Book Ionospheric Prediction and Forecasting

Download or read book Ionospheric Prediction and Forecasting written by Bruno Zolesi and published by Springer Science & Business Media. This book was released on 2013-09-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how to predict and forecast the state of planet Earth’s ionosphere under quiet and disturbed conditions in terms of dynamical processes in the weakly ionized plasma media of the upper atmosphere and their relation to available modern measurements and modelling techniques. It explains the close relationship between the state of the media and the radio wave propagation conditions via this media. The prediction and forecasting algorithms, methods and models are oriented towards providing a practical approach to ionospherically dependent systems design and engineering. Proper understanding of the ionosphere is of fundamental practical importance because it is an essential part of telecommunication and navigation systems that use the ionosphere to function or would function much better in its nonappearance on the Earth and on any planet with an atmosphere.

Book The Sources of Innovation

Download or read book The Sources of Innovation written by Eric A. von Hippel and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a series of studies showing that the sources of innovation vary greatly; possible sources include innovation users, suppliers of innovation-related components, and product manufacturers. These types of roles are known as functional areas. Specific areas of innovation are marked by having innovators predominantly in one specific functional area. Using empirical data from industrial histories, the authors show that this innovation-function relationship has held in scientific instrument, semiconductor and printed circuit board assembly process innovations. Users are predominantly the innovators in these fields. Also identifies a few industries where manufacturers are typically the innovators and a few others where suppliers tend to be. Analysis of the economic rents of innovation expected by potential innovators can often, if not always, by itself predict the functional source of innovation. Innovating firms will do so only when these rents prove attractive. Two factors suggest that this will tend to limit exploitation of the innovation to a functional area. First, it is difficult for innovators to adopt new functional relationships to their innovations. Second, innovators face a poor ability to capture innovation rents by licensing their innovation-related knowledge to others. This hypothesis and its implications are tested against the empirical datasets used initially. The role of informal R&D know-how trading is also discussed and analyzed using the Prisoner's Dilemma. Guidance is given to innovation managers and policymakers. (CAR).

Book The New Nuclear Forensics

Download or read book The New Nuclear Forensics written by Vitaly Fedchenko and published by Oxford University Press. This book was released on 2015 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear material changes its form and properties as it moves through the nuclear fuel cycle, from one facility to another. Each step of the fuel cycle or each use of the material will inevitably leave its mark. The science of determining the history of a sample of nuclear material through the study of these characteristics is known as nuclear forensics. While nuclear forensic analysis has normally been associated with investigations and prosecutions in the contextof trafficking of nuclear materials or nuclear terrorism, it had wider applications in in national security contexts, such as nuclear non-proliferation, disarmament, and arms control. The New Nuclear Forensics is the first book to give a definitive guide to this broader definition of nuclear forensic analysis. This book describes the various methods used in nuclear forensics, giving first a broad introduction to the process followed by details of relevant measurement techniques and procedures. In each case, the advantages and limitations are outlined. To put these methods in context, the book also recounts the history of the discipline anddescribes the diverse contemporary applications of nuclear forensics.

Book Stratosphere Troposphere Interactions

Download or read book Stratosphere Troposphere Interactions written by K. Mohanakumar and published by Springer Science & Business Media. This book was released on 2008-07-03 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratospheric processes play a signi?cant role in regulating the weather and c- mate of the Earth system. Solar radiation, which is the primary source of energy for the tropospheric weather systems, is absorbed by ozone when it passes through the stratosphere, thereby modulating the solar-forcing energy reaching into the t- posphere. The concentrations of the radiatively sensitive greenhouse gases present in the lower atmosphere, such as water vapor, carbon dioxide, and ozone, control the radiation balance of the atmosphere by the two-way interaction between the stratosphere and troposphere. The stratosphere is the transition region which interacts with the weather s- tems in the lower atmosphere and the richly ionized upper atmosphere. Therefore, this part of the atmosphere provides a long list of challenging scienti?c problems of basic nature involving its thermal structure, energetics, composition, dynamics, chemistry, and modeling. The lower stratosphere is very much linked dynamically, radiatively,and chemically with the upper troposphere,even though the temperature characteristics of these regions are different. The stratosphere is a region of high stability, rich in ozone and poor in water - por and temperature increases with altitude. The lower stratospheric ozone absorbs the harmful ultraviolet (UV) radiation from the sun and protects life on the Earth. On the other hand, the troposphere has high concentrations of water vapor, is low in ozone, and temperature decreases with altitude. The convective activity is more in the troposphere than in the stratosphere.

Book The Evolution of Untethered Communications

Download or read book The Evolution of Untethered Communications written by National Research Council and published by National Academies Press. This book was released on 1998-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems. In addition to advising DARPA on where its investment in information technology for mobile wireless communications systems can have the greatest impact, the book explores the evolution of wireless technology, the often fruitful synergy between commercial and military research and development efforts, and the technical challenges still to be overcome in making the dream of "anytime, anywhere" communications a reality.

Download or read book Crystal Growth written by C. H. L. Goodman and published by Springer. This book was released on 2013-04-17 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade or so the growth of single crystals has assumed enormous importance for both academic research, and technology (particu larly in the field of 'electronics'). The range of fields involved is great: from electro-optics to metal corrosion, from semiconductors to magnetic bubble materials-one can add to the list almost indefinitely. However, while the general principles of crystal growth can be applied aImost right across the board, it turns out that the precise way in which one can grow a particular crystal best varies considerably from material to material. This, of course, is to emphasise the obvious; nonetheless, except in specialised papers in the scientific litera ture , little attempt seems to have been made to deal in any detail with the causes of the difficulties in growing particular kinds of materials and with methods of circumventing them. These specialised papers may be inaccessible, and in any case cannot be, usually, very broad in scope or detailed in treatment simply because of the pressure to keep papers short. And unfortunately few specialised monographs seem to have been produced. These points and others similar emerged repeatedly in discussions with crystal growers from aU parts of the World and indicated that there was a need for a publication which would deal in detail with problems and techniques for specialised areas of crystal growth.
