Authors: García Montiel Emily , Marcelo López Serrano Pablito , Montiel Antuna Eusebio , Alejandro Soto Cervantes Jesús , Angelina Hernández Rodríguez Alma
Published: February 2025

A primary objective of forest certification is to ensure that forest management operations and administration provide opportunities for social, economic and environmental development. This mechanism was created to achieve forest sustainability through good forest management practices. It also helps to maintain transparent and accountable processes in forestry companies, as well as defined processes to promote the quality of operations. The emergence of new geospatial technologies derived from different remote sensing platforms is transforming forest monitoring and management in different ways. These technologies not only improve the efficiency of forest monitoring but also generate information that can contribute to the conservation and sustainable management of forest resources, so it is expected that the integration of information derived from these technologies, such as aerial forest biomass, as an indicator of forest sustainability and FSC environmental criteria and indicators assessment tools will facilitate certification through the detection of patterns and prediction of changes in forest ecosystems. This chapter highlights the importance of the global trend of continuous improvement in forest management processes, certification, and the incursion into new technologies, which together could represent important differences for sustainable forest management in Mexico.

Hamlin Hall: An American Educational Building Aesthetics on the Bosphorus Ridge
Authors: Öten Aliye
Published: February 2025

Hamlin Hall, a neoclassical style structure personally built by Robert College founder Cyrus Hamlin, stands out as a distinctive structure adorning the Bosphorus shores of Istanbul. Shaped by Hamlin’s educational approach that prioritizes vocational, technical and religious education covering every aspect of life, Hamlin Hall, a missionary, has an esthetic appeal with its location, function and design. The construction process of this structure is also remarkable in that Cyrus Hamlin, who had previously carried out educational activities in ready-made buildings and identified the deficiencies in those buildings, approached a structure in which he would implement the curriculum he created by blending science, social sciences and vocational education, including architecture and engineering. In this section, the Hamlin Hall building will be discussed with its history, function and style.
The Problems of Modern Cosmology, the Fine Tuning of Constants and Parameters, and the Notion of Time
Authors: Gaspar Yves
Published: February 2025

The Standard Hot Big Bang theory is successful from the observational point of view, yet a quite substantial list of unresolved problems still exists, resisting the endeavour of researchers who try to tackle these issues. Recent treatises claim that cosmology, and fundamental physics, currently faces a crisis. The initial conditions existing close to the Big Bang singularity, the value of the fundamental parameters of the Standard Model and of the constants of fundamental physics, as well as the form of the laws of nature remain without a satisfactory explanation. In this chapter, we will first review the proposal of Lee Smolin and Roberto Manabeira Unger, which essentially motivates a re-thinking regarding the notion of time, which would be considered as fundamental, irreducible and real. This suggested agenda for cosmology also considers the mathematical description of the world to be powerful indeed, but also that mathematics has immense limitations—it is claimed that mathematics cannot deal with phenomenal particularity as well as with time. We will subsequently present theoretical research done by the author, mostly at a heuristic level, which examines why fundamental aspects of mathematics would have difficulties when dealing with time and with the specificity of natural phenomena.
Effect of Indentation Depth on Tensile Shear Strength in Ultrasonic Welding of A1050 Aluminum Alloys and C1100 Oxygen-free Copper Alloys
Authors: Kim Young-Min , Kim Byeong-Jin , Hwang Insung
Published: February 2025

Ultrasonic welding technology is a joining method that utilizes localized frictional heat. Since the heat does not spread outside the joint, it is a method that can efficiently join two materials while minimizing thermal damage to the surrounding materials, making it an advantageous joining process for dissimilar materials. In this study, the effect of indentation on the ultrasonic welding characteristics of A1050 aluminum alloys and C1100 oxygen-free copper alloys was investigated. The changes in welding energy, tensile shear strength, and indentation depth were observed as the welding time increased while the applied clamping pressure and amplitude were fixed. The experimental results showed that the indentation and tensile shear strength of the ultrasonic weld were proportional within a certain range, but if the indentation depth becomes excessive, local damage to the material occurs, which actually reduces the joining strength.
Effects of Laser-Assisted Thermal Treatment on Self-Piercing Riveting (SPR) of DP 1180 and CFRP
Authors: Ju Wonjung , Kam Dong Hyuck , Kim Dongchoul , Kang Minjung
Published: February 2025

