Self-similarity of trailing vortices Self-similarity of trailing vortices
Trailing vortices have been repeatedly shown to exhibit a remarkably robust selfsimilarity independent of the Reynolds number and upstream boundary conditions. The collapse of the inner-scaled circulation profiles of a trailing vortex has even been previously demonstrated for the cases of highly unsteady and turbulent vortex systems, as well as for vortices which were incompletely developed. A ...
متن کاملImproving PARMA trailing
Taylor introduced a variable binding scheme for logic variables in his PARMA system, that uses cycles of bindings rather than the linear chains of bindings used in the standard WAM representation. Both the HAL and dProlog languages make use of the PARMA representation in their Herbrand constraint solvers. Unfortunately, PARMA’s trailing scheme is considerably more expensive in both time and spa...
متن کاملFrom 'trailing wives' to the emergence of a 'trailing husbands' phenomenon: Retirement migration to rural areas
Migration and gender studies have focused on economically active heterogeneous couples and traditionally highlight a dominant male role in migration decision-making. The female partner is commonly portrayed as a ‘trailing wife’ or ‘trailing mother’ with the move found to have a negative effect on her employment prospects. Much less is known about if or how the balance of power shifts between hu...
متن کاملTrailing Analysis for HAL
The HAL language includes a Herbrand constraint solver which uses Taylor’s PARMA scheme rather than the standard WAM representation. This allows HAL to generate more efficient Mercury code. Unfortunately, PARMA’s variable representation requires value trailing with a trail stack consumption about twice as large as for the WAM. We present a trailing analysis aimed at determining which Herbrand v...
متن کاملTrailing the Path to Preventive Oncology
Cancer is the most dreadful of all the illnesses. Etiology lies in a genetically predisposition modified with environmental exposure. Around one third of cancer deaths are due to the 5 leading behavioral and dietary risks: high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco use, alcohol use. Tobacco use is the most important risk factor for cancer causing ar...
