چکیده
An online estimation algorithm of landing footprints based on the drag acceleration-energy profile is proposed for an entry hypersonic vehicle. Firstly, Evolved Acceleration Guidance Logic Entry (EAGLE), profiles are designed. To track obtained by interpolation, a acceleration tracking law Secondly, constraint model no-fly zone, flying around strategies different conditions, and reachable area designed zones. Additionally, interpolating minimum maximum profiles, terminal heading angle to realize accurate calculation downrange ranges adjusting sign bank angle. In this way, distribution more reasonable, boundary accurate. The simulation results under typical conditions indicate that method can calculate situations rapidly with good adaptability.

The IUFP Algorithm for Generating Simulation Heart
In all systems simulation, random variates are considered as a main factor and based of simulation heart. Actually, randomization is inducted by random variates in the simulation. Due to the importance of such a problem, a new method for generation of random variates from continuous distributions is presented in this paper. The proposed algorithm, called uniform fractional part (UFP) is simpler...

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملMaturation of the mammalian dorsal root entry zone--from entry to no entry.
Interfaces between glial cell precursors of the PNS and CNS are established early in development and form the sites where sensory axons enter and motor axons exit the developing CNS. The molecular and cellular interactions that lead to the formation of these glial interfaces are only now becoming apparent. New in-vitro techniques are providing clues as to how the maturation of PNS-CNS glial int...
متن کاملProbability Generating Functions for Sattolo’s Algorithm
In 1986 S. Sattolo introduced a simple algorithm for uniform random generation of cyclic permutations on a fixed number of symbols. Recently, H. Prodinger analysed two important random variables associated with the algorithm, and found their mean and variance. H. Mahmoud extended Prodinger’s analysis by finding limit laws for the same two random variables.The present article, starting from the ...
