Development of spatially variant photonic crystals to control light in the near-infrared spectrum
Scientific Reports, 2022 Spatially Variant Photonic Crystals (SVPCs) have shown the ability to control the propagation and direction of light in the near-infrared spectrum. Using a novel approach for simplified modeling and fabrication techniques, we designed unique, spatially ...

Optimal growth and Pareto optimality [PDF]
Journal of Mathematical Economics, 1991 Abstract The purpose of this paper is to show that in a stationary intertemporal economy where agents have recursive utilities every Pareto optimum is a solution of a generalized McKenzie problem. An ‘abstract’ state space is introduced as the space of couples of capital stock and utilities that can be reached by n −1 agents from that capital stock.

An Optimal Preparation for Studying Optimization [PDF]
Neuron, 2000 Imagine a fly navigating through a forest at 2 m/s. In order to correct for the effects of the wind and other flight instabilities, the fly must continually estimate its heading direction if only to avoid running into a tree or inadvertently flying in circles. Given the striking prominence of eyes on a fly's body, it is not surprising that vision plays

The Number of Steps Needed for Nonconvex Optimization of a Deep Learning Optimizer is a Rational Function of Batch Size [PDF]
arXiv, 2021 Recently, convergence as well as convergence rate analyses of deep learning optimizers for nonconvex optimization have been widely studied. Meanwhile, numerical evaluations for the optimizers have precisely clarified the relationship between batch size and the number of steps needed for training deep neural networks. The main contribution of this paper

A novel swarm intelligence optimization approach: sparrow search algorithm
, 2020 In this paper, a novel swarm optimization approach, namely sparrow search algorithm (SSA), is proposed inspired by the group wisdom, foraging and anti-predation behaviours of sparrows.

Scientific Reports, 2023 Re-design of microwave passive components for the assumed operating frequencies or substrate parameters is an important yet a tedious process. It requires simultaneous tuning of relevant circuit variables, often over broad ranges thereof, to ensure ...

A constraint programming approach to the hospitals/residents problem [PDF]
, 2007 An instance I of the Hospitals/Residents problem (HR) involves a set of residents (graduating medical students) and a set of hospitals, where each hospital has a given capacity.

IMF Economic Review, 2009 The paper analyzes optimal policy in a simple small open economy model with price setting frictions. In particular, the paper studies the optimal response of the nominal exchange rate following a terms-of-trade shock. The paper departs from the New Keynesian (NK) literature in that it explicitly models internationally traded commodities as intermediate
