Cotton Production ModelARSA new process-based cotton model, CPM, has been developed to simulate the growth and development of upland cotton (Gossypium hirsutum L.) throughout the growing season with minimal data input. CPM predicts final cotton yield for any combination of soil, weather, cultivar and sequence of management actions. |

The k-nearest neighbor (k-NN) technique is a non-parametric technique that can be used to make predictions of discrete (class-type) as well as continuous variables. The k-NN technique and many of its derivatives belong to the group of .lazy learning algorithms.. It is .lazy., as it passively stores the development data set until the time of application; all calculations are performed only when estimations need to be generated. |

LOX Calculator for Fasted Channel CatfishAquaculture Systems Research Unit
A review of scientific literature concerning channel catfish Ictalurus punctatus respiration resulted in the development of an interactive computer model for estimating the volume of oxygen consumed by a given fasted channel catfish biomass. Entry of ten variables provides estimates of oxygen gas consumption with respect to time and biomass, the liquid oxygen equivalent of that volume, liquid oxygen expense, and the ratio of liquid oxygen expense to gross revenue for a s |

Formula CalculatorFormosan Subterranean Termite Research
A program written in visual basic for calculations in mass spectrometry. The program will calculate the possible formulas for a given molecular weight. The formulas are calculated based on known chemical connectivities and not from random atom combinations. Because of this, all generated formulas will be actual compounds. |
