For an operator generating a group on $$L^p$$ spaces transference results give bounds the Phillips functional calculus also known as spectral multiplier estimates. In this paper we consider specific generators which are abstraction of first order differential operators and prove similar estimates assuming only that is bounded $$L^2$$ rather than . We R-bounded Hörmander result by abstract Sobol...

We show how to formalize approximate counting via hash functions in subsystems of bounded arithmetic, using variants of the weak pigeonhole principle. We discuss several applications, including a proof of the tournament principle, and an improvement on the known relationship of the collapse of the bounded arithmetic hierarchy to the collapse of the polynomial-time hierarchy.

This article describes the design of approximate array multipliers by making vertical or horizontal cuts in an accurate multiplier followed different input and output assignments within multiplier. We consider a digital image denoising application show how combinations affect quality denoised images. several for synthesis. The were described Verilog hardware description language synthesized Syn...

Graph cut algorithms [9], commonly used in computer vision, solve a first-order MRF over binary variables. The state of the art for this NP-hard problem is QPBO [1, 2], which finds the values for a subset of the variables in the global minimum. While QPBO is very effective overall there are still many difficult problems where it can only label a small subset of the variables. We propose a new a...

and Applied Analysis 3 Step 1. Let F {a} be singleton. Then, there are u ∈ U and v ∈ V such that ‖uv‖ < M, and ‖ u, v, a − a‖ < M 1 . 2.2 Letting w uv ◦ uv, then ‖ uv ◦ uv, a − a‖ ‖ u, v, u, v, a − a − u, v, a − a ‖ < . 2.3 Step 2. Let F {a1, a2}. There is a u1, v1 ∈ U × V such that ‖ u1, v1, a1 − a1‖ < / 1 M , and for u1, v1, a2 − a2 ∈ A there is a u2, v2 ∈ U × V such that ‖ u2, v2, u1, v1, a2...
