Backward Anticipated Social Optima: Input Constraints and Partial Information

open access: yesMathematics
A class of stochastic linear-quadratic (LQ) dynamic optimization problems involving a large population is investigated in this work. Here, the agents cooperate with each other to minimize certain social costs.

Some optimality principles of sentence pronunciation

open access: yes, 1998
This is a compilation of handouts from 5 classes, Fall 1994, MIT, in which the proposal is advanced that the output of syntax feeds a system that determines how syntactic units are pronounced -- for example, optional and obligatory patterns of deletion ...

A Robbins-Monro type learning algorithm for an entropy maximizing version of stochastic Optimality Theory

open access: yes, 2005
The object of the present work is the analysis of the convergence behaviour of a learning algorithm for grammars belonging to a special version -- the maximum entropy version -- of stochastic Optimality Theory.

Residual Strength Prediction of Chemically Reactive Two‐Phase Nanofluid Flow in a Bingham–Papanastasiou Rheological Theory Using a Morlet‐Based Wavelet Neural Network Approach

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The behavior of nanofluid flow involving a zero‐mass flux condition has received considerable interest because of a realistic scenario. In reality, this condition confines the optimistic accumulation or disappearance of nanoparticles past a sheet, constructing a more physically realistic demonstration through several applications, such as heat

MHD Maxwell Hybrid Nanofluid Transport Featuring Solar Radiation and Thermo‐Diffusive Impacts Over a Permeable Slanted Stretching Sheet

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybrid nanofluids have emerged as next‐generation working fluids for advanced engineering application due to their superior heat transport capability in relation to the conventional nanofluids. Motivated by the rising demand for accurate prediction of transport phenomena under realistic operating situations, the present study examines the ...

An Adaptive RRT* Algorithm for Narrow Passage Path Planning

open access: yesIEEE Access
In recent years, the rapidly exploring random tree star (RRT*) algorithm has continued to attract significant research attention in the field of path planning due to its simple implementation and asymptotic optimality.

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

On the Principle of Optimality for Nonstationary Deterministic Dynamic Programming [PDF]

open access: yes
This note studies a general nonstationary infinite-horizon optimization problem in discrete time. We allow the state space in each period to be an arbitrary set, and the return function in each period to be unbounded.

Working with laws, regularities and singularities in biology: The evolution of mammalian red blood cell size as a case study

open access: yesThe Anatomical Record, EarlyView.
Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (

No Significant Difference in Cost or Outcomes at 1‐Year Minimum Follow‐Up After Arthroscopic Partial Meniscectomy Comparing 1.9 mm Distal Chip‐on‐Tip Needlescope Versus 4 mm Glass Rod Lens Arthroscope: Both Treatments Are Highly Cost‐Effective

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate cost, outcomes, and incremental cost‐effectiveness of arthroscopic partial meniscectomy comparing visualization using a 1.9 mm distal chip‐on‐tip needlescope versus a standard 4 mm glass rod lens arthroscope. Methods We retrospectively reviewed prospectively collected data (from a larger randomized controlled trial) on patients ...
