ON SOME MATHEMATICAL ECONOMIC MODELS SOLVED BY THE METHOD OF LAGRANGE MULTIPLIERS [PDF]
Annals of the University of Petrosani: Economics, 2016 Many of the economic and technical problems can be mathematically modelled and the mathematical model leads to solving some nonlinear equations or finding of some extreme values.

On the modal equations of large amplitude flexural vibration of beams, plates, rings and shells
, 1973 In a simple and straight forward manner the modal equations applicable for the large amplitude flexural vibrations of plates and shells are obtained by the Lagrange's method. These equations can easily be specialised to obtain the corresponding equations

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors
Advanced Electronic Materials, EarlyView.Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,

A study on dynamic response of functionally graded sandwich beams under different dynamic loadings [PDF]
MATEC Web of Conferences, 2018 In this research, free and forced vibration of functionally graded sandwich beams is considered using Timoshenko beam theory which takes into account the significant effects of transverse shear deformation and rotary inertia.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Rice is the main staple food for more than half of the world's population and the income from rice is an essential source for livelihoods of millions of households. We examine whether direct seed in rice production is an adaptation of rice farmers to rainfall changes and farm labor scarcity.

Metoda Krakowianowa w Rozwiazywaniu Równań Ruchu Układów Dynamicznych
Engineering Transactions, 1963 This paper is devoted to the application of the Cracovian calculus lo the integration of Lagrange's equations of motion. The Cracovian calculus gives considerable simplicity and lucidity to familiar arguments and schemes.

Poincaré’s Equations for Cosserat Media: Application to Shells
, 2016 International audienceIn 1901 Henri Poincaré discovered a new set of equations for mechanics. These equations are a generalization of Lagrange's equations for a system whose configuration space is a Lie group which is not necessarily commutative.

Agribusiness, EarlyView.Abstract The vegetable market experiences significant price fluctuations due to the complex interplay of trend, cyclical, seasonal, and irregular factors. This study takes Korean green onions as an example and employs the Christiano–Fitzgerald filter and the CensusX‐13 seasonal adjustment methods to decompose its price into four components: trend ...

Agribusiness, EarlyView.ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...
