Error estimation in current noisy quantum computers
(Springer Nature, 2024)
One of the main important features of the noisy intermediate-scale quantum (NISQ) era is the correct evaluation and consideration of errors. In this paper, we analyse the main sources of errors in current (IBM) quantum ...
Bending rigidity, sound propagation and ripples in flat graphene
(Springer Nature, 2024)
Many of the applications of graphene rely on its uneven stiffness and high thermal conductivity, but the mechanical properties of graphene—and, in general, of all two-dimensional materials—are still not fully understood. ...
Effect of the loading-rate and stress state on the constitutive modelling and fracture of 2205 Duplex stainless steel
(Elsevier, 2024)
Shear cutting is a high-speed forming process where material separation is involved. The nature of the process leads to high strain rates and temperatures on the sheared zone of the material subjected to the operation. In ...
Uncertainty Distribution Assessment of Jiles-Atherton Parameter Estimation for Inrush Current Studies
(IEEE, 2024)
Transformers are one of the key assets in AC distribution grids and renewable power integration. During transformer energization inrush currents appear, which lead to transformer degradation and can cause grid instability ...
Combining experimental and FEM approaches to determine the influence of workpiece temperature on fundamental variables in the machining process
(Materials Research Forum LLC, 2024)
In machining it is common practice to use lubricants to enhance machinability, resulting in improved part quality and reduced tool wear. However, emerging efforts are centered on mitigating the environmental impact of ...
Non-destructive experimental technique to determine ball contact load in rolling machine elements
(Elsevier, 2024)
Rolling machine elements, such as ball bearings, ball screws, or guiding systems are commonly used in diverse industrial applications. These components typically assume uniform load distribution among the balls or rely on ...
Identification of the Constitutive and Friction Models Parameters via a Multi-Objective Surrogate-Assisted Algorithm for the Modeling of Machining - Application to Arbitrary Lagrangian Eulerian Orthogonal Cutting of Ti6Al4V
(ASME, 2024)
The evolution of high-performance computing facilitates the simulation of manufacturing processes. The prediction accuracy of a numerical model of the cutting process is closely associated with the selection of constitutive ...
A general kinematic model for lubricated ball bearings based on the minimum energy hypothesis
(Elsevier, 2024)
Accurately predicting the performance of lubricated rolling elements is critical for certain key bearing applications. A widely employed simulation technique is quasi-static models, which although computationally efficient ...
Introducing Students to Web Engineering Topics by Teaching Web Augmentation
(River Publishers, 2024)
Web augmentation has gained prominence as a promising approach to elevate the user experience by tailoring web content to meet diverse user needs and preferences. It offers the potential to enhance accessibility and ...
The impact of airborne emissions from coolants and lubricants on machining costs
(Elsevier, 2024)
A novel aerosol evaluation cell was employed to measure particle number and mass concentration, with a size distribution from nano to micro scale. Different cooling/lubrication and airflow extraction scenarios were tested ...
