The genus Polianthes belongs to the subfamily Agavoideae of the Asparagaceae family formerly known as Agavaceae. The genus is endemic to México and comprises about 15 species, among them is Polianthes tuberosa L. The aim of this work was to…

Sparse Wireless Sensor Networks (SWSN) have been proposed to explore and gather data
from harsh environments. Exploration has been focused on finding optimal paths to obtain knowledge
about the environment while data gathering has mainly been oriented to obtain raw…

The observed expansion of the red lionfish, Pterois volitans (Linnaeus, 1758), in the Caribbean represents one of the most rapid marine fish invasions in the history. The invasion rate of this top predator has resulted in a marked negative effect on local fish populations in the Caribbean by impacting local biodiversity. The main aim of this work was to conduct the…

This thesis explores how an agent can autonomously learn about its environment
just by interacting with it. This is not an easy task, since traditional
machine learning algorithms strongly depend on the user's intervention to define
the data to…

Recientemente se han desarrollado nuevos materiales orgánicos para ser empleados como dispositivos fotovoltaicos y sistemas láser. Para optimizar el funcionamiento de estos dispositivos es necesario tener un conocimiento detallado de los procesos que determinan su eficiencia como lo son: fotogeneración…

In this article we study the retrospective inverse problem. The retrospective inverse problem consists of in the reconstruction of a priori unknown initial condition of the dynamic system from its known final condition. Existence and uniqueness of the solution is…

Research studying effective planning and optimization in the vehicle routing field has increased tremendously in the last few decades. Advances in technology and computational power have encouraged researchers to consider various vehicle routing problem types and constraints, and to experiment…

One does not have to be a fierce advocate of dialectics to consider the claim that the exercise of dystopic imagination may represent a necessary stage to think a better world. If it is good to know the worst, that does not…
