Construction of Column-Orthogonal Designs with Two-Dimensional Stratifications

open access: yesMathematics, 2023
For the design of computer experiments, column orthogonality and space-filling are two desirable properties. In this paper, we develop methods for constructing a new class of column-orthogonal designs (ODs) with two-dimensional stratifications on finer ...

Construction of tunable radial basis function networks using orthogonal forward selection

open access: yes, 2009
An orthogonal forward selection (OFS) algorithm based on leave-one-out (LOO) criteria is proposed for the construction of radial basis function (RBF) networks with tunable nodes.

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

open access: yesAdvanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

On existence and number of orthogonal arrays

open access: yesJournal of Combinatorial Theory, Series A, 1988
The authors show that for significantly large \(\lambda\) an orthogonal array \(A_ t(v,k,\lambda)\) exists for all (v,k,\(\lambda\),t) and that a signed orthogonal array \(SA_ t(v,k,t)\) exists for all (v,k,\(\lambda\),t), \(k\geq t\). As in \textit{N. M. Singhi} and \textit{S. S. Shrikhande} [A reciprocity relation for t-designs, Eur. J. Comb.

Rib Thickness Optimization of Vibration Test Fixture Based on Orthogonal Array for Weight Reduction

open access: yesMathematics
Vibration test fixtures are widely used to evaluate the dynamic characteristics of structures. However, their performance is often limited by their excessive weight and unintended resonances. Conventional optimization methods, such as genetic algorithms,

Dual‐band orthogonal polarised shared aperture array with shared‐elements

open access: yesElectronics Letters, 2021
In this paper, an orthogonal polarised dielectric resonator antenna (DRA) which can operate at S‐ and C‐band, has been designed as “shared‐element” for forming a dual‐band shared aperture array.

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Application of Taguchi Approache to Study the Effect of Filler Type on Tribological Behavior of Polymer Composite Under Dry Conditions [PDF]

open access: yesEngineering and Technology Journal, 2014
The tribological behaviour of a G-P ( glass-polyester ) composite system and G-P composite systems interfaced with graded fillers were tested. The composite materials of G-P and G-P reinforced with SiC and Graphite particles as secondary fillers were ...

A GENERAL THEORY FOR ORTHOGONAL ARRAY BASED LATIN HYPERCUBE SAMPLING

open access: yes, 2016
Orthogonal array based Latin hypercube sampling (LHS) is popularly adopted for computer experiments. Because of its stratification on multivariate margins in addition to univariate uniformity, the associated samples may provide better estimators for the ...

Invisible Polymer Walls Enhance Reorientational Optical Nonlinearity in Oligothiophene‐Doped Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
The polymer wall stabilized dye‐doped liquid crystals (PWLCs) enhance the sensitivity of photoinduced molecular reorientation in dye‐doped LC systems. The PWLC with an invisible polymer wall successfully reduces the threshold intensity and functions as an optical limiter under the incidence of low intensity light laser source.
