Abstract. We analyze VLBI delays back to 1984 from the permanent geodetic network, and ten superconducting gravimeter records from the Global Geodynamic Project spanning more than 7 years. From the former data, we deduce nutation offsets, and from the latter we get gravimetric factors. Comparison of these observed quantities against theoretical expressions of the core and mantle admittance to t...

The Single-Chip Cloud Computer (SCC) is an experimental many-core system created for research purposes by Intel Labs. In this paper, we analyze the necessary adjustments to run a Linux kernel on a processor core of the new processor design. Starting from the Intel-provided set of Linux modifications, we present an alternative strategy for creating a SCC-compliant kernel. Our approach allows to ...

There are more than twenty widely used e-indexes which are used to measure ICT Adoption all over the world. It might be a problem to choose ones to analyze the ICT dynamics or to compare the levels of ICT development in different regions of the world. So first the most common eindexes were reviewed. Then the comparative analysis of the e-indexes structure has been done. The coherence of the e-i...

We analyze a dielectric waveguide with a photonic crystal core. Using constant frequency contour analysis, we show that the modal behavior of this structure is drastically different from that of a conventional slab waveguide. In particular, at a given frequency the lowest-order guided mode can have an odd symmetry or can have more than one nodal plane in its field distribution. Also, there exis...

We extend the Landau theory of bent-core mesophases and d-wave high-Tc superconductors by considering additional secondary pseudo-proper order parameters. These systems exhibit a remarkable analogy relating their symmetry groups, lists of phases, and an infinite set of physical tensors. This analogy lies upon an internal dual structure shared by the two theories. We study the dual operator tran...

We present the first study of the Georgian blogosphere. The complete dataset on Georgian bloggers is collected and analyzed using Social Network Analysis tools. We identify the core-periphery structure present in the system. Results point to the fact that, after disregarding least important peripheral blogs that do not actively participate in the system, Georgian blogosphere is very compact. Th...

As librarianship evolves, it is important to examine the changes that have taken place in professional requirements. To provide an understanding of the current market demand for core competencies of librarianship, this article conducts a semi-automatic methodology to analyze job advertisements (ads) posted on the American Library Association (ALA) Joblist from 2009 through 2014. There is eviden...

We develop a Lattice Boltzmann code for computational fluid-dynamics and optimize it for massively parallel systems based on multi-core processors. Our code describes 2D multi-phase compressible flows. We analyze the performance bottlenecks that we find as we gradually expose a larger fraction of the available parallelism, and derive appropriate solutions. We obtain a sustained performance for ...

By numerically solving the nonlinear Schrodinger equation, we analyze pulse propagation through dispersion decreasing optical fibers (DDFs) in which the core radius varies along the length of the fiber; this in turn leads to a variation of dispersion as well as mode effective area along the length of the fiber. We calculate an optimum core radius profile required to create a local balance betwe...

PHASTA falls under the category of high-performance scientific computation codes designed for solving partial differential equations (PDEs). Its a massively parallel unstructured, implicit solver with particular emphasis on fluid dynamics (CFD) applications. More specifically, PHASTA is a parallel, hierarchic, adaptive, stabilized, transient analysis code that effectively employs advanced aniso...
