Stress Analysis of Flight Vehicles under Flight Conditions
A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

متن کاملA Query Language Solution for Fastest Flight Connections
This paper discusses how to extend the applicability of the recursive cascade update command of the Xplain query language. This command guarantees termination because cycle detection is included, which is in favor of end user computing. The execution of this command is based on graph reduction; therefore it can only be applied to acyclic graphs. Because flights constitute cycles between airport...
متن کاملشناسایی و اولویت بندی عوامل موثر بر تاخیرات پروازی و ارائه راهکاری جهت کاهش تاخیر پروازها در ایران determination of root causes of flight delays and introducing a method of mitigation of flight delays in iran
مدتی است که تاخیرات پروازی و مشکلاتی که این مهم برای مسافران پیش می آورد اذهان فعالان صنعت گردشگری بالاخص زیر شاخه این حوزه صنعت حمل و نقل و عامه مردم را به خود معطوف داشته است. بر این اساس هدف این پژوهش بررسی عوامل موثر بر تاخیرهای پروازی و راهکارهای کاهش آنها است. جامعه مورد مطالعه، شامل کلیه مدیران و کارشناسان ارشد فرودگاه های مهرآباد و امام خمینی (ره) در سال 1392 می باشد که به روش نمونه گیر...
Discovering Popular Clicks\' Pattern of Teen Users for Query Recommendation
Search engines are still the most important gates for information search in internet. In this regard, providing the best response in the shortest time possible to the user's request is still desired. Normally, search engines are designed for adults and few policies have been employed considering teen users. Teen users are more biased in clicking the results list than are adult users. This leads...
