Improving network quality-of-service with unreserved backup paths
… for continuous service inexpensively, unreserved backup paths are used in this thesis. While there are no wasted resources using unreserved backup paths, recovery from a failure may not be perfect. Thus, a goal for this approach is to design algorithms that compute backup paths to mask the failure …

Segment backup: datacenter-disaster tolerance for stream processing systems
… tolerance solution called segment backup for stream processing systems. During regular running, segment backup inserts barriers into the normal tuple stream to indicate the backup versions and ensure node-level synchronization of multiple input streams. Additionally, segment backup …

Determination of Backup Alarm Masked Threshold in Construction Noise
… the sounds that need to be heard, such as backup alarms. Therefore, such devices should provide improved signal detection in noise when compared to their passive counterparts. The masked threshold of a vehicular backup alarm was determined for audiometrically normal and non-normal hearers …

TRADEOFF ANALYSIS OF BACKUP POWER GENERATION SOLUTIONS FOR MILITARY BASES
Energy security is becoming increasingly important as the DOD relies on energy to build and project combat power from military installations. Installation energy managers currently ensure uninterrupted power to mission-critical facilities through emergency stand-alone diesel generators. Research …

CheckSync: Transparent Primary-Backup Replication for Go Applications Using Checkpoints
… There could be as few as two in a primary/backup arrangement, or more to reduce the risk of downtime. Each instance starts in the same state, and then advances to new states in the same order. This allows for easy failover to one of the replicas in case the primary machine fails. The use of …

A novel backup protection scheme for hybrid AC/DC power systems
… MVDC system from the wider AC power system via backup - as would be the case for standard AC distribution network assets, where the failure of main protection would require a (usually remote) backup protection system to operate to clear the fault. Very little literature considers remote backup …

Procurement of backup energy supplies for mass transit : Tren Urbano, a case study :
… analysis on options and strategies for procuring backup energy supplies for the Tren Urbano, an urban heavy rail transit system under construction in San Juan, Puerto Rico. The Tren Urbano is designated as a Federal Transit Administration demonstration project because of the unique private role of …

Backup Radio Placement for Optical Fault Tolerance in Hybrid Wireless-Optical Broadband Access Networks
… that to provide full protection while minimizing backup radio deployment cost is NP-complete. We develop an integer linear programming to obtain the optimal solution and two heuristics to reduce computation complexity. To evaluate our heuristic algorithms, we run simulation on real and random …

Aircraft loss-of-control prevention via backup flight control law design and flight envelope protection
… the aircraft loss-of-control problem by adaptive backup flight control law design and flight envelope protection for aircraft with physical damage. In the first part of the study, a backup lateral-directional flight control law for mid-sized transport aircraft with vertical-tail damage is …

Model-Based Dose-Exposure-Response Assessment for Lead and Backup Spectinamide in a Mouse Model of Tuberculosis
… One such lead candidate, spectinamide 1810, and backup spectinamide 1599 have demonstrated excellent efficacy, safety, and drug-like properties in various in vitro and in vivo assessments. The dose-ranging and dose fractionation studies were designed to characterize the dose-exposure-response …

THE IMPACT OF RELIABLE BACKUP CHILDCARE SERVICES ON WORK-LIFE BALANCE AND STRESS LEVELS AMONG WORKING PARENTS
… the relationship between access to reliable backup childcare services, work-life balance, and stress levels among working parents. Building on Arhin’s (2025) research, this study seeks to address limitations in sample diversity and incorporate qualitative methods to gain deeper insight into …

Maintenance practices for emergency diesel generator engines onboard United States Navy Los Angeles class nuclear submarines
… increasing age comes increasing importance of backup generators. In addition to the need for decay heat removal common to all (naval and commercial) nuclear reactors, naval vessels with nuclear reactors also require a backup means of propulsion. All underway Navy nuclear reactors are operated …

A robust optimization approach to network design
… thesis presents a scheme in which a dedicated backup network is designed to provide protection from random link failures. Upon a link failure in the primary network, traffic is rerouted through a preplanned path in the backup network. We introduce a novel approach for dealing with random link …

Reliable peer-to peer multicast streaming
… ideal solution to this problem by introducing a backup tree for the existing base tree. The backup tree is constructed based on parameter such as bandwidth and delay. In case of failure of a node, its children along the tree receive the data from the nodes of backup tree. We present an efficient …

Planning and Team Shared Mental Models as Predictors of Team Collaborative Processes
… team shared mental models (TEAMTSMMs), team backup behaviors, and implicit coordination were tested. This study provides evidence for the mediation effect of similarity of TASKTSMMs between team planning and team backup behaviors, and the mediation effect of team backup behaviors between …

Hardware acceleration of NetApp virtual tape library deduplication algorithm
… of an algorithm used in the deduplication of backup storage data, to compare its performance to a software implementation of the algorithm. This algorithm flags sections of data with identifiers called "anchors". "Anchors" can be compared across versions of backup data, and if "anchors" are …
