Adding Green to Architectures: Empirical Research Based on Indoor Vertical Greening of the Emotional Promotion on Adolescents

Good architectural space design can bring positive emotional stimulation and relaxation to users, but few studies have investigated the quantitative indicators in architectural space design and their impact on user emotions. This study takes the right-angle sandwich interface system in architecture as an example to guide the next vertical greening simulation experiment by comparing the spatial quantitative differences in connection value, integration degree, and population agglomeration. Eighty adolescent volunteers were recruited into a control (artificial decorative wall) and experimental (green wall) group based on wall type. We compared their physiological and psychological indicators, including blood pressure and blood oxygen, and psychological indicators, including POMS and SIAI-S scales. Then, we made predictive factor judgements on vertical green elements. The quantification of the interior space of the building showed consistency in parameter changes, with the central area being the area of connectivity, integration, and crowd aggregation values. After the experiment, the experimental group showed a significant decrease in diastolic blood pressure, systolic blood pressure, and heart rate (p = 0.00) and a significant decrease in tension, anger, fatigue, depression, and panic (p = 0.00). The quantitative relationship between vertical greening elements and emotional promotion using stepwise linear exploration shows that the “vine” element is a significant predictive factor for diastolic blood pressure, T-A emotion, and SIAI-S values. The results enrich the indoor optimization and creation expansion paths of interface systems for various spatial experiences and further provide guidance for urban indoor green construction plans and green landscape facility planning via the emotional influence of indoor vertical space greening on young people.

Evolving Perspectives: the resurgence of wood in Quebec architecture

Over the past two decades, Quebec has undergone a radical transformation in its approach to using wood in architecture, spurred by trade constraints on wood exports to the United States. This evolution is the outcome of synergistic efforts that have facilitated a transition resulting in significant technological and architectural advancements. Historically, Quebec’s vast forest resources have played a pivotal role in the development of local timber construction, particularly through traditional timber frame techniques. However, the 19th century witnessed a shift towards light-frame construction methods like the Balloon Frame, driven by industrialisation and urbanisation. By the mid-20th century, concrete gained dominance, the fruit of prioritising aesthetics over ideology in architectural design, especially in Montreal, where concrete structures flourished. The 1980s trade dispute with the United States marked a turning point, fostering innovation and a paradigm shift in wood use. Collaboration between industry and academia, exemplified by the Krüger Pavilion and the founding of FP Innovations, has propelled large-scale wood construction forward. Cecobois further supports this trend by facilitating access to technological innovations. This era of change highlights both the potential and limitations of wood in architecture, showcasing its role as a versatile and eco-friendly material that can enhance architectural design while facing technical challenges that sometimes limit its visibility and application.

Energy-efficient design of quaternary logic gates and arithmetic circuits using hybrid CNTFET-RRAM technology

Multi-valued logic (MVL) extends binary logic by providing a framework to represent complex systems with more than two truth values. MVL was introduced to confront the enormous interconnect issue associated with the binary logic in implementing the presnt day complex nanoelectronic architectures. This paper delves into the circuit design, computational aspects, and practical applications of the quaternary logic system, which is a type of MVL with four truth values. The multi-threshold property of carbon nanotube field-effect-transistors (CNTFETs), combined with the ability of resistive random-access memory (RRAM) to store multiple resistance values, has enabled the design of quaternary logic gates and arithmetic circuits. A new CNTFET-based design architecture has been proposed to implement the quaternary logic compatible with the existing technologies. Quaternary logic gates such as inverter, NAND, and NOR, and quaternary arithmetic circuits including decoder, half adder, and multiplier have been designed. The power-delay-product (PDP) of the proposed quaternary inverter, NAND, NOR, half adder, and multiplier is 62.38%, 93.4%, 80.29%, 14.79%, and 20% less than the least PDP of the quaternary designs under consideration. The static power reduction due to the effecciency of the design architecture and high OFF state resistance offered by integrating RRAM into the logic design was explored.The proposed circuits have been subject to various types of parameter variations to validate thir proper functionality in presence of these variations.

Epitaxial Core/Shell Nanocrystals of (Europium-Doped) Zirconia and Hafnia.

A careful design of the nanocrystal architecture can strongly enhance the nanocrystal function. So far, this strategy has faced a synthetic bottleneck in the case of refractory oxides. Here we demonstrate the epitaxial growth of hafnia shells onto zirconia cores and pure zirconia shells onto europium-doped zirconia cores. The core/shell structures are fully crystalline. Upon shelling, the optical properties of the europium dopant are dramatically improved (featuring a more uniform coordination and a longer photoluminescence lifetime), indicating the suppression of nonradiative pathways. These results launch the stable zirconium and hafnium oxide hosts as alternatives for the established NaYF4 systems.

