This paper studies highly scaled, multichannel MoS2 transistors (MCTs) through both experiments and simulations. A low-temperature MoS2 synthesis enables a novel integration scheme for MCTs on 8" wafers with self-aligned source/drain contacts, multiple gate-dielectric-MoS2 channel-dielectric-gate layers stacked on 8" Si wafers, reduced lithography steps and no sacrificial layers. A 1-channel, double-gate MoS2 transistor features 386 μA/μm on current (ION) at VDS=1 V, subthreshold swing SS = 85 mV/dec, and record performance among 2D gate-all-around (GAA) transistors and MCTs. A low drain-induced-barrier-lowering DIBL = 28 mV/V is also demonstrated. We also report the first functional high performance 2-channel MoS2 transistor with 673 μA/μm ION and 88 mV/dec SS at 400 nm channel length (LCh). In parallel, local-back gate transistors with 1.5 nm physical oxide thickness and 4 nm physical channel length were fabricated to calibrate the device model at extreme scales for design-technology co-optimization (DTCO). Thanks to the DTCO analysis, a projection of multi-channel transistor’s scaling, including power, and performance for "1 nm" technology node and beyond is presented. © 2024 IEEE.

The paper presents the implementation of a Switched Capacitor Power Amplifier (SCPA) to be integrated into a Narrowband Internet of Things (NB-IoT) Transceiver. The SCPA is designed to operate at a frequency of 0.9GHz and aiming the maximum output power allowed by the standard of 23dBm. All the blocks within the SCPA were developed using RF components of a standard 130nm CMOS process, with a 1.2V/2.4V supply voltage. Results show that the SCPA is able to produce a maximum output power of 15.61dBm with a maximum Power-Added Efficiency (PAE) of 26.52% and a Total Harmonic Distortion (THD) of 0.68%. The measured HD2 and HD3 are-70.23dBc and-43.41dBc, respectively. Additional Process, Voltage and Temperature (PVT) corners and Monte Carlo simulations indicate the SCPA operates properly when subject to different conditions and mismatches. Besides the SCPA, a 16 QAM modulation stage is designed in VerilogA in order to evaluate the performance of the RF PA when a sequence of symbols is transmitted. © 2023 IEEE.

Micro-robotic cell injection is a widely used procedure in cell biology where a small quantity of biological material is inserted into a cell using an automated or semi-automated micro-robotic system. Given its micro-scale nature, cell injection using a semi-automated micro-robotic system requires extremely high precision, hand-eye coordination, and depth perception for maneuvering the micro-pipette. As the cell injection is a laborious work, there is a dire need of rigorous training and a great deal of experience using live specimens and high-end microscopes. To facilitate this training, we have presented a paper in the past about modular virtual reality (VR) with basic simulation modules, here, the present work deals with the modelling of advanced training modules and experimenting of VR simulator. The proposed simulator includes: (i) Advanced training modules to train users on complete injection/suction procedures;(ii) The performance evaluation of the users using three metrics, i.e., (i) time, (ii) trajectory, and (iii) positioning accuracy is also integrated within the simulator;(iii) An experimental set-up has been developed for the face, content, and construct validity of the VR simulator. Finally, the effectiveness of the proposed simulator is validated by experts from the relevant domains and can be used for various applications like drug delivery, injection procedures and in-vitro fertilization. The experimental results demonstrated that a Virtual cell injection training simulator is feasible for the training of cell injection procedures and depicted that the injection success rate is 100% after using VR simulator. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2024.

