burnout syndrome includes aspects of emotional exhaustion, depersonalization and decrement of personal accomplishment to which staffs vulnerable to because of their exposure to physical and psychological stressors. the necessity of this research is related to inadequate research on women. the current research aims to explain burnout of working women with an emphasis on the role of organizationa...

Under the traditional method of frequent trajectory mining, the location of data is obtained through the GPS device. However, limited equipment accuracy may incur location ambiguity. In this paper, we propose a new trajectory data clustering method based on dynamic grid density, in order to remove this ambiguity. In this method, the trajectory space of an object is firstly divided into equal-si...

A coherent optical processor for displaying a signal's ambiguity function is described. The required time delay is realized by 45 degrees rotations of two identical input transparencies and the Doppler shift by a 1-D Fourier transformation. The entire ambiguity function is displayed in the output (Doppler shift-time delay) plane. Examples of the optically computed ambiguity function for single ...

This paper presents an implemented, computationally inexpensive technique for disambiguating categories (parts of speech) by exploiting constraints on possible category combinations. Early resolutions of category ambiguities provide a great deal of leverage, simplifying later resolutions of other types of lexical ambiguity. Prioritized pattern action rules (CONDS) are specified for each known c...

A simple algorithm based on discrete chirp Fourier transform (DCFT) is used for the chirp signal parameters estimation in impulse noise environments. A modification of the DCFT is introduced in order to produce accurate estimates in this case. This modification, called the robust DCFT, produces highly accurate results in impulse noise environments, while for the Gaussian noise it is only slight...

In this work we propose a novel ap roach for demodulating Continuous Phase Modulation CPM) signals based Q on the modeling of the instantaneous phase as a piecewise polynomial-phase function. The polynomial modeling can be a good approximation for currently used modulations or it can be-exact if the shaping pulse is chosen to be a oiecewise polvnomial function. The crucial step in the demodulat...

We propose an acoustic feature for speech recognition based on the combination of MFCC and fractional Fourier transform (FrFT). Since the transform order is critical for the performance of FrFT, we use the ambiguity function to adaptively determine the optimal orders of FrFT for each frame. The performance of the proposed feature is compared with traditional MFCCs on recognizing speech of isola...

Multistatic radars utilize multiple transmitter and receiver sites to provide several different monostatic and bistatic channels of observation. Multistatic passive and active radar systems can offer many advantages in terms of coverage and accuracy in the estimation of target signal parameters. Unfortunately, their performances are heavily sensitive to the position of receivers and transmitter...
