Modified method of characteristics with maneuver overload impact analysis on water hammer effects
Journal of Physics: Conference SeriesAbstract In response to the complex mechanisms of water hammer effects in aircraft fuel pipeline systems under maneuver overload conditions and the constraints of existing Method of Characteristics (MOC) analysis, this study proposes a modified MOC method (MMOC). By introducing an overload acceleration vector decomposition model within a

Percussive Augmenter of Rotary Drills for Operating as a Rotary-Hammer Drill [PDF]
A percussive augmenter bit includes a connection shaft for mounting the bit onto a rotary drill. In a first modality, an actuator percussively drives the bit, and an electric slip-ring provides power to the actuator while being rotated by the drill ...

Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Journal of Religious History, EarlyView.Abstract The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

‘A Sort of Armed Argument’: Ireland's Civil War of Words
History, EarlyView.Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.

SPACE-TIME CONSERVATION METHOD APPPLIED TO NUMERICAL SOLUTION OF WATER HAMMER EQUATIONS
TASK Quarterly, 2011 This paper is devoted to the space-time conservation (STC) method and its application to a water hammer in steel pipelines. The STC method, due to its numerical properties, in particular its high accuracy, can be an interesting alternative to traditional numerical methods, especially when dealing with problems where the numerical errors have the ...
