Dopamine (DA) modulates basal ganglia (BG) activity for initiation and execution of goal‐directed movements and habits. While most studies are aimed to striatal function, the cellular and molecular mechanisms underlying dopaminergic regulation in other nuclei of the BG are not well understood. Therefore, we set to analyze the dopaminergic modulation occurring in subthalamo‐nigral synapse, in both...
Potassium channels play an important role in modulating synaptic activity both at presynaptic and postsynaptic levels. We have shown before that presynaptically located KV and KIR channels modulate the strength of corticostriatal synapses in rat brain, but the role of other types of potassium channels at these synapses remains largely unknown. Here, we show that calcium‐dependent potassium channels...
High-performance interconnection networks such as InfiniBand, ASI, Autonet, and Myrinet have the property of link level flow control. As such, alterating the routing function while the network is operational is a complex process, because the danger of packet deadlocks must be addressed. Over the past 5–6 years this problem has been addressed and solved by the research community. This chapter...
This work presents the integration of remote laboratories, viewed as a set of services, into Learning Management Systems (LMSs). Remote laboratories are nowadays essential at distance learning, since students are not able to use face-to-face traditional laboratories. These remote laboratories can be employed by faculty within virtual classrooms, so that students can carry out their on-line experiments...
MUREE project aims at the development of courses for training specialists about renewable energy production by combining face-to-face learning with on-line attendance. In this sense, remote laboratories are nowadays essential for distance education, even more within MUREE project, since Jordan students are not able to use face-to-face traditional laboratories due to their different physical location...
The creation and publication of utilities as services (the most widely known being Infrastructure as a Service, IaaS, Platform as a Service, PaaS, and Software as a Service, SaaS) has been a hot topic of research and development for the recent years. They allow easy creation and deployment of infrastructures and applications which increase the versatility and usefulness of the Information Technology...
The lack of tracking and storing capabilities for the results of web-based learning activities is an issue that remains unsolved. Transitions or interactions defined by teachers through a set of conditions still require programming skills that stay far beyond the desired final results. In addition to this, authoring tools should be powerful enough to let lecturers generate contents which are high-quality,...
The acquisition of practical competences is an essential point of any engineering curricula, being more challenging than the acquisition of theoretical competences. For this, the use of laboratories is totally essential, and, in the case of distance education, this becomes even more challenging since students are located physically distant from the laboratories that they should use to obtain such...
Learning Management Systems (LMSs) are Information Technology (IT) platforms whose aim is the support of learning processes. Among the features a LMS provides we can find communication tools such as forums, evaluation tools such as questionnaires, or grade tools. A number of LMSs exist, both open-source (such as .LRN, Sakai, or Moodle) and proprietary solutions (such as Blackboard). Among the wide...
Merging a Learning Management System (LMS) and a social network has social advantages for students. Among others, students can show off their achievements among their acquaintances, which in turn improves their social leadership and self-esteem. This is specially true in the case of distance learning, where there are no physical interactions between students, so their student life is totally isolated...
This paper presents a new framework to automatically evaluate the students' learning in the context of a subject focused on the configuration of network services. Unlike traditional platforms based on theoretical content, our automatic system will be able to immediately assess students' practical skills and, as a consequence, provide them with feedback about the correctness of their activities. Furthermore,...
In this paper, we present our work on enhancing the technological infrastructure at Spanish National University for Distance Education (UNED, Universidad Nacional de Educación a Distancia) with cloud computing principles. This includes the development of (1) virtualized environments to allow students to do practical exercises easily in the field of networks and communications; and (2) load forecasting...
Overlapping Reconfiguration is currently the most efficient method to reconfigure an interconnection network, but is only valid for systems that apply distributed routing. This paper proposes a solution which enables utilization of Overlapping Reconfiguration in a source routed environment. We demonstrate how a synchronized injection of tokens has a significant impact on the performance of the method...
Recent years, computer performance has been significantly increased. As a consequence, data I/O systems have become bottlenecks within systems. In order to alleviate this problem, Advanced Switching Interconnect was proposed as a new standard for future high-performance interconnects. The Advanced Switching specification establishes a fabric management infrastructure, which is in charge of maintaining...
Advanced switching is a new high-speed industrial standard serial interconnect. It is defined as a switching fabric architecture based on the PCI express technology. The advanced switching specification establishes a management infrastructure which maintains the fabric operation. The topology discovery process is triggered after fabric initialization and every time a topological change is detected...
