The ability to directly control external equipment using electrical impulses to translate brain activity into commands or information has made brain-computer interfaces (BCI) an increasingly relevant research topic. Numerous uses for this technology have been discovered, including cursor control, wheelchair navigation, and use in diverse sectors. In this paper, a unique EEGNet-inspired Multi-Scale architecture is proposed, which is intended to boost Rapid Serial Visual Presentation (RSVP) task categorization performance. The performance of our suggested architecture is assessed using the datasets from BCI Competitions II and III, and accuracy of 76.3%, 84.2%, and 90.5% is achieved for subjects II-A, II-B, and IIb, respectively. The average symbols recognized under repetition metric is also used to evaluate the proposed architecture. These results show a notable improvement in accuracy and other evaluation metrics compared to previous research. Overall, the proposed architecture advances the field of BCI technology and offers a fresh, potentially effective method for enhancing RSVP categorization task performance. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

This paper presents an acausal modeling approach for developing a hydrodynamic module in the control-oriented, Reconfigurable, and Acausal Floating Turbine Simulator (CRAFTS), a wind turbine simulation tool being developed by the authors, to facilitate control co-design of floating offshore wind turbines (FOWTs). The available data of the semi-submersible VolturnUS-S FOWT is incorporated into the modeling, simulation, and control demonstrations. The model is verified and validated using numerical data from industrial-standard simulation platform OpenFAST and experimental data from the Floating Offshore-wind and controls Advanced Laboratory (FOCAL) Project. Numerical results demonstrate that the hydrodynamic module in CRAFTS can qualitatively capture loads and responses from the free decay tests, as well as the stabilizing effects of the tuned mass dampers (TMDs), which are tuned to attenuate the platform pitch resonance or the tower bending resonance.

A versatile leg-wheel robot called STransleg is proposed in this paper. STransleg is propelled by four identical leg-wheel mechanisms, which can transform between the legged and wheeled modes. The leg has three active joints in the legged mode, and the wheel is active in the wheeled mode. The waist yaw and pitch joints are introduced to STransleg to improve the locomotion flexibility and stability. In this paper, the design and kinematics modeling methods of STransleg are described. Additionally, the control method is proposed for STransleg to make it do the four-wheeled locomotion, walking locomotion, and carriage-like locomotion. The simulations are carried out to make the dynamical model of STransleg do the different locomotion, and the results verify the feasibility of the robot design method and the proposed control method.

This paper presents the design of a compliant mechanism for secondary positioning actuation within a dual-stage three-dimensional (3D) -printer. Dual-stage structures consist of a low-speed, long-range actuator that displaces a serially-connected high-speed, short-range actuator. This work focuses on the mechanical design of the secondary planar actuator: a compliant mechanism guiding the motion of voice coil motors. The stiffness and range characteristics are tailored to compliment the long-range gantry positioner of the system, while achieving a mechanical bandwidth over 10x larger. Euler-Bernoulli beam theory with Castigliano's second theorem are leveraged to determine the effective stiffness of the mechanism;finite element analysis (FEA) is used to estimate the range and speed characteristics of the mechanism. A prototype positioner is manufactured via 3D -printing, and the experimental system is characterized. Simulations are performed on a linear model of the system using PID control with a complementary filter pair.

In order to solve the problems of classical convolutional neural networks in coal and gangue recognition, such as large calculation amounts, slow recognition speeds, and low recognition accuracy, a method for coal and gangue recognition based on an improved MobileNetV3 network is proposed. Based on the MobileNetV3 model, the activation function and attention mechanism were improved and the number of network layers was reduced. Finally, the accuracy rate, F1 score, and floating-point operation (FLOPs) were used as the benchmark for model evaluation. The results showed that: The test accuracy rate after the improved MobileNetV3 is 99.5%, the F1 score is 0.995, and FLOPs is 50455003. A comparison between the model and the MobileNetV3, EfficientNet, and AlexNet models shows that all indicators of the model are higher than those of other models. Suitable for coal gangue recognition model.

