Kinetic study of static recrystallization in an Fe–Al–O ultra-fine-grained nanocomposite

A nearly abrupt coarsening of grains is observed in a newly developed Fe–Al–O ultra-fine-grained nanocomposite with a significant volume fraction (4%) of alumina nano-precipitates. The microstructure of the alloy was analysed in different states (as-received and annealed) by means of scanning electron microscopy, transmission electron microscopy (TEM) and hardness. The initial grain size 150–200 nm increases up to 50 μm during annealing 1000 °C/8 h and thereafter demonstrates saturation. A linear correlation between volume fraction of coarse grains and hardness was found. It was identified by TEM that alumina nano-precipitates stabilize the dislocation microstructure against recovery very effectively and the grain coarsening is due to fast growth of very few dislocation free grains. Thus, the observed grain coarsening has the attributes of static recrystallization.

A note on the normal form of closed formulas of interpretability logic

Each closed (i.e. variable free) formula of interpretability logic is equivalent in ILF to a closed formula of the provability logic G, thus to a Boolean combination of formulas of the form ⁿ.     

Informational approach to the processing of inflected morphology: Standard data reconsidered

Summary The present paper evaluates the two standard approaches to the processing of inflected morphology (decomposition and the satellite-entries hypothesis) in the scope of the results obtained on Serbo-Croatian inflected noun forms. It was demonstrated that the decomposition hypothesis cannot account for most of the results. On the other hand, some of the critical experiments upon which the satellite-entries hypothesis was based failed to replicate, and the hypothesis was rejected on empirical grounds. The approach proposed in the present study assumes that processing effects observed with inflected Serbo-Croatian noun forms are based on the subject's sensitivity to the amount of information (i. e., bits) within a particular inflected form. It was demonstrated that the basic unit of the subject's sensitivity is the amount of information derived from the average frequency per syntactic function within a particular inflected form of a noun. This parameter accounts for all the observed processing variability of the inflected Serbo-Croatian noun forms.

Processing differences between nouns,adjectives, and verbs

Summary Processing differences were investigated for nouns, adjectives, and verbs in Serbocroatian, a language that depends strongly on inflection to convey grammatical information. Four lexical decision experiments were run. Two of them inspected processing of inflected forms of nouns, demonstrating analogous processing for both singular and plural forms. Processing of the nominative case was faster for both grammatical numbers. Reaction times for the various case forms were not related to their respective frequencies of occurrence. Adjectival processing, on the other hand, gave no privileged role to the nominative case and the inflected form frequency had a strong influence. Similarly, verbs also showed frequency-based processing. An explanation was proposed, suggesting that the organization of inflectional processing is dependent on the number of inflectional alternatives available to a given word.This research was supported by National Institute of Health (USA) grants HD-08495 to the University of Belgrade and HD-01994 to the Haskins Laboratories.     

Identification of partially presented meaningless patterns: effect of completeness and distinctiveness

The role of parts versus that of wholes in a visual perception has been debated for a century as two opposite approaches, namely, an analytic and holistic. In two psychophysical experiments we investigated whether the stimulus completeness or distinctiveness is essential for identification of the partially presented patterns under brief presentation conditions. For this purpose, a special class of stimuli was constructed in such a way that the patterns could be divided into informative and redundant parts. The first experiment clearly demonstrated the importance of the redundant part for effective pattern identification for the majority of subjects. The second experiment revealed the direct dependence of identification accuracy of the patterns on their completeness (2, 3, 4, 5, or 6 elements). Familiarisation of subjects with the test stimuli influenced the strength of this dependence.
