Neighbourhood markets are essential elements within urban areas, with particular relevance in peripheral areas lacking services and gathering places. These markets, considered as public spaces and social architectures, offer significant potential for urban regeneration and social evolution. This study examines the economic and financial aspects of municipal local market regeneration projects, with a specific focus on a peripheral district of the city of Rome (Italy). Socio-economic investigations are utilized to structure a comprehensive framework for assessing project feasibility, with a particular emphasis on public entities as the primary investors. The returns from these endeavours go beyond mere financial gains, encompassing a broad range of considerations, including environmental and social impacts. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Journal of Rock Mechanics and Geotechnical engineering 2023年第12期15卷 3244-3255页

Defects in cast-in-situ piles have an adverse impact on load transfer at the pile‒soil interface and pile bearing capacity. In recent years, thermal integrity profiling (TIP) has been developed to measure temperature profiles of cast-in-situ piles, enabling the detection of structural defects or anomalies at the early stage of construction. However, using this integrity testing method to evaluate potential defects in cast-in-situ piles requires a comprehensive understanding of the mechanism of hydration heat transfer from piles to surrounding soils. In this study, small-scale model tests were conducted in laboratory to investigate the performance of TIP in detecting pile integrity. Fiber-optic distributed temperature sensing (DTS) technology was used to monitor detailed temperature variations along model piles in sand. Additionally, sensors were installed in sand to measure water content and matric suction. An interpretation method against available DTS-based thermal profiles was proposed to reveal the potential defective regions. It shows that the temperature difference between normal and defective piles is more obvious in wet sand. In addition, there is a critical zone of water migration in sand due to the water absorption behavior of cement and temperature transfer-induced water migration in the early-age concrete setting. These findings could provide important insight into the improvement of the TIP testing method for field applications.

In this paper a comprehensive review and analysis on fast charging methods for Li-Ion batteries is reported and assessment of their impact on battery performance addressed. Existing literature proposed and compared several pulse charging strategies, e.g., Positive Pulse Charging (PPC) and Sinusoidal Ripple Current (SRC), with the standard Constant Current Constant Voltage (CCCV) approach, asserting superior outcomes in term charging time, lifetime, and temperature rising. However, it is crucial to highlight that the Electric Vehicles (EVs) typically charge up to 80% to 90% State of Charge (SoC), leading to irrelevant contribution of the CV phase in terms of SoC but heavily contributing to the full charging time, therefore biasing the comparison. A comparative analysis of PPC, SRC against both Constant Current (CC) and CCCV charging methods based on past literatures data and tests is reported here, aiming at highlighting that PC does not significantly impact charging time as compared to CC charging. However, the advantages of PC, including extended battery lifetime, reduced capacity fade, and efficient charging, making it a promising option for the future e-mobility applications. Our evaluation considers several crucial parameters, namely charging time, temperature rise, lifetime, capacity fade, energy efficiency and charge efficiency. Additionally, we considered the practical implementation of pulsed charging strategies with respect to standard ones, considering the challenges and constraints in an actual battery charger. By addressing the feasibility and limitations, our research aims to provide valuable insights for the potential integration of pulsed charging into commercial EV charging infrastructure. © 2024 IEEE.

Traffic signs are essential informative tools for road users, with their quality regulated by international standards. Among the critical parameters for evaluation is retroreflectivity. With the rise of autonomous vehicles (AVs), new tools like LiDAR sensors and cameras have become crucial for assessing traffic signs. However, the relationship between human perception and the physical properties of these signs remains underexplored. This study compares traffic sign evaluations using retroreflectivity measurements, LiDAR data, and human assessment. Approximately 160 traffic signs were analyzed using standardized retroreflectivity measurements, with additional data collected from two different LiDAR systems mounted on an AV. Volunteers conducted human evaluations assessing visibility, legibility, and contrast with surroundings. The handheld reflectometer provided a wide range of retroreflectivity readings, while LiDAR data showed good contrast between sign faces and surroundings, though results varied between the two systems. Human assessments correlated strongly with overall appearance but showed limited correlation with the other methods. This study highlights the strengths and limitations of each evaluation approach, offering insights for improving traffic sign assessment techniques. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Radar interferometry is an innovative measurement technique capable of remotely measuring vibrations in terms of displacement history. It apparently allows overcoming some major drawbacks of the plodding and time-consuming conventional accelerometric experimental setup for vibration testing. Indeed, radar interferometry does not require any access to the structure;moreover, its use is simpler and faster. Therefore, this technique appears very appealing for ambient vibration testing on structures, and in particular on architectural heritage masonry constructions. However, radar interferometry is still affected by some relevant limitations, that currently outweigh the advantages. One of the most important limitations is that displacements are measured only along the line-of-sight;therefore, it is not possible to determine the whole three-dimensional displacement vector for moving structural points and, consequently, to reconstruct three-dimensional mode shapes of structures, whose knowledge is crucial for characterizing the dynamic behavior of structures and for detecting eventual damages. In this paper, a theoretical and experimental approach for reconstructing both three-dimensional displacement vectors and mode shapes of masonry constructions is proposed. This approach is based on the simultaneous use of two synchronized radar interferometers, and on the application of a theoretical model assuming a specific kinematical constraint, which is generally plausible in the case of masonry constructions. The proposed approach has been validated through in-situ experimental tests on a masonry bell tower. © Published under licence by IOP Publishing Ltd.

