The efficiency of processes involving frictional contacts between surfaces is often characterized by wear rates or friction coefficients. However, the classification and forecasting in related a real industrial challenge that unsolved today. Hence, an on-line monitoring system able to classify rate can be crucial for many industries as it could help preventing catastrophic failures. Application...

A technique to perform two-wavelengths digital holographic microscopy (DHM) measurements with a single hologram acquisition is presented. The vertical measurement range without phase ambiguity is extended to the micron-range, thanks to the resulting synthetic wavelength defined by the beating of two wavelengths with a separation of about 80nm. Real-time dual-wavelength imaging is made possible ...

A DNA microarray representing nearly all of the unique sequences of human Chromosome 22 was constructed and used to measure global-transcriptional activity in placental poly(A)(+) RNA. We found that many of the known, related and predicted genes are expressed. More importantly, our study reveals twice as many transcribed bases as have been reported previously. Many of the newly discovered expre...

In this study, we reviewed the maximum and minimum temperature trends of Kathmandu valley over period 2011-2017. addition, average monthly were studied annually for same period, with data made available from Department Hydrology Meteorology (DHM) Nepal. The annual trended in direction, winter temperatures being lower summer higher. air found to be slightly rising at 0.097˚C/year 0.04˚C/year, re...

We have developed a digital holographic microscope (DHM), in a transmission mode, adapted to the quantitative study of cellular dynamics. Living cells in culture are optically probed by measuring the phase shift they produce on the transmitted wave front. The high temporal stability of the phase signal, equivalent to lambda/1800, and the low acquisition time (~20micros) enable to monitor cellul...

In the present study the effect of feeding the soybean-derived Bowman-Birk protease inhibitor (BBI) on dimethylhydrazine (DHM)-induced gastrointestinal tract and liver carcinogenesis in mice was examined. In this investigation we found the addition of 0.5 or 0.1% semipurified BBI or 0.1% purified BBI to the diet of DMH-treated mice resulted in a statistically significant suppression of angiosar...

Common cameras are only sensitive to the intensity of light, discarding an essential feature a light wave: its phase profile or, equivalently, wavefront profile. This Review focuses on rising imaging technique called quadriwave lateral shearing interferometry (QLSI), based simple use 2-dimensional diffraction grating, aka cross-grating, in front regular camera. We detail working principle QLSI ...

The aim in this paper is to present a research on the application of serious games for the design of laboratories in the oil and gas industries. The focus is in human virtual representation acquired from 3D scanning, human interaction, workspace layout and equipment designed considering ergonomics standards. The laboratory studies were simulated in Unity3D platform, which allows the users to co...
