We construct a website to explain how Gaussian mixture models can be optimized using the expectation maximization algorithm. Previous free, online material on this process has been extremely limited. All sources surveyed failed to entirely describe our identified criteria for an in-depth description and useful visualizations. After surveying a variety...

The indicated sum of a real scalar and a real or imaginary
vector is called a scator. Either the scalar part or the vector part
may be null. Scators generalize the complex variable to n-space.
The algebra of scators is not generally associative under multiplication
but the commutative and distributive...
Discusses the advantages of drip irrigation and how it can help growers use water efficiently. Covers basic concepts related to components and design as well as management considerations such as placement of the tape, timing and rates, maintenance, and adjustments to fertilizer rates.
Drip irrigation is the slow, even application of low-pressure water to soil and plants using plastic tubing placed near the plants’ root zone. It is an
alternative to sprinkler or furrow methods of irrigating crops. Drip irrigation can be used for crops with high or low water demands.
