Introduction: Three landslides sites located within the Valles Marineris (0o-20o S and 30o-90o W), studied using Viking data [1,2,3] have been reexamined using MOLA topography data and MOC images. Previously we have validated the extent to which the relative value and absolute variations of empirical parameters derived from Chezy-type models describe the behavior of the General’s slide debris f...

Fluorescence imaging is a powerful technique with diverse applications in intraoperative settings. Visualization of three dimensional (3D) structures and depth assessment of lesions, however, are oftentimes limited in planar fluorescence imaging systems. In this study, a novel Fluorescence Imaging Topography Scanning (FITS) system has been developed, which offers color reflectance imaging, fluo...

The nature of tip-sample interaction forces in atomic force microscopy (AFM) phase imaging strongly affects the resolution of proton conducting domains mapped at the surface of Nafion membranes. Images acquired in repulsive mode overestimated the area of individual proton conducting domains by a factor of 4 (360 vs 90 nm(2)) and underestimated the number of these domains by a factor of 3 (0.9 d...

[1] Microscopic simulations of fracture dissolution are reported, taking account of the explicit topography of the pore space, the transport of reactants and products, and the chemical kinetics at the solid surfaces. A three-dimensional numerical model has been constructed, in which the fluid velocity field is calculated with an implicit lattice-Boltzmann method, and the transport of dissolved ...

The suggestion that there exist causally disconnected universes or subuniverses to explain the values of physical parameters such as the cosmological constant is discussed. A statistical model of the string landscape/topography is formulated using a stochastic Langevin equation for string and supergravity potentials. A Focker-Planck equation for the probability density of superpotentials is der...

Increased demand for treatment of skin wrinkles has led to a proliferation of different pharmaceutical and surgical treatment methods. However there still remains a lack of quantitative, objective, easily utilizable and reproducible wrinkle classification system by which these treatments can be studied and compared. We propose the use of a novel photometric stereo based technique as a potential...

Long’s equation describes two dimensional stratified atmospheric flow over terrain which is represented by the geometry of the domain. The solutions of this equation over simple topography were investigated analytically and numerically by many authors. In this paper we derive a new terrain following formulation of this equation which incorporates the terrain as part of the differential equation...

The overall objectives of our project are 1) to determine the characteristics of channel features that can form when the present continental shelf is subaerially exposed during low sea-level conditions and 2) to determine whether these features would be buried when sea-level returned to its present position and, if so, how deeply. During FY01, our objectives have been to adapt the model to run ...

Double-sided high-sloped structured surfaces such as V-groove surfaces and Fresnel lenses are widely used in optical fibre positioning, retro-reflection, grating, light guiding and light concentration for solar power installation. Both the surface finish as well as the dimensions of the structured surfaces play important roles in the quality of the final products. Numerous efforts have been put...
