Interoperability in eLearning Contexts. Interaction between LMS and PLE

Authors: Miguel Conde, Francisco García-Peñalvo, Jordi Piguillem, María Casany, and Marc Alier

Published in: OASIcs, Volume 21, 1st Symposium on Languages, Applications and Technologies (2012)

Abstract

The emergence of the Information and Communication Technologies and its application in several areas with varying success, implies the definition of a great number of software systems. Such systems are implemented in very different programming languages, using distinct types of resources, etc. Learning and Teaching is one of those application areas, where there are different learning platforms, repositories, tools, types of content, etc. These systems should interoperate among them to provide better and more useful learning services to students and teachers, and to do so web services and interoperability specifications are needed. This paper presents a service-based framework approach to facilitate the interoperability between Learning Management Systems and Personal Learning Environments, which has been implemented as a proof of concept and evaluated through several pilot experiences. From such experiences it is possible to see that interoperability among the personal and institutional environments it is possible and, in this way, learners can learn independently without accessing to the institutional site and teachers have information about learning that happens in informal activities.

01. A new concept of robustness

Authors: Ricardo García, Ángel Marín, Juan A. Mesa, Federico Perea, and Doroteo Verastegui

Published in: OASIcs, Volume 7, 7th Workshop on Algorithmic Approaches for Transportation Modeling, Optimization, and Systems (ATMOS'07) (2007)

Abstract

In this paper a new concept of robustness is introduced and the corresponding optimization problem is stated. This new concept is applied to transportation network designs in which the set of scenarios arising from the uncertainty of the parameters follows a probability distribution. The $p$-robustness concept is aimed to problems where the feasibility of the solutions is not affected by the uncertainty of the parameters. In order to compare the solution with those of other already known concepts of robustness, some computational experiments with real data are included.

Analysis of the Parameters of Transfers in Rapid Transit Network Design

Authors: Ricardo García, Armando Garzón-Astolfi, Angel Marín, Juan A. Mesa, and Francisco A. Ortega

Published in: OASIcs, Volume 2, 5th Workshop on Algorithmic Methods and Models for Optimization of Railways (ATMOS'05) (2006)

Abstract

The rapid transit network design problem consists of the location of train alignments and stations in an urban traffic context. The originality of our study is to incorporate into the location model the decisions about the transportation mode and the route, to be chosen for urban trips. This paper proposes a new design model which includes transfers between train lines. The objective of the model is to maximize the number of expected users in the transit network taking limited budgets into consideration, in addition to location and allocation constraints. Furthermore, the transfer costs are considered in the generalized public costs when the users change lines. Waiting time to take the metro and walking time to transfer is included in the formulation of the costs. The analysis of transfer parameters is carried out using a test network. Some computational experience is included in the paper.
