70 114. Sampling Scope Acquisition System This project develops a high-bandwidth sampling oscilloscope capable of reconstructing repetitive waveforms in the GHz range. The system employs precise time measurement components, comparators, and a digital-to-analogue converter to sample signals by triggering start and stop events based on programmable voltage thresholds. Amicrocontroller processes the sampled data and reconstructs the waveform for analysis. The design prioritises high resolution and low jitter, while ensuring cost- effectiveness and scalability. This innovative solution addresses the limitations of traditional oscilloscopes, offering advanced signal analysis capabilities for applications in telecommunications, radar systems, and high-speed electronics testing.

Emissivity plays a critical role in accurate temperature monitoring for industrial processes, particularly in materials with dynamic phase transitions such as NiTi. The study utilises a calibrated thermal stage and an infrared (IR) data acquisition system to collect precise emissivity measurements. LabVIEWsoftware processes the IR radiation from the heated samples, enabling real-time voltage-to-temperature data conversion. The findings aim to develop accurate calibration curves for NiTi alloys, contributing to improved temperature monitoring systems and advancing the understanding of emissivity variations in shape memory alloys.

The project focuses on designing and constructing a high-capacity compressive hydraulic testing rig capable of testing steel access covers up to the B class of the BS EN 124 standard. Additionally, the project includes performing finite element analyses on both the rig and the covers to optimise the design and suggest improvements to the manufacturer of the steel access covers. The analyses investigate locations of high stresses and strains, which are then minimised in the design. The project document also provides a detailed description of the British standard for load capacity testing of manhole covers and gully tops, and explains how this standard informs the design of testingmachinery.