Integrated Wearable System for Monitoring Skeletal Muscle Force of Lower Extremities

Continuous monitoring of lower extremity muscles is necessary, as the muscles support many human daily activities, such as maintaining balance, standing, walking, running, and jumping. However, conventional electromyography and physiological cross-sectional area methods inherently encounter obstacles when acquiring precise and real-time data pertaining to human bodies, with a notable lack of consideration for user comfort. Benefitting from the fast development of various fabric-based sensors, this paper addresses these current issues by designing an integrated smart compression stocking system, which includes compression garments, fabric-embedded capacitive pressure sensors, an edge control unit, a user mobile application, and cloud backend. The pipeline architecture design and component selection are discussed in detail to illustrate a comprehensive user-centered STIMES design. Twelve healthy young individuals were recruited for clinical experiments to perform maximum voluntary isometric ankle plantarflexion contractions. All data were simultaneously collected through the integrated smart compression stocking system and a muscle force measurement system (Humac NORM, software version HUMAC2015). The obtained correlation coefficients above 0.92 indicated high linear relationships between the muscle torque and the proposed system readout. Two-way ANOVA analysis further stressed that different ankle angles (p = 0.055) had more important effects on the results than different subjects (p = 0.290). Hence, the integrated smart compression stocking system can be used to monitor the muscle force of the lower extremities in isometric mode.

XR Experience in Architectural Design Studio Education: A Systematic Literature Review

Pursuing innovative methods in architectural education continually evolves in response to the profession's dynamic and changing demands. Today, Extended Reality (XR) technologies are emerging as powerful tools with the potential to transform design studio education fundamentally. Focusing on "Extended Reality (XR)" rather than individual terms like VR, AR, and MR is due to XR's encompassing nature. Using all realities collectively allows for a comprehensive evaluation of their synergies. Each reality has distinctive capabilities, and their combined use may offer a richer educational experience than focusing on them individually. This study examines the use and impact of XR technologies in architectural design studio education (ADSE), exploring how conventional components can evolve with XR from 2019 to 2024. It highlights XR's influence on design studio education and experiential learning, guiding students, educators, and researchers at the intersection of XR and ADSE. The authors conducted a systematic literature review following the PRISMA (2020) checklist (Page M.J.et al.,2021). Searches in three primary databases resulted in 183 articles. After identifying and removing duplicates, 178 abstracts were reviewed, and full texts were examined. Ultimately, three articles related to “XR Experiences in ADSE" were subjected to detailed analysis. The research found limited studies with the “the impact of the XR in architectural education" keyword. Following the systematic review, three articles remained. These articles were assessed to investigate the use of XR technologies in design studio education. The reviewed articles generally indicated positive outcomes from using XR technologies in one or more components of design studio education.

A New Experience for Integration of Section and Model: A Case Report

Architectural education inherently requires continuity. The transformative power of the world, which people have experienced in the last 5 years with crises such as pandemics and earthquakes, has changed and forced the form, style and tools of this continuity. Architectural design education, which was shaped on the axis of a studio culture, had to cope with the ruptures and transitions of a new phase. This case report aims to convey an experience that brought together the adaptation of face-to-face education of the students after the online education and the section-model practice that the studio tutors have experienced before. Since the study tries to repair the correlations between the continuity, ruptures and transitions of architectural design education, integration of section and model has been re-engaged in the studio. The study group consists of architecture students who switched to online education after the February 2023 earthquakes and started face-to-face education again in the fall semester of 2023/2024. As a result, well-thought models, few experiments on the models and quick transfers to digital programs were revealed as three main tendencies in the studio. In conclusion, the adaptation of the student on the axis of continuity and to reinforce the design productivity, design problem-solving skills and the habit of doing design research tried to provide.

From virtual reality to virtual safaris: new form of participatory design in an architectural design project

ABSTRACT Virtual models have the potential to transform architectural design processes by introducing a novel form of participation of project stakeholders. With the concepts of material participation and digital materiality, this research shows how virtual models in meetings called ‘virtual safaris’ set up a space for participation by providing a tangible architectural demonstration. In virtual safaris, virtual models allow participants to imagine and co-design their experience in the future space instead of trying to interpret architectural plans, resulting in more detailed and concrete feedback. Based on observed virtual safaris and interviews, we categorised the participatory aspects of virtual models and safaris into technical features of the virtual models, experiential features of virtual safaris, and organising and arranging virtual safaris. We consider these categories as intertwined, specifying aspects of material participation. They highlight both the complexities of actual usage of virtual reality in co-design and the additional value of virtual safaris as a participatory setting. We conclude that ways of organising and arranging virtual safaris are central for achieving the transformation potential of virtual reality. We also highlight crucial aspects of meetings utilising virtual reality for practitioners and researchers in construction projects.

