This study is an initial investigation on the capability of multispectral imaging to capture subtle spectral information that would enable the automatic delineation between the eosinophilic esophagitis and other eosin stained tissue components, especially the RBCs. In the method, a principal component analysis (PCA) was performed on the spectral transmittance samples of the different tissue com...

objective: some of the adverse effects of aspirin including peptic ulcers, gastrointestinal bleeding and aspirin resistance compelled researchers to find a suitable alternative with fewer adverse effects. in this clinical trial, we aimed to find the effective antiplatelet dose of garlic. materials and methods: this randomized controlled clinical trial (rct) was conducted on 62 healthy volunteer...

We address the design, fabrication, and characterization of transmittance filters for the Ionosphere Photometer instrument (IP), developed by the Center for Space Science and Applied Research (CSSAR). IP, a payload of Feng-Yun 3D meteorological satellite, to be launched on 2016, is aimed to perform photometry measurements of Earth’s ionosphere by the analysis of the OI (135.6 nm) spectral line ...

We describe a low-pass filter that provides high in-band transmittance and excellent rejection at ν > 100 cm(-1). The transmittance of the filter components was measured at liquid-helium temperatures from 10 to 10,000 cm(-1). The total transmittance is >50% for ν < 50 cm(-1) and is calculated to be <10(-9) for ν > 300 cm(-1). The filter was successfully used in a liquid-helium-cooled, rocketbor...

Considering the problem of color distortion caused by the defogging algorithm based on dark channel prior, an improved algorithm was proposed to calculate the transmittance of all channels respectively. First, incident light frequency’s effect on the transmittance of various color channels was analyzed according to the Beer-Lambert’s Law, from which a proportion among various channel transmitta...

Instrumentation is described that has been constructed at the National Institute of Standards and Technology (NIST) for the measurement of regular re ̄ectance and transmittance over the 2±25 mm wavelength region. This includes both specialized accessories used with Fourier-transform infrared (FT-IR) spectrometers and laser-based systems for high optical density transmittance measurements. The FT...

Conclusion: This work has found that AU films have better transmittance than Ag and AI. The 120 , & Au films have -60% transmittance compared to 70% for ITO. Au films with transmittances reaching 80% were also obtained with a corresponding degradation in resistance. The most important aspect to note is that Au films may have promise as transparent contacts. The resistance and transmittance did ...

Transmittance of electromagnetic waves with normal incidence in one-dimensional plasma photonic crystals is studied numerically based on the invariant imbedding method. Wave transmittance as a function of wave frequency shows the appearance of forbidden band gaps, which are conspicuous in photonic crystals. We also demonstrate that the small modification of plasma photonic crystal leads to diff...

For the first time Rigorous Coupled Wave Analysis (RCWA) has been applied to the analysis of the transmittance spectra for the determination of critical dimension (CD) of phase-shift photomasks. The use of transmittance spectra proved to be instrumental in improving the sensitivity of the measurement to minor (sub-nanometer) changes in the width of the trench. We present a novel unique metrolog...

A series of experiments was performed to determine how the visual system computes the transmittance of inhomogeneous surfaces and media. Previous work (Anderson, B. L. (1999) Stereoscopic surface perception. Neuron, 26, 919-928; Anderson, B. L. (2003) The role of occlusion in the perception of depth, lightness, and opacity. Psychological Review, 110, 762-784) has suggested that the visual syste...
