      Exploring database workloads on future clustered many-core architectures 

      Petrides, P.; Diavastos, Andreas; Trancoso, Pedro (2011)
      Decision Support System (DSS) workloads are known to be one of the most time-consuming database workloads that process large data sets. Traditionally, DSS queries have been accelerated using large-scale multiprocessor. In ...

      Getting ready for approximate computing: Trading parallelism for accuracy for dss workloads 

      Trancoso, Pedro (Association for Computing Machinery, 2014)
      Processors have evolved dramatically in the last years and current multicore systems deliver very high performance. We are observing a rapid increase in the number of cores per processor thus resulting in more dense and ...

      Minimum-hot-spot query trees for wireless sensor networks 

      Chatzimilioudis, Georgios; Zeinalipour-Yazdi, Constantinos D.; Gunopulos, Dimitrios (2010)
      We propose a distributed algorithm to construct a balanced communication tree that serves in gathering data from the network nodes to a sink. Our algorithm constructs a near-optimally balanced communication tree with minimum ...

      Power efficiency through tuple ranking in wireless sensor network monitoring 

      Andreou, Panayiotis G.; Zeinalipour-Yazdi, Constantinos D.; Chrysanthis, Panos K.; Samaras, George S. (2011)
      In this paper, we present an innovative framework for efficiently monitoring Wireless Sensor Networks (WSNs). Our framework, coined KSpot, utilizes a novel top-k query processing algorithm we developed, in conjunction with ...
