The Greenhouse Gases Observing Satellite (GOSAT) was launched on January 23, 2009, to monitor global atmospheric levels of CO2 and CH4 from space. GOSAT started initial operation its instruments after an satellite system check. Although the radiant data obtained by are currently in preliminary stages calibration validation, spectral absorption features clearly identifiable. An retrieval these gaseous concentrations performed for measurement scenes cloud-free conditions over land. These...
This report describes a validation study of Greenhouse gases Observing Satellite (GOSAT) data processing using ground‐based measurements the Total Carbon Column Network (TCCON) as reference for column‐averaged dry air mole fractions atmospheric carbon dioxide (X CO2 ). We applied photon path length probability density function method to validate X retrievals from GOSAT obtained during 22 months starting June 2009. permitted direct evaluation optical modifications due light scattering that...
In this study, we examined the effects of sensory inputs visual-vestibulosomatosensory conflict induced by virtual reality (VR) on subjective dizziness, posture stability and visual dependency postural control in humans. Eleven healthy young volunteers were immersed two different VR conditions. condition, subjects walked voluntarily with background images interactive computer graphics proportionally synchronized to their walking pace. kept still, but that experienced condition presented. The...
Abstract In this work, the Greenhouse Gases Observing Satellite ( GOSAT ) Thermal and Near-infrared Sensor for Carbon Observation–Cloud Aerosol Imager (TANSO-CAI) cloud screening results, which are necessary retrieval of carbon dioxide (CO 2 methane (CH 4 gas amounts from TANSO–Fourier Transform Spectrometer (FTS) observations, compared with results Aqua /Moderate Resolution Imaging Spectroradiometer (MODIS) in four seasons. A large number pixels, acquired both satellites nearly coincident...
This report is the second in a series of companion papers describing effects atmospheric light scattering observations carbon dioxide (CO 2 ) by Greenhouse gases Observing SATellite (GOSAT), orbit since 23 January 2009. Here we summarize retrievals from six previously published algorithms; retrieving column‐averaged dry air mole fractions CO (X CO2 during 22 months operation GOSAT June First, compare data products each algorithm with ground‐based remote sensing Total Carbon Column Network...
Differences in the acetylcholine (ACh)‐induced endothelium‐dependent relaxation and hyperpolarization of mesenteric arteries Wistar Kyoto rats (WKY) stroke‐prone spontaneously hypertensive (SHRSP) were studied. Relaxation was impaired preparations from SHRSP tendency to reverse observed at high concentrations ACh these preparations. partly blocked by N G ‐nitro‐ L ‐arginine ( ‐NOARG, 100 μ M ) and, presence response higher ACh, even WKY. The remaining ‐NOARG also smaller SHRSP. or WKY...
Because a synoptic overview facilitates understanding of the temporal and spatial changes in global distribution greenhouse gases, we developed statistical estimation method using kriging. Level 3 (L3) data products for Greenhouse Gases Observing Satellite (GOSAT) Thermal And Near infrared Sensor Carbon Observation (TANSO) Fourier Transform Spectrometer (FTS) Short Wave Infrared (SWIR) were generated from column-averaged, dry-air mole fractions carbon dioxide (XCO2) methane (XCH4) TANSO-FTS...

A new power supply which suppresses harmonic currents is proposed. The circuit made up by inserting a choke coil and transformer winding between the bridge rectifier input capacitor of an ordinary input-type supply. characteristics use like switch (a magnetic switch), has function to improve factor suppress currents. As this MS only one (MOSFET) control circuit, whole simple, inexpensive, meets IEC 1000-3-2 Class D standards concerning switching supplies.
TiN particle-dispersed Si3N4 ceramics are applied to bearing materials because of their excellent mechanical and thermal properties, chemical stability, etc. In particular, hybrid bearings composed metals more popular low production costs. such bearings, control abrasive wear by hard particles is required. The objective this study development nanoparticle-dispersed that cause damage the mating metals. order disperse nanoparticles in ceramics, TiO2 were mixed treatment. TEM observation showed...
The present study investigates whether VIMS, which can be induced in 2D images, is affected by stereoscopic presentation. To do this, we conducted an experiment to measure the effects psychologically and physiologically. Visual stimulus was computer graphics that simulates traveling along streets with additional pitch roll motion for 10 minutes. were presented as either stereoscopic, "3D", images or "2D" images. Before/after during each trial, psychological physiological measurements...
A variable speed drive system is studied which consists of the inverter-fed permanent magnet field synchronous motor without a rotor position sensor and rotating sensor. method explained, determines angles at standstill or conditions several by measuring instantaneous values phase voltages currents. The experimental results obtained prototype are compared with those an ordinary DC brushless servo tachogenerator.
(13)CO(2) is produced on metabolism of (13)C-labelled-pantoprazole ([(13)C]-pantoprazole) by CYP2C19.To investigate whether the [(13)C]-pantoprazole breath test can predict CYP2C19 status and efficacy proton pump inhibitors (PPIs) in Japanese.We classified 110 healthy volunteers as rapid metabolizers (RM), intermediate (IM) or poor (PM) genotyping. Breath samples were collected at 10-min intervals for 60 min after dosing with 100 mg [(13)C]-pantoprazole. Changes carbon isotope ratios...
Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a high spatial resolution multi-spectral imaging radiometer on NASA's Terra satellite. Observational performance of the ASTER instrument was examined by using actual images, it confirmed that has excellent radiometric geometric performance. obtains data target observation based upon acquisition requests.

A temperature controlled pavement has a significant requirement for preventing road from freezing, and avoiding winter traffic accidents at specific places. For example, slip accident tunnel mouth frequently occurs in causes serious danger human life heavy jam. Horizontal U-Tube (HUT) heating system was introduced order to prevent associated with freezing the west side of Nanaori-Toge tunnel, Aizu-bange, Fukushima Prefecture Japan. group U-tubes were buried depth 1.2 m ground central part...
The authors describe speech segmentation and clustering algorithms based on speaker features, where speakers, the number of context are unknown. Several problems formulated their solutions proposed. As in simpler case, when segmentations known, output probability algorithm is In case unknown segmentation, an ergodic HMM (hidden Markov model)-based technique applicable. Both cases evaluated using simulated multispeaker dialogue data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
