A Note on the Separability Principle in Economies with Single-Peaked [PDF]

We consider the problem of allocating an infinitely divisible commodity among a group of agents with single-peaked preferences. A rule that has played a central role in the analysis of the problem is the so-called uniform rule.

Uniform bounds in noetherian rings

Inventiones Mathematicae, 1992
The author is interested in various types of uniform behavior for commutative Noetherian rings. This is probably best illustrated by just quoting his two main results. \textit{Uniform Artin-Rees}: Let \(S\) be a Noetherian ring. Let \(N\leq M\) be two finitely generated \(S\)-modules.

Strongly uniform bounds from semi-constructive proofs

Annals of Pure and Applied Logic, 2004
In 2003, the second author obtained metatheorems for the extraction of effective (uniform) bounds from classical, prima facie non-constructive proofs in functional analysis. These metatheorems for the first time cover general classes of structures like arbitrary metric, hyperbolic, CAT(0) and normed linear spaces and guarantee the independence of the ...

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

An Adaptive Human Pilot Model With Reaction Time Delay for Enhanced Adaptive Control in Piloted Systems

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Direction-of-Arrival Estimation Based on Variational Bayesian Inference Under Model Errors

Remote Sensing
The current self-calibration approaches based on sparse Bayesian learning (SBL) demonstrate robust performance under uniform white noise conditions. However, their efficacy degrades significantly in non-uniform noise environments due to acute sensitivity

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Monotonicity and bounds on Bessel functions

Electronic Journal of Differential Equations, 2000
survey my recent results on monotonicity with respect to order of general Bessel functions, which follow from a new identity and lead to best possible uniform bounds.

Strong Limiting Bounds for Maximal Uniform Spacings

The Annals of Probability, 1982
Let $U_1, U_2 \cdots$ be a sequence of independent uniformly distributed random variables on (0, 1) and $M_n$ be the largest spacing induced by $U_1, \cdots, U_n$. We show that $P(M_n \geq (\log n + 2 \log_2n + \log_3n + \cdots + \log_jn)/n \text{i.o.}) = 1$, where $\log_j$ is the $j$ times iterated logarithm, and $j \geq 4$. If $1 = N_1 < N_2 < \cdots
