \(\{Z_ n\}\), is considered. Let \(v\) be the right eigenvector of the mean matrix corresponding to the eigenvalue 1 and let \(Y_ n\) be \(Z_ n\cdot v\), which is a martingale. It is the maximum sequence of this martingale that is studied. Specifically if \(M_ n=\max\{Y_ j: 0\
