The misunderstanding about the water-clearing and nitrifying bacteria

Fish farming is a science. With the popularization of the idea of scientific fish farming, people pay more and more attention to fish tank ecosystem, biochemical filtration, biological filter material, nitrifying bacteria, and so on, they are trying to create a comfortable living environment for the fishes, so that they can show us the most beautiful side. But in the forum for a long time, found a lot of fish friends on the understanding of the existe

ZOJ 3598 Spherical Triangle (Calculate geometry spherical triangle inner angles and)

Title Link: http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=4682As everybody knows, the sum of the interior angles of a triangle on a plane are always the degree. But that's not true when the triangle are on spherical surface. Given a triangle on a spherical surface, which is asked to calculate the sum of the interior angles of the triangle.Formally, given the 3 vertex of the triangle. They is co

Swarm intelligence algorithm-simulation of the optimal route behavior of slime bacteria in finding food

Watching a video yesterday (Http://www.tudou.com/programs/view/4QmfLMMBZBg) is about a strong network built by the slime bacteria looking for food. The following figure Through the observation of the behavior of sticky bacteria. I would like to use a distributed swarm algorithm to simulate the behavior of slime to achieve the optimal path of search. At present, simple behavior simulation is realized.

Calculation of the spherical distance between two points on the Spherical Surface

Calculation of the spherical distance between two points on the Spherical Surface In fact, this is a very simple problem. The reason why I proposed it and made a solution today is that when I discussed the project yesterday, it is difficult for lead to calculate the distance between two points on the Earth's sphere. It is actually a very simple Three-dimensional Geometric calculation. On the other hand, e

I hope the red fermented bacteria/fermented feed/feed fermentation/bio-fermented feed/bio-fermentation function feed/bio-feed why so red?

Feed raw material price rises, labor cost increases, hog raising cost further is pulled high, the breed enters the high cost time, in the industry already is indisputable fact. How to reduce the cost of feeding has become the industry's most concerned topic. Farmers can only improve feed utilization rate and reduce feed waste in case the feed price cannot be left or right. The use of fermented feed is one of the effective methods to improve feed utilization.Hope that red functional bio-fermented

Studies have found that many of the germs are transmitted by chopsticks. According to tests, a pair of unclean chopsticks may carry tens of t

Swarm Intelligence algorithm--the optimal route behavior simulation of slime bacteria searching for food 2

After searching some data, it is found that the theoretical support has cellular automata, in which the diffusion-limited condensation model in fractal theory is more appropriate to the network of slime bacteria. Adjusted over and over again. Now buy a network of slime bacteria. As shown in figure: The first diagram is a simulation process The second figure is the enlargement of the final graph There a

Food residue and bacteria in the mouth are not easy to remove

Keep your teeth clean, your mouth healthy, and your toothbrush is a must. However, how to choose a good toothbrush? In this issue, I would like to share with you my choice of toothbrush standards.The brush head is short and narrow. Short and narrow brush head can be flexible in the mouth to rotate, can reach all parts of the tooth (especially the molar near the side of the cheek), not easy to leave a dead corner. The American Dental Association recommends that adult toothbrushes should be: Brush
