The connection between the Wigner function and the generalized OTF, and between the ambiguity function and the generalized OTF is investigated for non-paraxial scalar wavefields. The treatment is based on two-dimensional (2-D) wavefields for simplicity, but can be extended to the three-dimensional case.

In order to secure organizational sustainability in a rapidly changing environment, it is necessary to implement a decentralized and flexible work environment. In such work environments, normally individuals are provided with autonomy and independence in performing tasks, thus allowing them to further engage in their given work. This study investigated task antecedents of work engagement, and f...

Rizzo, House, and Lirtzman's (1970) Role Ambiguity Scale and Role Conflict Scales assess ambiguity with 6 negatively worded items and conflict with 8 positively worded items, respectively. This methodological confound between item wording and content precludes unambiguous interpretation. In the present study, confirmatory factor analysis of these 2 scales and Beehr, Walsh, and Taber's 0976) Rol...

This paper summaries our recent work on the application of the concepts of capacity per unit cost and reliability function per unit cost to models of fading channels. The cost is taken to be the energy, or a certain fourth moment functional that is sensitive to the bursti-ness of the signals, and is related to the ambiguity function of the input signal. The channel is assumed to be a Wide-Sense...

In the theory of integer least-squares ambiguity estimation and validation, a central role is played by the ambiguity search space. In this contribution, the significance of the volume of the ambiguity search space is discussed and analyzed. It is shown how the volume can be used as an estimate for the number of grid points inside the GPS ambiguity search space. This is done for various measure...

ambiguity, as one of the aesthetic tricks or techniques, makes the speech seem attractive, and the reader surprised. it looks pleasurable when its delay for accepting the meaning and its role in creating different meaning layers of speech is discovered. fifteen cases of ambiguity which results in development of the words’ meaning circle on the axis of companion, have been explained in present s...
