Published: January 2025

Model quality and computational resources must be carefully balanced in numerical simulations due to the high computational cost that three-dimensional models pose. This is inherently true in the oil and energy industry, where reservoir modelling and complex real experiments are required, in which inaccuracies have a direct impact on financial outcomes. Properly used, one-dimensional simulations yield significant technological and financial benefits by reducing simulation runtime, allowing more efficient operations, and faster and more accurate decision-making. As a result, wherever possible, models with lower dimensionality are preferred. This work aims to analyze the feasibility and effectiveness of the dimensional reduction of three-dimensional to one-dimensional models for unsteady-state core-flooding experiments. For that, 1D and 3D multiphase flow on porous media simulations were performed using the Black Oil IMEX software to verify the variability of oil production volume, saturation profiles, and differential pressure numerical responses. According to the results, the oil production volume and pressure differential are not affected by the dimensionality of the problem in homogenous cases. On the other hand, it is found that when dimensionality is reduced, heterogeneities lead to different outcomes in terms of pressure differential and oil volume production, which, in that case, may compromise dimensional reduction.

Published: January 2025

Geological faults are present in several regions in subsurface. For conventional reservoir engineering in the oil and gas industry, such faults are considered as impermeable surfaces responsible for reservoir compartmentalization. However, seismic and field observations show that faults are not surfaces but volumes composed by two regions: the fault core and the damage zone. While the fault core accounts for the fault sealing, the damage zone can have different impacts for fluid flow depending on the geological structures present around the fault. Porous host rocks such as sandstones are prone to trigger deformation bands which can significantly reduce the permoporous properties of the rocks, acting as barriers for fluid flow. On the other hand, stiff rocks with reduced porosities are prone to develop fracture networks in the damage zone, creating preferential flow paths. Therefore, the consideration of fault damage zones and their corresponding properties are important for reservoir modeling in order to develop suitable production strategies, in particular for enhanced oil recovery. In this kind of applications, water is injected into the reservoir aiming at raising both the reduced reservoir pressure and the oil production. In this study, we consider a three-dimensional reservoir model that includes a water injection well, an oil production well and fault damage zones between the wells. Then, different scenarios are analyzed considering the fault damage zone composed either by deformation bands or fracture networks using equivalent continuum approaches. For such purpose, power-laws based on deformation band density and fracture intensities around the fault core are used to define the permeabilities corresponding to the damage zone. The numerical results show that the presence of the damage zone generated around a normal fault changes the water propagation speed, affecting the oil recovery efficiency. Furthermore, the obtained results also contribute for a better understanding the dynamic behavior of flow through these geological structures.

Published: January 2025

Heterogeneities within reservoir cores significantly influence fluid flow behavior, potentially causing premature rupture and distorting experimental outcomes. Neglecting to account for these heterogeneities when incorporating relative permeabilities into reservoir simulation models can render such models non-representative of real field conditions, thus impacting field performance predictions. Predicting behavior resulting from random heterogeneity distributions becomes challenging. Therefore, it is crucial to mitigate these effects by studying local heterogeneities to better understand their influence at larger scales. This study leverages CMG®, a well-established petroleum reservoir simulation software, to model lithology based on outcrop data. Synthetic heterogeneous plugs were simulated under various scenarios to assess their impact on flow parameters during SCAL experiments. Both single-rate and experiments with multiple flow rates were conducted on 3D plugs. The analysis focused on heterogeneity variability, examining net production and pressure differentials. Additionally, the study investigated how heterogeneity affected experiments with varying flow rates. The results highlight notable impacts observed through spot analysis of plugs representing smaller regions. Experiments with multiple flows demonstrated greater sensitivity to heterogeneity compared to prolonged experiments with a single flow. These findings suggest that such influences would be exponentially amplified in large oil fields, as supported by the presented data

