Activity delay patterns in project networks
Alexei Vazquez, Chrysostomos Marasinou, Georgios Kalogridis +1
Delays in activities completion drive human projects to schedule and cost overruns. It is believed activity delays are the consequence of multiple idiosyncrasies without specific p…
Activity networks determine project performance
Alexei Vazquez, Iacopo Pozzana, Georgios Kalogridis +1
Projects are characterised by activity networks with a critical path, a sequence of activities from start to end, that must be finished on time to complete the project on time. Wat…
Spreading of performance fluctuations on real-world project networks
Iacopo Pozzana, Christos Ellinas, Georgios Kalogridis +1
Understanding the role of individual nodes is a key challenge in the study of spreading processes on networks. In this work we propose a novel metric, the reachability-heterogeneit…
Connectivity of Cooperative Ad hoc Networks
Orestis Georgiou, Georgios Kalogridis, Hachem Yassine +1
The connectivity properties of ad hoc networks have been extensively studied over the past few years, from local observables, to global network properties. In this paper we introdu…
Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities
Zhong Fan, Parag Kulkarni, Sedat Gormus +6
Optimization of energy consumption in future intelligent energy networks (or Smart Grids) will be based on grid-integrated near-real-time communications between various grid elemen…
