First, available storm rainfall records are used for dimensionless–intensity–duration (DID) curve development, then, the suitable theoretical probability distribution function (PDF) is obtained for the ADMR record series, which provides return periods' identification for a given set of risk values, ...
The Intensity-Duration-Frequency Curve, or IDF Curve, is used in the fields of meteorology and hydrology to estimate the peak rainfall rate, or intensity, during a storm event. The peak rainfall rate experienced varies with the duration of the storm and the location of the storm on the earth...
then you will need to develop your own IDF curve. 03:38 To do that, you will need to input several return periods. 03:42 For example, these three IDF curves represent three different return periods: 03:53 It is important to understand that a higher return period is not a multiple...
由于最近在编译一个esp32的项目时,由于改动频繁,项目经常clean或者fullclean,或者重配menuconfig,然后重新编译,结果次次都出现下面的问题: ccache: error: Failed to create temporary fileforesp-idf/libsodium/CMakeFiles/__idf_libsodium.dir/libsodium/src/libsodium/crypto_box/curve25519xchacha20poly1305/box_curv...
使用BLE 配网时,为了允许服务发现,必须在开始配置之前初始化 mDNS。 protocomm_security 一共有3个选项,这里只说protocomm_security1 Curve25519 key exchange + AES-CTR encryption/decryption 蓝牙技术联盟UUID 蓝牙核心规范制定了两种不同的UUID,一种是基本的UUID,一种是代替基本UUID的16位UUID。
So far, the literature has not given an answer to the question if and how a single and parsimonious IDF structure closely related to the three-parameter IDF curve could be developed based on the scale invariance approach for reliably expressing rainfall intensity over a large range of durations,...
主要是为了方便了解实际代码层面的配网协议是什么样的,所以文档记录的基本上是代码片段。 ESP-IDF的版本是V5.0 使用SoftAP 传输时,为了允许服务发现,必须在开始配置之前初始化 mDNS。 protocomm_security 一共有3个选项,这里只说了protocomm_security1 Curve25519 key exchange + AES-CTR encryption/decryption ...

XGBoost Learning Curve Log Loss 第二张图表示分类错误率: XGBoost Learning Curve Classification Error 从第一张图来看,似乎有机会可以进行Early Stop,大约在20到40轮迭代时比较合适。 从第二张图可以得到相似的结果,大概在40轮迭代时效果比较理想。 在XGBoost中进行Early Stop XGBoost提供了在指定轮数完成后提前停...
