The early stage of spinodal decomposition was studied by small-angle neutron scattering in the critical mixture of the isotopic blend deutero-polystyrene/polystyrene (d-PS/PS) of equal molecular volume of 1.42 × 106 cm3/mol. The time evolution of this process is described by the dynamical structure factor. The observed time evolution of the fluctuation modes is a non-exponential. The analysis of the data has shown that the non-exponential behavior was attributed to a time-dependent increase of the “range” of the Onsager coefficient.
The Dagstuhl Middle Metamodel (DMM) is an extensible schema for static models of software. It is a middle-level metamodel since it captures program level entities and their relationships, rather than a full abstract syntax graph (lower level), or architectural abstractions (higher level). DMM can be used to represent models extracted from software written in most common object-oriented and procedural languages. This paper presents the main features of DMM.
This paper describes the key features of FAITH, a protocol independent test system for ISDN protocols. It is based on TTCN as test Nike Free Running Shoes Men Uk
notation and a test life cycle that is compliant with ISO9646. TTCN specifications are automatically compiled into executable code. FAITH supports the test specification, automatic test implementation, test execution, automatic test report generation of the test life cycle and additionally Air Presto
multi party testing methods and extensive test case selection techniques.
