Structure parameter inference approach for endocrine feedback control
SPINA is software for determining constant structure-parameters of endocrine feedback control systems from hormone levels obtained in vivo. The first version of this cybernetic approach allows for evualuating the functional status of the thyroid gland, i.e. thyroid's secretory capacity (GT or SPINA-GT) and sum activity of peripheral deiodinases (GD or SPINA-GD).

The software for solving special problems of mathematics and physics
The project "FD-Method For Solving PDEs" contains the software for solving the nonlinear Klein-Gordon equations (see www.arxiv.org/abs/1203.5979 for more detail). The project "Infinite systems of matrix equations" consists in developing algorithms and software for solving systems of matrix equations. In the present version the project allows one to solve an infinite system of matrix equations which arises in the theory of stability preserving structural transformations of systems of second-order ODEs (see http://arxiv.org/abs/1204.1814). The project "Nonlinear Stourm-Liouville Problems with Distribution Potentials" is developed for solving nonlinear Sturm-Liouville problems with integrable potentials including Dirac delta function. The numerical-analytical method used in the project is called the FD-method. It was first proposed by Professor V.L.Makarov in 1991.To learn more about the problems of such type and the FD-method see, for example, http://arxiv.org/abs/1112.2540.

Matrix c++ library solving any linear algebra problems
HASEM is a c++ template library, it can be easily configure as a expression template. HASEM solves any linear equation of any kind, it might be homogenous/none homogenous, compute the inverse of square/none square matrices, find LU decomposition, find determinant and rank of matrices, calculate the characteristic polynomial of matrices, find the eigenvalues and eigen vectors and so on. HASEM uses many methods, therefore, you are not limited to just one method, you have the choice to define your desire method as default one. With over 200 member functions and over 40 none member functions HASEM is almost able to solve any linear algebra problems. HASEM support multidimensional as well, you can mix up your multidimensional matrix with other matrices with different size, and apply all operations on them as well.It's possible to save the computed matrix into files, and when required read it from files and load the data into matrices. It is also very easy to add your extension to HASEM.
