In pool (the common American term for pocket billiards), a ball is struck with the end of a long, slender stick (cue), causing it to roll into other balls and knock them into holes (pockets) around the edges of the playing table. A short wall (rail) around the perimeter of the ...
Angles between 30 and 60° from the vertical can be used and 45° tends to be the norm, as it simplifies setting the required wire intersection position with the laser beam centreline, as will be seen shortly. Angles greater than 60° make the latter difficult and angles less than 30° ...
The different enhanced tubes span several generations of development and only one tube specific constant was used to correlate the geometric differences in the tubes (Table 1). Due to the complex interaction of the geometry with the heat transfer mechanisms no effort was made to explain or quantif...
32 is grasped and moved along the X and Y axes, as well as movements therebetween, so that the user is in effect using a combination computer mouse and a joy stick. This permits the cue to be tilted through a variety of angles to effect the necessary "English" to control the pool ...

The samples were incised with a disc cutter 0.5 mm wide, 0.3 mm deep and at angles to the vertical of 0°, 30° and 60°. The active area of the sample is 27 × 27 mm2. The characteristic dimensions of the specimens are given in Table 1 according to the guidelines in Figure 3. ...
These parameters are summarized in Table 1. Table 1. Characteristics of particles used in this research. To perform this study, the entrance and exit slope angles of the pool and riffle were considered 15° and 17°, respectively. This selection is based on both the literature and the ...
Table 3presents a comparative analysis between the improved YOLOv5 algorithm and the original YOLOv5 algorithm using a self-made dataset. The improved YOLOv5 algorithm exhibited superior precision (98.1%) compared to the original YOLOv5 algorithm, with relatively lower values for recall (98.0%) and...

“open”. The other four side boundaries of the wind tunnel were 3 mm-thick steel. The ambient air temperature was 23 °C. The N-heptane (C7H16) fire was set as a flame source (8 cm × 8 cm × 6 cm) at the center axis point of the wind tunnel.Table 2indicates the thermal ...
