Telesurgery using robotic arms equipped with artificial intelligence represents an innovative direction in the field of neurosurgery, with the potential to improve the precision and efficiency of brain interventions. The purpose of the present study is to analyze the advantages and challenges of this technology, as well as future development directions. The methodology employed involves a systematic analysis of the relevant literature from the last five years. The results suggest that telesurgery using the artificial intelligence and robotic technologies in neurosurgery can facilitate more precise and less invasive interventions;however, there are challenges related to technological integration and clinical acceptance. Additionally, the feasibility of applying telesurgery in neurosurgical interventions is analyzed and discussed. The main conclusion of this study is that telesurgery with robotic arms featuring artificial intelligence has the potential to revolutionize surgical practices but requires further research to overcome current obstacles. © 2024, Cefin Publishing House.

This study proposes a redundant navigation system for UUV (Unmanned Underwater Vehicle) utilizing a 6 DOF (Degree of Freedom) VDM (Vehicle Dynamic Model). The system is designed to enable safe UUV asset return when all navigation sensors become inoperable. Since it is impossible to perfectly determine VDM coefficients through water tank experiments, a method to improve VDM output accuracy in real time during UUV mission is necessary. Here in this study, we introduce real-time adaptive 6 DOF VDM output error compensation algorithm to enhance the performance of redundant navigation systems. This research aims to establish the foundation for backup navigation solutions in situations when critical UUV sensor failures occur. © ICROS 2025.

In recent times, South Africa has been experiencing power outages, which has significant effect on businesses and economic wellbeing of the nation. To address this challenge, this study develops a maintenance framework that power-generating industries in South Africa can implement. Primary data was collected from company X that is a major subsidiary of the power generating industry in South Africa to probe the root causes of power outages in recent times. The analysis of the data obtained was carried out using Pareto chart. The results obtained identified delay in maintenance operations as one of the possible causes of power outages. The rework job was observed to be tardy by 50 days. This length of days is critical enough to cause power outage. To address this, a framework was developed to assist in effective scheduling of maintenance activities. Hence, this work provides an insight into the possible causes of power outages in South Africa and how they can be mitigated to avoid load shedding. © The Author(s) 2025.

Requirements on glass manufacturing with exceptionally high mechanical strength triggered development of new laser-based processing methods. Localized modifications produced by ultrashort pulsed lasers are attractive but may lead to micro-crack generation in glass. Aiming to control stresses during volumetric material modifications, we have studied the effect of pulse duration experimentally. Bessel beam shapes with arbitrary conical angles have been generated using a programmable spatial light modulator (SLM), while stresses have been monitored using time-resolved optical transmission and cross polarized microscopy. Pulse duration variation influences mechanical stress in the laser glass interaction, and we found the optimized pulse duration exists in the laser glass machining by pump-probe microscopy. © 2023 SPIE.

The shop floors require material, machinery, equipment and tools, information technology, quality control, storeroom, manpower resources for manufacturing of intermediate or final product and inventory management. In this study, an automated logistics and inventory management system was developed for shop floors to improve the production efficiency. A sensing system was developed based on the framework of Internet of things (IoT) to collect the information of copper-aluminum strip and polyvinyl chloride both in the storage room and manufacturing area, and an expert system was developed to automatically conduct inventory management based on the established rules. The experimental results showed that a large amount of working time is reduced, improving efficiency in manufacturing industries. The proposed system can reduce the time of recording data and also assist the manager in configuring and managing material orders. © 2024 IEEE.

A STUDY ON THE ENERGY CONSUMPTION OF A MECHATRONIC DELIVERY SYSTEM WITH A SPIRAL USED IN AN INNOVATIVE ENERGY-EFFICIENT VENDING MACHINE FOR URBAN USE

The innovative energy-efficient vending machine for use in urban environment, called SVIEE-R, have been developed in the global context of reducing energy consumption and using alternative energies. In the design and prototype building phase of the SVIEE-R we analysed energy consumption for several models of the product delivery subsystem. In order to optimise the energy consumption for the product delivery subsystem we also considered the mechatronic delivery system with a spiral for packaged products. Building an energy efficient mechatronic delivery system allows to increase the lifetime of energy independent vending machines and concerning vending machines supplied from the public electricity grid to reduce greenhouse gas emissions. The use of modern design software allowed the analyse of the functioning of the mechatronic spiral systems from the design stage. The paper presents the research undertaken for the energy efficiency of the mechatronic spiral system using simulations of the operation validated through functional tests using a stand made by modern manufacturing technologies (laser cutting, 3D printing). The tests carried out were mainly aimed at evaluating the energy consumption of mechatronic spiral delivery systems. © 2024, Cefin Publishing House. All rights reserved.

Display panels manufactured in the FAB process are assembled with various films and components in the module (MOD) process, and their final quality is a result of accumulated the quality of hundreds of preceding processes. Due to these limitations, it is hard to analyze the cause of MOD’s outliers relevant to the FAB process and much time and money are consumed to maintain the cause process to eliminate MOD outliers. Therefore, we propose a new explainable AI (XAI) approach to detect and improve the module process’s outliers by finding the correlation between FAB and MOD in this paper. The proposed approach was verified for MOD outlier cases in the real world’s OLED development and manufacturing process. As a result, it confirmed 96.8% of the average accuracy for classifications. This approach presents the FAB factor that caused MOD’s outliers based on the correlation between the MOD and the FAB. © 2023, John Wiley and Sons Inc. All rights reserved.

Wide band-gap devices are about to capture the power semiconductor market for electric vehicle applications since efficiency and power density are becoming more and more important. To gain highest efficiency in traction inverters, wide band-gap semiconductors can be used in 3-level structures. This paper deals with the switching behaviour of SiC-MOSFETs in an ANPC inverter with different modulation schemes by discussing switching processes of a scaled down experimental setup during operation. It shows the influence of secondary effects depending on the modulation scheme like additional parasitic turn-on losses, stray inductance in different commutation paths and the consequent loss distribution. © VDE VERLAG GMBH · Berlin · Offenbach.

Increasing dc-link voltage levels of battery electric vehicles implicate new requirements for traction inverters. Besides the application of higher-blocking wide-bandgap semiconductors, further technological solutions can contribute to highly efficient, low-cost inverter designs. 3-level inverters comprise the potential to improve future electric powertrains and thus need to be investigated concerning this application. This paper gives an overview over restrictions and opportunities of using a 3-level inverter in 800 V electric powertrains with focus on the ANPC structure. The discussed aspects include losses, harmonic performance, modulation, and especially the operation under fault condition. © 2023 The Korean Institute of Power Electronics.
