EXPONENTIAL GROWTH AND DECAY RATE ALGORITHM
INTRODUCTION TO THE EXPONENTIAL DECAY
In mathematics, exponential decay narrates the procedure of decreasing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed. The exponential decay formula is useful in a miscellany of real-world implications, most principally for trailing inventory that’s used frequently in the same aggregation (like food for a school cafeteria) and it is especially useful in its potential to rapidly assess the long-term cost of use of a product over time.
The decay rate algorithm is a sequence of uninterrupted steps concerning effective animal regeneration, bloodlines, and mortality in human capability. It is trying to en glace those traits in humans and in other animals, to make effective hybrids without there being any side effects such as hosts taking over in the subject. The result was the “Decay Rate Algorithm,” an equation relating to cell regeneration and human mortality. The Decay Rate Algorithm is a combination of the real science found in the Gompertz Equation and the Reliability Theory of Aging and Longevity.
WHAT ACTUALLY THE GOMPERTZ MODEL IS?
The Gompertz model is distinguished and widely used in many facets of biology. It has been frequently used to describe the growth of animals and plants, as well as the number or volume of bacteria and cancer cells. Numerous parametrizations and re-parametrizations of differing functionality are found in the literature, whereof the Gompertz-Laird is one of the more frequently used. Discussing and presenting many of the re-parametrizations and some parameterizations of the Gompertz model, which we divide into Ti (type I)- and W0 (type II)-forms is also as major as understanding it.
In the W0-form a starting-point parameter, defining birth or hatching value (W0), replaces the inflection-time parameter (Ti). We also propose novel “unified” versions (U-versions) of both the traditional Ti-form and a clarified W0-form. In these, the growth-rate constant represents the relative growth rate instead of merely an unspecified growth coefficient. We also present U-versions where the growth-rate parameters return absolute growth rate (instead of relative).
The new U-Gompertz models are exceptional cases of the Unified-Richards (U-Richards) model and thus belong to the Richards family of U-models. As U-models, they have a set of parameters, which are proportional across models in the family, without conversion equations. The refinement is simple, and may seem trivial, but are of great importance to those who study organismal growth, as the two new U-Gompertz forms give easy and fast access to all shape variables needed for describing most types of growth adherent to the shape of the Gompertz model.
THE HISTORY
From the 1920s the cumulative Gompertz-Makeham model also expeditiously became the most favored in fields other than that of human mortality, for example in forecasting the increase in demand for goods and services, sales of tobacco, growth in railway traffic, and the demand for automobiles. Wright was the first to propose the Gompertz model for biological growth, and the first to apply it to biological data was probably Davidson in his study of body-mass growth in cattle. In 1931 Weymouth, McMillin, and Rich reported the Gompertz model to eminently describe the shell-size growth in razor clams, Siliqua patula, and Weymouth and Thompson reported the same for the Pacific cockle, Cardium Corbis. Soon, researchers began to fit the model to their data by regression, and over the years, the common Gompertz model became a favorite regression model for many types of growth of organisms, such as dinosaurs, e.g. birds, e.g. and mammals e.g. including those of marsupials, e.g. The Gompertz model is also frequently applied to model growth in the number or density of microbes growth of tumors and the survival of cancer patients.
I hope that you’ll be able to easily understand the titled subject through this article, we will be coming up with more interesting articles on Mathematical modeling and genetics for enthusiasts. Thank you.
