FAULT DIAGNOSIS OF ROLLING BEARINGS BASED ON SDP AND IMPROVED SAM⁃MobileNetv2 by ZHANG TianYuan, SUN HuEr, ZHU JiYang, ZHAO Yang

“…Traditional fault diagnosis methods for rolling bearings are difficult to accurately and efficiently achieve fault classification.A method of rolling bearing fault classification based on symmetrized dot pattern(SDP)and improved SAM⁃MobileNetv2 was proposed.Firstly,the bearing vibration signal was transformed into two⁃dimensional images with rich characteristic information by SDP algorithm.Secondly,the two⁃dimensional images were fed into the SAM⁃MobileNetv2 network model,which extracted and classified fault feature information.Improved SAM⁃MobileNetv2 networks used the adaptive activation function ACON to replace the ReLU6 activation function in SAM⁃MobileNetv2 to improve model classification performance.Finally,this model was compared with various models.The experimental results show that this model can accurately and efficiently realize the classification of rolling bearing faults,using Case Western Reserve University bearing fault data with an accuracy rate of 99.5%,using the University of Ottawa bearing failure data with an accuracy rate of 97.2%.…”

Cuerpos sometidos, sujetos educados. Apuntes para una interpretación de las luchas discursivas por la construcción de la educación sexual en Colombia by Alexánder Hincapié, Sebastián Quintero

“…El presente artículo de investigación utiliza como pre-texto el caso de dos estudiantes expulsadas de un conocido colegio de Manizales por su orientación sexual, para presentar distintos trabajos que abordan el problema de la educación sexual en Colombia, desde los años 70 hasta finales de los años 90. Si el gesto del Ministerio de Educación Nacional en el año 1994, delarando obligatorio realizar proyectos pedagógicos de educación sexual, para algunos resultaba inédito, no aparece tan singular -y esta es nuestra tesis- que los criterios para impartir esa educación sexual en la vida misma de las escuelas y colegios, ahora reordenados bajo una reglamentación y al cuidado de los saberes expertos en sexualidad, mantuviesen sustancialmente la homofobia como un producto de la educación.…”

Book Review of Economic Theories of Development: An Analysis of Competing Paradigms by Seyed hossein Mirjalili

“…Another critique to the text is incommensurability of paradigms that constitute the book's approach.Economic methodologists, who viewed economics from the perspective of Cohen’s scientific revolution, have recognized Keynesian economics as a true paradigm shift in economics, and development economists recognized the shift from modernization to dependency theory as a true paradigm shift in development. Finally, institutionalist approach to economic development was neglected and has not been discussed in the text.…”
