Anyway, here's our first experiment in creating a bee walkway entrance to a hive that can be videoed under controlled conditions, both for counting and for detecting pollen and mites. It's a partial success from the video point of view, but a failure from the beekeeping point of view, ...
Custom server software written in Python and utilizing the Twisted event-driven network engine was developed to control a feedback loop, run on a Zotac ZBOX HD-AD02 with Ubuntu 11.10 installed. A web interface was constructed using Java and HTML, allowing the user to monitor OD in real time...
A 1 MΩ resistor (Rf) and a 10 pF capacitor (Cf) were placed in the feedback loop of the CSP circuit (Figure 4). The output pulses were recorded on an oscilloscope and saved as CSV files for postprocessing in a program written in python. The sampling frequency of the signal was 10...
如何在python jinja模板中输出loop.counter?我想能够输出当前循环迭代到我的模板。 根据文档: http ://wsgiarea.pocoo.org/jinja/docs/loops.html,有一个loop.countervariables,我正在尝试使用。 我有以下几点: {% for user in userlist %} {{ user }} {{loop.counter}} {% if loop.counter == 1 %...
