Multi-sensor classification of tennis strokes

In this work, we investigate tennis stroke recognition using a single inertial measuring unit attached to a player’s forearm during a competitive match. This paper evaluates the best approach for stroke detection using either accelerometers, gyroscopes or magnetometers, which are embedded into the inertial measuring unit. This work concludes what is the optimal training data set for stroke classification and proves that classifiers can perform well when tested on players who were not used to train the classifier. This work provides a significant step forward for our overall goal, which is to develop next generation sports coaching tools using both inertial and visual sensors in an instrumented indoor sporting environment.

A theory of buyer-seller networks

This paper introduces a new model of exchange: networks, rather than markets, of buyers and sellers. It begins with the empirically motivated premise that a buyer and seller must have a relationship, a "link," to exchange goods. Networks - buyers, sellers, and the pattern of links connecting them - are common exchange environments. This paper develops a methodology to study network structures and explains why agents may form networks. In a model that captures characteristics of a variety of industries, the paper shows that buyers and sellers, acting strategically in their own self-interests, can form the network structures that maximize overall welfare.

Enseñanza de la estadística en los grados 3º a 9º

Se desarrolla un taller básico de estadística descriptiva y de probabilidad, con la utilización de mediadores físicos y virtuales, donde se presentan los elementos conceptuales y la aplicación a diversas situaciones cotidianas con algunos comentarios didácticos para orientar el proceso y generar un diálogo acerca de la importancia de la enseñanza de la probabilidad a nivel de básica primaria y secundaria.

Sobre la enseñanza de la geometría: re-creando el arco capaz

Se reporta una investigación realizada con alumnos de 15- 16 años sobre los algoritmos de construcción de un Arco Capaz de segmento y ángulo dado. Se propuso a los alumnos un problema cuya solución óptima es un Arco Capaz de segmento y ángulo dado, y se les requirió luego que construyeran dicho arco utilizando regla, compás y semicírculo. Los alumnos idearon diversas construcciones para el Arco Capaz pero en ningún momento aparece la construcción tradicional de Euclides. Básicamente, la idea que usan los estudiantes para construir el Arco Capaz, es la de obtener un triángulo cualquiera tal que uno de sus ángulos sea el ángulo dado para luego determinar su circuncentro y trazar el Arco.
