Inspired by interfacial interactions of protein matrix and the crystal platelets in nacre, herein, a supertough artificial nacre was produced through constructing the synergistic interface interactions of p-p interaction and hydrogen bonding between graphene oxide (GO) nanosheets and sulfonated styreneethylene/butylene-styrene copolymer synthesized with multifunctional benzene. The resultant GO...

The capability to predict the reliability of complex systems that must be deployed without overly prolonged or expensive testing is of increasing importance to the military test and evaluation community. The presentation of subsystem reliability data to an artificial neural network is a critical factor in the capability of such networks to produce accurate system predictions. By producing a mat...

Solar fuel production through the so-called artificial photosynthesis has attracted a great deal of attention to development new world energy matrix that is renewable and environmentally friendly.

it is well known that the matrix exponential function has practical applications in engineering and applied sciences. in this paper, we present some new explicit identities to the exponential functions of a special class of matrices that are known as central-symmetric $x$-form. for instance, $e^{mathbf{a}t}$, $t^{mathbf{a}}$ and $a^{mathbf{a}t}$ will be evaluated by the new formulas in this par...

the purpose of this review article is to characterize all of the parameters regarding the types, polymers used, and release kinetics of matrix tablets. matrix system was the earliest oral extended release platform for medicinal use. matrix tablets are most commonly used methods to modulate the release profile of drugs. they are much desirable and preferred for such therapy because they offer be...

Artificial regressions are developed, based on elementary zero functions, that exploit the fact that the normal distribution is completely characterised by its first two moments. These artificial regressions can be used as the basis of numerical algorithms for the maximum likelihood estimation of models with normally distributed random elements, and other estimation techniques based on the opti...

Artificial Neural Networks technology has been applied to unfold the neutron spectra and to calculate the effective dose, the ambient equivalent dose, and the personal dose equivalent for Cf and AmBe neutron sources. A Bonner sphere spectrometry with a LiI(Eu) scintillator was utilized to measure the count rates of the spheres that were utilized as input in two artificial neural networks, one f...

PURPOSE Discomfort from light exposure leads to photophobia, glare, and poor vision in patients with congenital or trauma-induced iris damage. Commercial artificial iris lenses are static in nature to provide aesthetics without restoring the natural iris's dynamic response to light. A new photo-responsive artificial iris was therefore developed using a photochromic material with self-adaptive l...

Magnet filler-polymer matrix composites (Magpol) are an emerging class of morphing materials. Applications of Magpol can include artificial muscles, drug delivery, adaptive optics and self healing structures. Advantages of Magpol include remote contactless actuation, several actuation modes, high actuation strain and strain rate, self-sensing and quick response. The actuation modes of Magpol, i...

The necessary slack and surplus/artificial variables have already been added (and hence we have all constraints in the = form). Here, A is an m× n matrix (i.e., m rows and n columns), b is an m-vector, c and x are n-vectors. Thus, the n variables (represented as x) includes the slack/surplus/artificial variables. Suppose we know which of the n variables are basic in the optimal tableau. Since t...
