Effects of metakaolin and waste tire aggregate on the properties of pumice-based lightweight geopolymer
Authors: Bayraktar Oğuzhan Yavuz , Jamal Ahmed Salah , Öz3 Ali , Shi Jinyan , Bodur Burak , Kaplan Gökhan
Published: February 2025

The lightweight geopolymers (LWGPs) were prepared using fly ash (FA) and pumice aggregates, and their sustainability was enhanced by recycling waste tire aggregates (WTAs). The results show that substituting pumice aggregate with WTA reduces the density of LWGP and improves its fluidity. However, this substitution is detrimental to the development of the strengths and durability of LWGP, but it is beneficial to the improvement of thermal insulation performance. The further use of metakaolin to replace FA enhances the performance of WTA-based geopolymer, especially improving its mechanical properties and durability. When 10% of FA is replaced by metakaolin, the compressive strength of LWGP increases by 5.5%–40.4%, and the residual strength after sulfate attack, freeze-thaw cycle and high temperature treatment is significantly improved. Using a small amount of metakaolin effectively mitigates the negative impact of WTA on the performance of LWGP. Utilizing WTA effectively reduces the total cost and carbon emission of LWGP production. Compared to plain LWGP, the mixtures with 15%–45% WTA exhibit a relative reduction in cost and carbon emission by 4.5%–13.4% and 1.3%–4.0%, respectively. Although the inclusion of metakaolin escalates both the cost and carbon emissions, its incorporation significantly enhances the overall performance of LWGP.

Authors: Das Turan , Efe Yusuf , Karademir Ibrahim , Unal Okan
Published: February 2025

In this study, the effect of Severe Vibratory Peening (SVP), a surface severe plastic deformation method, on the microstructure and mechanical performance of AISI 8620 steel was investigated. Specimens were treated with SVP for 30 minutes, 1 hour, 2 hours, and 4 hours. Microstructural analysis revealed that all treatments induced a plastic deformation layer on the surface, with layer thickness increasing with longer treatment durations. Surface microhardness increased by 22% relative to untreated specimens, with improvements observed up to approximately 85 μm beneath the surface. Under a 5 N load, wear volume loss showed no significant difference between treated and untreated specimens; however, at a 15 N load, long-term SVP treatments (1, 2, and 4 hours) resulted in decreased wear loss compared to the untreated condition. The enhanced hardness from plastic deformation overcame the negative effects of increased surface roughness on wear resistance. Moreover, the coefficient of friction decreased with increasing load in the treated specimens, although untreated specimens exhibited the lowest friction overall. Corrosion resistance improved following all SVP treatments, with the highest resistance observed in the 30-minute treatment and the lowest in the untreated specimen.
Probabilistic and FEM hydro-mechanical coupling analysis of rainfall-induced slope instability
Authors: Zhao Tao , Thusyanthan Indrasenan
Published: February 2025

The random field theory coupled with a FEM hydro-mechanical model was employed to analyse slope responses under rainfall, with a particular focus on post-rainfall behaviour. This study uniquely analysed the heterogeneity of soil strength and permeability through the application of random field theory, providing a novel perspective on its impact on slope stability. Numerical modelling under varying rainfall intensities revealed that the factor of safety (FoS) decreased with prolonged rainfall, particularly at higher intensities. Post-rainfall behaviour varied for different rainfall events, that gentle and moderate rainfalls led to a gradual decline in FoS due to water infiltration, while heavy rainfall allowed recovery through drainage, and extremely heavy rainfall triggered immediate failure. A novel finding is that post-rainfall water seepage can govern slope stability under extreme rainfall conditions. At failure, the surface layer of a fully saturated slope lost clay suction and exhibited concentrated plastic shear strain at its base. Weak zones with interconnected high-permeability channels significantly influenced slope stability by facilitating water infiltration. Probabilistic analysis further showed that the FoS at the end of simulations typically ranged from 1.1 to 1.4, with a recommended 5th percentile value of 1.1 for slope designs.
Microscale investigation of bentonite distribution in pore spaces of sand after infiltration of stabilising solution
Authors: Kido R. , Ueda H.
Published: February 2025

