Book Description
This comprehensive and accessible text discusses all the aspects of Core Java in a simple and easy to understand language. It begins with a discussion on the fundamentals of Java and then goes on to give a description of the various operators provided by Java, different ways of making decisions through branching, and the core concepts of Java, that is, classes, objects and their features. Besides, the text also explains the intricacies of one of the most important features of object-orientation, i.e. inheritance, packages and wrapper classes, arrays, strings, string-buffers, and multi-threaded programming and its intricacies. Finally, it elaborates on the classes and interfaces of lang, util and io packages. The book is intended for the undergraduate students of Engineering [B.Tech. (Computer Science)/B.Tech. (IT)], as well as for undergraduate and postgraduate students of Computer Applications (BCA/MCA), and Computer Science and Information Technology—B.Sc./M.Sc. (Computer Science/IT). Besides, professionals in the field will find the book quite useful. KEY FEATURES : Illustrates the topics discussed with the help of sample programs. Provides a large number of questions at the end of each chapter to test the reader’s understanding of the concepts. Gives a comprehensive Glossary of the terms used in the text.

Book Description
In today’s fast and competitive world, a program’s performance is just as important to customers as the features it provides. This practical guide teaches developers performance-tuning principles that enable optimization in C++. You’ll learn how to make code that already embodies best practices of C++ design run faster and consume fewer resources on any computer—whether it’s a watch, phone, workstation, supercomputer, or globe-spanning network of servers. Author Kurt Guntheroth provides several running examples that demonstrate how to apply these principles incrementally to improve existing code so it meets customer requirements for responsiveness and throughput. The advice in this book will prove itself the first time you hear a colleague exclaim, “Wow, that was fast. Who fixed something?” Locate performance hot spots using the profiler and software timers Learn to perform repeatable experiments to measure performance of code changes Optimize use of dynamically allocated variables Improve performance of hot loops and functions Speed up string handling functions Recognize efficient algorithms and optimization patterns Learn the strengths—and weaknesses—of C++ container classes View searching and sorting through an optimizer’s eye Make efficient use of C++ streaming I/O functions Use C++ thread-based concurrency features effectively

Book Description
Introduction to Data Science: Data Analysis and Prediction Algorithms with R introduces concepts and skills that can help you tackle real-world data analysis challenges. It covers concepts from probability, statistical inference, linear regression, and machine learning. It also helps you develop skills such as R programming, data wrangling, data visualization, predictive algorithm building, file organization with UNIX/Linux shell, version control with Git and GitHub, and reproducible document preparation. This book is a textbook for a first course in data science. No previous knowledge of R is necessary, although some experience with programming may be helpful. The book is divided into six parts: R, data visualization, statistics with R, data wrangling, machine learning, and productivity tools. Each part has several chapters meant to be presented as one lecture. The author uses motivating case studies that realistically mimic a data scientist’s experience. He starts by asking specific questions and answers these through data analysis so concepts are learned as a means to answering the questions. Examples of the case studies included are: US murder rates by state, self-reported student heights, trends in world health and economics, the impact of vaccines on infectious disease rates, the financial crisis of 2007-2008, election forecasting, building a baseball team, image processing of hand-written digits, and movie recommendation systems. The statistical concepts used to answer the case study questions are only briefly introduced, so complementing with a probability and statistics textbook is highly recommended for in-depth understanding of these concepts. If you read and understand the chapters and complete the exercises, you will be prepared to learn the more advanced concepts and skills needed to become an expert.
