Mathematical analysis of a two-dimensional population model of metastatic growth including angiogenesis
2D structured populations semigroup asymptotic behavior malthus parameter
2010/12/6
Angiogenesis is a key process in the tumoral growth which allows the cancerous tissue to impact on its vasculature in order to improve the nutrient’s supply and the metastatic process. In this paper, ...
Mathematical justification of spectral/covariance techniques: On the example of arc detection
arcing faults Fourier transform power spectrum
2010/9/13
Detecting arcing faults is an important but difficult-to-solve practical problem. Many existing methods of arc detection are based upon acquiring a signal that is proportional to current and then maki...
Mafia (also called Werewolf) is a party game. The participants are divided into two competing
groups: citizens and a mafia. The objective is to eliminate the opponent group. The game consists of two ...

Mathematical and numerical analysis of a model for anti-angiogenic therapy in metastatic cancers
Anticancer therapy modelling Angiogenesis Structured population dynamics
2010/12/8
We introduce and analyze a phenomenological model for anti-angiogenic therapy in the treatment
of metastatic cancers. It is a structured transport equation with a nonlocal boundary condition de-scrib...

Probabilistic metric space Mathematical expectation
2010/9/14
The purpose of this article is to study the mathematical expectation of probabilistic metric space and by using the method of mathematical expectation to study the fixed point theorem of Banach in the...
A mathematical approach to solve data envelopment analysis models when data are LR fuzzy numbers
Data envelopment analysis fuzzy mathematical programming
2010/9/15
data envelopment analysis is a linear programming methodologie that has been widely used to evaluate the performance of a set of decision-making units. It requires crisp input and output data. However...
A note on smoothing mathematical programs with equilibrium constraints
Mathematical programs with equilibrium constraints；smoothing approach
2010/9/15
Mathematical programs with equilibrium constrains (MPECs) in which the constraints are defined by a parametric variational inequality are considered. Recently, nonlinear programming solvers have been ...
A global mathematical investigation of a predator-prey model
predator-prey plane differential system
2010/4/8
We construct a global bifurcation diagram of the plane differential system $$ {l} \dot x = x(1-x)-x y/(a+x^2), \dot y = y(\delta-\beta y/x), x(t)>0, y(t)>0, a>0, \delta>0, \beta>0, $$ which describes ...
A mathematical model to reproduce the wave field generated by convergent lenses
convergent lenses focal phenomena conformal mapping normed monoid
2009/1/9
Geometric optic gives a good approximation to obtain the focus generated by
convergent lenses in the case that their physical characteristics do not give aberrations.
However, some refractive device...

Guardian of the genome, p53 gene, and its partners that form
the complex network involved in apoptosis and cell cycle arrest, is put
under investigation. Some relevant mathematical models are descri...
An avian influenza mathematical model
Avian influenza mathematical model stability analysis
2010/9/13
The present mathematical model deals with the dynamics of human infection by avian influenza both in birds and in humans. Stability analysis is carried out and the behaviour of the disease is illustra...
