Adaptive noise canceling and edge detection in images using PVM on a NOW
(IEEE, 2000)A method for the processing of digital images using a two-dimensional LMS adaptive filter for noise reduction and subsequent edge detection is presented. This was implemented on a Parallel Virtual Machine (PVM) consisting ...

Argumentation based modeling of decision aiding for autonomous agents
(2004)Decision Aiding can be abstractly described as the process of assisting a user/client/decision maker by recommending possible courses of his action. This process has to be able to cope with incomplete and/or inconsistent ...

A case study of a virtual audience in a reconstruction of an ancient Roman odeon in Aphrodisias
(Association for Computing Machinery, Inc, 2005)The benefits of including virtual humans into cultural heritage reconstructions are twofold: the realism of architectural models is increased by populating them

Characterization of computational grid resources using low-level benchmarks
(2006)An important factor that needs to be taken into account by end-users and systems (schedulers, resource brokers, policy brokers) when mapping applications to the Grid is the performance capacity of hardware resources attached ...

Cognitive factors can influence self-motion perception (vection) in virtual reality
(ACM - Association for Computing Machinery, 2006)Research on self-motion perception and simulation has traditionally focused on the contribution of physical stimulus properties ('bottom-up factors') using abstract stimuli. Here, we demonstrate that cognitive ('top-down') ...

A distributed visualization system for crowd simulations
(2011)The visualization system of large-scale crowd simulations should scale up with both the number of visuals (views of the virtual world) and the number of agents displayed in each visual. Otherwise, we could have large scale ...

Employing virtual worlds for HCI education: A problem-based learning approach
(2012)In this paper we describe our experience focused on teaching an introductory course in HCI by employing a 3D virtual world. Our main pedagogical philosophy is presented which claims that problem-based learning activities ...
