    Development of 3D Bioactive Glass Bone Scaffolds for Bone Tissue Engineering
    (Office of the Vice Chancellor for Research, 2015-04-17) Justiniano, Amanda; Zhang, Jing
    The goal of this research project is to develop a three-dimensional designed bioactive glass bone scaffold that can positively assist with bone regeneration. Current development and research emphasized on bone tissue engineering, is a big contribution towards many fields in science and engineering. In this project, a new bone scaffold that will help further studies in bone tissue engineering and bone regeneration will be developed using state-of-the art 3Dprinting technique. The bioglass material that will be used in this project is considered to be a promising material for bone scaffolds due to their ability to assist with tissue regeneration. The significance of this project is to provide a new methodical approach in order to precisely design the microstructure and thus build bone scaffolds that can effectively stimulate bone regeneration. The methods used in this research include the incorporation of computer-assisted design in order to build a model scaffold that will be 3d printed and evaluated.

    Study and Analysis 100-car Naturalistic Driving Data
    (Office of the Vice Chancellor for Research, 2013-04-05) Justiniano, Amanda
    Every year, there are a large number of injuries and fatalities caused by vehicles crashes. In particular, pedestrian accidents are often fatal and have greatly impacted people’s lives. Vehicle active safety system can sense and identify potential crash events and prevent or mitigate the collision either by warming the driver or by taking appropriate control actions such as autonomous braking. To design such these kinds of systems, we need to study how accidents happen and to avoid the accident in real-life scenarios. In this research, the Transportation Active Safety Institute (TASI) has recruited 110 drivers to collect naturalist driving data for pedestrian behavior analysis. In this project, my work is first to study how automatic pedestrian detection system works and verifies the detection results. I have worked analyzing picture frames from videos and by identifying pedestrians in these picture frames. Other components that are taken into consideration are the human factors, biomechanics, data acquisition and analysis, and consumer awareness. TASI uses facilities such as car simulators, Drive Safety DS-600c, directed towards the research of the driver’s behaviors and for testing the active safety system. It is the main source for testing the system since it projects a scenario of road images that interacts with a cab of a car to provide an immersive driving experience. Upon completion of the research, there should be a successful safety system for implementing in cars that can effectively reduce vehicle crashes by alarming drivers of different dangers that might appear while driving.
