Solving PDEs in Python: The FEniCS Tutorial I (Simula SpringerBriefs on Computing)
This book offers a concise and gentle introduction to finite element programming in Python based on the popular FEniCS software library. Using a series of examples, including the Poisson equation, the equations of linear elasticity, the incompressible Navier–Stokes equations, and systems of nonlinear advection–diffusion–reaction equations, it guides readers through the essential steps to quickly solving a PDE in FEniCS, such as how to define a finite variational problem, how to set boundary conditions, how to solve linear and nonlinear systems, and how to visualize solutions and structure finite element Python programs.

Mathematics for the Physical Sciences
Introduction to and use of complex analysis and algebraic techniques to understand the solution of boundary value problems. Physics examples serve to introduce the fundamental partial differential equations and “special functions” of mathematical physics. A thorough analysis of Green’s functions leads to a discussion of integral equations. Supplementary topics include dispersion relations and rational function approximation.

Power BI Step-by-Step Part 2: Connecting to Data Sources: Power BI Mastery through hands-on Tutorials (Power BI Step by Step)

Self-Service Business Intelligence


Power BI enables business users to interact with corporate information and to extract the reports and intel they need. Power BI allows users to access reports and dashboards using familiar tools and devices. Self-service BI has never been so user-friendly!


The Microsoft Power BI Step-by-Step series will show you how to create compelling visualizations and reports which provide deep insights into your data.


This first book in the series is designed to get you up and running with the three main components of Power BI:


Power BI Desktop


the Power BI Service


and Power BI Mobile Apps.


What you will Learn from the Power BI Step-by-Step Series


You will learn how to connect to a wide variety of data sources, using both Power BI Desktop, and the Power BI Service.


You will be able to use the Query Editor to transform and morph data into the right format for your reporting purposes.


You will be able to perform complex data modelling operations using relationships, calculated columns, measures, and DAX expressions.


You will learn how to share dashboards and reports, with colleagues, business partners and potential clients; and how to use Power BI’s sophisticated security features to control the exact content your audience is able to view.


In short, the Power BI Step-by-Step series will equip you with all the skills you need to start using Power BI with confidence.


Part 2: Connecting to Data Sources


The aim of this second book in the series is explore Power BI data connections. However, these tutorials will also provide some further practice on report creation.

Control Theory Tutorial: Basic Concepts Illustrated by Software Examples (SpringerBriefs in Applied Sciences and Technology)
This open access Brief introduces the basic principles of control theory in a concise self-study guide. It complements the classic texts by emphasizing the simple conceptual unity of the subject. A novice can quickly see how and why the different parts fit together. The concepts build slowly and naturally one after another, until the reader soon has a view of the whole. Each concept is illustrated by detailed examples and graphics. The full software code for each example is available, providing the basis for experimenting with various assumptions, learning how to write programs for control analysis, and setting the stage for future research projects. The topics focus on robustness, design trade-offs, and optimality. Most of the book develops classical linear theory. The last part of the book considers robustness with respect to nonlinearity and explicitly nonlinear extensions, as well as advanced topics such as adaptive control and model predictive control. New students, as well as scientists from other backgrounds who want a concise and easy-to-grasp coverage of control theory, will benefit from the emphasis on concepts and broad understanding of the various approaches.

The Cellular Automaton Interpretation of Quantum Mechanics (Fundamental Theories of Physics)

This book presents the deterministic view of quantum mechanics developed by Nobel Laureate Gerard 't Hooft.

Dissatisfied with the uncomfortable gaps in the way conventional quantum mechanics meshes with the classical world, 't Hooft has revived the old hidden variable ideas, but now in a much more systematic way than usual. In this, quantum mechanics is viewed as a tool rather than a theory.

The author gives examples of models that are classical in essence, but can be analysed by the use of quantum techniques, and argues that even the Standard Model, together with gravitational interactions, might be viewed as a quantum mechanical approach to analysing a system that could be classical at its core. He shows how this approach, even though it is based on hidden variables, can be plausibly reconciled with Bell's theorem, and how the usual objections voiced against the idea of ‘superdeterminism' can be overcome, at least in principle.

This framework elegantly explains - and automatically cures - the problems of the wave function collapse and the measurement problem. Even the existence of an “arrow of time" can perhaps be explained in a more elegant way than usual. As well as reviewing the author’s earlier work in the field, the book also contains many new observations and calculations. It provides stimulating reading for all physicists working on the foundations of quantum theory.

Orthogonal Functions: The Many Uses of
Orthogonal functions are clever tools that unlock many mathematical puzzles. Once you've seen this done and understand how they work, you will find many more useful applications. This remarkable area of applied mathematics supports a wide range of technologies, ranging from CAT scans to satellite pictures from space to unraveling the sounds of the deep. Join me on a tour of this fascinating topic in which we will explore data sampling and approximation in both temporal and spatial dimensions.
