AbstractAsbads (Persian windmills) present a multifaceted view of using heritage science. These mills are no longer in use due to advances in technology and the advent of new grinding systems. Windmills show perfect harmony between vernacular architecture and mechanical system. This paper aims to review and analyze the mechanism of one of these windmills in Iran and illustrate how these historical buildings can bridge the gaps between these two science branches for better understanding of cultural heritage. To that purpose, a precise 3D modelling of mechanical components and architectural elements is provided based on architectural survey, photographs and sketches. This study addresses how vernacular architecture, with the specific flexibility, can be considered as one of the most useful tools for human beings. Thus, one of the Iranian windmills in Nehbandan was selected through field studies to be modelled. In this construction, local materials such as wood, adobe and stone are used. Findings reveal that windmills and their architectural flexibility are consistent with mechanical components and address environmental needs.

Between 2013 and 2015, Arcadia University in partnership with the Pontifical Commission for Sacred Archaeology and the University of Catania undertook new excavation campaigns in the Catacombs of St. Lucy at Siracusa. The research focuses on some very problematic parts of Region C of the complex, including Oratory C, the so-called Pagan Shrine and Crypt VI. These areas document most effectively the long life of this Christian hypogeum, which incorporated previous structures and artefacts related to the Greek period and continued to be used until the Middle Ages. During the excavation an array of 3D digital techniques (3D scanning, 3d Modelling, Image-based 3D modelling) was used for the daily recording of the archaeological units, but also to create high-resolution virtual replicas of certain districts of the catacombs. Furthermore, the same techniques were applied to support the study of certain classes of materials, such as frescoes and marble architectural elements that could otherwise only be studied in the dark environment of the catacombs, making the visual analysis of such complex artifacts difficult and sometimes misleading, not to mention that the frequent use of strong sources of light for study can also endanger them. The virtual archaeology research undertaken at the Catacombs of St. Lucy represents the first systematic application of 3D digital technologies to the study of such a special archaeological context in Sicily.

There are many domestic applications where a small amount of liquid needs to be applied to a defined small area under strict conditions. In some cases, the sprayed materials are toxic and expensive, and excessive spray will lead to potential damage to other materials and harm to human beings. A controlled micro atomizer is designed by integrating an electronic and mechanical system with adjustable capability to tune the volume. The geometrical dimension of the atomizer is optimized to deliver a right amount of liquid to a predetermined area. To study the influence of atomizer design and air velocity, the sprays issuing from different atomizers of various dimensions are investigated theoretically and computationally under various external flow conditions. It is found that a controlled atomizer can be developed by optimizing the nozzle design.

Abstract - Classical Indian architectural principles and tradition has been collected and preserved in a vast body of literature collectively known as the Vāstuśāstra. This branch of classical Indian knowledge is a realization of Hindu ideals in terms of architectural edifice, which significantly influence the religious architecture of the Indian cultural sphere which extends to the medieval Island of Java. Even though Indian influences are recognizable in the design of Javanese Hindu candis from the Ancient Mataram era, to what extend the Indian vāstuśāstra was followed is less obvious, for the Javanese candis contain some architectural elements that are not found in vāstuśāstra or Indian temples. By identifying and comparing vāstuśāstra and ancient Indian temples with Javanese candis, it should bring more clarity on which elements are part of the Indian culture continuity and which are part of the local genius. By doing so, the relation between Javanese candi and vāstuśāstra could be reasonably deduced. In this study, a comparative and qualitative method with with historical and textual approach is used. The author focuses on the overall form of the elevation as well as the mass and spatial arrangement. This study would collect and compare the relevant parts of vāstuśāstra as well as Indian examples obtained from literary studies with datas from six samples of Mataram era candis, three from the early period and three from the midclassic period.Comparison by the author shows several results. Firstly, the elevation of Mataram era Hindu candi fits into the basic mould of Indian temples as described in the vāstuśāstra, with seven distinct elements in the vertical direction termed Upapīṭha, Adhiṣṭhāna, Pada, Prastara, Gala, Śikhara, and Stūpi. However, various architectural details of these elements have marked differences from the norms of Indian temples and from what is instructed in the Vāstuśāstra. The distinctive Javanese Kala-Makara for example, does not conform to the Indian Toraṇa-Makara described in Mānasāra. Some Javanese elements has no Indian prototype at all. Secondly, the mass and spatial arrangement of Javanese candis have even more pronounced difference than Indian temples. The typical Javanese arrangement of main temple opposing three secondary temples in a row is not found in India. Conversely, Indian arrangement with an attaching Maṇḍapa in front of the main temple tower is not present in Java at all. In the case of orientation, Javanese candis may be oriented to west or east, while Indian temples overwhelmingly preferred east.The result of this study suggests that the relation between Javanese candi and the vāstuśāstra is a loose and flexible one; vāstuśāstra is used on some aspect such as the basic temple shape but disregarded in the details and ornaments. Javanese candi designers freely adopts and discards various parts of the vāstuśāstra according to prevailing conditions. Those conditions might be due to local materials and taste which form distinctive traits of local genius. Javanese designers never sought to replicate a perfect imitation of Indian temples in Java; rather, Javanese designers shows a creative and selective attitude in responding to foreign influence which yields the innovative and unique design of candi. In the oldest phases, Indian influences can be detected in such a way that candi can be considered an Indian export that has been localized. As time goes, especially since the time of Prambanan, Indian prototype becomes more difficult to discerned until candi becomes a thoroughly local architectural product.Key Words: Javanese candi, Indian temple, Vāstuśāstra, Ancient Mataram

This paper discusses visibility potential of local material products that are used as part of architectural spaces. Knowing the visibility potential of local materials is essential to create visual clarity that supports the ease of spatial orientation and navigation and provides a meaningful visual experience in urban public facilities. This study aims at finding the property quality of objects from local materials that contribute to the visibility potential. Field studies were conducted to identify different types of products from local materials and their characteristics associated with the quality of space experience. The visibility analysis using 3D software program then was carried out by simulating the placement of objects as elements of space in a particular spatial configuration. The result reveals several patterns of possible placement of objects from local materials that have the best potential to enhance visibility. These patterns can add to the alternative vocabulary in architectural design.

