Significant progress has been made in both 2D and 3D content creation recently. In order to integrate the advantages of both, we present Build-it-here, a novel 3D generation method for open vocabulary furniture creation and placing inside empty rooms. By modulating textual input, we achieve few-shot prompting large language models for layout planning. The output room layout is represented by bounding boxes in the empty house. Upon sampling camera view around bounding-box for rendering, we perform text-guided inpainting on masked 2D images. The inpainted object is then reconstructed in 3D and back projected to the room. Qualitative experiments have demonstrated that our method not only achieved open vocabulary diversity but also ensuring the rationality of placements. The scenes generated through this method is photo-realistic and ready for applications like game industry asset usage. © 2024 IEEE.

This study investigates the experiences of married undergraduate students at a Midwestern religious liberal arts institution, with a focus on health consequences of early marriage and strategic implications for biotechnology firms. The study aims to understand the impact of marriage on student engagement and health, examining how married life, interactions with peers, family, and faculty, and involvement in academic and social activities affect students' well-being. Employing a grounded theory approach, the research analyzes the adjustment to married life among college students and its effects on their academic commitment. The findings reveal that marriage introduces complexities such as increased responsibilities and altered social interactions, which could potentially influence students' mental health and academic performance. These factors are critical for biotechnology firms that are developing health and wellness solutions targeted at the college demographic. The study shows that only a small percentage of undergraduate students are married, indicating unique challenges they face, including balancing academic responsibilities with marital life. The relationship quality among these students emerged as a potential factor influencing their academic success and well-being, an aspect crucial for biotechnology companies focusing on mental health interventions. Data from an online survey at a Midwestern college highlights the correlation between marital status and academic performance, with relationship satisfaction and communication playing a negligible role. These insights are vital for biotechnology firms seeking to develop or tailor mental health and wellness programs for this specific group. Furthermore, the adaptation of married students to college life, their social support systems, and levels of marital satisfaction provide a comprehensive understanding of their unique needs and challenges. This knowledge is instrumental for biotechnology firms in creating tar

This paper proposes a multi-scale control scheme aimed at controlling speed, dwell time, and charging time of electric and automated buses performing the transport service on lines where there are no reserved lanes. The proposed control scheme has two layers characterized by different control objectives, level of detail and time scales. The high-level controller periodically solves a multi-objective optimal control problem formalized to ensure an adequate transport service, while the low-level controller, being based on a more accurate description of the bus dynamics and energy consumption, seeks to follow the high-level control actions while taking into account the effective traffic conditions encountered on the line and the effective dynamic behaviour of the bus. The paper concludes with the application to a case study in order to demonstrate the effectiveness of the proposed control scheme. © 2024 IEEE.

With the rapid advancement of intelligent IoT services, the need for high-quality and efficient wireless communication has become increasingly critical for information exchanges and collaborations among intelligent edge devices such as autonomous mobile robots (AMRs), robots in smart factories, and surveillance cameras, etc., Federated Learning (FL) is a promising distributed learning framework by exploring the computation capability on edge devices while protecting data privacy of users. On the other hand, Over-the-Air (OTA) computation techniques is a new paradigm of integrated computation and communication. OTA based FL (OTA-FL) can enhance spectrum efficiency by leveraging the superposition properties of wireless channels for model aggregations. The implementation of OTA-FL on edge devices can further protect user data privacy for clients, improve the throughput of inter-device communications, and enhance the distributed learning performance. However, despite these advantages, the convergence of OTA-FL systems remain vulnerable to model poisoning attacks, presenting significant challenges. In this study, we address these vulnerabilities by proposing a two-phase detection mechanism that secures OTA-FL system while preserving high spectral efficiency. Our simulation results demonstrate that under varying conditions, our approach can make distributed learning more secure and communication-efficient. © 2025 IEEE.

The European Union's territorial expansion has brought to light the existence of regions characterised by uneven development and asymmetric connections to primary infrastructure networks. In particular, the so-called ‘Inner Areas’ cover around 60% of the Italian territory and the national cohesion strategy (SNAI) targeting them was developed to combat marginalisation and demographic decline, while enhancing resilience, adaptation to climate-change, and risk mitigation. Nevertheless, its primary focus on service and infrastructure marginality overlooks broader socio-spatial indicators, particularly resources’ accessibility and use of different mobility modes, hindering its effectiveness. Within this framework, the paper discusses the potential contributions of the configurational approach to mapping territorial accessibility levels through its application to the Italian case. Specifically, it proposes and tests the use of a configuration-informed composite index for territorial imbalances’ mapping, the ‘S3NAI’. The proposal is rooted in a nationwide Space Syntax Angular Segment Analysis performed on primary-roads elements;whence the Normalised Angular Integration, at global and local metric radii, is employed to assess municipalities’ ease of access, accounting for transport network efficiency and connectivity from a human-centred perspective. This aims to move marginality assessments beyond issues of geographical distance and travel-time to include more clearly the social and economic perspective in them. On this basis, the adoption of the configurational approach in mapping marginalities is proposed to enrich and inform the development of national- and regional-level territorial cohesion strategies. © 14th International Space Syntax Symposium, SSS 2024.

To evaluate multiple choice question tests, optical forms are commonly used for large-scale exams and these forms are read by the OMR (Optical Mark Recognition) scanners. However, OMR scanners often misinterpret marks that have not been fully erased, which can lead to incorrect readings. To overcome that shortcoming and reduce the time and labor lost in the assessment process, we developed a novel system based on the density of each individual’s markings, providing a more personalized and accurate approach. Instead of reading according to a specific optical form template, a dynamic and flexible structure was generated where users can create own templates and obtain the model that reads according to that template. We also optimized certain aspects of the system for efficiency, such as image memory transfer and QR code reading. These optimizations significantly increase the performance of the OMR scanners. One of the key issues addressed is inaccurate reading of OMR scanners when a student doesn’t fully erase their markings or when markings are faint. After the scanning process, the proposed approach uses a K-means clustering algorithm to classify different density markings. This technique identifies each student’s personal marking density, enabling a more accurate interpretation of their responses. According to the experimental results, we performed 97.7% improvement compared to the misread optics scanned by the conventional OMR devices. In tests performed on 265.816 optical forms, we obtained an accuracy rate of 99.98% and a reading time of 0.12 seconds per optical form. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
