Agent-based modelling of the evacuation of endangered areas in crisis situations
Springer Science and Business Media LLC - Tập 2 - Trang 35-45 - 2014
František Čapkovič
The evacuation process from endangered areas (EA) into safe spaces in crisis situations is modelled by means of simple agents (gate-ways equipped by sensors). Petri nets (PN) are utilized here to model the EA structure as well as the agents and their cooperation. More precisely, timed PN (TPN) and first-order hybrid PN (FOHPN) are used to do this. Rooms, other spaces to be evacuated (corridors) an... hiện toàn bộ
Towards an enhanced user’s preferences integration into ranking process using dominance approach
Springer Science and Business Media LLC - Tập 5 - Trang 15-25 - 2017
Mohammed Mouhir, Youssef Balouki, Taoufiq Gadi
User preference is very important in orienting data miner, and this is the reason why these user preferences are integrated in the mining process, where they are coupled with Association Rules Mining “ARM” Algorithms to select only Association Rules “ARs” that satisfy the user’s wishes and expectations. Within this framework, several approaches were proposed to overcome some problems which persist... hiện toàn bộ
IMSR_PreTree: an improved algorithm for mining sequential rules based on the prefix-tree
Springer Science and Business Media LLC - Tập 1 - Trang 97-105 - 2014
Thien-Trang Van, Bay Vo, Bac Le
Sequential rules generated from sequential patterns express temporal relationships among patterns. Sequential rule mining is an important research problem because it has broad application such as the analyses of customer purchases, web log, DNA sequences, and so on. However, developing an efficient algorithm for mining sequential rules is a difficult problem due to the large size of the sequential... hiện toàn bộ
Evaluation of SPARQL-compliant semantic search user interfaces
Springer Science and Business Media LLC - Tập 2 - Trang 191-199 - 2015
Adam Styperek, Michal Ciesielczyk, Andrzej Szwabe, Pawel Misiorek
A regular user of a semantic search system frequently posses no knowledge about the SPARQL language nor about the ontology of a given knowledge base, especially when it provides domain-unspecific data obtained from heterogeneous sources. Nevertheless, he/she should be provided with tools enabling both intuitive and effective exploration of RDF-compliant knowledge bases. Natural language querying i... hiện toàn bộ
A new multilevel reversible bit-planes data hiding technique based on histogram shifting of efficient compressed domain
Springer Science and Business Media LLC - Tập 5 - Trang 185-196 - 2018
Rashid Abbasi, Bin Luo, Gohar Rehman, Haseeb Hassan, Muhammad Shahid Iqbal, Lixiang Xu
In this paper, we proposed a new technique for reversible data hiding based on efficient compressed domain with multiple bit planes. We conducted a sequence of experiments to use block division scheme to appraise the result with different parameters and amended the probability of zero point in every block of histogram. This scheme attained more embedding capacity and high-quality of stego-image. E... hiện toàn bộ
Revisiting urban air quality forecasting: a regression approach
Springer Science and Business Media LLC - Tập 5 - Trang 177-184 - 2018
Kostas Karatzas, Nikos Katsifarakis, Cezary Orlowski, Arkadiusz Sarzyński
We address air quality (AQ) forecasting as a regression problem employing computational intelligence (CI) methods for the Gdańsk Metropolitan Area (GMA) in Poland and the Thessaloniki Metropolitan Area (TMA) in Greece. Linear Regression as well as Artificial Neural Network models are developed, accompanied by Random Forest models, for five locations per study area and for a dataset of limited feat... hiện toàn bộ

Control of autonomous robot behavior using data filtering through adaptive resonance theory
Springer Science and Business Media LLC - Tập 5 - Trang 85-94 - 2017
Adam Barton, Eva Volna, Martin Kotyrba
The aim of the article is to use neural networks to control autonomous robot behavior. The type of the controlling neural network was chosen a backpropagation neural network with a sigmoidal transfer function. The focus in this article is put on the use adaptive resonance theory (ART1) for data filtering. ART1 is used for preprocessing of the training set. This allows finding typical patterns in t... hiện toàn bộ

Discovering crisis models to help assess coordination plans
Springer Science and Business Media LLC - Tập 4 - Trang 97-110 - 2016
Nguyen-Tuan-Thanh Le, Chihab Hanachi, Serge Stinckwich, Tuong-Vinh Ho
Recently, we have witnessed an increasing number of crises, not only natural disasters but also man-made ones. Coordination among several stakeholders is the key factor to reduce the damage caused by a crisis. However, the plan for coordination can be expressed under various representations, including textual format—the most used one in reality but hard to analyze its efficiency. We consider in th... hiện toàn bộ
