Mr. Nicholas Caccese is a Technical Associate at CBE Consultants, Inc. Mr. Caccese is gaining experience applying biomechanics to a variety of real-world problems, including: automotive collisions; falls from various heights and in various orientations; impacts from falling objects; injuries resulting from the misuse of a variety of devices; and amusement ride verification. After completing an M.S. and B.S. program in Biomedical Engineering at Temple University, Mr. Caccese began his consulting career in 2019. Mr. Caccese utilizes his knowledge to assist in investigating and assessing the forces, accelerations, and motions experienced by the human body. Mr. Caccese is also developing the ability to review medical records for the purpose of assisting in the evaluation of the extent, distribution, and severity of injuries and the past medical history as it relates to the biomechanical analysis and claims, while assessing the biomechanical forces that could lead to the causation of any claimed injuries. He also has experience reviewing a variety of different imaging modalities, including Fourier Transform Infrared Imaging Spectroscopy (FTIR-IS) for evaluation of various biomedical samples and constructs, with an educational background in CT and MRI imaging. Mr. Caccese’s research interests include the anthropometry of device usage, computational modeling of different bodily systems, and statistical evaluation of varying data sets.

As a consultant, Mr. Caccese applies his knowledge to assist with the analyses of injury causations and accident reconstructions for a variety of projects. He assesses whether motions, accelerations, and loads can cause injury, and his experience includes contributing to analyses and reconstructions of motor vehicle crashes; sports, and occupational injuries; and falls. He also contributes to biomechanical analyses of incidents involving consumer devices, including rolling knee walkers and hydraulic lifts, and amusement devices, including roller-coasters and water rides. He has contributed to the evaluation of biomechanical issues and injury potential associated with alternate scenarios, such as changes in design or safety equipment.

Prior to his consulting career, Mr. Caccese was employed by the research labs of Temple University’s Bioengineering Department. His areas of research included: developing modules for an image tracking system to allow for computer assisted control of experiments into mechanics of animal locomotion response; culture, verification, and validation of multiple different cell lines; and design of devices to automate laboratory protocols for a research environment. In addition to his research, he operated as the assistant lab manager where he coordinated certifications, trainings, and logistical concerns for approximately 30 members across four different research groups and completed maintenance of shared laboratory equipment. He also was a founding member of the Temple University Biomedical Engineering Society (BMES) student chapter and acted as the secretary and vice president over the course of his undergraduate studies.

Abstract

Project Based Learning (PBL) has been shown to be effective in bridging the gap between theoretical and practical engineering education. This transition is especially useful when attempting to convey abstract engineering topics, such as intrinsic properties of materials and the response of complex systems. Engineering dynamics has been specifically shown to be enhanced by using a PBL approach as visualizing the time-response of a system has, anecdotally, been difficult for students to learn. To enhance student understanding of this topic, we are using a real-world case study of potential head injury due to a falling piece of plaster in an undergraduate biomechanics course to illustrate fundamentals of impacts and fracture mechanics. To capture this effect, we are presenting a Jupyter-based analytic model to assist students in the evaluation of the response of frangible materials to impact and how the energy and momentum that are transferred over the duration of the impact varies as a result of differing initial problem conditions. The use of a computer simulation of a complex dynamic system will enable students to “visualize” the effects of parametric changes and improve student learning.

The students in the class are familiar with analyzing open-ended problems that require the teams to apply fundamental knowledge in a PBL setting. This project covers an injury case of falling plaster on a seated individual. The students will be presented with the project as they are learning impact mechanics to do an on-paper analysis and report. The project will be presented a second time with the students being able to use a Jupyter-based simulation of the incident as part of their analysis toolkit. Comparisons between the two reports will be made to evaluate the approaches to the injury analyses by the student teams. The report format contains a reflection section, where the teams assess their learning and approach to the presented problem. In addition, the students will be assessed to gauge their understanding of the topics presented in the PBL by using pre- and post-module quiz questions and reflective statements from PBL reports to gauge student learning and student opinions about using real-time visual aid in their comprehension of impact mechanics.
