FUNDAMENTAL STRUCTURES FOR THE DESIGN OF MACHINE VISION SYSTEMS

Johnson J.; Simon J.C. (2001)

The chicken-and-egg problem of machine vision is that (a) abstracting objects requires images to be segmented, (b) segmentation requires greyscale statistics, (c) greyscale statistics are defined by segmented regions, and ...

FUNGAL INVOLVEMENT IN BIOWEATHERING AND BIOTRANSFORMATION OF ROCKS AND MINERALS

Burford E.P.; Fomina M.; Gadd G.M. (2003)

In the Earth's lithosphere, fungi are of fundamental importance as decomposer organisms, animal and plant pathogens and symbionts (e.g. lichens and mycorrhizas), being ubiquitous in sub-aerial and subsoil environments. The ...

The coarse-grained lunar meteorites, Yamato-793169 and Asuka-881757, represent a new type of low-Ti mare basalt. This paper reports the results of a U#Th#Pb, Sm#Nd, and Ar#Ar isotopic study of Yamato-793169 performed as ...

FURTHER EVIDENCE FOR LOW INTENSITY OF THE GEOMAGNETIC FIELD DURING THE EARLY CRETACEOUS TIME: USING THE MODIFIED SHAW METHOD AND MICROWAVE TECHNIQUE

Pan Y.; Zhu R.; Hill M.J.; Shaw J. (2004)

We report new absolute palaeointensity estimates using basalts from northeastern China (K/Ar age, 125-120 Ma) using the modified Shaw method in conjunction with the microwave technique. Samples for the palaeointensity ...

FURTHER EXPERIMENTAL EVIDENCE FOR A CRYSTALLITE SIZE EFFECT IN THE FES2COS2 SYSTEM

Tauson V.L.; Akimov V.V. (1993)

The experimental study of the miscibility gap in the FeS2CoS2 system at different particle sizes with previously reported theoretical data on the miscibility in small-crystallite binary systems gives evidence for a ...

FURTHER INVESTIGATIONS ON OPTIMIZED TAIL CORRECTION AND HIGH-PRECISION MEASUREMENT OF URANIUM ISOTOPIC RATIOS USING MULTI-COLLECTOR ICP-MS

Deschamps P.; Doucelance R.; Ghaleb B.; Michelot J.L. (2003)

In the present paper, we further examine the optimum conditions for rapid, precise and accurate determination of 234U/238U ratios in geological materials by multiple collector (magnetic-sector) inductively coupled plasma ...

FUSINITE OF FOSSIL COALS AS AN INFORMATION SOURCE ABOUT THE ANATOMY OF ANCIENT PLANTS

Kizil'stein L.Ya. (2006)