Published: January 2025

In engineering, professionals must understand the properties and performance of a specific material before exposing it to the conditions of a specific application. In this context, engineers and scientists have been searching for materials with peculiar properties that withstand extreme adversities, responding with high performance to the challenges imposed. Heat transfer studies are essential and have been extensively explored due to their relationship with our daily lives, such as in thermal insulation systems and electronic device applications. Over the past few decades, computational models have been used and have achieved excellent results in studying and predicting material properties. The Finite Volume Theory (FVT) was first introduced in 2003, using Cartesian coordinates. It establishes the continuity and boundary conditions through the faces of the discretized analysis domain in a surface-averaging sense. The theory also satisfies the flux balance equations in the subvolumes in a volume-averaged sense. The temperature fields are approximated by second-degree polynomials that are expressed in the local coordinates of the subvolumes. Despite the versatility and efficiency of numerical methods, the long processing time has led researchers to look for ways to improve the performance of computational models. One solution is to use computational language tools that simplify operations and reduce code execution times, even for large-scale problems. This study aims to present an efficient code that uses MATLAB computational resources to analyze two-dimensional heat transfer by applying the finite-volume theory.

Authors: Raniere Henrique Pereira Lira  , Karlisson André Nunes da Silva
Published: January 2025

Thermal comfort in buildings has been researched through new materials that reduce energy consumption. Lightweight concrete appears as an alternative for civil construction as it presents particular characteristics such as lower specific mass and a higher thermal insulation capacity than conventional concrete. The objective of this work was to evaluate the heat transfer process in concretes with different densities using computational modeling. A mathematical model for heat transfer in concrete blocks with different densities was implemented and all simulations were carried out using the Ansys Student 2023 R2 program. Normal Density Concretes (CDN) and Foamy Cellular Concretes (CCE) were produced with two different proportions, one with 10% foam (CCE10) and the other with 20% foam (CCE20), using air-entraining additives to generate foam. The simulation results presented a good representation of the heat transfer phenomenon when compared with the experimental results. They showed that the addition of foam to concrete reduces thermal conductivity, improving energy efficiency in buildings, demonstrating the potential of these materials for applications in civil construction.

This study evaluates the use of a retrievable heating tool, deployed via slickline, for dissociating hydrate plugs within a subsea well Christmas Tree (WCT). The focus was on a specific hydrate plug located within the WCT bore, analyzed through multi-phase Computational Fluid Dynamics (CFD) simulations enhanced by adaptive mesh refinement techniques. Findings indicate that a power setting of approximately 3.1 kW is optimal, effectively balancing operational efficiency with safety. This power level maintains temperatures just below the critical threshold of 120°C and achieves complete hydrate dissociation in around three hours. The investigation underscores the importance of precise power calibration and management of its associated uncertainties to ensure the integrity and effectiveness of hydrate dissociation operations.

Decarbonization involves the intensive use of renewable energy to obtain a sustainable energy matrix. Brazil has an electrical matrix strongly anchored in renewable sources, historically in hydraulic energy, and more recently, in solar, photovoltaic, and wind sources. The latter are stochastic and, therefore, have strong restrictions on their insertion into the matrix in a broad and dominant manner. Due to these limitations, excess supply can be used to produce green hydrogen and even methane in a process called methanation (chemical reaction between CO2 and H2). The use of electrical energy from renewable sources for the production of fuels is known in literature as power-to-gas. These fuel vectors (H2 and CH4) can be used directly to generate energy or can be mixed with natural gas to enrich it in terms of energy and potentially reduce emissions. This study evaluates the effect of enriching mixtures of natural gas and hydrogen on CO, CO2, and NOx emissions, considering combustion applications in Gas Turbines. The analyses were numerical and involved the use of a thermodynamic combustion model with chemical equilibrium. The chemical equilibrium model is based on chemical equilibrium constants and assumes that the reactants and products are ideal gases. The volumetric fractions of H2 in the mixture from 0 to 30% and the effect of the combustion pressure were investigated. The pressure was varied according to the application chosen. Gas turbines are part of the combined power cycles, and plants can operate with gas turbines of different pressure ratios according to the model, power, and manufacturer of the Gas Turbine. The analyses focused on medium and large gas turbines, and the chosen pressure range was 12:1 to 24:1.
Numerical analysis of trajectory and range for different boattail angles of an artillery projectile
Authors: Andre Luiz Tenorio Rezende  , Rodrigo de Azevedo Rodrigues Paulo  , Victor Santoro Santiago
Published: January 2025

