A solution is developed for the evolution of buildup, steady, and postarrest dissipative pore-fluid pressure fields that develop around a finite-radius conical penetrometer advanced in a saturated linearly elastic porous medium. The analog with cone penetrometer testing is direct and is used to enable continuous distributions of permeability and diffusivity to be determined with depth. This ana...

The objective of the present work is to demonstrate the effect of pore structure on fluid transport and electrical properties of homogeneous or dual-porosity pore structures for drainage conditions. To this end, a pore network numerical simulator is used that calculates multiphase flow and electrical properties taking into account the pore structure specificities. The characteristics of the 3-D...

Any collection of $d$-dimensional cubes total volume not greater than $2^{1-d}$ can be packed into the unit cube $I^d$ so that uncovered part contains a edge length $1-\sqrt[d]{2}/2$. To achieve this result, wel

Much effort in scientific visualization is put towards the representation and communication of three-dimensional objects. Typically, an investigator labors in front of a graphics workstation, twiddling knobs and flipping switches until meaningful views of the object are created. Once the investigator has found the correct representation of the data, the problem arises of how to communicate this...

Some landslides move imperceptibly downslope, whereas others accelerate catastrophically. Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity. Wet sandy soil with porosity of about 0.5 contracted during slope failure, partially liquefied, and accelerated within 1 second to speeds over 1 meter per second....

There are two main approaches for pore pressure estimation: geological using basin modeling and geophysical using seismic velocity. In this paper, seismic velocity was used for pore pressure estimation. The impact of the input data quality in terms of signal-to-noise ratio (SNR) and frequency bandwidth on the accuracy of seismic velocity analysis and, ultimately, the reliability of pore pressur...

In this thesis we study the problems of distance approximation to monotonicity and distance approximation to convexity. Namely, we are interested in (randomized) sublinear algorithms that approximate the Hamming distance between a given function and the closest monotone/convex function. For the monotonicity property, we focus on functions over the d-dimensional hyper-cube, [n]d, with any finite...

A collection H of integers is called an aane d-cube if there exist d + 1 positive) : In 1969, Szemer edi found a density result for aane cubes, namely, that for any positive integer d, there exists a constant c so that if A f1; 2; : : :; ng and jAj cn 1? 1 2 d , then A contains an aane d-cube. Using extremal hypergraphs, we ooer an entirely diierent proof of this fact (though with worse constan...

In this study, shaking table tests are performed to investigate the behavior of excess pore water pressure in different soft soil-foundations of soil-structure interaction (SSI) system. The variation of the behaviors under cycled minor shock is observed. Moreover, The generation and variation mechanism of excess pore water pressure under earthquake excitation in different soft soilfoundations a...

We prove that for d > 1 the information rate of the perfect secret sharing scheme based on the edge set of the d-dimensional cube is exactly 2/d. Using the technique developed, we also prove that the information rate of the infinite d-dimensional lattice is 1/d.
