Take advantage of Kotlin's concurrency primitives to write efficient multithreaded applications Key Features Learn Kotlin's unique approach to multithreading Work through practical examples that will help you write concurrent non-blocking code Improve the overall execution speed in multiprocessor and multicore systems Book Description The primary requirements of modern-day applications are scalability, speed, and making the most use of hardware. Kotlin meets these requirements with its immense support for concurrency. Many concurrent primitives of Kotlin, such as channels and suspending functions, are designed to be non-blocking and efficient. This allows for new approaches to concurrency and creates unique challenges for the design and implementation of concurrent code. Learning Concurrency in Kotlin addresses those challenges with real-life examples and exercises that take advantage of Kotlin's primitives. Beginning with an introduction to Kotlin's coroutines, you will learn how to write concurrent code and understand the fundamental concepts needed to be able to write multithreaded software in Kotlin. You'll explore how to communicate between and synchronize your threads and coroutines to write asynchronous applications that are collaborative. You'll also learn how to handle errors and exceptions, as well as how to leverage multi-core processing. In addition to this, you'll delve into how coroutines work internally, allowing you to see the bigger picture. Throughout the book you'll build an android application - an RSS reader - designed and implemented according to the different topics covered in the book What you will learn Understand Kotlin's approach to concurrency Implement sequential and asynchronous suspending functions Create suspending data sources that are resumed on demand Explore the best practices for error handling Use channels to communicate between coroutines Uncover how coroutines work under the hood Who this book is for If you're a Kotlin or Andr

Maintaining an accurate Common Operational Picture (COP) is a strategic requirement for efficient and successful missions in both disaster response and battlefield scenarios. Past practices include utilizing cellular, radio, and computer based communication methods and updating individual maps accordingly. A drawback of these practices has been interoperability of these devices as well as accurate reporting and documentation among different entities of the effort. Recent advances in technology have led to the utilization of collaborative maps for maintaining a COP amongst command centers. Despite the advantages this technique offers, it does not address the difficulties surrounding receiving reports from field entities as well as ensuring these entities also have good situational awareness. The goal of this research is to explore smartphone capabilities in conjunction with cloud computing to determine how they can extend the benefits of collaborative maps to mobile users while simultaneously ensuring command centers are receiving accurate, up-to-date reports from the field.

The market for mobile devices is constantly growing, as is the market for electronic entertainment such as computer games. Mobile entertainment applications will soon have a significant share of today's software market. Since the latest success of innovative interaction devices e.g. the Wiimote, Sony Move and Microsoft Kinect many experts forecast a great potential for mobile gaming driven by these new interaction techniques. Following this trend, the goal of this project is to develop a simple mobile game and integrating the mastering of multimodal interactions techniques as core game concept. The conception and realization of this application for mobile devices followed an iterative design approach dedicated to the efficient design on multimodal post WIMP interfaces, also known as reality based user interfaces [3].

Heterogeneous data sources management is a big challenge for complex projects, especially in the situation of sensor net work. The incompatibility of different data sources makes it complicated for a project to modify databases in use or adapt to new sensors. In this paper, we propose a middleware solution to address the problem. The middleware uses an abstract class to shield the differences among heterogeneous data sources and creates a data source service wrapper for each. Both permanent data info and real-time data flows should pass through the middleware during communication of data sources and application. And by implementing a corresponding data source service wrapper, it's very convenient to add a new data source. At the same time, the middleware uses XML to accomplish data mapping and transmission, so as to solve the incompatibility of data sources schema and ensure platform independence. We deployed the middleware to our E-Health project. Our experience has proved the flexibility and extensibility of the middleware.
