  • 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.

    WATER MONITORING IOT SYSTEM FOR FISH FARMING PONDS

    Industry 4.0, Vol. 3 (2018), Issue 2, pg(s) 77-79

    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.

    MONITORING OF THE NATURAL RADIOACTIVE FUND AND RADIOACTIVE POLLUTION – AN IMPORTANT FACTOR OF NUCLEAR SECURITY IN BULGARIA

    Security & Future, Vol. 1 (2017), Issue 3, pg(s) 125-128

    The radioactive contamination has actual national and international importance. It is related to the increasing the prevention measures of accidents as consequences of exploring the nuclear energy for peaceful purposes, and in the military purposes as well. The optimization and management of operational systems for monitoring of radioactive background should bring the increasing of nuclear Bulgarian safety, and the quality of the population defense from expose to radiation, as a consequence of changing the characteristics of the natural radioactive background.

  • CONSERVING OF THE RESOURCES

    MONITORING OF WEEDS IN CROPS OF LEGUMES AND CEREALS GROWN UNDER CONDITIONS OF ORGANIC FARMING

    Mechanization in agriculture & Conserving of the resources, Vol. 63 (2017), Issue 6, pg(s) 256-260

    During the period 2011 – 2013 a field experiment was conducted at the experimental field of IASS “Obraztsov chiflik” – Ruse, with ecologically grounded crop rotation, including the cultivation of two legumes /field beans, peas/ and two cereals /wheat, malting barley/ on an area after conversion. The experiment started after the eightfold scheme of Georges Ville in 3 replications, situated after Ryumker, the size of the harvesting plot being 52,5m2. Pesticides were not applied on the crops, also and synthetic fertilizers and improversof soil, prohibited for the organic production.

    The objective of the study was to observe and describe the biological regulation of weeds in legumes and cereals, grown under conditions of organic farming.

    In the organic field, the diversity of weed species was influenced by climatic conditions, soil tillage and crops. There were differences in weed infestation of crops only in terms of quantity of weeds per m2. In that case the differences in weed infestation were in direct relationship with certain biological characteristics of the crops. The species Matricaria chamomilla (L.), Anthemis arvensis (L), Capsella bursa-pastoris (L.), Setaria viridis (L.), Echinochloa crusgalli (L.), Digitaria sanguinale (L.), Lamium purpureum (L.), Convolvulus arvensis (L.) и Cirsium arvense(L.) were reported over the whole three-year period.

  • MONITORING PROGRAM FOR NON-MOTORIZED TRANSPORT IN THE CITY OF SKOPJE

    Machines. Technologies. Materials., Vol. 10 (2016), Issue 4, pg(s) 59-62

    Information about non-motorized transport, i.e., cycling and walking, are needed for planning and management support of urban transport systems. However, in the city of Skopje, monitoring programs still aren’t established by transport officials on regular basis. Hence, transport planners and researchers lack bicycle and pedestrian counts for managing traffic demand. Having in mind principles for comprehensive monitoring as a framework for assessment, this paper summarizes approaches and recommendations for initiating monitoring program in the city of Skopje. Also, describes steps in establishing monitoring program and identifies possible application of the analyzed monitored data for non-motorized transport.

    Software project management encompasses the knowledge, techniques and tools necessary to manage the development of software products. Software project management remains different from project management in other more established fields for a number of reasons. Software is “brain product” only, unconstrained by the laws of physics or by the limits of manufacturing processes. In the report discusses topics that managers need to create a plan for software development using effective estimation of size and to execute the plan with attention to productivity and quality.
