We study a heterogeneous two-tier wireless sensor network in which N access points (APs) collect sensing data from densely distributed sensors and then forward the to M fusion centers (FCs). This node deployment problem is modeled as an optimization with total power consumption of its cost function. The necessary conditions optimal AP FC are explored this paper. provide variation Voronoi Diagra...

Background: Evidence of patient and public involvement (PPI) in health research dissemination is weak and the development of mechanisms to assist the adoption and diffusion of PPI outcomes into research findings, patient experience and clinical practice is at an early stage. Aim: This paper seeks directly to address this weakness by increasing researchers’ awareness and understanding of the pot...

MyUniversity is a European project to foster the eParticipation in European higher education institutions and allow their members to influence the final decision making performed by the institutions’ authorities. A framework, composed of the two existing interactive tools Gov2Demoss and Pnyx.eVoting, and a methodology to manage eParticipation initiatives have been created for this purpose. This...

This study reports the impact of high sensitivity to early exchange in 11-grade, CSCL triads solving welland ill-structured problems in Newtonian Kinematics. Analysis of the evolution of participation inequity (PI) in group discussions suggested that participation levels tended to get locked-in relatively early on in the discussion. Similarly, high (low) quality member contributions made earlie...
