To do this, studied materials are respectively collected from a laterite clay pit in Ndouloumadjie Dembe (Matam, Northern Senegal) and another from a termite mound in Tattaguine (Fatick, Central Senegal). These samples are first subjected to Geotechnical identification tests. Mud bricks are then made with raw or sifted millet involucre improved to 1%, 2%, and 3% at 5 mm sieve samples. These briquettes are subjected to compression tests and thermal evaluations. Lagrange and Newton methods of numeric modelling are used to test the whole mixture points between 1% and 3% millet involucre for a better correlation between mechanical and thermal parameters. The results show that in Matam, as well as in Tattaguine, these muds, raw or improved, are of good thermomechanical quality when they are used in bricks making. And the thermomechanical coupling quality reaches a maximum situated at 2.125% for Ndouloumadjie and 2.05% for Tattaguine. These briquettes’ building quality depends on the mud content used in iron, aluminum, silica and clay. Thus, same natural materials can be used in the establishment of habitats according to their geotechnical, chemical, mechanical and thermal characteristics.展开更多

Traditional methods of design and construction often struggle to adequately predict building longevity, optimize material use, and maintain sustainability throughout a building’s lifecycle. AI technologies, including machine learning, deep learning, and digital twins, present advanced capabilities to overcome these limitations by providing precise predictive analytics, real-time monitoring, and proactive maintenance solutions. This study explores the benefits of integrating AI into building design and construction processes, highlighting key advantages such as improved durability, optimized resource efficiency, and heightened alignment with sustainability goals. As part of this study, the durability aspects are assessed through a strengths, weaknesses, opportunities, and threats analysis. In addition, a sustainability assessment is carried out, taking into account environmental, economic, and social factors, as well as alignment with the United Nations Sustainable Development Goals. Generally, AI-driven predictive models significantly enhance structural durability by forecasting material performance, corrosion risks, and building lifespans with high accuracy. Similarly, AI facilitates sustainable practices by optimizing energy consumption, integrating renewable energy systems efficiently, and significantly reducing carbon footprints. Despite these considerable benefits, implementing AI in the construction industry faces several challenges, including technological complexity, data management concerns, and industry readiness. Nonetheless, future directions emphasize continued development of user-friendly AI platforms, expanded industry collaboration, and rigorous exploration of AI’s transformative potential in sustainable and resilient architecture. Overall, AI is expected to redefine the built environment, delivering buildings that are durable and sustainably integrated within their ecological and social contexts.展开更多

文摘Preserving the spirit of a historical environment does not necessarily mean a repetition of its language generated by nostalgia.The aim of this article is to present the way I was trying to form a real dialogue between a new modern residential building and the existing historic urban district of the city of Tel Aviv,neither by reconstructing the past nor dissociating from it by enforcing a completely new order.A district that already provided a unique interface between Eastern and Western architecture,being a micro-document of the architectural history of Tel Aviv from 1920 to 1930.
文摘Resilience of residential buildings depends on the recovery process that follows the impact of natural hazards,such as tsunamis.In particular,the historical database from tsunamis that occurred in different Countries(Sri Lanka,Thailand,Indonesia,and Japan)have been considered.This study proposes a selection of the best-fitting models to assess the recovery process of tsunamis to derive a framework for resilience at geographical scales.Since the damage depends on the vulnerability of the buildings,several typologies have been considered.In addition,aggregations of different damage sources have been considered to propose comprehensive relationships.The definition of best-fitting recovery functions for different countries has been discussed to implement them in advanced platforms and calculate the resilience to tsunamis.

文摘Artificial intelligence (AI) is transforming the building and construction sector, enabling enhanced design strategies for achieving durable and sustainable structures. Traditional methods of design and construction often struggle to adequately predict building longevity, optimize material use, and maintain sustainability throughout a building’s lifecycle. AI technologies, including machine learning, deep learning, and digital twins, present advanced capabilities to overcome these limitations by providing precise predictive analytics, real-time monitoring, and proactive maintenance solutions. This study explores the benefits of integrating AI into building design and construction processes, highlighting key advantages such as improved durability, optimized resource efficiency, and heightened alignment with sustainability goals. As part of this study, the durability aspects are assessed through a strengths, weaknesses, opportunities, and threats analysis. In addition, a sustainability assessment is carried out, taking into account environmental, economic, and social factors, as well as alignment with the United Nations Sustainable Development Goals. Generally, AI-driven predictive models significantly enhance structural durability by forecasting material performance, corrosion risks, and building lifespans with high accuracy. Similarly, AI facilitates sustainable practices by optimizing energy consumption, integrating renewable energy systems efficiently, and significantly reducing carbon footprints. Despite these considerable benefits, implementing AI in the construction industry faces several challenges, including technological complexity, data management concerns, and industry readiness. Nonetheless, future directions emphasize continued development of user-friendly AI platforms, expanded industry collaboration, and rigorous exploration of AI’s transformative potential in sustainable and resilient architecture. Overall, AI is expected to redefine the built environment, delivering buildings that are durable and sustainably integrated within their ecological and social contexts.
文摘Objectives:This study aimed to establish the concept of overcoming exhaustion,providing a reference basis for nursing management and conducting related nursing research.Methods:Liehr and Smith’s three-phase,nine-step concept-building process was used to create the concept of overcoming exhaustion.The nine steps were as follows:1)write a practice story;2)name the emerging concept;3)select a theoretical lens;4)link concept to literature;5)gather a concept story;6)identify final core qualities;7)formulate concept definition;8)create a concept model;and 9)specify the concept building synthesis.Results:The concept of overcoming exhaustion was identified based on the elements of a practice story,the life experiences of nurses who struggle with the demands of caring for their patients,their families,and themselves.The theory of self-transcendence was then recognized as the theoretical lens from which to ground the concept.The core qualities,despair and moments of calmness,were derived from the literature and confirmed through a concept story.A definition of the concept integrating the core qualities was formed:overcoming exhaustion involves realizing moments of calmness amidst despair.A model was created to demonstrate the relationship between core qualities,despair,and moments of calmness.Conclusions:The concept of overcoming exhaustion was developed and,through the concept-building process,was defined as realizing moments of calmness amidst despair.By identifying the complexities of overcoming exhaustion,this work lays the foundation for a future research program to develop understanding and interventions that support nurse well-being in the context of ongoing personal and professional demands.
