Spectral efficiency and optimal medium access control of random access systems over large random spreading CDMA
This paper analyzes the spectral efficiency as a function of medium access control (MAC) for large random spreading CDMA random access systems that employ a linear receiver. It is ...

Optimality of Energy Estimates for the Wave Equation with Nonlinear Boundary Velocity Feedbacks
We consider the wave equation damped by a nonlinear boundary velocity feedback q(ut). First we consider the case where q has a linear growth at infinity. We prove that the usual de...

Design and Analysis of Parametric Query Optimization Algorithms
Query optimizers normally compile queries into one optimal plan by assuming complete knowledge of all cost parameters such asselectivity and resourceavailability. The execution of...

Formulations and Reformulations in Integer Programming
Creating good integer programming formulations had, as a basic axiom, the rule “Find formulations with tighter linear relaxations”. This rule, while useful when using unsophist...

A New Characterization of Almost Bent Functions
We study the functions from Fm 2 into Fm 2 for odd m which oppose an optimal resistance to linear cryptanalysis. These functions are called almost bent. It is known that almost ben...
