3d). This result indicate that the phosphorescence property is directly associated with the conformation of C1. Furthermore, the theoretical calculation was carried out to evaluate the energy levels of C1 at different temperatures. As expected, its lowest-lying triplet states changed with conformation...
The arms and shoulders move in circular motion; as the rope follows a circular motion,(55)momentum (力量,势头)can be provided by rotating the wrists.(56)by pushing off from the toes just(57)enough to allow the rope to pass under your feet. Some physical educators(58)that rope skipping ...
Kinetic or potential energy associated with the motion or position of an object gravity A force of attraction between objects that is due to their masses. gravitational energy Potential energy that depends on the height of an object electric energy ...
Notably, with solar prices far below alternatives, higher learning rates have a small effect on diffusion. Overall, in 72% of the simulations done for robustness testing, solar makes up more than 50% of power generation in 2050. This suggests that solar dominance is not only possible but ...
The sound that the ball makes when it bounces also requires a slight energy loss; but friction—a force that resists motion when the surface of one object comes into contact with the surface of another—is the principal culprit where energy transfer is concerned. Of particular importance is ...
Zhu et al. (2010) studied the heat transfer performance of a wall with high thermal mass in zero-energy buildings. Their results indicate that it is most suitable to be applied in areas with large temperature differences between the day and night as well as between indoors and outdoors. In...
In our numerical study, however, we employ a simpler and more realistic waveform, and aim at verifying the robustness of the approach with respect to the investigation method and the control parameters, establishing that the advantage is not limited to reductions in drag, but extends to savings ...
Wearable technology is emerging as a solution for various bio-mechanic and health-metric applications. Solar photovoltaic energy is a viable supplemental power source that can reduce battery size requirements in wearables. This study outlines the conside
