In this paper, we consider partial, feature-oriented digital twins of several virtual museums and formulate an approach to assessing them from the viewpoint of their reliability. Although the formulation specifically concerns the chosen application, it can be extended to any kind of feature-oriented digital twin. The features of a virtual museum that define its scope and focus fit into three broad categories: content, communication and collaboration. Moreover, any virtual museum needs to be risk-informed, that is, seek to support the communication and perception of different types of risks from a variety of threat categories. At the same time, appropriate algorithms should identify and analyze different types of risks for museums’ buildings, visitors, exhibitions, and pieces of art with the help of sensor data, operating rules and standards, in this way supporting stakeholders’ decision making. Using comprehensible quality criteria and their metrics, formal assessment can be carried out with the help of formulated requirements, ground truth data and related standards from the involved professional associations. Additionally, empirical assessment based on user surveys can be conducted during the museum’s lifetime. Aside from various realizations or interactive learning systems, the use cases we base our analysis on are a joint project with the Museo de Arte Contemporâneo (MAC, Santiago de Chile);a digital representation of largely destroyed works by German-Jewish sculptor Leopold Fleischhacker, a joint project initiated by the Salomon Ludwig Steinheim-Institute in Essen, presented onsite at the Düsseldorf Memorial to the Victims of Persecution;and the virtual Khachkar Museum dedicated to endangered Armenian cross stones in cooperation with the American University of Armenia. © 2022 ISRERM Organizers.

IQ is one of the indicators that has always been of interest to psychiatrists, doctors and cognitive science researchers. Since this index plays a key role in people's lives and also in the occurrence of brain abnormalities, many studies have been conducted on it. In this paper, we used the resting state magnetic resonance imaging data available in the HCP database to classify people into three groups with low, medium, and high IQ and applied machine learning methods on the matrix of causal connections between related network regions. We applied brain highlights. We calculated the matrix of causal relationships in this network by the spDCM algorithm and then obtained the differences of the three groups using the ANOVA statistical test and 6 edges out of 169 edges with p-value © 2024 IEEE.

Accurate estimation of the state of health (SoH) of lithium-ion battery (LIB) application systems is a critical concern in the domain of electric vehicles (EVs). Precise SoH holds significance due to its direct impact on the performance, longevity, and safety of LIBs. This paper proposes an efficient deep learning (DL) method for SoH estimation. The proposed DL model incorporates a residual neural network (ResNet) with long short-term memory (LSTM), extracting spatial-temporal features from LIB data. The ResNet-LSTM approach ensures high accuracy in SoH prediction. Extensive experimental results derived from real-world LIBs are presented, demonstrating the model's superiority and competitiveness in score measures when compared to existing SoH estimation models. The key contributions of this paper include (1) the simulation of a highly effective model explicitly tailored for SoH estimation in LIBs for EVs;(2) empirical verification of the effectiveness and superiority of the proposed model on the widely used NASA battery dataset. Simulation results are carried out to demonstrate the generalization and feasibility of the ResNet-LSTM model in SOH estimation with an overall root-mean-squared error of 0.69%. © 2024 IEEE.

Skin cancer is a highly prevalent form of cancer worldwide. The clinical assessment of skin lesions is crucial for evaluating the disease's characteristics. However, this assessment is often hindered by the variability in interpretations and lengthy timelines, resulting in delayed diagnoses. An advanced computer-aided diagnosis (CAD) system is needed to improve patient survival rates. This paper presents a Multi-class Skin Cancer Classification system using an enhanced VGG-16 model to improve the diagnosis of skin cancer. Our approach focuses on classifying multiple skin lesions types, specifically Melanocytic Nevus (NV), Basal Cell Carcinoma (BCC), Melanoma (MEL), and Vascular Lesions (VASC). The system was trained and evaluated on the Human Against Machine with 10,000 training images (HAM10000) dataset. We have conducted a comparative study between our method and several previously introduced techniques on the International Skin Image Collaboration (ISIC) dataset, and the results show that the proposed model outperforms previously proposed techniques. © 2024 IEEE.

Virtual memory systems rely on the page table, a crucial component that maps virtual addresses to physical addresses (i.e., address translation). While the Radix Page Table (RPT) has traditionally been used for this task, its limitations have become more apparent with the rise of memory-intensive applications. Recently, Hashed Page Tables (HPTs) have been explored as an alternative page table structure to offer faster address translation. However, the HPT introduces its own set of challenges particularly in resizing the page table and allocating contiguous physical memory space for storing the table. To tackle the fundamental problem of the existing HPT designs, this paper introduces Distributed Page Table (DPT), a novel approach that utilizes the physical memory as a huge hashed page table. DPT distributes Page Table Entries (PTEs) across the entire physical memory space, significantly reducing the hash collisions while avoiding the table resizing overheads. When distributing the PTEs across the physical memory, they can be mapped to memory locations already allocated to data pages. This new type of collision, referred to as address collision, may reduce the effectiveness of the DPT. This paper showcases that the DPT can effectively resolve the address collision with three simple yet efficient techniques: Strided Open Addressing (SOA), Collision-Aware Virtual Address Allocation (CVA) and Collided Page Displacement (CPD). Our experimental results demonstrate that DPT achieves average performance improvements of 12.6%, 11.6%, and 8.7% compared to traditional RPT, the latest large-coverage TLB design, and state-of-the-art HPTs, respectively. © 2024 IEEE.

Spaceborne platforms like the NASA SMAP and the ESA SMOS offer global-scale coarse-resolution observations that can be used to estimate surface soil moisture. However, they acquire observations at a moderate revisit frequency, reducing the impact on applications that require higher temporal resolutions. Global navigation satellite system reflectometry (GNSS-R) is a prime example of a signal-of-opportunity (SoOP) which has been shown to be highly sensitive to variations in soil moisture. In this work, we consider measurements from the NASA Cyclone GNSS (CYGNSS) mission which consists of eight low-orbit observatories, that are equipped with two nadir-looking antennas to receive reflected GPS signals. To extract soil moisture content, the traditional approach involves inverting parameterized forward models which account for aspects like dielectric properties of the soil, topography, and incidence angle information among others. Despite their potential, these models typically involve simplified assumptions and demonstrate increased sensitivity to the values of different parameters. To address this challenge, a new line of research tries to address this challenge by utilizing machine learning models and treating the problem as that of supervised regression. © 2024 IEEE.
