Available in PDF, EPUB and Kindle. Book excerpt: The 120-cell Punched-card Modifiable Logic Array is a repetitive eight-neighbor array of identical NAND gates that can be organized into different data processing subsystems. The signal interconnections between gates are controlled through punched-card operation; any subset of eight-neighbor connections can be made. This versatile and flexible logic array was fabricated for evaluating and verifying cellular logic concepts that appear to have utility for multipurpose or multifunctional arrays. Such arrays could be used in Air Force signal or data processing systems to enhance their flexibility. The array is described, the mode of interconnection control is outlined, and an example of the implementation of a ring oscillator and binary counter chain is presented. (Author).

Download or read book Punched Card Systems and the Early Information Explosion 1880 1945 written by Lars Heide and published by JHU Press. This book was released on 2009-04-27 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a time when Internet use is closely tracked and social networking sites supply data for targeted advertising, Lars Heide presents the first academic study of the invention that fueled today’s information revolution: the punched card. Early punched cards helped to process the United States census in 1890. They soon proved useful in calculating invoices and issuing pay slips. As demand for more sophisticated systems and reading machines increased in both the United States and Europe, punched cards served ever-larger data-processing purposes. Insurance companies, public utilities, businesses, and governments all used them to keep detailed records of their customers, competitors, employees, citizens, and enemies. The United States used punched-card registers in the late 1930s to pay roughly 21 million Americans their Social Security pensions, Vichy France used similar technologies in an attempt to mobilize an army against the occupying German forces, and the Germans in 1941 developed several punched-card registers to make the war effort—and surveillance of minorities—more effective. Heide’s analysis of these three major punched-card systems, as well as the impact of the invention on Great Britain, illustrates how different cultures collected personal and financial data and how they adapted to new technologies. This comparative study will interest students and scholars from a wide range of disciplines, including the history of technology, computer science, business history, and management and organizational studies.

Available in PDF, EPUB and Kindle. Book excerpt: A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.
