Two successive analyses were performed based on data from common residents and college students in the city of Hangzhou, China. First, citizens registered various items constituting desirable values of residential outdoor spaces through a preliminary questionnaire. The result proposed three general attributes (functional, aesthetic and ecological) and ten specific qualities of residential outdoor spaces. An analytic hierarchy process (AHP) was applied to an interview survey in order to clarify the weights among these attributes and qualities. Second, principal factors were extracted from the ten specific qualities with principal component analysis (PCA) for both the common case and the campus case. In addition, the variations of respondents’ groups were classified with cluster analysis (CA) using the results of the PCA. The results of the AHP application found that the public prefers the functional attribute, rather than the aesthetic attribute. The latter is always viewed as the core value of open spaces in the eyes of architects and designers. Fur-thermore, comparisons of ten specific qualities showed that the public prefers the open spaces that can be utilized conveniently and easily for group activities, because such spaces keep an active lifestyle of neighborhood communication, which is also seen to protect human-regarding residential environments. Moreover, different groups of respondents diverge largely in terms of gender, age, behavior and preference.展开更多

Greenways are necessary due to their major role in increase of air quality and positive changes in the climate of the urban environments for keeping the environmental quality of the cities and considerably increasing aesthetic values of these environments. Protection of natural ecological systems, provision of extensive recreational opportunities for people in urban regions and rural districts, provision of economic benefits and protection of cultural values and historical heritage are the advantages of designing and creating greenways inside cities. The present paper which was conducted with descriptive-analytical method tried to explain design dimensions of ecological greenways in three urban physical, environmental and social-economic systems by studying suitable experimental concepts and samples in the world. In this regard, this paper studied five main goals of designing greenways: promotion of local and urban accesses with greenways, aesthetic aspects of urban landscapes, improvement of performance and distribution of activities by creating greenways, increase of efficiency and environmental aspects in the city and revival of social values considering economic sustainability and in this regard design strategies and policies were presented for each one of them based on these goals.展开更多

文摘This paper takes initial steps towards developing a theoretical framework of contemplative neuroaesthetics through sensorimotor dynamics.We first argue that this new area has been largely omitted from the contemporary research agenda in neuroaesthetics and thus remains a domain of untapped potential.We seek to define this domain to foster a clear and focused investigation of the capacity of the arts and architecture to induce phenomenological states of a contemplative kind.By proposing a sensorimotor account of the experience of architecture,we operationalize how being attuned to architecture can lead to contemplative states.In contrasting the externally-induced methods with internally-induced methods for eliciting a contemplative state of mind,we argue that architecture may spontaneously and effortlessly lead to such states as certain built features naturally resonate with our sensorimotor system.We suggest that becoming sensible of the resonance and attunement process between internal and external states is what creates an occasion for an externallyinduced contemplative state.Finally,we review neuroscientific studies of architecture,elaborate on the brain regions involved in such aesthetic contemplative responses,provide architectural examples,and point at the contributions that this new area of inquiry may have in fields such as the evidence-based design movement in architecture.
文摘This study examined public attitudes concerning the value of outdoor spaces which people use daily. Two successive analyses were performed based on data from common residents and college students in the city of Hangzhou, China. First, citizens registered various items constituting desirable values of residential outdoor spaces through a preliminary questionnaire. The result proposed three general attributes (functional, aesthetic and ecological) and ten specific qualities of residential outdoor spaces. An analytic hierarchy process (AHP) was applied to an interview survey in order to clarify the weights among these attributes and qualities.

文摘Bazaars are considered essential components of a society’s economy and significant features in the urban context of cities,which have emerged based on exchanging goods and meeting people’s needs.Since the late Qajar period,amidst the rapid changes resulting from interaction with modernization,the form of Tabriz Grand Bazaar has undergone significant changes.The research aims to explain the contemporary transformations of marketplace form in the leather and shoe sectors.The objectives aim to elucidate the contemporary physical,functional,and sementic changes and propose strategies.The research method is qualitative,with a phenomenological approach.The results indicate that the Bazaar has lost some physical and sementic functions.Despite providing goods,it has failed to meet the public’s demands because of eliminating production workshops by changing the productive function to service-oriented and the size and shape of spaces.The decline of religious activities is also one reason for the diminished sementic dimension.Regarding functional and physical aspects,some proposed solutions include preserving the authenticity of the spaces and utilizing suitable Functions with the dominant architectural style.Regarding sementic characteristics,suggestions include enhancing the sense of identity.
