Abstract

A three-dimensional (3D) numerical study has been performed to investigate the effects of non-gray gas radiation on double-diffusive natural convection in a cubic enclosure filled with either air–H2O or air–CO2mixtures in cooperating situations. Gas radiation was taken into account by the discrete ordinates method (DOM) associated with the spectral line weighted-sum-of-gray-gases (SLW) spectral model. Results obtained for two average concentrations of H2O and CO2(10% and 20%) show that radiation modifies the temperature and concentration structures by creating oblique stratifications. The heat transfer rate is decreased, whereas mass transfer is not much modified. In addition, a comparison between 2D and 3D results is presented. [ABSTRACT FROM AUTHOR]

43. Second-order balanced truncation

Author

UCL - FSA/INMA - Département d'ingénierie mathématique, Chahlaoui, Y., Lemonnier, D, Vandendorpe, A, Van Dooren, Paul, UCL - FSA/INMA - Département d'ingénierie mathématique, Chahlaoui, Y., Lemonnier, D, Vandendorpe, A, and Van Dooren, Paul

Abstract

We consider second-order linear time-invariant systems. The objective of this paper is to present a new method for constructing a reduced system by preserving the second-order structure of the original system. This new model reduction method uses a variant of the well-known balanced truncation technique applied to second-order gramians. We also compare it with another existing technique.

44. Balancing regular matrix pencils

Author

UCL - FSA/INMA - Département d'ingénierie mathématique, Lemonnier, D, Van Dooren, Paul, UCL - FSA/INMA - Département d'ingénierie mathématique, Lemonnier, D, and Van Dooren, Paul

Abstract

We present a new diagonal balancing technique for regular matrix pencils lambda B - A, which aims at reducing the sensitivity of the corresponding generalized eigenvalues. It is inspired by the balancing technique of a square matrix A and has a comparable complexity. The diagonally scaled pencil has row and column norms that are balanced in a precise sense. We also show that balancing a pencil boils down to making it closer to some standardized normal pencil. We give numerical examples illustrating that the sensitivity of generalized eigenvalues of a pencil may significantly improve after balancing.

Abstract

Summary OBJECTIVE We examined the gonadotrophin secretion in patients with increased plasma concentrations of testosterone and oestradiol due to hCG-producing tumours. DESIGN Comparison of plasma gonadotrophin concentrations before and after stimulation by GnRH, in eight men with hCG-producing tumours resulting in Increased testosterone and oestradiol plasma levels, and In 29 men with Leydig cell tumours resulting in increased oestradiol and normal to low testosterone plasma levels. PATIENTS Eight men with hCG-producing tumours (six with testicular tumours, two with extratesticular tumours), 29 men with Leydig cell tumours and 15 normal men. The six men with germinal cell tumours of the testis were studied before and after unilateral orchidectomy. MEASUREMENTS Plasma concentrations of hCG, testosterone and oestradiol were measured before and after intramuscular injection of hCG. LH and FSH were measured before and after intravenous Injection of 100 μg GnRH. RESULTS Plasma LH and FSH concentrations were low In patients with germ cell tumours, who exhibited increased plasma testosterone and oestradiol concentrations, and were normal in patients with Leydig cell tumours, in whom oestradiol only was increased. Plasma LH and FSH were normalized in the five patients with successful (e.g. normal hCG, testosterone and oestradiol) unilateral orchldectomy. Basal plasma testosterone concentrations correlated positively (P