In the earth drilling method, which is an example of construction of structural foundations, the ground is excavated using a stabilising solution composed mainly of bentonite, and the trench walls are stabilised by an impermeable mud film formed on the trench walls. Microscopically, the mud film is supposed to be formed when bentonite in the stabilising solution occludes the pores, but this has never been experimentally verified. To elucidate the mechanism of mud film formation, a test apparatus of stabilising solution infiltration that can be applied to X-ray micro-computed tomography was developed, and the soil particle structure before and after infiltration of the stabilising solution is visualised. An image analysis algorithm was developed to investigate spatial and volumetric distribution of bentonite inside the sand. As a result, the formation of a uniformly continuous mud film was successfully visualised in three dimensions. Furthermore, it was found that bentonite occluded many pores in the sand, and that the higher the infiltration pressure, the larger the volume of bentonite that was spatially distributed. Under low infiltration pressure, small volumes of bentonite distribute over a wider area along the infiltration direction.

Published: February 2025

In this work, MXene and Ag nanoparticle (Ag NP)–decorated aligned Ag nanowires (Ag NWs) are applied to achieve surface-enhanced Raman scattering (SERS). MXene/Ag NP–decorated aligned Ag NWs based PDMS (polydimethylsiloxane) (MAAP) substrate is fabricated following the order of oil–water–air interfacial self-assembly of aligned Ag NWs, then surface modification of Ag NPs, and drop-casting of MXene last. The synergistic effect of MXene and Ag NP–decorated Ag NWs confers the MAAP substrate with high sensitivity, universality (limit of detection of 10−10 M for rhodamine 6G and crystal violet, 10−9 M for malachite green), and reproducibility. Based on the existence of PDMS, the MAAP substrate exhibits a good flexibility, and it maintains a high Raman activity after stretching and bending for 100 times. In addition, the surface covering MXene prevents Ag NWs decorated by Ag NPs from oxidation, which made the MAAP substrate still have a relatively high Raman activity. The fabricated MAAP substrate enriches the family members of MXene-based SERS substrates and displays an application value in SERS on irregular surfaces.

Authors: Erazo Daniel Fernando , Niño Vargas Adriana Katerine , Nunez Vallejos Diego Alejandro
Published: February 2025

Objetivo: Hacer un análisis de viabilidad técnica de un biocoagulante derivado de semillas de Moringa oleífera, como una alternativa para reducir el consumo de sales inorgánicas, aprovechando el efecto combinado de coagulantes inorgánicos y biocoagulantes. Metodología: Para llevar a cabo este estudio, se empleó un diseño factorial 4x2 en el cual se disolvió el biocoagulante combinado en diferentes concentraciones de cloruro de sodio (0.25M, 0.5M y, 0.75M) con el objetivo de determinar la eficiencia en la eliminación de turbiedad, color y potencial Z en distintos niveles de combinación de biocoagulante y sulfato de aluminio. Resultados: Los resultados señalaron que el polvo de Moringa (MO), al interactuar con otros compuestos mediante adsorción, puentes y complejos, facilita la coagulación, promoviendo la formación de flocs. Además, se observó que al diluir el polvo en solución salina de 0.75 M se obtiene un biocoagulante que conserva parte de los componentes activos, pese a la degradación parcial de algunas proteínas. En contraste, con una concentración de sal de 0.5 M y una combinación de sulfato de aluminio y Moringa oleífera de 50/50, se lograron remociones de hasta un 98% de turbiedad y color. Conclusión: Se evidenció el alto potencial del coagulante combinado para reducir la turbiedad y el color en el agua con un menor requerimiento de sales inorgánicas. Sin embargo, se observó una limitación en la vida útil del biocoagulante, lo que sugiere la necesidad de investigar métodos para prolongar su conservación.

Feasibility of Polarization Division Multiplexing for Bidirectional Optical Links in 5G Radio over Fiber Cloud Access Networks
Authors: Puerto Leguizamón Gustavo , Suárez Fajardo Carlos Arturo
Published: February 2025

