The analytical solutions of wave induced horizontal and vertical forces on perforated caissons resting on porous elastic seabed have been established. The solution in the seabed is divided into a symmetric part and an anti-symmetric part. A numerical experiment has been carried out to examine the effects on horizontal forces, vertical forces and phase lags between them due to the relative wave ...

for the characteristics of horizontal fractures in shallow low-permeability oil layers after hydraulic fracturing in multilayer reservoirs, horizontal fractures are taken equivalent to an elliptical cylinder with the reservoir thickness using the equivalent permeability model; then, upon the elliptic seepage theory, the seepage field which has led by a vertical well with horizontal fractures is...

When noise checks are small, spatial noise mimics the effect of white noise in grating detection in the sense that contrast energy threshold is directly proportional to the spectral density of noise and the physical signal-to-noise ratio at threshold thus remains constant. We investigated how the size and shape of noise checks affect the masking properties of noise by using vertical and polar-c...

PURPOSE To investigate the difference between two-dimensionally measured disc diameters (DDs) based on fundus images and three-dimensionally measured DDs based on enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS The DDs were three-dimensionally measured on EDI-OCT images of optic nerve heads and two-dimensionally measured on near-infrared reflectance fundus images in 90 ...

Brain-derived neurotrophic factor (BDNF) is known to be crucial for the development of peripheral vestibular neurons. However, the maturation profile of the BDNF signal transducing receptor, tyrosine kinase B (TrkB) in functionally activated otolith-related vestibular nuclear neurons of postnatal rats remains unexplored. In the present study, conscious Sprague-Dawley rats (P4 to adult) were sub...

a numerical investigation of laminar mixed convection heat transfer in a shallow two-sided lid driven rectangular enclosure of aspect ratio 5, (ar=5) is executed. the natural convection effect is sustained by subjecting the bottom wall to a higher temperature than its top counterpart. in addition, the two horizontal walls of the enclosure are moving in different directions and the two vertical ...

an extended octagonal ring (eor) transducer was designed and developed to measure forces inside the compression chamber of a large square baler in different directions. the transducer was calibrated by applying forces in three directions simultaneously and independently. the sensor revealed excellent linearity along with small cross sensitivities. horizontal and vertical primary sensitivities o...

MIPAS is a very high spectral resolution sounder (0.025 cm wavenumber resolution) onboard ESA's Envisat satellite. It provides 59,605 spectral points or channels in 5 bands in the range 685-2410 cm. In the nominal scanning configuration, it gives one scan about every 5o latitude for 17 tangent altitudes between 6 and 68 km. The field of view (FOV) is 3 km in the vertical and 30 km in the horizo...

This paper describes how the visual and acoustic characteristics of some Italian phones (/’a/, /b/, /v/) are modified in emotive speech by the expression of joy, surprise, sadness, disgust, anger, and fear. In this research we specifically analyze the interaction between labial configurations, peculiar to each emotion, and the articulatory lip movements of the Italian vowel /’a/ and consonants ...

Understanding the evolution of melt ponds on Arctic sea ice is important for climate model parameterisations, weather forecast models and process studies involving mass, energy and biogeochemical exchanges across the ocean–sea ice–atmosphere interface. A field campaign was conducted in a region of level first-year sea ice (FYI) in the central Canadian Arctic Archipelago (CAA), during the summer...
