BigData Analytics has emerged as a disruptive technology in many fields of businesses engineering and knowledge management. Among them, BigData eLearning Analytics play an important role in Virtual Campuses and eLearning platforms. Initially, BigData eLearning Analytics served as a basis for monitoring and decision making in traditional Learning Management Systems (LMS). However, BigData eLearning Analytics is playing a crucial role in the design of new LMS systems by enabling not only learning analytics but also the A3 paradigm (Anywhere, Anytime, Awareness), emotion-aware learning, trustworthy e-assessment and other trends to maximize learner’s motivation, experiences and outcome.
In this talk we will address and discuss current and new trends and challenges arising in BigData eLearning Analytics as a cornerstone for new generation of Learning Management Systems and Online Collaboration. The talk we will focus on massive data processing and mining techniques for BigData eLearning under efficiency and scalability requirements. We will analyse and discuss techniques related to software patterns for massive data processing, and identify various issues arising in mining large data sets. We will exemplify the discussion by real life examples, large learning data sets and case studies from a real Virtual Campus.

Despite the significant degree of technological maturity reached by modern telecommunications
infrastructures, new critical issues are emerging as side effects associated to their energy consump-
tion, environmental impact and related costs, now accounting for an important part of the networks'
operational expenditures. For this reason, the power consumption of telecommunication networks
has recently attracted the attention of both researchers and field experts in order to contain the
associated energy bills and reduce their ecological impact. Many of the proposed countermeasures,
introducing energy effciency in network equipment, focus exclusively on the reduction of the power
consumption, without adequately considering more traditional network engineering objectives such
as balancing resource utilization, routing policy, or resilience schemes. As a consequence, network
control plane strategies passed from one extreme to the other, from being totally energy-unaware
to exclusively energy-efficient at the expenses of load-balancing, with obvious impacts on the power
consumption in the former case and on the blocking rate in the latter one. Correctly handling
this problem implies introducing the concept of energy awareness within the overall routing and
trafic engineering framework, by also relying on the possibility of using alternate energy sources
and more the trafic according to the different billing policies. This also means solving a very com-
plex multi-objective optimisation approach aiming at containing the network's energy consumption
and ecological impact while balancing the overall load and maintaining an acceptable connection
demand satisfaction rate. The optimal solutions to such an optimisation problem, can be found
only in unaffordable times by using integer linear programming, so that other near-optimal solution
based on novel heuristic methods and engineering practices are needed.
Hence, the main goal of this keynote is presenting the current challenges and research trends
related to the introduction of energy-awareness in communication infrastructures by exploring the
emerging models necessary to formally characterize the energy consumption within networks and the
new energy-aware protocols, architectures, techniques and paradigms that, by considering power
usage as a new constraint, are capable to optimize the use of energy and reduce the ecological
footprint in order to achieve more sustainable large scale communication infrastructures that will
be a basis for growth and prosperity.
