Математика в огне. Нескучный неучебник

Джейсон Уилкс

Если вам не давалась математика, возможно, дело было не в вас, а в том, как вам ее преподносили. Эту книгу можно назвать провокацией. Предложенный подход к изучению математики меняет привычное представление о ней как о скучной и абстрактной дисциплине, которую нужно просто вызубрить. Автор вместе с читателем создает математическую вселенную, увлекательную и увлекающую. Он не постулирует математические концепции, а постепенно выводит их из нашего понимания окружающего мира. По мнению Джейсона Уилкса, система образования блестяще сконструирована, чтобы наказывать творческие способности; чтобы учить, как правильно писать математические символы, а не думать самостоятельно. Его книга будет для вас умным и немного безумным учителем, который поможет дойти до открытий и определений самостоятельно, а не заучивать их. Важное замечание: эта книга может стать прекрасным дополнением к любому стандартному учебнику, но не заменить его!

Geometric and Topological Mesh Feature Extraction for 3D Shape Analysis

Gerard Subsol

Three-dimensional surface meshes are the most common discrete representation of the exterior of a virtual shape. Extracting relevant geometric or topological features from them can simplify the way objects are looked at, help with their recognition, and facilitate description and categorization according to specific criteria. This book adopts the point of view of discrete mathematics, the aim of which is to propose discrete counterparts to concepts mathematically defined in continuous terms. It explains how standard geometric and topological notions of surfaces can be calculated and computed on a 3D surface mesh, as well as their use for shape analysis. Several applications are also detailed, demonstrating that each of them requires specific adjustments to fit with generic approaches. The book is intended not only for students, researchers and engineers in computer science and shape analysis, but also numerical geologists, anthropologists, biologists and other scientists looking for practical solutions to their shape analysis, understanding or recognition problems.

Estimation of Stochastic Processes with Stationary Increments and Cointegrated Sequences

Maksym Luz

Estimation of Stochastic Processes is intended for researchers in the field of econometrics, financial mathematics, statistics or signal processing. This book gives a deep understanding of spectral theory and estimation techniques for stochastic processes with stationary increments. It focuses on the estimation of functionals of unobserved values for stochastic processes with stationary increments, including ARIMA processes, seasonal time series and a class of cointegrated sequences. Furthermore, this book presents solutions to extrapolation (forecast), interpolation (missed values estimation) and filtering (smoothing) problems based on observations with and without noise, in discrete and continuous time domains. Extending the classical approach applied when the spectral densities of the processes are known, the minimax method of estimation is developed for a case where the spectral information is incomplete and the relations that determine the least favorable spectral densities for the optimal estimations are found.

Leading for Organisational Change

Jennifer Emery

Harness the seven key elements of successful organisational change Leading for Organisational Change is an intelligent and practical guide to the human side of merger integration and other organisational change. Building a clear sense of common purpose and then reinforcing it through storytelling can underpin the success of an integration or significant change programme. Pulling together the best thinking from neuroscience, psychology and business, and her rich personal experience in twenty years of leading change projects in professional services organisations and other people-centred businesses, author Jennifer Emery presents a framework for change rooted in seven key themes that help organisations establish their BECAUSE: belonging, evolution, confidence, agility, understanding, simplicity and energy.

Effective Data Storytelling

Brent Dykes

Master the art and science of data storytelling—with frameworks and techniques to help you craft compelling stories with data. The ability to effectively communicate with data is no longer a luxury in today’s economy; it is a necessity. Transforming data into visual communication is only one part of the picture. It is equally important to engage your audience with a narrative—to tell a story with the numbers. Effective Data Storytelling will teach you the essential skills necessary to communicate your insights through persuasive and memorable data stories. Narratives are more powerful than raw statistics, more enduring than pretty charts. When done correctly, data stories can influence decisions and drive change. Most other books focus only on data visualization while neglecting the powerful narrative and psychological aspects of telling stories with data. Author Brent Dykes shows you how to take the three central elements of data storytelling—data, narrative, and visuals—and combine them for maximum effectiveness. Taking a comprehensive look at all the elements of data storytelling, this unique book will enable you to: Transform your insights and data visualizations into appealing, impactful data stories Learn the fundamental elements of a data story and key audience drivers Understand the differences between how the brain processes facts and narrative Structure your findings as a data narrative, using a four-step storyboarding process Incorporate the seven essential principles of better visual storytelling into your work Avoid common data storytelling mistakes by learning from historical and modern examples Effective Data Storytelling: How to Drive Change with Data, Narrative and Visuals is a must-have resource for anyone who communicates regularly with data, including business professionals, analysts, marketers, salespeople, financial managers, and educators.

Fractional Brownian Motion

Yuliya Mishura

This monograph studies the relationships between fractional Brownian motion (fBm) and other processes of more simple form. In particular, this book solves the problem of the projection of fBm onto the space of Gaussian martingales that can be represented as Wiener integrals with respect to a Wiener process. It is proved that there exists a unique martingale closest to fBm in the uniform integral norm. Numerical results concerning the approximation problem are given. The upper bounds of distances from fBm to the different subspaces of Gaussian martingales are evaluated and the numerical calculations are involved. The approximations of fBm by a uniformly convergent series of Lebesgue integrals, semimartingales and absolutely continuous processes are presented. As auxiliary but interesting results, the bounds from below and from above for the coefficient appearing in the representation of fBm via the Wiener process are established and some new inequalities for Gamma functions, and even for trigonometric functions, are obtained.
