We report fully relativistic molecular-dynamics simulations that verify the appearance of thermal equilibrium of a classical gas inside a uniformly accelerated container. The numerical experiments confirm that the local momentum distribution in this system is very well approximated by the Jüttner function-originally derived for a flat spacetime-via the Tolman-Ehrenfest effect. Moreover, it is s...

1. Previous studies on the forewing stretch receptors (FSRs) of locusts have suggested that feedback from these receptors during flight contributes to the excitation of depressor motoneurones and reduces the duration of depolarizations in elevator motoneurones. We have investigated these proposals by measuring the timing of FSR activity relative to depressor activity and by examining the effect...

The implementation of a low-cost FATEK PLC-based three-floor lift system is described in this study. Elevator systems are critical for vertical mobility buildings, and their control methods have been revolutionized by the use programmable logic controllers (PLCs). To motion lift, we DC geared motor. In example, push buttons used to direct elevator desired floor. scenario, ladder diagram program...

24 Accurate control of grip force during object manipulation is necessary to prevent the 25 object from slipping, especially to compensate for the action of gravitational and inertial 26 forces resulting from hand/object motion. The goal of the current study was to assess whether 27 the control of grip force was influenced by visually-induced self-motion (i.e., vection) which 28 would normally ...

Group elevator scheduling is an NP-hard sequential decision-making problem with unbounded state spaces and substantial uncertainty. Decision-theoretic reasoning plays a surprisingly limited role in fielded systems. A new opportunity for probabilistic methods has opened with the recent discovery of a tractable solution for the expected waiting times of all passengers in the building, marginalize...

OBJECTIVE Introducing message prompts at the 'point-of-choice' (POC) between stairs and escalators increases stair choice in 'public-access' settings (e.g. malls). For nationwide campaigns, plentiful POCs appear needed. We audited the availability of POCs in public-access settings across England. METHODS Boundaries for 25 urban areas (population=6,829,874) were verified using Ordinance Survey...
