DCU Expo 2024 - Final Year Projects

35 15. Ultrasonic Heat Pump This project assists in the research and development of an ultrasonic heat pump in collaboration with Exergyn. Exergyn specialises in solid-state heat pumps. Ultrasound is when mechanical waves reach a frequency above 18–20 kHz, which is beyond the limit of human hearing. Ultrasound is known to be an effective method of enhancing convective heat transfer due to its unique effects inside the fluid under its irradiation, such as acoustic cavitation and acoustic streaming. This heat pump is developed using a small ultrasonic transducer that operates at 40 kHz, a rubber silicone heating pad, thermocouples, and other measurement devices to be used for a data acquisition program that is developed in LabVIEW.

Two fixation devices were analysed; the dynamic compression plate and the fastenerod. Parameters of the two fixation devices, such as the number and placement of the screws, the distance between the device and the bone’s surface, and the fracture gap length, were varied during the simulations in order to record their effects on the interfragmentary strain at the fracture site. These effects were analysed to determine which of the factors had the most significant influence on the bones natural ability to heal.

This project incorporates static and dynamic signature verification. Static verification, otherwise known as offline verification, is based on the idea of being able to verify a signature through images and analysing characteristics that can be used to distinguish between a forged signature and an authentic signature. Dynamic signature verification is based on the idea of being able to identify foreign signatures in real-time and comparing them to the known signatures in the database. The project is built on a web app and is deployed as an application.
