Discrete media (DM) data throughput is vital to systems that need to support the heterogeneity and variety of data found in interactive hypermedia and digital library applications. Therefore, a multimedia server's ability in delivering a high DM data throughput without degrading its CM data throughput deserves more attention. In this paper, we address this issue by optimizing the use of disk ba...

introduction main part of energy consumption in agricultural mechanization is tillage operations therefore optimization of energy consumption in tillage operation is very important. a management method for system to optimize in agriculture is simple additive weighting (saw) methodology that this method can operate according to criteria of the systems. this method states that, which system has b...

PURPOSE To investigate the effect of various riboflavin/ultraviolet light (UVA) crosslinking (CXL) protocols on corneal enzymatic resistance. METHODS A total of 66 enucleated porcine eyes, with the corneal epithelium removed, were divided into 6 groups. Group 1 remained untreated. Groups 2 to 6 received riboflavin/dextran for 30 minutes. Group 3 underwent standard CXL (SCXL) with 3 mW/cm(2) U...

Sgr A* is a compact radio source at the Galactic Center, thought to be the radiative manifestation of a 2.6 × 106 M⊙ supermassive black hole. At least a portion of its spectrum—notably the mm/sub-mm “bump”—appears to be produced within the inner portion (r < 10 rS) of a hot, magnetized Keplerian flow, whose characteristics are also consistent with the ∼ 10% linear polarization detected from thi...

We present observations of CO overtone bandhead emission toward four massive Young Stellar Objects (spectral type O6–B5). The high signal-to-noise ratio K-band spectra were obtained with VLT-ISAAC at a resolution ∆v = 30 km s, sufficient to resolve the bandheads, but not the individual J-lines. We are able to explain the shape of the lines by assuming a simple isothermal keplerian disk model se...

This study tested whether 4-month-old infants respond primarily to objects' physical or retinal image sizes. In the study's main experiment, infants were habituated to either a 6-cm-diameter disk at a distance of 18 cm or a 10-cm disk at 50 cm. They were then given 2 test trials in which the 6- and 10-cm disks were presented side by side at a distance of 30 cm. For each infant, one test object ...

We present the results of exploratory HST observations to detect the emission lines of ions in the β Pictoris disk with the spectrograph slit placed off the star. Possible emission lines from Fe ii have been detected at ∼ 10 −14 erg cm −2 s −1 at 0.5 from β Pictoris, which would suggest a total Fe ii density of > ∼ 2 · 10 −2 cm −3 at 10 AU. This detection needs confirmation. If real, it require...
