a common method to determine the order of minimal realization of a continuous linear time invariant descriptor system is to decompose it into slow and fast subsystems using the weierstrass canonical form. the weierstrass decomposition should be avoided because it is generally an ill-conditioned problem that requires many complex calculations especially for high-dimensional systems. the present ...

Design of optimal microstructures for infiltrated solid oxide fuel cell (SOFC) electrodes is a complicated process because of the multitude of the electrochemical and physical phenomena taking place in the electrodes in different temperatures, current densities and reactant flow rates. In this study, a stochastic geometric modeling method is used to create a range of digitally realized infi...

the realization optimality theory is a recent development in the original optimality theory which is proposed to deal with morphological issues especially the inflectional ones. its main idea is to consider the morphological realization rules as ranked violable language-specific constraints that control the realization processes and provide phonological information of grammatical morphemes. thi...

fatigue behavior of a vanadium microalloy steel has been studied in this research. here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. the results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. optimal heat treatment cycle of the microalloyed stee...

Background:Hospitalization of the newborn infant can cause depression crisis and severely undermine the attainment and realization of maternal role in a primipara. The neonate’s maternal grandmother can provide the support needed to help the primipara avoid or overcome the ensuing problems. Aim: This study aimed to investigate the effect of empowerment of grandmothers on depression and maternal...

We study the corrections to the determination of sin(2β) from the time dependent CP asymmetry of B → J/ΨKS which arise in the standard model. Although a precise prediction of these corrections is not possible we find that they are indeed extremely small, of the order of less than a per mil of the observed value. This means in turn that any deviation visible at the B factories will be a clear si...

Subspace identification techniques are reinterpreted via classical realization theory to formulate a wide class of subspace identification methods. Re-formulating subspace identification in terms of a low rank decomposition of a weighted Hankel matrix allows special cases such as impulse-based and step-based input signals, but also realization based on arbitrary input signals and correlation fu...

Several intersection graphs such as curves-in-the-plane graphs, circular-arc graphs, chordal graphs and interval graphs are reviewed, especially on their recognition algorithms. In this connection graph realization problem is mentioned.

in this study, the changes in microstructure of hp-nb cast heat resistant steel after 8 years of service at high temperatures were investigated. study of microstructure using optical microscopy (om) and scanning electron microscopy (sem) equipped with an energy dispersive spectrometry (eds) showed that the microstructure of this steel in as-cast condition includes an austenitic matrix, and that...

in responses to norheim’s editorial, this commentary offers reflections from thailand, how the five unacceptable trade-offs were applied to the universal health coverage (uhc) reforms between 1975 and 2002 when the whole 64 million people were covered by one of the three public health insurance systems. this commentary aims to generate global discussions on how best uhc can be gradually achieve...
