#### Solving stochastic epidemiological models using computer algebra

(SPIE-INT SOC OPTICAL ENGINEERING, 2011-01-01)

Mathematical modeling in Epidemiology is an important tool to understand the ways under which the diseases are transmitted and controlled. The mathematical modeling can be implemented via deterministic or stochastic models. ...

#### Mathematical model for dengue with three states of infection

(SPIE-INT SOC OPTICAL ENGINEERING, 2012-01-01)

A mathematical model for dengue with three states of infection is proposed and analyzed. The model consists in a system of differential equations. The three states of infection are respectively asymptomatic, partially ...

#### The Critical Proportion of Immune Individuals needed to Control Hepatitis B

(SPIE-INT SOC OPTICAL ENGINEERING, 2016-05-13)

We estimate the critical proportion of immunity (Pc) to control
hepatitis B in Medellin - Colombia, based on a random population survey
of 2077 individuals of 6-64 years of age. The force of infection (Fi)
was estimated ...

#### Dynamics of an Electrochemical Biosensor for the Detection of Toxic Substances in Water

(SPIE-INT SOC OPTICAL ENGINEERING, 2016-01-01)

A proposed analytical method focuses on electrolyte transport to the
electrode of an electrochemical cell. The recombinant Escherichia coli
whole-cell biosensor detects toxicity in water based on a set of
biochemical ...

#### Spatial epidemic patterns recognition using computer algebra

(SPRINGER, 2007-01-01)

An exploration in Symbolic Computational bio-surveillance is showed. The main obtained results are that the geometry of the habitat determines the critical parameters via the zeroes of the Bessel functions and the explicit ...

#### Analysis of the boundary conditions for pyramidal spine fins in extended surface heat transfer

(WITPress, 2014-01-01)

Many studies are conducted for pyramidal spine fins relating to temperature profiles and fin efficiencies. However, it is found that a deeper look into the boundary conditions is required. The conditions at the base are ...

#### Possible topological quantum computation via khovanov homology: D-brane topological quantum computer

(SPIE-INT SOC OPTICAL ENGINEERING, 2009-01-01)

A model of a D-Brane Topological Quantum Computer (DBTQC) is presented and sustained. The model isbased on four-dimensional TQFTs of the Donaldson-Witten and Seiber-Witten kinds. It is argued that the DBTQC is able to ...

#### Computing Tutte polynomials of contact networks in classrooms

(SPIE-INT SOC OPTICAL ENGINEERING, 2013-01-01)

Objective: The topological complexity of contact networks in classrooms and the potential transmission of an infectious disease were analyzed by sex and age. Methods: The Tutte polynomials, some topological properties and ...

#### Optimal control in a model of malaria with differential susceptibility

(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01)

A malaria model with differential susceptibility is analyzed using the optimal control technique. In the model the human population is classified as susceptible, infected and recovered. Susceptibility is assumed dependent ...

#### Two qutrits universal quantum gates from the nine-dimensional unitary solutions of the Yang-Baxter equation

(SPIE-INT SOC OPTICAL ENGINEERING, 2007-04-25)

Using the Kauffman-Lomonaco method, some two-qutrits universal quantum gates are derived from the nine-dimensional unitary solutions of the Yang-Baxter equations associated with algebraic structures like the partial transpose ...
