semi-analytical solution for static and forced vibration problems of laminated beams through smooth fundamental functions method
در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولInter-Pseudolite Range Augmented GNSS PPP Navigation for Airborne Pseudolite System
Ground-based pseudolite navigation systems have several limitations, such as low vertical accuracy, susceptibility to multipath effects, and near-far signal problems. These limitations could be addressed with an airborne pseudolite system. However, to ensure high user positioning accuracy the aerial signal transmitters have to be accurately positioned. Commonly used methods are based on the “in...
متن کاملThe Lambda Method for the Gnss Compass
Global Navigation Satellite System carrier phase ambiguity resolution is the key to high precision positioning and attitude determination. In this contribution we consider the GNSS compass model. We derive the integer least-squares estimators and discuss the various steps involved in the ambiguity resolution process. This includes the method that has successfully been used in (Park and Teunisse...
متن کاملThe Optimal Regularization Method and its Appli- cation in GNSS Rapid Static Positioning
In rapid static or kinematic positioning, especially with single frequency and shorter period GPS phase observations, the normal matrix may be weak multicollinear since the GPS satellite’s positions and geometries are changing slightly. Therefore the conventional least squares float solution may cause large biases due to the weak multicollinearity and thus make the ambiguity search techniques f...
