HIDE:Hierarchical Iterative Decoding Enhancement for Multi-view 3D Human Parameter Regression
Authors: Lin Weitao , Zhang Jiguang , Meng Weiliang , Liu Xianglong , Zhang Xiaopeng
Published: June 2024

Parametric human modeling are limited to either single-view frameworks
or simple multi-view frameworks, failing to fully leverage the
advantages of easily trainable single-view networks and the
occlusion-resistant capabilities of multi-view images. The prevalent
presence of object occlusion and self-occlusion in real-world scenarios
leads to issues of robustness and accuracy in predicting human body
parameters. Additionally, many methods overlook the spatial connectivity
of human joints in the global estimation of model pose parameters,
resulting in cumulative errors in continuous joint parameters.To address
these challenges, we propose a flexible and efficient iterative decoding
strategy. By extending from single-view images to multi-view video
inputs, we achieve local-to-global optimization. We utilize attention
mechanisms to capture the rotational dependencies between any node in
the human body and all its ancestor nodes, thereby enhancing pose
decoding capability. We employ a parameter-level iterative fusion of
multi-view image data to achieve flexible integration of global pose
information, rapidly obtaining appropriate projection features from
different viewpoints, ultimately resulting in precise parameter
estimation. Through experiments, we validate the effectiveness of the
HIDE method on the Human3.6M and 3DPW datasets, demonstrating
significantly improved visualization results compared to previous
methods.
Peridynamic-Based Modeling of Elastoplasticity and Fracture Dynamics
Authors: Wang Haoping , Wang Xiaokun , Xu Yanrui , Zang Yanlan , Yao Chao , Guo Yu , Ban Xiaojuan
Published: June 2024

This paper introduces a particle-based framework for simulating the
behavior of elastoplastic materials and the formation of fractures,
grounded in Peridynamic theory. Traditional approaches, such as the
Finite Element Method (FEM) and Smoothed Particle Hydrodynamics (SPH),
to modeling elastic materials have primarily relied on discretization
techniques and continuous constitutive model. However, accurately
capturing fracture and crack development in elastoplastic materials
poses significant challenges for these conventional models. Our approach
integrates a Peridynamic-based elastic model with a density constraint,
enhancing stability and realism. We adopt the Von Mises yield criterion
and a bond stretch criterion to simulate plastic deformation and
fracture formation, respectively. The proposed method stabilizes the
elastic model through a density-based position constraint, while
plasticity is modeled using the Von Mises yield criterion within the
bond of particle paris. Fracturing and the generation of fine fragments
are facilitated by the fracture criterion and the application of
complementarity operations to the inter-particle connections. Our
experimental results demonstrate the efficacy of our framework in
realistically depicting a wide range of material behaviors, including
elasticity, plasticity, and fracturing, across various scenarios.
A Multi-species Material Point Method with a Mixture Model
Authors: Li Bo , Liu Shiguang
Published: June 2024

The material point method (MPM) has attracted more and more attention in
computer graphics. It is very successful in simulating both fluid flow
and solid deformation, but may fail in simulating multiple fluids and
solids coupling. We propose a unified MPM solver for multi-species
simulations. Compared to traditional MPM, we extend the degree of
freedom on background grid to store information of multiple materials,
so that our framework is able to deal with multiple materials well. The
proposed method leverages the advantages of MPM as a hybrid method. We
introduce the mixture model into the framework, which was the most
widely used for grid-based multi-fluid flows. This enables MPM to
capture the interaction and relative motion, and animates complex and
coupled fluids and solids in a unified manner. A series of experiments
are presented to demonstrate effectiveness of our method.
Key-Point-Guided Adaptive Convolution and Instance Normalization for Continuous Transitive Face Reenactment of Any Person
Authors: Xu Shibiao , Hua Miao , Zhang Jiguang , Zhang Zhaohui , Zhang Xiaopeng
Published: June 2024

Face reenactment technology is widely applied in various applications.
However, the reconstruction effects of existing methods are often not
quite realistic enough. Thus, this paper proposes a progressive face
reenactment method. First, to make full use of the key information, we
propose adaptive convolution and instance normalization to encode the
key information into all learnable parameters in the network, including
the weights of the convolution kernels and the means and variances in
the normalization layer. Second, we present continuous transitive facial
expression generation according to all the weights of the network
generated by the key points, resulting in the continuous change of the
image generated by the network. Third, in contrast to classical
convolution, we apply the combination of depth- and point-wise
convolutions, which can greatly reduce the number of weights and improve
the efficiency of training. Finally, we extend the proposed face
reenactment method to the face editing application. Comprehensive
experiments demonstrate the effectiveness of the proposed method, which
can generate a clearer and more realistic face from any person and is
more generic and applicable than other methods.

