Kinematic structure of planar mechanisms addresses the study of attributes determined exclusively by the joining pattern among the links forming a mechanism. The system group classification is central to the kinematic structure and consists of determining a sequence of kinematically and statically independent-simple chains which represent a modular basis for the kinematics and force analysis of the mechanism. This article presents a novel graph-based algorithm for structural analysis of planar mechanisms with closed-loop kinematic structure which determines a sequence of modules (Assur groups) representing the topology of the mechanism. The computational complexity analysis and proof of correctness of the implemented algorithm are provided. A case study is presented to illustrate the results of the devised method.

New motor rehabilitation therapies include virtual reality (VR) and robotic technologies. In limb rehabilitation, limb posture is required to (1) provide a limb realistic representation in VR games and (2) assess the patient improvement. When exoskeleton devices are used in the therapy, the measurements of their joint angles cannot be directly used to represent the posture of the patient limb, since the human and exoskeleton kinematic models differ. In response to this shortcoming, we propose a method to estimate the posture of the human limb attached to the exoskeleton. We use the exoskeleton joint angles measurements and the constraints of the exoskeleton on the limb to estimate the human limb joints angles. This paper presents (a) the mathematical formulation and solution to the problem, (b) the implementation of the proposed solution on a commercial exoskeleton system for the upper limb rehabilitation, (c) its integration into a rehabilitation VR game platform, and (d) the quantitative assessment of the method during elbow and wrist analytic training. Results show that this method properly estimates the limb posture to (i) animate avatars that represent the patient in VR games and (ii) obtain kinematic data for the patient assessment during elbow and wrist analytic rehabilitation.

Las pymes se encuentran envueltas en problemas derivados en distorsiones del sistema empresarial, que incide en la mortalidad de las mismas: la falta de criterios para la toma de decisiones asertivas, lo cual tiene un impacto directo también en la economía en general, y contribuye al aumento del desempleo, la desaceleración económica y, finalmente, a la reducción de la calidad de vida de la sociedad -- El objetivo general de esta investigación consiste en proponer una plataforma de información financiera integral que se constituya en una herramienta de análisis para las pymes en Medellín, Colombia -- Para resolverlo, se desarrollan los siguientes objetivos específicos: 1. Diagnosticar la gestión empresarial en la toma de decisiones -- 2. Describir la información financiera necesaria para la toma de decisiones empresariales -- 3. Indicar los aspectos constitutivos de una plataforma financiera para la gestión empresarial -- Para mitigar esta problemática, la implementación del sistema de información financiero propuesto contribuye al entorno competitivo de las pymes, lo cual permite automatizar procesos, estabilidad laboral y empresarial, reducción de costos, accesibilidad a nuevas tecnologías y crear las bases para la toma de decisiones, con la finalidad de mejorar la competitividad de las micro, pequeñas y medianas empresas

A number of important trends currently impact libraries. Academic libraries face the fundamental shift of collections toward ever increasing proportions of electronic content; public libraries continue to see vigorous interest in print materials, now supplemented by demand to provide e-books for lending. Breeding will explore these and other trends and describe some of the technologies available and emerging to help libraries meet the challenges involved in this context.
