After the Civil War, the building of the transcontinental railroad was the nineteenth century's most transformative event. Beginning in 1842 with a visionary's dream to span the continent with twin bands of iron, Empire Express captures three dramatic decades in which the United States effectively doubled in size, fought three wars, and began to discover a new national identity. From self--made entrepreneurs such as the Union Pacific's Thomas Durant and era--defining figures such as President Lincoln to the thousands of laborers whose backbreaking work made the railroad possible, this extraordinary narrative summons an astonishing array of voices to give new dimension not only to this epic endeavor but also to the culture, political struggles, and social conflicts of an unforgettable period in American history.
Software engineering has over the years been applied in many different fields, ranging from telecommunications to embedded systems in car and aircraft industry as well as in production engineering and computer networks. Foundations in software technology lie in models allowing to capture application domains, detailed requirements, but also to understand the structure and working of software systems like software architectures and programs. These models have to be expressed in techniques based on discrete mathematics, algebra and logics. However, according to the very specific needs in applications of software technology, formal methods have to serve the needs and the quality of advanced software engineering methods, especially taking into account security aspects in Information Technology. This book presents mathematical foundations of software engineering and state-of-the-art engineering methods in their theoretical substance in the step towards practical applications to examine software engineering techniques and foundations used for industrial tasks.
The contributions in this volume emerged from lectures of the 25th International Summer School on Engineering Theories of Software Intensive Systems, held at Marktoberdorf, Germany from August 3 to August 15, 2004.
