Abstract. Sea-breeze fronts (SBFs) are frequently found to trigger deep convection. The convective updrafts near the SBF critical in this triggering process. Here, size and strength of an idealized investigated with large-eddy simulations. A central focus study is compare SBF, which substantially affected by ahead develop a typical boundary layer. It that larger than but have similar SBF. produ...

The effect of anodic oxidation of a NiTi shape memory alloy in sulfuric acid electrolyte on its surface characteristics was studied. Surface roughness was measured by roughness tester. Surface morphology was studied using optical microscopy (OM) and scanning electron microscopy (SEM). Corrosion behavior was specified by recording Potentiodynamic polarization cur...

the aim of this work was to investigate the effect of silica coating on bioactivity and biodegradability of hydroxyapatite. in this purpose, we firstly attempted to synthesis hydroxyapatite (ha) nanoparticles and its silica coated (si-ha) sample in collagen matrix using calcium chloride, sodium phosphate and sodium silicate. characterization of the sample was carried out using fourier transform...

C4 bumps are susceptible to electromigration failure due to large power-supply currents. Electromigration failure is exacerbated by manufacturing variability, which increases bump resistance and consequently the current draw in neighboring bumps. A typical solution entails adding redundant bumps while guard-banding the maximum current per bump. Instead, we propose a mixed-integer linear program...

We formalize within the dolce foundational ontology the Structure-Behavior-Function model (sbf) proposed by Ashok K. Goel and colleagues. Our work focuses in particular on the notion of function. This work on sbf is part of a larger project that includes the formalization of the concepts of function by Chandrasekaran and Josephson and by Stone and Wood. The overall goal is to make engineering f...

PCR-based differential screening was used to identify ethylene-induced genes in deep-water rice (Oryza sativa L.). One of the isolated cDNAs represented a novel protein, OsSBF1, with high homology to mammalian Na+/bile acid transporters and to sodium-dependent transporters from bacteria. One highly homologous protein and three less conserved homologues were identified in Arabidopsis thaliana in...

The effects of surface topography, processing, and environment conditions during tribological contact between Ti6Al4V titanium alloy UHMWPE friction pairs were systematically evaluated. Hence, in this research the polyethylene samples (blocks) having a constant roughness rubbed against counter-bodies (rollers) made with different surfaces. counter-samples manufactured using either dry machining...

We have obtained deep B and R-band CCD photometry for five dwarf elliptical galaxies that were previously identified on Schmidt films covering the region of the Centaurus A (Cen A) group. From a Fourier analysis of the R-band CCD images we determined the surface brightness fluctuation (SBF) magnitude ¯ m R for each stellar system. All magnitudes are similar and, given the small colour spread, s...

We have obtained deep B and R-band CCD photometry for five dwarf elliptical galaxies that were previously identified on Schmidt films covering the region of the Centaurus A (Cen A) group. From a Fourier analysis of the R-band CCD images we determined the surface brightness fluctuation (SBF) magnitude m̄R for each stellar system. All magnitudes are similar and, given the small colour spread, sugg...
