"Una primer aproximación a un mapa de riesgo de Lavado de activos."

Resumen

Dado que no existe una definción estandar del evento  de riesgo
asociado al lavado de activos, se define el evento, se considera la
naturaleza incierta de las operaciones de lavado de activos, y se
aplican modelos matemáticos que modelar  dicha
naturaleza y  determinar la calificación del riesgo .se  presenta una
metodologìa cuantitativa para obtener la calificación del
riesgo asociado al lavado de activos para: los sectores económicos,
los departamentos y las regiones de Colombia.

THE COOPERATION'S PROBLEM

In this talk we will introduce the idea about the cooperation's problem given by Axelrod. Due to, we are living in world where the individual interest has priority over the group, the central question: what are the conditions that make possible a cooperation?. These conditions involve the iteration prisoner's Dilemma.

  El teorema de Desargues en planos proyectivos.


Resumen

Mediante técnicas modelo-teóricas (construcciones de Hrushovski) exhibiré una construcción de un plano proyectivo donde no se cumple el teorema de Desargues. Luego mostraré cómo se pueden interpretar los planos proyectivos como cierto tipo de categorías y qué significa la (no) validez del teorema de Desargues en éstas.

                              Skew PBW Extensions in algebra and geometry

Abstract

In this talk we present some results about skew PBW extensions which were introduced by Lezama in [1].
These extensions and its localizations include a wide variety of rings and algebras of interest for modern
mathematical physics such as PBW extensions, well known classes of Ore algebras, operator algebras,
di usion algebras, quantum algebras, quadratic algebras in 3-variables, skew quantum polynomials,
among many others.

Stochastic Modeling for Warranty Analysis

Professor Alagar Rangan
Department of Industrial Engineering,
Eastern Mediterranean University



In this talk, we introduce various kind of stochastic models for Warranty Analysis, in particular, extended warranty models. We consider a repairable system subject to two types of failures, minor and major requiring minimal repair and replacement, respectively, as maintenance actions. Extended warranty models for the system that includes a free replacement period and an extended warranty period are analysed. Consumers have several warranty options during the extended warranty period. Explicit expressions for the manufacturer's long run average profit per unit time under these options are obtained. We enlarge the objective function by including the total sales volume. This is done by considering the demand as a displaced log linear function of the product price, fixed warranty period and the extended warranty period.   Numerical illustrations are provided in each case to demonstrate optimal pricing and warranty period.

Electrocardiógrafo Inalámbrico Implementando Módulos de 

Transmisión ZigBee y Paneles Solares

ABSTRACT:
The work is for the design and implementation of an electrocardiograph that deliver cardiac signals wirelessly transmitted using ZigBee technology powered by solar panels using the Labview control software. The importance of this project is to shorten the patient's diagnosis by the doctor during his way to the hospital through the transmission of the cardiac signal wirelessly to be displayed in real time. This will give the doctor more time to analyze the patient before arrival at hospital. Likewise, the solar panel feeding allows the use of irradiation from the sun, to turn the use of an optimum voltage source for powering the circuit and making it more portable electrocardiograph through a feeding system composed of DC / DC converters which adjust the input potential to optimum potential of each subsystem, which in our case requires +/- 5V bias for the acquisition system of the cardiac signal and 3.3V for the wireless transmission stage. Between the results achieved is the design of the power supply together with the cardiac signal obtained analogously pure by LabView Software and wireless transmission by XBee modules.
