A Low Complexity High Speed Architecture Design Methodology For Reduced 3-Lead to 12-Lead ECG Signal Reconstruction Targeting Remote Health Care

Cardiovascular diseases is one of the prime causes of human corporeality and mobidity in society . In order to abate this researchers had paid heed in the field of detection and pre- vention in both hospital-based and remotely accessed environments . Advancements in wireless technology and tale-monitoring can be used to provide the accessibility of state-of -the-art(Sot A) facilities to patients in remote and rural areas. However, bandwidth and storage limitations and data transmission time are major challenges in wireless transmission . Though cardiologists are habituated to standard 12-lead (S12) system because of its decade old usage and widespread acceptability, however generally, for such remote healthcare environments a reduced lead(RL)ECG is suitable for aforementioned reasons , which however , may not be clinically acceptable for diagnosis . Several efficient algorithms for reconstruction of RL to SotA 12 lead have been proposed. The overall Cardio Vascular Disease detection system can be characterized to 6 different sections namely Data Acquisition , Preprocessing , Data Transmission, Coefficient Generation, Signal Reconstruction and Display on Monitor. The thesis work includes a low complexity and high speed architecture design ( for the preprocess- sing section) and its implementation on FPGA and ASIC platform which intern can be used for the accurate reconstruction of 3 lead to 12 lead ECG signal reconstruction

A comparison of processing techniques for producing prototype injection moulding inserts.

This project involves the investigation of processing techniques for producing low-cost moulding inserts used in the particulate injection moulding (PIM) process. Prototype moulds were made from both additive and subtractive processes as well as a combination of the two. The general motivation for this was to reduce the entry cost of users when considering PIM. PIM cavity inserts were first made by conventional machining from a polymer block using the pocket NC desktop mill. PIM cavity inserts were also made by fused filament deposition modelling using the Tiertime UP plus 3D printer. The injection moulding trials manifested in surface finish and part removal defects. The feedstock was a titanium metal blend which is brittle in comparison to commodity polymers. That in combination with the mesoscale features, small cross-sections and complex geometries were considered the main problems. For both processing methods, fixes were identified and made to test the theory. These consisted of a blended approach that saw a combination of both the additive and subtractive processes being used. The parts produced from the three processing methods are investigated and their respective merits and issues are discussed
