Basic Mathematical Concepts

As in the development of other areas of engineering, mathematics has played an important role in the development of the safety and reliability fields in the oil and gas industry too. The history of mathematics may be traced back to the development of our currently used number symbols, often referred to as the Hindu-Arabic numeral system in the published literature [1]. Among the early evidence of the use of these numerals are the notches found on stone columns erected around 250 bc by the Scythian Emperor of India named Asoka [1]. 

Laplace transforms, often used in the area of reliability to find solutions to first-order differential equations, were developed by the French mathematician named Pierre-Simon Laplace (1749-1827). Additional information on the history of mathematics and probability is available in References 1 and 2. This chapter presents basic mathematical concepts considered useful to understand subsequent chapters of this book.

There is a large body of literature on FTIR spectroscopy including, for example, Bracewell (1965), Horlick (1968), Bell (1972), Griffiths (1975, 1983), Ferraro and Basile (1978), Koenig (1981), Griffiths and de Haseth (1986), Perkins (1986, 1987), Mackenzie (1988). Cameron and Moffatt (1984), and Gillette et al. (1985) have explained the basic mathematical concepts of deconvolution, derivation and smoothing in FTIR spectroscopy. 

Although some of the physical ideas of classical mechanics is older than written history, the basic mathematical concepts are based on Isaac Newton s axioms published in his book Philosophiae Naturalis Principia Mathematica or principia that appeared in 1687. Translating from the original Latin, the three axioms or the laws of motion can be approximately stated [7] (p. 13) ... 

Students are required to acquire ten core competencies and undertake a number of specified specialist/optional units of competence. Core units of competence are common to all sectors in the food processing industry, e.g. dairy processing, flour and stock feed milling, general foods, pet food, and pharmaceutical manufacturing. Such core competencies include application of basic mathematical concepts, basic quality assurance practices, communication in the workplace, the collection, presentation and application of workplace information, and the implementation of occupational health and safety principles and procedures. 

The knowledge and use of basic mathematical concepts and skills is a necessary aspect of scientific study. Science depends on data and the manipulation of data requires knowledge of mathematics. Scientists often use basic algebra to solve scientific problems and design experiments. For example, the substitution of variables is a common strategy in experiment design. Also, the ability to determine the equation of a curve is valuable in data manipulation, experimentation, and prediction. 

The value approach allows to solve one of the most important qnestions in the theory of optimal control, namely, to make chemically meaningful choice of the most effective control parameters. Simultaneously, the physical-chemical, vo/ug-based understanding of basic mathematical concepts of the Maximum Principle makes possible to determine their initial magnitudes. This greatly simplifies the computational procedures and makes them effective. 

The basic mathematical concepts for representation and evaluation of molecular structures Molecular graphs, substructures, restrictions, reactions, structure generation, molecular descriptors and the statistical learning methods that play a central role in the applications. 

Solids, as black body radiators, emit light that can be characterized by its radiated power, spectral profile, and photon flux. These concepts are described in this chapter. The spectroscopy of solids is a vast field encompassing many volumes and thus the scope of this chapter is constrained to the basic mathematical concepts and relationships related to the spectroscopy of solids. For additional discussion on the interaction of light with solids see Blaker (1970), Ditchburn (1965), Fogiel (1981), Goodman (1985), Jenkins and White (1957), Johnson and Pedersen (1986), or Mach (1926). 

This section introduces the basic mathematics of linear vector spaces as an alternative conceptual scheme for quantum-mechanical wave functions. The concept of vector spaces was developed before quantum mechanics, but Dirac applied it to wave functions and introduced a particularly useful and widely accepted notation. Much of the literature on quantum mechanics uses Dirac s ideas and notation.

In this chapter, we present the basic matrix mathematics that is required for understanding the methods introduced later in the book. In line with the philosophy that all concepts are immediately implemented in Matlab and/or Excel, this will be done here as well. This way, Chapter 2 not only revises the basic mathematics, it also serves as a very short introduction to the Matlab and Excel languages. It is not meant to be a manual on Matlab or Excel the reader will need to refer to more specialised texts and proper manuals. Several more advanced features of both languages are not covered at this introductory stage but will be explained as they emerge in later chapters. 

In this chapter we will deal with those parts of acoustic wave theory which are relevant to chemists in the understanding of how they may best apply ultrasound to their reaction system. Such discussions tvill of necessity involve the use of mathematical concepts to support the qualitative arguments. Wherever possible the rigour necessary for the derivation of the basic mathematical equations has been kept to a minimum within the text. An expanded treatment of some of the derivations of key equations is provided in the appendices. For those readers who would like to delve more deeply into the physics and mathematics of acoustic cavitation numerous texts are available dealing with bubble dynamics [1-3]. Others have combined an extensive treatment of theory with the chemical and physical effects of cavitation [4-6]. 

To a significant extent, the theoretical basis of modern communication theory arose from the work of Claude Shannon at Bell Labs. [80]. In these seminal works, the concept of the information entropy associated with an arbitrary signal arose. In 1981, Watanabe realised the close association between entropy minimization and pattern recognition [81]. An association between entropy minimization and the principle of simplicity is also recognized [82]. The basic mathematical form of signal... 

Physical chemistry and physics may be different fields but they have some important features in common they are abstract they both use mathematics they overlap in some content areas (such as thermodynamics and quantum mechanics). To a large extent, science and physics educators started research on basic physics concepts that also are used in physical chemistry. Consequently, physical chemistry education research owns much to the work that has been done in physics education and has much in common with it. For example, they share some of the research methodology and an interest in studying the relationship between the physical description of phenomena and its mathematics description in the learner s mind. 

A few basic physical and mathematical concepts are essential to the study of kinetics, and several of these concepts are introduced below using a mathematical language suited to a discussion of kinetics. 

The Quantitative section measures your general understanding of basic high school mathematical concepts. You will not need to know any advanced mathematics. This test is a simple measure of your availability to reason clearly in a quantitative setting. Therefore, you will not be allowed to use a calculator on this exam. Many of the questions are posed as word problems relating to real-life situations. The quantitative information is given in the text of the questions, in tables and graphs, or in coordinate systems. 

This section is a review of basic mathematical skills. For success on the GRE, it is important to master these skills. Because the GRE measures your ability to reason rather than calculate, most of this section is devoted to concepts rather than arithmetic drills. Be sure to review all the topics before moving on to the algebra section.