This article aims to compare the different trajectories of a 155 mm artillery shell when changing the angle of its trailing edge, also known as boattail. To this end, an iterative numerical analysis computer program was developed where the differential equations of the projectile trajectory are solved with 4 degrees of freedom, that is, through the modified mass-point method. When solving the system of differential equations, the 4th order Runge-Kutta method is used. The trailing edge angle is a geometric characteristic that is directly related to the base drag force experienced by the ammunition. Furthermore, the magnitude of the drag force has a great influence on the firing range and this, in turn, is of great relevance for the development of a projectile. Drag coefficients for Mach numbers between 0.5 and 3.0 are obtained using the PRODAS ballistic calculation software. Each boattail angle generates a curve of drag coefficients as a function of Mach number. These values are then used as input data in the source code and thus the simulation can be performed. The results obtained are validated by existing data in the literature and highlight variations in trajectories, showing that the maximum range can be obtained by determining an ideal boattail angle.
Thermoregulation of integrated photovoltaic panels with bio-based phase change materials

Published: January 2025

Although photovoltaic (PV) technology has achieved significant advancements in harnessing irradiation to generate electricity, different questions remain open, especially regarding the adverse effects of high temperatures on the PV system. As the temperature of PV panels increases, their energy-conversion efficiency decreases, reducing the overall electricity production. High temperatures also accelerate the degradation of the PV panel, leading to shorter operational lifespans and higher maintenance costs. Hence, reducing the PV panel temperature throughout the day can prevent thermal degradation and increase its efficiency. In the present work, we numerically evaluate the thermal behavior of a PV system integrated with a phase change material (PCM). The numerical model uses the Finite Volume Method to solve the conservation equations of mass, momentum, and energy. A 3D transient thermal model incorporating the PCM enthalpy formulation was developed to analyze the PV panel temperature. The thermal model considers the energy transfer by conduction, convection, and radiation throughout the day. A mean absolute deviation of 3% was obtained for the PV panel temperature by comparing it with experimental data available in the literature. After the numerical model validation, the PCM was changed to a bio-based PCM (bioPCM) consisting of la uric acid, whose melting point is relatively high (from 4446 °C), allowing its use in regions of high solar incidence. Furthermore, it has a high latent heat of fusion, being chemically stable and non-toxic. Using the proposed bioPCM, a temperature reduction of 9 °C was obtained, increasing the energy production, on average, by 9% compared to a conventional PV without PCM. Overall, using the proposed bioPCM can avoid excessive losses of energy-conversion efficiency under high irradiance conditions and extend the lifespan of photovoltaic panels.
Analysis of local buckling in steel Rectangular Hollow Section via Lumped Damage Mechanics
Authors: Leonardo Andrade Bispo Silva  , Higor Sérgio Dantas de Argôlo  , David Leonardo Nascimento de Figueiredo Amorim
Published: January 2025

This paper presents a lumped damage model to analyse local buckling in steel Rectangular Hollow Section (RHS). In this model, the nonlinear and damage effects of the planar frame element are concentrated in plastic hinges located at the ends of the element, significantly reducing the computational cost of the analysis. Thus, plasticization is represented by the formation of plastic hinges, while local buckling is described by the addition of a damage variable to these hinges. The analysis adopts a step-by-step procedure to consider geometric nonlinearity, solving the problem sequentially and considering the change in the geometry of structural elements. To evaluate the accuracy of the model, the numerical results were compared with experimental results, in which steel RHS were subjected to compressive axial force with monotonic bending moment loading. The results indicate that the numerical model presents satisfactory behaviour in relation to the experimental results.
Homogenised damage model for concrete
Authors: José Julio de Cerqueira Pituba  , Dannilo Carvalho Borges
Published: January 2025

