A mobile robot platform for open learning based on serious games and remote laboratories

Within the pedagogical community, Serious Games have arisen as a viable alternative to traditional course-based learning materials. Until now, they have been based strictly on software solutions. Meanwhile, research into Remote Laboratories has shown that they are a viable, low-cost solution for experimentation in an engineering context, providing uninterrupted access, low-maintenance requirements, and a heightened sense of reality when compared to simulations. This paper will propose a solution where both approaches are combined to deliver a Remote Laboratory-based Serious Game for use in engineering and school education. The platform for this system is the WebLab-Deusto Framework, already well-tested within the remote laboratory context, and based on open standards. The laboratory allows users to control a mobile robot in a labyrinth environment and take part in an interactive game where they must locate and correctly answer several questions, the subject of which can be adapted to educators' needs. It also integrates the Google Blockly graphical programming language, allowing students to learn basic programming and logic principles without needing to understand complex syntax.

VISIR deployment in undergraduate engineering practices

Practical sessions are the backbone of qualification in engineering education. It leads to a better understanding and allows mastering scientific concepts and theories. The lack of the availability of practical sessions at many universities and institutions owing to the cost and the unavailability of instructors the most of the time caused a significant decline in experimentation in engineering education over the last decades. Recently, with the progress of computer-based learning, remote laboratories have been proven to be the best alternative to the traditional ones, regarding to its low cost and ubiquity. Some universities have already started to deploy remote labs in their practical sessions. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well.

Addressing software impact in the design of remote laboratories

Remote Laboratories or WebLabs constitute a first-order didactic resource in engineering faculties. However, in many cases, they lack a proper software design, both in the client and server side, which degrades their quality and academic usefulness. This paper presents the main characteristics of a Remote Laboratory, analyzes the software technologies to implement the client and server sides in a WebLab, and correlates these technologies with the characteristics to facilitate the selection of a technology to implement a WebLab. The results obtained suggest the adoption of a Service Oriented Laboratory Architecture-based approach for the design of future Remote Laboratories so that client-agnostic Remote Laboratories and Remote Laboratory composition are enabled. The experience with the real Remote Laboratory, WebLab-Deusto, is also presented.

Evaluación de las artes y métodos de pesca empleados en el río Mazan

El informe detalla los trabajos desarrollados por el personal del área de Artes y métodos de pesca en aguas continentales de la Dirección de investigaciones y extracción, con la ayuda material proporcionada durante las labores de campo por el Comité de pescadores del río Mazán y el personal de la oficina regional de pesquería de Iquitos, específicamente por el encargado de la zona reservada del río Mazán.

Artes y métodos de pesca en las riveras del lago Titicaca

Expone el nivel técnico que han alcanzado los pescadores que habitan las riveras del lago Titicaca, así como sus artes y métodos de pesca más empleados por ellos. Los resultados presentados durante las labores de campo demuestran que la extracción pesquera del lago, se centra fundamentalmente en la captura del carachi, debido a que es la especie más abundante y de más fácil captura por su costumbre de vivir en lugares cercanos a la playa.

Características hidrográficas y sedimentológicas de la bahía de Sechura

En la zona central de la bahía de Sechura afloran principalmente Aguas Costeras Frías. En superficie y en condiciones normales la temperatura fluctúa de 15 a 24 °C, salinidad de 34,8 a 35,3 ups, oxígeno disuelto de 2 a 5,5 mL/L. La capa subsuperficial con valores menores a los de superficie, varían ante eventos El Niño y en menor escala en La Niña. Los sedimentos superficiales predominantes cerca a la costa son textura arenosa con bajo contenido orgánico que se extiende a mayor profundidad hacia el norte de Punta Aguja; textura areno limosa adyacentes a los de arena, ocupan gran extensión de la bahía, asociados con altos contenidos de materia orgánica, pequeñas extensiones de arena arcillosa y limo arenoso frente a la Bocana, Bayovar y Punta Tric Trac. Contenidos de carbonato más altos (70%) de origen biogénico frente a San Pablo, asociados a texturas de arena y arena limosa.
