An Approach to the Collision Detection of Non-SOLAS Vessels Using the Concept of e-Navigation Igor Stanovčić, Milutin Radonjić, Enis Kočan, Božidar Škrbić, Božo Krstajić 2024 28th International Conference on Information Technology IT 2024, 2024 This paper presents a proposal for the approach to potential collision detection of non-SOLAS vessels using an e-navigation system based on modern IoT systems. Although there are significantly more non-SOLAS vessels than SOLAS vessels worldwide, the lack of basic navigation equipment excludes them from the navigation safety system. The implementation of the proposed innovative IoT concept and the described architecture, using available smart devices, would significantly increase the navigation safety of non-SOLAS vessels, and thus the overall safety at sea.
A Path Towards an Internet of Things and Artificial Intelligence Regulatory Framework Suada Hadzovic, Sasa Mrdovic, Milutin Radonjic IEEE Communications Magazine, 2023 As technology is the driver of the economy, it is necessary to follow emerging technological trends and to create appropriate conditions for its adoption and implementation as a human-centred technology. In this regard, rules and standards for the Internet of Things (IoT) and Artificial Intelligence (AI) should be established to best use the benefits of technology and to prevent or minimize the consequences of technology misuse. The fifth industrial revolution (Industry 5.0) has already begun, although Industry 4.0 is still developing. Consequently, the original attention has shifted from IoT to AI, with the IoT debate now being a prerequisite for the AI debate. As AI is transforming our lives, a growing number of countries have considered or already adopted national AI strategies. However, in many developing countries, national AI strategies and initiatives for establishing AI and IoT regulation and legislation frameworks yet need to be discussed. The subject of this article is the research of existing initiatives related to establishing the IoT and AI regulatory and legislative framework in the EU and its applicability in developing countries.
Proposal for Improved Navigation Safety of Non Solas Vessels by Combining TSS And IoT Technology Igor Stanovčić, Rino Bošnjak, Milutin Radonjić, Božo Krstajić 2023 27th International Conference on Information Technology IT 2023, 2023 This paper presents the concept of increasing navigation safety, especially from the point of view of Non SOLAS vessels and in areas with limited navigation space. The concept consists of a symbiosis of the traditional Traffic Separation Scheme with the concept of E-navigation and VTS as a service provider. The idea is that Non SOLAS vessels, using smartphones with the appropriate application and IoT cloud platform (server and appropriate software), become identified by other vessels and VTS.
An IoT System for Real-Time Monitoring of DC Motor Overload Milutin Radonjić, Žarko Zečević, Božo Krstajić Electronics Switzerland, 2022 The excavators are heavy machines widely used in the civil engineering and surface mining industry. Recent studies show that 95% of contractors face the problem of finding skilled operators. Unskilled operators not only worsen productivity but also very often cause machine failures through unprofessional handling. Motivated by these studies and guided by the mining company’s requirements, we present a prototype of an IoT system for monitoring DC motor overload on the EKG-15 excavator. The IoT system consists of a microprocessor device mounted inside the excavator and an external cloud platform that can be accessed via the Internet. The proposed solution detects and warns the operator when the DC motor overload occurs, thus reducing the probability of its damage. In addition, overload data is sent to the cloud platform for later research, analysis and processing. The main benefit of the proposed solution is that it can be applied to existing industry machinery, thus reducing the maintenance cost and increasing productivity. After several months of use of the proposed system in real working conditions, it has been shown that the overload occurrence and its duration time are approximately reduced by 60% and 80%, respectively.
