this study focuses on tracing the clearly defined elements of magic realism in toni morrison’s song of solomon as an illustrious african american example of the mode. magic realism is a fictional technique that combines fantasy with raw physical reality in a search for truth beyond that available from the surface of everyday life. toni morrison, as a distinguished african-american practitioner ...
Technology for classifying low probability of intercept (LPI) radar signals with speed and accuracy is critical cognitive communication research. We used time-frequency analysis (TFA) deep learning to classify 12 typical LPI signals. Traditional methods use the Choi-Williams distribution (CWD), which requires more than 500 times longer TFA generation time spectrogram method. In this paper, we s...
The dominant feature in the acoustic spectrum of a propeller-driven aircraft is the spectral line corresponding to the propeller blade rate that is equal to the product of the propeller shaft rotation rate and the number of blades on the propeller. The frequency of this line, when measured by a stationary observer on the ground, changes with time due to the acoustical Doppler effect. In this pa...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
abstract: literature is said beautiful words of poetry or prose that excites reader’s or listener’s feel. certainly, to be effective, such a text should have certain characteristics. the four elements of the literature: thought, imagination, emotion and style make a text to be literary and effective. emotion and imagination are specific elements of literary texts, while thought and style a...
A comparison of linear and quadratic transform implementation on field programmable gate array (FPGA) is presented. Popular namely Stockwell Transform Smoothed Pseudo Wigner Ville Distribution (SPWVD) from Quadratic transforms considered for the FPGA. Both are coded in Verilog hardware description language (Verilog HDL). Complex calculations transformation performed by using CORDIC algorithm. F...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