This work deals with numerical simulation of the mechanical behaviour of concrete using a homogenised damage model based on the concept of Representative Volume Element (RVE). The RVE is composed of phases with different mechanical behaviours leading to heterogeneous characteristics on the microstructure level. We adopt a simple damage model capable to simulate the behaviour of the cement paste and transition zone while the aggregates are modelled as linear elastic material. To perform the numerical analysis, a based homogenisation technique is used to obtain a damage model that represents the macromechanical behaviour of the material. Results show the capabilities of the model to capture complex phenomena including a comparison with experiments tests performed in concrete specimens.

Authors: Daniel Victor da Cunha Teles  , David Leonardo Nascimento de Figueiredo Amorim  , Edson Denner Leonel
Published: January 2025

The use of ultra-high-performance fibre-reinforced concrete (UHPFRC) has significantly increased in the recent years. However, the accurate mechanical behaviour modelling of this complex material is still a challenge in the present. Because the materials high load-bearing capacity and the presence of fibbers, this type of problem experiments large displacements before the failure. In this study, the material damage description has been performed by the Extended Lumped Damage Mechanics. Additionally, an approach based on the nodal positions of the Finite Element Method has been utilised, which makes the formulation geometrically exact. Thus, this study evaluates the failure of structures composed of UHPFRC, accounting for the effects of material and geometric nonlinearities computed by the Extended Lumped Damage Mechanics and the Finite Element Method based on positions, respectively.

Authors: Idrees Muhammad , Tahir Muhammad , Afridi Muhammad Asim
Published: January 2025

In this paper, a new index of digital financial inclusion is developed using the access, usage, and availability dimensions of digital financial inclusion. The two-stage principal component analysis is applied to develop an index using the IMF financial access survey data for 68 countries from the year 2014-2021. The countries are further divided into four groups using World Bank income classifications. The new index proposed in this study covers 68 countries based on continuous data from the IMF FAS survey. The index is a contribution to the ongoing literature on digital finance and will be used as a device to measure digital financial inclusion. The results show that the high-income countries are technologically advanced and have a higher ranking in digital financial inclusion while the upper middle (UMIC) and lower-middle-income countries (LMIC) are making steady progress with respect to the digitization of the financial sector while low-income countries are less digitally inclusive due to lack of digital infrastructure. Moreover, they have the problem of a lack of digital finance data. International financial institutions i.e. The World Bank, IMF, and national financial institutions such as central banks should work towards a vibrant and digitally inclusive financial sector.

Authors: Sarkar Sukanta
Published: January 2025

The objective of the study is to examine the current status of non-performing assets of banking sector of India. It has found that non-performing assets is a bigger challenge of our banking sector. Such asset is the burden in any financial institution. It exists in more or less in any type of banking institution. Gross and net non-performing assets of scheduled commercial banks are declining since 2018-19. In scheduled commercial banks, public sector banks have the higher non-performing assets then the private bank, regional rural banks and foreign banks. Rural Co-operative Banks has higher non-performing assets then the urban cooperative banks. Non-performing assets affect bank’s profitability, and revenues. Due to the recession and slowdown in demand, companies are unable to pay debts. This has led to debt accumulation and increased non-performing assets. The Reserve Bank of India has taken various measures to address the non-performing assets problem. Measures related to management processes, technological integration and specific business strategies aimed at immediate reduction and long-term adaptation.