文摘The progressive deindustrialisation of many western cities since the 1980s has led to many industrial zones linked to port activities being abandoned or falling into disuse.Cities such as Barcelona,Naples,Lisbon,Amsterdam,and Hamburg have port industrial complexes of high tangible and intangible heritage value that could totally or partially disappear,resulting in an irreparable loss of their scientific,architectural,social,technological,and historical values.With that in mind,Adaptive Reuse(AR)of the built heritage allows the industrial memory of the ports to be preserved by turning them into new functional centres within the existing urban structure.That occurs in the context of the contemporary challenges of those cities,such as touristification,the circular economy and climate change,while guaranteeing the life cycle of those buildings.This article analyses two case studies—the Nederlandsche Scheepsbouw Maatschappij(NDSM)and the Rotterdamsche Droogdok Maatschappij(RDM)shipyards,both in the Netherlands—in order to contribute to the knowledge of AR of Port Industrial Heritage.They are two examples of good practices in port industrial heritage interventions,where the factors behind their acclaim can be easily highlighted.A multi-scale methodology is therefore used and tailored to the case of port industrial heritage,based on analysing previous studies of the heritage in different spheres and on different scales.A relationship matrix tool is thus defined.It enables a comparative study to be conducted,using key variables and indicators,and considering qualitative and quantitative data.That provides extensive output information for each case study,which is summarised in the most favourable factors for the success of the AR of this port industrial heritage.

文摘The purpose of this study is to address the problem of ancient towns dying out in developing countries,particularly China.Intensifying conflicts between human settlements and the natural environment are described,and guidelines are proposed for the development of waterside ancient towns in China’s southern Shaanxi Province in the interest of conserving cultural and natural heritage.The towns of Qingmuchuan,Fenghuang and Houliu were selected as representative examples due to their strong reputation among tourists.They have the characteristics of traditional southern Shaanxi towns,but each has a completely different layout,space and structure.The comparative findings of this research provide a point of reference for establishing guidelines to preserve the integrity of ancient towns worldwide.In this paper,we compare the geographical conditions with the layout and texture of the streets by Google Earth Pro.And we analyze the details of spaces along the river zones,architectural styles and building decorations in order to research the relationship between the natural environment and the human settlement conditions.We note the unfortunate common trend of commercial development steadily taking over the natural environment,particularly the rivers and unique elements of the old towns.Finally,we summarize the similarities and differences of the spatial forms among these towns and put forward proposals for the further development of ancient towns.This research is important for all regions which stand to lose their national treasures.Consequently,measures should be to taken to curtail hyper development before we lose our historicscenery.
文摘The problem of water pollution is one of the long-term difficulties in the process of rural environmental construction and economic development in China.In order to meet the requirements of the country’s green and sustainable development,many regions actively promote the construction of rural sewage treatment and fill in the shortcomings of the rural habitat environment to accelerate the construction of beautiful and livable villages.Through a lot of literature and case studies,this paper explores the environmental problems that are common in rural sewage treatment in the northern region of China,explores advanced domestic and foreign cases and technologies on this topic,and summarizes the landscape design strategies on this issue.From the perspective of ecological landscape design,the thesis seeks the theoretical and technical support for rural sewage treatment in river valley areas,and establishes a bridge between rural sewage treatment technology and ecological landscape.Finally,combining theory with practice,taking the project of Lushi sewage treatment in Sanmenxia as an example,team completed the landscape design of ecological sewage purification display area in Zhangjiacun.The design focuses on presenting the application of internal sewage treatment technology and external landscape aesthetics.According to the main points of ecological landscape design and the theory of ecological edge effect,the local ecological system is effectively protected,and a rural domestic sewage purification display area with economic benefits is constructed.