Published: June 2024

The operation of offshore vessels is directly related to the use of
flexible pipelines. The article describes in detail the analysis of
power, geometric, kinematic and technological parameters that affect the
main operational characteristics of these pipes during their operation
under water, in rough sea conditions and under wind loads. The article
describes the degree of dependence between loads on the pipeline and
velocity of the oncoming flow, the geometry of the pipe and the distance
to the rigid surface of the ship’s hull or the seabed. It was determined
how the flow velocity during parametric oscillations of the pipeline in
unrestricted flow and near the surface of the seabed affects the change
in its drag and lift coefficients. An estimate of operational limits of
flexible pipeline instability was obtained. On the base of changes in
distributed load, specific values for safe lengths of pipelines were
formulated. It has been stated that the probability of failure-free
operation of a flexible pipeline at a level of 0.99 is directly
determined by the frequency of its oscillation. Its numerical values
should always be at a level that does not exceed 3.7% of the frequency
of pipe dynamic oscillations.

Authors:   Yaba College of Technology, Yaba, Lagos, Nigeria., Adeniyi O. A
Published: June 2024

The proposed biocatalyst utilized in the microbial fuel cell (MFC) experiment demonstrated exo-electrogenic activity, with species such as Mycobacterium and Shewanella (Pseudomonas) sourced from sewer wastewater. Chemical parameters from the initial experimental trial did not comply with Environmental Protection Agency (EPA) limits. The total suspended solids (TSS) in the second MFC trial were the only parameter to meet the EPA threshold of 50 ppm, with influent and effluent concentrations of 96 ppm and 23.1 ppm, respectively. Consequently, supplementary treatment methods are required to achieve EPA discharge standards. The second trial indicated that the MFC setup effectively reduced metal concentrations, including Cr, Mn, Pb, and Zn, to levels that satisfy EPA surface water effluent discharge criteria.

Published: June 2024

Background: Acute kidney injury (AKI) is a significant challenge in healthcare. While there are considerable researches dedicated to AKI patients, a crucial factor in their renal function recovery, is often overlooked. Thus, our study aims to address this issue through the development of a machine learning model to predict restoration of kidney function in patients with AKI. Methods: Our study encompassed data from 350,345 cases, derived from three hospitals. AKI was classified in accordance with the Kidney Disease: Improving Global Outcomes. Criteria for recovery were established as either a 33% decrease in serum creatinine levels at AKI onset, which was initially employed for the diagnosis of AKI. We employed various machine learning models, selecting 43 pertinent features for analysis. Results: Our analysis contained 7,041 and 2,929 patients’ data from internal cohort and external cohort respectively. The Categorical Boosting Model demonstrated significant predictive accuracy, as evidenced by an internal area under the receiver operating characteristic (AUROC) of 0.7860, and an external AUROC score of 0.7316, thereby confirming its robustness in predictive performance. SHapley Additive exPlanations (SHAP) values were employed to explain key factors impacting recovery of renal function in AKI patients. Conclusion: This study presented a machine learning approach for predicting renal function recovery in patients with AKI. The model performance was assessed across distinct hospital settings, which revealed its efficacy. Although the model exhibited favorable outcomes, the necessity for further enhancements and the incorporation of more diverse datasets is imperative for its application in real- world.