This paper proposes a novel strategy to address the difficulties encountered in Botswana's open-pit mine dewatering procedures. The conventional approach, which relies on labor-intensive manual labor and mechanical switching, is expensive, time-consuming, and present significant safety hazards. To overcome these limitations, this project proposes a multi-sensor network system that automates and optimizes the dewatering process and improve operational efficiency. The system integrates real-time sensor data to monitor fuel consumption and water levels in mining pits, enabling precise pump operation control. The system has two sets of sensors for data collection on fuel levels in the reserve and dewatering pump tank. Water level sensors are also used to monitor the water levels in the tank and turn the pump on or off based on predetermined thresholds. After receiving the sensor data, a microcontroller controls the entire process and shows the fuel levels and consumption on an LCD screen. The system's circuitry was designed and simulated using Proteus software, and the LCD successfully displayed measurements obtained from the sensors. When the sump level surpassed the predetermined threshold, a relay was energized to initiate the motor, thereby pumping out the water. Similarly, the tank level sensor (LV800) detected water levels exceeding 80% capacity, sending a signal to the microcontroller, which, in turn, energized the relay to activate the stage motor. The LCD also displayed readings from the temperature and current sensors. Simulation results indicate that the proposed sensor-based approach effectively monitors the condition of the pumps. At the same time, the microcontroller, in conjunction with the sensors, can adequately control the pump's operation during the dewatering process in the mining pit. This research demonstrates the feasibility and effectiveness of employing sensors and a microcontroller in managing and controlling dewatering pumps. By automating the

As wind energy becomes a key player in the global transition to renewable energy, its variability presents significant challenges. Accurate wind ramp forecasting is crucial for managing such rapid fluctuations in wind power output, ensuring grid stability, and enhancing the reliability of renewable energy integration. This paper presents a short-term wind ramp forecasting model using a sequential approach: initially forecasting wind power through the integration of Variational Mode Decomposition (VMD) and the XGBoost algorithm, and subsequently detecting wind ramps using the Definition Based Sign Indicator (DSI) method. The historical wind speed and power data for Turkey was obtained from Kaggle. The dataset comprises readings from a wind turbine's SCADA system in Turkey, with measurements recorded at 10minute intervals. Variational Mode Decomposition (VMD) was applied to deconstruct and restore the historical wind power of the wind field, resulting in the formation of three training datasets. Wind power projections for the subsequent 8 hours, at 10 -minute intervals, are generated using historical wind power, wind speed, and wind direction as inputs. The DSI algorithm is employed to identify ramps. To assess the predictive capability of the proposed model, two algorithms, SVR and XGBoost, were employed for forecasting and the resulting error is minimal. The proposed model, VMD + XGBOOST is also compared without VMD to evaluate the performance. Taking mean square error (MSE), root mean square error (RMSE) mean absolute error (MAE), and symmetric mean absolute percentage error (sMAPE) as evaluation indicators, the results show that the forecasted accuracy of wind power is significantly improved after VMD processing. The performance of XGBOOST is better than SVR in the two evaluation indicators. Precision, Recall, and F1-score are calculated to evaluate the accuracy of the predicted wind ramps. © 2024 IEEE.

A novel facial emotion recognition model using segmentation VGG-19 architecture

Facial Emotion Recognition (FER) has gained popularity in recent years due to its many applications, including biometrics, detection of mental illness, understanding of human behavior, and psychological profiling. However, developing an accurate and robust FER pipeline is still challenging because multiple factors make it difficult to generalize across different emotions. The factors that challenge a promising FER pipeline include pose variation, heterogeneity of the facial structure, illumination, occlusion, low resolution, and aging factors. Many approaches were developed to overcome the above problems, such as the Histogram of Oriented Gradients (HOG) and Local Binary Pattern (LBP) histogram. However, these methods require manual feature selection. Convolutional Neural Networks (CNN) overcame this manual feature selection problem. CNN has shown great potential in FER tasks due to its unique feature extraction strategy compared to regular FER models. In this paper, we propose a novel CNN architecture by interfacing U-Net segmentation layers in-between Visual Geometry Group (VGG) layers to allow the network to emphasize more critical features from the feature map, which also controls the flow of redundant information through the VGG layers. Our model achieves state-of-the-art (SOTA) single network accuracy compared with other well-known FER models on the FER-2013 dataset. © 2023, The Author(s), under exclusive licence to Bharati Vidyapeeth's Institute of computer Applications and Management.
