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 ...
A unified formulation of geometry-aware discrete dynamic movement primitives
(Elsevier, 2024)
Learning from demonstration (LfD) is considered as an efficient way to transfer skills from humans to robots. Traditionally, LfD has been used to transfer Cartesian and joint positions and forces from human demonstrations. ...
Engineered design of cutting tool material, geometry, and coating for optimal performance and customized applications: A review
(Elsevier, 2024)
Cutting tool materials are the backbone of machining and play a vital role in the manufacturing industry. Innovation in cutting tools is important for customized and demanding applications. This state-of-the-art review is ...
Determinación y creatividad en tiempos de pandemia
(Editorial Universidad de Granada, 2024-06-11)
Durante el confinamiento decretado en el período de alarma sanitaria provocada por la COVID-19, en España se suspendieron todas las actividades educativas de carácter presencial forzando la utilización de vías de trabajo ...
Digital Robot Judge: Building a Task-centric Performance Database of Real-World Manipulation With Electronic Task Boards
(IEEE, 2024)
Robotics aims to develop manipulation skills approaching human performance. However, skill complexity is often over- or underestimated based on individual experience, and the real-world performance gap is difficult or ...
Tool Geometry Optimisation for LCO2 Assisted Milling of Ti6Al4V
(Elsevier, 2024)
Titanium alloy Ti6Al4V is of great importance to the aeronautical and medical sectors due to its mechanical properties such as a high strength-to-weight ratio and corrosion resistance. On the downside, machining Ti6Al4V ...
