In this paper we discuss our preliminary experiences in designing a visual system for social data analysis in collaboration between citizens and municipal authorities through a web-based open government system. Based on the integration of theoretical models with findings from formative evaluations and stakeholder workshops with a prototype system, we present a multiperspective visualization mod...

This paper addresses synchronizing two coupled chaotic FitzHugh–Nagumo (FHN) neurons with weakly gap junction under external electrical stimulation (EES). To transmit information among coupled neurons, by generalization of the integer-order FHN equations of the coupled system into the fractional-order in frequency domain using Crone approach, the behavior of each coupled neuron relies on its pa...

Vergil’s Aeneid, written in the Augustan period, when Rome appeared at height of its urban development and was widely regarded as city par excellence, powerfully addresses changes that space experienced over time. In poem, different sites appear modified by many agents who had appropriated, transformed, crafted them through a range religious civic practices. Subtly, Vergil takes topic brings Ro...

Power system stabilizers have been widely used and successfully implemented for the improvement of power system damping. However, a fixed parameter power system stabilizer tends to be sensitive to variations in generator dynamics so that, for operating conditions away from those used for design, the effectiveness of the stabilizer can be greatly impaired. With the advent of microprocessor techn...

In recent years, DC microgrid has attracted considerable attention of the research community because of the wide usage of DC power-based appliances. However, the acceptance of DC microgrid by power utilities is still limited due to the issues associated with the development of a reliable protection scheme. The high magnitude of DC fault current, its rapid rate of rising and absence of zero cros...
