MODELLING A MASS-SPRING SYSTEM USING A SECOND-ORDER HOMOGENEOUS LINEAR ORDINARY DIFFERENTIAL EQUATION WITH CONSTANT COEFFICIENTS

2024-06-16T12:08:59+00:00

In this paper, a mass-spring system is considered. The system is modelled using a second-order homogeneous linear (ODE) with constant coefficients. Using this model, the behaviour of the system is studied. The most significant factor, the value of the damping, determines whether the case occurs: no damping, underdamping, critical damping, or overdamping. Each case is mathematically analysed to get particular parameters that impact how the motion system performs. The obtained solution, which demonstrates the behaviour of the system in a diagram plot of a displacement-time graph and a phase plane graph, is graphically presented in MATLAB software.

AUTOMATED PROCESSING LINE FOR EFFICIENT SORTING OF WASTE RECYCLABLE MATERIALS

2024-06-16T12:08:59+00:00

This paper is considering the implementation of a modern automated processing line designed to enhance the efficiency of waste material sorting. With a focus on delivering products of optimal quality and quantity within defined timeframes, the research uses a comprehensive methodology integrating advanced automation techniques. Through an examination of the complex dynamics inherent in sorting processes, the research not only addresses fundamental challenges in waste management understanding but also highlights positive environmental outcomes and promotes ecological integrity. The integration of automated systems not only aims to improve productivity and staff working conditions but also aligns with the imperative of promoting a more ecologically sustainable environment. The architectural layout of the facility is strategically organized into two specialized zones, including the reception area for waste intake and sorting and preprocessing section utilizing advanced technologies. These identified zones collectively form the backbone of the facility’s infrastructure, ensuring a systematic and effective approach to waste management.

AUTONOMOUS SOLUTIONS FOR DESIGN AND IMPLEMENTATION OF MODULAR STRUCTURES

2024-06-16T12:09:00+00:00

Our objective with this paper is to analyze and explore emerging autonomous solutions for designing and implementing modular structures. Modular structures have been in use since the 1950s, so the concept is not new to us. Historically, the popularity of modular structures peaked following catastrophic natural disasters or wars, in areas that required rapid rebuilding. However, modular construction somewhat fell out of favor afterward. Nowadays, its popularity is resurging, becoming a notable trend once again. The robots employed in modular construction offer distinct advantages over those used in traditional construction, with streamlined tasks and enhanced efficiency. In this paper, we plan to analyze drones, loaders, cranes, and worker bots. These robots will serve various roles, including observation, construction, organization, and excavation. Furthermore, we aim to integrate these robots with cutting-edge technologies such as artificial intelligence, augmented and virtual reality, the internet of things, cloud services, and building information modeling - BIM.

IMPLEMENTATION OF SCADA SYSTEM FOR REMOTE MONITORING AND POWER METERING IN RF AND IoT NETWORKS

2024-06-16T12:09:00+00:00

This paper represents the results of the development, design, and practical implementation of the SCADA monitoring power meter system. This power meter system is implemented in RF and IoT networks.The solution has been tasked with collecting, measuring, storing, and visualizing energydata (voltage, current, power, energy, reactive power, reactive energy, and power factor), as well as appropriate process data in two remote industrial plants. In the first plant, the first energy measuring point marked as the MASTER station is located, and in the second plant, the second energy measuring point marked as the SLAVE station is located. The SCADA monitoring system is built into the MASTER station. The SLAVE station is connected by RF (radio frequency connection) to the MASTER station. In the MASTER and SLAVE stations, two microcomputers and energy measurement units as well as appropriate RF modules are installed. The microcomputer in the MASTER station is serially connected to the IoT microcomputer for the transfer of measurement data in the Internet network. The solution provides visualization, data log file, and transfer to the IoT network of the energy and process data from the two measuring points.
