The semiclassical Maxwell–Bloch equations beyond the slowly varying envelope approximation (SVEA) are derived in order to study the propagation of the ultrashort pulse in a two-level medium. The evolutions of the pulse shape, the group velocity and the pulse peak of 2[Formula: see text] ultrashort pulse are investigated as well as the pulse splitting of 4[Formula: see text] ultrashort pulse. By comparing the numerical results with those obtained using the SVEA, the error introduced by the approximation is quantitatively evaluated with respect to the pulse width and the applicable condition of the SVEA is discussed consequently. The envelope solutions presented by us allow clear observation on the evolution of the envelope.

This article shows the importance and value of ambiguity to reveal opportunities hidden in problems and the manner in which ambiguity is removed from applications of design thinking. It describes the value of introducing, sustaining, and using ambiguity and explains the different types of ambiguity. It follows up by describing the events when a designer encounters ambiguity. This article proposes that an understanding of ambiguity is needed to harness its capabilities in finding innovative opportunities. To do so, design practitioners should consider (1) identifying the type of ambiguity needed to expand the scope of opportunity exploration and (2) becoming aware of and managing one's ability to work with ambiguity. Finally, it identifies the lack of literature on the impact of independent and collective experience on using ambiguity in design.

Ambiguity is a common linguistic phenomenon and has attracted the attention of experts and scholars. From the communicative effect, ambiguity can be divided into intentional ambiguity and unintentional ambiguity. Unintentional ambiguity belongs to pragmatic failure, which influences the normal communication and need be disambiguated. However, Intentional ambiguity is a communication strategy for some particular communication purposes, which needn't be disambiguated and has a certain pragmatic value. The paper focuses on the positive use of intentional ambiguity in advertising, literary works, daily life, political speeches, etc.

This paper is an attempt to analyze the phenomenon of ambiguity from the perspective of communication effects. This paper divides ambiguity into intentional ambiguity and unintentional ambiguity, gives examples combined with communication teaching and forwards methods to avoid and eliminate ambiguity so as to help students clear obstacles to communication.

Based on the two-dimensional grey images of ambiguity functions of some simulated signals, the physical meaning of the ambiguity function cross-terms is explained in this paper. Then ambiguity function is used to analyze the vibration signals acquired from rolling bearings, and the analysis results are expressed in grey images. Finally the bearing fault diagnosis is accomplished by classifying the grey images of ambiguity functions. The experimental results show that, by classifying the grey images of ambiguity function including cross-terms, the kinds of the bearing defects can be identified effectively.

In this paper,the distinction and interrelation between ambiguity and fuzziness will be discussed.More attention has been paid in the methods of eliminating ambiguity and hedges in pragmatic fuzziness.My purpose is to indicate that fuzziness remains an underdeveloped area,but one that is important to explore.

It is standard to assume people making an uncertain choice experience no ambiguity when they know the probabilities that actually apply to the possible outcomes. However, bounded rationality, among other possible factors, may effectively create ambiguity in such cases. This chapter examines data from an experiment that allows us to compare decision behaviour under total ambiguity with that under 'no ambiguity'. The experimental evidence indicates people experience ambiguity even when none seems to be present, and the ambiguity biases decision behaviour in a systematic way. In particular, it makes prospects with an intermediate variance level particularly attractive, and it makes high variance prospects more attractive than they otherwise would be.

There exits ambiguity everywhere in English.This paper discusses several kinds of ambiguity in general at first,such as lexical ambiguity,structural ambiguity and pragmatic ambiguity.The paper further explains the effective way to avoid the ambiguity easily handicaping the language communication.Then,the paper focuses on the pragmatic ambiguity,hoping to avoid the improper ambiguity and conduct the language communication smoothly.
