in the paper we establish some new results depending on thecomparative growth properties of composition of entire functionsusing relative $l^{ast }$-order (relative $l^{ast }$-lowerorder) as compared to their corresponding left and right factorswhere $lequiv lleft( rright) $ is a slowly changing function.

In a previous paper a method was developed to determine the shapes of dark matter halos of spiral galaxies from the flaring and velocity dispersion of the gas layer. Here I present the results for the almost edge-on Scd galaxy NGC 4244 and preliminary results for the Milky Way. NGC 4244’s dark matter halo is found to be highly flattened with a shortest-to-longest axis ratio of 0.2 −0.1 . If the...

This paper addresses the topic of online unsupervised speaker segmentation in a complex audio environment as it is present in the Broadcast News databases. A new two stage speaker change detection algorithm is proposed, which combines the Bayesian Information Criterion with an ABLS-SCD statistical framework where adapted Gaussian mixture models are used to achieve higher accuracy. To enhance th...

Differential Ks-band luminosity functions (LFs) are presented for a complete sample of 1613 nearby bright galaxies segregated by visible morphology. The LF for late-type spirals follows a power law that rises towards low luminosities whereas the LFs for ellipticals, lenticulars and bulge-dominated spirals are peaked and decline toward both higher and lower luminosities. Each morphological type ...

In a previous paper (Olling 1995) a method was developed to determine the shapes of dark matter halos of spiral galaxies from an accurate determination of the rotation curve, the flaring of the gas layer and the velocity dispersion in the H I . Here I report the results for the almost edge-on Scd galaxy NGC 4244 (Olling 1996a, 1996b). The observed flaring of the H I beyond the optical disk puts...

Taking a clue from the pair of HI supershells found in the Scd galaxy NGC 3556 (M 108), we propose a new mechanism for the origin of HI supershells in gas-rich massive galaxies. In this scenario, the two supershells were inflated out of the neutral hydrogen disk due to the localised flaring of a pair of radio lobes formed by the jets ejected from the nucleus during an active phase about ∼ 107 y...

We demonstrate the feasibility of uncovering supermassive black holes in late-type, “quiescent” spiral galaxies by detecting signs of very low-level nuclear activity. We use a combination of x-ray selection and multi-wavelength follow-up. Here, we apply this technique to NGC 3184 and NGC 5457, both of type Scd, and show that strong arguments can be made that both host AGNs.

Although sickling and solubility tests and peripheral blood film methods are today available for sickle cell disease screening in Uganda, their reliability and ease of applicability have not been determined. This study was therefore carried out to determine the reliability of sickling and solubility tests and peripheral blood film method for screening for SCD in Uganda. This was descriptive lab...

In a previous paper (Olling 1995, AJ, 110, 591) a method was developed to determine the shapes of dark matter halos of spiral galaxies from an accurate determination of the rotation curve, the flaring of the gas layer and the velocity dispersion in the H I . Here this method is applied to the almost edge-on Scd galaxy NGC 4244 for which the necessary parameters are determined in the accompanyin...
