Determination of the Equivalent Thickness of a Taiko Wafer Using ANSYS Finite Element Analysis

open access: yesApplied Sciences, 2023
The successful handling of large semiconductor wafers is crucial for scaling up their production. Early-stage warpage control allows the prevention of undesirable asymmetric warpage, known as wafer bifurcation or buckling.

On the Number of Balanced Words of Given Length and Height over a Two-Letter Alphabet [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2010
We exhibit a recurrence on the number of discrete line segments joining two integer points in the plane using an encoding of such segments as balanced words of given length and height over the two-letter alphabet $\{0,1\}$.

Time-stage driven pathfinding framework for optimized medical treatments

open access: yesCogent Engineering, 2023
Coming up with the correct patient-specific treatment procedure is a non-trivial task. One of the main challenges is that the problem is combinatorial, and each treatment can be followed by numerous treatments.

$L^p$-$L^q$ Boundedness of Spectral Multipliers of the Anharmonic Oscillator

open access: yesComptes Rendus. Mathématique, 2022
In this note we study the $L^p-L^q$ boundedness of Fourier multipliers of anharmonic oscillators, and as a consequence also of spectral multipliers, for the range ...

Decomposing 10-Regular Graphs into Paths of Length 5

open access: yesDiscussiones Mathematicae Graph Theory, 2022
Let G be a 10-regular graph which does not contain any 4-cycles. In this paper, we prove that G can be decomposed into paths of length 5, such that every vertex is a terminal of exactly two paths.

An Improved Simulated Annealing Algorithm With Excessive Length Penalty for Fixed-Outline Floorplanning

open access: yesIEEE Access, 2020
In addition to wirelength and area, modern floorplans need to consider various constraints such as fixed-outline. To handle the fixed-outline floorplanning optimization problem efficiently, we propose an improved simulated annealing (SA) algorithm, which

Tropical Oriented Matroids [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
Tropical oriented matroids were defined by Ardila and Develin in 2007. They are a tropical analogue of classical oriented matroids in the sense that they encode the properties of the types of points in an arrangement of tropical hyperplanes – in much the

The extremal graphs with respect to their nullity

open access: yesJournal of Inequalities and Applications, 2016
The nullity of a graph G, denoted by η ( G ) $\eta(G)$ , is the multiplicity of the eigenvalue zero of its adjacency matrix. In this paper, we determine all graphs with η ( G ) = n ( G ) − 2 m ( G ) − c ( G ) $\eta(G)=n(G) - 2m(G) -c(G)$ , where c ( G ) =

Bicyclic graphs with maximum sum of the two largest Laplacian eigenvalues

open access: yesJournal of Inequalities and Applications, 2016
Let G be a simple connected graph and S 2 ( G ) $S_{2}(G)$ be the sum of the two largest Laplacian eigenvalues of G. In this paper, we determine the bicyclic graph with maximum S 2 ( G ) $S_{2}(G)$ among all bicyclic graphs of order n, which confirms the