Objective: To investigate the potential of polarization division multiplexing in a 5G radio over fiber cloud access network to enable bidirectional optical links in the front-haul segment.  Methodology: An optically centralized cloud radio access network based on polarization division multiplexing and radio-over-fiber transport is proposed. The exploitation of the polarization domain enables independent optical wavelength channels for the downlink and uplink. The experimental demonstration assesses the feasibility of the radio-over-fiber transport of information in a 5G-cloud radio access network. The demonstration evaluated the Error Vector Magnitude measurements for optical carrier linewidths of 0.1 nm. Data was experimentally measured for QPSK and 64QAM signals onto 3.5 GHz radio frequency across 10 km and 20 km of single mode optical fiber.
Results: The experimental results evaluated the quality of the QPSK and 64QAM signals transported onto a polarization division multiplexing environment for an optically centralized transport in a 5G-cloud radio access network. 64QAM featured an EVM below 6% with a degradation of 2.8% and QPSK presented and EVM below 8% with a degradation of roughly 4.8% with respect to the back-to-back signal across a propagation length of 20 km. Conclusions: The results demonstrated that polarization multiplexing for an optically centralized transport in a 5G-cloud radio access network is feasible. Despite the relatively low optical power received in the uplink, the power penalties of the polarized components did not compromise the power budget so that optical amplification was not included in the measurements. Both QPSK and 64QAM fulfills the requirements of the 3GPP in terms of quality and signal integrity.

Expanded visions: A new anthropology of the moving image
Authors: Lauwrens Jenni
Published: February 2025

In Expanded visions: A new anthropology of the moving image, Arnd Schneider draws on a wide range of time-based media commonly used in contemporary art but not often used in anthropology to propose a new anthropology of the moving image. Schneider takes his cue from Gene Youngblood's influential Expanded cinema (1970), which opened up new debates in experimental film and the then-emerging moving image media. Schneider argues that, owing to current developments in moving image practices, an expanded anthropology of vision is now required. Therefore, this book is situated in what Schneider refers to as a 'third space' (1), which is opened up by new moving image practices currently used in contemporary art and experimental film. The author argues that by thinking with experimental approaches to art and film, visual anthropologists and ethnographers can incorporate innovative techniques to overcome the realist-naturalist paradigm that still tends to dominate anthropological research and representation.

Numerical methods for checking the stability of gyroscopic systems
Authors: Kuzmanović Ivičić Ivana
Published: February 2025

Gyroscopic mechanical systems are modeled by the second-order differential equation\begin{equation*}\displaystyle M \ddot x(t) + G\dot x(t) + K x(t) = 0,\end{equation*} where \(M\in\mathbb{R}^{n\times n}\) is a symmetric and positive definite matrix, $G \in\mathbb{R}^{n\times n}$ is a skew-symmetric ($G^T=-G$) matrix, and $K\in\mathbb{R}^{n\times n}$ is a symmetric matrix, representing the mass, gyroscopic, and stiffness matrices, respectively. The stability of such systems, which is the primary topic of this paper, is determined by the properties of the associated quadratic eigenvalue problem (QEP)\begin{equation*}{\mathcal G}(\lambda)x=(\lambda^2M+\lambda G+K)x=0, \quad x\in\mathbb{C}^{n},\ x\not=0.\end{equation*} In this paper, we provide an overview of various linearizations of the QEP and propose numerical methods for checking the stability of gyroscopic systems based on solving the linearized problem. We present examples that demonstrate how the use of numerical methods provides a significantly larger stability region, which cannot be detected using the considered non-spectral criteria, or verify stability in cases where non-spectral criteria are not applicable, highlighting the advantages of numerical methods.
Citizens in Distress: A Case Study on Public Participation During the Covid‐19 Pandemic in Finland
Authors: Värttö Mikko
Published: February 2025

In emergencies, public participation can perform a positive function by raising public awareness of the potential harms and injustices that may have resulted from emergency measures and policies. In this way, public participation can contribute to democratic crisis management, and also legitimise democratic institutions more broadly. However, emergency conditions can challenge these participatory practices, undermining citizens’ ability to influence crisis management. To investigate this phenomenon, this article studies how ordinary citizens participated in the management of the Covid‐19 pandemic. The article focuses on Finland, a critical case because its response to the pandemic is often considered successful in international comparison. In the analysis, data on various formal and informal forms of public participation are considered and their impact on emergency response is assessed. The findings show that although multiple forms of public participation were in place, the authorities used them selectively and hesitantly. Also, public participation was often diminished to an advisory role or channelled through established civil society actors, such as labour market organisations. Due to this lack of critical voices in public arenas, citizens decided to bypass formal routes of public participation to express their concerns through civic activism in informal channels. These concerns materialised in campaigns, protests, and demonstrations against emergency measures and policies. While much of the existing literature focuses on the negative effects of civic activism, such as spreading misinformation and undermining official measures, this article argues that informal public participation, such as civic activism, can complement formal decision‐making measures during emergencies, thus contributing to more effective and democratic crisis governance.
Community Mobilisation Through Translation: A Sustainable Framework for Participatory Planning
Authors: Tan Xiaohong , Xu Yongjian , Rui Guangye
Published: February 2025

