در این پایان نامه، ابتدا سعی بر آن شده تا رفتار استاتیکی نانوانبرک ها که تحت تاثیر نیروهای الکترواستاتیکی و واندروالسی تحریک می شوند، مورد بررسی قرار گیرد. در ادامه رفتار دینامیکی نانوانبرک ها تحت تاثیر همان نیروهای مشابه مورد مطالعه قرار گرفته است. الکترود های نانو انبرک ها متشکل از نانوتیوب هایی با شرایط مرزی یک سرگیردار در نظر گرفته شده است. در این مطالعه تمامی پارامتر ها در شبیه سازی نانوتی...

In general, Lay and Tow methods are the two most common methods of offshore pipeline installation. In the shallow waters, considering the restrictions of Lay barge, Tow method is usually more appropriate. In this method, pipestring is fabricated on-shore and then it is launched into water. Then, according to environmental conditions and restrictions, the pipeline is towed to the installation s...

The terms pull and lean production have become cornerstones of modern manufacturing practice. But, although they are widely used, they are less widely understood. In this paper, we argue that while the academic literature has steadily revealed the richness of the pull/lean concepts, the practitioner literature has progressively simplified these terms to the point where serious misunderstandings...

The static response of an electrostatic micro-catilever beam has been obtained by using Galerkin’s method. To make the system bi-stable, a controller has been added and the static response profile is presented using a multi-mode model for the beam. The number of mode shapes leading to convergence has been studied. The softening effect of adding more mode shapes has been investigated along with ...
