Vibration Fatigue Life Reliability Cable Trough Assessment by Using Weibull Distribution
(2023-03-30)In this paper, the formulation to incorporate the used vibration profile, the stress generated by the product’s application, mass, and the resonance frequency is given. After that, based on the vibration output data, the ... -
Efectos del conflicto trabajo-ocio: un análisis multigrupo entre centennials y millennials
(2023-03-16)El trabajo y el ocio son actividades distintas, pero ambas importantes para la vida. Esta investigación analizó el efecto del conflicto trabajo-ocio en el desempeño, mediado por estrés percibido y satisfacción laboral. Se ... -
Weibull stress method to determine the minimum required strength to improve the actual reliability
(2023-03-21)The method to determine the minimum strength that a product must present to improve the product’s reliability from its actual R(t) to a desired R(t2) index are given. Themethod can be performed in both the normal and ... -
Pre-twisted calculus and differential equations
(2023-07-10)In this paper we introduce the φA-differentiability for functions f:U⊂R^k→R^n, where U is an open set, A is the linear space R^n endowed with a unital associative commutative algebra product, and φ:U⊂R^k→A is a differentiable ... -
Residual 3D convolutional neural network to enhance sinograms from small-animal positron emission tomography images
(2023-05-05)Positron emission tomography (PET) has been widely used in nuclear medicine to diagnose cancer. PET images suffer from degradation because of the scanner’s physical limitations, the radiotracer’s reduced dose, and the ... -
Effective properties of centro-symmetric micropolar composites with non-uniform imperfect contact conditions
(2023-06-01)In this work, the homogenization theory is addressed within the framework of three-dimensional linear micropolar composite materials with centro-symmetric constituents and non-uniform imperfect interface conditions. The ... -
An interactive ACO enriched with an eclectic multi-criteria ordinal classifier to address many-objective optimisation problems
(2023-06-20)Despite the vast research on many-objective optimisation problems, the presence of many objective functions is still a challenge worthy of further study. A way to treat this kind of problem is to incorporate the preferences ... -
Una ingeniería con ética
(2023-07-30)El propósito del presente trabajo es discutir la ética en ingeniería con base en las filosofías Kantiana y la de los mun-dos sensibles e ideales. Esta discusión considera que la conducta ética en ingeniería es difícil de ... -
Immunotherapy in Combination with Chemotherapy for Triple-Negative Breast Cancer
(2023-05-17)Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer that lacks estrogen and progesterone receptors and does not overexpress the human epidermal growth factor receptor 2 (HER2). Previous treatment ... -
Influence of γ phase on the magnetostructural transition and magnetocaloric properties in Ni38Co12Mn41Sn9 melt-spun ribbons
(2023-06-05)In the present work, Ni38Co12Mn41Sn9 melt-spun ribbons were annealed under different conditions to make samples free of secondary γ phase precipitates or get them with various average grain sizes. A comparative study was ... -
Effect of imperfect interface on the effective properties of elastic micropolar multi-laminated nanostructures
(2023-02-09)In this paper, the problem of a heterogeneous elastic micropolar nanostructure with a periodic structure subject to imperfect contact conditions is analyzed through the two-scale asymptotic homogenization method (AHM). ... -
An Additive Chen Distribution with Applications to Lifetime Data
(2023-01-24)This paper presents a lifetime model with properties representing increasing, decreasing, and bathtub curve shapes for failure rates. The proposed model was built based on the additive methodology, for which the Chen ... -
