Driving quality is a concept that includes factors affecting the quality of a vehicle trip. Pavement damages, including roughness, has negative effects on travel comfort and driving quality. The vibration created in the car is one of the most important negative effects. In general, the main reasons for this type of vibration are: The mechanical structure of the vehicle and the surface roughness of the road. In short trips, the quality of driving is affected by safety and driving comfort indicators. While, in long-term trips, the threat to human health is also raised due to long-term vibration on the body. Therefore, it can be concluded that the evaluation of the driving quality and especially the impact of road surface roughness, which is responsible for the phenomenon of vibration, is a vital issue for pavement engineers. As the most common method of assessing road surface roughness, the IRI index is considered an essential element in the framework of this research due to its intrinsic relationship with the vehicle's reaction. This study seeks to reconsider the IRI index according to the vibration created in the car during a trip. For this purpose, first, some pavement segments with certain roughness were defined. Then, with the help of ProVAL software, IRI values were calculated for them. After that, in the main part of the research, the defined pavement segments were made in the ADAMS software, and the vibration results were outputted when a passenger car passed over them. The results of the review and comparison of vibration data and IRI values showed that the IRI method contains an important problem: not fully covering the concept of passenger travel comfort and driving quality. Considering that the IRI index is an important and common factor in the decisions of pavement management systems around the world, this research confirms that this index needs important modifications to effectively include the concept of driving quality in roads' maintenance and repair

Urban planning and changes in the physical-chemical conditions of space resulting from it in the built area affect the energy efficiency and thermal performance of buildings, as guided by energy performance guidelines. The absence of computational simulations that integrate the urban and building scales generates uncertainties in the data. Recent studies highlight differences in results when considering urban configurations. In this work, a methodology was developed for these integrated computational simulations, ensuring precise results regarding potential impact. Softwares Urban Weather Generator (UWG), Climate Change World Weather Generator (CCWWG) and ENVI-met program was used to simulate local and global climate changes, and for use as input in EnergyPlus to simulate thermal performance of a social housing. The results reveal a significant impact of the urban heat islands and global warming on the exterior thermal comfort and building performance, reducing habitability and requiring air conditioning almost all year round, in the future climates. © 2024, The Authors.

In order to maintain, manage, and budget for pavement infrastructure, road pavement condition assessment is necessary. Several pavement characteristics are measured to assess its condition, including pavement strength, roughness, and surface distresses. It is important to categorize studies at deeper levels due to the rapid growth of articles published in this field. The objective of this paper is to provide an overview of machine learning-based pavement evaluation studies and their contributions to the area. In order to facilitate the exploration of the studies employing similar methodologies, the studies are organized based on their goals. Therefore, studies are classified based on the two main categories of goals employed in them, namely: 1. Studies with aim of pavement condition prediction and 2. Studies with the aim of pavement distress detection/classification. It is observed that research of category 1 has grown very well during the past years. Also, category 2 includes studies that mostly focus on crack detection and it can be felt that there is a need for expanding the focus of studies on other types of distresses. © 2023 IEEE.

Measuring urban spatial adaptability to environmental stresses has recently been a popular topic in urban planning towards resilient cities. Urban Resilience has emerged over the past few decades across multiple dimensions from economics, society, environment, physics, and urban planning. Recently, many scholars in the planning have further investigated urban spatial Resilience to natural disasters and have stated that adaptive capacity is the critical factor to achieve Resilience. In Vietnam, the central provinces currently suffer from extreme climate events that cause heavy damage, such as droughts and floods. Ninh Thuan province, located in the South-Central Coast, at coordinates 11°18′14″ to 12°09′15″ Northern latitude, 108°09′08″ to 109°14′25″ Eastern longitude, is the typical place. The case study focuses on the capital city Phan Rang-Thap Cham City’s context—one of the most developed and vulnerable communities in the province of Ninh Thuan—to build an assessment framework of urban spatial adaptability to drought-flood coexistence (DFC). The framework consists of rows of urban spatial components and columns of adaptive indicators and variables to D.F.C. Urban spatial adaptability of Phan Rang-Thap Cham is measured by two methods. The first one is a qualitative analysis of urban spatial components, such as spatial networks and their land covers, based on adaptive variables to D.F.C. The second one is a quantitative analysis of the examined urban spaces interacting with the Remote Sensing (R.S.) index such as Normalized Different Vegetation Index (NDVI) and Land Surface Temperature (LST). Both of the two methods were carried out thanks to the utilities of R.S. and Geographic Information System (G.I.S.). The content of the study is reflected in four parts: (i) Overview of the concepts of urban spatial Resilience and adaptability, (ii) Study methodology and steps, (iii) Assessment framework of urban spatial adaptability to D.F.C., (iv) Conclusions. © 2023, The Aut

This paper presents the power electronics converters of an electric vehicle charging station that works as a DC microgrid with an AC grid interface. The interface converter is an interleaved bidirectional DC-AC converter that enables the V2G (vehicle-to-grid) application. Inside the microgrid, there are converters for managing power from the DC bus to the electrical vehicles (wireless charging type) and stationary battery banks – all bidirectional, too. To constitute the sustainable characteristic of the solution, a solar photovoltaic system is attached to the DC bus through a power electronics converter. The control methodology and experimental results from the proposed system with focus on the converters characteristics are presented. This manuscript highlights a noteworthy reduction in the total harmonic distortion for the injected grid current as well as enhanced stability during battery charging and discharging in both wired and wireless modes.

