  1. Fuzzy Logic for Intelligent Control System Using Soft Computing Applications, SENSORS by MDPI, 2021, Catalin Dumitrescu, Petrica Ciotirnae, Constantin Vizitiu,

    Abstract: When considering the concept of distributed intelligent control, three types of components can be defined: (i) fuzzy sensors which provide a representation of measurements as fuzzy subsets, (ii) fuzzy actuators which can operate in the real world based on the fuzzy subsets they receive, and (iii) the fuzzy components of the inference. As a result, these elements generate new fuzzy subsets from the fuzzy elements that were previously used. The purpose of this article is to define the elements of an interoperable technology Fuzzy Applied Cell Control-soft computing language for the development of fuzzy components with distributed intelligence implemented on the DSP target. The cells in the network are configured using the operations of symbolic fusion, symbolic inference and fuzzy– real symbolic transformation, which are based on the concepts of fuzzy meaning and fuzzy description. The two applications presented in the article, Agent-based modeling and fuzzy logic for simulating pedestrian crowds in panic decision-making situations and Fuzzy controller for mobile robot, are both timely. The increasing occurrence of panic moments during mass events prompted the investigation of the impact of panic on crowd dynamics and the simulation of pedestrian flows in panic situations. Based on the research presented in the article, we propose a Fuzzy controller-based system for determining pedestrian flows and calculating the shortest evacuation distance in panic situations. Fuzzy logic, one of the representation techniques in artificial intelligence, is a well-known method in soft computing that allows the treatment of strong constraints caused by the inaccuracy of the data obtained from the robot’s sensors. Based on this motivation, the second application proposed in the article creates an intelligent control technique based on Fuzzy Logic Control (FLC), a feature of intelligent control systems that can be used as an alternative to traditional control techniques for mobile robots. This method allows you to simulate the experience of a human expert. The benefits of using a network of fuzzy components are not limited to those provided distributed systems. Fuzzy cells are simple to configure while also providing high-level functions such as mergers and decision-making processes.

  3. Crowdsensing Influences and Error Sources in Urban Outdoor Wi-Fi Fingerprinting Positioning, Sensors - MDPI, 2020, Cristian-Liviu Leca, Ioan Nicolaescu, Petrica Ciotirnae

    Abstract: Wi-Fi fingerprinting positioning systems have been deployed for a long time in location-based services for indoor environments. Combining mobile crowdsensing and Wi-Fi fingerprinting systems could reduce the high cost of collecting the necessary data, enabling the deployment of the resulting system for outdoor positioning in areas with dense Wi-Fi coverage. In this paper, we present the results attained in the design and evaluation of an urban fingerprinting positioning system based on crowdsensed Wi-Fi measurements. We first assess the quality of the collected measurements, highlighting the influence of received signal strength on data collection. We then evaluate the proposed system by comparing the influence of the crowdsensed fingerprints on the overall positioning accuracy for different scenarios. This evaluation helps gain valuable insight into the design and deployment of urban Wi-Fi positioning systems while also allowing the proposed system to match GPS-like accuracy in similar conditions.

  4. Design and Implementation of a Collaborative Communication Network for Video Conference Services, Journal of Military Technology, 2020, Mihaita Radoi, Petrica Ciotirnae,

    Abstract: Under the current global conditions, strong emphasis is put on saving resources and reducing costs, migrating to collaborative unified communications solutions and developing open-source Web applications. The secure video-conferencing system will mainly use VoIP and WebRTC technologies to make multimedia calls, allowing end-users mobile and remote access (MRA) and therefore to facilitate communication between different networks, as well as the accessibility and the interoperability with any type of technology and device. This article will analyze the scalable implementation of the real-time communications network, providing redundancy and load balancing, therefore ensuring the high availability of the entire collaborative communications system. The call control and the dial plan are done through the Unified Call Manager software and WebRTC videoconferencing external access functionality is provided by configuring Traversal Using Relays around NAT (TURN) service across the Expressway Series server pair (Core & Edge). The ability to manage and monitor virtual meetings remains the responsibility of the open-source management tools.

  5. QoS Prioritization Behavior in an Broadband Hybrid Network, Journal of Military Technology, 2019, Vasile-Dorinel NICOLAE and Petrică CIOTÎRNAE,

    Abstract: A broadband network must have the ability to transport a large amount of information in an efficient way, regardless of the type of service (voice, data, and video). A very good solution for safe and lossless transmission of data from IP access networks was the use of ATM at the core level, packing IP into ATM cells. Nowadays, most ISPs use IP over MPLS, because it allows, through the use of traffic engineering, interconnection with other sections using different switching technologies, and easy application of QoS policies and prioritization.