Time-modulated planar frequency diverse array for multi-target detection

The frequency diverse array (FDA) is a very interesting technique in wireless communications. Many research papers are introduced in this field. A lot of them is concerned with linear point sources array. In this paper, a design of a time-modulated planar frequency diverse array architecture is proposed for tracking single or multi-target for the first time. The time-modulation array (TMA) and FDA are combined for detecting single and multi-target. The effectiveness of this combined scheme is demonstrated through simulation results that compared with a point source case to show its superior performance. Authors introduce planar FDA array instead of linear FDA array and realize the planar array using cylindrical dielectric resonator antenna array (CDRA). A planar array consists of 8 × 8 CDRA is used to enable the detection of single target/multi-target. The operating frequency of the antenna is set at 10 GHz, aligning with its applications in the FDA radar. The radiation characteristics of the CDRA antenna element are introduced. High maximum gain of 6 dBi is achieved with a remarkably high efficiency. A set of representative results is reported and analyzed to assess the effectiveness of the proposed approach.

Digital Twin concept and architecture for fleets of hydrogen electrolysers

The expected increase in green hydrogen demand in the near future necessitates scaling-up the hydrogen production plants with the goal of reducing the hydrogen production costs. Nevertheless, a quick scale-up limits the time to test new designs, optimize operation schedules and build up knowledge for production parameters. The Digital Twin concept applied on a fleet of electrolysers is proposed as a digitization tool to contribute to this scale-up process by providing a comprehensive view of the entire electrolysers fleet as well as constructing the feedback connection to the electrolysers manufacturing process. Such Fleet Digital Twin approach can improve the efficiency and scalability of green hydrogen production using water electrolysis. This paper presents a concept of a Fleet Digital Twin and discusses its architecture requirements and design. By applying the Digital Twin concept at different levels of the system, fleet knowledge services are enabled by leveraging the availability of fleet-wide data. The proposed architecture design provides a solid foundation for future development and implementation of Fleet Digital Twins in industrial applications.

Structural literacy in architectural studio learning

ABSTRACT Architectural education encompasses a multidisciplinary curriculum including design, theory, history, technology, environmental considerations, urban planning, social aspects, and professional practice. This study aims to investigate the extent to which students can effectively integrate structural concepts into architectural design. This examination takes place within the framework of a third-year architectural design studio course, where students advance their design processes with input from architectural design instructors and experts in structural concepts. To facilitate this endeavour, a simple visual screening form was introduced to aid in the learning process. The study utilises a newly generated survey, namely ‘Structural System Control Form’, which is inspired by the rapid visual screening forms, to assess the students’ comprehension of structural concepts during a 14-week architectural design studio. Employing a descriptive and correlational research approach, the study assesses the effectiveness of this integrated strategy in enhancing the students’ understanding of structural principles. The findings revealed a notable development among students who participated in the integrated approach, highlighting the value of feedback and evaluation from instructors versed in construction. Furthermore, the use of simplified structural models in students’ projects improved their understanding of structural concepts and their ability to incorporate them into their architectural representations.

Architecture Preliminary Design and Trade-Off Optimization of Stratospheric Airship Based on MBSE

System architecture design is crucial for forward design in aerostat system engineering, yet a comprehensive research framework has been lacking. This paper presents a new method for stratospheric airship architecture preliminary design and optimization trade-off, grounded in Model-Based Systems Engineering (MBSE) theory. Firstly, a requirement analysis for a stratospheric airship is conducted using SysML, leading to the analysis and acquisition of the airship’s mission architecture design. Additionally, a multidisciplinary coupling simulation platform is developed with MATLAB, and the architecture preliminary design’s Pareto front is derived using the NSGA-II algorithm. Finally, based on the Pareto optimization set, the TOPSIS algorithm is applied to derive the optimal architecture preliminary design scheme for the airship. The optimization results validate the accuracy of the architecture preliminary design obtained from the requirement analysis, the reliability of the multidisciplinary coupling simulation platform, and the feasibility of the optimization algorithms. This comprehensive study spans the requirement analysis to the optimal architecture scheme, providing theoretical reference and design guidance for the forward design of airship systems engineering.

Continuous blood pressure prediction system using Conv-LSTM network on hybrid latent features of photoplethysmogram (PPG) and electrocardiogram (ECG) signals

Continuous blood pressure (BP) monitoring is essential for managing cardiovascular disease. However, existing devices often require expert handling, highlighting the need for alternative methods to simplify the process. Researchers have developed various methods using physiological signals to address this issue. Yet, many of these methods either fall short in accuracy according to the BHS, AAMI, and IEEE standards for BP measurement devices or suffer from low computational efficiency due to the complexity of their models. To solve this problem, we developed a BP prediction system that merges extracted features of PPG and ECG from two pulses of both signals using convolutional and LSTM layers, followed by incorporating the R-to-R interval durations as additional features for predicting systolic (SBP) and diastolic (DBP) blood pressure. Our findings indicate that the prediction accuracies for SBP and DBP were 5.306 ± 7.248 mmHg with a 0.877 correlation coefficient and 3.296 ± 4.764 mmHg with a 0.918 correlation coefficient, respectively. We found that our proposed model achieved a robust performance on the MIMIC III dataset with a minimum architectural design and high-level accuracy compared to existing methods. Thus, our method not only meets the passing category for BHS, AAMI, and IEEE guidelines but also stands out as the most rapidly accurate deep-learning-based BP measurement device currently available.
