Śıntesis de prensiones con “force-closure” para un objeto articulado 3D con 3 eslabones

Este trabajo aborda el problema de la śıntesis de prensiones con “force-closure” para un objeto articulado 3D constituido por 3 eslabones y considerando contactos sin fricción. La superficie de cada eslabón se representa por medio de un conjunto finito de puntos. En primer lugar se presenta una metodoloǵıa por medio de la cual se define el espacio de fuerzas generalizadas generado por fuerzas a...

Designing Semistructured Databases Using ORA-SS Model

Semistructured data has become prevalent with the growth of the Internet. The development of new web applications that require efficient design and maintenance of large amounts of data makes it increasingly important to design “good” semistructured databases to prevent data redundancy and updating anomalies. However, it is not easy, even impossible, for current semistructured data models to cap...

Simple improved con dence intervals for comparing matched proportions 3

For binary matched-pairs data, this article discusses interval estimation of the di erence of probabilities 7 and an odds ratio for comparing ‘success’ probabilities. We present simple improvements of the commonly used Wald con dence intervals for these parameters. The improvement of the interval for the 9 di erence of probabilities is to add two observations to each sample before applying it. ...

Crypt neurons express a single V1R-related ora gene.

Both ciliated and microvillous olfactory sensory neuron populations express large families of olfactory receptor genes. However, individual neurons generally express only a single receptor gene according to the "one neuron-one receptor" rule. We report here that crypt neurons, the third type of olfactory neurons in fish species, use an even more restricted mode of expression. We recently identi...
