We describe a model for tree crown extraction from aerial images, a problem of great practical importance for the forestry industry. The novelty lies in the prior model of the region occupied by tree crowns in the image, which is a phase field version of the higher-order active contour inflection point ‘gas of circles’ model. The model combines the strengths of the inflection point model with t...

Pinker and colleagues propose two mechanisms - a rule system and a lexical memory - to form past tenses and other inflections. They predict that children's acquisition of the regular inflection is sudden; that the regular inflection applies uniformly regardless of phonological, semantic or other factors; and that the rule system is separably vulnerable to disruption. A connectionist account mak...

We present the new online edition of a dictionary of Polish inflection – the Grammatical Dictionary of Polish (http://sgjp.pl). The dictionary is interesting for several reasons: it is comprehensive (over 330,000 lexemes corresponding to almost 4,300,000 different textual words; 1116 handcrafted inflectional patterns), the inflection is presented in an explicit manner in the form of carefully d...

Using BCrier-techniques or B-spline-techniques for lntrrpolation or approximation of cur\es or wrfaces inflection pants or changes of sign of the Gaussian curvature occaaionallq occur. Inflection polnth or changer of sign of Gaussian curvature are ur&vwd in some applications. notably the fairlng of ship liner or the fairlng of car body surfaces. In the present contribution we mtroduce ~1 simple...

We report on an English-speaking, aphasic individual (TB) who showed a striking dissociation in speaking with the different forms (allomorphs) that an inflection can take. Although very accurate in producing the consonantal inflections (-/s/, -/z/, -/d/, -/t/), TB consistently omitted syllabic inflections (-/əz/, -/əd/), therefore correctly saying "dogs" or "walked," but "bench" for benches or ...

Children with specific language impairment (SLI) vary widely in their ability to use tense/agreement inflections depending on the type of language being acquired, a fact that current accounts of SLI have tried to explain. Finnish provides an important test case for these accounts because: (1) verbs in the first and second person permit null subjects whereas verbs in the third person do not; and...

This paper discusses the description of agrammatic production focusing on the verbal inflectional morphology. Agrammatism in Hebrew is investigated through an experiment with a patient who displays a highly selective impairment: agreement inflection is completely intact, but tense inflection, use of copula, and embedded structures are severely impaired. A retrospective examination of the litera...

This paper investigates the inflection-point instability that governs the flow disturbance initiated in the entrance region of a pulsating pipe flow. Under such a flow condition, the flow instability grows within a certain phase region in a pulsating cycle, during which the inflection point in the unsteady mean flow lifts away from the viscous effect-dominated region known as the Stokes layer. ...
