Wax distribution quantification using digital image analysis techniques
A wax distribution quantification procedure using digital image analysis and fluorescence microscopy techniques was developed. The procedure was evaluated by investigating the effect that variable application rates have on wax distribution. The effect of emulsion type and application on |B …

Digital image analysis of HL-60 proliferation and granulocytic differentiation.
Biochemical and computer-assisted digital image analysis techniques were used to study the proliferation and granulocytic differentiation of HL-60 leukemia cells which were induced to differentiate by retinoic acid (RA). HL-60 cells were synchronized by density arrest (DA), double thymidine block …

Determining the Air Void Parameters of Concrete Using Digital Image Analysis of Polarized Light Micrographs
… evaluating concrete air void parameters using an image analysis method. A polishing procedure along with a differential interference contrast microscope are used to obtain high contrast images of material constituents, which provide raw data for the image analysis method. Because of the high …

Single Walled Carbon Nanohorns as Photothermal Absorbers, and Incorporation of Spatial Digital Image Analysis into Cancer Diagnostics and Therapy
… distributed treatment, traditional experimental analysis methods used to assess photothermal therapy have either lacked spatial assessment such as is the case with standard viability assays of cell monolayers, or they only provide macroscopic treatment information, such as the measurement of the …

Use of digital image analysis to identify <i>Rhizoctonia solani</i> and <i>Rhizoctonia zeae</i> resistance in <i>Festuca arundinacea</i> plant introductions
… of this study were to develop an objective digital image analysis (DIA) method for evaluating disease and to use DIA to screen tall fescue plant introductions (PIs) for resistance to <i>R. solani</i> and <i>R. zeae</i>. There was a strong correlation (r<sup>2</sup> = 0.97) between actual …

The Heritability of Seedling Stage Drought Resistance in Rape and Its Relationship to Seedling Root Morphology
… were 43% and 63%, respectively. Comparisons of digital image analysis measurements of root length and measurements of root dry mass suggest that rooting depth and extent affect seedling stage drought resistance.

CHARACTERIZATION OF IMMUNE RESPONSE IN EXPERIMENTAL MOUSE MODELS
… Study III – Comparison between two methods of digital image analysis (hot-spot fields vs whole-slide) for the assessment of immune cell infiltrations in a murine caerulein-induced acute pancreatitis model. Study IV – Tumor immune system interaction in a murine model of orthotopic pleural …

Expression of the P-glycoprotein Homologue1 on food vacuoles isolated from Chloroquine-sensitive and resistant Plasmodium falciparum strains
… levels on food vacuoles were measured with digital image analysis. The chloroquine-sensitive strains 307 and D10 and the chloroquine-resistant strains K1 and RSA 11 expressed equal amounts of Pgh1. The chloroquine-resistant FAC8 strain expressed at least three times more vacuolar Pgh1. No …

Investigations of Ethylene and Ethylene Inhibition, Ball Lie, and Synthetic Turf Color
… color retention qualities of synthetic turf by digital image analysis. While color change was noticed, quantification of color change was not consistently measured.</p>

Two novel techniques to study multiple bolted wood connection behavior
… novel techniques, instrumented shear bolts and digital image correlation, were evaluated for studying multiple-bolted wood connection behavior. The instrumented shear bolts output an electronic signal proportional to the shear forces transmitted through the bolt in a double-shear connection …

Bubble Dynamics and Dense Phase Composition in 2-D Binary Gas-Solid Fluidized Bed
… some fundamental understanding of this system. Digital image analysis (DIA) was employed to measure bubble diameter, bubble rise velocity, bed expansion and particle composition distribution. Magnetite and sand particles as pure and binary mixtures were used in the fluidized bed. Bubble diameter …

Investigating Spring Dead Spot Management via Aerial Mapping and Precision-Guided Inputs
… maps were compared for spatial accuracy to Digital Orthophoto Quarter Quadrangle (DOQQ), ground-validated differential GPS coordinates, and to 2017 SDS incidence maps, with average deviations of 1.3 m, 1.6 m, and 0.1 m, respectively. Digital Image Analysis (DIA) of aerial maps was compared …

The behaviour and wing morphology of the meadow brown butterfly (Maniola jurtina L.) in Britain : the influence of weather and location
… and wing size and darkness determined using digital image analysis. Warm-up rates of butterflies of known wing morphology were determined under laboratory conditions. In the north, conditions are cooler, cloudier and windier; habitat is more restricted and butterflies were found to be at …

VRCC-3D+: Qualitative spatial and temporal reasoning in 3 dimensions
… visual programming language semantics, and digital image analysis. Systems for spatial reasoning over a set of objects have evolved in both expressive power and complexity, but implementations or usages of these systems are not common. This is partially due to the computational complexity of …

The mechanisms underlying convergent evolution in the plumage patterns of birds
… I quantified their barred patterns using digital image analysis and found that parasitism can explain convergent evolution in the patterns of parasitic cuckoos and raptors. Patterns may have evolved due to ecological selection. Examining the patterns of 80% of all avian species worldwide, …

New Technologies for Evaluating Putting Green Surface Characteristics
… well as (ii) standard research methodology using digital image analysis (DIA). The modified TDR 300 produced significant (P < 0.0001) linear prediction equations for 1.2 and 2.5 cm depths. The DGCI from the GreenIndex+ Turf app lacked the consistency of standardized DIA. Based on these results, …
