This paper presents a new feature set for the problem of recognizing pulse 10 repetition interval (PRI) modulation patterns. The recognition is based upon the features 11 extracted from the multiresolution decomposition of different types of PRI modulated 12 sequences. Special emphasis is placed on the recognition of jittered and stagger type PRI 13 sequences due to the fact that these types of...

Auditory mechanisms automatically detect both basic features of sounds and the rules governing their presentation. In the oddball paradigm, the auditory system detects the sameness (or no-variability) rule when the same reference tone is consistently repeated. We used two oddball protocols, the classical one with a fixed reference and a modified one with a jittered reference, to determine wheth...

In this paper, a method of generating true random numbers obeying multiple distribution characteristics is proposed. First, two resistance-capacitance (RC) self-excited oscillation circuits are used to generate jittered, periodically unstable square wave signals, and then high-precision high-frequency quartz crystal oscillator sample measure these jittered signals obtain their periods. Due the ...

Origin-destination (OD) datasets are often represented as ‘desire lines’ between zone centroids. This paper presents a ‘jittering’ approach to pre-processing and conversion of OD data into geographic desire lines that (1) samples unique origin destination locations for each pair, (2) splits ‘large’ pairs ‘sub-OD’ pairs. Reproducible findings, based on the open source odjitter Rust crate, show r...

This paper presents an accurate and simple method to evaluate the performance of AD/DA converters affected by clock jitter, which is based on the analysis of the mean square error (MSE) between the reconstructed signal and the original one. Using an approximation of the linear minimum MSE (LMMSE) filter as reconstruction technique, we derive analytic expressions of the MSE. Through asymptotic a...

Compressed sensing (CS) or compressive sampling provides a new sampling theory to reduce data acquisition, which says that compressible signals can be exactly reconstructed from highly incomplete sets of measurements. Very recently, the CS has been applied for seismic exploration and started to compact the traditional data acquisition. In this paper, we present an optimized sampling strategy fo...

Abstract For m, d ∈ ℕ, a jittered sample of N = m points can be constructed by partitioning [0, 1] into axis-aligned equivolume boxes and placing one point independently uniformly at random inside each box. We utilise formula for the expected ℒ 2 −discrepancy stratified samples stemming from general partitions which recently appeared, to derive closed form expression set any ℕ. As second main r...

Receiver-operating-characteristic analysis was used to assess the suitability of various heart-rate variability (HRV) measures for correctly classifying electrocardiogram records of varying lengths as normal or revealing the presence of heart failure. Scale-dependent HRV measures were found to be substantially superior to scale-independent measures (scaling exponents) for discriminating the two...

Beat perception is the ability to perceive temporal regularity in musical rhythm. When a beat is perceived, predictions about upcoming events can be generated. These predictions can influence processing of subsequent rhythmic events. However, statistical learning of the order of sounds in a sequence can also affect processing of rhythmic events and must be differentiated from beat perception. I...
