Abstract:
Abstract Understanding the failure of brittle heterogeneous materials is essential in many applications. Heterogeneities in material properties are frequently modeled through random fields, which typically induces the need to solve finite element problems for a large number of realizations. In this context, we make use of reduced order modeling to solve these problems at an affordable computational cost. This paper proposes a reduced order modeling framework to predict crack propagation in brittle materials with random heterogeneities. The framework is based on a combination of the Proper Gene

Abstract:
Spoofing attacks using imitations of fingerprints of legal users constitute a serious threat. In this study, a terahertz time domain spectroscopy (TDS) setup in a reflection configuration was used for the non-intrusive detection of fingerprint spoofing. Herein, the skin structure of the finger pad is described with a focus on the outermost stratum corneum. We identified and characterized five representative spoofing materials and prepared thin and thick finger imitations. The complex refractive index of the materials was determined in TDS in the transmission configuration. For dataset collecti

Abstract:
AbstractReduced order modeling (ROM) techniques are numerical methods that approximate the solution of parametric partial differential equation (PED) by properly combining the high-fidelity solutions of the problem obtained for several configurations, i.e. for several properly chosen values of the physical/geometrical parameters characterizing the problem. By starting from a database of high-fidelity solutions related to a certain values of the parameters, we apply the proper orthogonal decomposition with interpolation (PODI) and then reconstruct the variables of interest for new values of the

Abstract:
Despite significant development in facial recognition (FR), current FR systems are exposed to spoofing attacks like printed photo attacks, 3D mask attacks, video replay attacks, and many more. Several anti-spoofing approaches have been proposed to assess whether the person in front of the camera is real or fake. Developing effective protection mechanisms against these threats is a challenging task. This paper gives a brief overview of various presentation attack detection (PAD) techniques, which are categorized into intrusive and non-intrusive approaches. Each technique is examined in terms of

Abstract Introduction Sacral radiculopathy is defined as inflammatory irritation in the cauda equina of S2-S3 nerve roots formed by the convergence of the pelvic, pudendal, and sciatic nerves. Sacral radiculopathy can cause unwanted or intrusive, persistent or recurrent, distressing clinical symptoms involving the sensory fields of these nerves in the genito-pelvic region termed genito-pelvic dysesthesia (GPD).

Woven reinforced composites are often hindered by challenges in accurately predicting their mechanical behavior. This obstacle primarily stems from the heterogeneous nature of these materials. Consequently, employing multi-scale approaches becomes imperative to ascertain their overall responses under complex loading conditions, incorporating detailed descriptions of microstructure and the constitutive laws governing their components. However, effectively incorporating these methodologies into real-scale applications, particularly within FE² analyses, remains challenging due to the significant

L'un des principaux avantages de la méthode «Proper Generalized Decomposition», par rapport à d'autres méthodes de réduction de modèles, réside dans son adéquation pour calculer des représentations séparées dans l’espace pour des domaines dégénérés de type cartésien, tels que des plaques ou des coques. L'objectif principal de cette thèse est de généraliser les représentations séparées dans l’espace aux domaines non cartésiens, en introduisant la notion de représentations séparées.

Despite an elevated computational cost, the optimization procedure was capable of generating a Pareto front of turbine geometries which improved the mean isentropic turbine efficiency μ(ηs) over the baseline profile, while li

Abstract Among the many applications of Coiled Tubing (CT) services, milling plugs and wellbore sand cleanout are two of the major applications. The transport of solids to the surface, as well as monitoring the return rates, are two sources of information which can have a significant impact on the execution of these jobs. Traditionally the flowback crew communicates this information to the CT control cab upon request. However, by utilizing an acoustic monitor and ultrasonic flowmeter, it can reduce the dependence on flowback operators and provide real-time solid measurement and return flow rat