This study investigated laser-assisted thermal treatment to enhance the self-piercing riveting (SPR) joint quality for dissimilar material joining using high-strength DP 1180 steel and carbon fiber reinforced plastic (CFRP). Laser power, irradiation time, die geometry, and rivet geometry were considered as variables, and their effects were analyzed and compared. The results indicated that laser-assisted thermal treatment enabled the SPR process for high-strength steel. Increasing laser power and irradiation time expanded the heat-affected zone and reduced hardness to approximately 250 HV in the region where rivet flaring occurred, leading to martensitic transformation into ferrite and tempered martensite. Process variables significantly influenced SPR joint quality, including failure mode and fracture load. The lean die angle resulted in stable joint formation, while the steep die angle led to lower sheet detachment due to increased deformation demand. Longer rivets improved interlock formation and fracture load; however, the fracture mode shifted from rivet pull-out to CFRP failure. The results confirmed that laser-assisted thermal treatment enabled the SPR process for high-strength steel, and its effectiveness depended on die and rivet selection in ensuring robust SPR joints.
AI-Based Nondestructive Quality Evaluation of Friction Stir Welded Joints in Aluminum Parts for Electric Vehicles
Authors: Jeong Sanghyeok , Park Jooheon , Yoon Jinyoung , Kim Jaesung
Published: February 2025

In the manufacturing of electric vehicles, aluminum is widely used to enhance lightweight properties and heat dissipation in vehicle parts. However, aluminum is prone to issues such as internal pore formation and reduced strength compared to the base material after welding. Therefore, it is crucial to select an appropriate welding process based on the vehicle part's purpose, thickness, geometry and quality requirements. Friction Stir Welding (FSW) has become increasingly popular due to its effectiveness in reducing defects such as porosity, cracks, and thermal distortion. Various Non-Destructive Testing (NDT) methods, such as ultrasonic testing, radiographic testing, infrared thermography, and eddy current testing, have been utilized to evaluate the quality of FSW joints. However, research on real-time quality assessment using artificial intelligence (AI) in practical field applications remains limited. This study applies a high-resolution and high-reliability immersion-based A-scan automatic ultrasonic testing technique to detect micro-defects such as lack of penetration, tunneling, and kissing bonds in FSW joints and to acquire consistent data. Furthermore, using the acquired A-scan signal images, a real-time AI-based quality assessment program was developed to assess the acceptability of the FSW joint on-site.

Published: February 2025

This study investigated the optimization of additive manufacturing for high-hardness material (AISI M4) via preheating processes using Direct Energy Deposition (DED) technology. AISI M4 metal powder is a high-speed tool steel that is extensively employed in steel rollers and molds due to its exceptional wear and impact resistance The service life of products can be extended by depositing high-hardness materials such as AISI M4 onto their surfaces through the employing of 3D printing technology. Nevertheless, previous study has demonstrated that residual stresses can generate surface defects, including cracks, as a result of discrepancies in cooling rates during the deposition process of dissimilar materials. A preheating method was implemented to alleviate residual stresses during the deposition process in order to resolve the problem. The preheating temperature, laser power, and feed rate were the process parameters that were established in this study. The experiments were conducted at room temperature, 200°C, and 300°C. Deposition of a 40×20 mm size was demonstrated. In order to assess the deposition efficiency of the high-hardness material, the presence of defects (such as cracks) in the deposition cross-section and the deposition height was analyzed.

