A method for reducing excessive constant-fraction-discriminator walk that utilizes experimental data in the off-line analysis stage is introduced. Excessive walk is defined here as any walk that leads to an overall timing resolution that is much greater than the intrinsic timing resolution of the detection system. The method is able to reduce the contribution to the overall timing resolution fr...

A discriminator circuit uses dual current sources charging a capacitor to produce an output timing edge a fixed time after the starting corner of the input pulse, nearly independent of risetime and threshold setting. Performance with artificial and real pulses in the microsecond range is described. Background Obtaining a good timing information from slow-rising pulses is an old problem in pulse...

A software routine to reconstruct individual spike trains from multi-neuron, single-channel extracellular recordings was designed. Using a neural network algorithm that automatically clusters and sorts the spikes, the only user input needed is the threshold level for spike detection and the number of unit types present in the recording. Adaptive features are included in the algorithm to allow f...

Target tracking is prone to problems such as target loss and identity jump when the occluded attitude changed. In order solve this phenomenon, paper proposes adaptive adjustment object detection algorithm under multiple mechanisms based on GAN. This introduces a gradient penalty mechanism discriminator uses relative structure reconstruct discriminator, so improve discriminatory ability of discr...

The multipath effect can severely reduce the positioning accuracy of GNSS receivers. Thus, it is very important to estimate and mitigate delay error in tracking algorithms, especially harsh environments. code phase highly related performance. Especially, absolute position results are dependent on term phase. However, seldom discussed processed state-of-the-art methods. In this paper, proposed f...

Tracking error estimation is of great importance in global navigation satellite system (GNSS) receivers. Any inaccurate estimation for tracking error will decrease the signal tracking ability of signal tracking loops and the accuracies of position fixing, velocity determination, and timing. Tracking error estimation can be done by traditional discriminator, or Kalman filter-based pre-filter. Th...

Some of the promising End-To-End solutions to improve TCP performance over networks suffering from wireless transmission errors are error discriminators. An error discriminator is any technique that tries to differentiate between error types and deal with each type differently. By distinguishing between error types, TCP can avoid unnecessary cuts of congestion window in the case of wireless err...

Frequency discriminators are widely used in electronic warfare systems for the instantaneous frequency measurement of intercepted signals, allowing rapid identification of threat emitters. This paper reviews microwave discriminator architectures based on multiple delay line, phase measurement with parallel digital processing, for operation over decade bandwidths. An alternative reflection mode ...

The variety DQD of semi-Heyting algebras with a weak negation, called dually quasi-De Morgan operation, and several of its subvarieties were investigated in the series [31], [32], [33], and [34]. In this paper we define and investigate a new subvariety JID of DQD, called “JI-distributive, dually quasi-De Morgan semi-Heyting algebras”, defined by the identity: x ∨ (y → z) ≈ (x ∨ y) → (x ∨ z), as...
