The Floating Point Multiplier is a wide variety for increasing accuracy, high speed and high performance in reducing delay, area and power consumption. The floating point is used for algorithms of Digital Signal Processing and Graphics. Many floating point multipliers are used to reduce the area that perform in both the single precision and the double precision in multiplication, addition and subtraction. Here, the scientific notations sign bit, mantissa and exponent are used. The real numbers are divided into two components: fixed component of significant range (lack of dynamic range) and exponential component in floating point (largest dynamic range). The authors convert decimal to floating point and normalize the exponent part and rounding operation to reduce latency. The mantissa of two values are multiplied and the exponent part is added. The sign results with exclusive-or are obtained. Then, the final result of shift and add floating point multiplier is compared with booth multiplication.

Daniel Albero Santacreu presents a wide overview of certain aspects of the pottery analysis and summarizes most of the methodological and theoretical information currently applied in archaeology in order to develop wide and deep analysis of ceramic pastes. The book provides an adequate framework for understanding the way pottery production is organised and clarifies the meaning and role of the pottery in archaeological and traditional societies. The goal of this book is to encourage reflection, especially by those researchers who face the analysis of ceramics for the first time, by providing a background for the generation of their own research and to formulate their own questions depending on their concerns and interests. The three-part structure of the book allows readers to move easily from the analysis of the reality and ceramic material culture to the world of the ideas and theories and to develop a dialogue between data and their interpretation. Daniel Albero Santacreu is a Lecturer Assistant in the University of the Balearic Islands, member of the Research Group Arqueo UIB and the Ceramic Petrology Group. He has carried out the analysis of ceramics from several prehistoric societies placed in the Western Mediterranean, as well as the study of handmade pottery from contemporary ethnic groups in Northeast Ghana.

As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

The Alps, with their outstanding outcrop conditions, represent a superb natural laboratory for many geological processes, and have played a crucial role in the history of geology. This book gives an up-to-date and holistic overview of the key aspects of Alpine geology. After a brief presentation of the plate tectonic framework, the rock suites are discussed, starting with the pre-Triassic crystalline basement, followed by Paleozoic, Mesozoic and Cenozoic sedimentary sequences. The lithological description of the rock types is supplemented by a discussion of their paleogeographic and plate tectonic contexts. The book goes on to describe the structure of the Alps (including the Jura Mountains and the Alpine foreland to the north and south) illustrated by numerous cross-sections. The evolution of the Alps as a mountain chain incorporates a discussion of the Alpine metamorphic history and a compilation of orogenic timetables. The final sections cover the evolution of Alpine drainage patterns and the region’s glacial history. Readership: The book is essential reading for students and lecturers on Alpine courses and excursions, and all earth-scientists interested in the geology of the region.

This is the first book in English reviewing and updating the geology of the whole Apennines, one of the recent most uplifted mountains in the world. The Apennines are the place from which Steno (1669) first stated the principles of geology. The Apennines also represent amongst others, the finding/testing sites of processes and products like volcanic eruptions, earthquakes, olistostromes and mélanges (argille scagliose), salinity crisis, geothermal fluids, thrust-top basins, and turbidites (first represented in a famous Leonardo's painting). As such, the Apennines are a testing and learning ground readily accessible and rich of any type of field data. A growing literature is available most of which is not published in widely available journals. The objective of the book is to provide a synthesis of current data and ideas on the Apennines, for the most part simply written and suitable for an international audience. However, sufficient details and in-depth analyses of the various complex settings have been presented to make this material useful to professional scholars and to students of senior university courses.

The fact that most ancient marble portraits were once intentionally polychrome has always been lurking at the corners of art historical and archaeological research. Despite the fact, that the colours of the sculpted forms completed, enhanced and even extended the plastic shapes, the topic has not been devoted much dedicated attention. This book represents the first full-length academic monograph which explores the original polychromy of Roman white marble portraiture. It presents results from scientific analysis of portraits in statuary and bust formats dating to the first three centuries CE. The book also explores the cultural and social significance of colours in their original contexts, and how the immaterial affects of the polychrome, three-dimensional images can be integrated into the traditional research into ancient portraiture, which has tended to place overwhelming emphasis on iconography, typology and biography. By doing so the ancient sculpted marble form, as we know it, will be exposed and confronted, and the impact of manipulated material effects, that were meant to evoke a broad range of multisensory experiences, will be emphasized. The book puts forth a new way of analysis to be tested and developed in the future.

Geofluids: Developments in Microthermometry, Spectroscopy, Thermodynamics, and Stable Isotopes is the definitive source on paleofluids and the migration of hydrocarbons in sedimentary basins—ideal for researchers in oil and gas exploration. There's been a rapid development of new non-destructive analytical methods and interdisciplinary research that makes it difficult to find a single source of content on the subject of geofluids. Geoscience researchers commonly use multiple tools to interpret geologic problems, particularly if the problems involve fluid-rock interaction. This book perfectly combines the techniques of fluid inclusion microthermometry, stable isotope analyses, and various types of spectroscopy, including Raman analysis, to contribute to a thorough approach to research. Through a practical and intuitive step-by-step approach, the authors explain sample preparation, measurements, and the interpretation and analysis of data related to thermodynamics and mineral-fluid equilibria. - Features working examples in each chapter with step-by-step explanations and calculations - Broad range of case studies aid the analytical and experimental data - Includes appendices with equations of state, stable isotope fractionation equations, and Raman identification tables that aid in identification of fluid inclusion minerals - Authored by a team of expert scientists who have more than 60 years of related experience in the field and classroom combined
