They credit five "precision elements" to record incoming light (versus four in the already excellent iPhone 4 camera) and the inclusion of a larger f/2.4 aperture to bring in more light.
In the single-model approach, a p-convergent high-precision element is developed with three-dimensional elasticity theory.
Whereas, in the mixed-model approach, a p-convergent transition element is developed to connect the p-convergent high-precision elements for threedimensional response and p-convergent ESL (equivalent single layer) elements for two-dimensional response.
In this paper this issue is claridied quantitatively and qualitatively by developing a new mathematical model for the precision rolling element bearings from basic principles.
The present study shows good agreement with the previous work for thin panels for all boundary conditions as a result of using the high precision finite element.
Aerostatic guideways have been applied to precision machine elements.
The issue of an optimized, double-precision finite element GPU implementation of an explicit dynamics finite element solver for elastic shell problems in small strains and large displacements and rotations, using unstructured meshes, is here addressed.
Partial correlation coefficients are related to the precision matrix elements by Equation (1).
As commonly done, instead of directly estimating the precision matrix elements ω uv (n ), we estimate the partial correlation coefficients ρ(n ), where ρ uv (n ) is the correlation between gene u and gene v conditioned on the values of all the other genes.
He has developed energy saving double decker high-precision rolling-element bearings, and established the performance of these bearings both theoretically and experimentally.
Ultra-precision optical elements have high machining accuracy, and play very important roles in advanced optical systems, such as, the large astronomical telescope, the extreme ultraviolet lithography and the high power laser device [1 3].
