Despite of obstacles like battery life problems and practical implementation issues with charging stations, which might alter drone operations in the future with better recharging techniques and greater performances, work is still ongoing. Over time, these recharging station technologies improved. Intelligent features cut down on downtime. These stations also provide maintenance during non-use periods for batteries. It is a significant advancement for UAVs. Initial costs increase, but there may be benefits. Another major advantage is the charging station coil will be charged through solar power.
Recognizing Human Emotions Through Body Posture Dynamics Using Deep Neural Networks † Arunnehru Jawaharlalnehru, Thalapathiraj Sambandham, Dhanasekar Ravikumar Engineering Proceedings, 2025 Body posture dynamics have garnered significant attention in recent years due to their critical role in understanding the emotional states conveyed through human movements during social interactions. Emotions are typically expressed through facial expressions, voice, gait, posture, and overall body dynamics. Among these, body posture provides subtle yet essential cues about emotional states. However, predicting an individual’s gait and posture dynamics poses challenges, given the complexity of human body movement, which involves numerous degrees of freedom compared to facial expressions. Moreover, unlike static facial expressions, body dynamics are inherently fluid and continuously evolving. This paper presents an effective method for recognizing 17 micro-emotions by analyzing kinematic features from the GEMEP dataset using video-based motion capture. We specifically focus on upper body posture dynamics (skeleton points and angle), capturing movement patterns and their dynamic range over time. Our approach addresses the complexity of recognizing emotions from posture and gait by focusing on key elements of kinematic gesture analysis. The experimental results demonstrate the effectiveness of the proposed model, achieving a high accuracy rate of 91.48% for angle metric + DNN and 93.89% for distance + DNN on the GEMEP dataset using a deep neural network (DNN). These findings highlight the potential for our model to advance posture-based emotion recognition, particularly in applications where human body dynamics distance and angle are key indicators of emotional states.

A Reduced Switch Series Topology 15-level and 27level Multilevel Inverter S Vetrivel, S Ganesh Kumar, L Vijayaraja, R Dhanasekar 2025 IEEE Energy Conversion Congress and Exposition Asia Shaping A Greener Future with Power Electronics Ecce Asia 2025, 2025 In the fast-evolving technological advancements in the power conversion from DC to AC, multilevel inverters play a pivotal role in obtaining signals with less harmonic distortion. Reduced switch topologies of multilevel inverters are known for their flexibility in synthesizing several levels of voltages with less no. of switches, sources and diodes which greatly reduces the size of the device. This paper investigates the performance of nearest level control pulse width modulation (PWM) based series topology of Asymmetrical 15-level and 27-level Multilevel Inverter with R, RL load. The total harmonic distortion (THD) of the voltages and currents of R, RL load was found to be under the IEEE 519-2022 standards. The proposed model has been simulated in the MATLAB/Simulink simulation environment and the results have been analysed using the FFT analyser of the MATLAB.
IoT Enabled Optimization of Peltier Based Atmospheric Water Generation Techniques for Sustainable Water Harvesting R. Dhanasekar, B. Benita Evangeline, M. Shanmathi, A. Suvedha Proceedings of 8th International Conference on Trends in Electronics and Informatics Icoei 2025, 2025 Water scarcity is an increasing global challenge, making it necessary to discover suitable solutions to generate pure drinking water. An atmospheric water generator (A WG) uses electricity to capture humidity from the air and condense it into portable water. Multi-stage air filtration and UV water purification are used to ensure quality of the water, and the Peltier module helps with condensation. To optimize performance, real time monitoring is critical. Sensors for temperature, humidity, and water levels track atmospheric conditions, delivering instant data on fluctuations in thermoelectric cooling, enhanced filtration, and intelligent monitoring, this type of technology not only boost quantity of water production but also enhances energy efficiency of the module. As a result, A WGs present a sustainable and reliable strategy to address the escalating water crisis.
Leveraging RFID for Road Safety Sign Detection to Enhance Efficiency and Notify Drivers † Dhanasekar Ravikumar, Vijayaraja Loganathan, Pranav Ponnovian, Vignesh Loganathan, Bharanidharan Sivalingam Engineering Proceedings, 2025 Road safety signboards are now difficult to see due to pollution and harsh weather elements such as snow and fog, which has resulted in more accidents. The problem is especially common in Western countries where snow can block these critical signs. An approach addressing this issue involves a system that uses Radio Frequency Identification (RFID) and Internet of Things (IoT). The real-time alerts that this system sends to drivers improve driver safety in complex environments. For this purpose, an RFID reader is placed in the vehicle, and passive RFID tags are attached to road safety signboards. The reader picks up the signal as a vehicle comes within range, and the warning for the vehicle is sent to the driver. It helps to reduce the number of accidents resulting from poor visibility. In addition, because its multi-lingual audio alerts the drive through speakers and visual warnings displayed on a display screen, the system is accessible to drivers from various regions. To make the system more sustainable, we added some solar panels to the system to cut costs as far as energy efficiency is concerned. The system combines GPS and GSM modules to provide the vehicle position in real time in the cloud. It gives better warnings and helps avoid accidents. In addition to improving road safety, the system offers support for the environment, by limiting emissions and waste of resources caused by accidents. Traffic patterns can thus be studied with the data, creating more efficient and ecofriendly transportation systems. This solution enables a smarter vehicle network that is safer and more sustainable with quick, accurate alerts.
