In this paper, we demonstrated a highly sensitive microwave-based resonator sensor capable of detecting variations in an aqueous medium of up to 0.94 mg/dL. In the presented device, the intrinsic resonant response (resonant amplitude, resonant frequency, and quality factor) is capacitively perturbed in reaction to the sample presence. To achieve higher sensitivity, the sample under testing generally is placed on the resonator surface, where the electric field is highly concentrated at the operating frequency. Thus, demonstrating excellent results in terms of sensitivity and reproducibility.

Thanks to the Internet of Things (IoT) revolution and advancements in embedded systems, the incorporation of an extensive array of sensors and computational resources into vehicles has become a reality, significantly enhancing their capabilities to produce relevant data. This has opened up new opportunities for acquiring and processing vehicular data in various areas, supporting new applications such as vehicular monitoring to the use of information for artificial intelligence for improved decision-making tasks. However, although the benefits are promising, there is a current challenge when providing flexible and standardized procedures to capture, process, and store this information for further analysis. In this context, this article proposes an framework to support the the handling of vehicular data, including data processing by a server and storage in a cloud database. This framework was validated through a real-world case study, analyzing the collected sensor data. The results indicated the feasibility of the proposal, contributing to the availability of vehicular data analysis in a way that is distinct from proposals in the literature. Additionally, this framework offers another significant contribution, related to the use of an appropriate database for time series, enabling scalability and high availability.

Deeply implanted bioelectronic devices that selectively record and stimulate peripheral nerves have the potential to revolutionize healthcare by delivering on-demand, personalized therapy. A key barrier to this goal is the lack of a miniaturized, robust, and energy-efficient wireless link capable of transmitting data from multiple sensing channels. To address this issue, we present a wireless galvanic impulse link that uses two 500μm diameter planar electrodes on the outside of a nerve cuff to transmit data to a wearable receiver on the skin’s surface at rates greater than 1Mbps. To achieve an energy-efficient, high data rate link, our protocol encodes information in the timing of narrow biphasic pulses that is reconstructed by the wearable receiver. We use a combination of modeling and in vivo and in vitro experimentation to demonstrate the viability of the link. We demonstrate losses lower than 60dB even with significant, 50mm lateral misalignment, ensuring a sufficient signal-to-noise ratio for robust operation. Using a custom, flexible nerve cuff, we demonstrate data transmission in a 14mm-thick rodent animal model and in a 42mm-thick heterogeneous human tissue phantom.

Future data transmission requirements will be greater, speedier, and more extensive. This is provided by the 6G communication network, which employs frequencies of 100 GHz and above (terahertz). So that all devices can be effectively connected and controlled by humans. However, high frequencies can be attenuated by the atmosphere. The weakening of the terahertz signal received by the receiver system due to attenuation. This paper examines the impact of rain attenuation on the performance of 6G systems using the parameters of free space loss, precipitation, and acceptability. Therefore, a computer simulation approach was conducted to obtain the performance. In this paper, 100 GHz and 300 GHz frequencies were used in LOS conditions, respectively. In addition, two different power transmits: 20 dBm and 24 dBm, and a distance between the base station (BS) and the user equipment (UE) extending from 100 to 600 meters are considered as parameters. The results indicate that the free space loss (FSL) is increase with increasing distance as well as the frequency used increases. As distance increases, the rain attenuation with a high frequency is increased. The received power for each power transmission remains within the acceptable range of the 6G communication network.

A passive harmonic filter is a type of filter designed to mitigate the adverse impacts of harmonics by effectively attenuating multiple harmonic frequencies or a broad frequency spectrum. The objective of implementing a double-tuned damped passive filter is to improve the overall performance of the system with respect to electric power quality. This paper is to develop a simulation model for a harmonic step filter control system that meets the requirements of household electricity. This system is designed to regulate various parameters such as current, voltage, frequency, power factor, active power, and reactive power of the electrical load. The ultimate goal is to enhance control and improve the quality of electricity consumption. household. The proposed research methodology involves the development of a 6-step control simulation model utilizing Matlab Simulink. Subsequently, a control design model will be implemented using the ESP 32 microcontroller, PZEM004t sensor, and PZCT-02CT sensor. Additionally, a relay module will be employed to activate the damped double-tuned filter. This relay module comprises 6 steps, each equipped with a filter designed to respond gradually based on the power quality value. The results show that the Total Harmonic Distortion Voltage (THDv) is at 7.07%, the Total Harmonic Distortion Current (THDi) is at 47.55%, and a power factor of 0.68. By implementing the proposed damped double-tuned filter, a reduction in harmonic values can be achieved. Specifically, the THDv can be reduced to 1.1%, the THDi can be reduced to 0.65%, and the power factor can be improved to 0.77.

The occurrence of multi-switching on an isolated gate bipolar transistor (IGBT) function can cause significant power dissipation and disrupt the power network. To overcome this problem, this paper designs a hysteresis amplifier model to reduce multi-switching in IGBTs. This software is used to simulate and analyze the performance of the hysteresis model amplifier. The hysteresis amplifier design is used to induce a hysteresis effect on the IGBT control signal. This effect produces an output frequency of 50 Hz with a 50% duty cycle. The working mechanism of this design includes the formation of a hysteresis window on the IGBT control signal, +2.00 V to +2.52 V. If the design result of the control signal is at least +2.50 V to +2.48 V, the IGBT enters the active state when Vout1 reaches +3.51 V. The design results in the control signal reaching a maximum value of +2.50 V to +2.51 V. The IGBT transitions to the active state when the voltage at Vout2 reaches a threshold of +3.51 V. The automatic implementation of the hysteresis window effectively reduces the occurrence of multi-switching by ensuring that a switch event occurs when the control signal is within the specified hysteresis window range. The current transformer detects changes in current through the variable resistor when Vin +2.00V to Vin +2.52 V. By understanding the characteristics and implementation of the model, it is possible to formulate intelligent control strategies aimed at increasing the efficiency and stability of system power through the use of IGBT.

Fantasy Sports has a current market size of ${\$}$27B and is expected to grow more than ${\$}$84B in less than a decade. The intent is to create virtual teams that somehow reflect what would happen if the constituent players actually played in a team. Using individual player and team statistics, models can be trained to predict an outcome. But fans are left wanting more. To achieve a more realistic outcome, aspects of what makes live teams win need to be included: (1) transforming player statistics to reflect their relative importance with respect to a player position; (2) team chemistry (TC). In this work, we show a novel characterization of relative position statistics and a new description of TC. Drawn from the NBA’s API, we form a data set to determine whether a fantasy team makes the playoffs using almost two dozen features, including TC. Various Machine Learning models are trained on this data and the best-performing model is offered to the users through a web service. Users can not only inspect fantasy teams and their TC but can also simulate their match-ups with existing 2023 NBA teams and utilize performance visualizations to help improve their team creation process. Our web service can be accessed at https://***/fantasyleague/, and the source code can be found at https://***/gany-15/nbafan.
