Distributed Network Tomography Applied to Stochastic Delay Profile Estimation [PDF]

Radioengineering, 2020
In this paper is shown, how delay properties of the edges of a network with stochastic properties can be estimated cooperatively by individual nodes that retain the delay profiles of the entire network. The proposed algorithm adopts null-space projection-

The Key Indicators of the Normality of Distribution

Inovacije u Nastavi, 2020
Statistics plays an important role in describing the results of various research. The basic role of statistical reasoning is to enable generalizations valid for the entire population to be made on the basis of certain quantitative characteristics of the ...

Tailored graph ensembles as proxies or null models for real networks I: tools for quantifying structure [PDF]

Journal of physics A: Mathematical and general, 2009
We study the tailoring of structured random graph ensembles to real networks, with the objective of generating precise and practical mathematical tools for quantifying and comparing network topologies macroscopically, beyond the level of degree ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Assignment and distributed control of laplacian null space in multiagent systems

International Journal of Control
The benchmark consensus protocol is used by the most notable distributed algorithms for controlling multiagent systems through local interaction rules, where it yields to the well-known Laplacian matrix whose null space is fixed and is spanned by the ...

Configuring Random Graph Models with Fixed Degree Sequences [PDF]

SIAM Review, 2016
Random graph null models have found widespread application in diverse research communities analyzing network datasets, including social, information, and economic networks, as well as food webs, protein-protein interactions, and neuronal networks.

Null and non–rainbow colorings of maximal planar graphs

Electronic Notes in Discrete Mathematics, 2013
Abstract For maximal planar graphs of order n ⩾ 4 , we prove that a vertex–coloring containing no rainbow faces uses at most ⌊ 2 n − 1 3 ⌋ colors, and this is best possible. The main ingredients in the proof are classical homological tools. By considering graphs as topological spaces, we introduce the notion of a null coloring,

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Positional graphs and conditional structure of weakly null sequences

Advances in Mathematics, 2013
We prove that, unless assuming additional set theoretical axioms, there are no reflexive space without unconditional sequences of density the continuum. We give for every integer $n$ there are normalized weakly-null sequences of length $\om_n$ without unconditional subsequences.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...
