overflow

问题 can't really figure out why this error RuntimeWarning: overflow encountered in exp is showing up. The function I'm trying to implement is: Id = lambda t_u, yp: Is * (np.exp((Vin(t_u) - L*yp)/(n_Ut*Ut)) - 1.0) with values: Vin = lambda t: Vo * np.sin(2*np.pi*w*t) L = 50e-3 # 50 mH Vo = 5 # 5 V w = 50 # 50 Hz Is = 1e-9 # 1 nA Ut = 25e-3 # 25 mV n_Ut = 1.0 The function Id is part of a ODE that I'm trying to solve with Runge-Kutta-Method. EDIT: Methoden\Serien\6>python circuit.py Traceback (most

问题 I am trying to show a dropdown menu on hover, but I also have to apply an overflow: hidden to the parent element. The result is my dropdown, even though absolutely positioned, isn't visible (because of the overflow: hidden). I reproduced the problem there: http://plnkr.co/edit/2rbaISwvzuKhyPEFpBKD?p=preview (you can hit Edit/Code edit to see the full source code) (small sample) #block-paddle-menu-display-first-level .menu_wrapper.level-2 { position: absolute; visibility: hidden; } #block

问题 Let's me try to explain the issue. Assume we have 2 flex box boxOrange and boxPurpule who share the full width of a container and stretch to the height of this one. Due to their min-width of 400px , these flex box warp in 'column' on small screen (demonstration in Example 1). If one of the box contain too much content, the box is scrollable (like boxOrange in the demonstration of Example 2). The issue is when their is scrollable content on small screen. I would like the boxOrange keep 50%

问题 On my website I have a flexbox container with an image in it (fixed width and height) and a text beside it(no fixed width). How can I prevent the text being from being higher than the image and show a scrollbar when it's higher. Please see also code snippet below. Example: .recipe-article{ display: flex; } .recipe-img { flex: 0 0 265px; } .recipe-text{ flex: 1; max-height: 265px; } <article class="recipe-article"> <img class="recipe-img" src="" width="265" height="265"> <section class="recipe

问题 I'm studying buffer overflow and solving some wargames. There was a problem that all of the stack memory above the buffer is set to 0 except return address of main, which will be: buffer [0000000...][RET][000000...] and I can overwrite that RET. So I found some hints for solving this problem. It was to use LD_PRELOAD. Some people said that LD_PRELOAD's value is in somewhere of stack not only in environment variable area of stack. So I set LD_PRELOAD and search it and found it using gdb. $

问题 I want to have a text that overflows in another div, so I found and used this answer from another question at Stackoverflow. The problem is that only plain text is displayed; links, bold/italics and paragraphs are ignored. Here is the same jsfiddle from the answer, but with added html tags. How do i get to display them? Code: var currentCol = $('.col:first'); var text = currentCol.text(); currentCol.text(''); var wordArray=text.split(' '); $.fn.hasOverflow = function() { var div= document
