We provide a concise review of the exponentially convergent multiscale finite element method(ExpmsFEm)for efficient model reduction of PDEs in heterogeneous media without scale separation and in high-frequency wave *** ExpmsFEm is built on the non-overlapped domain decomposition in the classical msFEm while enriching the approximation space systematically to achieve a nearly exponential convergence rate regarding the number of basis *** most generalizations of the msFEm in the literature,the ExpmsFEm does not rely on any partition of unity *** general,it is necessary to use function representations dependent on the right-hand side to break the algebraic Kolmogorov n-width barrier to achieve exponential ***,there are online and offline parts in the function representation provided by the *** online part depends on the right-hand side locally and can be computed in parallel *** offline part contains basis functions that are used in the Galerkin method to assemble the stiffness matrix;they are all independent of the right-hand side,so the stiffness matrix can be used repeatedly in multi-query scenarios.

One objective of developing machine learning(mL)-based material models is to integrate them with well-established numerical methods to solve boundary value problems(BVPs).In the family of mL models,recurrent neural networks(RNNs)have been extensively applied to capture history-dependent constitutive responses of granular materials,but these multiple-step-based neural networks are neither sufficiently efficient nor aligned with the standard finite element method(FEm).Single-step-based neural networks like the multi-layer perceptron(mLP)are an alternative to bypass the above issues but have to introduce some internal variables to encode complex loading *** this work,one novel Frobenius norm-based internal variable,together with the Fourier layer and residual architectureenhanced mLP model,is crafted to replicate the history-dependent constitutive features of representative volume element(RVE)for granular *** obtained mL models are then seamlessly embedded into the FEm to solve the BVP of a biaxial compression case and a rigid strip footing *** obtained solutions are comparable to results from the FEm-DEm multiscale modelling but achieve significantly improved *** results demonstrate the applicability of the proposed internal variable in enabling mLP to capture highly nonlinear constitutive responses of granular materials.

Logical Image Acquisition and Analysis of Android Smartphones

引用

Journal of Computer and Communications 2024年第4期12卷 139-152页

作者： Nursel yalçın Tayfun yıldırım Department of Computer and Instructional Technologies Education Faculty of Education Gazi University Ankara T&#252rkiye Department of Computer Forensics Institute of Informatics Gazi University Ankara T&#252rkiye

Android smartphones largely dominate the smartphone market. For this reason, it is very important to examine these smartphones in terms of digital forensics since they are often used as evidence in trials. It is possible to acquire a physical or logical image of these devices. Acquiring physical and logical images has advantages and disadvantages compared to each other. Creating the logical image is done at the file system level. Analysis can be made on this logical image. Both logical image acquisition and analysis of the image can be done by software tools. In this study, the differences between logical image and physical image acquisition in Android smartphones, their advantages and disadvantages compared to each other, the difficulties that may be encountered in obtaining physical images, which type of image contributes to obtaining more useful and effective data, which one should be preferred for different conditions, and the benefits of having root authority are discussed. The practice of getting the logical image of the Android smartphones and making an analysis on the image is also included. Although root privileges are not required for logical image acquisition, it has been observed that very limited data will be obtained with the logical image created without root privileges. Nevertheless, logical image acquisition has advantages too against physical image acquisition.
