conduct and orientation of states in their foreign policy are affected by geopolitical constant and variable factors. the authors of the present paper try to study the impact of variable factors on determining the islamic republic of iran’s foreign policy in the 1979-2005 period, on the basis of holsti’s trilogy on foreign policy (orientations, national roles and goals). exploiting the concept ...

In order to effectively navigate any environment, a robotic vehicle needs to understand the terrain and obstacles native to that environment. Knowledge of its own location and orientation, and knowledge of the region of operation, can greatly improve the robot’s performance. To this end, we have developed a mobile system for the fast digitization of large-scale environments to develop the a pri...

Transformations of the coordinate systems in which reference vectors initial navigation information - flow sunlight and Earth's magnetic field are set into system sun-synchronous orbit remote sensing satellite by matrix analytical methods considered. The influence accuracy calculating direction cosines orientation matrices on determining its angles scanning is estimated. estimation sensor error...

objectives: the aim of this study is to evaluate the effects of olfaction, audition and tactile senses in mobility and orientation of blinds. methods: the statistical sample of this research included 100 blind persons aged between 16 and 75 years (61 males and 39 females) with different level of education (16 persons lower than the diploma, 26 persons diploma, 46 persons bachelor, 12 person ma)...

Fracture orientation is a prominent factor in determining the reservoir fluid flow direction in a formation because fractures are the major paths through which fluid flow occurs. Hence, a true modeling of orientation leads to a reliable prediction of fluid flow. Traditionally, various distributions are used for orientation modeling in fracture networks. Although they offer a fairly suitable est...

This paper addresses the problem of identifying the property of the singularity loci of a class of 3/6‐ Gough‐Stewart manipulators for general orientations in which the moving platform is an equilateral triangle and the base is a semiregular hexagon. After constructing the Jacobian matrix of this class of 3/6‐Gough‐Stewart manipulators according to the screw theory, a...

Precise registering and transferring of the selected path of insertion and withdrawal of removable, partial dentures is a critical step in designing and fabricating their framework and determining the retention, stability, and support of the completed prosthesis. Many authors have addressed this issue in their studies. In this study we present a new technique for registering and reproducing par...
