Constant Vigilance
Beretter om det britiske "Royal Air Force Regiment" og dets indsats i Sydøstasien under 2. verdenskrig. Regimentet var en specialstyrke til forsvar af flyvepladser og andre nøglepunkter.
The Constant Economy
Since the industrial revolution, the economies of developed nations have grown at the expense of the natural world. But the earth's resources are finite, climate change threatens to dramatically transform how and where we live, and the global economic system is in disarray. One way or another we will have to change. The longer we delay, the more our societies will be at the mercy of events and the harsher the eventual adjustments. Fortunately, as this book shows, there is an alternative. Zac Goldsmith argues for the creation of what he calls a 'constant economy' - in which resources are valued not wasted, food is grown sustainably, and goods are built to last. The constant economy operates at the human scale, and above all it recognises nature's limits. He shows that almost every action needed to support the environment is already being carried out somewhere in the world, by companies, communities and governments determined to blaze a trail. Where they have done the right thing, their customers and voters have rewarded them. Practical solutions exist, and they are brought together and set out in this ground-breaking book.
Recent Advances in Metrology and Fundamental Constants
Over the last decade of the 20th century, many improvements took place in the field of metrology and fundamental constants. These developments and improvements are discussed in this book. The old caesium SI second definition has found a new realization with the fountain approach, replacing the classical thermal atomic beam. The use of cold atom techniques, slowed down and cooled, has opened a number of unexpected avenues for metrology and fundamental constants, one of these possibilities being the atom interferometry. Another development was the demonstration of the possiblility of performing a direct frequency division in the visible, using short femtosecond pulses. Many other developments are also discussed.
Advanced Programming in the UNIX Environment
For more than twenty years, serious C programmers have relied on one book for practical, in-depth knowledge of the programming interfaces that drive the UNIX and Linux kernels: W. Richard Stevens’ Advanced Programming in the UNIX® Environment. Now, once again, Rich’s colleague Steve Rago has thoroughly updated this classic work. The new third edition supports today’s leading platforms, reflects new technical advances and best practices, and aligns with Version 4 of the Single UNIX Specification. Steve carefully retains the spirit and approach that have made this book so valuable. Building on Rich’s pioneering work, he begins with files, directories, and processes, carefully laying t...
A new standard model of cosmology: Time-varying fundamental constants and the evolution of the universe
A new theoretical framework is presented to explain the evolution of the universe based on the time-varying properties of the fundamental constants. A static universe with time-varying constants can explain the origin of the cosmic microwave background radiation, CMB anisotropies, the CMB cold spot, the observed redshift-distance modulus data, the origin and composition of dark matter in the universe, galaxy cluster mass estimates, Milky Way galaxy luminosity estimates, population II stellar properties, vacuum-photon interactions, energy cycling between matter, radiation and vacuum field components, time-varying Higgs mechanism and particle mass, and the observed matter-antimatter dichotomy. This is a complete theoretical framework that explains the observable universe and resolves many of the issues with modern-day cosmology.
Quantum Metrology and Fundamental Physical Constants
The object of this NATO Advanced Study Institute was to pre sent a tutorial 'introduction both to the basic physics of recent spectacular advances achieved in the field of metrology and to the determination of fundamental physical constants. When humans began to qualify their description of natural phenomena, metrology, the science of measurement, developed along side geometry and mathematics. However, flam antiquity to modern times, the role of metrology was mostly restricted to the need of commercial, social or scientific transactions of local or at most national scope. Beginning with the Renaissance, and particularly in western Europe during the last century, metrology rapidly developed an international character as a result of growing needs for more accurate measurements and common standards in the emerging indus trial society. Although the concerns of metrology are deeply rooted to fundamental sciences, it was, until recently, perceived by much of the scientific community as mostly custodial in character.
MIPS Pipeline Cryptoprocessor
The design and implementation of a crypto processor based on Cryptographic algorithms can be used in wide range of electronic devices, include PCs, PDAs, hardware security modules, web servers etc. The growing problem of breaches in information security in recent years has created a demand for earnest efforts towards ensuring security in electronic processors. The successful deployment of these electronic processors for ecommerce, Internet banking, government online services, VPNs, mobile commerce etc., are dependent on the effectiveness of the security solutions. These security concerns are further compounded when resource-constrained environments and real-time speed requirements have to be considered in next generation applications. Consequently, these IT and Network security issues have been a subject of intensive research in areas of computing, networking and cryptography these last few years. Computational methodologies, computer arithmetic, and encryption algorithms need deep investigation and research to obtain efficient integrations of crypto-processors, with desirable improvements and optimizations. Approaches on silicon achieve high values of speed and bandwidth.
