This paper presents a Workflow Management System (WfMS) for procurement process automation in road pavement maintenance and management. It fits information infrastructure for monitoring and maintenance of pavements and roads. Through the two roles of administrator and major users (builder and subcontractors), the solution models the entire process. This way, risks of exceeding allocated budget, time consuming tasks, overcoming deadline, and time consuming quality control, as main issues in risk management, are reduced and controlled. © 2006-2017 by CCC.

In order to balance the preference of the artificial entities towards exploration or exploitation (in their transition rule), a novel technique is proposed for replacing the random function used by the classical Ant Colony Optimization (ACO) algorithms for solving the Traveling Salesman Problem (TSP). The proposed Beta Distribution function (B), or random. betavariate(a, b) has the proven capability (depicted through test-runs) of influencing the algorithm's solution quality and convergence speed. Consequently, this paper will introduce in the related work section the classical ACO algorithm, with a focus on the transition rule used for choosing the next node in the problem's associated graph, followed by the related work on this topic, and it will continue with the introduction of the B function which will be presented both from a theoretical and practical perspective in relation with the scope: balancing between exploration and exploitation in order to improve the performance of the ACO algorithm for the TSP. The paper concludes that the B-EAS has the ability to find better solution than EAS for a set of benchmarks from the TSPLib library. © 2006-2017 by CCC.

Risk management forecasts those situations that can damage the proposed goals or jeopardize the completion of projects in time. The aim of this paper is to highlight risk management tailored practices for pavement roads maintenance projects. All presented practices and risk management analysis are consistent with international standards, processes and assets. Present work also describes a particular analysis and prioritization of risk factors for their implementation in a web application. For risk mitigation we used the k-nearest neighbors (k-NN) algorithm, which is based on mathematical kernel density estimates nonparametric alternative method for reference class forecasting. This method helps project managers and planners to estimate durations in pavement management and maintenance systems and provides more realistic alternative dates and critical paths. © 2017, Gh.

Romanian scientist Florin Gheorghe Filip was born in 1947 and this year he turns 70. F.G. Filip is an engineer and Ph. D. in control engineering and computer science. Still very young, he became corresponding member of the Romanian Academy in 1991 (when he was only 44 years old), and, at 52 years old (1999), become full member in the highest learned society of Romania. From 1970 to 2000, he worked at the National R&D Institute in Informatics Bucharest (ICI). For 10 years, during 2000-2010, he was Vice President of the Romanian Academy. In 2010, he was elected President of the "Information Science and Technology" section of Romanian Academy. At present, he is the director of the Romanian Academy Library. His fields of scientific interest have been: decision support systems (DSS), large-scale systems control and optimization, technology management and foresight and IT application to cultural domain. He has authored/co-authored over 300 technical papers, 13 monographs, and edited/co-edited 24 contributed volumes. © 2006-2017 by CCC Publications.

Watching the evolution of the Semantic Web (SW) from its in-ception to these days we can easily observe that the main task the developers face while building it is to encode the human knowledge into ontologies and the human reasoning into dedicated reasoning engines. Now, the SW needs to have efficient mechanisms to access information by both humans and arti-ficial agents. The most important tools in this context are ontologies. The last years have been dedicated to solving the infrastructure problems related to ontologies: ontology management, ontology matching, ontology adoption, but as time goes by and these problems are better understood the research interests in this area will surely shift towards the way in which agents will use them to communicate between them and with humans. Despite the fact that interface agents could be bilingual, it would be more efficient, safe and swift that they should use the same language to communicate with humans and with their peers. Since anthropocentric systems entail nowadays multimodal interfaces, it seems suitable to build multimodal ontologies. Generic ontologies are needed when dealing with uncertainty. Multimodal ontologies should be designed taking into account our way of thinking (mind maps, visual thinking, feedback, logic, emotions, etc.) and also the processes in which they would be involved (multimodal fusion and integration, error reduction, natural language processing, multimodal fission, etc.). By doing this it would be easier for us (and also fun) to use ontologies, but in the same time the communication with agents (and also agent to agent talk) would be enhanced. This is just one of our conclusions related to why building generic multimodal ontologies is very important for future semantic web applications. © 2006-2010 by CCC Publications.

Membrane Computing is a branch of Computer Science initiated by Gheorghe Păun in 1998, in a technical report of Turku Centre for Computer Science published as a journal paper ("Computing with Membranes" in Journal of Computer and System Sciences) in 2000. Membrane systems, as Gheorghe Păun called the models he has introduced, are known nowadays as "P Systems" (with the letter P coming from the initial of the name of this research area "father"). This note is an overview of the impact in ISI WoS of Gheorghe Păun's works, focused on Membrane Computing and P Systems field, on the occasion of his 65th birthday anniversary. © 2006-2015 by CCC Publications.

With the development of mobile devices the security issue migrates from the PC platform to this new technology. Securing confidential information on the mobile platforms has been, is and will be a topical issue for the specialists. In this paper we propose a new solution in order to provide security of digital data that is transferred through today's available platforms for communication. We developed SmartSteg application that works on Android platform and it is able to hide and fast encrypt files using digital images of MB dimension as cover. LSB steganography is combined with a random function and symmetric key cryptography to transfer digital information, in a secure manner between smartphones that run under Android. © 2006-2013 by CCC Publications.

The aim of this survey article, dedicated to the 50th anniversary of Zadeh's pioneering paper "Fuzzy Sets" (1965), is to offer a unitary view to some important spaces in fuzzy mathematics: fuzzy real line, fuzzy topological spaces, fuzzy metric spaces, fuzzy topological vector spaces, fuzzy normed linear spaces. We believe that this paper will be a support for future research in this field. © 2006-2015 by CCC Publications.

This paper describes our experience in using e-learning platforms to support face to face instruction in academic field. We used Moodle as interactive e-learning tool to motivate students and involve them in resolving single and collaborative homework tasks. However, while many universities in the world use e-learning platforms, in our case this was for the first time used and it was a great teaching/learning experience. This paper aims to be easy to read and understand by proving the importance of using e-learning platforms in higher education. © 2014 Published by Elsevier B.V.

In the last years, several papers in literature have treated the multi-criteria decision making (MCDM) problems in neutrosophic environment. This approach had a starting point the fact that in many real life problems, decision makers have indeterminate, inconsistent or incomplete information about the alternatives with respect to criteria. A brief survey on the applications of neutrosophic sets in MCDM problems is proposed in this paper, hoping that, in this way, we will stimulate further studies and approaches. © 2016 IEEE.
