Researchers at the National Institute for Occupational Safety and Health studied mining accidents that involved a worker entangled in, struck by, or in contact with machinery or equipment in motion. The motivation for this study came from the large number of severe accidents, i.e. accidents resulting in a fatality or permanent disability, that are occurring despite available interventions. Acci...

Human operators often diagnose industrial machinery via anomalous sounds. Given the new advances in field of machine learning, automated acoustic anomaly detection can lead to reliable maintenance machinery. However, deep learning-driven methods require an extensive amount computational resources prohibiting their deployment factories. Here we explore a machine-driven design exploration strateg...

In a variety of engineering disciplines, including the mechanical, aerospace, and energy industries, study nonlinear dynamics vibration analysis rotating machinery has become increasingly important. many applications, turbines, engines, compressors, pumps, is essential for both performance safety entire system. Nonlinearities, on other hand, add intricate dynamic behaviours phenomena into these...

Wearable Computing is an emerging discipline that has attracted attention from researchers and industry alike [Boeing 1996]. The combination of augmented-reality, mobility, and hands-free operation promises valuable computer support in areas with currently low deployment of computer technology. Examples include assembly and maintenance of complex machinery like airplanes and vehicles, quality c...

Telomere clustering is required for the homologous recombination events that maintain chromosome ends in cells relying on alternative lengthening of telomeres (ALT). New data demonstrate that damage signaling at telomeres, a likely step in activating maintenance mechanisms, induces directional movement and synapsis driven by the machinery responsible for recombination in meiosis.

“Our [power] plant no longer needs imported equipment or skills. ...Recalling the past, [veteran machinery maintenance man] Lu said, ‘Under imperialist control, all important technical data was withheld from Chinese workers. ...Today all the technology is in our hands. And we run our plant ten times better than the imperialists!’” “Shanghai’s biggest power plant—then and now,” China Reconstruct...

Polycomb-group (PcG) and Trithorax-group proteins together form a maintenance machinery that is responsible for stable heritable states of gene activity. While the best-studied target genes are the Hox genes of the Antennapedia and Bithorax complexes, a large number of key developmental genes are also Polycomb (Pc) targets, indicating a widespread role for this maintenance machinery in cell fat...

The maintenance of a production line is becoming more important with the development demanding higher operational efficiency and safety in industrial system. However, often operates under dynamically environmental conditions scheduling also very factor for line. First, this paper proposes an integrated data-driven model that coordinates planning decisions to solve problem parallel-series degrad...

Modern design methods for both rolling stock and machinery aim to automate processes as much possible. Cab engine driver should run the train, not be involved in its maintenance, maintenance crew is required know advance all failures on a particular cab. But addition standard train operation, there are number of issues that affect safety reliability operational equipment. These include heating ...

Abstract We consider an operator of machinery with deteriorating efficiency, facing the problem optimally timing either a minor (maintenance) investment or major (replacement) under price uncertainty. If maintenance is chosen, efficiency will deteriorate more slowly, and replacing later still possible. The optimal decision rule expressed in form thresholds for long-run prices, indicating that i...
