Advancements In Panoramic-Dic System For Vascular Imaging, Zhuangyu Zhang

Mechanical Engineering and Materials Science Independent Study

Digital Image Correlation (DIC) has become an important imaging technique in biomechanics, known for its non-invasive, optical assessment capabilities. However, traditional DIC systems have several limitations in biomechanical applications such as restricted observational fields and challenges to maintain the sample integrity. Advancements in the DIC technique have led to the development of panoramic-DIC (pDIC) systems. The pDIC system addresses the need for more comprehensive imaging of quasi-cylindrical samples by utilizing a sophisticated array of cameras and mirrors. It employs a concave conical mirror, transforming a conventional binocular stereo-DIC setup into an almost infinite-view system, through the use of multiple cameras …

Journal of Bioresource Management

The range grazing livestock (cattles and goats) are afflicted by a significant skin/hide issue known as warble fly larval infestation, which is caused by the larvae of Hypoderma lineatum and Hypoderma bovis species which resulted in substantial economic losses to the leather industries. The life cycle of hypodermosis is complex, involving both ecto- and endoparasitic stages. Female warble flies deposit their eggs in rows of 5-8 on individual hairs of the host, often targeting the legs but also other areas. These eggs are securely attached to the hairs and a single female fly may lay as many as 800 eggs …

Information-Rich 6d Single-Molecule Imaging Design Using Optimization, Tingting Wu

McKelvey School of Engineering Graduate Student Theses & Dissertations

When studying biochemical processes, localizing the targets alone will not paint a complete picture. We also need techniques to probe how biomolecules interact with one another, including how molecules are organized into larger structures, how they are oriented with respect to surrounding molecules, and how local chemical parameters, like pH and hydrophobicity, vary spatially and temporally. My dissertation focuses on single-molecule orientation localization microscopy (SMOLM, Chapter 1). The objective is to develop imaging techniques for measuring how molecules are oriented with respect to their surrounding molecules, namely, 3D orientation. Achieving optimal imaging performance requires careful design of both the forward …
