In this paper, the theory of information relationships and relationship measures is considered and its application to logic design is discussed. This theory makes operational the famous theory of partitions and set systems of Hartmanis. The information relationships and measures enable us to analyze relationships between the modeled information streams and constitute an important analysis appar...

The asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. The rigid disk is assumed to be in frictionless contact with the elastic half-space. By virtue of appropriate Green's functions, the mixed boundary value problem is written as a dual integral equation. Employing further mathematical tec...

We investigate bulge and disk scaling relations using a volume-corrected sample of earlyto intermediate-type disk galaxies in which, importantly, the biasing flux from additional nuclear components on the inner bulge light-profile has been modeled and removed. Structural parameters are obtained from a seeing-convolved, bulge+disk+nuclear-component decomposition applied to NIR surface brightness...

We present kinematic measurements of thin and thick disk components in a sample of nine edge-on galaxies. We extract stellar and ionized gas rotation curves at and above the galaxies’ midplanes using the Ca ii triplet absorption features and Hα emission lines measured with the GMOS spectrographs on Gemini North and South. For the higher mass galaxies in the sample, we fail to detect differences...

Many recently proposed BigData processing frameworks make programming easier, but typically expect the datasets to fit in the memory of either a single multicore machine or a cluster of multicore machines. When this assumption does not hold, these frameworks fail. We introduce the InfiniMem framework that enables size oblivious processing of large collections of objects that do not fit in memor...

We use a semi-empirical model to reproduce the 0.1–10μm spectral energy distribution (SED) of a sample of 85 luminous quasars. In the model, the continuum emission from the accretion disk as well as the nebular lines are represented by a single empirical template (disk), where differences in the optical spectral index are reproduced by varying the amount of extinction. The nearand mid-infrared ...

Suppose that a biconnected graph is given, consisting of large component plus several other smaller components, each separated from the main by separation pair. We investigate existence and computation time schematic representations structure such where drawn as disk, vertices take part in pairs are points on boundary small components placed outside disk represented non-intersecting lunes conne...

We present first results from a Keck/DEIMOS spectroscopic survey of red giant branch (RGB) stars in M33. The radial velocity distributions of the stars in our fields are well described by three Gaussian components, corresponding to a candidate halo component with an uncorrected radial velocity dispersion of σ ≃ 50 km s, a candidate disk component with a dispersion σ ≃ 16 km s, and a third compo...

HST has opened the possibility to decompose the surface brightness profiles of galaxies up to significant redshifts and look-back times into r− bulge and exponential disk components. This should allow to study the redshift evolution of bulge and disk luminosity contributions and discriminate between the different formation scenarios for these galaxy components currently discussed, i.e. decide i...
