Optimization of BP Neural Network Model Based on Improved Sine-Cosine Algorithm

Shijin Tan,Yimeng Wang
Reservoir rock porosity is usually determined by core analysis, but the cost of this method is huge, in order to establish a more accurate and stable reservoir porosity prediction model. Using the logging data of the existing work area, we optimize the neural network using the improved sine-cosine algorithm, add nonlinear weights to the position change of the sine-cosine algorithm (SCA) to correct the individual position and improve the convergence accuracy of the algorithm, incorporate the Levy...

Quantum Measurement, the Simplest Interpretation

Carlos López
Many di?erent interpretations of the Quantum Theory have appeared over the one hundred years since its ?rst formulation. The paper presents a detailed physical analysis of the process of quantum measurement, which is crucial in the development of a sound interpretation of the theory. The process of quantum measurement can be decomposed into three elementary steps, and the projection of state (or collapse of the wave function) is applied at the last step, the reading of the result of measurement ...

Biomass, Grain and Nitrogen Harvest Index of Rainfed Corn with Organic and Inorganic Fertilization in a Rhodic Luvisol of Yucatan, Mexico

Jorge Humberto Ramírez Silva,José de la Cruz Tun Dzul,Alejandro Cano González,Alejandro Escalente Ávila
Corn is the staple crop in Yucatan, Mexico, mainly grown on stony soils like the Leptosols, with low productive potential, but it is also cultivated in arable areas of rhodic Luvisols with better potential. However, due to an imminent, continuous demand for technology, basic nutrimental studies are needed. Fertilization, associated with plant nutrition, is the most demanding technology since it is the most expensive input. Fertilization programs should pay attention to indicators relate...

Effects of Blackboard Teaching and PPT Teaching in High School Mathematics Classroom Based on Cognitive Load Theory

Shenxin Ou,Xuekun Ou
The knowledge system of high school mathematics is extensive, logically rigorous, highly abstract, and challenging. Reasoning-based teaching is the primary method, with blackboard teaching and PPT teaching being common instructional tools. This study, based on cognitive load theory, explores the effectiveness of these two teaching methods in high school mathematics classrooms. First, it explains the concept of cognitive load, including intrinsic, extraneous, and germane cognitive load. Then, it ...

A Comparative Study of English and Chinese Discourse Aesthetic Choice and Its Translation
—Taking the Introduction of Chinese and American National Libraries as an Example

Mei Dong,Yuan Gao
The combination of aesthetic linguistics theory and translation practice is an effective way to cultivate the aesthetic sense of translation. The integration of aesthetic linguistics theory research and translation practice makes translation practice a process of language activity with more practical and aesthetic value, which can enhance people’s consciousness, creativity and appreciation of language beauty and linguistic beauty. With the guidance of aesthetic linguistics and the use of compara...
