Three-dimensional (3D) measurement is an important means for robots to acquire information about their environment. Structure from Motion is one of these 3D measurement methods. The 3D reconstruction of objects in the environment can be obtained from pictures captured with single camera in Structure from Motion. Furthermore, the camera motion can be(More)
The sea surface wind speed (SSWS) derived by a microwave radiometer can be contaminated by changes of the brightness temperature owing to the angle between the sensor azimuth and the wind direction (Relative Wind Direction effect: RWD effect). have pointed out that the brightness temperature (BT) can change according to the angle between the sensor azimuth(More)
A 38-year-old man was admitted with coingestive heart failure due to infective endocarditis. Echocardiography with color Doppler imaging revealed severe aortic regurgitation, mitral valve premature closure and diastolic mitral regurgitation. The flow of the diastolic mitral regurgitation was directed to the posterior wall of the left atrium through just(More)
found no measurable bias (defined as GLI minus AMSR), while the standard deviation of difference is less than 1°C. In low water vapor conditions, the GLI SST has a positive bias less than 0.2°C, and in high water vapor conditions, it has a negative (positive) bias during the daytime (nighttime). The low spatial resolution of AMSR is another factor(More)
The development of alcohol use disorder (AUD) is related to various social, economic, cultural, environmental and hereditary factors. Several potential risk factors have been proposed for AUD in addition to alcohol consumption, including alcohol dehydrogenase2 (ADH2), acetaldehyde dehydrogenase2 (ALDH2), marital status, educational, occupational or past(More)
— Three-dimensional (3D) measurement methods are becoming more and more important to obtain information about the surrounding environment in many fields. Structure from Motion is one 3D measurement method using a single camera. This technique calculates the 3D reconstruction of objects from images captured by a single camera with motion. The camera motion(More)