A DIMENSÃO TELEOLÓGICA DOS DIREITOS HUMANOS: UMA INVESTIGAÇÃO JUSFILOSÓFICA
Authors: Santos Ednan Galvão
Published: June 2024

A temática dos direitos humanos logra repercussões em diversos campos epistemológicos. Interessam ao presente estudo duas áreas, em especial: o Direito e a Filosofia. Trata-se, com efeito, de uma pesquisa de Filosofia do Direito – ou, mais especificamente, de Filosofia dos Direitos Humanos. O problema aqui abordado é de ordem teleológica. Atine à finalidade dos direitos humanos. Pensar a finalidade dos direitos humanos implica pensá-los a partir de um ponto de vista teórico e prático, simultaneamente. Como se revela a dimensão teleológica dos direitos humanos? Eis o problema de pesquisa que rege os esforços da presente investigação. A análise da referida dimensão requer a consideração dos elementos formais e materiais que nela se apresentam. Destarte, o estudo da teleologia dos direitos humanos está, na presente pesquisa, bifurcado em dois âmbitos. A tarefa aqui assumida, portanto, consiste em abordar o campo da finalidade formal bem como a esfera da finalidade material dos direitos humanos. Os esforços epistemológicos resultariam incompletos se fossem exauridos em abordagens exclusivamente formais ou, de igual modo, no tratamento estritamente substancial dos direitos humanos. Somente a consideração dessas duas manifestações teleológicas enseja a suficiente compreensão do objeto de pesquisa aqui proposto.

The digital dominance in the transformation of modern education creates risks of crowding out the role of direct pedagogical technologies in educational progress. The global scientific landscape, formed on the basis of an analysis of publication activity on the issues of educational technologies in the world's leading scientific journals, demonstrates the current presence of dominant scientific research, and investigative and social interest in the technological equipment of the education sector in the world. By clustering keywords in publications on educational technology issues, the work identifies its meta-subject topics and provides their bibliometric and scientometric assessment. There are eight meta-subject topics in the field of educational technologies: “innovative pedagogical technologies”, “artificial intelligence”, “information and communication educational technologies”, “education effectiveness”, “mobile and media educational technologies”, “educational engineering”, “technologies in medical (nursing) education”, “information educational environments”. Associated with innovations in pedagogical technologies, understood as broadly as possible: from information (mediated) technologies to direct pedagogical ones, the meta-subject thematic area seems to be the most universal for interdisciplinary collaborations and favorable for the emergence of new solutions in the field of educational technologies. In this connection, this direction seems to be a donor for new thematic areas in the area under study.

Authors: Abd-Alhafiz Saif , M. Abbas Jasim
Published: June 2024

This paper presents the lateral static and cyclic response of a group of piles. The experimental program included this on a small scale using hollow piles of aluminium, and the sand rain method was employed to prepare the sandy soil with a 70% relative density. The case study is a laboratory model of a pile group 2x2 with spacing (i.e., 3D,5D, and 7D), and the proportion of embedded length to circular pile diameter (L/D) = 43. Different lateral cyclic loading ratios CLR of 60%, 80%, and 100% from pile group capacity are used. According to the experiments' results, the vertical and lateral piles' capacity and displacement are greatly impacted by the cyclic-loading variables, which include the number of cycles and the cyclic-load ratio. It can be concluded that when increases in CLR usually influence on pile group performance, and the lateral displacement increasing up to 66% for closely spaced piles. The pile group spacing affects the uplift displacement; the highest reach value (4.7mm) upward is 7D.
Numerical Simulation of Natural Convection in a Rhombic Enclosure with Heated Sidewall Coated with Metal Foam
Authors: A. Mussa Munther
Published: June 2024

A natural convection heat transfer inside rhombic square cavity partially filled with porous material have been numerically investigated. A constant heat flux has been applied to the left wall with a right wall kept in constant cold temperature while thermally insulated the top and bottom walls. Finite volume technique with Simple algorithm have been used to simulate the governing equations of fluid flow and heat transfer coupled with Darcy-Brinkman model to simulate the flow of the air inside the main cavity and the open cells of the porous media. Three factors were chosen to study their effects on the natural air velocity and the mechanism of the free convection inside the enclosure. The inclined angle of the sidewall of the rhombic (q = 90o, 80o and 70o), the thickness of the metal foam (t = 5 cm, 10 cm, and 15 cm) and the amount of heat flux (q = 150 to 600 w/m2). Copper metal foam with 0.9 porosity was chosen as porous media with open cell filled by air (Prandtl number =0.7) and 10 as pore density.  The results showed that using a layer of porous metal foam with open cells will increase the heat transfer rate. It was 41.3% enhancement when use 5 cm of porous media and 68% for 15 cm. Acute inclined angle will decrease local Nusselt number and led to form vorticities. Furthermore, high heat flux increased the average Nusselt number and improved the heat transfer rate.