Transmission system forms the backbone of any electrical power system. Transmission systems are exposed to environment and prone to fault. Therefore, chances of unwanted event resulting in large scale blackouts can never be ruled out. Renewable integration has increased the vulnerability of power system. Therefore, over the year resilience is gaining more and more importance for power system planners. Many grid codes have implicit provision of resilience. Key features of a resilient power system are robust islanding scheme and adequate number of black start resources. When a large power system fails to operate in synchronism, it becomes preferable to create small islands as the surviving islands make the restoration process fast. Success of an islanding scheme depends on the design as well as implementation of the logic. Logic needs to be robust as well as simple. Extensive study is required to design an effective islanding scheme. For islanding scheme design various preliminary studies are done and the results are discussed in the paper. The purpose of the studies was solely to check the frequency stability of the island. These islanding logic needs to be designed purely based on frequency logic and no under voltage logic to be used. This is because these islands are designed for supply of capital city, only in case of total or partial grid failure. Therefore, here island scheme design only aims at arriving frequency setting and load shedding scheme design inside the island. However, these studies are done based on certain assumption which will also be discussed in the paper. Its purpose is to check the broader feasibility of an islanding scheme. The final islanding logic may be finalized by the respective generating plants in consultation with their OEMs. The governor of a generating unit has a vital role to play in the success of the islanding. Currently in Indian power system restricted governor mode of operation (RGMO) is in service for generators [1]. In this

Depression is a common mental illness characterized by symptoms such as low mood, pessimism, and insomnia. In this study, we developed a deep Dual-Stream CNN to automatically diagnose and classify depression in expression video sequences. The network has two branches that extract static features and dynamic features from static and dynamic expressions, respectively, which are then fused for depression classification. The experiments were performed on the AVEC2014 database, and the results showed that the Dual-Stream model significantly improved the classification performance of depression, achieving an accuracy of 69.08% in depression categorization. © 2023 SPIE.

A substation is the most important component of transporting or distributing electricity in any region or industry. To control and monitor the substation, different automation structures are developed in our country and around the world. The proposed system is to develop an IoT-based smart solution for monitoring and controlling the transformer in a substation. The control unit serves as the hub for all the system equipment and activities. Using an ultrasonic sensor and the DHT11, this smart solution can monitor transformer oil and temperatures. When the temperature of the transformer climbs over the specified value, the cooling fan turns on and provides sufficient air to lower the temperature. The voltage and current sensors' collected data determine whether the circuit is open or closed. This eliminates the expense at the substation by minimizing operating costs. As a result, both observational and operational effectiveness will undoubtedly improve.

In this paper, a deterministic mathematical model of cancer cell dynamics is considered. We propose a new method to simulate and control the growth of tumor cells, as well as immunotherapy and chemotherapy for patients. The model is a coupled Ordinary Differential Equation (ODEs) that describes the growth of cancer at a cellular population level in the presence of a combination of immunotherapy and chemotherapy called biochemotherapy. The model is formulated as an optimal control problem with the objective of obtaining the optimum levels of each of the treatments that must be used to decrease the rate of growth of cancer cells, and to minimize the use of chemotherapeutic agents and immunotherapy drugs while maximizing the performance of the immune system. Based on Pontryagin's Maximum Principle, the optimal control system is deduced, and the solution is obtained. The results of the simulation show that biological chemotherapy can significantly reduce the cancer cell growth in a reasonably short time. © The Institution of engineering & Technology 2023.

Synchronization units are vital for the stable operation of grid-tied converters in generation and transmission. There are two main synchronization units, i.e., phase-locked loop (PLL) and power synchronization controller (PSC), with the corresponding drawbacks in weak and strong grid respectively. Recently, the hybrid synchronization controller (HSC) is proposed in order to make up the deficiencies of PLL and PSC in weak and strong grid respectively. This paper deduces the detailed impedance characteristics of PSC and HSC and compares their cons and pros to show the stability mechanism of HSC. Moreover, two types of HSCs are also presented and compared in this article with slight difference in structure. It is found that the impedance of Type II based HSC has smaller amplitude and better phase margin than PSC around fundamental frequency, while Type I based HSC has larger amplitude and less phase margin than PSC. Type II based HSC can improve the stability and Type I based HSC can worsen the stability compared with PSC. Realtime experiments are carried out to verify this. (c) 2023 Published by Elsevier Ltd.
