OER Development and Promotion. Outcomes of an International Research Project on the OpenCourseWare Model

In this paper, we describe the successful results of an international research project focused on the use of Web technology in the educational context. The article explains how this international project, funded by public organizations and developed over the last two academic years, focuses on the area of open educational resources (OER) and particularly the educational content of the OpenCourseWare (OCW) model. This initiative has been developed by a research group composed of researchers from three countries. The project was enabled by the Universidad Politécnica de Madrid OCW Office�s leadership of the Consortium of Latin American Universities and the distance education know-how of the Universidad Técnica Particular de Loja (UTPL, Ecuador). We give a full account of the project, methodology, main outcomes and validation. The project results have further consolidated the group, and increased the maturity of group members and networking with other groups in the area. The group is now participating in other research projects that continue the lines developed her

Modeling a New AQM Model for Internet Chaotic Behavior Using Petri Nets

Formal modeling is considered one of the fundamental phases in the design of network algorithms, including Active Queue Management (AQM) schemes. This article focuses on modeling with Petri nets (PNs) a new scheme of AQM. This innovative AQM is based on a discrete dynamical model of random early detection (RED) for controlling bifurcations and chaos in Internet congestion control. It incorporates new parameters (α,β) that make possible better stability control over oscillations of an average queue length (AQL) at the router. The PN is validated through the matrix equation approach, reachability tree, and invariant analysis. The correctness is validated through the key properties of reachability, boundedness, reversibility, deadlock, and liveness

Bifurcation analysis for the Internet congestions

The bifurcation and chaotic behavior of TCP may cause heavy oscillation of average queue length at routers and induce network instability. In this context, congestion control in the Internet is a challenging problem of key importance. This work presents a new discrete dynamical model of Random Early Detection (RED) using beta distribution for controlling bifurcations and chaos in the internet congestion control. The numerical analysis and the simulation experiments show that this new Active Queue Management (AQM) model can obtain the stable average queue length to the desired fix point. The model programmed with Python and Mathematica incorporates new parameters (α, β) that make it possible to stabilize oscillations of averaged router queue length and to be close to stationary state

The MOOC Offer in Open Education: A Revision of the First IEEE Education Society' MOOC

The IEEE Education Society aims to satisfy the academic career needs of its membership offering new opportunities with the development of web-based educational resources. Its current Strategic Plan contains a goal consisting on aiming 'to be a relevant source for information and resources for the engineering educator and support the educational needs of faculty members and academic departments' through the 'promotion of Open Educational Resources (OER)'. Aligned with this direction several actions have been started. One of them was the publication of an IEEE MOOC in IEEEx, entitled 'Foundations of Open Education and OER repositories' and delivered free in two editions along 2017. This paper aims to establish guidelines to follow in the process of reviewing and updating the IEEE MOOC performing an exploratory study with other searched and selected MOOCs on the topics of Open Education and Open Educational Resources (OER). The main findings of the MOOC corpus analysis have allowed identifying different actions aimed at improving and revising the course as well as better dissemination to its membership
