The article considers the results of application methods correlation analysis data decryption satellite images, gravitational field, heat flux values and ground-based geological geophysical (geotectonic, seismological) measured in region Pre-Caspian concentric depression. As a result, local morphological structures with high gravity field flow, promising for search new oil gas fields, were iden...

17O-excess (?17O = ?17O ? 0.52 × ?18O) of sulfate trapped in Antarctic ice cores has been proposed as a potential tool for assessing past oxidant chemistry, while insufficient understanding atmospheric formation around Antarctica hampers its interpretation. To probe influences regional specific we compared year-round observations ?17O non-sea-salt aerosols (?17O(SO42?)nss) at Dome C and Dumont ...

BACKGROUND The technique of vertical dome division or tip defining, involves incising the lateral crura and vestibular skin at or lateral to the dome or tip defining point. The incision divides the lower lateral cartilage into a lateral segment and a medial segment, which are advanced anteriorly and sutured together to increase tip projection. The present study aimed at assessing a new vertical...

As engineering design becomes more and more complex, we predict that the field will look to immersive environments as a way to create more natural interactions with design ideas. But, helmets are bulky and awkward. A better solution for immersive design is a partial dome. Originally the exclusive domain of flight simulators, dome projection is now being brought to the masses with less expensive...

Abstract Inverse medium problems involve the reconstruction of a spatially varying unknown from available observations by exploring restricted search space possible solutions. Standard grid-based representations are very general but all too often computationally prohibitive due to high dimension space. Adaptive spectral decompositions instead expand in basis eigenfunctions judicious elliptic op...

BACKGROUND AND PURPOSE Our goal was to characterize the geometry of simple-lobed cerebral aneurysms and to find the absolute size of these lesions from angiographic tracings. METHODS Measurements of angiographic neck width (N), dome height (H), dome diameter (D), and semi-axis height (S) were obtained from tracings of 87 simple-lobed lesions located at the basilar bifurcation (BB), middle cer...

BACKGROUND AND PURPOSE The ability to discriminate between ruptured and unruptured cerebral aneurysms on a morphological basis may be useful in clinical risk stratification. The objective was to evaluate the importance of inflow-angle (IA), the angle separating parent vessel and aneurysm dome main axes. METHODS IA, maximal dimension, height-width ratio, and dome-neck aspect ratio were evaluat...

Shallow high resolution 2-D and 3-D seismic reflection techniques are assisting in the subsurface delineation of a surface collapsc feature (sinkhole) at Weeks Island. Louisiana. Seismic reflection surveys were conducted in March 1994. Data from walkaway noise tests were used to assist selection of field recording parameters. The top of the salt dome is about 180 ft below ground surface at the ...

Conventional images of tourist sites are trimmed off the unnecessary scenery from the whole scenery in the fixed viewing angle of the cinematographer’s intention. Therefore, when people visit a tourist destination, they are often disappointed about the gap between video image and actual sight. In order to eliminate this gap, we developed the Digital Dome Theatre System in 2009. It can project u...
