Plant disease detection is a branch of fine-grained problems that can be expressed using the t-SNE (t-Distributed Stochastic Neighbor Embedding) algorithm [6] to indicate the class separability and compactness in features extracted from a convolutional neural network [7]. The t-SNE visualization ...
Frequency, the number of waves that pass a fixed point in unit time; also, the number of cycles undergone during one unit of time by a body in periodic motion. A body in periodic motion is said to have undergone one cycle after passing through a series o
The magnetic field gradient is expressed in MHz per pixel. b ODMR of the \(\left|0\right\rangle \to \left|-1\right\rangle\) transition at the GSLAC. The field of view corresponds to a bandwidth between 10 MHz and 250 MHz. c ODMR of the \(\left|0\right\rangle \to \left|...
Absolute frequency is astatisticalterm describing the number of times a particular piece of data or a particular value appears during a trial or set of trials. Essentially, absolute frequency is a simple count of the number of times a value is observed. Absolute frequency is usually expressed as...
In subject area: Computer Science Frequency Division Multiple Access (FDMA) is a scheme used to provide multiple access in which different users are separated by assigning them different carrier frequencies. In FDMA, signals from various users are assigned different frequencies, allowing for isolation ...
Signal waveform is the basic physical layer element that fundamentally determines the most important key performance indicator in communication systems, namely spectral efficiency. Traditional waveforms rely on orthogonal Nyquist shaping but result in re
Again, strength is expressed in a logarithmic scale using decibels (dB). RF signal strength (or RF “signal”) is expressed as dBm, with a reference of 1 mW of RF power. That is, 0 dBm = 1 mW RF power. RF signal strength in dBm is the logarithm of the RF power in mW. dBm=...
Manipulations of multiple carrier frequencies are especially important in a variety of fields like radar detection and wireless communications. In conventional radio-frequency architecture, the multi-frequency control is implemented by microwave circuits, which are hard to integrate with antenna apertures, ...
For example, it is unclear whether information about stimulus frequency is perturbed by adaptation or encoded by precise response timing. We addressed this question in rat barrel cortex by comparing performance in behavioral tasks with either whisker stimulation, which causes frequency-dependent adaptation...
21 and corrections to the LNA-based PSD estimates were systematically derived in ref. 22. Even though SDE approximations make the problem of computing the PSD analytically tractable, their accuracy is severely compromised if any of the species are in low copy-numbers, as is the case for many ...