Innovative Crack Detection Approach Using UAV-Based Imaging Technology R. Dhanasekar, Pranav P, Vignesh. L, Bharanidharan. S, Abhijith. M S 2025 International Conference on Computing and Communication Technologies Iccct 2025, 2025 The Aging Road bridges impart a serious threat that must be addressed by estimating the health of the bridges manually. This paper presents a novel approach for crack detection in road bridge by using Unmanned Aerial Vehicles (UAVs). Traditional bridge inspection methods prove to be time consuming, expensive and have inaccessible areas. UAVs equipped with CNN trained model, high-resolution cameras, and sensors offer safe and secure ways to inspect the bridge health. This paper explores the integration of deep learning models with the UAVs in detecting cracks of a bridge which offers valuable insights on the health of a road bridge. The CNN model is trained with a dataset of 5000 images for each label, namely Positive and negative. The results establish an accuracy of more than 97 percent. This paper further emphasizes the potential of UAVs and crack detection for infrastructure maintenance, offering real-time data to support repairs and improve long term bridge health.
A Comparative Analysis of Various Mppt Techniques Coupled With DC-DC Converters Feed With BLDC Motor in Photovoltaic Systems S. Rajarajan, R. Dhanasekar, S. Dhanushkumar, D. Somesh, G. Aswin, S. Santhoshkumar Proceedings of 2025 International Conference on Signal Processing Computation Electronics Power and Telecommunication Iconscept 2025, 2025 As energy needs grow steadily worldwide, the demand for non-polluting and sustainable energy resources is becoming more important. Solar power is an effective renewable solution since it is plentiful, pollution -free, and sustainable over the long run. Improving system efficiency requires efficient power conversion techniques and suitable DC-DC converter units. This paper performs a comparative performance study of the Perturb and Observe (P&O) and Incremental Conductance (INC) MPPT algorithms applied to two DC-DC converter topologies, Quadratic Boost Converter (QBC) and Conventional Boost Converter in a PV based system supplying a BLDC motor. MATLAB/Simulink is used to simulate the proposed system with a BLDC motor load, and performance parameters such as efficiency, voltage ripple, MPPT response time and motor speed stability are analyzed.
Design and Implementation of Novel Dynamic Voltage Restorer Configuration for Electric Vehicle Charging Applications † Kesav Sanadhan Saikumar, Thenmozhi Mutharasan, Vijayaraja Loganathan, Dhanasekar Ravikumar, Vishal Thirumalai Nambi, Sudhesh Kumar Ezhilarasan Engineering Proceedings, 2025 Electric vehicles are replacing conventional vehicles in today’s world due to their eco-friendly operation and reduced maintenance. Although EVs offer advantages over conventional vehicles, there is a limited number of charging stations, and numerous power quality issues have emerged at these locations. This is due to the voltage, current, or frequencies being abnormal, which leads to sudden voltage drops, voltage swells, long interruptions, and short interruptions occurring at the charging stations. To address issues arising from client-side anomalies, we attach conventional FACTS devices closer to the load end. One such dependable custom power gadget for dealing with voltage sag is the one developed in this article, and it is called an enhanced dynamic voltage restorer (DVR). The proposed device continuously monitors the load voltage waveform and injects (or absorbs) the balance (or surplus) voltage into (or away from) the load voltage whenever a sag occurs. We develop a reference voltage waveform to achieve the aforementioned capabilities. In this paper, the methods of compensation for these problems at charging stations are discussed. Furthermore, the power quality problems are compensated for by the proposed system using an SVPWM controller. Simulation and real-time implementation are carried out, and the results are discussed. The inclusion of SVPWM control significantly improves voltage regulation and reduces THD by 60–70% compared to conventional PWM methods, which achieve only 40–50% reduction. The proposed DVR is designed for single-phase applications, making it suitable for low-voltage distribution systems and sensitive industrial loads. The proposed model provides a rapid response time (<10 ms), and the efficiency of the proposed DVR is found to be 92%, which is greater than that of conventional designs (86%).
