Mathematical Models of Distribution of Sediment Concentration

Journal of Hydraulic Engineering, 2000
Mathematical models have been developed that can completely describe the distribution of sediment concentration from the channel bed to the water surface. These models can be used to estimate the mean (depth-averaged) sediment concentration by a quick, point sampling in river engineering practice.

A mathematical theory of size distributions in tissue culture

Journal of Mathematical Biology, 1983
A model for growth of a tissue culture consisting of cell clumps is given. A set of equations for following the size distribution of clumps is used to determine total biomass accumulation. Existence and uniqueness of a solution to the equations is proved, and estimates of the biomass growth is given in a number of situations.

Optimization by Vector Space Methods

, 1968
From the Publisher: Engineers must make decisions regarding the distribution of expensive resources in a manner that will be economically beneficial. This problem can be realistically formulated and logically analyzed with optimization theory. This book

A mathematical analysis of the DCT coefficient distributions for images

IEEE Transactions on Image Processing, 2000
Over the past two decades, there have been various studies on the distributions of the DCT coefficients for images. However, they have concentrated only on fitting the empirical data from some standard pictures with a variety of well-known statistical distributions, and then comparing their goodness of fit.

Multiplication of Distributions in Mathematical Physics

2016
We expose a mathematical method that permits to treat calculations in form of multiplications of distributions that arise in various areas of mathematical physics, starting with an analysis of the famous Schwartz impossibility result (1954), then a construction of products of distributions, with examples and references of use in various domains of ...

The Unreasonable Effectiveness of Mathematics in the Natural Sciences (reprint)

, 1960
There is a story about two friends, who were classmates in high school, talking about their jobs. One of them became a statistician and was working on population trends. He showed a reprint to his former classmate. The reprint started, as usual, with the

Basics in Mathematics and Distributed Algorithms

2012
In this chapter, we study briefly the mathematical foundations for building self-organizing mechanical systems. First, we discuss diffusion dynamics in a physical continuum, and then introduce reaction-diffusion systems that generate spatial patterns, and cellular automaton models which behave like those continuous systems in discrete state, space and ...

Mathematical Modeling of Cell Distribution in Alginate Microbeads

Materials Science Forum, 2005
Alginate is one of the mostly used hydrogels for cell entrapment aimed for applications in food industry, environmental engineering, pharmacy and biomedicine. One of the major parameters affecting cell viability and activity is cell distribution inside the immobilization matrix.

Mathematics and Gender: Heterogeneity in Causes and Consequences

, 2014
We exploit an institutional reduction in the costs of acquiring advanced high school mathematics to assess the causes and consequences of fewer girls choosing advanced mathematics.
