Nonlinear Hyperbolic Equations and Linear Heat Conduction with Memory

, 2010
The model of a rigid heat conductor with memory is considered. Specifically, in the one-dimensional case, a connection, via Cole-Hopf Transformation, between the linear integro-differential evolution equation which describes heat conduction with memory ...

Farmers' Financial Literacy—Scale Development and Linkages to Accounting Practices and Financial Outcomes

Agribusiness, EarlyView.
ABSTRACT This study investigates the financial literacy (FL) of Swedish farmers, its linkages to farmer characteristics, management accounting practices and farm outcomes by surveying Swedish Farm Accountancy Data Network farmers. Using item response theory, we expand the existing FL measurement specifically to the farming context, assess measurement ...

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency

Agribusiness, EarlyView.
ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

Decomposition solution of nonlinear hyperbolic equations

Mathematical and Computer Modelling, 1990
The application of the decomposition method previously proposed by the author to dissipative wave equations of the form \(u_{tt}- u_{xx}+(\partial /\partial t)(f(u))=g\) is discussed. The initial- boundary value problem \(u_{tt}-u_{xx}+(\partial /\partial t)(u^ 2)=-2 \sin^ 2x\cdot \sin t\cdot \cos t,\) \(u(0,t)=u(\pi,t)=0,\) \(u(x,0)=\sin x,\) \(u_ t(x,

Topological Properties of International Commodity Market: How Uncertainty Affects the Linkages?

Agribusiness, EarlyView.
ABSTRACT The study aims to explore the network topology of the international commodity market by examining the interconnections among 21 commodity futures across various categories, including energy, precious and industrial metals, and agriculture. We analyze the market structure of these commodity futures under both low and high uncertainty conditions

Weighted least-squares approximationsto nonlinear hyperbolic equations

, 2004
Some approximate methods for solving nonlinear hyperbolic equations are presented and analyzed. The methods consist of discretizing with respect to time and solving the resulting hyperbolic equation for fixed time by least-squares finite-element methods.

Food Tastes in the United States: Convergence or Divergence?

Agribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

Dictionary‐based weak‐form training for noise‐robust series hybrid models with multiplicative unknowns

AIChE Journal, EarlyView.
ABSTRACT Hybrid modeling combines first‐principles equations with a data‐driven subcomponent. Training for the data‐driven part is sensitive to measurement noise when training targets are constructed using pointwise time derivatives. Beyond differentiation errors, hybrid models involve solving an inverse problem to estimate the data‐driven term, which ...
