Multiple Power-Saving MSSs Scheduling Methods for IEEE802.16e Broadband Wireless Networks

open access: yesThe Scientific World Journal, 2014
This work proposes two enhanced multiple mobile subscriber stations (MSSs) power-saving scheduling methods for IEEE802.16e broadband wireless networks. The proposed methods are designed for the Unsolicited Grant Service (UGS) of IEEE802.16e.

On Some Distance Spectral Characteristics of Trees

open access: yesAxioms
Graham and Pollack in 1971 presented applications of eigenvalues of the distance matrix in addressing problems in data communication systems. Spectral graph theory employs tools from linear algebra to retrieve the properties of a graph from the spectrum ...

Interlacing of zeros of weakly holomorphic modular forms

open access: yesProceedings of the American Mathematical Society, Series B, 2014
We prove that the zeros of a family of extremal modular forms interlace, settling a question of Nozaki. Additionally, we show that the zeros of almost all forms in a basis for the space of weakly holomorphic modular forms of

A generalization of the Heine--Stieltjes theorem

open access: yes, 2009
We extend the Heine-Stieltjes Theorem to concern all (non-degenerate) differential operators preserving the property of having only real zeros. This solves a conjecture of B. Shapiro.

Spectral Results on Some Hamiltonian Properties of Graphs [PDF]

open access: yesRomanian Journal of Mathematics and Computer Science, 2014
Using Lotker’s interlacing theorem on the Laplacian eigenvalues of a graph in [5] and Wang and Belardo’s interlacing theorem on the signless Laplacian eigenvalues of a graph in [6], we in this note obtain spectral conditions for some Hamiltonian ...

The Visibility of Temporal Artifacts in Stereo 3D Displays

open access: yesi-Perception, 2012
The temporal protocols used in stereoscopic 3D (S3D) displays have many parameters that affect the visibility of temporal artifacts. Flicker is visible at low presentation rates.

Interlacing Results for Hypergraphs [PDF]

open access: yesProceedings of Blockchain in Kyoto 2021 (BCK21), 2021
Hypergraphs are a generalization of graphs in which edges can connect any number of vertices. They allow the modeling of complex networks with higher-order interactions, and their spectral theory studies the qualitative properties that can be inferred from the spectrum, i.e. the multiset of the eigenvalues, of an operator associated to a hypergraph. It
