This book covers code development for structural analysis and includes topics from finite element methods such as modeling and analysis of continuum structures. It explains the concepts showing derivation of necessary equations, relationships, and steps in solving structural analysis problems. It contains worked examples, problem sets, and ample Scilab and Octave codes to teach structural analysis techniques using these softwares. Access to computing facilities has been increasing from time to time, and a typical college student nowadays owns a laptop or has access to a personal computer at home or the college. Besides, there are appropriate software that assist in performing routine and complex matrix operations like matrix multiplication and inversion. The second reason for writing this book is to overcome those difficulties associated with formulating and solving structural analysis problems through programming or coding on a suitable platform step by step and interactively. The book aims to provide concise reading materials explaining the concepts and showing the derivation of necessary equations, relationships and steps in solving structural analysis problems. It also contains worked examples, problem sets and ample Scilab and Octave code to teach structural analysis techniques using MSA/FEM. Scilab and Octave are free and open-source software for scientific computation and visualization. In addition to being free and open-source, they offer excellent platforms for practicing computer-aided structural analysis tasks. Since the syntax for Octave is identical to Matlab, the Octave program codes in this book can be executed in Matlab directly without any modification.

Take a deep dive into the dynamic world of Power BI! Mastering Power BI covers the entire Power BI implementation process. The readers will be able to understand all the concepts covered in this book, from data modeling to creating powerful visualizations. This book begins with concepts and terminology such as the star-schema, dimensions, and facts. It explains multi-table dataset and demonstrates how to load these tables into Power BI. It shows how to load stored data in various formats and create relationships. Readers will also learn more about Data Analysis Expressions (DAX). This book is a must for developers to learn how to extend the usability of Power BI, to explore meaningful and hidden data insights. Throughout the book, you keep on learning about the concepts, techniques, and expert practices on loading and shaping data, visualization design, and security implementation. The second edition of Mastering Power BI book adheres to the first edition in terms of providing the basics of business intelligence and Power BI; however, it introduces new concepts and features in terms of data transformation, data profiling, custom hierarchies, AI visuals, and many more. AI refers to the simulation of human intelligence in machines programmed to think and perform tasks like problem-solving, learning, perception, and decision-making. It encompasses various technologies and techniques, including Machine Learning (ML), Natural Language Processing (NLP), and computer vision, enabling systems to analyze data, recognize patterns, and make informed decisions without explicit programming. This book is for anyone interested in learning how to use Power BI desktop or starting a career in business intelligence and analytics. While it covers all the fundamentals, it is recommended that the reader be familiar with MS Excel and database concepts.
