Το κεφάλαιο αυτό πραγματεύεται του βασικούς ορισμούς των σημάτων και ταξινομεί τα σήματα. Επίσης αναφέρονται οι βασικές ιδιότητες που παρουσιάζουν τα σήματα και οι μετατροπές σήματος ως προς το χρόνο.
Here, we consider the problem of how body waves (P and S) propagate through a medium in which the elastic parameters vary with spatial location. The two terms containing ∇λ and ∇μ mean that P and S motions do not decouple in heterogeneous media.
16 Μαΐ 2019 · I need to calculate $P(T_2=T_{-3}), P(T_1<T_4<T_{-1})$ and $P(T_3<2)-P(T_{-3}<2)$. I'm not sure if I understand these correctly. I assume the first and the last one are $0$?
15 Αυγ 2017 · We construct all irreducible real (complex) k-potent matrices in an irreducible sign (ray) k-potent sign (ray) pattern class. For a given reducible sign (ray) pattern that is sign (ray) k-potent for some positive integer k, we determine necessary conditions for that pattern to allow k-potence.
Graphics Lecture 1: Slide 2 Ray tracing with secondary rays • Ray tracing using just primary rays produces images similar to normal polygon rendering techniques • Recursive ray tracing, with secondary rays produces more realistic images by adding – shadows – reflections – transparency Graphics Lecture 1: Slide 3 Ray tracing to find ...
The power density w at distance d is w P d = T 4π2 where PT is the transmit power. The received power is w A d = PT 4π2 with A the `antenna aperture' or the effective receiving surface area.
