Available in PDF, EPUB and Kindle. Book excerpt: Pavement surface texture is measured in a variety of ways in Virginia. Two methods commonly used are ASTM E 965, Standard Test Method for Measuring Pavement Macrotexture Depth Using a Volumetric Technique, known as the "sand patch" test, and ASTM E 2157, Standard Test Method for Measuring Pavement Macrotexture Properties Using the Circular Track (CT) Meter. In September 2005, staff from the Virginia Transportation Research Council inquired about using the Digital Surface Roughness Meter (DSRM®) to measure the surface texture of several concrete and asphalt surfaces. Measurements were taken on concrete and asphalt surfaces using the DSRM®, CT meter, and sand patch test, and the results were compared. From the data obtained, there appears to be a good correlation among the results of the three methods. The DSRM® and sand patch tests appear to be more accurate on surfaces that are not uniform. However, this may be because the center of the rotating arm of the CT meter may have missed particular non-uniform areas on the testing surface. The use of the DSRM® and CT meter devices also reduces the probability of human error. The sand patch test is exposed to a greater probability of human error; it is a test that cannot be performed quickly without comprising accuracy. The DSRM® is a better device to use under a time constraint.

This book was released on 2023-09-17 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the effectiveness of differential diagnosis in the degree of severity of joint pathology from a clinical, biophysical, and informational point of view. It includes the following information blocks: • Two-dimensional digital polarization microscopy of polycrystalline films of synovial fluid and determination of the coordinate distributions of the orientation and phase parameters of the microscopic image from a set of parameters of the Stokes vector. • Mueller-matrix mapping of polycrystalline films of synovial fluid and determination of a set of coordinate distributions (Mueller-matrix images (MMI)) of azimuthal-invariant elements that characterize manifestations of optical activity and linear birefringence. • Development of algorithms for polarization reproduction of distributions of linear and circular birefringence of polycrystalline films of synovial fluid. • Identification of digital statistical, correlation and wavelet criteria of polarization and Mueller-matrix differential diagnosis of the degree of severity of joint pathology. • Determination of maps of laser-induced fluorescence of synovial fluid polycrystalline films. • Identification of statistical and correlational criteria for fluorescent differential diagnosis of the degree of severity of joint pathology. • Operational characteristics of the power of the methods of azimuth-invariant polarization, Mueller-matrix and laser autofluorescence microscopy of polycrystalline films of synovial fluid.

Available in PDF, EPUB and Kindle. Book excerpt: A recent study in Australia has shown that there is a relation between low pavement macrotexture and crash incidences on highways. However, literature documents no such research in the United States. This study focuses on evaluating the role of pavement macrotexture in crashes on selected roads in the state of North Carolina (NC). Pavement macrotexture refers to variations in the road surface in the range 0.02" (0.5 mm) to approximately 2" (50 mm). Laser profilometer data obtained from the NC Department of Transportation (NCDOT) is processed to calculate estimated pavement macrotexture at one-sixteenth of a mile interval according to the ASTM standards. Crash data collected over the same lengths of the corridors were integrated with the calculated pavement macrotexture. Scatter plots, bivariate analysis and multivariate analysis showed that a strong relationship exists between pavement macrotexture and crash incidences on NC roads. Analyses and evaluation indicate that crashes decrease with increase in pavement macrotexture on NC roads. Pavement macrotexture greater than or equal to 0.06" (but typically less than 0.12") would be most appropriate to provide safe and efficient transportation to road users.

This book was released on 2024-01-03 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents experimental investigations and digital image processing, highlighting the interaction of polarized radiation with phase-inhomogeneous and optically anisotropic biological layers. The promising and efficient use of vector-parametric description of the formation of polarization-inhomogeneous object fields is noted. Applications of a set of Mueller-matrix polarimetry methods are highlighted. The book includes- structural and logical scheme of multi-parameter (singular, interference and layer-by-layer Stokes-polarimetric), polarization-correlation study of the structure of distributions of the number of singularities, maps of local contrast of interference distributions and layer-by-layer maps of microscopic polarization azimuth and ellipticity; determination of relationships between changes in the magnitude of statistical parameters characterizing polarization-correlation distributions and pathology of prostate tumors.
