Extracting the maximum energy from solar panels

Nfaoui, Mohamed; El-Hami, Khalil - In: Energy Reports 4 (2018), pp. 536-545

The performance of solar systems to convert solar radiation depends on its inclination angle to the horizontal plane … used to estimate the total solar radiation on a tilted panel surface with any inclination. The implementation developed to …

On oscillations of the geometric Brownian motion with time delayed drift

Küchler, Uwe; Gushchin, Alexander A. - 2003

The geometric Brownian motion is the solution of a linear stochastic differential equation in the Itô-sense. If one adds to the drift term a possible nonlinear time delayed term and starts with a nonnegative initial process then the process generated in this way, may hit zero and may oscillate...

Ecuaciones diferenciales y en diferencias aplicadas a los conceptos económicos y financieros

Tenorio Villalón, Ángel F.; Martín Caraballo, Ana M.; … - In: Revista de Métodos Cuantitativos para la Economía y … 16 (2013), pp. 165-199

This paper deals with the use of differential equations and finite difference methods for solving several problems in the field of Economics and Business Administration. Economics usually needs to study the evolution of the values which are taken by a given variable in different moments. If the...

The dynamics of terrorist organizations

Hausken, Kjell - In: Operations Research Perspectives 6 (2019), pp. 1-14

Terrorist organizations are most often comprised of ideologues, criminal mercenaries, and captive participants. Ideologues provide political purpose and direction and have a strong group commitment. However, every organization needs money to survive. For terrorist organizations this comes...

A Remark on the Form of Accumulation Functions in Economic Growth Models

Yetkiner, I. Hakan - 2012

This study is a short note designed to underline the importance of using the theoretically required form of accumulation functions. It is now a common knowledge that a growth model must rely on non-diminishing returns to a factor of production in order to generate endogenous growth. In Lucas...

Convexity, Differential Equations, and Games

Flåm, Sjur Didrik - 2002

Theoretical and experimental studies of noncooperative games increasingly recognize Nash equilibrium as a limiting outcome of players' repeated interaction. This note, while sharing that view, illustrates and advocates combined use of convex optimization and differential equations, the purpose...

A critique of the Richardson equations

Beckmann, Klaus; Gattke, Susan; Lechner, Anja; Reimer, … - 2016

We review, and extend, one of the classic dynamic models of conflict in economics by Richardson (1919) and Boulding (1962). Restrictions on parameters are relaxed to account for alliances and for peace-keeping, yielding new dynamic patterns of conflict. In addition, we explore an incrementalist...

A Bitcoin price prediction model assuming oscillatory growth and lengthening cycles

Wang, Guizhou; Hausken, Kjell - In: Cogent Economics & Finance 10 (2022) 1, pp. 1-29

This article's motivation is to understand the volatile Bitcoin price increase. The objective is to develop price estimation methods. The methodology is to present five differential equation models estimated against the 23 July 2010-21 June 2021 Bitcoin data. The findings are that Gompertz...
