Scaling Limits for Mixed Kernels

Let μ and ν be measures supported on (−1, 1) with corresponding orthonormal polynomials { pn } and {pn} respectively. Define the mixed kernel K n (x, y) = n−1 ∑ j=0 pμj (x) p ν j (y) . We establish scaling limits such as lim n→∞ π √ 1− ξ √ μ′ (ξ) ν′ (ξ) n K n ( ξ + aπ √ 1− ξ n , ξ + bπ √ 1− ξ n ) = S ( π (a− b) 2 ) cos ( π (a− b) 2 +B (ξ) ) , where S (t) = sin t t is the sinc kernel, and B (ξ) ...

Psychophysical Scaling'"

their helpful criticisms of a preliminary draft of this chapter. A special word of thanks is due Dr. Stevens, u~ho, in addition to discovering seueral errors of fact and a nutnber of stylistic blunders, forced us to reconsider some of our views on various aspects of scaling. His comments coupled wzth our own misgivings resulted in a complete revision oj'the section on magnitude estimation and t...

Multiscale Hybrid-Mixed Method

This work presents a priori and a posteriori error analyses of a new multiscale hybridmixed method (MHM) for an elliptic model. Specially designed to incorporate multiple scales into the construction of basis functions, this finite element method relaxes the continuity of the primal variable through the action of Lagrange multipliers, while assuring the strong continuity of the normal component...

Investigating Pilot Performance Using Mixed-Modality Simulated Data Link

OBJECTIVE General aviation (GA) pilot performance utilizing a mixed-modality simulated data link was objectively evaluated based on the time required in accessing, understanding, and executing data link commands. Additional subjective data were gathered on workload, situation awareness (SA), and preference. BACKGROUND Research exploring mixed-modality data link integration to the single-pilot...
