In natural speech, for a given speaker, vocal tract length (VTL) is effectively fixed whereas glottal pulse rate (GPR) is varied to indicate prosodic distinctions. This suggests that VTL will be a more reliable cue for identifying a speaker than GPR. It also suggests that listeners will accept larger changes in GPR before perceiving speaker change. We measured the effect of GPR and VTL on the p...

A new recombination operator, called Gene Pool Recombination (GPR) is introduced. In GPR, the genes are randomly picked from the gene pool defined by the selected parents. The mathematical analysis of GPR is easier than for two-parent recombination (TPR) normally used in genetic algorithms. There are n difference equations for the marginal gene frequencies that describe the evolution of a popul...

A 30 m by 30 m two-dimensional grid was designed on a flat bench behind a quarry face of predominantly limestone with thin shale layers located at a Bonner Springs, Kansas site to test the utility of ground-penetrating radar (GPR) for stratigraphic studies. GPR data were collected along seven lines parallel to the quarry face and seven lines perpendicular to the quarry face, each separated by 5...

AIM To investigate the value of the gamma-glutamyltraspeptidase (GGT)-to-platelet (PLT) ratio (GPR) in the diagnosis of hepatic fibrosis in patients with chronic hepatitis B (CHB). METHODS We included 390 untreated CHB patients in this study. The GPR, aspartate aminotransferase (AST)-to-PLT ratio index (APRI), and fibrosis-4 (FIB-4) of all patients were analysed to determine if these paramete...

Precise models of the robot inverse dynamics allow the design of significantly more accurate, energy-efficient and more compliant robot control. However, in some cases the accuracy of rigidbody models does not suffice for sound control performance due to unmodeled nonlinearities arising from hydraulic cable dynamics, complex friction or actuator dynamics. In such cases, estimating the inverse d...

Recent work on scaling up Gaussian process regression (GPR) to large datasets has primarily focused on sparse GPR, which leverages a small set of basis functions to approximate the full Gaussian process during inference. However, the majority of these approaches are batch methods that operate on the entire training dataset at once, precluding the use of datasets that are streaming or too large ...

Introduction: The thickness of the lunar regolith and potential for frozen water are important considerations for future lunar outposts. However, the thickness of the regolith is largely unknown and the presence of water ice has yet to be directly detected at or beneath the surface. A rapid and economical geophysical method to determine both the thickness of the lunar regolith and possibly iden...

Ground penetrating radar (GPR) has been widely used in geologic, hydrogeologic, and civil engineering purposes. Correlated with geological exposures and trenches, GPR data can offer detail subsurface information to past earthquakes investigation. McClymont et al. [2][3] show very good performance of GPR for fault characterization. In this paper, we show an example of practical application of GP...

Abstract Lithium-ion batteries have been widely used in renewable energy storage and electric vehicles, state-of-health (SoH) prediction is critical for battery safety reliability. Following the standard SoH routine based on charging curves, a human-knowledge-augmented Gaussian process regression (HAGPR) model proposed by incorporating two promising artificial intelligence techniques, i.e., (GP...

Abstract. Ground-penetrating radar (GPR) is widely used for determining mountain glacier thickness. However, this method provides thickness data only along the acquisition lines, and therefore interpolation has to be made between them. Depending on strategy, calculated ice volumes can differ lack an accurate error estimation. Furthermore, glacial basal topography often characterized by complex ...
