Selected AbstractsMechanisms of Visual Object Recognition in Infancy: Five-Month-Olds Generalize Beyond the Interpolation of Familiar ViewsINFANCY, Issue 1 2007Clay Mash This work examined predictions of the interpolation of familiar views (IFV) account of object recognition performance in 5-month-olds. Infants were familiarized to an object either from a single viewpoint or from multiple viewpoints varying in rotation around a single axis. Object recognition was then tested in both conditions with the same object rotated around a novel axis. Infants in the multiple-views condition recognized the object, whereas infants in the single-view condition provided no evidence for recognition. Under the same 2 familiarization conditions, infants in a 2nd experiment treated as novel an object that differed in only 1 component from the familiar object. Infants' object recognition is enhanced by experience with multiple views, even when that experience is around an orthogonal axis of rotation, and infants are sensitive to even subtle shape differences between components of similar objects. In general, infants' performance does not accord with the predictions of the IFV model of object recognition. These findings motivate the extension of future research and theory beyond the limits of strictly interpolative mechanisms. [source] The correlation problem in sensor fusion in a possibilistic frameworkINTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 11 2001Michel Grabisch This paper addresses the correlation problem which is central in sensor fusion, from the viewpoint of possibility theory. This problem aims at separating pieces of information pertaining to different objects and to gather those which are likely to pertain to the same object. We present two different views of the problem, one based on similarity relations, while the other discusses the problem in a logical framework. © 2001 John Wiley & Sons, Inc. [source] The malleable bicultural consumer: effects of cultural contexts on aesthetic judgmentsJOURNAL OF CONSUMER BEHAVIOUR, Issue 1 2010Veena Chattaraman Grounded in the cognitive framework of processing fluency, this study proposes further support for the experiential perspective in aesthetics by positing that aesthetic response to the same object may be malleable, depending on how the symbolic properties of the object interact with different cultural contexts which either facilitate or debilitate the processing experience of the perceiver. The study employed an Internet experiment to test the hypotheses among 105 female Hispanic college-aged students enrolled at a large midwestern university. The findings revealed that symbolic attributes of products interact with cultural contexts to affect aesthetic judgments of (Hispanic) consumers. Aesthetic judgments were more positive when evaluating culturally symbolic product attributes after exposure to congruent contextual cues that facilitate fluent processing. The study furnishes support for the impact of environment/context on consumer behavior and aesthetic judgment, thus establishing further support for the cognitive framework of conceptual fluency in explaining aesthetic response. The study also contributes to recent literature on "frame-switching" among bicultural consumers by suggesting that these consumers navigate between competing cultural frames in response to visual primes, with resultant shifts in aesthetic judgments. Important marketing insights emerge from these findings. Copyright © 2009 John Wiley & Sons, Ltd. [source] Measurement System Analysis for Bounded Ordinal DataQUALITY AND RELIABILITY ENGINEERING INTERNATIONAL, Issue 5 2004Jeroen de Mast Abstract The precision of a measurement system is the consistency across multiple measurements of the same object. This paper studies the evaluation of the precision of measurement systems that measure on a bounded ordinal scale. A bounded ordinal scale consists of a finite number of categories that have a specific order. Based on an inventory of methods for the evaluation of precision for other types of measurement scales, the article proposes two approaches. The first approach is based on a latent variable model and is a variant of the intraclass correlation method. The second approach is a non-parametric approach, the results of which are, however, rather difficult to interpret. The approaches are illustrated with an artificial data set and an industrial data set. Copyright © 2004 John Wiley & Sons, Ltd. [source] Beyond flat weals: validation of a three-dimensional imaging technology that will improve skin allergy researchCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 6 2008R. V. Dos Santos Summary Skin-prick tests (SPTs) are a standard way to test for sensitizations to allergens, but to date, techniques that allow for high-quality measurements of the resulting weals for research purposes are lacking. In this study, we assessed a new three-dimensional (3D) imaging technology for its accuracy and consistency. We found that this new technology showed very little intraoperator and interoperator variation for repeated measurements of a model of known area by each of two operators. We also found that repeated measurements of the same object over 4 months