Topological Graph Layouts into a Triangular Prism

Prism layouts are special cases of track layouts of graphs. A triangular prism layout for graphs is a graph layout into a triangular prism that carries the vertices along the three crests between two triangles of the prism and the edges in the three rectangular surfaces such that no two edges cross in the interior of the surfaces. Also, a topological prism layout for graphs is defined so that edges are allowed to cross the crests. As for topological prism layouts, it is desirable to have good bounds on the number of edge-crossings over crests for various classes of graphs. This paper constructs two-color-edge topological triangular prism layouts for complete bipartite graphs with fewer edge-crossings over the crests than previous results.

(d, 3)-track Layouts of Bipartite Graph Subdivisions

M. Miyauchi

Proc. of FIT (Forum on Information Technology) 2016, Part 1, pp. 5–10, Toyama, Japan, September 2016.

A (d, k)-track layout of a graph G consists of a k-track assignment of G and an edge d-coloring of G with no monochromatic X-crossing. This paper studies the problem of (d, 3)-track layout of bipartite graph subdivisions. As for track layout, V. Dujmović and D. R. Wood showed that every graph G with n vertices has a (d, 3)-track subdivision of G with 2⎡log_d qn(G)⎤+1 division vertices per edge, where qn(G) is the queue number of G. This paper improves their result for the case of bipartite graphs, and shows that for every integer d ≥ 2, every bipartite graph G_m,n has a (d, 3)-track subdivision of G_m,n with ⎡log_d n⎤−1 division vertices per edge, where m and n are the numbers of vertices of the partite sets of G_m,n with m ≥ n.

Linear Predictive Coding without Yule-Walker Approximation for Transient Signal Analysis – Application to Switching Noise

Proc. of CSPA 2017 (13th IEEE International Colloquium on Signal Processing & its Applications), pp. 46–50, Penang, Malaysia, March 2017.

We are investigating countermeasure techniques against electric noise on telecommunication and related equipment. There are many types of electric noise, and we focus on the characterization of transient noise such as the switching noise of switching power supplies. We are developing a method of transient signal analysis based on linear predictive coding (LPC) for the purpose. Unfortunately, as standard LPC contains Yule-Walker (YW) approximation, which replaces a given time series with a periodic time series for simplification, it is not suitable for transient signal analysis. Therefore, our method of transient signal analysis does not contain YW approximation. Instead, we use the local linearization technique, which was developed in the field of quantum mechanics. Our method makes it possible to obtain instantaneous frequencies and instantaneous decay rates simultaneously with high precision from a small number of samples. We discuss our LPC method avoiding the use of YW approximation and using the local linearization technique and its application to repetitive ringing signals, which mimics the switching noise of a switching power supply, to show the efficiency of our method.

360-degree Screen-free Floating 3D Image in a Crystal Ball Using a Spatially Imaged Iris and Rotational Multiview DFD Technologies

A rotational multiview depth-fused 3D (DFD) display and 360-deg displaying optics using a spatially imaged iris method are proposed to realize a 360-deg 3D image. This method enables displaying clear floating images in a crystal ball. Its symmetric optics provide clear and natural 360-deg images with smooth motion parallax in horizontal and vertical directions using the directional selectivity of a spatially imaged iris method and natural 3D images of a rotational multiview DFD display.
