Entire or partial loss of function in the shoulder, elbow or wrist represent an increasingly common ailment connected to a wide range of injuries or other conditions including sports, occupational, spinal cord injuries or strokes. A general treatment of these problems relies on physiotherapy procedures. An increasing number of metallic materials are continuously being developed to expect the requirements for different engineering applications including biomedical field. Few constructive models that can involve intelligent materials are analyzed to establish the advantages in usage of shape memory elements mechanical implementation. The shape memory effect, superelasticity and damping capacity are unique characteristics at metallic alloys which demand careful consideration in both design and manufacturing processes. The actual rehabilitation systems can be improved using smart elements in motorized equipments like robotic systems. Shape memory alloys, especially NiTi (nitinol), represent a very good alternative for actuation in equipments with moving dispositive based on very good actuation properties, low mass, small size, safety and user friendliness. In this article the actuation and the force characteristics were analyzed to investigate a relationship between the bending angle and the actuation real value.

RESUMEN Las investigaciones sobre las fortificaciones en el norte de Nueva España son escasas. Además, aunque hay escritos aislados sobre algunas fortificaciones, no se han realizado estudios que de manera integral hagan un seguimiento de cada recinto fortificado. El Camino Real de Tierra Adentro, motivo de este escrito, alberga un inmenso testimonio de los diversos procesos históricos que en su tendido se forjaron. Dicho testimonio se traduce en una gama de bienes patrimoniales que fueron construidos individual y colectivamente a lo largo de tres siglos. Su transformación da cuenta del conocimiento heredado de técnicas o modelos constructivos, y de estrategias de ocupación, lo cual le imprime un sentido de permanencia en el tiempo.PALABRAS CLAVESfortificaciones, Camino Real de Tierra Adentro, presidio de El PasajeABSTRACTInvestigations about the fortifications of northern New Spain are scarce. Besides, even though there are isolated writings on some types of fortification, no studies have been carried out that comprehensively track each fortified enclosure. The Camino Real de Tierra Adentro, the reason for this article, has left us an immense testimony of various historical processes forged in it. This testimony translates into a range of patrimonial assets that were built individually and collectively over the course of three centuries. Its transformation gives an account of the inherited knowledge of techniques or constructive models, and of the occupation strategies, which impress on it a sense of permanence in time.KEYWORDSfortifications, Camino Real de Tierra Adentro, El Pasaje prison

This paper investigates the algorithmic dimension spectra of lines in the Euclidean plane. Given any line L with slope a and vertical intercept b, the dimension spectrum sp ( L ) is the set of all effective Hausdorff dimensions of individual points on L. We draw on Kolmogorov complexity and geometrical arguments to show that if the effective Hausdorff dimension dim ( a , b ) is equal to the effective packing dimension Dim ( a , b ), then sp ( L ) contains a unit interval. We also show that, if the dimension dim ( a , b ) is at least one, then sp ( L ) is infinite. Together with previous work, this implies that the dimension spectrum of any line is infinite.
