In San Francisco, CA, in 1858, a young African American man was freed from the claims of a white man who sought to return him to slavery in Mississippi. This was one year after the Supreme Court’s notorious Dred Scott decision and during the California Gold Rush, which saw the population of the state rise from 7,000 to more than 60,000 in a few short years. Archy Lee was the name of the man who, with the aid of anti-slavery lawyers and determined opponents of human bondage, had just won his freedom from the claims of Charles Stovall. With the aid of pro-slavery lawyers and equally determined supporters, Stovall had sought to capture him and carry him back to a far-away slave plantation. Yet the book is not solely about Archy Lee. It is also about the travel routes that the gold-seekers followed to California in the 1850s, some by land over the Great Plains, some by sea around Cape Horn, yet others by sailing from the east coast of North America to the isthmus of Panama, where they crossed over the land there by train and continued on by sea to San Francisco. It is about the efforts of the racially motivated lawmakers to suppress the rights of all of California’s residents except whites, and to subject people of African, Asian, Hispanic, and Native American descent to second-, third-, or even fourth-class citizenship. It is about the residents of the state—including many whites—who fought back against those efforts, seeking to ameliorate or repeal the discriminatory laws and introduce a measure of fairness and justice into California’s civil life. It is about the lawyers and judges who participated in Archy Lee’s legal struggles in 1858, some supporting his claims for freedom while others ferociously opposed them and, in the process, elevated their own political and professional profiles.

Charles Stovall of Mississippi brought his slave into the free state of California leading, in 1852, to the landmark trial to free Archy Lee

This is an innovative study of how British Colonial rule and society in Malayan towns and plantations transformed immigrants into British subjects.

An introduction to the engineering principles of embedded systems, with a focus on modeling, design, and analysis of cyber-physical systems. The most visible use of computers and software is processing information for human consumption. The vast majority of computers in use, however, are much less visible. They run the engine, brakes, seatbelts, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They command robots on a factory floor, power generation in a power plant, processes in a chemical plant, and traffic lights in a city. These less visible computers are called embedded systems, and the software they run is called embedded software. The principal challenges in designing and analyzing embedded systems stem from their interaction with physical processes. This book takes a cyber-physical approach to embedded systems, introducing the engineering concepts underlying embedded systems as a technology and as a subject of study. The focus is on modeling, design, and analysis of cyber-physical systems, which integrate computation, networking, and physical processes. The second edition offers two new chapters, several new exercises, and other improvements. The book can be used as a textbook at the advanced undergraduate or introductory graduate level and as a professional reference for practicing engineers and computer scientists. Readers should have some familiarity with machine structures, computer programming, basic discrete mathematics and algorithms, and signals and systems.
