The main objective of this project is to design and implement a Fast Fourier Transform (FFT) IP core. Due to its ability to provide accurate frequency domain analysis of time domain signals, the FFT technique is indispensable in many applications related to digital signalprocessing. The implementation is based on the radix-2 method, whose lower computational complexity and hardware resource efficiency make it a good fit for FPGA platforms. With its robust FPGA and ARM CortexA53 processors, the ZCU104 board provides an adaptable environment for creating unique IP cores and incorporating them into more complex *** objective of this project is to use the Zynq SoC’s hardware acceleration capabilities to improve the FFT core for speed and resource consumption. The ZCU104 board is used to test and validate the built IP core, proving its usefulness for real-time signalprocessing applications. As compared to software-based FFT implementations, the results demonstrate a notable boost in performance, underscoring the potential of FPGA based solutions in high performance computing jobs.

We propose the first digital ultra-low-bit precision implementation of a Linear Embedded Beamforming (LE-BF) system, which transforms high-dimensional input signals into low-dimensional outputs. The use of quantization compensation in this operation ensures beamforming performance is preserved. The system then processes the low-dimensional outputs to generate the final output with lower power consumption. The paper presents two different implementations of LE-BF systems: 1) An FPGA-based 2-bit LE-BF system configured with 64 inputs and 1 output, achieving a $12.4 \times$ decrease in design component utilization and a $11.2 \times$ decrease in power consumption compared to corresponding traditional True-Time-Delay digital beamforming (TTD-DBF) designs. 2) An ASIC-based (TSMC 28nm) 2-bit LE-BF configured with 256 inputs and 1 output, exhibiting a $18.7 \times$ greater efficiency in both design area and power consumption compared to corresponding TTDDBF designs. The ASIC-based system is capable of supporting a 1 GHz instantaneous bandwidth.

The fast growth of the 'Internet of Things' (IoT) has impacted on several sectors, including fuel management. This paper describes the design, fabrication, and implementation of an IoT-based smart fuel monitoring system to improve the effectiveness of using fuel resources while minimizing losses and optimizing processes. A Rasp berry Pi controller with various sensors tracks essential parameters such as fuel level, temperature, pressure, pH, and gas levels. The system also provides for processing and presenting the collected data through a mobile application and a website, making it possible to manage the system further from the users via remote control. The system was tested using two fuel types, Benzene and Diesel, and it was effective in fuel parameters management. Results established that the pressure of Benzene was reasonably constant, and it was about 14.8 psi after reaching equilibrium. In contrast, the pressure returned to 14.7 psi value for Diesel, which was its initial value. The temperature readings were constant throughout the experiment, with the benzene temperature being higher than Diesel. The system also differentiated between pH levels, keeping Benzene at 6.9 while Diesel at around 7. These results prove the capabilities and efficiency of this system in anomaly detection, fuel adulteration, and fuel theft prevention, thus solving modern solutions in fuel management.

A 3D glass packaging solution has been developed as a power brick module for high-efficiency, high-power density 48 V DC-DC converters, which are essential for applications such as data centers, telecommunications, and autonomous driving. As compute power demands increase, transitioning from 12 V to 48 V architectures significantly reduces power distribution losses. By leveraging 3D heterogeneous integration, the presented design features vertical stacking of passive and active components, including an isolated supply, a digital signal isolator and a GaN half-bridge, within a modular power brick. The top placement allows for various cooling options for the thermal management, as the half-bridge is designed for high currents up to 35 A. The package employs three precisely structured glass substrates, utilizing selective laser-induced etching and laser ablation to form complex glass geometries and conductive paths. The electrical functionality of the circuit is validated in an 48 V application with an isolated ground. With the 3D integration in a glass-based package, a footprint reduction of 56% compared to a traditional planar PCB implementation is achieved. These advancements underscore the potential of glass substrates for enhancing power density and facilitating the integration of glass packages in future 48 V applications.

The DUNE experiment studies neutrinos, fundamental particles that interact weakly with matter. This work describes the development of a subsystem for signal digitization on the DAPHNE card test bench, a critical component in the experiment's data acquisition. HDL designs were implemented on an FPGA, and pulses were generated using an ESP32 microcontroller, which were then converted to analog signals through its DAC. The evaluation was performed using the Analog Discovery 2 device. The results confirmed the correct implementation of the HDL designs, based on predefined data and difference equations. The difference equation-based model demonstrated greater dynamic processing capability, albeit with higher resource consumption, whereas the predefined data design proved more resource-efficient. This development enhances the evaluation of the DAPHNE board, increasing its reliability and adaptability within the context of the DUNE experiment.
