This book was released on 1992 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Very brief summaries are given on three research topics. Electron impact elastic, excitation, and total cross sections for K were investigated by using elaborate Cl target wave functions in the close-coupling approximation. Photoionization cross sections from ground-state Na were calculated near the 2s22p53s and 2s2p63s inner-shell thresholds; also, the photoionization cross sections of excited 3p 2P{sup o} and 3d 2D states were calculated with the R-matrix methodology near the 2s2p63s thresholds. A numerical approach was developed to calculate the charge transfer matrix elements for ion-atom(ion) collisions; this was used for the proton-hydrogen collision problem as an illustration.

Book excerpt: The Republic of Korea's industrial policy has directed that nation's economy through nearly three decades of spectacular growth. But the authors of this paper maintain that this policy is showing signs of being outmoded. The time has come, the authors argue, for the Korean government to stop managing the economy's structural development and to redefine the responsibilities of business and government. Under this proposed compact, the allocation of resources would shift from the government to the private industrial and financial sectors. The transformation of the government bureaucracy from an ad hoc policy role to one of a transparent and predictable regulator is a key to the success of this undertaking. These new directions would present the government with enormous challenges. Greater competitive discipline and regulatory oversight would be required. While dealing with the complexities of the transition, the government would have to maintain macroeconomic stability and the momentum of savings and investment. For comparison, the study examines the industrial economies of France, Germany, Japan, and the United States, which underwent similar shifts.
Download or read book Atomic Physics of Strongly Correlated Systems Progress Report 1 February 1991 15 January 1992 written by and published by . This book was released on 1992 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the progress made in our continuing study of strongly correlated atomic systems within the last year. We have examined the shape of three-body systems in hyperspherical coordinates by studying the evolution of the density functions with the mass ratio of the particles in the system. We have calculated the ejected electron spectra from the autoionizing states formed in double capture processes in collisions of multiply charged ions with atoms. We have investigated the systematics and the propensity rules of radiative and Auger decay rates of high-lying doubly excited states. We have also studied ion-atom collisions for processes which pose great challenges to detailed theories, by looking into processes where the cross sections are small such as the excitation process in He{sup ++} + H collisions, or by looking into fine details such as the orientation parameters in excitation and charge transfer processes.

Available in PDF, EPUB and Kindle. Book excerpt: This grant has contributed to the establishment of a strong group in Theoretical Atomic and Molecular Physics at Clark Atlanta University. The general thrust of the group has been: (l) the development of novel theoretical methods for application to electron scattering at small-scattering angles, propulsion technologies and planetary atmospheres; 2) the calculation, using extensive configuration-interaction wave functions in sophisticated methodologies of energy levels, optical oscillator strengths, effective collision strengths for use in plasma modeling and photoionization cross sections; and 3) the support of minority students who are underrepresented in the physical and mathematical sciences The acquisition through tho AFOSR research grant of the powerful IBM RISC 6OOO/590 workstation and attendant software as well as the support of a Post-doctoral Fellow and students have improved the research environment at the Center for theoretical Studies of Physical Systems (CTSPS) and impacted the training of students in the Atlanta University Center, the largest consortium of private HBCUs in the nation. National and international visitors and collaborators have been attracted to CTSPS, creating an excellent environment for research, thereby advancing the field of small-angle electron scattering to a level that has never been attained before. The project has been very productive. Twenty-five publications have been generated with an additional six publications submitted for publication in refereed journals. Additionally, 31 papers have been presented at national and international conferences over the past three years.
Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
Download or read book Fundamentals of Electric Propulsion written by Dan M. Goebel and published by John Wiley & Sons. This book was released on 2008-12-22 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
