the first step in evaluating the visual performance and energy efficiency provided by daylight, requires an accurate estimation of the amount of daylight entering a building. the atrium concept allows the exploitation of daylight by bringing natural light into the center of the buildings, thus enhancing even a more distribution of daylight. daylight reception through an atrium is particularly b...

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 ...

With the development of urbanization, more and commercial buildings are built in cities, which is resulting a large amount building energy consumption that threatens ecological environment earth. Lighting occupies proportion consumption, improving quality natural daylight atriums great significance for efficiency as well indoor comfort. This paper proposes method optimizing atriums. Starting fr...

A 72-year-old patient with a history of nonobstructive hypertrophic cardiomyopathy type III and atrial fibrillation of several years’ duration presented to the emergency department with dyspnea at rest (New York Heart Association functional class IV). The patient had been using metoprolol, digoxin, furosemide, and warfarin and had a history of significant variations in the International Normali...

Most cardiologists would probably consider that, during their training, they had received appropriate instruction concerning the mode of development and structure of the atrial septum. This is likely to be founded on the diagrams that exist in most standard textbooks of cardiac embryology. These illustrate the formation of primary and secondary atrial septums as overlapping muscular sheets that...

3D city model reconstruction is one of the main application of airborne laser scanning system. Roof detection is a primary step which needs to find each roof from irregular point clouds with noise points involved. Another problem existed in roof detection is that the detected sequence of roofs will affect the size and shape of detected roofs even though a lot fancy algorithm are applied. In thi...

The rapid and accurate assessment of building damage states using only post-event remote sensing data is critical when performing loss estimation in earthquake emergency response. Damaged roof detection is one of the most efficient methods of assessing building damage. In particular, airborne LiDAR is often used to detect roofs damaged by earthquakes, especially for certain damage types, due to...

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,...

The purpose of this study is to develop an optimum design method for roof shapes satisfying both aesthetic sensibility (beauty) and economic evaluation by using the genetic algorithm (GA). The object is the roof of a gymnasium, and the target roof shape is asymmetrical. The roof shapes were evaluated on the basis of the satisfaction degrees of both economic evaluation and beauty. The economic e...

BACKGROUND Ultrasonography of the hip has gained wide acceptance as a primary method for diagnosis, screening and treatment monitoring of developmental hip dysplasia in infants. The aim of the study was to examine the degree of concordance of two objective classifications of hip morphology and subjective parameters by three investigators with different levels of experience. METHODS In 207 con...
