Stochastic order inequalities for systems with standby units and parallel-series configurations

Journal of Inequalities and Applications
Abstract In this paper, we first consider stochastic orderings of lifetimes of series and parallel systems with cold standby units. The strategy is to find out whether the reliability of a series or parallel system improves when standby units are installed on the components or on the subsystem.

A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Multivariate hazard orderings of discrete random vectors [PDF]

The task of comparing two random vectors with respect to some multivariate stochastic ordering usually involves an infinite number of comparisons. Dyckerhoff and Mosler (1997) proved that, when the random vectors have finite supports, this task, for some

A Novel Two‐Stage Flexible Flow Shop Batch Scheduling Model for Grinding Workshops

Naval Research Logistics (NRL), EarlyView.
ABSTRACT The growing need for data storage in data centers has increased the demand for mechanical hard disks due to their low cost and high reliability. Aluminum substrates are the most popular base plates for mechanical hard disks because of their high hardness and low cost.

Consistent Collaborative Vehicle Utilization

Networks, EarlyView.
ABSTRACT Carriers are often reluctant to collaborate with other carriers in delivering goods to customers despite potential cost reductions. A durable collaboration requires attention to more aspects. Carriers typically wish to remain competitive, unconstrained by the collaboration, increasing profits by attracting new customers and withholding ...

Self‐Service and Home Delivery Combined: Coordinating the Route of a Mobile Parcel Locker With the Delivery Tasks of Its Human Driver

Networks, EarlyView.
ABSTRACT In response to the increasing volume of parcels, last‐mile delivery innovations are exploring the integration of multiple delivery modes. The most prominent examples are delivery vans that, next to being the base for the delivery tasks of their human drivers, also function as mobile launching platforms for drones or autonomous delivery robots.

Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Parabolic Littlewood-Paley inequality for a class of time-dependent operators of arbitrary order, and applications to higher order stochastic PDE

, 2015
In this paper we prove a parabolic version of the Littlewood-Paley inequality for a class of time-dependent local and non-local operators of arbitrary order, and as an application we show this inequality gives a fundamental estimate for the $L_p$-theory of the stochastic partial differential equations.

Development of a Fiber Bundle Cell Framework for Rapid, Reliability‐Based Analysis and Design of Pseudo‐Ductile Thin‐Ply Hybrid Composites

Polymer Composites, EarlyView.
Application of the fiber bundle cell model for design or prediction of pseudo‐ductility. ABSTRACT In this study, we developed and validated a novel fiber bundle cell (FBC) framework to enable rapid, reliability‐anchored design of pseudo‐ductile thin‐ply carbon/glass hybrid composites.
