Flexible covariate-adjusted exact tests of randomized treatment effects with application to a trial of HIV education

open access: yes, 2013
The primary goal of randomized trials is to compare the effects of different interventions on some outcome of interest. In addition to the treatment assignment and outcome, data on baseline covariates, such as demographic characteristics or biomarker ...

Selection usmg an Auxiliary Measurement

open access: yesJapanese Journal of Breeding, 1962
The condition for superior index selection using I=X1-bX2 to direct selection was theoretically confirmed. When 1) h12/h22>r2G and 2) phenotypic regression of X2 on X1> genotypic regression of X2 on X1 are satisfied, a constant b lies between limits ...

A Semantic Principle of Auxiliary Selection in Dutch

open access: yesNatural Language & Linguistic Theory, 1997
We propose that the choice between the auxiliaries hebben ‘have’ and zijn ‘be’ in Dutch is determined by a particular semantic feature of verbs. In particular we propose a feature of meaning [IEPS] for ‘inferable eventual position or state’ that characterizes whether the action denoted by the verb allows us to determine the eventual position or state ...

A constrained multi-objective optimization algorithm based on dynamic auxiliary tasks for UAV path planning

open access: yesResults in Engineering
While numerous constrained multi-objective optimization algorithms have been proposed, effectively balancing convergence, diversity, and feasibility remains challenging in the context of unmanned aerial vehicle (UAV) path planning within complex ...

Rellich-type Discrete Compactness for Some Discontinuous Galerkin FEM [PDF]

open access: yes
We deduce discrete compactness of Rellich type for some discontinuous Galerkin finite element methods (DGFEM) including hybrid ones, under fairly general settings on the triangulations and the finite element spaces.

Hydrogen-Enabled Power Systems: Technologies’ Options Overview and Effect on the Balance of Plant

open access: yesHydrogen
Hydrogen-based Power Systems (H2PSs) are gaining accelerating momentum globally to reduce energy costs and dependency on fossil fuels. A H2PS typically comprises three main parts: hydrogen production, storage, and power generation, called packages.

A Constrained Multi-Objective Optimization Algorithm with a Population State Discrimination Model

open access: yesMathematics
The solution to constrained multi-objective optimization problems (CMOPs) requires optimizing the objective functions while satisfying the constraint conditions. To effectively address CMOPs, algorithms must balance objectives and constraints.
