Launching method is commonly applied for installation of heavy template (jacket) platforms. One of the important phases in design and construction of offshore platforms is launching condition. This will insure the safty of the procedure and will optimize the weight of the related members of the jacket. In this article, effective factors and amount of forces that applied on steel jacket during l...

One of the major challenges in designing intelligent vehicles capable of autonomous travel on highways is reliable obstacle detection. Highways present an unknown and dynamic environment with real-time constraints. In addition, the high speeds of travel force a system to detect objects at long ranges. Because of its necessity for mobile robot platforms and intelligent vehicles, there has been a...
Static laser scanning over a wide angle is demonstrated by ranging to 20 laser beams generated by a novel cylindrical quasi-cavity waveguide, using laser triangulation. Baseline distances and outgoing angles unique to each laser beam are calculated by modelling the triangulation arrangement using a system of linear equations and plotting principal rays. The quasi-cavity waveguide, imaging lens ...
در این پایان نامه، با فرض اینکه v یک *c - مدول هیلبرت تولید شده ی شمارا روی یک $ c^{ast} $,ـ جبر $ a $ است، ثابت خواهیم کرد که دنباله ی $ lbrace f_{i}:iin i brace subseteq v $ یک قاب استاندارد برای $ v $ است اگر و تنها اگر سری $ sum_{iin i} langle x,f_{i} angle langle f_{i},x angle $ برای هر $ xin v $ همگرا (در نرم) باشد و ثابت های $d>0$ و $c $ موجود ب...
In this work, a strategy for the generation of the angle reference for a Velocity Field Controller is presented. For an arbitrary trajectory given in its parametric form, it is possible to create a desired velocity field, that could be modified if obstacles were detected by an artificial vision system. Velocity fields are composed by vectors that can be expressed in polar form, i.e. Vx = |−→V |...
This paper proposes an efficient path planning technique for the autonomous collision-free navigation of wheeled mobile robots with simple hardware based on adaptive neuro-fuzzy inference system (ANFIS). The distance between robot and obstacles is measured using three ultrasonic sensors that are installed left, front, right robot. These distances from form inputs to ANFIS-utility function block...
The development of spray is one of the important factors effecting the combustion of PFI engines. This research was carried out in order to investigate some of the spray characteristics from PFI injector. In this study, the injector flux was investigated by a mass method and equations for it were presented. The results showed that in the pressure interval (2 to 6 bar), the relation of flux with...
