Predicting EU Emissions Allowance Prices Using Macroeconomic Indicators and Hybrid AI Models

Journal of Forecasting, EarlyView.
ABSTRACT Predicting carbon allowance prices has grown more crucial in relation to carbon market regulation, financial strategy, and environmental policy development. This study examines a hybrid forecasting system that combines deep learning with ensemble machine learning models to forecast the price fluctuations of EU Emissions Allowance (EUAs) within

Collocation and mass matrix in least-squares isogeometric analysis

Computer-Aided Design
In this paper, we conduct a systematic numerical analysis of the spectral properties of the collocation and mass matrices in the isogeometric least-squares collocation method (IGA-L), for the approximation of the Poisson problem with homogeneous Dirichlet boundary conditions.

Towards climate‐conscious corporate restructuring: A comparative exploration of English and Bhutanese legal frameworks

International Insolvency Review, EarlyView.
Abstract This paper conducts a comparative legal analysis of corporate restructuring frameworks in England and Bhutan, examining their capacity to integrate climate variability considerations and promote sustainable business practices. It discusses the procedural mechanisms for restructuring financially distressed enterprises available under the law of

Enhanced geoid modelling in local geodetic networks: Comparative analysis of Least Squares Collocation techniques

Nova Geodesia
The geoid is an equipotential surface of the Earth’s gravity field that closely approximates mean sea level in a least-squares sense. Meanwhile, this study aims to enhance local geoid modeling by comparing the Stationary (SLSC) and Non-Stationary Least ...

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

用最小二乘配置法构建局部重力场模型

Dizhen xuebao, 2020
基于非均匀分布的陆地重力观测数据，重构局部重力场模型是区域重力资料处理与解释的重要环节。本文对比了多种局部重力场建模方法，并以EGM2008模型提供的自由空气重力异常模型重采样数据进行测试，综合比较了不同噪声条件下不同建模方法的实际效果。结果表明：在不同噪声水平下，优选出适合重力位场问题的协方差函数后，最小二乘配置法的建模效果优于其它方法。

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...