文摘Communal spaces provide different facilities for users while they are the primary place for the spread of diseases,especially respiratory.Transmission is possible through human behaviors,the way they communicate with each other and breathe in an environment by airborne pathogenic particles.Experts from various fields have gained valuable experience and achievements regarding how to prevent these diseases by means of environmental factors.Due to the spread of the corona virus in the past years,environmental planners and designers seriously considered the need to review the design and use of spatial components.This study provides a framework for decision making and design of communal spaces based on how environmental components can be effective in preventing the spread of respiratory diseases such as coronavirus and influenza.The research method used in this article is logical reasoning combined with ANP method and focus group discussion.According to the results of this research,indoor air quality plays the most crucial role in preventing the transmission of viruses(contagious respiratory diseases)based on expert groups.
文摘The current work aims to present abundant families of the exact solutions of Mikhailov-Novikov-Wang equation via three different techniques.The adopted methods are generalized Kudryashov method(GKM),exponential rational function method(ERFM),and modified extended tanh-function method(METFM).Some plots of some presented new solutions are represented to exhibit wave characteristics.All results in this work are essential to understand the physical meaning and behavior of the investigated equation that sheds light on the importance of investigating various nonlinear wave phenomena in ocean engineering and physics.This equation provides new insights to understand the relationship between the integrability and water waves’phenomena.
文摘The most important waste stream created during oil and gas production is oilfield-produced water.When discharged without treatment,it poses a significant risk of pollution of marine ecosystems.While adequate treatment before disposal is acceptable,achieving authorized discharge criteria continues to be a problem for the petroleum sector.This research examined the physicochemical characteristics of produced water at various month intervals before and after treatment.Heavy metal and organic component concentrations in water samples were determined using atomic absorption spectroscopy and gas chromatography.The results indicate that produced water from a certain Niger Delta oilfield contains significant amounts of heavy metals and some organic compounds after treatment.The present laws,as well as the measurement of dispersed oil and grease content,have been in place for a long period of time without considerable change,even though most dangerous components in produced water are dissolved.It is recommendable for the prospective field developers/operators to consider the dissolved components of produced water and consider the economic consequences of adopting tertiary produced water polishing technologies.

文摘Various regions are becoming increasingly vulnerable to the increased frequency of floods due to the recent changes in climate and precipitation patterns throughout the world.As a result,specific infrastructures,notably bridges,would experience significant flooding for which they were not intended and would be submerged.The flow field and shear stress distribution around tandem bridge piers under pressurized flow conditions for various bridge deck widths are examined using a series of three-dimensional(3D)simulations.It is indicated that scenarios with a deck width to pier diameter(Ld/p)ratio of 3 experience the highest levels of turbulent disturbance.In addition,maximum velocity and shear stresses occur in cases with Ld/p equal to 6.Results indicate that increasing the number of piers from 1 to 2 and 3 results in the increase of bed shear stress by 24%and 20%respectively.Finally,five machine learning algorithms,including Decision Trees(DT),Feed Forward Neural Networks(FFNN),and three Ensemble models,are implemented to estimate the flow field and the turbulent structure.Results indicated that the highest accuracy for estimation of U,and W,were obtained using AdaBoost ensemble with R2=0.946 and 0.951,respectively.Besides,the Random Forest algorithm outperformed AdaBoost slightly in the estimation of V and turbulent kinetic energy(TKE)with R2=0.894 and 0.951,respectively.
文摘Vernacular buildings are known for their localized passive settings to provide comfortable indoor environment without air conditioning systems.One alternative is the consistent ground temperature over the year that earth-sheltered envelopes take the benefit;however,ensuring annual indoor comfort might be challenging.Thus,this research monitors the indoor thermal indicators of 22 earth-sheltered buildings in Meymand,Iran with a warmdry climate.Furthermore,the observations are used to validate the simulation results through two outdoor and indoor environmental parameters,air temperature and relative humidity during the hottest period of the year.Findings indicated that the main thermal comfort differences among case studies were mainly due to their architectural layouts where the associated variables including length,width,height,orientation,window-to-wall ratio,and shading depth were optimized through a linkage between Ladybug-tools and Genetic Algorithm(GA)concerning adaptive thermal comfort model definition and could enhance the annual thermal comfort by 31%.
