"The aim of this research is to analyze the implementation of Sustainable Competitive Advantage (SCA) as a strategy taken by PT Garuda Indonesia in facing the commercial flight business competition in Indonesia. This research adopted Boston Consulting Group (BCG) matrix theory and the SCA approach to identify the competitive position of Garuda among its competitors in the airline industry and to analyze the component of competitors, consisting familiarity towards its own product, familiarity towards competitors, familiarity towards the competitors’ product and the component of competition techniques comprising cost advantage, product differentiation, market focus, pioneering products and market synergy. The result of this research shows that competitive position of Garuda in the airline industry in Indonesia is in the star quadrant, possessing the growth of long run opportunities. The strategies that could be adopted were forward integration, backward integration, horizontal integration, market penetration, market development and product development. Therefore it could be concluded that the SCA concept could be adopted as the marketing strategy of Garuda. The optimal adoption of the SCA concept as the marketing strategy that possessed the sustainable competition requires mending and improvement of such strategies as market synergy, human resources development and the market extension."

"Biased towards functional methods, this work presents a polynomial approach to Linear Algebra. Using the shift operator as a central object it makes linear algebra a suitable introduction to other areas of mathematics, particularly operator theory."

"The main purpose of Linear algebra and linear models is to provide a rigorous introduction to the basic aspects of the theory of linear estimation and hypothesis testing. The necessary prerequisites in matrices, multivariate normal distribution, and distributions of quadratic forms are developed along the way. For this third edition, the material has been reorganised to develop the linear algebra in the first six chapters. Other key features include, coverage of topics such as rank additivity, inequalities for eigenvalues and singular values, a new chapter on linear mixed models, over seventy additional problems on rank : the matrix rank is an important and rich topic with connections to many aspects of linear algebra such as generalized inverses, idempotent matrices and partitioned matrices."

"This textbook on linear algebra includes the key topics of the usual topics, such as complex vector spaces, complex inner products, the Spectral theorem for normal operators, dual spaces, the minimal polynomial, the Jordan canonical form, and the rational canonical form, are covered, along with a chapter on determinants at the end of the book. In addition, there is material throughout the text on linear differential equations and how it integrates with all of the important concepts in linear algebra.This book has several distinguishing features that set it apart from other linear algebra texts. For example, Gaussian elimination is used as the key tool in getting at eigenvalues, it takes an essentially determinant-free approach to linear algebra, and systems of linear differential equations are used as frequent motivation for the reader.

"Abstract. The aim of this research is to analyze the implementation of Sustainable Competitive Advantage (SCA) as a strategy taken by PT Garuda Indonesia in facing the commercial flight business competition in Indonesia. This research adopted Boston Consulting Group (BCG) matrix theory and the SCA approach to identify the competitive position of Garuda among its competitors in the airline industry and to analyze the component of competitors, consisting familiarity towards its own product, familiarity towards competitors, familiarity towards the competitors? product and the component of competition techniques comprising cost advantage, product differentiation, market focus, pioneering products and market synergy.The result of this research shows that competitive position of Garuda in the airline industry in Indonesia is in the star quadrant, possessing the growth of long run opportunities. The strategies that could be adopted were forward integration, backward integration, horizontal integration, market penetration, market development and product development. Therefore it could be concluded that the SCA concept could be adopted as the marketing strategy of Garuda. The optimal adoption of the SCA concept as the marketing strategy that possessed the sustainable competition requires mending and improvement of such strategies as market synergy, human resources development and the market extension."

"This book offers a refreshingly concise text suitable for a standard course in linear algebra. The focus throughout is rooted in the mathematical fundamentals, but the text also investigates a number of interesting applications, including a section on computer graphics, a chapter on numerical methods, and many exercises and examples using MATLAB. Meanwhile, many visuals and problems (a complete solutions manual is available to instructors) are included to enhance and reinforce understanding throughout the book."

"Starting with matrices over the integers, part 1 of this book provides a measured introduction to such groups, two finitely generated abelian groups are isomorphic if and only if their invariant factor sequences are identical. The analogous theory of matrix similarity over a field is then developed in part 2 starting with matrices having polynomial entries, two matrices over a field are similar if and only if their rational canonical forms are equal. Under certain conditions each matrix is similar to a diagonal or nearly diagonal matrix, namely its Jordan form."

"The book is intended to be used either as a self-study guide, a textbook for a course in advanced linear algebra, or as a reference book. It is also designed to prepare a student for the linear algebra portion of prelim exams or PhD qualifying exams. The volume is self-contained to the extent that it does not assume any previous formal knowledge of linear algebra, though the reader is assumed to have been exposed, at least informally, to some of the basic ideas and techniques, such as manipulation of small matrices and the solution of small systems of linear equations over the real numbers. More importantly, it assumes a seriousness of purpose, considerable motivation, and a modicum of mathematical sophistication on the part of the reader. In the latest edition, new major theorems have been added, as well as many new examples. There are over 130 additional exercises and many of the previous exercises have been revised or rewritten. In addition, a large number of additional biographical notes and thumbnail portraits of mathematicians have been included."
