Análisis y Oportunidades de Mejora en E-commerce
Año a año, según el índice de ventas online aumenta el consumo de losclientes en medios de compra no presencial.Las tendencias mundiales indican que los consumidores están cambiandosus patrones de compra, prefiriendo cada vez mas los canales de compra on-line, por sobre las tiendas físicas y Chile, no está al margen de esta tendencia.Por lo tanto, cada vez cobra más importancia contar con plataformas webque hagan la compra expedita. Cerca de un 15% de las ventas se hacen deforma online en Chile. Entoncesm aún queda mucho por mejorar y proba-blemente, en la a medida que mejore la calidad de servicio en la venta onlineeste porcentaje irá aumentando.

Robot localization in a mapped environment using Adaptive Monte Carlo algorithm
Robot localization in a mapped environment using Adaptive Monte Carlo algorithm
Localization is the challenge of determining the robot's pose in a mapped environment. This is done by implementing a probabilistic algorithm to filter noisy sensor measurements and track the robot's position and orientation. This paper focuses on localizing a robot in a known mapped environment using Adaptive Monte Carlo Localization or Particle Filters method and send it to a goal state. ROS, Gazebo and RViz were used as the tools of the trade to simulate the environment and programming two robots for performing localization.

Modélisation de l’évacuation d’un immeuble en cas d’incendie
When an issue arises in a building, people's evacuation is a recurring challenge. We wondered whether we could make a realistic simulation of people’s evacuation based on a simple physical model. First, we elaborated this model and then we simulate the people’s comportment on MATLAB. We could conclude that our simulation is enough to describe the general comportment of people.

Diversity and Social Capital in the U.S:  A tale of conflict, contact or total mistrust?
Diversity and Social Capital in the U.S: A tale of conflict, contact or total mistrust?
This paper explores the relationship between ethnic fractionalization and social capital between 1990-2005. First, using data from 1990, 1997 and 2005 we test for time differences in the impact of ethnic fractionalization on social capital. Subsequently, we examine U.S. data for evidence consistent with the proposed outcomes in the conflict, contact, or hunker-down theses discussed in Putnam (2007). Putnam (2007) examines what happens to “trust" or “social capital" when individuals of different ethnicity are introduced into social, political and/or economic groups over time. Using an instrumental variable (IV) estimator, we find little evidence of heterogeneity in the impact of ethnic fractionalization on social capital over our period of analysis. In addition, using both fixed effect and IV estimators, we reject the contact hypothesis, but find evidence consistent with the outcomes predicted in both the conflict hypothesis and Putnam’s hunker-down hypothesis, in inter-ethnic relations. Due to data limitations, we are unable to test directly which of these two thesis are more relevant for the U.S experience. However, we provide suggestive evidence in support of the conflict hypothesis over the hunker-down hypothesis. Our results suggest that between 1990-2005, as communities in the U.S became more diverse, there was a tendency for social capital to decline.

Geometria de superfícies isentrópicas
Geometria de superfícies isentrópicas
A dinâmica topológica de inversões geométricas foi estudada em [6]. O espa ̧co de parâmetros das medidas de Markov com suporte no atrator do sistema é um aberto de R3 folheado por superfícies de nível compactas definidas pela entropia métrica: superfícies isentrópicas [7]. Neste artigo abordaremos o aspecto geométrico dessas superfícies. Em particular, classificaremos suas geodésicas e pontos umbílicos.