IoT System for Detecting the Condition of Rotating Machines Based on Acoustic Signals Milutin Radonjić, Sanja Vujnović, Aleksandra Krstić, Žarko Zečević Applied Sciences Switzerland, 2022 Modern predictive maintenance techniques have been significantly improved with the development of Industrial Internet of Things solutions which have enabled easier collection and analysis of various data. Artificial intelligence-based algorithms in combination with modular interconnected architecture of sensors, devices and servers, have resulted in the development of intelligent maintenance systems which outperform most traditional machine maintenance approaches. In this paper, a novel acoustic-based IoT system for condition detection of rotating machines is proposed. The IoT device designed for this purpose is mobile and inexpensive and the algorithm developed for condition detection consists of a combination of discrete wavelet transform and neural networks, while a genetic algorithm is used to tune the necessary hyperparameters. The performance of this system has been tested in a real industrial setting, on different rotating machines, in an environment with strong acoustic pollution. The results show high accuracy of the algorithm, with an average F1 score of around 0.99 with tuned hyperparameters.
Sound-based logging detection using deep learning Budimir Andelic, Milutin Radonjic, Slobodan Djukanovic 2022 30th Telecommunications Forum Telfor 2022 Proceedings, 2022 Illegal logging represents a major environmental issue which impedes the stability of forest ecosystem and supports climate change, flooding, soil erosion, weeding of habitats, extinction of animal and plant species. This paper proposes a method for mitigating the logging issue by automatically detecting the sound of logging activities. More specifically, we propose to detect the chainsaw sound using deep learning. Two deep learning approaches were considered, one based on multilayer perception (MLP) and the other based on convolutional neural network (CNN). As inputs to our models, we used time, frequency and time-frequency audio features. For this research, we collected two datasets of audio signals. First dataset, downloaded from YouTube, is used for training and validating the proposed models. Second dataset, which we recorded in a real environment, is used for testing of the proposed models. The experiments have shown that the CNN-based approach outperforms the MLP-based one, with a sound classification accuracy of 94.96% on the first dataset and 88.87% on the second dataset.
Design of a kitchen-monitoring and decision-making system to support aal applications Nikola Žarić, Milutin Radonjić, Nikola Pavlićević, Sanja Paunović Žarić Sensors, 2021 Numerous researchers are working on Ambient Assisted Living systems to enable more comfortable and safer living for senior people in their homes. Due to modern lifestyles and an aging population, this has become a very important issue. According to the available literature, it is obvious that the kitchen is one of the most important and most dangerous rooms in the home. However, there is still evident lack of monitoring systems suitable for specific kitchen activities. In this paper, we propose a monitoring system capable of identifying activities related to the cooking process, and a decision-making system capable of identifying some unwanted and possibly critical conditions. The proposed systems are designed to satisfy the requirements of the modern Ambient Assisted Living systems dedicated to older adults. The proposed monitoring system consists of ultrasound, temperature, and humidity sensors. The acquired results from these sensors are the inputs for the decision-making system, which generate warnings or alarms intended for the senior users and/or formal or informal caregivers. This system is designed to improve home safety related to kitchen activities, as well as to provide information about the lifestyle and daily activities of senior users. Experimental validation of the proposed system confirms its functionality and accurate design approach.
Identification of IoT actors Suada Hadzovic, Sasa Mrdovic, Milutin Radonjic Sensors, 2021 The Internet of Things (IoT) is a leading trend with numerous opportunities accompanied by advantages as well as disadvantages. Parallel with IoT development, significant privacy and personal data protection challenges are also growing. In this regard, the General Data Protection Regulation (GDPR) is often considered the world’s strongest set of data protection rules and has proven to be a catalyst for many countries around the world. The concepts and interaction of the data controller, the joint controllers, and the data processor play a key role in the implementation of the GDPR. Therefore, clarifying the blurred IoT actors’ relationships to determine corresponding responsibilities is necessary. Given the IoT transformation reflected in shifting computing power from cloud to the edge, in this research we have considered how these computing paradigms are affecting IoT actors. In this regard, we have introduced identification of IoT actors according to a new five-computing layer IoT model based on the cloud, fog, edge, mist, and dew computing. Our conclusion is that identifying IoT actors in the light of the corresponding IoT data manager roles could be useful in determining the responsibilities of IoT actors for their compliance with data protection and privacy rules.
