ABSTRACT Switched reluctance motors (SRMs) have gained popularity in various industrial applications due to their advantages, including structural simplicity, high reliability, low cost, and operational stability over a wide speed range without relying on rare‐earth permanent magnet materials. However, these exhibit drawbacks such as weak torque density, efficiency, significant ripple, particularly high‐speed operation. An efficient converter‐based control approach is proposed manage variations SRM motors, addressing issues. A multilevel converter (MC) introduced fundamental component. The novel (NMC) accommodates SRMs with varying numbers of phases exhibits quick demagnetization excitation behaviors, enabling independent operation each phase even during conduction overlaps. Subsequently, an effective controller developed for the motor, combining proportional integral derivative (PID) enhanced fire hawks optimization (EFHO). EFHO optimizes PID gain values enhance performance. minimizes ripple facilitates management. technique fusion (FHO) sine cosine algorithm (SCA). This amalgamation improves updating process FHO by incorporating SCA. methodology implemented MATLAB evaluated through metrics, motor current, voltage, speed, torque, under electric vehicle (EV) load conditions. Performance comparisons are conducted traditional algorithms whale (WOA) ant colony (ACO). results validate effectiveness achieving improved

The deep integration of computer field and coal mining is the only way to mine intellectualization. A variety artificial intelligence tools have been applied in open-pit shallow mines. However, with geometric increase demand, contradiction between supply demand becoming more serious, exploitation resources from layer (> 600 m) has become an inevitable trend. Well then, as a new engineering scene, harsh conditions "three high one disturbance" seriously threaten safety personnel. superposition complex environment makes number input factors sharply, which leads application roadway engineering. guidance not mature, construction various databases missing, there are still some problems universality applicability. To this end, paper starts introduction operating characteristics tools, conducts comprehensive study relevant high-level articles published top journals. It systematically sorts out research progress that successfully solved five directions rock mechanics strength, surrounding stability, rock-burst, roof fall risks micro-seismic events. While objectively evaluating performance different it also expounds its own views on key results. Literature review shows whether development tool or comparative model, ANN than 98%, performs extremely well direction stability risk, accuracy rate 90%. As most mature AI application, mechanical strength experienced process "SVM → DL XGBoost RF". dataset small samples (< 100) big 1000), R2 tree-based models can be stabilized at 95%. rock-burst prediction mainly focuses monitoring data. Whether sample large-scale data BN remains above 85%. evaluation events recent years. image processing CNN important. signal recognition classification accounts for 90%, potential source location needs further explored. In general, nature itself first choice almost all influencing factors. At same time, update iteration methods (micro-seismic, ground sound, separation, deformation, etc.) expands database, making possible obtain due threat life cost equipment, very difficult before. parameter selection method combining lithology conditions, geological will gradually research. Finally, follow-up work collation on-the-spot investigation, existing mines, explores engineering, puts forward focus challenging future, gives opinions.

Quantitative structure-activity relationship (QSAR) models are powerful in silico tools for predicting the mutagenicity of unstable compounds, impurities and metabolites that difficult to examine using Ames test. Ideally, Ames/QSAR regulatory use should demonstrate high sensitivity, low false-negative rate wide coverage chemical space. To promote superior model development, Division Genetics Mutagenesis, National Institute Health Sciences, Japan (DGM/NIHS), conducted Second International Challenge Project (2020-2022) as a successor First (2014-2017), with 21 teams from 11 countries participating. The DGM/NIHS provided curated training dataset approximately 12,000 chemicals trial 1,600 chemicals, each participating team predicted various models. then test results assist improvement. Although overall performance on was not First, eight both projects achieved higher sensitivity than only Project. Thus, these evaluations have facilitated development QSAR
