Enhancement of Ultrasound B-Mode Image Quality Using Nonlinear Filtered-Multiply-and-Sum Compounding for Improved Carotid Artery Segmentation

Diagnostics, 2023
In ultrasound B-mode imaging, the axial resolution (AR) is commonly determined by the duration or bandwidth of an excitation signal. A shorter-duration pulse will produce better resolution compared to a longer one but with compromised penetration depth ...

On the Ballooning of Yarn on a Ring Spinning Frame : The Effect of Feeding Speed

Journal of the Textile Machinary Society, 1953
研究目的精紡機のパルーニンゲについての理論酌計算は既になされているが、糸の送り速度を考慮に入れた場合は未だなされていないと思われるから、これを考慮に入れて理論的考察をなしたものである。研究結果精紡機においては糸はある送り速度を以つて走つているので、そのバルーニソグについて論ずる場合、糸の送り速度を考慮に入れなければ、糸の送り速度が小なる場合以外は実際とはなはだ異つたものになる。本論文においては最後に数値計算を以てその差異を示した。
