• A perfect hashing incremental scheme for unranked trees using pseudo-minimal automata

  Publikacja

  • R. Carrasco
  • J. Daciuk

  - RAIRO-THEORETICAL INFORMATICS AND APPLICATIONS - Rok 2009

  We describe a technique that maps unranked trees to arbitrary hash codes using a bottom-up deterministic tree automaton (DTA). In contrast to other hashing techniques based on automata, our procedure builds a pseudo-minimal DTA for this purpose. A pseudo-minimal automaton may be larger than the minimal one accepting the same language but, in turn, it contains proper elements (states or transitions that are unique) for every input...

• LLA : A New Anypath Routing Scheme Providing Long Path Lifetime in VANETs

  Publikacja

  • J. Rak

  - IEEE COMMUNICATIONS LETTERS - Rok 2014

  Vehicular ad-hoc networks (VANETs) are a promising solution to improve the road traffic safety, reduce the environmental pollution, or simply provide the on-board infotainment services. However, these actions are often not possible due to high mobility of vehicles causing frequent failures of VANET links. In this paper, we focus on anypath routing to improve the reliability of multihop VANET communications. In particular, the paper...

• Evolutionary sets of safe ship trajectories with speed reduction manoeuvres within traffic separation schemes

  Publikacja

  • R. Szłapczyński

  - Polish Maritime Research - Rok 2014

  In the previous paper the author presented the evolutionary ship trajectory planning method designed to support Traffic Separation Schemes (TSS). This time the extensions of this method are described which allow to combine evolutionary trajectory planning with speed reduction manoeuvres. On TSS regions with higher than usual density of traffic and smaller distances between ships, the course alterations alone are not always sufficient...

  Publikacja

  • J. Konorski

  - Rok 2018

  In wireless networks, stations can improve their received quality of service (QoS) by handling packets of source flows with higher priority. Additionally, in cooperative relay networks, the relays can handle transit flows with lower priority. We use game theory to model a two-hop relay network where each of the two involved stations can commit such selfish QoS manipulation. We design and evaluate a reputation-based incentive scheme...

  The integration of electric vehicles (EVs) is rapidly growing compared to conventional vehicles in Qatar. To assess how these electric vehicles will impact Qatar’s distribution network, it is necessary to accurately model EV loads. However, EV loads exhibit uncertainties due to driving behaviour in charging time, state of charge (SOC), number of trips, and distance travelled. This necessitates the development of a probabilistic...