文摘Clean-energy technologies have been welcomed due to environmental concerns and high fossil-fuel costs.Today,photovoltaic(PV)cells are among the most well-known technologies that are used today to integrate with buildings.Particularly,these cells have attracted the attention of researchers and designers,combined with the windows and facades of buildings,as solar cells that are in a typical window or facade of a building can reduce the demand for urban electricity by generating clean electricity.Among the four generations that have been industrialized in the development of solar cells,the third generation,including dye-sensitized solar cells(DSSCs)and perovskite,is used more in combination with the facades and windows of buildings.Due to the characteristics of these cells,the study of transparency,colour effect and their impact on energy consumption is considerable.Up to now,case studies have highlighted the features mentioned in the building combination.Therefore,this paper aims to provide constructive information about the practical and functional features as well as the limitations of this technology,which can be used as a reference for researchers and designers.
文摘Iran,located in one of the most earthquake-prone regions of the world,has experienced a very large number of destructive earthquakes that brought about considerable loss of human life and economic consequences.The coun‑try possesses a vast number of monumental and vernacular built heritages that are constantly threatened by earth‑quakes.As vernacular techniques for dwellings comply with the needs,comfort,utility,and functionality of people,it is expected that endemic earthquake-resistant techniques make an essential contribution to Iranian vernacular archi‑tecture.The city of Yazd presents a unique and rich vernacular for earthen construction within Iranian architectural heritage,which has resulted in the recognition of the historic fabric of the city as a World Heritage Site since 2017.Considering the importance of exploring diferent local seismic cultures worldwide,this paper introduces an essential part of Iranian local seismic culture by recognising and classifying the vernacular earthquake-resistant techniques used in the earthen architecture of the city of Yazd.The techniques were collected by surveying the historic fabric,using data available in the literature,and interviewing traditional builders and local conservators.Next,the seismic infuence of each technique was evaluated using examples from the performance of adobe constructions during the 2003 Bam earthquake.

文摘The basic attributes of urban built environment are important factors affecting mental state of older adults.Observation and perception are expressions of built environment from objective and subjective perspectives,and their comprehensive effects on older adults’ mental health have not yet been explored and verified.Combined with the ecological model of active living,the social-ecological model for health and environmental psychology for health,this paper took Dalian as an example and integrated multi-source spatio-temporal data,to compare and examine the internal influence mechanism of built environment on older adults’ mental health from objective and perceptual perspectives through structural equation model.The model was further validated by excluding the samples of residential self-selection.The study showed that the proximity and aggregation degree of basic service facilities,such as supermarkets,restaurants,and barbershops,affected older adults’ mental health through direct and perceived mediating paths,in which the high degree of aggregation had a negative effect on the mental health of older adults through perceived paths of noise,insecurity,and poor environmental sanitation;the density of walking path and the local integration,depth,and connectivity of vehicle path had limited interventions on mentality dimension of older adults;the diversity of leisure,landscape,and exercise facilities in community positively affected older adults’ mental health through the direct and perceived mediating paths;underground parking in community and lifts in high-rise buildings had a more positive impact on older adults’ mental health than ground parking and stairs in multi-story buildings.Overall,compared with objective built environment,perceived built environment had a mediating effect and played a more significant role in the mental health of older adults.
文摘Design of greenways is one of the most important planning tools in the promotion of quality of life of the city residents. Greenways are necessary due to their major role in increase of air quality and positive changes in the climate of the urban environments for keeping the environmental quality of the cities and considerably increasing aesthetic values of these environments. Protection of natural ecological systems, provision of extensive recreational opportunities for people in urban regions and rural districts, provision of economic benefits and protection of cultural values and historical heritage are the advantages of designing and creating greenways inside cities. The present paper which was conducted with descriptive-analytical method tried to explain design dimensions of ecological greenways in three urban physical, environmental and social-economic systems by studying suitable experimental concepts and samples in the world. In this regard, this paper studied five main goals of designing greenways: promotion of local and urban accesses with greenways, aesthetic aspects of urban landscapes, improvement of performance and distribution of activities by creating greenways, increase of efficiency and environmental aspects in the city and revival of social values considering economic sustainability and in this regard design strategies and policies were presented for each one of them based on these goals.
