The epidemic threshold theorem with social and contact heterogeneity
(SPIE-INT SOC OPTICAL ENGINEERING, 2008-03-17)
The threshold theorem of an epidemic SIR model was compared when infectious and susceptible individuals have homogeneous mixing and heterogeneous social status and when individuals of random networks have contact heterogeneity. ...
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. ...
Leptospirosis risk around a potential source of infection
(SPIE-INT SOC OPTICAL ENGINEERING, 2015-01-01)
Leptospirosis is a bacterial zoonosis with world distribution and multiform clinical spectrum in men and animals. The etiology of this disease is the pathogenic species of Leptospira, which cause diverse manifestations of ...
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 ...
Parameter estimation of a predator-prey model using a genetic algorithm
(2010-01-01)
This paper presents the parameter estimation of a biological system with real data extracted from literature, and different model structures: Lotka-Volterra model (basic predator-prey model) and saturation predator-prey ...
Modeling, simulation and rapid prototyping of an unmanned mini-helicopter
(2006-01-01)
This paper presents a rapid software prototyping environment (RSPE) for the design, simulation, and real-time implementation of a control system for an autonomous mini-helicopter. The software prototyping environment ...
Design of a control system for interferometric fringe stabilization system with remote access
(SPIE, 2013-11-18)
Stability in a fringe pattern is a necessary condition in interferometric processes, such as holography, and not always is enough the use of passive stabilization systems, like holographic tables, in particular, when ...
Soap film analysis by speckle interferometer
(SPIE-INT SOC OPTICAL ENGINEERING, 2003-01-01)
In this paper a soap film is characterized by using a speckle interferometer. The arrangement consists of a double-exposure specklegram obtained through a double-aperture system, by introducing a wedge in front of one ...
Combining fuzzy and PID control for an unmanned helicopter
(IEEE Communications Society, 2005-01-01)
This paper reports the synthesis of a controller for the X-Cell mini-helicopter. It is developed on basis of the most realistic mathematical model actually availble ([1]). A combined control structure is proposed: Mamdani ...