Support Factors and Mechanisms for Civil Servants’ Digitalization Readiness
Authors: Pulkkinen Jarmo , Suhonen Marjo , Leinonen Jaana
Published: February 2025

This study investigates organizational support factors and mechanisms that enable civil servants' digitalization readiness in municipal technical services. We define civil servants' digitalization readiness as an individual's ability and preparedness to utilize devices, software, digital materials, and remote work in their public organization duties. Despite increasing digitalization in public administration, there is limited understanding of how civil servants experience and perceive organizational support in the digitalization context, particularly in the technical sector, where digital transformation significantly impacts service delivery. Empirical data was collected through individual thematic interviews with civil servants in land use planning and construction supervision in 11 Finnish municipalities. We identified two mechanisms enabling civil servants’ digitalization readiness: (1) organizational resource mechanism, where socio-technical resources (e.g., infrastructure, peer support, IT support, and data management) affect work capabilities, and (2) creative digital tension mechanism, which activates through drivers including peer examples, skills assessments, state legislation, and perceptions of usefulness. Creative digital tension emerges as civil servants recognize gaps between current and desired capabilities, motivating learning and utilization of technologies. Our primary contribution to public administration literature is developing a conceptual framework for understanding organizational support mechanisms for civil servant digitalization readiness in municipal service production digital transformation.

Authors: Alifia Taarissa Nur , Deviastri Lily
Published: February 2025

This inquires about points to investigate the effect of item quality and benefit quality on repurchase eagerly, with shopper fulfillment serving as a intervening calculate. Information was accumulated through a survey, and the investigation utilized the Fractional Slightest Square Auxiliary Condition Modeling (PLS-SEM) strategy. The discoveries demonstrate that both item quality and benefit quality altogether impact repurchase eagerly through customer fulfillment. Particularly, item quality emphatically and essentially influences repurchase purposefully, as does benefit quality. Furthermore, item quality emphatically and essentially contributes to buyer fulfillment, whereas benefit quality too emphatically impacts buyer fulfillment. Customer fulfillment, in turn, features a positive and noteworthy impact on repurchase eagerly, and it somewhat intervenes the relationship between item quality and repurchase eagerly. So also, shopper fulfillment somewhat intercedes the impact of benefit quality on repurchase eagerly. Administrative Suggestions: This thinks about emphasizing the imperative part of both item quality and benefit quality in improving buyer fulfillment, which eventually drives repurchase eagerly. For supervisors, this underscores the significance of maintaining tall benchmarks in item offerings and benefit conveyance to cultivate client devotion.

Authors: Kuncoro Ignatius Bayu , Sihombing Pardomuan
Published: February 2025

This research examines the influence of Leverage, Liquidity, Profitability, and Institutional Ownership on Firm Value, with Environmental Performance as a moderating variable. The study focuses on coal sub-sector companies listed on the Indonesia Stock Exchange (IDX) from 2019 to 2023. Using purposive sampling, 14 companies were selected as research samples. Panel data regression analysis was employed. The findings reveal that Leverage and Institutional Ownership do not affect Firm Value. Liquidity negatively affects Firm Value, while Profitability has a positive impact. Environmental Performance does not directly influence Firm Value but moderates certain relationships. Specifically, Environmental Performance strengthens the effect of Liquidity and Profitability on Firm Value but does not moderate the impact of Leverage. The study’s managerial implications highlight the importance of fundamental factors such as profitability, leverage, and dividend policy in enhancing Firm Value. Additionally, companies should recognize Environmental Performance as a moderating factor that can reinforce certain financial influences. Management is encouraged to adopt sustainable business practices to improve both financial performance and environmental responsibility.

