Mathematical Markup Language (MathML) is an application of XML for representing mathematical symbols and formulae, aimed at integrating them into World Wide Web documents. It is a recommendation of the W3C math working group. The specification of version 1.01 of the format was released in July 1999 and version 2.0 appeared in February 2001. In October 2003, the second edition of MathML Version 2.0 was published as the final release by the W3C math working group. MathML was originally designed before the finalization of XML namespaces.

An Application of Structural Equation Modeling in Evaluating Accident/Injury Occurrences in Underground Coal Mines
Introduction
 The purpose of this presentation is to show how Structural Equation Modeling (SEM) can be applied to real life problem solving.
Stages in SEM
• Stage 1: Developing a Theoretically Based
Model
• Stage 2: Constructing a Path Diagram of Causal Relationships
– Elements of a Path Diagram
– Examples of Path Diagrams ....etc

If the secondary coil is attached to a load that allows current to flow, electrical power is transmitted from the primary circuit to the secondary circuit.Ideally,the transformer is perfectly efficient; all the incoming energy is transformed from the primary circuit to the magnetic field and into the secondary circuit. If this condition is met, the incoming electric power must equal the outgoing power.
Pincoming = IPVP = Poutgoing = ISVS

giving the ideal transformer equation

Mathematical Markup Language (MathML)

It aims at integrating mathematical formulae into World Wide Web documents and is an application of XML for unfolding mathematical notation and capturing both its structure and content. It is a recommendation of the W3C math working group. MathML deals not only with the presentation but also the meaning of formula components (the latter part of MathML is known as Content MathML). The user decides on how the content is communicated as the meaning of the equati ....etc

Introduction

Laplace's equation
Laplace's equation is a partial differential equation. Partial differential equations (PDE) are a type of differential equation, i.e., a relation involving an unknown function (or functions) of several independent variables and their partial derivatives with respect to those variables. Partial differential equations are used to formulate, and thus aid the solution of, problems involving functions of several variable ....etc
