    Features a unique program to estimate the power spectral density. The spectrum containing all significant Details is calculated from a time series model. Model type as well as model order are determined automatically from the data, using statistical criteria. Robust estimation algorithms and order selection criteria are used to obtain reliable results. Unlike in FFT analysis, where the experimenter has to set the amount of smoothing of the raw FFT, the right level of detail is assessed using the data only.

  • distmesh

    matlab有限元網格劃分程序 DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed description of the program is provided in our SIAM Review paper, see documentation below. One reason that the code is short and simple is that the geometries are specified by Signed Distance Functions. These give the shortest distance from any point in space to the boundary of the domain. The sign is negative inside the region and positive outside. A simple example is the unit circle in 2-D, which has the distance function d=r-1, where r is the distance from the origin. For more complicated geometries the distance function can be computed by interpolation between values on a grid, a common representation for level set methods. For the actual mesh generation, DistMesh uses the Delaunay triangulation routine in MATLAB and tries to optimize the node locations by a force-based smoothing procedure. The topology is regularly updated by Delaunay. The boundary points are only allowed to move tangentially to the boundary by projections using the distance function. This iterative procedure typically results in very well-shaped meshes. Our aim with this code is simplicity, so that everyone can understand the code and modify it according to their needs. The code is not entirely robust (that is, it might not terminate and return a well-shaped mesh), and it is relatively slow. However, our current research shows that these issues can be resolved in an optimized C++ code, and we believe our simple MATLAB code is important for demonstration of the underlying principles. To use the code, simply download it from below and run it from MATLAB. For a quick demonstration, type "meshdemo2d" or "meshdemond". For more Details see the documentation.

    Fire and Fury。 This article is about the 2018 book. For other uses, see Fire and Fury (disambiguation). The title refers to a quote by Trump about the conflict with North Korea. The book became a New York Times number one bestseller.Fire and Fury: Inside the Trump White House is a 2018 book by Michael Wolff which Details the behavior of U.S. President Donald Trump and the staff of his 2016 presidential campaign and White House. The book highlights descriptions of Trump's behavior, chaotic interactions among senior White House staff, and derogatory comments about the Trump family by former White House Chief StrategistSteve Bannon. Trump is depicted as being held in low regard by his White House staff, leading Wolff to state that "100% of the people around him" believe Trump is unfit for office.[1] Reviewers generally accepted Wolff's portrait of a dysfunctional Trump administration, but were skeptical of many of the book's most controversial claims.

  • MSP430G2553

    DESCRIPTION The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 μs. The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16- bit timers, up to 24 I/O capacitive-touch enabled pins, a versatile analog comparator, and built-in communication capability using the universal serial communication interface. In addition the MSP430G2x53 family members have a 10-bit analog-to-digital (A/D) converter. For configuration Details see Table 1. Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values, and then process the data for display or for transmission to a host system.

  • 基于多尺度字典的圖像超分辨率重建

    Reconstruction- and example-based super-resolution (SR) methods are promising for restoring a high-resolution (HR) image from low-resolution (LR) image(s). Under large magnification, reconstruction-based methods usually fail to hallucinate visual Details while example-based methods sometimes introduce unexpected Details. Given a generic LR image, to reconstruct a photo-realistic SR image and to suppress artifacts in the reconstructed SR image, we introduce a multi-scale dictionary to a novel SR method that simultaneously integrates local and non-local priors. The local prior suppresses artifacts by using steering kernel regression to predict the target pixel from a small local area. The non-local prior enriches visual Details by taking a weighted average of a large neighborhood as an estimate of the target pixel. Essentially, these two priors are complementary to each other. Experimental results demonstrate that the proposed method can produce high quality SR recovery both quantitatively and perceptually.

  • python爬蟲獲取大量免費有效代理ip--有效防止ip被封

    以后再也不用擔心寫爬蟲ip被封,不用擔心沒錢買代理ip的煩惱了 在使用python寫爬蟲時候,你會遇到所要爬取的網站有反爬取技術比如用同一個IP反復爬取同一個網頁,很可能會被封。如何有效的解決這個問題呢?我們可以使用代理ip,來設置代理ip池。 現在教大家一個可獲取大量免費有效快速的代理ip方法,我們訪問西刺免費代理ip網址 這里面提供了許多代理ip,但是我們嘗試過后會發現并不是每一個都是有效的。所以我們現在所要做的就是從里面提供的篩選出有效快速穩定的ip。 以下介紹的免費獲取代理ip池的方法: 優點:免費、數量多、有效、速度快 缺點:需要定期篩選 主要思路: 從網址上爬取ip地址并存儲 驗證ip是否能使用-(隨機訪問網址判斷響應碼) 格式化ip地址 代碼如下: 1.導入包 import requests from lxml import etree import time 1 2 3 2.獲取西刺免費代理ip網址上的代理ip def get_all_proxy():     url = 'http://www.xicidaili.com/nn/1'     headers = {         'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36',     }     response = requests.get(url, headers=headers)     html_ele = etree.HTML(response.text)     ip_eles = html_ele.xpath('//table[@id="ip_list"]/tr/td[2]/text()')     port_ele = html_ele.xpath('//table[@id="ip_list"]/tr/td[3]/text()')     proxy_list = []     for i in range(0,len(ip_eles)):         proxy_str = 'http://' + ip_eles[i] + ':' + port_ele[i]         proxy_list.append(proxy_str)     return proxy_list 1 2 3 4 5 6 7 8 9 10 11 12 13 14 3.驗證獲取的ip def check_all_proxy(proxy_list):     valid_proxy_list = []     for proxy in proxy_list:         url = 'http://www.baidu.com/'         proxy_dict = {             'http': proxy         }         try:             start_time = time.time()             response = requests.get(url, proxies=proxy_dict, timeout=5)             if response.status_code == 200:                 end_time = time.time()                 print('代理可用:' + proxy)                 print('耗時:' + str(end_time - start_time))                 valid_proxy_list.append(proxy)             else:                 print('代理超時')         except:             print('代理不可用--------------->'+proxy)     return valid_proxy_list 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 4.輸出獲取ip池 if __name__ == '__main__':     proxy_list = get_all_proxy()     valid_proxy_list = check_all_proxy(proxy_list)     print('--'*30)     print(valid_proxy_list) 1 2 3 4 5 技術能力有限歡迎提出意見,保證積極向上不斷學習 ———————————————— 版權聲明:本文為CSDN博主「彬小二」的原創文章,遵循 CC 4.0 BY-SA 版權協議,轉載請附上原文出處鏈接及本聲明。 原文鏈接:https://blog.csdn.net/qq_39884947/article/Details/86609930
