The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

A Queuing Network Model for Solving Facility Layout Problem in Multifloor Flow Shop

open access: yesIEEE Access, 2022
Based on comprehensive consideration of stochastic factors and the system performance, we presented an integrated queuing network model (IQNM) to effectively optimize the facility layout of the multi-floor flow shop (MFFS).

‘Enthusiasts’ and ‘Fanatics’: The Decembrists as a Case Study in French Influence on Russian Culture, Emotions and Thought

open access: yesHistory, EarlyView.
Abstract Participants in Russia's 1825 Decembrist uprising against the Tsarist regime were, quite literally, a case study in French cultural influence upon Russia. This is particularly true as it relates to Russia's emotional cultures. Although this has not, traditionally, been the primary focus of historical analysis of this event (in Soviet or ...

Analysis of wafer sojourn time in dual-arm cluster tools with residency time constraint and activity time variation

open access: yes, 2010
When scheduling cluster tools under wafer residency time constraints, wafer sojourn time in a processing module should be carefully controlled such that it is in a permissive range.

Comparison of multi-state Markov models for cancer progression with different procedures for parameters estimation. An application to breast cancer

open access: yesEpidemiology, Biostatistics and Public Health, 2013
Background: the knowledge of sojourn time (the duration of the preclinical screen-detectable period) and screening test sensitivity is crucial for understanding the disease progression and the effectiveness of screening programmes.

A Repairable System Supported by Two Spare Units and Serviced by Two Types of Repairers

open access: yesJournal of Statistical Theory and Applications (JSTA), 2021
We study a one-unit repairable system, supported by two identical spare units on cold standby, and serviced by two types of repairers. The model applies, for instance, to ANSI (American National Standard Institute) centrifugal pumps in a chemical plant ...

Sojourn Time in an Union of Intervals for Diffusions [PDF]

open access: yesMethodology and Computing in Applied Probability, 2012
We give a method for computing the iterated Laplace transform of the sojourn time in an union of intervals for linear diffusion processes. This random variable comes from a model occurring in biology concerning the clustering of membrane receptors. The way used hinges on solving differential equations.

Commercial treaties and political transformation in Sulu and Southeast Asian littorals, c. 1830–1840

open access: yesAsia‐Pacific Economic History Review, EarlyView.
Abstract This article re‐examines an economic treaty concluded between Spain and the Sulu Sultanate in 1836. Analysing the Tausug (Jawi) and Spanish treaty versions alongside archival sources from Spain, the Philippines, and England, it traces the impact of indigenous agency beyond the formal signatories on economic and political transformations ...
