  • The thermodynamic properties of the metal thin film with face-centered cubic structure at zero pressure are investigated using the statistical moment method (SMM), including the anharmonicity effects of thermal lattice vibrations. The Helmholtz free energy, linear thermal expansion coefficients, specific heats at the constant volume and those at the constant pressure, CV and Cp are derived in closed analytic forms in terms of the power moments of the atomic displacements.

  • The pressure effects on melting temperatures of iron have been studied based on the combination of the modified Lindemann criterion with statistical moment method in quantum statistical mechanics. Numerical calculations have been performed up to pressure 150 GPa. Our results are in good and reasonable agreements with available experimental data.

  • This compendium aims at providing a comprehensive overview of the main topics that appear in any well-structured course sequence in statistics for business and economics at the undergraduate and MBA levels. The idea is to supplement either formal or informal statistic textbooks such as, e.g., “Basic Statistical Ideas for Managers” by D.K. Hildebrand and R.L. Ott and “The Practice of Business Statistics: Using Data for Decisions” by D.S. Moore, G.P. McCabe, W.M. Duckworth and S.L. Sclove, with a summary of theory as well as with a couple of extra examples.

  • This volume describes the essential tools and techniques of statistical signal processing. At every stage, theoretical ideas are linked to specific applications in communications and signal processing. The book begins with an overview of basic probability, random objects, expectation, and second-order moment theory, followed by a wide variety of examples of the most popular random process models and their basic uses and properties.

  • 610 Chapter 14. Statistical Description of Data In the other category, model-dependent statistics, we lump the whole subject of fitting data to a theory, parameter estimation, least-squares fits, and so on. Those subjects are introduced in Chapter 15. Section 14.1 deals with so-called measures of central tendency, the moments of a distribution, the median and mode. In §14.2 we learn to test whether different data sets are drawn from distributions with different values of these measures of central tendency. This leads naturally, in §14.

  • It is always a bold undertaking in a private individual to become the advocate of a suffering people. It is peculiarly difficult at the present moment to be the advocate of the people of Ireland, because there are among them men who have taken the power of redress into their own hands, and committed acts of outrage and rebellion which no sufferings could justify, and which can only tend to aggravate ten-fold the other calamities of their country. Deeply impressed, however, as I am with a conviction that these difficulties stand in my way, I shall yet venture to...

  • TWILIGHT was at hand when the little steamer, slender as a greyhound, cast loose from the pier at Holyhead, made its way cautiously out past the breakwater, and then, gathering speed, headed away across the Irish Sea, straight toward the setting sun. The boat showed many evidences that the Irish Sea can be savage when it chooses. Everything movable about the decks was carefully lashed down; there were railings and knotted ropes everywhere to cling to; and in the saloon the table-racks were set ready at hand, as though they had just been used, and might be needed again at any moment.

  • In many ways this book began about 50 years ago with another book about baseball. When I was growing up in Wayne, New Jersey, in the 1950s, I had two passions—baseball and books. As my interest in baseball grew, I tried to read every book I could find about the sport. One in particular, John Carmichael’s My Greatest Day in Baseball, stood out. Written well before Lawrence Ritter’s classic, The Glory of Their Times, Carmichael’s book is comprised of brief accounts of the memorable moments of legendary players.

  • The calculating results showed that the melting temperature of alloys increases with increasing pressure. The melting temperatures of defect alloys of AgCe, Ag2Ce and Ag3Ce are always slightly lower than that of perfect alloys. Especially, the melting temperatures value of the perfect and defect alloys were almost the same at high pressure. The melting temperature of alloys increase with an increase in amount of Ag containing in the alloys.

  • The explicit expressions of the lattice constant, thermal expansion coefficient, and specific heats at the constant volume and those at the constant pressure, CV and CP of the metal thin films are derived in closed analytic forms in terms of the power moments of the atomic displacements. The thermodynamic quantities of Au, Ag, Cu and Al metal thin films are calculated as a function of the temperature and pressure, and they are in good agreement with the corresponding results obtained from other theoretical calculations and experimental values.

  • The maximum entropy principle has been earlier used to derive the Bose Einstein(B.E.), Fermi Dirac(F.D.) & Intermediate Statistics(I.S.) distribution of statistical mechanics. The central idea of these distributions is to predict the distribution of the microstates, which are the particle of the system, on the basis of the knowledge of some macroscopic data. The latter information is specified in the form of some simple moment constraints.

  • The main objective of this study is to assess geomorphic processes and active tectonics in the Day Nui Con Voi (DNCV) area of Vietnam. For this purpose, a spatial database was collected and constructed, including DEM (Digital Elevation Model) and a geological map. The hypsometric curve (HC) analysis method and its statistical moments were adopted to use for the assessment.
