The latter promotes bonding and densification between particles. Too low pressure values may cause contact overheating or disruptive sparks whereas too high values may result in unsatisfactory powder sintering due to low heat dissipation.Besides, high contact temperatures are responsible of marked local stressstrain field which, in turn, affect the local contact resistances in a complex manner.• Discusses available methodologies to build, validate and use internal rate models.• Demonstrates how to use statistical packages for building statistical-based credit rating systems.Abstract: Multiphysics contacts in SPS systems are special interfaces between two conducting surfaces ensuring the passage of electric currents and/or heat flow across them.They can be of two types, namely microscopic (particle scale) and macroscopic (device scale).
Since 2007 she is head of the department « Environmental Technology » at the Competence Center of Material Moisture (CMM).This book provides a thorough analysis of internal rating systems.Two case studies are devoted to building and validating statistical-based models for borrowers’ ratings, using SPSS-PASW and SAS statistical packages. It thus generalizes (and, indeed, includes as a special case) the T. Lee and Friedberg 1989 BEC theory of cuprate superconductors where, however, no explicit mention of two-hole pairs is even ever made. Abstract: The generalized Bose-Einstein condensation (GBEC) formalism [1-4] of superconducting charge carriers hinges on three separate new ingredients, it: a) treats Cooper pairs (CPs) as actual bosons which are distinct from BCS pairs which strictly speaking are not bosons, b) includes two-hole pairs on an equal footing with two-electron ones, and c) naturally incorporates in the resulting ternary ideal boson-fermion (BF) gas BF vertex interactions that drive formation/disintegration processes of CPs.
