In recent years, unmanned vehicles have intensively been developed to reduce risk on human life for marine applications. Predicting the dynamics behavior of an autonomous underwater vehicle is important during the vehicle’s design phase. In other words to design an AUV, one must clarify its maneuverability and controllability based on a mathematical model. The mathematical model contains variou...

Architectural and artistic remains of the Achaemenid Empire have attracted the attention of scholars for many centuries. Nevertheless, the focus of research has been on locating Achaemenid origins in the architectural forms of other conquered civilizations. More recently, a tendency has emerged that tries to analyze Achaemenid art and history on their own terms. However, little attention has be...

Metal-based composites are currently increased and by growing modern technology, there is more require to the new engineering materials and unique mechanical features. Considering the low density of Aluminum there is more portion for researches about Al-based composites because by increasing its limited strength, the ratio of strength to weight increases the engineering and its productivity. By...
