This article aims to redefine the concept of Thirdspace and make a trilateral relationship between the three concepts of real space, virtual space and the user. To do so, not only the concept of Thirdspace has to be redefined, but also a new understanding of virtual space as a relatively independent space is required. This three-sided relation requires a new understanding of the relationship be...

Background: According to the situation of education in Iran it is clear that over the years, there has been no successful attempt to identify related challenges and problems to development and implementation of virtual training. In this regard, the effect of this type of training influenced by the role of hidden curriculum of education in the country.   Based on this, current study has investig...

The importance of training for operators in industrial contexts is widely highlighted literature. Virtual Reality (VR) technology considered an efficient solution training, since it provides immersive, realistic, and interactive simulations environments where the operator can learn-by-doing, far from risks real field. Its efficacy has been demonstrated by several studies, but a proper assessmen...

The present work is concerned with the design of an innovative ski-boot. In order to optimize ergonomics and biomechanical behavior of the ski-boot it is important to take into account the orientation of the leg with respect to the ground. The SGS system (Stance Geometry System) developed in this work allows the skier to adjust for posture in the frontal plane by rotating the sole of the boot a...

In recent years, the aeronautical industry has established numerical flow simulations as a key element in the aerodynamic design process, complementing wind tunnel and flight testing. Consequently, nowadays numerical simulation is already an important cornerstone for aircraft design. The continuous development of physical models and numerical methods and the availability of increasingly powerfu...

amir kabir dam was built in varian strait, at 23 km north of karaj in 1961. the dam is multipurpose and its maim aims are the spring floods control, supplying potable water for tehran city, producing electricity and providing irrigation water. different pollutants which discharge to the river finally enter to the dam reservoir. determining the pollution loads of the dam sub-catchments can help ...
