“…Unlike vague and elusive verbal expressions, visual expressions are straightforward and simple, yet rich and clear. Therefore, the creators of American postmodern novels have a variety of visual perceptions when they study, which is very beneficial to their self-cognition ability [ 35 ]. The direct experience of images is much more effective than repeated repetition of words.…”

Objective. Therapeutic intervention can improve the overall level of mental health of American postmodern fiction writers by improving their social communication skills and overall well-being. This paper discusses the application of art therapy in the mental health education of American postmodern novel creators and proves that expressive art therapy intervention is effective in improving the mental health level of American postmodern novel creators. Method. This article attempts to help American postmodernist novel creators understand their own mental health status by means of individualized assessment and therapeutic intervention and to analyze and discover their own potential mental health problems. The writers of postmodernist novels in the USA were measured and screened by means of scales and questionnaires, and the members who met the experimental intervention were divided into experimental group and control group, and the experimental group received a 30-day reception music therapy intervention. After the intervention, the data will be counted, and the quantitative and qualitative aspects will be analyzed to comprehensively evaluate the effect of the intervention. Results/Discussion. Receptive music therapy intervention has a significant effect in relieving the anxiety of American postmodernist novel creators and plays a positive role in helping American postmodernist novel creators better adapt to study life and build good emotional psychology and interpersonal relationships. Psychological counseling relies more on external forces to correct cognition and adjust psychology, while music therapy intervention, as a nonsemantic art, can arouse inner functions and mobilize the self-healing potential of American postmodern novel creators. Practice has proven that when the language intervention of traditional psychotherapy encounters resistance and silence, music as a special language plays a vital role. The nonlinguistic nature of music, through a mode of reproduction of sounds in nature, makes the beautiful and soothing melody stimulate a pleasant and peaceful psychological experience through human hearing.

“…In recent years, with economic development and social progress, psychological crisis has become a very serious social problem; the university campus is also inevitably affected [ 2 ]. College students are facing increasing pressure from competition, the economy, study, employment, and emotions, and they are more likely to encounter or produce various psychological problems [ 3 ]. Today's world is in an era of fierce competition.…”

With the economic development and social progress, psychological crisis has become a very serious social problem, and the university campus is also inevitably affected. College students’ ability to resist pressure is poor, their psychology fluctuates greatly and changes constantly, and they are easily influenced by the outside world. Mental health assessment is a scientific means to quantitatively analyze and infer the characteristics of psychological changes in people’s behaviors by measuring and observing people’s representative behaviors in a strictly controlled environment. Analytic hierarchy process (AHP) is a method to determine the relative importance weight and relative order of advantages and disadvantages of various factors in the system, while fuzzy comprehensive evaluation is an effective method to evaluate fuzzy things comprehensively. This paper introduces the principle of the fuzzy comprehensive evaluation method, analyzes the feasibility and applicability of the fuzzy comprehensive evaluation method in social work evaluation of college students’ mental health schools, and draws relevant research conclusions and suggestions.

“…Second-order cyclostationarity, or wide-sense cyclostationarity, appears to be the intrinsic property exhibited by processes generating signals belonging to different classes. Thus, there are plenty of examples where it was reasonably taken into account in many research fields and engineering applications, including communication signals with various modulation schemes [ 6 ], radio signals used in passive radars [ 7 , 8 ], electromagnetic measurements with near-field probes [ 9 , 10 ], spectral sensing in cognitive radio [ 11 ], mechanical vibration of rotary machines [ 12 , 13 ], radio astronomy [ 14 , 15 ], power analysis of electric circuits [ 16 ], generalized detection [ 17 , 18 ] under conditions of the least certainty, electromagnetic compatibility [ 19 , 20 ], detection of vital signs in radar response [ 21 , 22 ], drone navigation signals [ 23 ] and others.…”

This article addresses the problem of estimating the spectral correlation function (SCF), which provides quantitative characterization in the frequency domain of wide-sense cyclostationary properties of random processes which are considered to be the theoretical models of observed time series or discrete-time signals. The theoretical framework behind the SCF estimation is briefly reviewed so that an important difference between the width of the resolution cell in bifrequency plane and the step between the centers of neighboring cells is highlighted. The outline of the proposed double-number fast Fourier transform algorithm (2N-FFT) is described in the paper as a sequence of steps directly leading to a digital signal processing technique. The 2N-FFT algorithm is derived from the time-smoothing approach to cyclic periodogram estimation where the spectral interpolation based on doubling the FFT base is employed. This guarantees that no cyclic frequency is left out of the coverage grid so that at least one resolution element intersects it. A numerical simulation involving two processes, a harmonic amplitude modulated by stationary noise and a binary-pulse amplitude-modulated train, demonstrated that their cyclic frequencies are estimated with a high accuracy, reaching the size of step between resolution cells. In addition, the SCF components estimated by the proposed algorithm are shown to be similar to the curves provided by the theoretical models of the observed processes. The comparison between the proposed algorithm and the well-known FFT accumulation method in terms of computational complexity and required memory size reveals the cases where the 2N-FFT algorithm offers a reasonable trade-off.
