Distributed spatio-temporal similarity search
(2006)In this paper we introduce the distributed spatio-temporal similarity search problem: given a query trajectory Q, we want to find the trajectories that follow a motion similar to Q, when each of the target trajectories is ...

The micropulse framework for adaptive waking windows in sensor networks
(2007)In this paper we present MicroPulse, a novel framework for adapting the waking window of a sensing device S based on the data workload incurred by a query Q. Assuming a typical tree-based aggregation scenario, the waking ...

Exploiting locality for scalable information retrieval in peer-to-peer networks
(2005)An important problem in unstructured peer-to-peer (P2P) networks is the efficient content-based retrieval of documents shared by other peers. However, existing searching mechanisms are not scaling well because they are ...

Article
Structuring topologically aware overlay networks using domain names
(2006)Overlay networks are application layer systems which facilitate users in performing distributed functions such as searches over the contents of other users. An important problem in such networks is that the connections ...

pFusion: A P2P architecture for internet-scale content-based search and retrieval
(2007)The emerging Peer-to-Peer (P2P) model has become a very powerful and attractive paradigm for developing Internet-scale systems for sharing resources, including files and documents. The distributed nature of these systems, ...

On constructing internet-scale P2P information retrieval systems
(2005)We initiate a study on the effect of the network topology on the performance of Peer-to-Peer (P2P) information retrieval systems. The emerging P2P model has become a very powerful and attractive paradigm for developing ...

SenseSwarm: A perimeter-based data acquisition framework for mobile sensor networks
(2007)This paper assumes a set of n mobile sensors that move in the Euclidean plane as a swarm. Our objectives are to explore a given geographic region by detecting and aggregating spatio-temporal events of interest and to store ...

Article
Synchrony measure for a neuron driven by excitatory and inhibitory inputs and its adaptation to experimentally-recorded data
(2017)The aim of the current work is twofold: firstly to adapt an existing method measuring the input synchrony of a neuron driven only by excitatory inputs in such a way so as to account for inhibitory inputs as well and secondly ...

Article
A Biophysical Model of Endocannabinoid-Mediated Short Term Depression in Hippocampal Inhibition
(2013)Memories are believed to be represented in the synaptic pathways of vastly interconnected networks of neurons. The plasticity of synapses, that is, their strengthening and weakening depending on neuronal activity, is ...

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 ...
