By using the fractional Fourier transformation of the time-domain signals, closed-form expressions for the projections of their auto or cross ambiguity functions are derived. Based on a similar formulation for the projections of the auto and cross Wigner distributions and the well known two-dimensional (2-D) Fourier transformation relationship between the ambiguity and Wigner domains, closed-fo...

Al-Najjar and Weinstein 2009 propose to scrutinize the implications of recent theories of ambiguity in dynamic settings. They conclude that such implications are so unreasonable as to cast doubts on the legitimacy of the theories under consideration. The present paper argues that the seemingly unreasonable implications highlighted by Al-Najjar and Weinstein can be understood as the result of ba...

ln this paper, we describe an approach to planning sensing slralegies dynamically, based on the system’s current best information about the world. Our approach is for the system to automatically propose a sensing operation, and then to determine the maximum ambiguity which might remain in the world description if that sensing operation were applied. The system then applies that sensing operatio...

We present the concept of nocuous ambiguity, which occurs when text is interpreted differently by different readers. In contrast, text exhibits innocuous ambiguity if different readers interpret it in the same way, even though structural or semantic analyses suggest that multiple interpretations may be possible. We collect multiple human judgements of a set of English phrases obtained from requ...

We analyze a market populated by expected utility maximizers and smooth ambiguity-averse consumers. We study conditions under which ambiguity-averse consumers survive and affect prices in the limit. If ambiguity vanishes with time or if the economy exhibits no aggregate risk, ambiguity-averse consumers survive, but have no long-run impact on prices. In both scenarios, ambiguity-averse consumers...

A major point of debate about morally good motives concerns an ambiguity in the truism that and strong-willed people desire to do what is right. This shaped by assumption “what’s right” combines only two ways with “desire,” leading distinct de dicto re readings truism. However, a third reading such expressions possible, first identified Janet Fodor, which has gone wholly unappreciated philosoph...

This study compared the rate of literacy acquisition in orthographically transparent Welsh and orthographically opaque English using reading tests that were equated for frequency of written exposure. Year 2 English-educated monolingual children were compared with Welsh-educated bilingual children, matched for reading instruction, background, locale, and math ability. Welsh children were able to...

Many noun phrases in text are ambiguously quantified: syntax doesn't explicitly tell us whether they refer to a single entity or to several and, in main clauses, what portion of the set denoted by the subject Nbar actually takes part in the event expressed by the verb. For instance, when we utter the sentence Cats are mammals, it is only world knowledge that allows our hearer to infer that we m...

Purpose This paper presents a systematic literature review aiming at analysing how research has addressed performance measurement systems’ (PMSs) ambiguities in the public sector. embraces ambiguity perspective that PMSs sector coexist with and cope existing ambiguities. Design/methodology/approach The authors conducted Scopus ScienceDirect, considering articles published since 1985, selected j...
