node,in astronomy, point at which theorbitof a body crosses a reference plane. One reference plane that is often used is the plane of the earth's orbit around the sun (ecliptic). Since the moon's orbit has aninclinationof 5°9′ to the plane of the ecliptic, there are two nodes in...
In subject area: Physics and Astronomy Digital Signal Processing (DSP) is the manipulation of real-world signals within a digital computer, using mathematical techniques to enhance, change, or display the data in a specific way. It involves converting analog signals (such as audio or video) into...
The closest equivalent in speech is quasiperiodic, meaning that F0 changes over time and has a small amount of noise. A typical example is a vowel, with the fundamental and many harmonics. We can look at and measure the time waveform, but if we want to know the distribution of energy ...
On Oct. 9, 1973, first-responder switchboards were overwhelmed by nearly 700 calls to report UFO sightings. These included blinking lights near the ground, a UFO spotted on a telescope by astronomy students, and even radar operators at a Fort Wayne airfield having irregular activity show up on...
to adapt to statistical variations of the unknown channel. According to the LMS criterion, the updated tap-weight vector\(\hat{{{\bf{w}}}({{{\bf{n}}}+{{{\bf{1}}})\)is optimal in the meaning of mean square error40, and the updating rule is $$\hat{{{\bf{w}}}({{{\bf{n...
At left, the drawing of the LET describes the scientists’ observation, shown in the electroluminescence intensity map at right. The infrared light emitted from the LET reaches the detector, meaning that an electrical signal can be transferred to the detector by light. Credit: Shin-ichi Saito, ...
The information bottleneck method already has numerous very successful applications, such as in image and speech processing, astronomy and neuroscience [3,4,5,6]. A comprehensive tutorial on the information bottleneck method, its applications in source coding and its connections to inference and ...

Families of 2D arrays can be constructed where each array has perfect autocorrelation, and the cross-correlation between any pair of family members is optimally low. We exploit equivalent Hadamard matrices to construct many families of p p × p arr
