Terrain modelling in surveying and civil engineering☆

AbstractThis paper is a review of the application of terrain modelling to surveying and civil engineering. The first section considers the theoretical background to the subject and two distinct approaches are identified based on the use of either grid or randomly located height data. The relative merits of each are discussed and the most frequently used algorithms for interpolation and contouring are examined. This is followed by a review of the characteristics of a selected number of terrain modelling and contouring packages. Five distinct groups of packages are identified. Finally, a review of applications is presented together with some views on the future trends in this field.

Measurement of chemical reaction rates following electron transfer. An empirical approach using ring-disk electrodes

SummaryAn empirical calibration procedure for the rotatedring-disk electrode has been developed, following a suggestion by Albery and Bruckenstein. This allows the precise measurement of the rates of simple EC processes (Electron transfer followed by Chemical reaction) of moderate rates. A rather wide-gap carbon-paste ring-disk electrode, which is not too difficult to construct, is described.
