The Xamarin tool suite, Xamarin.Android and Xamarin.iOS, is a bridge from .NET into the world of native mobile development. These tools give C sharp developers a direct line into native Android and iOS development, allowing them to build business apps for the Google Play and iTunes app stores. This book helps a developer navigate Android and iOS architecture using .NET. Mobile development makes frequent use of traditional patterns such as MVC, MVVM, Delegates, and Singleton. Pattern-savvy readers will find familiar .NET foundations here with logical bridges into mobile platform-specific implementations. Newcomers to design patterns will find a mobile pattern guidebook. The iOS UI must still be written in Xcode. The Android UI rests on Activities. How are all of these built on a variation of the familiar MVC pattern? The reader will learn about mobile data binding and decoupling of UI and back-end logic for cross-platform code reuse. Application lifecycles on native platforms are unique as mobile and tablet apps spawn, live, pause, and die. The reader will learn how code must respond to changes in state and manage data transfer between views. Web services are the mainstay of mobile data and this is a primer for cross-platform client/service construction. It also explores background data-loading techniques and offline access using local data structures: blueprints for the mobile data layer. This comprehensive recipe and reference book addresses one of the most important and vexing problems in the software industry today: How do we effectively design and develop cross-platform native mobile applications?
This book provides comprehensive information on the conceptual basis of wavelet theory and it applications. Maintaining an essential balance between mathematical rigour and the practical applications of wavelet theory, the book is closely linked to the wavelet MATLAB toolbox, which is accompanied, wherever applicable, by relevant MATLAB codes. The book is divided into four parts, the first of which is devoted to the mathematical foundations. The second part offers a basic introduction to wavelets. The third part discusses wavelet-based numerical methods for differential equations, while the last part highlights applications of wavelets in other fields. The book is ideally suited as a text for undergraduate and graduate students of mathematics and engineering.

Gain practical skills in machine learning for finance, healthcare, and retail. This book uses a hands-on approach by providing case studies from each of these domains: you´ll see examples that demonstrate how to use machine learning as a tool for business enhancement. As a domain expert, you will not only discover how machine learning is used in finance, healthcare, and retail, but also work through practical case studies where machine learning has been implemented. Machine Learning Applications Using Python is divided into three sections, one for each of the domains (healthcare, finance, and retail). Each section starts with an overview of machine learning and key technological advancements in that domain. You´ll then learn more by using case studies on how organizations are changing the game in their chosen markets. This book has practical case studies with Python code and domain-specific innovative ideas for monetizing machine learning. What You Will Learn Discover applied machine learning processes and principles Implement machine learning in areas of healthcare, finance, and retail Avoid the pitfalls of implementing applied machine learning Build Python machine learning examples in the three subject areas Who This Book Is For Data scientists and machine learning professionals.
Proven strategies for maintaining and optimizing legacy code to get the most out of your existing applications. Examples in C-sharp, C++, and Java, as well as strategies for better using the industry standard modeling language: UML 2.0 Addresses the very concrete problems that programmers face working in the context of large untested code bases Based on successful classes for Object Mentor, the author helps organizations maintain older systems rather than go to the cost of developing new ones This book provides programmers with the ability to cost effectively handle common legacy code problems without having to go through the hugely expensive task of rewriting all existing code. It describes a series of practical strategies that developers can employ to bring their existing software applications under control. The author provides useful guidance about how to use these strategies when refactoring or making functional changes to code bases. One of the book´s key points is that it teaches developers to write tests that can be used to make sure they are not unintentionally changing the application as they optimize it. Examples are provided in Java, C++, and Csharp, and the book assumes that the reader has some knowledge of UML notation. Strategies using UML and code in C++ and Java primarily while language independent advice will be delivered in side bars and appendices for language specific users.

Backcover Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts. In this book, Michael Feathers offers start-to-finish strategies for working more effectively with large, untested legacy code bases. This book draws on material Michael created for his renowned Object Mentor seminars: techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control. The topics covered include Understanding the mechanics of software change: adding features, fixing bugs, improving design, optimizing performance Getting legacy code into a test harness Writing tests that protect you against introducing new problems Techniques that can be used with any language or platform-with examples in Java, C++, C, and C# Accurately identifying where code changes need to be made Coping with legacy systems that aren´t object-oriented Handling applications that don´t seem to have any structure This book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes. © Copyright Pearson Education.
