Abstract Failure modes of lunar boulders depend both on rheology and the erosion agents acting in surface environment. Here, we address failure their variations at a quasi-global scale (60°N to S). We deploy neural network map total ∼130,000 fragmented (width > ∼10 m) scattered across visually identify dozen different disintegration morphologies corresponding modes. Our findings suggest that...

Modern composite materials based on non-metallic continuous fibres are increasingly used in civil engineering to strengthen building structures. In the strengthening of reinforced concrete (RC) structures, utilisation externally bonded fibre-reinforced polymer (FRP) composites is only up 35% because pilling-off failure mechanism. This problem can be solved using pre-tensioned laminates. Due mor...

The primary goal of this thesis is to study transmission line reactance tweaking, as a mechanism for both post-disturbance control and pre-disturbance resilience enhancement in a transmission network, and develop an optimization framework for evaluating the efficacy of this mechanism in both scenarios. We start by developing a mixed-integer linear programming (MILP) formulation for tracking the...

1. AH5183 (2-(4-phenyl piperidino) cyclohexanol) produced neuromuscular block of slow onset in rapidly stimulated nerve-skeletal muscle preparations of the rat, chicken and cat.2. The neuromuscular block was not antagonized by neostigmine, tetraethylammonium (TEA) or choline. The rate of onset of transmission failure was enhanced by factors which increase the release of acetylcholine.3. It was ...

Amyotrophic lateral sclerosis (ALS) is an unusual, fatal, neurodegenerative disorder leading to the loss of motor neurons. After diagnosis, the average lifespan ranges from 3 to 5 years, and death usually results from respiratory failure. Although the pathogenesis of ALS remains unclear, multiple factors are thought to contribute to the progression of ALS, such as network interactions between g...

This dissertation contains contributions to the management of optical transport networks. The focus is on traffic modeling, analysis of failure mechanism, and the development of a novel semi-automatic network management system. The developed service oriented traffic models serve as input parameters for the network management system and include the special routing of the analyzed services. An ev...

The design of survivable all-optical mesh networks based on bidirectional wavelength division multiplexing (WDM) self-healing rings (SHRs) to supply complete protection against any single link failure requires an efficient solution. This paper proposes a shared protection algorithm called shared protection by concatenated rings (SPCR) using selfhealing capability and a pre-configuration mechani...

Over the last two decades, important advances have been made in explaining some pathophysiological aspects of heart failure with preserved ejection fraction (HFpEF) with repercussions for the successful clinical management of the syndrome. Despite these gains, our knowledge for the natural history of clinical progression from the pre-clinical diastolic dysfunction (PDD) until the final clinical...

Modular redundancy (system replication) and other traditional techniques for fault tolerance in dynamic systems are expensive, and rely heavily — particularly in the case of systems operating over extended time horizons — on the assumption that the error-correcting mechanism (e.g., voting) is fault-free. Herein, we construct redundant dynamic systems in a way that achieves tolerance to transien...
