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…

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…

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…

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…

U.S. copyright law is facing an interesting moment, where technology is far ahead of the law, and where the evolution of law seems to lead nowhere. This article focuses on recent technological evolution and subsequent legal developments, especially the safe…

In June 2008, the Brazilian Interdisciplinary AIDS Association (ABIA) and the Indian NGO SAHARA submitted a joint pre-grant opposition to the patent application of Tenofovir Disoproxil Fumarate in India. This joint action provides a pertinent case model of the potential…

CMOS IC scaling has provided significant improvements in electronic circuit performance.
Advances in test methodologies to deal with new failure mechanisms and nanometer issues
are required. Interconnect opens are an important defect mechanism that requires detailed
knowledge of its physical…

Many asymptotic results for kernel-based estimators were established under some smoothness assumption on density. For cases where smoothness assumptions that are used to derive unbiasedness or asymptotic rate may not hold we propose a combined estimator that could lead to…

BACKGROUND:A variety of definitions of evidence-based practice (EBP) exist. However, definitions are in themselves insufficient to explain the underlying processes of EBP and to differentiate between an evidence-based process and evidence-based outcome. There is a need for a clear statement…
