Spinning structure is one of important types of classical gyroscopic continua, and many interesting phenomena of the gyroscopic continua have been found due to the gyroscopic effect. In this paper, the vibration characteristic analysis of the spinning cantilever beam is studied. The two linear partial differential equations governing two transverse vibrations are derived by the extended Hamilton principle. The ordinary differential dynamic equations are obtained by using the modal expansion of Galerkin method. The natural frequencies, complex modes, and stability of the spinning cantilever beam are investigated by solving the standard eigenvalue problems of the linearized system directly. Some novel interesting phenomena have been obtained numerically and important conclusions have been drawn for this special spinning system.

In the rapid development of science and technology today, the intelligence of the visual system has been highly valued. The recognition and detection of pedestrian attitudes in a complex environment have become the application trend of intelligent video. The widely used of camera machine does not have such a function. Therefore, this article deeply discusses the relevant algorithms of pedestrian gesture detection and recognition based on machine learning. The traditional HOG feature detection can only achieve the relevant detection of the upright walking crowd target. While when the pedestrian makes different gestures, its detection effect is directly affected and challenging to be recognized. So, this article uses the checking methods of the deformable part model (DPM) to check the target pedestrian gesture and elaborate pedestrian's attitude estimation algorithm for the deformable parts principle. Finally, it combines the algorithm with HOG+SVM principles to simulate with the MATLAB and gets the experimental results to show that this approach can make a pedestrian posture test implemented to achieve high precision accuracy.

With the development of energy Internet technology, the types and number of terminals in substations have shown an explosive growth trend, which puts forward higher requirements for image compression and image processing capabilities. Therefore, this paper proposes a method to improve the quality of power image transmission. Firstly, the eigenvalues and special vectors of the image are obtained, and then the wavelet transform method is used to encode the image, and finally the compressed image after decoding is obtained. Based on a typical field case, the comparison of experimental data under various algorithms is carried out. The results show that the improved method proposed in this paper has better image compression quality and higher peak signal-to-noise ratio, and improves the transmission quality of substation field monitoring images. It provides new technical ideas for the development of big data processing of electric power images.

In this paper, the adaptive fuzzy neural network (AFNN) based on the surface electromyography (sEMG) for estimating the elbow joint angle is established and investigated from the perspective of rapidity and accuracy. In addition, back propagation neural network (BPNN) and artificial neural network of radial basis function (RBFNN), as the classical method for data forecasting, have been applied to estimate the elbow joint angle for comparing with AFNN. Ultimately, the experimental simulation and result analysis demonstrate that the rapidity and accuracy of AFNN is superior to BPNN and RBFNN.

In the era of artificial intelligence, advanced information technology has been applied to corporate financial work, changing the functions, work objects, and structure of traditional financial accounting. At the same time, advanced technology makes the financial accounting work unable to meet the needs of the development of the times, which promotes the transition from financial accounting to management accounting. Based on the analysis of the impact of artificial intelligence on financial accounting, this article will combine the characteristics of the two to analyze the problems of financial accounting in the artificial intelligence era and the advantages of management accounting. The author offers several views on how to achieve effective transformation.

In order to consider the incomplete maintenance problem into the transformer state maintenance strategy, this paper proposes a transformer state maintenance strategy based on the proportional strength model. First of all, this paper establishes a transformer proportional strength model, and gives a detailed calculation model of incomplete maintenance parameters in the proportional strength model. And this article has determined its reasonable value range and clarified the overhaul effect of incomplete overhaul activities. Secondly, this paper uses the least cost method to determine the condition maintenance threshold curve of the proportional strength model, and adds the lower limit of the threshold as the restrictive index of the condition maintenance strategy. Then, this paper uses actual transformer fault statistics and condition monitoring data to carry out a calculation example analysis. Finally, the effectiveness of the proportional strength model in the case of incomplete overhaul is verified through the analysis of a calculation example, which provides a reliable theoretical basis for the decision-making of the transformer's condition overhaul.

In view of the problem that contemporary residential students can't enjoy bathing anytime and anywhere, we use raspberry pie and sensor to simulate the bathroom environment to obtain real-time data of bathroom, and calculate the specific time of bathing through algorithm. In addition, we use HTML5, CSS, JavaScript to realize the remote reservation function, so that users can remotely turn on or off the water heater switch. The power consumption and usage times of the water heater will be recorded in the database, and an electronic report will be generated for one month.