Inequalities for fractional derivatives via the Marchaud derivative
Authors: Webb Jeffrey R. L.
Published: February 2025

We study the Marchaud fractional derivative. We pay special attention to when the Marchaud fractional derivative is equal to the well-known Caputo or Riemann-Liouville fractional derivative. Conditions when this equality held were given in the interesting paper of Vainikko (2016). Several recent papers have used results from that paper in discussing inequalities that are useful in the study of stability. We have found some gaps in the proofs in the Vainikko paper but we give a proof of the most useful parts;in fact we also prove that equality holds under a more general condition. We use this equality to prove various inequalities for fractional derivatives, including a maximum principle, often under weaker conditions than previously given. In particular we prove strong versions of inequalities for differentiable convex functions that are useful in studying stability by Lyapunov's method.

Published: February 2025

This study aimed to statistically evaluate the PM10 and TSP time series data in the RGV, between 2008 and 2017, verifying whether the series of each pollutant are generated by the same stochastic process. For that, the tests proposed by Coates and Diggle (1986), by Quenouille (1958) and the series difference procedure developed by Silva, Ferreira and Sáfadi (2000) were used. PM10 time series for Laranjeiras (E1), Carapina (E2), Jardim Camburi (E3), Enseada do Suá (E4), Vitória (E5), IBES (E6) and Cariacica (E8) stations were compared two by two, and for TPS time series of stations E3, E4, E5, E6 and E8 the same was done. Results indicate that, for a 5% significance level, stations E2, E3, E4, E5 and E6 for PM10 and, E3, E4, E5 and E6, for the TSP, present time series generated by the same stochastic process. Therefore, is considered that, the results obtained are indicative of the need to reformulation the initial RAMQAr project, which, if added to a pollutant dispersion study, can guarantee the network coverage area expansion, with emphasis in the existing stations re-spatialization, aiming to improve their data representativeness and installation of new stations in places still lacking monitoring.

The first artificial quantum neuron models followed a similar path to classic models and they work only with discrete values. Here we introduce an algorithm that generalizes the binary model manipulating the phase of complex numbers. We propose, test, and implement a neuron model that works with continuous values in a quantum computer. Through simulations, we also demonstrated that our model may work in a hybrid training scheme utilizing gradient descent as a learning algorithm. This work represents another step in the direction of the practical use of artificial neural networks efficiently implemented in near-term quantum devices.

Lipid oxidation in meat and its derivatives causes gradual degradation of sensory and nutritional qualities, impacting consumer acceptance of the product. To delay and/or reduce this deterioration and extend shelf life, antioxidant substances are often used, predominantly synthetic ones. However, synthetic antioxidants can have carcinogenic properties, leading consumers to prefer natural products. Consequently, numerous studies have been conducted to replace synthetic antioxidants with natural alternatives. The purpose of this study is to assess the most widely used sources of natural antioxidants in meat and its derivatives, identify the main chemical groups associated with them, and examine the types of extraction methods used. Research in the Scopus and Web of Science databases yielded 35 relevant articles. It was observed that 29% of the published studies applied natural antioxidants to chicken meat, while 71% applied them to derivatives. The chemical groups most commonly associated with natural antioxidants were phenolic and flavonoid compounds. These antioxidants were used in various forms, such as extracts, powders, essential oils, and encapsulated oils. Additionally, it became evident that the concentration of natural antioxidants applied to chicken meat and its derivatives must be limited to avoid altering sensory attributes. Natural antioxidants have been shown to positively affect lipid oxidation inhibition, making them a viable alternative to synthetic antioxidants.

The productive sectors seek to rethink their activities to minimize their negative contribution to the climate, including solid waste generated by different areas. The use of waste from a productive sector in another productive sector can minimize the consequences of the current environmental degradation. In this study, the fine aggregate (sand) was partially replaced with diatomaceous earth waste from brewery filters without extensive treatment in concrete production. Concrete dosages were prepared with 0% (reference), 2.5%, 5%, and 10% w/w/replacement of diatomaceous earth waste and evaluated for axial compressive strength, diametral tensile strength, modulus of elasticity, specific mass, water absorption, and void ratio. The one-way analysis of variance (ANOVA), with a significance of 5%, tested the differences, followed by the Tukey-Kramer test for pairwise comparisons. All mixtures with replacements were significantly different from the reference mixture, but the results showed that it is possible to use the waste as a partial substitute for sand in the non-structural concrete production. Thus, it is possible to decrease the amount of natural sand and, at the same time, reduce the environmental liabilities of the brewing industry, creating some possibilities in the management of solid waste and mitigation in the exploitation of non-renewable natural reserves.

