Aggregates constitute major part of the pavement structure. The engineering properties of the aggregates, as well as its shape (i.e. form and angularity) and texture, substantially affect the overall performance of the pavement (Kuo and Freeman 1998, Maerz 2004). A number of researchers reported that form and surface texture of aggregates have significant effect on the mechanical property of th...

Humans have a preference for curved over angular shapes, an effect noted by artists as well as scientists. It may be that people like smooth curves or that people dislike angles, or both. We investigated this phenomenon in four experiments. Using abstract shapes differing in type of contour (angular vs. curved) and complexity, Experiment 1 confirmed a preference for curvature not linked to perc...

Genetic correlations between first calving interval (CI) and linear type traits in South African Holstein and Jersey cattle were estimated to assess the possibility of using type information as selection criteria for CI. All linear type traits routinely evaluated under the National Genetic Evaluation Programme (18 for Jersey and 17 for Holstein) were considered. Data were obtained from the Nati...

The morphology of coarse aggregate has a significant impact on the road performance asphalt mixtures and characterization studies, but many studies were based two-dimensional aggregate, which failed to consider morphological characteristics in holistic manner. In order quantitatively analyze shape, angularity, texture roadway aggregates, rapid accurate multiparameter method 3D is explored this ...

Linear type scoring is key component in decision making process the herd, as it focusses on selection of animals with higher productive potential based their body conformation/linear traits. The present study was carried out 150 lactating Sahiwal cattle first to fifth parity. Measurements linear traits were recorded 1 h before evening milking at three different stages lactation. average score p...

Abstract Roundness/angularity is a vital shape descriptor that significantly impacts the mechanical response of granular materials and closely associated with many geotechnical problems, such as liquefaction, slope stability, bearing capacity. In this study, series biaxial shearing tests are conducted on dual-size aluminum circular hexagonal rod material. A novel image analysis technique used t...

Sixty Duroc pigs, representing offspring of three lines from the fifth generation of divergent selection for leg weakness, were examined to determine correlated responses in joint angularity. The lines were low, control, and high, with the latter having superior front leg structure. At approximately 100 kg, 10 pigs of each sex and line were scored for front and rear leg structure and movement. ...
