characteristics of efficient roof shape is a part of configuration of efficient architecture which seems to be an ideal in contemporary architecture especially in contemporary architecture of developing countries such as iran. this study is to investigate two roof shapes in view of air flow and indoor-temperature to find efficient roofs shapes for residential buildings in tehran. computational ...

as a covering method of buildings` roof, domed roofs have mostly been applied in iranian vernacular architecture and also in the middle east region according to adobe material abundance comparing with timber. furthermore, dome remains in the first place in architectural designs due to large area coverage and favorable thermal performance; so that it has been widely utilized in mosques, shrines,...

In hot arid regions, cooling buildings by passive techniques is very important regarding energy saving and the need to keep clean the environment. In such areas, domed and vaulted roofs are widely used for centuries, such as in the Middle East region and central part of Iran. In this article analysis is made to explore east–west direction of wind flow around north–south vaulted roofs and flat r...

For centuries, dome roofs were used in traditional houses in hot regions such as the Middle East and Mediterranean basin due to its thermal advantages, structural benefits and availability of construction materials. This article presents the computational modelling of the windand buoyancy-induced ventilation in a geodesic dome building in a hot climate. The airflow and temperature distributions...

A domination graph of a digraph D, domeD), is created using the vertex set of D, V(D). There is an edge uv in domeD) whenever (u, z) or (v, z) is in the arc set of D, A(D), for every other vertex z E V(D). For only some digraphs D has the structure of domeD) been characterized. Examples of this are tournaments and regular digraphs. The authors have characterizations for the structure of digraph...

The evolution of ecclesiastical architecture during the Early Byzantine period was marked by a major development in construction technology: the gradual transition from the building system of the “timber-roof basilica” to the one of the vaulted church. The early stages of this development seem to date back to the period between the late 5th and the 7th century AD and some of its earliest manife...

The survey of the wooden domed structures surmounting St. Mark's Basilica in Venice is part of a project of documentation, analysis and representation that the E-Lab laboratory of the Politecnico of Milan has been involved in for several years in conjunction with the Procuratoria di Venezia. Three-dimensional modelling and representation through laser scanner acquisition is the method that best...

BACKGROUND The Oxford Unicompartmental Knee Replacement (OUKR) uses a mobile bearing to minimise wear. Bearing dislocation is a problem in the lateral compartment as the ligaments are loose in flexion. A domed tibial component has been introduced to minimise the risk of dislocation, yet they still occur, particularly medially. The aim of this mechanical study was to compare the domed and flat t...

One of the essential needs humans that is influenced by architectural geometry visibility in indoor areas. Prayer hall dominates mosque typology and morphology. The spatial–volumetric shapes interior prayer halls affect worshipers’ visual comfort spirituality. In this study, a new integrative framework developed to quantitatively describe various typo-morphologies affecting worshipers, includin...
