We develop WASSP, a wavelet-based spectral method for steady-state simulation analysis. First WASSP determines a batch size and a warm-up period beyond which the computed batch means form an approximately stationary Gaussian process. Next WASSP computes the discrete wavelet transform of the bias-corrected log-smoothed-periodogram of the batch means, using a soft-thresholding scheme to denoise t...

LADA, EMILY KATE. A Wavelet-Based Procedure for Steady-State Simulation Output Analysis. (Under the direction of Dr. James R. Wilson.) The objective of this research is to develop an automated sequential procedure by which an asymptotically valid confidence interval is constructed for the steady-state mean of a simulation output process. This procedure, called WASSP, determines a batch size and...

A and an analysis are given for an experimental performance evaluation of WASSP, an automated wavelet-based spectral method for constructing an approximate confidence interval on the steady-state mean of a simulation output process such that the delivered confidence interval satisfies user-specified requirements on absolute or relative precision as well as coverage probability. The experimentat...

We develop an automated wavelet-based spectral method for constructing an approximate confidence interval on the steady-state mean of a simulation output process. This procedure, called WASSP, determines a batch size and a warmup period beyond which the computed batch means form an approximately stationary Gaussian process. Based on the log-smoothed-periodogram of the batch means, WASSP uses wa...

Nine datasets make up the Common Dataset acquired by Edgetech, Kongsberg, Teledyne Reson and WASSP in 2014. This paper aims to assess the ability of the systems to detect objects using both visual and statistical analysis. The paper will present the findings of the authors dissertation.

Marine litter is a growing threat to the marine environment. Mapping of becoming increasingly important detect its potential hotspots and prevent their spread. In this paper, applicability multibeam echo sounder (MBES) WASSP S3 remotely operated underwater vehicle (ROV) Chasing M2 was tested in detection mapping on seafloor within wider area St. Ante Channel (Šibenik, Croatia). Also, precision ...

Multibeam echosounders (MBES) have become a valuable tool for underwater floor mapping. However, MBES data are often loaded with different measurement errors. This study presents new user-friendly and methodological semi-automatic approach of point cloud post-processing error removal. The St. Anthony Channel (Croatia) was selected as the research area because it is regarded one most demanding s...
