PURPOSE To evaluate the potential of brilliant blue G (BBG) and indocyanine green (ICG) for intraoperative staining of the internal limiting membrane (ILM) with respect to perceivable contrast. METHODS In a retrospective clinical case series the authors analyzed 26 consecutive chromovitrectomy interventions in 26 patients with macular holes, epiretinal(More)
Coordinating efforts of teams of professionals to search and rescue victims of emergency situations is a key point in disaster management. The disasters scenarios have been modelled as a distributed and large scale Extended Generalized Allocation Problem (E-GAP). We propose a novel algorithm to approximate the solution of E-GAP based on the theoretical(More)
In multiagent systems, Distributed Constraint Optimization Problem (DCOP) has been used as a formalism to model a wide range of agents' coordination issues. An approach based on cooperative mediation was recently proposed as a new way to find the optimal solution to DCOP. An important question about any solution to DCOP is whether it is fast enough to be(More)
—Urban mobility problems affects the vast majority of cities nowadays. Thus, systems that provide real time information to assist in planning routes and choosing the most appropriate paths are essential to make transport more effective. As an alternative solution to problems related to mobility in cities, there are the so-called Intelligent Transportation(More)
Solar energy has been subject of great development in the past years, which led to the concept of Solar Roads: photovoltaic panels along the highways and roads. SmartSolarGrid is the merge of Solar Roads with Smart Grids, a new electrical distribution grid with improved efficiency and control. The goal of this work is to develop a software tool that further(More)
This paper addresses distributed task scheduling problems as a distributed version of the Resource-Constrained Project Scheduling Problem (RCPSP). We propose and evaluate a novel approach for the distributed RCPSP based on theoretical models of division of labor in social insect colonies. Our approach uses a probabilistic decision-making model based on the(More)
