Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

1. 什么是关联数组？ 关联数组是一种数据结构，通过自定义键名（非整数索引）来存储和访问数据。每个键名对应一个值，类似于字典或映射表。其核心特点是： 键名自定义：可以是字符串、数字等（取决于语言）。 键值对存储：数据以 键 => 值 形式组织。

The TS-4x8 V-Band Array Antenna is a 57 to 67 GHz planar antenna with a bore-sight gain of min. 14 dBi (18 dBi without feed losses) measured at V-connector at 60 GHz (simulated antenna gain ...

Add a description, image, and links to the associative-array topic page so that developers can more easily learn about it.

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

Abstract: The operation of an array of coupled oscillators underlying the associative memory function is demonstrated for various interconnection topologies (cross-connect and star-coupled). Three ...

Abstract: The success of SQL, NoSQL, and NewSQL databases is a reflection of their ability to provide significant functionality and performance benefits for specific domains, such as financial ...
