The development and expansion of labyrinth walking in corrections has signaled a milestone in the treatment of offenders, particularly those incarcerated for substance abuse-related offenses. In this article we describe the evolution of the labyrinth walking program from its inception highlighting: curriculum development and refinement, evidence-based and program evaluation findings. Methods us...

The paper cryptanalyses the stream cipher Labyrinth a cipher recently proposed by Bo Lin and Simon Shepherd Given only known bits of keystream the bit key of Labyrinth is recovered in under a second of computation using a DEC Alpha

Introduction Piano Key weirs (PKWs) are a hydraulically attractive alternative to linear overflow weirs, increasing the unit discharge at the unregulated spillway inlet for similar heads and spillway widths. This advantage, allowing for operation of dam reservoirs on elevated supply levels thus providing an increased retention volume, is a result of the non-linear nature of PKWs being folded ba...

Cracks often arise in an aeroengine labyrinth disc, which endanger flight security. Non-destructive testing (NDT) must been carried out in the labyrinth disc during the aeroengine working time. In situ detecting cracks in the labyrinth disc, the probe need pass through three layers narrow holes of aircraft skin, engine shell and outlet duct. Ultrasonic, radiography and liquid penetrant inspecti...

This paper analyzes laminar viscous fluid flow through interstices in order to properly design the labyrinth seals and improve the volumetric efficiency of the turbomachines. The theoretical study and hydrodynamic modeling of the threedimensional flow inside the labyrinth was made using a CFD application ANSYS Fluent, on different labyrinth geometries. There were determined: the flow spectrum, ...