Participatory planning in neighbourhood regeneration faces challenges, including engagement difficulties, consensus-building, implementation complexities, and expectation management. This article investigates participatory planning processes aimed at addressing the aforementioned challenges in Bijiang Village, China. Using the framework of translation, it explores how this approach facilitates community mobilisation and engagement to achieve the United Nations Sustainable Development Goals (SDGs), specifically focusing on fostering sustainable communities. Translation theory comprises four moments: problematisation, interessement, enrolment, and mobilisation. The empirical studies demonstrate that these moments are dynamic and iterative. Initial problem framing, focused on historical landscapes, was unclear at first but became more defined through interest assignment, recruitment, and mobilisation. The interessement phase identifies stakeholders with shared concerns and values, empowering them early in the decision-making process. Enrolment effectively expanded participation by mobilising key stakeholders, such as clan elders and parents, through context-specific social networks and social ecology. This approach ensures that planning outcomes reflect community values and priorities. Mobilisation in Bijiang expanded participation, turned consensus into action, and fostered collective ownership and unity. Workshops, exhibitions, and focus groups translated public issues into defined community planning problems, facilitating the co-construction of solutions. These participatory methods made complex planning terms accessible, fostering deeper community involvement. The cyclical nature of problem framing and consensus-building in Bijiang Village underscores the importance of local socio-cultural context in rural regeneration. Translation theory offers a robust framework for managing complexities in participatory community planning. It demonstrates how continuous negotiation and realignment of interests through translation address immediate concerns and foster long-term engagement, contributing to sustainable development.

This article presents modern approaches to the treatment of comorbid anxiety and depressive disorders in patients with primary painful bladder syndrome. The pharmacotherapy options and various non-pharmacological methods (psychotherapy, cognitive-behavioral therapy, hypnotherapy) for managing these conditions are detailed. It is noted that treatment targeting only the physical component of chronic pelvic pain is often ineffective. To achieve the desired outcome in some patients, it is also necessary to address cognitive, emotional, and behavioral factors associated with pain syndrome.

Published: February 2025

Adequate seedling nutrition is essential for beet production. This study evaluated the effects of applying boron, molybdenum, nitrogen and zinc to seedlings, considering agronomic characteristics and productivity. The experiment was carried out at the São Manuel Experimental Farm of the São Paulo State University, with a randomized block design, seven treatments (fertilizers) and five replicates: T1 - control (without application), T2 - Raiz® (4% N, 5% Mo), T3 - ‘Raiz®+Zintrac®’, T4 - Biotrac® (5.6% N, 2.3% K2O, 1.1% B, 1,1% Zn), T5 - ‘Biotrac®+Zintrac®’, T6 - Zintrac® (1% N, 40% Zn) e T7 - ‘Raiz®+Biotrac®’. Doses of 2.0 mL/L for Biotrac® and 0.5 mL/L for Raiz® and Zintrac® were used. The cultivar used was Betana from Feltrin Sementes®, sown in 200-cell trays. The applications took place 8 days after emergence. Evaluations at transplanting and at the end of the cycle included length, diameter, number of leaves and fresh and dry mass of seedlings and adult plants. Treatment T3 (Raiz® + Zintrac®) showed the highest fresh root mass (120 mg). The combination of Raiz® with Zintrac® and Biotrac® increased the number of leaves (3.6) and fresh root mass (20 mg) compared to the control. The application of Biotrac® alone (T4) resulted in the highest root yields (6.25 and 5.50 t/ha), the largest root diameter (19.68 cm) and the highest fresh leaf mass (125 mg). The Zintrac® (T6) treatment resulted in a higher fresh leaf mass (112.8 mg) than the control. However, the results were below commercial expectations.
Literacy and the Quest for Selfhood in Percival Everett’s James
Authors: Burns Stepto Robert
Published: February 2025

Percival Everett’s novel James won the National Book Award for Fiction and was shortlisted for the Booker Prize in 2024. This masterful retelling of Mark Twain’s The Adventures of Huckleberry Finn, narrated from the perspective of the enslaved Jim/James, offers a key point of engagement with the questions of who and what regulates access to the means of material and literary production—and who, consequently, is entitled to a voice in the American democratic machinery. In his reading of the novel, Professor Emeritus Robert Stepto explores the ways in which Black identity and literacy interact with, and speak back to, the “whiteness” of Huckleberry Finn’s own canonical status.

