On a theory of computation and complexity over the real numbers: 𝑁𝑃- completeness, recursive functions and universal machines [PDF]

open access: yesBulletin of the American Mathematical Society, 1989
A model for computation over the reals \({\mathbb{R}}\) (or an arbitrary ordered ring \({\mathcal R})\) is presented. A machine over \({\mathcal R}\) is a digraph with two kinds of nodes: computation (fan-out 1) nodes labelled by polynomial maps \({\mathfrak g}: {\mathcal R}^ n\to {\mathcal R}^ n\), and branching (fan-out 2) nodes labelled by tests ``\(

Real-Time Multi-Target Localization from Unmanned Aerial Vehicles

open access: yesSensors, 2016
In order to improve the reconnaissance efficiency of unmanned aerial vehicle (UAV) electro-optical stabilized imaging systems, a real-time multi-target localization scheme based on an UAV electro-optical stabilized imaging system is proposed.

Laguerre functions on symmetric cones and recursion relations in the real case

open access: yesJournal of Computational and Applied Mathematics, 2007
In this article we derive differential recursion relations for the Laguerre functions on the cone C of positive definite real matrices. The highest weight representations of the group Sp(n,R) play a fundamental role. Each such representation acts on a Hilbert space of holomorphic functions on the tube domain C+ i Sym(n,R).

A Sparse Learning Machine for Real-Time SOC Estimation of Li-ion Batteries

open access: yesIEEE Access, 2020
The state of charge (SOC) estimation of Li-ion batteries has attracted substantial interests in recent years. Kalman Filter has been widely used in real-time battery SOC estimation, however, to build a suitable dynamic battery state-space model is a key ...

Dual-network synergy for inventory forecasting: integrating adaptive feature dynamics and recursive perception correction

open access: yesScientific Reports
Traditional LSTM models in e-commerce inventory forecasting suffer from gradient instability and poor adaptability to rapidly changing market conditions, resulting in suboptimal performance in real-time scenarios.

‘Pulsing’ cities and ‘swarming’ metropolises: A simplified, entropy-based approach to long-term urban development

open access: yesEcological Indicators, 2022
Relocating activities along the fringe, re-designing economic functions, and re-modelling settlement structures across larger regions and broader spatial scales, reflect the inherent shift toward complex metropolitan systems.

Data-Driven Koopman Operator-Based Model Predictive Control with Adaptive Dictionary Learning for Nonlinear Industrial Process Optimization

open access: yesMathematics
Nonlinear model predictive control (NMPC) delivers high tracking accuracy for industrial processes but requires solving a nonlinear program at each sampling instant, limiting its applicability under tight real-time constraints.

Reduction of global interference in functional multidistance near-infrared spectroscopy using empirical mode decomposition and recursive least squares: a Monte Carlo study [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2011
Functional near-infrared spectroscopy (fNIRS) is a sensitive technique that has the potential to detect haemodynamic changes during the performance of specific activation tasks.
