 Free Download Power Trade-offs and Low-Power in Analog CMOS ICs by Mihai A. T. Sanduleanu , A. J. M. Tuijl English | PDF | 2002 | 228 Pages | ISBN : 0792376420 | 13.9 MB The enormous rise of digital applications in the last two decades arouses the suggestion that analog techniques will lose their importance. However in applications that work with digital signals analog techniques are still very important for a number of reasons. First the signal that must be processed or stored may be analog at the input and output of the system. Second when digital circuits must operate at high speed the analog behavior becomes important again. And third when only limited bandwidth and signal to noise ratio is available the theoretical maximum data rate is determined by Shannon's law. This theoretical limit can only be approximated in practice when complex modulation schemes are used, and after this modulation process the signal is analog again. Of course this does effect the tremendous advantage of digital signals compared to analog signals. Where analog signals deteriorate every time they are processed or stored, digital signals can be recovered perfectly when they are tailored to the properties of the system they are used for. The accuracy of digital signal processing is only limited by practical constraints and many digital signals can be compressed very effective so that after compression they use less bandwidth then their analog counterparts. In any aplication there will thus be analog and digital parts and often the choice has to be made if an analog or a digital solution is preferred for a certain function.  Free Download Power Aware Design Methodologies by Massoud Pedram, Jan M. Rabaey English | PDF | 2002 | 533 Pages | ISBN : 1402071523 | 23 MB Power Aware Design Methodologies was conceived as an effort to bring all aspects of power-aware design methodologies together in a single document. It covers several layers of the design hierarchy from technology, circuit logic, and architectural levels up to the system layer. It includes discussion of techniques and methodologies for improving the power efficiency of CMOS circuits (digital and analog), systems on chip, microelectronic systems, wirelessly networked systems of computational nodes and so on. In addition to providing an in-depth analysis of the sources of power dissipation in VLSI circuits and systems and the technology and design trends, this book provides a myriad of state-of-the-art approaches to power optimization and control.  Free Download Svein Jentoft, Arne Eide, "Poverty Mosaics: Realities and Prospects in Small-Scale Fisheries" English | 2011 | pages: 528 | ISBN: 9400715811, 9400792840 | PDF | 12,8 mb Small-scale fisheries are a major source of food and employment around the world. Yet, many small-scale fishers work in conditions that are neither safe nor secure. Millions of them are poor, and often they are socially and politically marginalized. Macro-economic and institutional mechanisms are essential to address these poverty and vulnerability problems; however, interventions at the local community level are also necessary. This requires deep understanding of what poverty means to the fishers, their families and communities; how they cope with it; and the challenges they face to increase resiliency and improve their lives for the better.  Free Download Positron Profilometry: Probing Material Depths for Enhanced Understanding by Jerzy Dryzek English | PDF EPUB (True) | 2023 | 146 Pages | ISBN : 3031410920 | 25.8 MB This book provides a comprehensive overview of positron profilometry, specifically focusing on the analysis of defect depth distribution in materials. Positron profilometry plays a crucial role in understanding and characterizing defects in a wide range of materials, including metals, semiconductors, polymers, and ceramics. By analyzing the depth distribution of defects, researchers can gain insights into various material properties, such as crystal structure, defect density, and diffusion behavior. The author's extensive research spanning a period of two decades has primarily centered on subsurface zones. These regions, located beneath the surface and subjected to various surface processes, play a crucial role in generating defect distributions. Three experimental techniques and their data analysis are described in detail: a variable-energy positron beam (VEP) called sometimes a slow positron beam, a technique called implantation profile depth scanning (DSIP), and a sequential etching (SET) technique. The usability of these techniques is illustrated by many examples of measurements by the author and others.  Free Download Glen M Williford, Leo K. Polaski, "Portsmouth Harbor's Military and Naval Heritage" English | 2004 | pages: 128 | ISBN: 0738536474, 1531621392 | EPUB | 46,0 mb Including more than two hundred vintage photographs and illustrations, Portsmouth Harbor's Military and Naval Heritage chronicles the history of the Piscataqua River's naval shipyard and harbor defenses. Long before it became home to one of the U.S. Navy's first federal shipyards, the harbor at Portsmouth, New Hampshire, and Kittery, Maine, was protected by gun batteries, mainly at Fort Point, New Castle, New Hampshire. By the end of World War II, modern concrete batteries mounting guns of ever longer range had been constructed at this and three other forts straddling the river's mouth. These fortifications reflected the increasingly important role of the shipyard, dedicated after 1917 to building submarines that contributed significantly to the World War II victory.  Free Download George R Miller, "Portland Rose Festival" English | 2013 | pages: 130 | ISBN: 1531664946, 0738596140 | EPUB | 59,8 mb At the end of the Lewis and Clark Exposition in 1905, the president of the Portland Street Fair and Carnival Association, E.W. Rowe, presented the idea of an annual festival to Portland mayor Harry Lane. From that idea came the first Rose Festival, called the Rose Carnival and Fiesta, held June 20-22, 1907. It was hailed as a huge success. "There is no reason in the world why Portland should not hold a rose festival every year," remarked the Oregonian on June 21. "Everyone will be happier and better all the rest of the year for the festival of roses." And indeed, that has been the case. From just a three-day event, the Rose Festival has expanded over the years to include many activities covering several months every spring and summer.

Free Download Michael Perry, "Population: 485- Meeting Your Neighbors One Siren at a Time" English | 2015 | pages: 234 | ISBN: 0061363502, 0060198524 | EPUB | 1,8 mb "Part portrait of a place, part rescue manual, part rumination of life and death, Population: 485 is a beautiful meditation on the things that matter."-Seattle Times  Free Download Raphael Sassower, "Popper's Legacy: Rethinking Politics, Economics, and Science" English | 2006 | pages: 162 | ISBN: 0773531769, 0773531750 | PDF | 0,8 mb Karl Popper has had an extraordinary influence on scientific and social thought. Widely regarded as one of the greatest philosophers of science of the twentieth century, he was also a highly influential social and political philosopher, a proponent and defender of the open society. Popper's Legacy examines all aspects of his work, in particular his moral and psychological insights. Once Popper's scientific legacy is couched in political and moral terms, it becomes apparent that his concern for individual autonomy does not come at the expense of institutional guidelines and social conventions. Instead, these guidelines turn out to be essential sanctions for individual freedom. Popper envisions the conduct of the scientific community as paralleling the conduct of any democratically established community, where critical rationality guides the words and actions of all participants and leadership can be changed without violence. Raphael Sassower reveals the debt many intellectual movements - such as feminism, and postmodernism - owe to Popper.
