A Preclinical Multifunctional Capsule Robot with Unified Diagnosis and Targeted Thermal Therapy for Gastrointestinal Diseases. [PDF]

open access: yesAdv Sci (Weinh)
A proof‐of‐concept multifunctional capsule robot integrates diagnostic imaging, magnetic navigation, wireless power transfer, and targeted thermotherapy for gastrointestinal applications. Magnetically guided positioning and stable wireless power enable localized thermal ablation, achieving controlled heating and high cell mortality in vitro.

Managerial perceptions of the personal and career transitions of redundant executives and suvivors of redundancy [PDF]

open access: yes, 2000
Although redundancy became widespread in the late 2Wh century, research was lacking on the perceived impact of redundancy and redundancy management policies on the individual.

A standby-Sparing Technique with Low Energy-Overhead for Fault-Tolerant Hard Real-Time Systems [PDF]

open access: yes, 2009
Time redundancy (rollback-recovery) and hardware redundancy are commonly used in real-time systems to achieve fault tolerance. From an energy consumption point of view, time redundancy is generally more preferable than hardware redundancy.

Low-energy standby-sparing for hard real-time systems [PDF]

open access: yes, 2012
Time-redundancy techniques are commonly used in real-time systems to achieve fault tolerance without incurring high energy overhead. However, reliability requirements of hard real-time systems that are used in safety-critical applications are so ...

Reliability analysis of two-unit cold standby repairable systems under Poisson shock. [PDF]

open access: yes, 2011
This paper analyses the reliability of a cold standby system consisting of two re- pairable units, a switch and a repairman. At any time, one of the two units is operating while the other is on cold standby.

Availability of Parallel Triplicated Redundancy Models With Imperfect Switchovers and Interrupted Repairs

open access: yesIEEE Access, 2018
This paper presents the analysis of the three parallel triplicated redundancy models: model with one active and two standby components, model with one standby and two active components, and model with three active components.

Standby Redundancy Allocations in Series and Parallel Systems [PDF]

open access: yesJournal of Applied Probability, 2011
To enhance the performance of a system, a common practice employed by reliability engineers is to use redundant components in the system. In this paper we compare lifetimes of series (parallel) systems arising out of different allocations of one or two standby redundancies.

Survivors of redundancy: a justice perspective [PDF]

open access: yes, 2007
Organisations in and around Britain continue to restructure and downsize their workforce. Redundancies and reorganisation of staff remains a major aspect of internal organisational change.

A Novel Perspective on Reliable System Design With Erlang Failures and Realistic Constraints for Incomplete Switching Mechanisms

open access: yesIEEE Access, 2023
This study focuses on effectively designing reliable systems. Such systems are capable of withstanding failure events by applying multiple realistic workarounds.
