This paper presents a new idea of modeling onedimensional dynamic systems by higher-order ordinary differential equation (HODE) models in stead of by the ARMA models used in the traditional time series analysis. Accordingly, based on the idea of hybrid evolutionary modeling, we modify the HEMA algorithm in (Cao et al., 1998a; Cao et al., 1998b) to approach the modeling problem of HODEs for dyna...
Industrial coal combustion ashes as well as laboratory-scale experiments were used for the evaluation whether CaO, Al2O3 and Fe2O3 can help with the retention of volatile and acid-forming elements (S, Cl, Br, As and Se). Both industrial ashes evaluation and laboratory combustion experiments lead to the conclusion that CaO can efficiently help with the capture of not only S, but also of Cl, Br, ...
In this study, the effect of two types of SiC powders consist of SiC-1 (β-SiC) and SiC-2 (β-SiC+α-SiC) and also different values of CaO additive consist of 0, 0.4 and 0.8 weight percent on sintering behavior of sintered SiC with pressureless technique in Al2O3-Y2O3-CaO additive system was investigated. In all specimens, Al2O3:Y2O3 molar ratio was equal to 3:2 and all amounts of additive were e...
Homogeneous matrices of calcium oxide (CaO) were prepared by mixing this material with polyethylene glycol (PEG) acting as malleable inert support in order to obtain processable composites. Preliminary tests were carried out to assess the best concentration of CaO in the composite, individuated in the CaO/PEG weight ratio of 1/4. Experimental data highlighted that the composite was able to sele...

In this paper we present CAOVerif, a deductive verification tool for the CAO language. CAO is a domain-specific language for cryptography with interesting challenges for formal verification. It introduces not only a rich mathematical type system, but it also offers cryptography-oriented language constructions. The toolchain encompasses different transformations of the source code in order to ge...
Die teilflächendifferenzierte Kenntnis von Bodengruppe und pH-Wert in Kombination mit einer teilflächendifferenzierten CaO-Applikation entspricht einer konsequent standortangepassten Kalkung sie führte bei annähernd gleichem CaO-Aufwand zu einem mittleren Mehrgewinn gegenüber der ganzflächig einheitlichen Bewirtschaftung von 34 €/ha/Jahr. Deutlich geringer (13 €/ha/Jahr) fällt dieser Mehrgewinn...
High-pressure melting experiments on the Homestead L5 ordinary chondrite were performed at 5 GPa in a multi-anvil device over a temperature interval that ranged from near solidus to near liquidus conditions. Near solidus silicate liquids of Homestead have higher CaO/Al2O3 and lower Mg# compared to solidus liquids of terrestrial peridotite (e.g.: KLB-1) at this pressure. The silicate portion of ...
Experimental and clinical evidence indicates that high risk for sudden death is significantly correlated with post-myocardial infarction depression in two "markers" of vagal activity, heart rate variability and baroreflex sensitivity. The present experiments were designed to answer some of the questions generated by those findings. In 33 anesthetized cats, the neural activity of single cardiac ...
