Signal Output

EMAT using a magnetostrictive effect was employed to detect flaws in the sample with scaled surface. Chromium molybdenum steel samples were annealed from 600 °C to 900°C for two hours to eight hours and subjected to EMAT to survey its signal properties. The signal output was found to have too much noise to identify internal flaws and to reconstruct flaw images in a computer. This study proposes spectrum analysis methods and statistical methods based on the noise probability to decrease this noise.

The paper studied 130 colorative idioms with colorative red (RI) in three languages from electronic sources, with a focus on current vocabulary from the 20th and 21st centuries. RIs numerous meanings were investigated, then merged into trilingual associative chains, and finally into seven microsystems, using statistical, comparative, linguistic, and linguistic-cultural analysis methods within the framework of the linguocultural approach to RI: Blood color-activity-disease-medical care-shame-irritation - anger - aggression - crime - murder; Fire - attractiveness; Danger - prohibition – border- red-green; Revolution - anarchism-communism; Prestige- holiday; Sex; Red object's color. We also found trilingual extra-associative RIs, which have meanings not found in the associative chains. The study examined RI quantitatively, identifying trilingual equivalent and lacunar idioms, linked between RI and red in nature, noting the formation of new RI meanings and connotation changes in three languages through time. Polysemy, antinomy with different hues (green, black, white, and blue), international neologisms (computer technology, the stock market, the coronavirus pandemic), and the relevance of RI in modern languages and linguistic culture were the topics covered in this research.

Three Phase Inverter

Aiming at the spectrum analysis, the classification of PWM strategies based on digital implementation for the three-phase inverter is given. Then the paper summaries the three spectrum analysis methods: theoretical expression, computer simulation and experiment. The structure and procedure of each method are discussed. Each method has advantages and disadvantages. The experiment and computer simulation can be used to analyze any PWM strategy. The theoretical expression is always used to analyze the deterministic strategies.
