Singhbhum Shear Zone (SSZ) is a geologically rich belt with structures like faults and folds being the distinctive features. Due to these characteristics this area has been an important centre of studies since past few decades. With the advent of Remote Sensing and GIS, it has been possible to study and interprete geological setting of any area in the laboratory itself without even visiting the...

Vibration damping in polycrystalline TbDy alloys was studied at cryogenic temperatures. Mechanical hysteretic losses were measured at various strains, frequencies, and loading configurations at 77 K. Some textured TbDy materials demonstrated 22.6% energy dissipation in mechanical measurements at low frequency ~0.01 Hz! and a mean logarithmic decrement of 0.23 at a higher frequency ~25 kHz!. Ult...

Techniques to measure the deformation of finger pad when rubbing material surfaces are important for the analysis of textural sensations and development of tactile texture displays. However, such measurements are difficult because when the finger pad is in contact with the material surfaces, it is not exposed for measurement. We developed a technique to estimate finger pad shear deformation by ...

Microscopic images of leaves, collected from Mona Island dry forest (which is located between Puerto Rico and the Dominican Republic), were analyzed. For each leaf side an image was obtained at two magnifications (200x and 400x). This resulted in four samples of images showing a wide variety of textures and stomata patterns. For each group of images we used the gray-level co-occurrence method t...

Flow induced mineral alignment in the Earth s mantle affects the nature of seismic wave propagation. Since measurements of seismic travel-time and shear wave splitting are a key means by which the structure of the upper mantle can be imaged, it is important to understand the factors that contribute to variability in elastic properties. Seismic anisotropy associated with lattice preferred orient...
