A practical guide for leading others with wisdom, integrity, and humanity This book argues that great leadership requires wisdom. Rather than a formulaic managerial approach to leadership, Lead with Wisdom presents the case for leadership based on our shared humanity and the stories that unite us. What emerges is a model of leadership based on learning to read key patterns of human experience: the way language shapes our reality, how we form new meaning through conversation, how relationships determine influence and how we deal with uncertainty. It presents readers with the tools and illustrated examples to implement the four arts of leading wisely: how to draw out and create a new story in the organization, how to find and leverage the brilliance of people, how to speak with promise to restore meaning and hope, and how to show grace in dealing with the most demanding people and circumstances. Offers a leadership approach rooted in our shared humanity and the stories which unite and define us Ideal for corporate leaders, middle managers, administrators, and anyone else with management responsibilities Written by a popular speaker on leadership and the author of Arts of the Wise Leader, with personal CEO experience and a PhD in the history of ideas Structured as one key idea per page or double page spread with funky line drawings supporting the concepts and skills For anyone who wants to lead with wisdom, integrity, and humanity, Lead with Wisdom offers a welcome alternative to traditionally robotic and formulaic leadership strategies.

Inspire and empower your team to collaborate across any boundary Think One Team, 2nd Edition: The Revolutionary 90 Day Plan that Engages Employees, Connects Silos and Transforms Organisations weaves a fascinating and entertaining tale that reveals how a simple change in approach can free your organisation of silo-based thinking, and empower your team to act as a single unit. This imaginative, yet practical text is fully revised and updated, and has been specifically designed to guide you in creating and sustaining the agile, teamwork-focused environment that is essential to thriving in a rapidly changing world. Throughout this enlightening resource, you will explore the five practices that define the difference between fragmented, silo-based groups and a team that thinks and acts as one. In the business world, when teams are not aligned and don't collaborate across the various boundaries, they put the whole organisation at risk. This irritates customers, frustrates employees and causes countless lost opportunities. Think One Team gives you the step-by-step guide to unlock the potential in your own team and to inspire others by showing them that the era of silo thinking is over. Break down old and outdated silo-based thinking habits, and replace them with nimble and effective decision-making methods Drive change through collaboration and co-creation, empowering teams to respond and adapt quickly Coach your team to think, learn and act as a single unit, rather than a fractured collection of independent professionals Leverage an online toolbox brimming with materials that reinforce lessons on how to lead and how to build and connect effective teams Think One Team, 2nd Edition: The Revolutionary 90 Day Plan that Engages Employees, Connects Silos and Transforms Organisations is an engaging book that breaks the cycle of silo-based thinking and empowers your team to thrive in an ever-changing world.

The importance of partial differential equations (PDEs) in modeling phenomena in engineering as well as in the physical, natural, and social sciences is well known by students and practitioners in these fields. Striking a balance between theory and applications, Fourier Series and Numerical Methods for Partial Differential Equations presents an introduction to the analytical and numerical methods that are essential for working with partial differential equations. Combining methodologies from calculus, introductory linear algebra, and ordinary differential equations (ODEs), the book strengthens and extends readers' knowledge of the power of linear spaces and linear transformations for purposes of understanding and solving a wide range of PDEs. The book begins with an introduction to the general terminology and topics related to PDEs, including the notion of initial and boundary value problems and also various solution techniques. Subsequent chapters explore: The solution process for Sturm-Liouville boundary value ODE problems and a Fourier series representation of the solution of initial boundary value problems in PDEs The concept of completeness, which introduces readers to Hilbert spaces The application of Laplace transforms and Duhamel's theorem to solve time-dependent boundary conditions The finite element method, using finite dimensional subspaces The finite analytic method with applications of the Fourier series methodology to linear version of non-linear PDEs Throughout the book, the author incorporates his own class-tested material, ensuring an accessible and easy-to-follow presentation that helps readers connect presented objectives with relevant applications to their own work. Maple is used throughout to solve many exercises, and a related Web site features Maple worksheets for readers to use when working with the book's one- and multi-dimensional problems. Fourier Series and Numerical Methods for Partial Differential Equations is an ideal book for courses on applied mathematics and partial differential equations at the upper-undergraduate and graduate levels. It is also a reliable resource for researchers and practitioners in the fields of mathematics, science, and engineering who work with mathematical modeling of physical phenomena, including diffusion and wave aspects.

Fourier Methods in Imaging introduces the mathematical tools for modeling linear imaging systems to predict the action of the system or for solving for the input. The chapters are grouped into five sections, the first introduces the imaging “tasks” (direct, inverse, and system analysis), the basic concepts of linear algebra for vectors and functions, including complex-valued vectors, and inner products of vectors and functions. The second section defines «special» functions, mathematical operations, and transformations that are useful for describing imaging systems. Among these are the Fourier transforms of 1-D and 2-D function, and the Hankel and Radon transforms. This section also considers approximations of the Fourier transform. The third and fourth sections examine the discrete Fourier transform and the description of imaging systems as linear «filters», including the inverse, matched, Wiener and Wiener-Helstrom filters. The final section examines applications of linear system models to optical imaging systems, including holography. Provides a unified mathematical description of imaging systems. Develops a consistent mathematical formalism for characterizing imaging systems. Helps the reader develop an intuitive grasp of the most common mathematical methods, useful for describing the action of general linear systems on signals of one or more spatial dimensions. Offers parallel descriptions of continuous and discrete cases. Includes many graphical and pictorial examples to illustrate the concepts. This book helps students develop an understanding of mathematical tools for describing general one- and two-dimensional linear imaging systems, and will also serve as a reference for engineers and scientists
