    3084 Words  | 7 Pages

    ABSTRACT A partial differential equation is a differential equation that contain unknown multivariable functions and their partial derivatives while ordinary differential equations contains function of a single variables and their derivatives. Therefore, an ordinary differential equation is a special case of partial differential equation but the behaviour of a solution is quite different. It is much more complicated in the case of partial differential equation because it has more than one independent

  • The Modeling of Salt Water Intrusion

    1524 Words  | 4 Pages

    The Modeling of Salt Water Intrusion What is Salt Water Intrusion? Salt water intrusion, or encroachment, is defined by Freeze and Cherry (1979) as the migration of salt water into fresh water aquifers under the influence of groundwater development. Salt water intrusion becomes a problem in coastal areas where fresh water aquifers are hydraulically connected with seawater. When large amounts of fresh water are withdrawn from these aquifers, hydraulic gradients encourage the flow of seawater

    Introduction Nodal methods were first introduced and developed to solve neutron diffusion equations in 1970’s [2]. The success of Nodal methods in the field of neutronics was stimulated into the heat flow and fluid flow problems in 1980 [3]. The Nodal Integral Method scheme is developed by approximately satisfying the governing differential equations on finite size brick-like elements. These differential equations are obtained by discretizing the space of independent variables [4]. In the early development

    Having more than one mathematician in a family is not unheard of. There have been many father-son and father-daughter duos in the history of mathematics, e.g. Theon and Hypatia, Farcas Bolyai(1775-1856) and Janos Bolyai(1802-1860), George David Birkhoff(1884-1944) and Garrent Birkhoff, Emil and Michael Artin, Elie and Henri Cartan, etc. The Riccati family in Italy managed to produce three mathematicians, but the their contributions to mathematics do not compare to that of all eight of the Bernoulli

To make coinciding with the equilibrium position, the arbitrary zero of potential must be shifted to eliminate V_0. Consequently the term (∂V/〖∂q〗_i )

    Jacob Bernoulli was born on the 27th of December, 1654, to Niklaus and Margarethe Bernoulli, in Basel, Switzerland. He initially abided by his father’s wishes and studied theology, eventually joining the ministry, but also chose to study both mathematics and astronomy on the side. From the ages of 22 to 28, he traveled throughout Europe, learning about the most recent advances in mathematics and the natural sciences, including recent discoveries by Boyle and Hooke. It was through extended communication

    This paper presents the study of non-linear dynamic of cardiac excitation based on Luo Rudy Phase I (LR-I) model towards numerical solutions of ordinary differential equations (ODEs) responsible for cardiac excitation on FPGA. As computational modeling needs vast of simulation time, a real-time hardware implementation using FPGA could be the solution as it provides high configurability and performance. For rapid prototyping, the MATLAB Simulink offers a link with the FPGA which is an HDL Coder that

    Chaos Theory Explained “Traditionally, scientists have looked for the simplest view of the world around us. Now, mathematics and computer powers have produced a theory that helps researchers to understand the complexities of nature. The theory of chaos touches all disciplines.” -Ian Percival, The Essence of Chaos Part I: The Basics of Chaos.

She is showing the same disinterest in what we are doing, that I show to my Differential Equations professor. This 8 year old girl is thinking about snack time, or about what she is going to do at recess that day. The things that are important and surround her in her life. Age changes our boredom, and what we focus on. I think most of that

    Calculus is defined as, "The branch of mathematics that deals with the finding and properties of derivatives and integrals of functions, by methods originally based on the summation of infinitesimal differences. The two main types are differential calculus and integral calculus." (Oxford Dictionary). Contrary to any other type of math, calculus allowed Newton and other scientists to process the different motions and dynamic changes in world, such as the orbit of planets in space. Newton first became

    Approximating Solutions for Differential Equations A differential equation is defined as an equation which relates an unknown function to one or more derivatives. When solved and transformed into its original equation in the form f(x), an exact value can be found at any given point. While some differential equations can be solved, it is important to realize that very few differential equations that come from "real world" problems can be solved explicitly, and often it is necessary to resort to numerical

  • The Evolution of Differential Calculus

    Differential calculus is a subfield of Calculus that focuses on derivates, which are used to describe rates of change that are not constants. The term ‘differential’ comes from the process known as differentiation, which is the process of finding the derivative of a curve. Differential calculus is a major topic covered in calculus. According to Interactive Mathematics, “We use the derivative to determine the maximum and minimum values of particular functions (e.g. cost, strength, amount of material
