This paper focuses on the development of high temperatures in the cutting zone during high performance grinding. In order to identify the infl uence of grinding temperature on surface integrity, temperatures were measured in the workpiece surface layer under diff erent machining conditions. Beside this, under the same conditions, the surface layer properties of the workpiece material were deter...

Gale Crater, the Mars Science Laboratory (MSL) landing site, contains a central mound, named Aeolis Mons (informally Mount Sharp) that preserves 5 km of sedimentary stratigraphy. Formation scenarios include (1) complete filling of Gale Crater followed by partial sediment removal or (2) building of a central deposit with morphology controlled by slope winds and only incomplete sedimentary fill. ...

High-resolution core-level photoemission data from the 1s level of Li~110! have been obtained between 77 and 280 K. Analysis of the data reveals a significant difference in the zero-temperature phonon broadening between the bulk and surface atoms but only a small difference in the effective surface and bulk Debye temperatures. This latter result is in good agreement with an embedded-atom-method...

In 1999, four monitoring stations were permanently moored on Lake Tahoe, California–Nevada. Each monitoring station provides near-real-time measurements of the surface skin temperature and bulk temperature on a near-continuous basis. Day and night data, acquired over Lake Tahoe from March to August 2000 with the second Along-Track Scanning Radiometer (ATSR-2), have been analyzed, and sets of co...

tio2 nanorods are synthesized by a thermal corrosion. in present work, synthesis of tio2 nanorods in anatase, rutile and ti8o15 phases, by using the sol-gel method and alkaline corrosion are reported. the morphologies and crystal structures of tio2 nanorods are characterized by use of field emission scanning electron microscopy, atomic force microscopy and x-ray diffractometer techniques. the o...

in this work, artificial neural network (ann) has been employed to propose a practical model forpredicting the surface tension of multi-component mixtures. in order to develop a reliable modelbased on the ann, a comprehensive experimental data set including 15 ternary liquid mixtures atdifferent temperatures was employed. these systems consist of 777 data points generally containinghydrocarbon ...

The influence of programming strain and temperature on the shape memory effect and surface morphology in programmed polycarbonate (PC) samples via uni-axial stretching is investigated. It is found that the samples programmed at around the glass transition start temperature not only have micro-cracks on their surface, but also show a necking phenomenon. Furthermore, the surface of the necked are...

This study employs NASA’s recent satellite measurements of sea-surface temperatures (SSTs) and sea-level winds (SLWs) with missing data filled-in by Singular Spectrum Analysis (SSA), to construct empirical models that capture both intrinsic and SST-dependent aspects of SLW variability. The model construction methodology uses a number of algorithmic innovations that are essential in providing st...
