Token Jumping in minor-closed classes

, 2017
Given two $k$-independent sets $I$ and $J$ of a graph $G$, one can ask if it is possible to transform the one into the other in such a way that, at any step, we replace one vertex of the current independent set by another while keeping the property of ...

Mechanics of a ski jump

Российский журнал биомеханики, 1998
Построена математическая модель полета лыжника. Учтена полученная на основе решения задачи турбулентного обтекания лыжника воздухом зависимость аэродинамических коэффициентов лобового сопротивления и подъемной силы от угла атаки системы лыжниклыжи. Учтено также влияние на полет ветра, отталкивания от стола отрыва, массы и размера системы лыжник-лыжи ...

Analysis of the beginning of the early flight phase of the ski jump in athletes with different performance levels [Analýza fáze přechodu do letu ve skoku na lyžích u skupin závodníků s různou výkonností]

Acta Universitatis Palackianae Olomucensis. Gymnica, 2011
BACKGROUND: Obtaining a long jumping distance is necessary in order to succeed among the best competitors in the Nordic combined. The body movement during the take-off and early flight is considered to be the most important factor for length of the jump.

Numerical Simulation Research on Aerodynamic Characteristics during Take-Off Phase in Ski Jumping

Applied Sciences
In view of the inability to directly and accurately obtain an athlete’s aerodynamic force during the take-off phase through the wind tunnel test, the athlete’s aerodynamic force and surrounding flow field form under different take-off postures are ...
