The χ-Ramsey problem for triangle-free graphs [PDF]

open access: yes, 2021
In 1967, Erdős asked for the greatest chromatic number, f(n), amongst all n-vertex, triangle-free graphs. An observation of Erdős and Hajnal together with Shearer's classical upper bound for the off-diagonal Ramsey number R(3,t) shows that f(n) is at ...

The boundedness of classical operators on variable L-p spaces [PDF]

open access: yes, 2006
We show that many classical operators in harmonic analysis ---such as maximal operators, singular integrals, commutators and fractional integrals--- are bounded on the variable Lebesgue space $L^{p(\cdot)}$ whenever the Hardy-Littlewood maximal operator ...

Geometric effects on T-breaking in p+ip and d+id superconductors

open access: yes, 2003
Superconducting order parameters that change phase around the Fermi surface modify Josephson tunneling behavior, as in the phase-sensitive measurements that confirmed $d$ order in the cuprates.

The X-Ramsey Problem for Triangle-Free Graphs [PDF]

open access: yes, 2022
In 1967, Erd\H os asked for the greatest chromatic number, f(n), amongst all n-vertex, triangle-free graphs. An observation of Erd\H os and Hajnal together with Shearer's classical upper bound for the off-diagonal Ramsey number R(3, t) shows that f(n ...

Online Assignment Algorithms for Dynamic Bipartite Graphs [PDF]

open access: yes, 2011
This paper analyzes the problem of assigning weights to edges incrementally in a dynamic complete bipartite graph consisting of producer and consumer nodes. The objective is to minimize the overall cost while satisfying certain constraints.

Investigation of AASHTOWare Pavement ME Design/DARWin-MEPerformance Prediction Models for Iowa Pavement Analysis and Design [PDF]

open access: yes, 2015
The Mechanistic-Empirical Pavement Design Guide (MEPDG) was developed under National Cooperative Highway Research Program (NCHRP) Project 1-37A as a novel mechanistic-empirical procedure for the analysis and design of pavements.

Estimation of effective hydrologic properties of soils from observations of vegetation density [PDF]

open access: yes, 1980
A one-dimensional model of the annual water balance is reviewed. Improvements are made in the method of calculating the bare soil component of evaporation, and in the way surface retention is handled.

Optimality and duality for a class of nonsmooth fractional multiobjective optimization problems (Nonlinear Analysis and Convex Analysis) [PDF]

open access: yes, 2018
In this paper, we establish necessary optimality conditions for (weakly) efficient solutions of a nonsmooth fractional multiobjective optimization problem with inequality and equality constraints by employing some advanced tools of variational analysis ...
