analytically and numerically that multipole sources are divided into two groups according to this principle: in the first group, the sound pressure field and the horizontal projections of the vibration velocity vectors satisfy the reciprocity principle, while the vertical projections of these vectors do...
however, it has not been used to analyze aeromaneuvers, with a focus on aerocapture, which is useful for future interplanetary flights. For example, the PI could be applied to quantify the contribution of the aerodynamic forces during a final approach in planets like Venus, Mars, and Jupiter,...

(e.g., the reference frame of a patient, laboratory or externally applied magnetic field). Two perpendicular unit vectors p1221and p2222indicate the transverse directions perpendicular to the unit vector c. The three unit vectors c, p1 and p2 can be combined as one way of representing the ...
This resulted in spectra in the 18–180 ppm range contained in vectors of 1348 variables. As in the previous section for 1H LF-NMR, the 13C LF-NMR spectra were TSN scaled and the information entropies, HS and HR, were calculated. They are shown in Table S2 (supplementary material). ...
is to turn the unprocessed input signal into a representation with minimal variables, which contains the most discriminating information and which can adequately reduce the input’s dimensionality and eliminate redundant or irrelevant information, in order to produce the series of feature vectors. With...
One bullet will have direction î and the other will have direction - î since they are moving in the same horizontal plane toward each other. As in the last problem, we first draw a sketch. Let's start with the conservation of momentum. The velocity right after the collision is ...

This contribution, which is due to changes in the surface normal vectors with changes in the structural unknowns at fixed flow solution, was found to be very small. The matrix block requires the dependence of the integrated loads on the fluid unknowns, = ∂ /∂ , which is evaluated by...