Este trabalho aborda a metodologia Bayesiana para solucionar um problema inverso de transferência de calor em um dissipador térmico com microcanal. O problema direto envolve o cálculo do perfil de temperatura na placa, assim como a temperatura do fluido que escoa no microcanal, através de um modelo matemático simplificado do sistema físico em questão. O problema direto foi resolvido numericamente através do método de diferenças finitas explícito. O problema inverso em questão consiste em estimar os coeficientes de transferência de calor por convecção do sistema, no contexto da abordagem Bayesiana. O método de amostragem de Monte Carlo via Cadeias de Markov Transicional foi utilizado para amostrar a densidade de probabilidade a posteriori dos parâmetros do modelo. A metodologia proposta foi avaliada a partir de simulações numéricas envolvendo dados de temperatura corrompidos com ruído aditivo e diferentes modelos para os coeficientes de transferência de calor estimados. Também são apresentadas análises numéricas considerando dados observados de temperatura gerados a partir de um modelo completo implementado no software COMSOL Multiphysics. Os resultados apresentados mostram que a metodologia proposta foi capaz de estimar os coeficientes de transferência de calor nos diferentes cenários considerados.

Published: February 2025

Let n ≥ 3 be an integer, ζn a primitive nth root of unity, and K the cyclotomic field Q(ζn). In this paper, we present an explicit description of the integral trace form TrK(αxx), where α, x ∈ K and x is the complex conjugate of x. Furthermore, we present constructions of algebraic lattices via the twisted canonical homomorphism with optimal center density in dimensions 2, 4, 6, 8 and 12, which are rotated versions of the lattices Λn, for n = 2, 4, 6, 8 and K12.

Esta pesquisa tem por objetivo analisar os esquemas cognitivos associados ao conceito de integral apresentados por estudantes universitários na resolução de problemas interdisciplinares de Cálculo e Física. Tendo a teoria APOS como suporte teórico, estabelecemos a decomposição genética do conceito de integral e selecionamos quatro problemas que envolvem conceitos da Física e que são resolvidos utilizando os esquemas do conceito de integral. O estudo, de abordagem qualitativa, foi desenvolvido junto a 30 estudantes de um curso de Engenharia, de uma instituição pública federal de ensino superior. Os dados foram coletados por meio da produção escrita dos estudantes na resolução dos problemas propostos e, analisados seguindo as construções e os mecanismos mentais estabelecidos de acordo com a teoria APOS, e apresentados, pelos estudantes na resolução dos problemas. Dos principais resultados obtidos, evidenciamos que foi fundamental a utilização de problemas interdisciplinares do Cálculo com a Física para a construção de esquemas cognitivos sobre a integral pela maioria dos estudantes. Isto trouxe motivação e interesse aos estudantes, um fator que provavelmente contribuiu para o desenvolvimento dos mecanismos mentais que possibilitou a construção dos conceitos.

Published: February 2025

Short-term weather prediction systems that rely on radar information, known as nowcasting, involve multiple stages of numerical computation and visualization. The algorithms utilized encompass geometric transformations, statistical analysis, image processing, scalar and vector field calculations, and numerical computations based on various mathematical models. Current computer software used for nowcasting, which depends on data and images, requires a deep understanding of fundamental geometry, calculus, algebra, and various mathematical principles from both users and developers. This paper aims to provide a concise and straightforward overview of the process of handling weather radar data for visualization and nowcasting, while also delving into the mathematical principles underpinning these techniques. As a result, the application of mathematics topics covered in undergraduate courses was presented, in the context of their practical use in precipitation and severe events nowcasting systems.