showed virtually no variation. Finally, 3D imaging was superior to traditional ruler measurements for assessing SPT reactions to histamine and allergen. For high-quality measurements of SPT reactions, 3D imaging is accurate, consistent and reliable. [source] Toddlers can adaptively change how they categorize: same objects, same session, two different categorical distinctionsDEVELOPMENTAL SCIENCE, Issue 1 2009Jessica S. Horst Two experiments demonstrate that 14- to 18-month-old toddlers can adaptively change how they categorize a set of objects within a single session, and that this ability is related to vocabulary size. In both experiments, toddlers were presented with a sequential touching task with objects that could be categorized either according to some perceptually salient dimension corresponding to a taxonomic distinction (e.g. animals vs. vehicles) or to some less obvious dimension (e.g. rigid vs. deformable). In each experiment, children with larger productive vocabularies responded to both dimensions, showing evidence of sensitivity to each way of categorizing the items. Children with smaller productive vocabularies attended only to the taxonomically related categorical grouping. These experiments confirm that toddlers can adaptively shift the basis of their categorization and highlight the dynamic interaction between the child and the current task in early categorization. [source] The origins and evolution of links between word learning and conceptual organization: new evidence from 11-month-oldsDEVELOPMENTAL SCIENCE, Issue 2 2003Sandra Waxman How do infants map words to their meaning? How do they discover that different types of words (e.g. noun, adjective) refer to different aspects of the same objects (e.g. category, property)? We have proposed that (1) infants begin with a broad expectation that novel open-class words (both nouns and adjectives) highlight commonalities (both category- and property-based) among objects, and that (2) this initial expectation is subsequently fine-tuned through linguistic experience. We examine the first part of this proposal, asking whether 11-month-old infants can construe the very same set of objects (e.g. four purple animals) either as members of an object category (e.g. animals) or as embodying a salient object property (e.g. four purple things), and whether naming (with count nouns vs. adjectives) differentially influences their construals. Results support the proposal. Infants treated novel nouns and adjectives identically, mapping both types of words to both category- and property-based commonalities among objects. [source] Koopman-von Neumann formulation of classical Yang-Mills theories: IANNALEN DER PHYSIK, Issue 3 2006P. Carta Abstract In this paper we present the Koopman-von Neumann (KvN) formulation of classical non-Abelian gauge field theories. In particular we shall explore the functional (or classical path integral) counterpart of the KvN method. In the quantum path integral quantization of Yang-Mills theories concepts like gauge-fixing and Faddeev-Popov determinant appear in a quite natural way. We will prove that these same objects are needed also in this classical path integral formulation for Yang-Mills theories. We shall also explore the classical path integral counterpart of the BFV formalism and build all the associated universal and gauge charges. These last are quite different from the analog quantum ones and we shall show the relation between the two. This paper lays the foundation of this formalism which, due to the many auxiliary fields present, is rather heavy. Applications to specific topics outlined in the paper will appear in later publications.

Das Alterungsverhalten und die Lebensdauer von Fassadensystemen wird stark von der hygrothermischen Beanspruchung beeinflußt. Neben den Witterungsbedingungen Temperatur, Strahlung und Luftfeuchte wirken häufig auch noch äußere oder innere Feuchtequellen, z. B. Schlagregen, Baufeuchte oder Oberflächenbetauung auf Außenwände ein. Wegen ihrer geringen Masse sind Wärmedämm-Verbundsysteme (WDVS) davon z. T. besonders betroffen. Dennoch zeigt die Langzeitstudie an Objekten mit WDVS, daß damit keine erhöhte Schadensanfälligkeit verbunden ist. Abgesehen von einigen optischen Mängeln ist das Langzeitverhalten von WDVS als sehr positiv zu bewerten. Bei regelmäßiger Wartung entspricht die Lebensdauer von WDVS der von herkömmlich verputzten Außenwänden. (© 2006 WILEY-VCH Verlag GmbH & Co.

Apart from the fluctuating climatic conditions temperature, solar radiation and humidity there are often additional exterior or interior sources of moisture, e.g. driving rain, construction moisture or surface condensation acting on facades. External wall insulation systems (ETICS = E xternal T hermal I nsulation C omposite S ystems) are especially affected due to their low mass. However, the long-term observation by repeated inspections of the same objects over a period of 30 years proves that ETICS show not more damage than traditional facades. Apart from minor esthetical problems due to soiling or microbial growth their long-term behaviour is very encouraging. Maintained at normal intervals ETICS are as durable as traditionally rendered masonry walls. [source] | |||||||||||||
