Analysis of technological change and relief representation in U.S.G.S. topographic maps
… Measures of closed contour lines recorded the angularity of the line, the length of the line, the area within the contour, the shape of the feature and spatial relationships between contour pairs. The analysis attempts to relate errors to these geometric components of contour lines and to …

A comparison of temper characteristics between Virgin Anasazi black-on-gray bowl rim sherds and plain gray jar rim sherds from Yama-2 and Yama-3
… temper sorting; temper percentage; temper angularity; and temper size. Black-on-gray bowl rim sherds mostly contain quartz and olivine temper and plain gray jar rim sherds contain more mixed sand, sherd and quartz/feldspar temper. Dates of A.D. 1050-1100 (mid-Pueblo II) with mixing from …

The coloured cube test and the coloured mental rotation test: two new measures of spatial ability and mental rotation
… (CMRT), investigated differences in set-size, angularity, and axis of rotation of coloured cube aggregates in 4- to 11-year-old children (N=80). Several higher-order interactions all involved set-size and showed that 4-cube aggregates were the most economical and best 3D object for children’s …

Quantification of Morphological Characteristics of Aggregates at Multiple Scales
… characteristics, including shape factors, angularity and texture. These morphological characteristics influence the aggregate's mutual interactions and strengths of bonds between the aggregates and the binder. The interactions between aggregates and bond strengths between the aggregate and …

Development and application of an integrated aerodynamic and thermodynamic testing system for cars
… force and downforce on cars. However, a little angularity of a device, such as the side front canards, to the flow direction, can significantly alter its function. The flow visualization test showed that the local flow direction strongly depends on the local geometry. The temperature study …

‘Static dynamic’: An urban Outward Bound centre for youth
… contrast in scale, interiority and exteriority, angularity to rectilinearity, orthogonal to curvilinear, light and dark, and a range of textures from smooth to rough. The design also explores how socially dynamic as well as private and calmer static spatial experiences can add variation and …

Development of Three-Dimensional Image Analysis Techniques to Determine Shape and Size Properties of Coarse Aggregate
… sieve size can be computed. In addition, a new angularity index based on image analysis principles has been developed. This index is calibrated in a manner that allows for a clear distinction to be made between crushed stone and rounded gravel particles. The main focus of this doctoral study was …
