in this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent hamiltonians. we drive the time-dependent recursion relations for the renormalized tight-binding hamiltonian by decimating selective sites of lattice iteratively. the formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

In this brief paper we justify observations made in El Naschie's paper " On the Unification of the Fundamental Forces... " , on the Planck scale, fractal space time and the unification of interactions, from different standpoints. In a recent paper El Naschie[1] has emphasized the intimate connection between the Planck length, the Compton wavelength and a unification of the fundamental interacti...

The original ideas about noncommuting coordinates are recalled. The connection between U(1) gauge fields defined on noncommuting coordinates and fluid mechanics is explained. Non-Abelian fluid mechanics is described. I The idea that configuration-space coordinates may not commute,

background and aims: one of the most common approach to understanding spatial and temporal trends of event data is to break it up into a series of time snapshots. therefore space-time cube method applied in order to portray the likely trend in occurrence of the pulmonary tuberculosis (tb) cases. methods: in this study, information of all patients with pulmonary tb recorded in surveillance syste...

We present a new model for creating composite visualizations of multidimensional datasets using simple visual representations such as point charts, scatterplots, and parallel coordinates as components. Each visual representation is contained in a tile, and the tiles are arranged in a mosaic of views using a space-filling slice-and-dice layout. Tiles can be created, resized, split, or merged usi...

In this paper, we propose a new method for interactive motion control with a multi-touch interface. A user of our system can touch and drag character’s body parts to control its motion. The character’s full body motion is driven by our interactive motion control model based on the movement of a few body parts which are directly manipulated by the user via the multi-touch interface. We propose a...

We describe G-Space (Geodesic Space), a straightforward linear time layout algorithm that draws undirected graphs based purely on their topological features. The algorithm is divided into two phases. The first phase is an embedding of the graph into a 2-D plane using geodesic distances as coordinates. These coordinates are computed with the same process used by HDE (High-Dimensional Embedding) ...

The solid map provides a view-independent method for solid texturing using an ordinary 2-D surface texture map. The solid map transforms a model’s polygons into 2-D texture space without overlap. It then rasterizes the polygons in this space, interpolating the solid texture coordinates across the pixels of the polygon. These stored solid texture coordinates are then read by a texture synthesis ...

Periods of parallel exterior forms define natural coordinates on the deformation space of complete affine structures on the two-torus. These coordinates define a differentiable structure on this deformation space, under which it is diffeomorphic to R 2. The action of the mapping class group of T 2 is equivalent in these coordinates with the standard linear action of SL(2, Z) on R 2 .

Given a set S of n points in the plane, we consider the problem of answering range selection queries on S: that is, given an arbitrary x-range Q and an integer k > 0, return the k-th smallest y-coordinate from the set of points that have x-coordinates in Q. We present a linear space data structure that maintains a dynamic set of n points in the plane with real coordinates, and supports range se...