Incorporating sustainability into Concrete-Filled Steel Tubular (CFST) columns' optimization can enhance efficiency and sustainability in construction. Discrepancies in international standards for ultimate load capacity computation in compact CFST columns under eccentric loading, particularly with lightweight high-strength concrete, pose challenges. This research compile a dataset of compact CFST columns, evaluating design codes (AISC 360-16, Eurocode 4) against experimental results. Besides, a comprehensive finite-element model predicts compact CFST column performance, investigating axial force-moment (P-M) interaction behavior with respect to the material strength ratio (fy/fc′). In the second phase of the study, an ANN model, incorporating input parameters, estimates axial load capacity, facilitating multi-objective optimization for optimal CFST column geometry. The results confirmed that Eurocode 4 outperforms AISC 360-16 in experimental axial capacity predictions (Nuc/Nuc,theoretical) where, the mean and standard deviation for Eurocode 4 were estimated at 1.07 and 0.22, respectively, compared to 1.21 and 0.29 for AISC 360-16. Besides, statistical metrics confirm the precision of the ANN model, particularly with high-strength concrete, promising efficiency in future computational intelligence-based structural design platforms. © 2024 The Authors

The scope of this study is to understand the feasibility of materials from Mato Grosso do Sul, Brazil, for use in the Superpave method of designing asphalt mixes, as well as to analyze the mechanical and volumetric properties of the resulting mixes. The method of asphalt preparation most used today in Brazil is the Marshall dosage. However, given the current global context of asphalt design and the improvements observed in the industry in recent decades, there is a clear need to adopt and improve better pavement system designs in Brazil. With this study, it is possible to better understand and test new paving techniques that can change the current scenario seen in Brazil. It is clear, when analyzing the major problems that arise in the pavement of Brazilian roads, that cracks, permanent deformation, and a low fatigue life are common occurrences in the region. Through this research, the asphalt mix project carried out in the laboratory was tested both in its volumetric properties and in its mechanical properties. The volumetric properties analyzed fully complied with Superpave's international standards for asphalt mixtures, and the mechanical properties were congruent with studies that measure similar properties. The main equipment used for the mechanical properties tests was a universal hydraulic testing machine with a capacity of 30 kN of force. The main tests included resilience modulus, fatigue life, permanent deformation (flow number), and dynamic modulus test. With this, the properties of the laboratory molded asphalt mix project can be analyzed and compared with more traditional methods seen in Brazil, as well as can be used as a future reference for comparison with new asphalt mixes made with similar processes in Brazil. In this study, the laboratory-molded asphalt mix was based on the design of 3-30 million ESALs with a design of 100 turns in a Galileo electromechanical rotating machine, reaching 96% of its maximum theoretical density, with 6% of binder, 15.

In this study, we developed and characterized the thermal and physicochemical properties of a novel Biosourced Composite Phase Change Material (BCPCM) incorporating RT28 HC for energy storage and improving the energy efficiency of buildings. The physicochemical compatibility between RT28 HC and the selected matrix was verified by FTIR, XRD techniques, and observed with SEM. The DSC results indicated that the BCPCM including 50 wt% RT28 HC, has a melting temperature and latent heat property of 31.5°C and 155 J/g, respectively. The TG measurements confirmed the thermal reliability of the BCPCM for building applications. Thermal performance tests using a room revealed that integrating BCPCM plates reduced the internal temperature by 7°C. The thermal conductivity of the RT28 HC incorporated into the BCPCM was improved by 305% by adding 10 wt% of graphite. © 2024, The Authors. All rights reserved.

Air pollution is a significant global problem that affects climate, human, and ecosystem health. Traffic emissions are a major source of atmospheric pollution in large cities. The aim of this research was to support air quality analysis by spatially modelling traffic-induced air pollution dispersion in urban areas at the street level. The dispersion model called the Graz Lagrangian model (GRAL model) was adapted to determine the NOx concentration level based on traffic, meteorology, buildings, and street configuration data in one of Tehran’s high traffic routes. In this case, meteorological parameters such as wind speed and direction were considered significant factors. Later, using local and general auto-correlation analyses, temporal and spatial variations in the concentration of NOx were measured at different altitudes. The results showed that the average output concentration of NOx pollutants at different altitudes ranges from 64.5 to 426.6 ppb. The resulting Moran index equals to 0.7–0.9 which indicates a high level of positive spatial auto-correlation. The analysis of the local Moran index represents the overcame pollution clusters with high levels of concentration at low to medium heights and the rise in clusters with low pollution at higher heights, while there is no clear clustering in the middle sections. In addition, the study of pollutant concentration variations over time has shown that pollution peaks occur at 07:00–08:00 and 21:00–22:00. © 2022 The Author(s).
