Analysis of impact of shaft speed and external load on the radial ball bearing lubrication regimes [PDF]
FME Transactions, 2022 Appropriate lubrication of the rolling bearing is needed to lower the friction between the surfaces in mutual contact and their wear. A lubricant should completely separate the rolling elements from the raceways. The values that affect the efficiency and

Dynamics of an inchworm nano-walker [PDF]
, 2006 An inchworm processive mechanism is proposed to explain the motion of dimeric molecular motors such as kinesin. We present here preliminary results for this mechanism focusing on observables like mean velocity, coupling ratio and efficiency versus ATP ...

Most Demanding Passages in Elite Futsal: An Isolated or a Repeat Situation?
Apunts: Educación Física y Deportes, 2020 The main purpose of this research was to examine not only the most demanding passages (MDP) of elite futsal matches through different external load variables: total distance covered (TD), distance covered at high-speed running (HSR), metres covered above

A League-Wide Evaluation of Factors Influencing Match Activity Profile in Elite Australian Football
Frontiers in Sports and Active Living, 2020 Introduction: Accurate interpretation of activity profile data requires an understanding of the variables influencing player movement during matches.Methods: Over 65,000 stints (player rotations) from all 207 matches of the 2018 Australian Football ...

, 1996 We present numerical simulations of the dynamics of two-dimensional Josephson junction arrays to study the mechanism of mutual phase locking. We show that in the presence of an external magnetic field two mechanisms are playing a role in phase locking ...

Stochastic Energetics of Quantum Transport [PDF]
, 2006 We examine the stochastic energetics of directed quantum transport due to rectification of non-equilibrium thermal fluctuations. We calculate the quantum efficiency of a ratchet device both in presence and absence of an external load to characterize two ...

Coupling of Josephson flux-flow oscillators to an external RC load
, 1996 We investigate by numerical simulations the behavior of the power dissipated in a resistive load capacitively coupled to a Josephson flux flow oscillator and compare the results to those obtained for a d.c. coupled purely resistive load.
