Development Of A Self-Powered Weigh-In-Motion System, Athanassios Papagiannakis, Athanassios Papagiannakis, Samer Dessouky, Sara Ahmed, Reza Khalili, Gopal Vishwakarma

Data

This report describes the development of a novel weigh-in-motion (WIM) system that utilizes piezoelectric elements for sensing load and powering an ultra-low power microcontroller unit (MCU) that serves as its data acquisition system. A system of 4 piezoelectric (PZT) stacks serves as the energy harvester, while load sensing is done via a set of 4 PZT elements connected in parallel. Two alternative MCUs were considered, with various data handling capabilities and power consumption requirements. These MCUs have very short “wake-up” times allowing vehicle sensing without the need for inductive loops commonly used in conventional WIM systems. Special electric circuits were …

Development Of A Self-Powered Structural Health Monitoring System For Transportation Infrastructure, Aydin Karsilaya, Samer Dessouky, Athanassios Papagiannakis

Data

Corresponding data set for Tran-SET Project No. 17PTAM03. Abstract of the final report is stated below for reference:

"Roadways and bridges play an important role in the economic and social health of society by connecting commerce and people. Economic growth and population expansion pose considerable burden on the aging infrastructure (i.e., pavements and bridges). There is a pressing need to develop structural health monitoring (SHM) technologies capable of collecting infrastructure utilization data. Doing so inexpensively with self-powered systems will revolutionize infrastructure monitoring technology, and will improve decision making enabling roadway and bridge preservation. In this study, a self-powered battery-less structural …

Towards Artificial Proprioception In The Mandibular Full Arch Fixed Implant Prosthesis, Md Abu Hasan

Mechanical and Aerospace Engineering Dissertations

Full arch fixed implant prosthesis has been one of the most effective treatment modalities for fully edentulous patients over the last few decades. However, due to lack of proprioception occlusal overload is experienced by the prosthesis and its components causing major biomechanical complications such as screw/abutment fracture, framework fracture, and bone loss. The currently available approaches for the overload management rely on external appliances such as an occlusal splint or bite guard and result in occlusal discomfort and high patient dissatisfaction. In this research, an approach to induce artificial proprioception in the full arch fixed implant prosthesis is proposed. However, …