Use of spectral computed tomography in the diagnosis of posttraumatic mastoiditis complicated by a Bezold’s abscess and a phlegmon of the neck: a clinical case
Authors: Stepanova Elena A. , Egorov Viktor I. , Belyaeva Anna P. , Gerasimenko Mariya V.
Published: February 2025

Bezold’s abscess is a rare intra-temporal complication of mastoiditis; it is a deep cervical abscess with the spread of infection from the mastoid to medial to the attachment of the sternocleidomastoid muscle. There are less than 100 cases of Bezold’s abscess described in the literature. Computed tomography (CT) of the temporal bone and neck has been accepted as a tool for the primary and precise diagnostics. The most common radiological signs include destructive abnormalities of the temporal mastoid (53 to 67% of the cases) and an abscess in the neck soft tissues (60% of the cases). There have been isolated reports on the presence of a substrate in the mastoid without any visible destruction.
We present a rare clinical case of primary posttraumatic mastoiditis complicated by Bezold’s abscess and phlegmon of the neck. Patient S., 39 years old, was admitted with complaints of discharge from the right ear, decreased hearing on the right side, tenderness in the right retroauricular region, erythema and swelling on the lateral neck surface, and increased body temperature to 38.3 °C. A week before hospitalization, he had been hit in his right ear. CT of the temporal bones showed no mastoid destruction. The contrast-enhanced neck CT in the conventional mode was unremarkable for any liquid-containing masses and thickening or lumping. Virtual mono-energetic images 40 keV generated from spectral CT scans were able to identify liquid-containing delimited masses representing the accumulation of pus. The patient underwent right antromastoidectomy, with opening and drainage of the neck phlegmon. In the postoperative period, his condition improved with a decrease in clinical signs and symptoms and serum inflammatory markers. The patient was discharged home on the 10th day to be followed up by an ENT specialist.
This clinical observation of a rare atypical mastoiditis in an adult patient demonstrates the important role of CT in the diagnosis and assessment of the disease zone to determine the surgical strategy. The potential of spectral CT allows to visualize neck abscesses before the planning of a surgical intervention and to confirm the clinically based anticipated diagnosis.

Published: February 2025

In the era of Industry 4.0, the success of the adoption of advanced technologies depends on how they are assimilated and incorporated into current production systems. This work focuses on analyzing the state of technological adoption in Small and Medium Enterprises (SMEs) in the metalworking sector in Argentina, analyzing the ICT products implemented in each of the functional areas of the company that maintain interaction with the people who operate them and identifying the knowledge and capabilities of real users for each functional area. For this purpose, an expanded InTICs®methodology was used to measure the degree of technological maturity of a productive company.

Authors: Souza Jonathan , Zaina Luciana
Published: February 2025

User experience (UX) is a topic widely discussed in the software industry. The elaboration of UX requirements is an activity that practitioners face difficulties during the software specification. On the other hand, user stories (US) are a well-known artifacts to describe software requirements. Frequently, acceptance criteria (AC) complement the US specification by giving more details about the require-ment scope, functionality, and quality requirements of the software. Taking into account US/AC relevance, ACUX (Acceptance Criteria of User eXperience) guide was proposed to support software teams to the writing of UX requirements during the elaboration of AC. In this paper, a case study carried out with software teams from two startups investigated the use of ACUX. The study aims to ob-serve the changes that the guide adoption employed in the teams’ routine concer-ned on UX requirements elaboration. The findings revealed that ACUX im-proved team communication and played the role of a reminder for the developers memory about the relevant aspects of UX to be considered in the requirement specification.
Mitigating Sinkhole Attacks in MANET Routing Protocols using Federated Learning HDBNCNN Algorithm
Authors: Vincent Sherril Sophie Maria
Published: February 2025

