The external walls are regarded as an important source for the thermal exchange between the outside and inside of a building. Despite the significance of building walls for energy savings, a large body of research has focused mainly on thermal comfort, environmental impacts, and economic costs of residential buildings. However, few researchers have addressed the thermal performance of common bu...
Abstract Climate has an important effect on operation of the traditional building architecture and its energy consumption in desert area of Iran. Absence of water and unpleasant climate of these regions compelled people to build their houses with some strategies based on effective energy expenditure. Therefore, builders try to use natural climatic strategies for confronting hard situations. Nar...
For the Wayfarer Project, funded by the US Army through TARDEC, we have developed technologies that enable manportable PackBot Wayfarer UGVs to perform autonomous reconnaissance in urban terrain. Each Wayfarer UGV can autonomously follow urban streets and building perimeters while avoiding obstacles and building a map of the terrain. Each UGV is equipped with a 3D stereo vision system, a 360-de...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
This study aimed to evaluate the climatic conditions for the establishment of Borujerd city in the design of buildings and streets of the city with an emphasis on radiant energy, an attempt to reduce problems related to cold climate is that in order to achieve this goal of data synoptic station in the city of Boroujerd a period of 23 years, including temperature, precipitation, relative humidit...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
Vegetation as an essential positive sustainable element of urban spaces has recently gathered increased attention from landscape architects and urban planners. Vegetation growing in urban settings can bring environmental benefits that enhance the health and well-being of citizens through, for example, improved air quality, increased thermal insulation for buildings, reduction of the urban heat-...
in recent years, increasing population, vehicles and industrial growth have caused air pollution that is initiated many environment problems and damaged public health. to check the air quality in different regions, pollution data that are collected in air pollution stations are required. for better and more realistic monitoring of air pollution, the stations must be distributed exactly and even...

Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special struct...
