The composition of modern semiconductor heterostructures can be controlled precisely on the atomic scale to create low-dimensional systems. These systems have revolutionised semiconductor physics, and their impact on technology, particularly for semiconductor lasers and ultrafast transistors, is widespread and burgeoning. This book provides an introduction to the general principles that underlie low-dimensional semiconductors. As far as possible, simple physical explanations are used, with reference to examples from actual devices. The author shows how, beginning with fundamental results from quantum mechanics and solid-state physics, a formalism can be developed that describes the properties of low-dimensional semiconductor systems. Among numerous examples, two key systems are studied in detail: the two-dimensional electron gas, employed in field-effect transistors, and the quantum well, whose optical properties find application in lasers and other opto-electronic devices. The book includes many exercises and will be invaluable to undergraduate and first-year graduate physics or electrical engineering students taking courses in low-dimensional systems or heterostructure device physics.

The MSP430 is a simple 16-bit microcontroller with a compact and economical CPU containing only 27 instructions and 16 registers. It offers other advantages which make it suitable for low power applications: a rich variety of peripherals for analog input and output; rapid processing wake up time; the treatment of data and address on equal footing.
Introduction to the MSP430 combines a tutorial approach with a description of the CPU and main peripherals. The tutorial builds from a basic program for lighting LEDs to the use of a timer. It uses the C programming language from the start but programs are also developed in assembly language to show how a program interacts with the hardware. To demonstrate the special features of the MSP430 full coverage is given to the instruction set, sigma-delta analog-digital converters and timers. Finally, the book gives an introduction to the MSP430 which extends the architecture to address more memory and which provides a bridge to the ARM 7 processor.

THE AMERICAN TURF - HISTORY OF THE THOROUGHBRED, TOGETHER WITH PERSONAL REMINISCENCES BY THE AUTHOR, WHO, IN TURN, HAS BEEN JOCKEY, TRAINER AND OWNER 1906 BY JOHN H. DAVIS. PREFACE For a decade more than the three score years and ten allotted by a gracious Providence toman I havebeen awaiting the solemn call which comes to all human kind to weigh in, and then to the great Steward make account of the use to which I put the opportunities that came to me. In the active competition of life, when rivalries were keen, when ambitions created new fields and contests kept alert both mind and body, there was little time, indeed, to do more than merely store away in unclassified groups in memory events and incidents each one deserving of a separate chapter. To write a history of the American turf had long been a cherished project, but each day of a life of practically unremitting and exacting labor interfered until the westering sun of my eightieth yearwarns me that I must be up and doing if I would achieve my cherished ambition and leave behind me something which I trust will be worthy tribute to the best and the noblest sport that it is given to man to enjoy. If in the chapters which are to come there should be noted a tone of enthusiastic optimism, let the reader realize that sixty-five years of my life were spent inthe activities of the turf as a jockey, a trainer and an owner that I have seen, and in many of them personally participated, practically all of the great contests which gave fame to our thoroughbreds that I have traveled on foot through valleys and over mountains, when but rough paths pointed the way between places nowdrawn close together by the bands of great trunk line railroads, leading the horse that was on conquest bent that I spent weary weeks on journeys that now would be but the occupation of one brief day of luxurious travel that I have seen the upward and the onward progress which has marked the rise of the thoroughbred in America from a little meet in some isolated though sport-loving place to the magnificent seasons of Belmont Park. No optimism of my earliest and most enthusiastic days could have possibly created for me a grander vista than that which in reality has come. No dream that I might have had more than a half century ago could have conjured up the multitude that on last Decoration Day I saw passthrough the gates of the vastest and the best appointed race course in the world. No fancy of the years gone by could have pictured the popularity of the sport which has so entwined itself about the American thoroughbred. A long cry truly from famed old Governor Garys Lane, where our own Washington of everblessed memory presided and where he raced his own horse Magnolia, to the great courses which now cater to the scores of thousandswho pay their devoirs to our noble horse. Nor do I believe that we yet have reached our highest in the sport. It is better conserved to-day, it has a more than ever before. popular patronage, it is better regulated It is difficult to maintain ones poise and listen to the croak- ings of those who allege they fear disaster and already can discern ruin. Racing has had its dark days, as what sport or what man or what nation has not, and it may continue so to have at uncertain periods. But I have been in it a lifetime longer than it has been the good fortune of many to enjoy, and I have seen itsgood name assailed, and itspatrons criticised, and attempts made to thwart its progress but ever and always it has come out of its difficulties better and stronger than it was. And it did so because of the love of contest which is characteristic of the American people. The American citizen is essentially a man who glories in struggles for supremacy whether it be man or horse that battles, his sympathies are at once enlisted and aroused...