In network topology, the sinkhole attacks ensue while a malicious node deceives it’s adjust mode in the routing traffic and it results a predominant interruptions like amplified latency, depletion of energy with conceded data reliability. Moreover a decentralized feature of MANETs are specifically exposed to treats and emphasize the necessity of distinct solutions. In this study, Federated Learning is utilized to improve the security and privacy through empowering nodes to train the model deprived of distribution complex data. Then, every node gathers information about the local routing and contributes towards an inclusive model, which captures behaviour of the entire network when conserving its specific privacy. Further, the Hierarchical Deep Belief Network Convolutional Neural Network (HDBNCNN) algorithm has analysed the accumulated data in detecting the anomalies revealing the sinkhole activity centred on learning routing patterns. Besides, detection, the model can implement mitigation approaches, which includes redirecting traffic from conceded nodes and informing the routing tables to reinforce flexibility from imminent attacks. The proposed study aims to enhance the reliability and efficiency of MANETs in attack situations when minimizing overhead from malicious traffic management. By combining progressive ML methods through decentralized network structure, hence the study expressively provides a secure communication in MANETs and contributes a scalable and effective results through evaluating its performance metrics.

Authors: Raj Rishi , Mukherjee Rajesh , Chakraborty Bidesh
Published: February 2025

Yogasana, often simply referred to as “asana”, is a Sanskrit term that encompasses the physical postures or poses practiced in yoga. Traditionally, there are almost 90 classical Yogasanas, each with its unique benefits and variations. It's very important to identify the postures and benefits of each asana. Classifications of Yogasana can have a significant impact on the practice and promotion of yoga, making it more accessible, educational, and safe for people of all skill levels. In this research work, we have automatically identified different Yogasanas from images using a deep neural network. For our work we have considered 10 very popular categories of Yogasana and built a dataset of volume 800 images. Furthermore, the data augmentation (DA) technique is utilized to increase the volume of data by including slightly modified replicas of existing data. Xception, combined with a self-attention network, has been employed to classify various Yogasanas based on diverse images. The model attains an impressive validation accuracy of 99%, surpassing the performance of all other contemporary state-of-the-art models.

Abstract
Introduction: The distribution of death and risk factors in chronic obstructive pulmonary disease (COPD) patients varies according to disease severity. This study aimed to determine the risk factors of mortality in COPD patients.
Methods: This was a retrospective descriptive study with a total sampling method using inclusion and exclusion criteria. Data collection was performed on patients' medical records throughout 2019. The inclusion criteria for this study sample were patients diagnosed with COPD who died in 2019, aged over 25 years old (adults), both male and female. The exclusion criteria were COPD patients with incomplete medical record data.
Results: The total number of samples obtained and included in this study was 31 COPD patients (n=31). The characteristics of the patients showed a predominance of males over females, with a ratio of 9:1. Seventeen samples (58.0%) out of 31 were patients aged >66 years old. Comorbidities accounted for 96.8% of the study population. The most prevalent comorbidity was infection (77.41%), with pneumonia accounting for 38.7% of all deaths. Eighteen patients (58.1%) reported having two or more comorbidities, whilst 28 patients (90.3%) scored 0-7 on the Modified Sequential Organ Failure Assessment (mSOFA) when admitted to the hospital.
Conclusion: This study found that the group of patients with the mSOFA score of 0-7 with the characteristics of being aged >60 years old, males, and having pneumonia infection had the highest mortality rate among other COPD patients who died.
Repensando la geometría solar y la enseñanza del diseño en los Trópicos: Limitaciones y oportunidades de los métodos actuales
Authors: Sancho-Salas Andrea , Flor Jan-Frederik , Fishel Daniel
Published: February 2025

Los métodos tradicionales de enseñanza en arquitectura presentan limitaciones para lograr un profundo entendimiento de la geometría solar y su impacto en el diseño de iluminación, especialmente en los trópicos. En el contexto del cambio climático, es imperativo avanzar en las metodologías educativas para mejorar la comprensión de los estudiantes sobre el rendimiento solar de los edificios. Aunque los métodos de análisis de iluminación están bien establecidos, los métodos de enseñanza de la geometría solar han recibido poca atención. Este estudio investigó las herramientas y métodos de enseñanza comunes que afectan el aprendizaje de los estudiantes. Realizamos una encuesta para comparar el conocimiento de los estudiantes en geometría solar y diseño de iluminación en dos escuelas de arquitectura en Costa Rica y Malasia (n=153). Nuestros hallazgos muestran que los estudiantes en ambos países tienen un bajo conocimiento autoevaluado de la geometría solar, una preferencia por la combinación de herramientas de aprendizaje manuales y digitales, y un fuerte consenso sobre la importancia del conocimiento de la geometría solar para su desarrollo educativo y profesional, lo que destaca la necesidad de mejorar los métodos y herramientas de enseñanza adaptados a los climas tropicales.
