For mathematical modeling and analysis, valid assumptions are made keeping in view the following: • The mathematical model should be compatible with the prototype structure within a reasonable degree of accuracy. • The mathematical model has to be such that it can be analysed with the available mathematical tools.

Chapter 1 Markov Chains - University of Massachusetts …

This chain originated in physics as a model for two cubical volumes of air connected by a small hole. In the mathematical version, we have two "urns," i.e., two of the exalted trash cans of probability theory, in which there are a total of N balls. We pick one of the N balls at random and move it to the other urn. Let X


Age is not just a number—Mathematical model suggests ...

The fifth component of the eco-evolutionary model describes senescence in its two forms: reproductive senescence and actuarial senescence (Figure 1e). The reproductive senescence was modeled by multiplying the linear model for fecundity by the gonadosomatic index (GSI, = (gonad weight/total tissue weight) × 100) for the year class in question.

Age is not just a number—Mathematical model suggests ...

1 INTRODUCTION. Senescence is considered a fundamentally fitness decreasing trait, and its presence and role in natural populations remains an unsolved problem in biology (Monaghan et al., 2008; Nussey et al., 2013; Selman et al., 2012).Senescence is often described as age-dependent increase in natural mortality (known as actuarial senescence) and age …

Mathematical modeling of heat recovery from a rotary kiln ...

Then a mathematical model was developed for a new heat recovery exchanger for the plant. It was determined that 5% of the waste heat can be utilized with the heat recovery exchanger. The useful heat obtained is expected to partially satisfy the thermal loads of 678 dwellings in the vicinity through a new district heating system.

balls and white balls (e.g. 3 black and 3 white in urn 1, and 2 black and 2 white in urn 2). In this case, P(Wj1) = P(Wj2) = 1 2 so P(W) = 2, but we have already determined that the strategy given above does better. In the second case, we suppose that one of the urns has (strictly) more white balls than black balls.

Modelling of the High-Energy Ball Milling Process

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.