  6. Integrated Management of Transport and Commutation Resources over the Network Layer, Journal of Military Technology, 2019, Marius-Ioan CANDREA-BOZGA and Petrică CIOTÎRNAE

    Abstract: In the information and automation era, the activities of today’s society are based on communications media with fast and secure transmission of information. Because of the information dependency, today’s networking solutions must transport more data traffic and deliver it in a fast and efficient way. It is useless to assign an appropriate epithet to the degree of importance that efficient and accurate design and the use of a management mechanism appropriate to the necessity, have in the context of the current society. The usage of programming via Python for increasing management capabilities is required in order to do high performance management of a network. One of the most important aspects of managing a large scale network that uses various platforms bought from different vendors is how to manage all these systems using a unique management platform. The current paper is concerned with Python capabilities put to good use, to develop an Integrated Management platform that performs the management of the devices that form or are part of the telecommunications network. The topologies and the script programming were done in GNS3 using Ubuntu Docker Containers with Python installed, to remotely configure CISCO IOS MultyLayer Switches and Routers.

  8. Experimental and Numerical Studies of the Progressive Collapse of a Reinforced Concrete-Framed Structure Using Capacity Curves, Arabian Journal for Science and Engineering, 2019, Catalin Baciu, Marin Lupoae, George Bogdan Nica & Daniel Constantin

    Abstract: In the present paper, the potential of the progressive collapse of a reinforced concrete frame of a seven-storey building was evaluated by comparing the capacity curve and the M–N diagram of the beams. The advantage of this approach is that it captures the exact resistance mechanisms occurring during the progressive collapse of the structure such as flexural action, compressive arch action and catenary action. Furthermore, the overlapping of the capacity curves and the M–N diagram were proved to be an efficient tool to optimize the design of the resistance of structures to collapse. The modelling technique based on the Applied Element Method was validated by an experimental test. Consequently, numerical studies were performed according to General Services Administration guidelines using different scenarios implying the removal of one or two adjacent columns from the ground level. Additionally, the slabs were considered in the structural analysis and flexural action was identified as the main mechanism of action against total structural failure.

    Abstract: Nowadays, the data network area offers a very wide range of data switching techniques according to user needs. The current paper is concerned with a new broadband solution, namely the use of an MPLS-Internet VPN hybrid network. Even though MPLS is the basic solution in most private transport networks, with the explosive growth of the Internet, it has begun to be an alternative solution for data transmission. The purpose of this study is to balance the advantages and disadvantages of implementing this solution by bringing arguments on both sides and, finally, to draw an objective conclusion as to its applicability.

  1. Model and Algorithms for Optimizing a Human Computing System Oriented to Knowledge Extraction by Use of Crowdsourcing, 13th International Conference on Communications, Bucharest, 2020, Florin Enache, Victor Greu, Petrică Ciotîrnae, Florin Popescu

    Abstract: The paper is addressing the actual context of Data Deluge, where the need and also premises to extract more knowledge are increasing, along with the increase of our expectations about performances. Besides, improving artificial intelligence (AI), by machine learning (ML), deep learning (DL) or cognitive learning (CL) performance/potential, when adding human contributions where necessary, is an important and promising research area. Consequently, our model, algorithms (ALG1; ALG2) and soft programs provide useful new instruments for implementing and optimizing the workflow based on crowdsourcing, when using human potential in a human computing system. We aim to increase AI quality adding multiple human outputs for every AI task and leveraging learning rules to be then extended to larger sets of tasks. This way, such hybrid system could be oriented to more knowledge extraction, by the generalization of images/ captions/labels toward more complex tasks, like providing content essential or question answering. Our instruments include features of ranking workers and tasks profiles, which will support the main original process of knowledge extraction, but also the inference elements, by small amounts of learning data (regarding the workers skills and tasks efficiency) to be transferred to AI/ML/DL/CL, which then could be used for processing larger volumes of similar data. Among the results conclusions is that using progressive optimization, structuring the data/tasks in variable (progressive) sets and potential (skill/number) of workers, is both efficacious and efficient, allowing a flexible control of the system and workflow for matching a diversity of tasks complexity/ difficulty/volume and leveraging knowledge extraction.

    Abstract: The solution of distributing data between multiple sites over public networks is a solution that most companies value more and more. This strategy is justified by its multiple advantages, particularly in terms of data availability. However, the intermediary network through which these operations are carried out is often the Internet. No one can deny that this network does not provide any mechanism of privacy, integrity, or authentication. The purpose of this paper is to analyze the key performance indicators (KPI) of a Voice over IP network that crosses a public network using VPN (Virtual Private Network) technology.
