zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

PURPOSE To examine the association of personal values, the built environment, and auto availability with walking for transportation. SETTING Participants were drawn from 11 U.S. metropolitan areas with good transit services. SUBJECTS 865 adults who had recently made or were contemplating making a residential move. MEASURES Respondents reported if walking was their primary mode for nine tr...

As high performance computing (HPC) heads towards the exascale era, the computing power surges tremendously and applications will scale to hundreds of thousands cores. Consequently, the amount of data processed and generated will increase dramatically. Nowadays, a parallel shared file system is a must have for a supercomputer. To utilize I/O effectively is essential for an application to scale ...

The localized plastic flow auto-waves observed for the stages of easy glide and linear work hardening in a number of metals are considered. The propagation rates were determined experimentally for the auto-waves in question with the aid of focused-image holography. The dispersion relation of quadratic form derived for localized plastic flow auto-waves and the dependencies of phase and group rat...

Any theory that have a global spontaneously broken symmetry will imply the existence of very light neutral bosons or massless bosons (sometimes called Majorons). For most of these models we have neutrino-Majoron couplings, that appear as additional branching ratios in decays of mesons and leptons. Here we present an updated limits on the couplings between the electron, muon and tau neutrinos an...

The maskless photolithography device we developed requires no photomask, by modifying Liquid Crystal Display (LCD) projector optics from magnified to reduced projection. The second-generation device we developed produces a practical centimeter-scale micropattern by dividing a large mask pattern and divisionally exposing it synchronized with an auto-XY stage, applying it to cell micropattern and...

In this paper, we propose a new approach to detect salient traffic signs, which is based on visual saliency and auto-generated strokes for image segmentation. The proposed algorithm deals with two tasks on detecting traffic signs: auto-location and auto extraction. Firstly, inspired by recent work of visual saliency detection, we obtain the location of traffic signs in a natural image by multi-...

Scalability is an important characteristic of cloud computing. With scalability, cost is minimized by provisioning and releasing resources according to demand. Most of current Infrastructure as a Service (IaaS) providers deliver thresholdbased auto-scaling techniques. However, setting up thresholds with right values that minimize cost and achieve Service Level Agreement is not an easy task, esp...