Published: January 2025

El presente estudio tuvo como objetivo desarrollar y evaluar un prototipo de videojuego educativo, "Aventura Fraccionaria", para reforzar el aprendizaje de las operaciones con fracciones en estudiantes de quinto grado de primaria. Se utilizó un diseño pre-experimental con un grupo control y un grupo experimental, aplicando pruebas antes y después de la intervención. Los resultados estadísticos indicaron que el grupo experimental tuvo mejoras significativas en operaciones de suma y resta, con un valor de U de Mann-Whitney de 196.000 y un p-valor de 0.006, lo que confirma diferencias significativas en comparación con el grupo control. En operaciones más complejas como multiplicación y división, las mejoras fueron menos significativas, con un valor de U de 260.500 y un p-valor de 0.257. Se concluye que la gamificación, a través del videojuego educativo, es una herramienta eficaz para mejorar el aprendizaje de las fracciones y aumentar la motivación de los estudiantes, aunque es necesario ajustar el prototipo para mejorar el rendimiento en operaciones más avanzadas.

Machine learning applied to arbovirus genome classification
Authors: Barbosa Luiz Carlos Bertucci
Published: January 2025

The aim of this study was to evaluate the use of machine learning for rapid classification of arbovirus genomes. Initially, genomic sequences of 17 distinct arboviruses were collected from the National Center for Biotechnology Information database. Genomic sequences of arthropod-specific virus were also collected to compose a separate class, representing a “non-arbovirus” group. Subsequently, the sequences were transformed into canonical k-mer frequencies and used to train supervised classification algorithms such as multinomial logistic regression, decision tree, k-nearest neighbors, support vector machine and multilayer perceptron. Six distinct k-mer values within a range of 1 to 6 were also evaluated. Using 10-fold cross-validation as an evaluation method, the supervised model created with multilayer perceptron and k-mer value 6 presented the best average accuracy (98.8%). In order to evaluate the generalization capacity of the best model obtained, classifications were made using genomic sequences not present in the training database. The results of the classifications generated were evaluated by the metrics of accuracy, precision, recall and f1-score, obtaining values of 98.5%, 98.3%, 98.2% and 98.2%, respectively. Finally, the best model obtained was incorporated into a web application, which allows the input of virus genomic sequences and their classification. The application is freely available for use at https://arbovirusclassifiercanonicalkmer-8fndyh3tsxrftmr66jmpas.streamlit.app.

A microrregião do Baixo Parnaíba maranhense, com uma expressiva concentração de poetas, se vislumbra como um campo fértil para se melhor compreender dinâmicas culturais para potencializar o turismo literário local. Face à escassez de pesquisas a esse respeito, este estudo objetiva, analisar, em profundidade, a relação de sentidos estabelecidos entre cultura, patrimônio cultural e poesia na percepção de poetas do referido contexto, tido como periférico. A investigação se caracteriza como descritiva e exploratória, de abordagem qualitativa. Um roteiro semiestruturado de questões, elaborado com base na literatura, foi o instrumento de coleta de dados utilizado. Entrevistas em profundidade foram realizadas com dois poetas do Baixo Parnaíba maranhense, em 08 de março de 2024. A análise do conteúdo das entrevistas foi confrontada com a literatura. Das análises, apreendeu-se que os poetas entendem a cultura como a compreensão da própria história humana, a forma como os indivíduos reagem aos estímulos sentidos e interpretados ao longo da vida. Reconhecem a necessidade de sensibilização e valorização do que torna o contexto e seu povo, singulares. Como principais dificuldades percebidas em sua atuação artístico-profissional, os poetas sinalizaram a escassez de recursos financeiros e de conhecimento técnico operacional face ao desejo de institucionalizar seus saberes poéticos, na forma de negócio em constante expansão mercadológica. As produções poéticas analisadas agregam à experiência turística uma perspectiva educacional em conexão com o imaginário coletivo local, que se constitui em patrimônio, se não oficial, almejado, como parte do processo da esperança ativa em favor da pluralidade cultural e das solidariedades comunitárias.

