Monotonicity of generalized Furuta type functions [PDF]
Operators and Matrices, 2012 The monotonicity of generalized Furuta type operator function Fs0 (r,s) =C −r 2 (C r 2 (A t 2 BpA t 2 )sC −r 2 ) (p+t)s0+r (p+t)s+r C −r 2 is discussed via the equivalent relations between operator inequalities. Let −1 t 0 . It is shown that, for each s0 such that t p+t < s0 , the function Fs0 (r,s) is decreasing for both r −t and s max{1,s0 ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

On Singular Generalized Absolutely Monotone Functions
Journal of Approximation Theory, 1994 Let \(\{u_ i\}^ \infty_{i=0}\) be an infinite sequence of functions belonging to \(C^ \infty [a,b]\), such that for all \(n\), \(n = 0,1, \dots, \{u_ i\}^ n_{\ell = 0}\) form an extended Chebyshev system on \([a,b]\). We assume that \(u_ i(t) = \varphi_ i (t;a)\), \(i = 0,1,2, \dots\), where \[ \varphi_ 0 (t;x) = \begin{cases} 0 & a \leq t < x \\ w_ 0 ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Spectral inequalities and G-functions [PDF]
, 1980 The results of Ostrowski on nonsingularity of matrices through diagonal dominance are generalized to the case of monotonic norms. From these results, combined with a basic theorem of Ky Fan, one obtains refinements and generalizations of the classical ...
