the molybdenum dicilicide is an intermetallic compound with two allotropies tetragonal ?-mosi2 and hexagonal ?-mosi2.the ?-mosi2 phase is established to 1900 ?c and ?-mosi2 phase from 1900 to 2050 ?c. this material has considerable properties that provide different applications in different industries such as air-space industry and gas turbines. the molybdenum synthesis can be down in various w...

In 1839, the daguerreotype photographic process was first presented to the scientific community in France. The technology spread rapidly and was widely used around the globe until roughly 1860. Image formation can be generalized into four steps: 1) exposing silver-plated copper to an iodine plus or minus another halogen vapor(s), 2) further exposing the sensitized plate to visible light within ...

We present a semi-parametric approach to photographic image synthesis from semantic layouts. The approach combines the complementary strengths of parametric and nonparametric techniques. The nonparametric component is a memory bank of image segments constructed from a training set of images. Given a novel semantic layout at test time, the memory bank is used to retrieve photographic references ...

The purpose of our study is to introduce a new method for depth of field blur simulation used for compositing real and synthetic images in a realistic way. Existing methods do not simulate accurately the depth of field blur produced by photographic equipment. The problem is twofold: photometric and geometric. Existing methods based on convolution do not produce a realistic photometric rendering...

Torque models are presented for five mechanical knobs that were characterized using the rotary haptic camera shown Figure 1. Non-linear least squares fitting was used to estimate model parameters for position, velocity, and acceleration model parts. Additionally, two simulated knobs were mod-eled to test the accuracy of the characterization algorithm. A haptic camera does for touch what a typic...
