OPTIMAL BUSINESS DECISION SYSTEM FOR MULTINATIONALS: A MULTIFACTOR ANALYSIS OF SELECTED MANUFACTURING FIRMS [PDF]
Traditional MIS has been made more effective through the integration of organization, human andtechnology factors into a decision matrix. The study is motivated by the need to find an optimal mixof interactive factors that will optimize the result of ...

CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Dependence of eigenvalues of 2mth-order spectral problems
A regular 2mth-order spectral problem with self-adjoint boundary conditions is considered in this paper. The continuous dependence of eigenvalues and normalized eigenfunctions on the problem is researched.

Controllability of Brain Neural Networks in Learning Disorders—A Geometric Approach
The human brain can be interpreted mathematically as a linear dynamical system that shifts through various cognitive regions promoting more or less complicated behaviors. The dynamics of brain neural network play a considerable role in cognitive function

Higher Eigenvalues of Graphs [PDF]
We present a general method for proving upper bounds on the eigenvalues of the graph Laplacian. In particular, we show that for any positive integer k, the k^{th} smallest eigenvalue of the Laplacian on a bounded-degree planar graph is O(k/n). This bound is asymptotically tight for every k, as it is easily seen to be achieved for planar grids.

Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

The Subdominant Eigenvalue of Möbius Monotone Transition Probability Matrix
We establish a Perron–Frobenius-type theorem for the subdominant eigenvalue of Möbius monotone transition matrices defined on partially ordered state spaces.

Let \(\lambda\) be an eigenvalue of a complex n by n matrix. Denote by m, \(m^*\) the multiplicity of \(\lambda\) as a root of the characteristic and minimal polynomial of the given matrix, respectively. Furthermore denote by \(\hat m\) the geometric multiplicity of \(\lambda\), i.e. the dimension of the corresponding eigenspace of \({\mathbb{C}}^ n\).

On graphs with just three distinct eigenvalues [PDF]
Let G be a connected non-bipartite graph with exactly three distinct eigenvalues Rho, mu, lambda, where Rho >mu >lambda. In the case that G has just one non-main eigenvalue, we find necessary and sufficient spectral conditions on a vertex-deleted ...

The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.
