A new PLSGP (potential smokers-light smokers-persistent smokers-giving up smokers-potential smokers) model with birth and death rates on complex heterogeneous networks is presented. Using the mean-field theory, we obtain the basic reproduction number R0 and find that basic reproduction number for constant contact is independent of the topology of the underlying networks. When R0＜1, the smoki ...

A number of modules have been designed and developed by the paper writer,
using LabVIEW for numerical analysis to the design of a virtual interactive
graphical user interface (GUI) software to solve QR Factorization, and LU Factorization. The focus of this study is to provide virtual
models to solve systems of linear Equations by using QR Factorization,
LU methods. The significant finding reached by the researchers, is that the
virtual model can be used to solve any systems of linear equation. B...

Test problem simulations are presented of the matrix equation, D = BF,
equivalent to least squares data fitting, where the matrices are rectangular
with D and F being experimental data. The chosen application is finding fractions
of secondary structures of proteins from circular dichroism (CD) spectra
employing singular value decomposition, SVD, to obtain the matrix B and its
pseudo- reciprocal. In practice the
first step of the analysis is to select the reduced noise representation ...

Calculation of electron correlation energy in molecules involves a very important computational effort, even in the simplest cases. Nowadays, using the new parallel libraries (PETSc and SLEPc) and MPI, we can resolve this calculation faster and with very big molecules. This result is a very important advance in chemical computation.
