In addition, we can introduce an incidence angle 𝜃θ; thus, 𝜉0=𝑘sin𝜃ξ0=ksinθ and 𝜅0=𝑘cos𝜃κ0=kcosθ, where 𝑘=𝜔/𝑐k=ω/c, and 𝑐c is speed of sound. Figure 1. A surface with an array of Helmholtz resonators. First, we find the field 𝑃1P1....
Figure 6shows the high-speed video frames of the left-side impacts at t = 14 ms. Similarly to the previous configuration, the angle between a reference line on the helmet and the vertical central axis of the headform illustrated the relative motion between the helmet and the headform for ...
The concentration of dust in the air around a moving vehicle is a variable quantity and depends mainly on the type and condition of the ground, precipitation, wind direction, conditions of vehicle movement (speed, single vehicle or column) and the type of running gear (wheeled or tracked). ...
[75]. Furthermore, the visibility of space is influenced by the movement speed of a pedestrian as well as interactions with other pedestrians and behavior associated with wayfinding [76]. Lighting and weather also impose various influences on visibility. Thus, to account for the inherent ...
The speed of the air at the inlet to the dryer was also measured. Table 2 shows a slight difference (only 0.1 m/s) based on the values of the air temperature at the inlet. In fact, the air was produced by a fan placed before the heater. Therefore, its mass flow rate GAI was ind...
