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...

Mineral dust plays a key role in both local and global climates. At high latitudes, atmospheric can affect ice-nuclei formation, surface reduce the albedo as well increase subsequent ice melting. As proxy for past climate, mineral is preserved cores, but few studies have examined deposited cores during Anthropocene, especially after 2000. We measured concentrations an core at southeastern dome ...

By thermally cycling through their transformation temperature range, coarse-grained polymorphic materials can be deformed superplastically, owing to the emergence of transformation mismatch plasticity (or transformation superplasticity) as a deformation mechanism. This mechanism is presently investigated under biaxial stress conditions during thermal cycling of unalloyed titanium, Ti-6Al-4V, an...

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...

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...

The lung-expanding action of the diaphragm is primarily related to the descent of the dome produced by the shortening of the muscle fibers. However, when the phrenic nerves in dogs are selectively stimulated at functional residual capacity, the muscle insertions into the lower ribs also move caudally. This rib motion should enhance the descent of the dome and increase the fall in pleural pressu...

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...

evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...

Metallic spherical dome shells have received much attention in recent years because they have proven to possess highly impressive optical properties. The expected distinctive changes occurring owing to quantum confinement of conduction electrons in these nanoparticles as their thickness is reduced, have not been properly investigated. Here we carry out a detailed analytical derivation of the qu...