Introduction: This study was proposed to explore imparities in public transport use, quality assessment, interchange experience, and their correlation with travel satisfaction. Methods: 3538 respondents completed an online questionnaire across urban districts of Hangzhou, China. The modeling process included: 1) statistical analysis, 2) construction of a LightGBM model with parameters optimized via Optuna framework, and 3) SHAP-based synergy analysis and visualization on travel satisfaction regarding quality perceptions of public transport services, interchange experiences, and daily mobility. Results: Daily travel mode, age, transport info inquiry methods, and ride and interchange experiences were the top factors affecting travel satisfaction. The use and knowledge of the metro varied among generations, with a watershed at age 40, where older individuals exhibited enhanced travel satisfaction through taking the metro on daily trips. Channels for acquiring transport information (smartphone apps, toll-free hotlines, websites, etc.) were negligent in ensuring the consistency of information with actual scenarios. As passengers used inquiry services more frequently, reports of deficiencies in interchange guidance increased substantially, leading to spoiled travel satisfaction. Further, satisfaction improvement of the interchange process failed to mitigate the negative effect of augmented interchange time consumption on travel satisfaction. Respondents who took public transport for more than 15 trips a week reported a significantly higher number of dreadful bus rides, particularly the discomfort brought by the start/stop of electric buses. Conclusions: Simpler access to the metro, more streamlined transport information flow, and smoother interchange procedures could contribute to better travel satisfaction across populations.

This study introduces an integrated approach that merges the design of structure and control to study the deployment strategies for tensegrity structures, particularly in the context of space antennas. First, we establish a nonlinear shape control law for clustered tensegrity structures, the solution turns out to solve a constraint linear algebra equation. Leveraging the symmetric nature of the antenna structure, we designate active actuators for the top and bottom cables of the space antenna while considering the remaining cables as passive. To further reduce the number of actuators required, we employ various clustering strategies for the active actuating cables. Results show that the deployment from the initial state to the predetermined targets is successfully guided by the proposed control law through clustering active cables using different actuation strategies. It is significant to note, however, that the energy cost escalates as more cables are clustered into the deployable antenna structures. In the context of space applications, this scenario emphasizes structure design and control are not independent problems. These insights also offer extensive relevance and can be extrapolated to different deployable tensegrity structures and robotic systems. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Immersive virtual reality(IVR) as an emerging architectural design tool is utilized by many architecture firms to assist in better design decision-making. It allows users to immersively experience the simulated architectural environment prior to real construction. However, compared to conventional computational design tools, IVR faces more challenges in assessing the perception of designed simulations and visualizations. This paper attempts to examine the possibilities for incorporating human biological data and deep learning technology into the process of immersive visualization in architectural design. It aims to objectively understand human perception in an immersive virtual architectural environment, and ultimately assist in design decision-making and human-centered architectural design. The study proposes a novel and multidisciplinary use of techniques derived from psychology, computer science, and architecture disciplines to explore how biological data might be understood architecturally and vice versa. It also provides an opportunity to explore ways of using IVR-based computational design in the new metaverse era. The experiment results illustrate that there is a significant correlation between environmental experience and brain activation. It indicates the integration of EEG and deep learning is helpful to perform as complementary tools for better understanding human perception in immersive virtual architectural environments. © 2023 and published by the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA), Hong Kong.

In this paper, the seismic behaviour assessment of a masonry building aggregate, one of the most widespread house typologies of historical centres, placed in a small burg in South Italy, is discussed through the definition of both capacity and fragility curves. In the first part of the work, the historical centre, where the case study is located, is introduced by describing its historical evolution. Subsequently, the main architectonical and structural features of the selected aggregate are illustrated, according to the instructions of the CARTIS Form, developed within the WP2 of the DPC - ReLUIS Italian research project. After the knowledge phase, in the following step the evaluation of the entire structural aggregate is analysed considering the incapacity to seismically analyse the single structural units without accounting for the dynamic interactions among them under earthquake ground motion. Since the non - linear analyses underline the inadequate behaviour of the aggregate in both seismic directions (longitudinal and transverse), a consolidating intervention, consisting in the application of a seismic coating system, is hypothesized to improve, using an integrated approach, both seismic and energy performances of the basic aggregate. In the last part of the work, a comparison among results in terms of seismic safety index, intended as the ratio between capacity and demand in terms of PGA, and fragility curves, before and after the intervention, is made in order to evaluate the behaviour of the aggregate structural units after the application of the seismic coat on the heading unit. © 2023 COMPDYN Proceedings.

Planning optimal minimum-jerk trajectories for redundant robots

引用

Robotics and Autonomous Systems 2025年 192卷

作者： Lozer, Federico Scalera, Lorenzo Boscariol, Paolo Gasparetto, Alessandro Polytechnic Department of Engineering and Architecture University of Udine Udine33100 Italy Department of Management and Engineering University of Padova Vicenza36100 Italy

In this paper, a minimum-jerk trajectory planning approach for redundant manipulators is presented. The proposed approach leverages not only the optimization of the time intervals between each of the way points of the assigned path, but also the optimal positions of a selected robot joint to reduce the jerk of the robot end-effector. This multi-stage optimization strategy is validated through extensive numerical simulations and experimental tests on a robot with seven degrees of freedom performing a pick-and-place motion. The results of the tests, supported by accelerometer measurements of the vibrations of the robot end-effector, prove the performance of the proposed approach in reducing both the acceleration and the jerk levels of the redundant manipulator in comparison with a state-of-the-art trajectory planning technique. © 2025 The Authors
