Impact of Color Space and Color Resolution on Vehicle Recognition Models

Publikováno v: Journal of Imaging, Vol 10, Iss 7, p 155 (2024)

In this study, we analyze both linear and nonlinear color mappings by training on versions of a curated dataset collected in a controlled campus environment. We experiment with color space and color resolution to assess model performance in vehicle r

Autor: Roger W. Geiss, Patsy H. Lill, Peter G. Anderson, Regina Kreisle, Kristopher N. Jones, John H. Holliman

Publikováno v: Archives of Pathology & Laboratory Medicine. 126:346-350

Background.—The Group for Research in Pathology Education (GRIPE) is an organization of pathology educators whose purpose is to promote and facilitate excellence in pathology education. One important function of GRIPE is the maintenance of image an

Pathology

Autor: John H. Holliman

These notes were developed as a synopsis of general and systemic pathology in order to present to those students who are preparing for national examinations a relatively concise review of the discipline. These notes are not intended to replace the ma

Self‐gravitational Hydrodynamics with Three‐dimensional Adaptive Mesh Refinement: Methodology and Applications to Molecular Cloud Collapse and Fragmentation

Autor: Louis H. Howell, Richard I. Klein, D. Tod Woods, John H. Holliman, Jeffrey A. Greenough, Christopher F. McKee, J. Kelly Truelove

Publikováno v: The Astrophysical Journal. 495:821-852

We describe a new code for numerical solution of three-dimensional self-gravitational hydrodynamics problems. This code utilizes the technique of local adaptive mesh refinement (AMR), employing multiple grids at multiple levels of resolution and auto

The Jeans Condition: A New Constraint on Spatial Resolution in Simulations of Isothermal Self-gravitational Hydrodynamics

Autor: Jeffrey A. Greenough, Christopher F. McKee, Louis H. Howell, Richard I. Klein, J. Kelly Truelove, John H. Holliman

Publikováno v: The Astrophysical Journal. 489:L179-L183

We demonstrate with a new three-dimensional adaptive mesh refinement code that perturbations arising from discretization of the equations of self-gravitational hydrodynamics can grow into fragments in multiple-grid simulations, a process we term "art

Multi--Pressure Polytropes as Models for the Structure and Stability of Molecular Clouds. I. Theory

Autor: Christopher F. McKee, John H. Holliman

Molecular clouds are supported by thermal pressure, magnetic pressure, and turbulent pressure. Each of these can be modeled with a polytropic equation of state, so that overall the total pressure is the sum of the individual components. We model the
