COMPARISON OF VERTICAL AND VOLUMETRIC SWELLS OF COMPACTED EXPANSIVE SOILS
"... ABSTRACT: Swell percentage of expansive soils is commonly obtained from oedometer swell tests under fully lateral restraint condition. In situ heave, however, is not a onedimensional volume change but more likely a threedimensional process. Consequently, surface heave predicted from results of oed ..."

obtained from oedometer swell tests. This paper describes a laboratory testing procedure by which the vertical and the volumetric swells of compacted expansive soil samples were concurrently measured using a hydraulic triaxial stress path apparatus. A set of triaxial swell tests was conducted and the ratio
Complete discrete 2D Gabor transforms by neural networks for image analysis and compression
, 1988
"... A threelayered neural network is described for transforming twodimensional discrete signals into generalized nonorthogonal 2D “Gabor” representations for image analysis, segmentation, and compression. These transforms are conjoint spatial/spectral representations [lo], [15], which provide a comp ..."

complete image description in terms of locally windowed 2D spectral coordinates embedded within global 2D spatial coordinates. Because intrinsic redundancies within images are extracted, the resulting image codes can be very compact. However, these conjoint transforms are inherently difficult to compute

, 2002
"... Abstract: This paper addresses the behaviour of compacted expansive soils under swellshrink cycles. Laboratory cyclic swellshrink tests were conducted on compacted specimens of two expansive soils at surcharge pressures of 6.25, 50.00, and 100.00 kPa. The void ratio and water content of the speci ..."

"... AbstraetThe limitations of existing methods for the prediction of swelling behavior of compacted softs are examined. Both the purely theoretical pproach and the purely empirical approach are found to be inadequate. The present study is based on a semiempirical pproach in which a model of swelling ..."

"... We investigate degeneracies of BPS states of Dbranes on compact CalabiYau manifolds. We develop a factorization formula for BPS indices using attractor flow trees associated to multicentered black hole bound states. This enables us to study background dependence of the BPS spectrum, to compute e ..."

"... . This paper provides a framework for studying the dynamics of commuting homeomorphisms. Let ff be a continuous action of Z d on an infinite compact metric space. For each subspace V of R d we introduce a notion of expansiveness for ff along V , and show that there are nonexpansive subspaces in ever ..."
