Mean free path and Mean free time01:22

Mean free path and Mean free time

5.2K
Consider the gas molecules in a cylinder. They move in a random motion as they collide with each other and change speed and direction. The average of all the path lengths between collisions is known as the "mean free path."

Behavior of Gas Molecules: Molecular Diffusion, Mean Free Path, and Effusion

31.4K
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target. At room temperature, a gaseous molecule will experience billions of collisions per second. The mean free path is the average distance a molecule travels between collisions. The mean free path increases with decreasing pressure; in general, the mean free path for a gaseous molecule will be...

Numerical Calculations

1.2K
In engineering applications, the representation of the numerical value is critical. Presenting or reporting the answer is one of the essential parts of engineering practices. Numerical calculations are performed using handheld calculators or computers since numerically accurate answers are always preferred.
The solution to a problem is obtained using different methods. While manually solving algebraic symbols is one of the most common methods, the graphical method is often preferred. Computers...

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Interference: Path Lengths01:10

Interference: Path Lengths

2.2K
Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

まとめ

幼い子供は数のタスクに空間記憶を使用するが、この関連は年齢とともに薄れる。象徴的な数のスキルは、非象徴的な能力から発達し、空間スキルから直接発達するわけではない。

科学分野:

  • 認知心理学
  • 発達心理学
  • 教育工学

背景:

  • 空間能力は認知発達に不可欠である。
  • 空間スキルと数値処理の間の相互作用を理解することは、早期数学教育の鍵となる。
  • デジタルツールは、子供の認知機能を研究するための新しい方法を提供する。

主な方法:

  • スマートフォンアプリケーションを使用して、空間短期記憶、空間ワーキングメモリ、非象徴的比較、象徴的比較の4つの課題を実施した。
  • 平均年齢6.41歳の541人の子供からデータを収集した。
  • 関連性と年齢効果を探るために、共分散分析と統一モデル分析を実行した。

結論:

  • 空間能力、特に短期およびワーキングメモリは、初期の数値処理、特に幼い子供において直接関与している。
  • 数値タスクに対する空間戦略への依存は、子供の年齢とともに減少する。
  • 象徴的な数値表現は、初期の発達において空間能力への直接的な関連を持つのではなく、非象徴的な表現の上に構築されるように見える。