Abstract Since 1971, it has been known that the atmospheric free radicals play a pivotal role in maintaining the oxidizing power of the troposphere. The existence of the oxidizing power is an important feature of the troposphere to remove primary air pollutants emitted from human beings as well as those from the biosphere. Nevertheless, serious secondary air-pollution incidents can take place due to fast oxidation of the primary pollutants. Elucidating the atmospheric free-radical chemistry is a demanding task in the field of atmospheric chemistry worldwide, which includes two kinds of work: first, the setup of reliable radical detection systems; second, integrated field studies that enable closure studies on the sources and sinks of targeted radicals such as OH and NO3. In this review, we try to review the Chinese efforts to explore the atmospheric free-radical chemistry in such chemical complex environments and the possible link of this fast gas-phase oxidation with the fast formation of secondary air pollution in the city-cluster areas in China.

One might be forgiven for thinking that the concept of ‘vernacular’ architecture is straightforward. First, it suggests a contemporary approach to building that uses local materials and crafts, as well as the indigenous architecture of tribal peoples, such as piledwellings over tropical waters, mud houses in the desert, or animal-hide teepees on the savannah. These buildings can be distinguished easily from other types of buildings that use industrialised construction techniques and materials, such as concrete, sheet glass, plastics and steel. Second, it might suggest an alternative and more wholesome set of values towards life, the environment and aesthetics, than that represented by the out-of-town retail park or the inner-city office tower. Why bother with the word ‘vernacular’, though, let alone ‘indigenous’ or the more problematic ‘primitive’, when ‘traditional’ works well enough? Nothing could be simpler.

Mosuo dwellings are distinctive vernacular architecture forms that are shaped by the unique matriarchal society of Mosuo in Southwest China. They have undergone dramatic transformations during the 21st century as a result of modernization and tourism. There is a lack of theoretical and empirical studies regarding the impact on the authenticity. This paper aims to fill this gap and develops a theoretical framework—cultural architectural assets—to understand and interpret the transitions of Mosuo dwellings and their authenticity in transitions. Adopting an anthropological methodology approach, this article examines the changes and continuities of Mosuo dwellings during the last thirty years. Fieldwork was conducted in nine Mosuo villages in Yongning Township through a range of qualitative methods, including participatory observations, photographic survey and photo elicitation interviews. The investigation results revealed cultural-architectural elements that are continued in the transitions include the courtyard form, the sacred chamber and the grandmother’s house; cultural-architectural elements that are changing include the flower house and grass house; cultural-architectural elements that are disappearing include the back room (Dupan) and the upper hearth in the grandmother’s house as well as the wooden shingle roof. As a result, the study constructs a conservation approach for sustainable development in three dimensions: living culture, building culture and values and beliefs. This analytical framework can be adapted to be applied to different contexts as a sustainable approach for the conservation and development of vernacular architecture in transitions.

In today's world, sustainability is gaining importance primarily in architecture; it should be possible to build it sustainably in the tropics. An example of this is the vernacular architecture, local materials and an adaptation to the environment, which enable the design of outstanding dwellings, which do not rely on technical tools. Unfortunately there is a great imbalance in Bali, and the local population is still strongly dependent on the building of the vernacular. The tourism industry has created its own high-tech architecture. Apart from a few exceptions, the luxury tourism industry nowadays has to deal with climatic factors instead of adapting them. Now I would like to research in a case study which aspects make the Balinese house so adapted and whether these aspects are still valid for today's claims. Basically, I asked myself these four questions: What are the characteristics of a contemporary tropical house in Bali? What aspects make these houses a tropical house without a negative impact on the Balinese vernacular architecture? What architectural means can help to create a local identity? Which architectural instrument makes it possible to integrate into Balinese urbanity? I would like to try to answer these questions using the case study of two examples and my gained knowledge. Index Terms— sustainability, vernacular, architecture

Qeshm, an island in southern Iran, has two significant elements of sustainable architecture—wind catcher and Latticework (Moshabak). So, it can be defined based on its performance-oriented vernacular architecture which results in the wind renewable energy. However, there are few studies on these sustainable elements. The present study attempted to analyze the performance and structure of these natural ventilation systems in the island. In our research methodology, we tried to use the qualitative approach. Initially, we used citation and library sources for gathering information. Later, we visited the site and the native architecture of the island was studied by analyzing and extracting architectural elements from 48 old buildings which are over 70 years old. Moreover, different types of wind energy and Moshabaks used in the island were thoroughly studied. Meanwhile, the temperature during different periods was compared and the height of the wind catchers and their influence on the rate of wind deflector, functional art, and ecology-oriented architecture of the island were evaluated. The results showed that in terms of function, these so-called sustainable native architectural elements have met the natural ventilation requirement appropriately.
