Preconditioning of Taylor models, implementation and test cases

Symbolic Preconditioning with Taylor Models: Some Examples

Deterministic global optimization with interval analysis involves − using interval enclosures for ranges of the constraints, objective, and gradient to reject infeasible regions, regions without global optima, and regions without critical points; − using interval Newton methods to converge on optimum-containing regions and to verify global optima. There are certain problems for which interval d...

Synthesizing Test Models from Test Cases

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

Implementation of Taylor Model Arithmetic

In the following, we describe in detail the current implementation of Taylor model arithmetic in version 8.1 of the code COSY INFINITY. Since in the Taylor model approach, the coefficients are floating point (FP) numbers, care must be taken that the inaccuracies of conventional FP arithmetic are properly accounted for. Algorithmically the methods are rather straightforward; however for practica...
