      The KGP model of agency 

      Kakas, Antonis C.; Mancarella, P.; Sadri, F.; Stathis, Kostas; Toni, F. (2004)
      This paper presents a new model of agency, called the KGP (Knowledge, Goals and Plan) model. This draws from the classic BDI model and proposes a hierarchical agent architecture with a highly modular structure that synthesises ...

      Knowledge qualification through argumentation 

      Michael, Loizos; Kakas, Antonis C. (2009)
      We propose a framework that brings together two major forms of default reasoning in Artificial Intelligence: default property classification in static domains, and default property persistence in temporal domains. Emphasis ...

      Language usage analysis for EMF metamodels on GitHub 

      Babur, Önder; Constantinou, Eleni; Serebrenik, Alexander (Springer, 2023-12)
      Context: EMF metamodels lie at the heart of model-based approaches for a variety of tasks, notably for defining the abstract syntax of modeling languages. The language design of EMF metamodels itself is part of a design ...

      A Large-scale Analysis of Content Modification by Open HTTP Proxies 

      Tsirantonakis, Giorgos; Ilia, Panagiotis; Ioannidis, Sotiris; Athanasopoulos, Elias; Polychronakis, Michalis (2018)
      Open HTTP proxies offer a quick and convenient solution for routing web traffic towards a destination. In contrast to more elaborate relaying systems, such as anonymity networks or VPN services, users can freely connect ...

      A latency-based object placement approach in content distribution networks 

      Pallis, George C.; Vakali, Athena I.; Stamos, Kostas; Sidiropoulos, Antonis; Katsaros, Dimitrios S.; Manolopoulos, Yannis (2005)
      Content Distribution Networks (CDNs) are increasingly being used to disseminate data in today's Internet. The growing interest in CDNs is motivated by a common problem across disciplines: how does one reduce the load on ...

      Layered strategies and protocols for argumentation-based agent interaction 

      Kakas, Antonis C.; Maudet, N.; Moraïtis, Pavlos (2005)
      Communication between agents needs to be flexible enough to encompass together a variety of different aspects such as, conformance to society protocols, private tactics of the individual agents, strategies that reflect ...

      LDPC decoding on the Intel SCC 

      Diavastos, Andreas; Petrides, P.; Falcão, G.; Trancoso, Pedro (2012)
      Low-Density Parity-Check (LDPC) codes are powerful error correcting codes used today in communication standards such as DVB-S2 and WiMAX to transmit data inside noisy channels with high error probability. LDPC decoding is ...

      Learning from the current status of agile adoption 

      Kapitsaki, Georgia M.; Christou, Marios Andreas (2015)
      Software processes have evolved significantly since the first formal appearance of software engineering. The academia and the industry have introduced, embraced or rejected various methodologies that are more or less ...

      Learning multiple predicates 

      Kakas, Antonis C.; Lamma, E.; Riguzzi, F. (1998)
      We present an approach for solving some of the problems of top-down Inductive Logic Programming systems when learning multiple predicates. The approach is based on an algorithm for learning abductive logic programs. Abduction ...

      Learning non-monotonic logic programs: Learning exceptions 

      Dimopoulos, Yannis; Kakas, Antonis C. (1995)
      In this paper we present a framework for learning non-monotonic logic programs. The method is parametric on a classical learning algorithm whose generated rules are to be understood as default rules. This means that these ...

      Learning optimisation by high firing irregularity 

      Cleanthous, A.; Christodoulou, Chris C. (2012)
      In a network of leaky integrate-and-fire (LIF) neurons, we investigate the functional role of irregular spiking at high rates. Irregular spiking is produced by either employing the partial somatic reset mechanism on every ...