Published: January 2025

Green synthesis approaches for the synthesis of nanomaterials and their different uses have been researched and garnered the interest of researchers in recent years (1-5). One excellent instrument for the introduction and advancement of nanotechnology is the green synthesis of noble metal nanoparticles. Because no hazardous or toxic chemicals are used during the plant-mediated synthesis process, also known as phytosynthesis, it is sometimes referred to as "green synthesis" (6, 7). In order to control the morphology, size, and stability of synthesised nano-sized structures, metallic nanoparticles can be prepared using a variety of synthesis techniques, including biological, physical, chemical, and others. However, the most intriguing synthesis method is the one for green metallic  anoparticle synthesis. Plant extract-based green synthesis techniques have gained a lot of attention because they are both economical and environmentally friendly (8-10) and because a variety of abundant and diverse biomolecules function as reducing and capping agents (11, 12). Modifying the morphology, shape, size, surface to volume ratio, and composition of nanoparticles (NPs) is a crucial step towards achieving improved physical, chemical, and biological properties for desired applications in various fields, including electronics, household appliances, cosmetics, agriculture, and pharmaceuticals (13-17). Green synthesis methods facilitate this process. The safe and environmentally benign character of phytosynthesized silver nanoparticles (Ag NPs) makes them an attractive option for usage in a wide range of applications. Researchers are constantly looking for less dangerous, manageable, effective, large-scale manufacturing, and environmentally friendly synthesis techniques for nanotechnology advancements and their effects on biological things (18-21). Ag NPs are among the metals that have drawn the most attention from researchers because of their unique physiochemical characteristics and exciting potential uses in biomedicine (22-27). In order to lessen microbial contamination, the scientific community is making use of silver nanoparticles (Ag NPs) in nanomedicine and in combination with other biomaterials. Because of these nanoparticles' surface plasmon resonance feature, they have also been investigated for bio-imaging applications (28).

Published: January 2025

Reform of the military justice system (criminal law enforcement) is essentially part of the idea of law reform. Legal reform includes not only "legal substance reform" and "legal structure reform", but also "legal culture reform". Therefore, the reform of the military criminal law system must also be accompanied by the renewal of the military legal culture, which includes, among other things, the renewal of the cultural aspects of legal behavior and legal awareness related to "military culture" and the renewal of the aspect of military legal education/science. So, "legal behaviour, legal, science and legal education reform" is also needed. This research will discuss Military Justice Reform in Indonesia, by conducting a comparative study with the existing military justice systems in various countries. This article concludes that the prospect of the position of the military court in Indonesia after the administrative, organizational, and financial fields are in the Supreme Court will make the military court better and more independent. The administration and organization will be more well organized in accordance with other courts.

The development of communication and information technology currently has a major impact on the pattern of public complaints about public services which in the era of digital democracy are inseparable from the dynamics of regional government. The presence of regulations regarding public services through Law Number 25 of 2009 and various derivative regulations in the implementation of regional government is an important part of moving towards a more democratic life. This study aims to discuss the policy of the South Sumatera Provincial Government in handling public service complaints through electronic communication media in the era of digital democracy from a political and public policy perspective. The study uses a combination of normative legal methods and secondary data analysis. The study concludes that politically, handling public complaints about regional government services is a positive thing. In the context of digital democracy and the quality of public services, the response of the regional government to public complaints is a measure of good governance. The issuance of Regional Regulation Number 3 of 2013, Governor Regulation Number 26 of 2016, and Governor Regulation Number 9 of 2022 are concrete manifestations of public policy. As a product of the political process, this is substantively related to public services and public complaints in the digital era. The existence of an electronic complaint channel regarding public services opens up space for increasing public awareness of their rights. Political life will be more democratic when communication between the government and the people runs functionally. There are several regional policy substances that need to be improved.
