Enhancing smart environments with mobile robots

Sensor networks are becoming popular nowadays in the development of smart environments. Heavily relying on static sensor and actuators, though, such environments usually lacks of versatility regarding the provided services and interaction capabilities. Here we present a framework for smart environments where a service robot is included within the sensor network acting as a mobile sensor and/or actuator. Our framework integrates on-the-shelf technologies to ensure its adaptability to a variety of sensor technologies and robotic software. Two pilot cases are presented as evaluation of our proposal.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Revisiting the Maxillary Teeth in 384 Subjects Reveals A Deviation From the Classical Aesthetic Dimensions

Dental esthetics need to be defined from the scientific perspective in order to obtain predictable treatment outcomes and avoid the effects of subjectivisms on the part of the dental profesional. It can be deduced that the ideal dimensions in the maxillary anterior sector are difficult to establish. Therefore, the primary purpose of this study was to define the dimensions of the maxillary anterior teeth and the relationships between them. In addition, an analysis was made to reinvestigate whether they complied with the Golden proportion, the RED (Recurrent Esthetic Dental) proportion and the Golden percentage. A total of 2304 tooth corresponding to 384 subjects were evaluated. The central incisor presented a mean width of 8.58 mm and a height of 9.35 mm, while the lateral incisor presented a width of 6.69 mm and a height of 7.75 mm. The mean width of the canine was 7.69 mm, with a height of 8.68 mm. The teeth revisited in this study did not comply with the ideal dimensions in the anterior maxillary sector as established by the Golden proportion, Golden percentage and RED. The information obtained from this study can be clinically applied to restore the dimensions during periodontal surgery, restorative dentistry and prosthetic rehabilitation

Improvement of the sensory and autonomous capability of robots through olfaction: the IRO Project

Proyecto de Excelencia Junta de Andalucía TEP2012-530Olfaction is a valuable source of information about the environment that has not been su ciently exploited in mobile robotics yet. Certainly, odor information can contribute to other sensing modalities, e.g. vision, to successfully accomplish high-level robot activities, such as task planning or execution in human environments. This paper describes the developments carried out in the scope of the IRO project, which aims at making progress in this direction by investigating mechanisms that exploit odor information (usually coming in the form of the type of volatile and its concentration) in problems like object recognition and scene-activity understanding. A distinctive aspect of this research is the special attention paid to the role of semantics within the robot perception and decisionmaking processes. The results of the IRO project have improved the robot capabilities in terms of efciency, autonomy and usefulness.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Treatment alternatives for the rehabilitation of the posterior edentulous maxilla

Rehabilitation of the edentulous maxilla with implant-supported fixed dental prostheses can represent a significant clinical challenge due to limited bone availability and surgical access, among other factors. This review addresses several treatment options to replace missing teeth in posterior maxillary segments, namely the placement of standard implants in conjunction with maxillary sinus floor augmentation, short implants, tilted implants, and distal cantilever extensions. Pertinent technical information and a concise summary of relevant evidence on the reported outcomes of these different therapeutic approaches are presented, along with a set of clinical guidelines to facilitate decision-making processes and optimize the outcomes of therapy

Optimización de la red de distribución de una compañía de lácteos en Colombia

En el caso de la compañía que nos permite elaborar este trabajo podemos evidenciar que desde su fundación en 1945, y durante sus 66 años de labores ha sido una de las empresas líderes en buscar la calidad y el mejoramiento continuo en todas sus actividades a todo nivel de la organización, y como respuesta a esta continua búsqueda hoy cuenta con una gran variedad de productos, elaborados con los más altos estándares de calidad y que se han posicionado en el mercado en forma contundente, ubicándola como empresa pionera en este modelo de negocio. Una política de esta organización es estar a la vanguardia en estrategias que generen valor agregado a todos los procesos y operaciones, y desde ese punto de vista han considerado a la logística como la herramienta integradora de todos los elementos fundamentales dentro de una organización, sabiendo que mediante la aplicación ordenada y lógica de esta, se logra la sostenibilidad y la consecución de altísimos índices de productividad. Este marco ha generado que cada vez las compañías no solo compitan con sus productos estrellas sino que se vean obligados a mejorar significativamente sus cadenas de abastecimiento, para lograr la disminución de costos operativos y lograr agilidad en la colocación de sus productos en manos del cliente fina

Discrete Equivalence of Non-positive at Infinity Plane Valuations

Non-positive at infinity valuations are a class of real plane valuations which have a nice geometrical behavior. They are divided in three types. We study the dual graphs of non-positive at infinity valuations and give an algorithm for obtaining them. Moreover we compare these graphs attending the type of their corresponding valuation

Alonso Vázquez, el pintor desde la perspectiva de su obra polícroma

La escultura polícroma es una tipología de obra artística. Debe considerarse como un conjunto, cuyos dos elementos constituyentes, la talla y la pintura, son técnicas que no se pueden disociar, pues se perdería la esencia original de la obra. En la escuela sevillana, tan profusa en artistas, no todos consiguieron la relevancia que desearon en la pintura. Pero no hay que desfavorecer, en las críticas, a los artistas que participaron de manera activa, con profesionalidad y calidad técnica, en los procesos polícromos. Alonso Vázquez, fue una de las figuras más destacada de la pintura de finales del siglo XVI, cuya aportación a la técnica de la policromía merece ser tenida en consideración.Artículo revisado por pare
