I used to think I was good at coding and proud of it. But now I feel that I may need to learn something different in the age of LLM.) 2.

RCS Definition1 The RCS represents an equivalent aperture surface area of the target, which captures a certain amount of incident radiation, and which, if re-radiated isotropically, would produce an equivalent scattered field at the receiver. For 2d target: \[\begin{aligned} \sigma_{2d}=\begin{cases}\lim_\limits{\rho \to \infty}\left[2\pi \rho \frac{S^s}{S^i}\right]\\ \lim_\limits{\rho \to \infty}\left[2\pi \rho \frac{|E^s|^2}{|E^i|^2}\right]\\ \lim_\limits{\rho \to \infty}\left[2\pi \rho \frac{|H^s|^2}{|H^i|^2}\right] \end{cases} \end{aligned}. /post/opencv-gpu/ Sun, 12 Mar 2023 11:10:39 +0800 /post/opencv-gpu/ /post/ielts/ Tue, 17 Jan 2023 10:35:32 +0800 /post/ielts/ /post/dark-mode/ Sat, 05 Nov 2022 00:00:00 +0800 /post/dark-mode/ 暗黑模式介绍 Hugo的even主题在github已经两年没有更新了，我应该是第一个为该主题提供暗黑模式的人（但是由于在手机端还有bug，我暂 /post/zed/ Fri, 14 Oct 2022 00:00:00 +0800 /post/zed/ ZED SDK 安装，功能参考实现链接：ZED SDK Documentations以及Body Tracking Overview。 3D Body Tracking需要CUDA11.1以上 /post/openpose/ Thu, 06 Oct 2022 00:00:00 +0800 /post/openpose/ OpenPose安装及测试环境 OpenPose官网; 参考安装教程; 注意OpenPose与Anaconda不兼容。 测试环境： Ubuntu 20.04和NV /post/linux/ Thu, 12 May 2022 00:00:00 +0800 /post/linux/ Linux Summary windows双系统干净删除Ubuntu 磁盘管理 删除卷。 CMD： 1 2 3 4 5 6 diskpart list disk select disk 0 list partition select partition 1 assign letter = j 管理员权限打开记事本，删除J/ /post/asp/ Tue, 22 Feb 2022 00:00:00 +0800 /post/asp/ info This is a collection of my notes for SUSTech MA208 “Applied Stochastic Processes”, in the spring semester of 2022, based on Professor Zhang Yiying (张艺赢)’s lectures and slides. 毕业压力好大，暂时更新了第一章，可以作为概率论知识汇总作为 /post/introduction/ Tue, 18 Jan 2022 23:09:36 +0800 /post/introduction/ Why I set up such a Personal Website1 Firstly, from the point of view as a student, I think it is necessary for me to build up a private place to record and manage my notes (or some other things) efficiently. In the past three years of my undergraduate student career, I could always dig some interesting ideas almost every day but not always had a chance (or a good
