The Penetration of Rock by High-speed Water Jets
The effect of pressure, stand-off distance and time on the penetration of sandstones by a 0.84 mm. jet of water was investigated. Pressures ranged up to 9000 lb/in 2 (62 MN/M), stand-off distances to 2 in. (5.08 cm) and time from 0.5 to 30 sec. The effect of using a friction reducing agent was determined. The advantages of allowing the spent jet to escape and not interfere with penetration are ...
متن کاملLightweight enhanced monitoring for high speed networks
In this paper, LEMON, a lightweight enhanced monitoring algorithm based on packet sampling, is proposed. It targets a pre-assigned accuracy on bitrate estimates, for each monitored flow at a router interface. To this end, LEMON takes into account some basic properties of the flows, which can be easily inferred from a sampled stream, and it exploits them to dynamically adapt the monitoring time-...
متن کاملSupermon: A High-Speed Cluster Monitoring System
Supermon is a flexible set of tools for high speed, scalable cluster monitoring. Node behavior can be monitored much faster than with other commonly used methods (e.g., rstatd). In addition, Supermon uses a data protocol based on symbolic expressions (Sexpressions) at all levels of Supermon, from individual nodes to entire clusters. This contributes to Supermon’s scalability and allows it to fu...
متن کاملDynamic Analysis of a High Load, High-speed Actuator for Rock Deformation Experimentation
Experimental investigation of the sliding-velocity dependence of friction in rock is necessary to understand slip instability and earthquake phenomena, but a capability to conduct sliding friction experiments at high normal loads and at earthquake slip rates (1 m/s) must be developed. Velocitydependent friction is ideally studied by imposing step-wise changes in rate of sliding. Velocity steps ...
متن کاملDiscrete wavelet transform for tool breakage monitoring
Detection of tool breakage is of vital importance in automated manufacturing. Various methods have been attempted, and it is considered that the use of discrete wavelet transform (DWT), which is much more efficient and just as accurate wavelet analysis, may provide a realistic solution to the detection of tool breakage in operation. The DWT uses an analyzing wavelet function which is localized ...
