An Advanced 3D Ray Launching Method for Wireless Propagation Prediction
For radio propagation prediction, recent simulations involving ray tracing offer unprecedented accuracy [1], [11], [13], [14]. These techniques surpass statistical channel models and provide a bounty of additional information including RNIS delay spread, angle of arrival·, and overall wide band channel impulse response. In particular,· three dimensional ray tracing produces an accurate, determi...
متن کاملRetrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...
متن کاملAn Improved 3D Ray Launching Method for Wireless Propagation Prediction
3D ray tracing produces accurate, deterministic channel models for wireless system design. Increasing a ray tracing algorithm's ability to identify correct propagation paths reduces the kinematic errors of a simulation. This paper presents a new 3D ray tracing technique that reduces kinematic errors associated with ray launching algorithms. This work is sponsored by the NSF Presidential Faculty...
متن کاملFree fall and cellular automata
Three reasonable hypotheses—homogeneity in time and space, bounded velocity of propagation of information, and bounded density of information—lead to the thesis that physical phenomena can be described and simulated with cellular automata. This implication has in fact been formalized into a theorem both in the classical [6] and the quantum case [1], albeit in flat space. Further evaluating this...
متن کاملبررسی پدیده برخورد با سرعت بالا با استفاده از روش بدون المان (mesh free method)
در این تحقیق ابتدا با توجه به ویژگی های پدیده ی برخورد با سرعت بالا که عبارتند از تغییر شکل های بزرگ که منجر به یک مسئله ی غیر خطی هندسی و مادی میشود ، سطوح مادی در حال حرکت و سطوح آزاد ، مرزهای تغییر شکل پذیر و سیستم گسسته بر پایه ی قوانین محیط پیوسته، روشsph از میان روش های عددی انتخاب گردیده، سپس نحوه ی تخمین زدن متغیر میدان در این روش، روند فرمول نویسی sph و همچنین جایگاه این روش در میان رو...
