Automated quantification of plant water transport network failure using deep learning
… change, threaten plants through hydraulic failure. This hydraulic failure is caused by the formation of embolisms which block water flow in a plant's xylem conduits. By tracking these failures over time, vulnerability curves (VCs) can be created. The creation of these curves is laborious …

Real-time bandwidth encapsulation for IP/MPLS Protection Switching
… guarantee the protection of voice traffic during network failure. Since voice calls have a time constraint of 50 ms within which the traffic must be recovered, a real-time bandwidth management scheme is required. Such bandwidth allocation scheme that prioritizes voice traffic will ensure that the …

Survivability Analysis of Two Specific 16-Node, 24-Link Communication Networks
A highly survivable communication network is desirable, as service disruption is usually not tolerated. In this thesis we mainly investigate and discuss the survivability of two specific communication networks, termed topology 1 and 2, under usual network failures. The survivability of the networks …

Scheduling real-time messages in packet-switched networks
In a real-time network, it is not practical to have one centralized scheduler manage all the network resources, e.g., the transmission links and buffer space. Instead, each node has its own scheduler which manages the various resources at that node. In an ideal case, the schedulers are completely …

Optical sensing as a means of monitoring health of multicomputer networks
… can allow the multicomputer to detect imminent failure in a particular section of the interconnection network due to damaging strain. This detection method allows the rerouting of critical data before data link failure occurs. This thesis investigates the implementation of the extrinsic …

Fiber-Based ATM Computer Network Performance and Survivability Issues under Soft Failure Conditions
… research a suspected "gray" area in computer network performance that might exist between the network's optimum performance and complete network failure was investigated. Changes in performance were studied as seen by the application layer of the network as attenuation was introduced at the …

In-Network Processing For Mission-Criticalwireless Networked Sensing And Control: A Real-Time, Efficiency, And Resiliency Perspective
… we consider application QoS requirements in in-network processing (INP). In this dissertation, we explore the potentials of two INP methods, packet packing and network coding, on improving network performance while satisfying application QoS requirements. We find that not only can these two …

Machine Learning–Based Detection of Network Failures in Core Network Cellular Data
The increasing complexity of mobile networks and the large volume of traffic data generated by multiple network elements make it difficult for Mobile Network Operators (MNOs) to accurately identify operational irregularities and reliably distinguish true network failures from normal network …

Evaluation of Zinc Toxicity Using Neuronal Networks on Microelectrode Arrays: Response Quantification and Entry Pathway Analysis
Murine neuronal networks, derived from embryonic frontal cortex (FC) tissue grown on microelectrode arrays, were used to investigate zinc toxicity at concentrations ranging from 20 to 2000 mM total zinc acetate added to the culture medium. Continual multi-channel recording of spontaneous action …

Improved methods for fast system reliability analysis through machine-learning-based surrogate models
… of different regions of infrastructure networks is crucial to post-event decision making. The specific problem of determining the probability that two nodes in an infrastructure network are disconnected given the edge failure probabilities is known as the two-terminal connectivity …

Unraveling the Reconfiguration Dynamics of Silver Nanowire Networks under Electrothermal Stress
… including a shaky supply chain and brittleness. Networks of silver nanowires show many advantages over ITO, but they suffer from problems with durability. In this work, we focus on electrothermal instability and provide new insights into the electrothermal drivers of silver nanowire network …

Congestion avoidance in internet protocol (IP) networks
… slow convergence of routing protocols after a network failure becomes a growing problem. During failures, the forwarding paths in a network change, the forwarding tables in the routers need to be updated. During the update process, transient link overflows may occur if it is not performed in an …

Determinação de Chaveamento para Recomposição do Serviço em Redes de Distribuição de Energia Elétrica em Média Tensão Através de Métodos Baseado em Parâmetros de Sensibilidade
The reconfiguration of a distribution network is a change in its topology, aiming to provide specific operation conditions of the network, by changing the status of its switches. It can be performed regardless of any system anomaly. The service restoration is a particular case of reconfiguration …

The influence of mobile payments on the choices and functionings of Micro and Small Enterprise (MSE) entrepreneurs in Lesotho
… However, these entrepreneurs face issues such as network failure, withdrawal amount limits and security risks while using mobile payments. Value of the study: The study contributes to the existing ICT4D and mobile payments literature in Lesotho by discussing the influence of mobile payment through …

Diagnose network failures via data-plane analysis
Diagnosing problems in networks is a time-consuming and error-prone process. Previous tools to assist operators primarily focus on analyzing control plane configuration. Configuration analysis is limited in that it cannot find bugs in router software, and is harder to generalize across protocols …

Framework for pedestrian walking behaviour recognition to minimize road accident
… wireless communication has critical issues with network failure, and these issues significantly affect the communication system. Thus, the framework involved two modules for pedestrian walking behaviour classification in a vehicle-to-pedestrian (V2P) context is proposed. In the methodology, this …

Efficient Enforcement of Security Policies in Distributed Systems
… PDP also represents a single point of failure. In case of the failure of the centralised PDP, all resources in the system may cease to function. The efficient distribution of enforcement mechanisms is therefore key in building large scale policy managed distributed systems. Moving from …
