A Mixed Methods Research on Anxiety of Arab Students Learning Persian as a Second Language Despite the importance of culture in affecting second/foreign language (L2) anxiety, few, if any, studies have previously dealt with anxiety from Arabic culture’s point of view. So the present study is an attempt to add to our knowledge in the field of L2 education regarding anxiety by studying Arab students learning Persian as a second language in Iran. The participants were 70 Arab students who we...

A New Environmental Perspective to The Concrete, The Most Used Material in Construction as a Significant Pollution Source the use of the concrete in construction around the world is twice as much as the total of all other building materials, including wood, steel, plastic and aluminum. Due to some concrete ingredients such as cement production release many greenhouse emissions to the atmosphere. After fossil fuels and land-use change, it is the third-largest source of anthropogenic emissions of...

Designing the Native Architecture Higher Education Center Of Gilan with Creativity Promotion Approach In today's world, the concern of many architects and critics of architectural education is that the faculties of architecture are not capable to bringing creative and innovative students into the field of employment. About this issue, although researchers and professors of architecture have done significant work, but, these solutions are limited to the problem of architectural education, an...

Longitudinal distance criteria in railway turnouts in different standards and choose the best in practice Different criteria are used for designing and locating railway turnouts in different standards in the world, and one of them is the criteria for selecting the longitudinal distance in the turnouts of the railway stations, In this article, I have tried to compare this criteria in different standards, and finally providing the best criteria based on experience.

Towards Sustainable Urban Development with the Contribution of Ecological Design Principles This study aims at providing a clear and concise framework of sustainable urban development (SUD) to encourage strategically organized ecological efforts in order to develop cities which are sustainable enough to meet their citizens’ needs both in the current and future generation. Today, the ongoing struggles between climate change and urban growth has become more severe and has greatly threatene...

Towards Net-Zero Energy buildings : An effective method of energy control in urban areas A net zero-energy building (ZEB) is a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies. Despite the excitement over the phrase “zero energy,” we lack a common definition, or even a common understanding, of what it means. In this paper, we want to explore the concept of z...

Application of Surrogate Safety Measures for Safe Signal Timing in Urban Intersections Safe Signal timing at urban intersections as bottlenecks of road facilities can be achieved through investigation of traffic conflicts. Traffic conflicts are among safety indices which have the ability to proactively predict safety conditions of a site without any crash occurrence. Attempt is made here to develop models in order to design a safe signal timing for an isolated intersection in Isfahan, Iran, usi...

Automatic Damage Detection in Concrete Gravity Dams Using Vibration Signal Time-Frequency Features and the Support Vector Classifier In dam engineering, damage detection in concrete gravity dams (CGDS) is a practical problem. Dam destruction can have severe financial consequences and may even cause casualties. Therefore, damage detection in advance is absolutely crucial. The main objective of this study is the automatic detection of health or destruction of concrete gravity dams after applying ...

Optimizing energy consumption in dwelling using sustainable design In this study, we analyzed the options in order to achieve a model that is more efficient rather than complex geometries. In general, built buildings, whether residential or another uses of building or with variations in terms of materials, exterior, interior, inadequate placement according to the particular geographic location, Building layout and several environmental and peripheral factors that are not properly used, whether ...
