(cont.) Packing/Covering problems, we prove upper and lower bounds on the adaptivity gap depending on the dimension. We also design polynomial-time algorithms achieving near-optimal approximation guarantees with respect to the adaptive optimum. Finally, we prove complexity-theoretic results regarding optimal adaptive…

"En zonas semiáridas del centro de México la sobreexplotación de pastizales ha ocasionado severa reducción de su productividad. Su fisonomía se caracteriza por espacios abiertos con presencia de costras biológicas del suelo. Aunque este tipo de paisaje es representativo de…

"En el Altiplano Potosino, la especie vegetal utilizada para la producción de mezcal es Agave salmiana. La industria mezcalera, que carece de sistemas de explotación basados en el conocimiento biológico de la especie que utiliza como materia prima, puede causar…

Increasingly, knowledge-based tasks such as new product development and market research are being conducted by geographically dispersed teams. Early evidence from knowledge-based view of the firm and geographically dispersed work literatures suggests that at least four kinds of knowledge gaps---transactive…

Currently, people involved in protection against disaster situations must
make the decisions about preparing and executing evacuation plans for potential
causes of disaster. Hence, it would be desirable to develop a system capable
of obtaining and analyzing evacuation plans…

Knowledge-based Cascade-correlation is a neural network algorithm that combines inductive learning and knowledge transfer (Shultz & Rivest, 2001). In the present thesis, this algorithm is tested on several real-world and artificial problems, and extended in several ways. The first extension…

In order to close the gap that exists between the research areas of mathematics anxiety and mathematics learning, this study examined cognitive, metacognitive, and affective aspects of mathematics anxiety as well as students' mathematics performance and competence. One hundred and…

The first edition of the CASPUR Summer School for Advanced Computing took place from August 29 to September 9th, 2005, in the ENI meeting center in the beautiful surroundings of Castel Gandolfo’s lake. The school has been invented to further…
