    Mechanization in agriculture & Conserving of the resources, Vol. 66 (2022), Issue 3, pg(s) 103-104

    Researchers monitor rivers and springs to predict what part of the water resources to use for irrigation for industry, drinking needs to maintain ecosystems. The main task of the scientific staff is to monitor and control the water quantities coming out freely from natural caverns, rock crevices, free-flowing rivers and springs. The measurements of kinematic quantities, can serve not only for the quantitative evaluation of the runoff, but also for the verification of the theoretically derived hydraulic dependencies in the different forms of water movement. When determining the water quantities, observations of the runoff are carried out, as well as the measured parameters can serve to play an important role in the construction of water management facilities

    Mechanization in agriculture & Conserving of the resources, Vol. 66 (2022), Issue 2, pg(s) 81-82

    The protection of soils and waters is an extremely important issue for humanity. The main task to be done by the scientific staff is to monitor and control the water quantities leaving the water management facilities. Measurements of kinematic quantities can be used not only for quantitative assessment of runoff, but also for verification of theoretically derived hydraulic dependency in different forms of water movement. They are the basis for experimental determination of a number of theoretically introduced coefficients measurement of the hydraulic quantities determining them. Hydro metric measurement of non-pressure currents is a specific activity that has gained wide application around the world. When determining the water quantities, observations of the river outflow are made, also the measured parameters can be used for other engineering tasks in the construction of hydro technical facilities.[1]


    Possibilities for application of sediment microbial fuel cells as biosensors for monitoring of recurrent water pollution with copper

    Industry 4.0, Vol. 7 (2022), Issue 3, pg(s) 114-117

    Sediment microbial fuel cells (SMFCs) are special microbial fuel cells in which the anode is placed in the anaerobic sediment and the cathode is immersed in the surface layer of water. Natural electroactive bacteria decompose organic compounds in sediment, producing electrons and protons. The electrons reach the cathode through an external electrical circuit, while the protons pa ss through the soil layer, which acts as a kind of membrane. Oxygen is in many cases the preferred electron acceptor due to i ts presence in the cathode region and its high potential. Heavy metal ions and other compounds can also be reduced on the cathode, which will increase the energy generated. Based on the above characteristics, SMFCs would be suitable for application as biosensors and would be suitable for monitoring recurrent water pollution with heavy metals. In the present study, the possibility of application of SMFCs as biosensors for recurrent water pollution with copper has been studied. A high correlation was found between the concentration of copper ions and the voltage generated by SMFC, as the coefficient of determination reached 0.9921.

    Security & Future, Vol. 5 (2021), Issue 1, pg(s) 14-17

    In the past years, NATO member countries have faced the threat of bioterrorism, which requires the development of capabilities to deal with this threat. Timely detection and accurate identification of the type of bioagent used is essential for early wa rning of threatened military units, as part of the process of prevention and reduction of human casualties, as well as for the spread of the disease. The possible use of biological agents as weapons of mass destruction (WMD) is presented in the report. The military reconnaissance role in the process of investigation of disease outbreak is considered. For the implementation of the process for early warning and alert of biological threat, a scheme of a model of a platform for biological reconnaissance and monitoring is presented. In the model a configuration of hardware and software is used. Due to the increasing risk of use of biological weapons by terrorist organizations, the acquisition and integration of an advanced platform for monitoring and outbreak reconnaissance from the units of the Armed Forces of the Republic of Bulgaria is of key importance.


    Information-measuring system for monitoring the sanitary condition of tree stands

    Industry 4.0, Vol. 5 (2020), Issue 3, pg(s) 142-147

    The article presents the results of the development of an information-measuring system for monitoring the sanitary status of tree stands. The main purpose of such a system is to minimize the impact of the operator on the results of monitoring the sanitary status of tree stands by indirectly controlling the quality characteristics of the tree sap (by establishing the dependence of these characteristics on climatic factors) with the possibility of remote monitoring and control of the process of express control. The developed monitoring system allows to conduct a contactless (remote) survey of sensors, which are recorded in close proximity to the root system of selective trees from an array of tree plantations, and further, by mathematical treatment of climatic characteristics (acidity and salinity index, air temperature) zoning temperature health status. The system also allows you to predict the dynamics of extending the areas of tree planting. This enables those responsible for tree planting to take preventative measures to prevent such droughts. The main advantage of the developed information measurement system is its complete computerization, which eliminates a number of external subjective influences by the operator or the responsible person (necessity of visual inspection of the maximum number of trees in the array, erroneous perception of visual information, etc.). This, in turn, avoids systematic methodological errors, thereby improving the accuracy, speed and reliability of the monitoring and control results of this system.


    Real-time urban air pollution monitoring using unmanned aerial vehicles

    Innovations, Vol. 8 (2020), Issue 1, pg(s) 29-32

    Measuring pollutant gases for real-time air quality monitoring is a challenging task that claims a lot of time of observation and large numbers of sensors [1]. Unmanned Aerial Vehicles (UAVs) equipped with different micro-sensors have been introduced for air quality monitoring, as they can offer new approaches and research opportunities in air pollution and emission monitoring instead of ground-based monitoring systems [2]. UAVs with mobile monitoring devices are an effective, flexible and alternative mean to collect air pollutant concentration data [3]. Hence, deployment of a fleet of UAVs could be considered as an acceptable alternative for the purpose of air monitoring [4]. The aim of this paper is to elaborate performance capabilities of UAVs for effective monitoring of air pollution, providing the ability to measure air pollutants with high sensitivities.

  • Monitoring and control of cyber-physical systems – the backbone of Industry 4.0

    Industry 4.0, Vol. 3 (2018), Issue 4, pg(s) 155-157

    Monitoring and control of Cyber-Physical Systems (CPS) have many challenges related to the heterogeneous environment, the high degree of interaction between the components and the high requirements for functionality and scale. The paper presents an analysis of the state of the art in this area and proposes an approach for monitoring and control of CPS through the integration of the IEC-61499 based models for distributed control systems and the IEC-61512 standard providing domain specific models for design and control of batch production processes as well as the Signal- Interpreted Petri Nets used for the purpose of formal specification and verification of unit procedures. The approach is illustrated with an example of CPS for loading a batch tank and mixing of liquid flow.

    Fish like many living organisms have specific tolerant range of various environmental parameters, thus fish farming of specific types of fish species requires certain conditions that have to be reached. Moreover, the people that work in the fish farming ponds have to be engaged in all day activities to maintain the living fish habitat. Therefore, monitoring and taking actions to maintain the habitat’s sustainable environment for certain fish species inside of fishing ponds over distributed machine to machine communication, which will shorten the time needed for some basic actions, is the main motivation for this paper. In this paper we present an upgrade on a functional Internet of Things (IoT) system for monitoring fish farming ponds. The IoT system consists of various sensors that measure important factors of the water quality like temperature, light intensity or water level, as well as small board computer that processes the data and sends sound and visual notifications to the fish farming manager. The current system lacks the ability to process the data to the end-user via web or mobile platform. Due to remote distance of the fish farming ponds and their location dependence of clean fresh water, one solution of this problem is using expansion module like Wivity modem to enable the end users in real time to monitor and control certain aspects of the fish farming pond IoT system. Wivity modem allows user to communicate to the IoT system via WiFi connection, cellular, LoRaWAN or satellite communication; all in one product. Later on, this module can be integrated with IoT platforms including Japser, Microsoft Azure or Amazon Web Services. For future work, we plan to expand not only the applicable services on different platforms, but also add more control modules and sensors to the existing IoT system for specific fish species.