Authors: Hassan Ali Surur , Khalid Jassim Ali
Published: June 2024

This study focuses on creating and analyzing pentagonal microstrip patch antenna arrays with one, two, and three elements for use in the 10 GHz X-band range, utilizing a metamaterial (MTM) superstrate technique. The MTM superstrate, composed of open circular ring cells, is tailored for a 1×2 array with a 10×8 cell arrangement covering an area of 45×36 mm². A 1×3 array has a 14×12 cell configuration spanning 63×54 mm². Positioned beneath the radiating elements and optimized with a quarter-wave transformer for impedance matching, the superstrate significantly enhances antenna performance. The MTM superstrate alters the radiation pattern and increases the gain by approximately 2 dB, demonstrating a gain improvement of around 27% for high-gain applications in the X-band frequency range. For the 1×2 array, the gain increases from 7.52 dB to 9.58 dB, representing a 27.38% improvement, while the input reflection coefficient improves from -48.6 dB to -58.068 dB, reflecting a 19.5% enhancement. Similarly, for the 1×3 array, the gain rises from 9.69 dB to 11.6 dB, showing a 19.73% increase, and the input reflection coefficient improves from -57.46 dB to -60.64 dB, indicating a 5.54% improvement and a good radiation efficiency of about 79.11%. This work involves designing and simulating the proposed antenna arrays using the Computer Simulation Technology (CST) software.

Authors: KEFENG Yuan
Published: June 2024

Subject. This article discusses the issues of construction of a socialist market economy in China, as well the problems of labor movement and a family budget formation.
Objectives. The article aims to analyze the changes in the structure of income, expenditure and investment of Chinese households in the initial period of the reform and opening-up policy (1979–1999), and justify the need to continue reforms.
Methods. For the study, I used a statistical analysis.
Results. The article finds that at the first stage of the reform and opening-up policy, household consumption and investment returned to normal gradually, becoming free from the negative impact of the planned economy. In modern China, the coexistence of different forms of ownership is allowed.
Conclusions. Economic reforms have laid the foundations for transforming household budget decision-making, but at the same time they have exposed the shortcomings of the citizen registration system hindering urbanization and the labor market development. Problems in the field of healthcare, education, financial organization, urban planning, and environmental protection have become more acute.

The use of point-of-care ultrasound in ambulances has recently gained attention as a valuable tool for enhancing patient care and diagnostic accuracy. This study aims to investigate the necessity of implementing point-of-care ultrasound in Saudi Arabia\'s ambulance services it worth to mentioning, there is no ultrasound in the pre-hospital services in Saudi Arabia . The findings of the study will provide important insights into the potential benefits of using point-of-care ultrasound in Saudi Arabia\'s ambulance services and inform policymakers\' decision-making. It is expected that results will also contribute to the broader adoption of point-of-care ultrasound in emergency medical care in other countries The research aims to anticipate the necessity of point of care ultrasound in Saudi's ambulance. The research was conducted retrospectively by collecting two separate sources of secondary data of 399 patients records. One is from the emergency medical services department of Royal Commission Health Services in Jubail (RCH). The second source is from RCH's hospital only from emergency department (ER). The study found that using ultrasound in prehospital patients has both diagnostic and therapeutic applications, and there is statistical significance to support its use. The applicability of point-of-care ultrasound (POCUS) varied depending on the type of call. Additionally, there was a correlation between the use of ultrasound and the ability to develop a suspected diagnosis in prehospital care. The data analysis also revealed that there was a variation in ultrasound test findings in the ER, with 100 out of 228 patients (43.86%) needing FAST conducted there instead of on the ambulance en route to the hospital. Out of the 106 cases (46.49%) with positive ultrasound findings, this information could be shared by paramedics to prepare the hospital for incoming patients and help reduce delays in patient care. We conclude the ultrasound is demand in the pre-hospital service of Saudi Arabia.
