A 3D approximate maximum likelihood localization solver
Abstract
A robust threedimensional solver was needed to accurately and efficiently estimate the time sequence of locations of fish tagged with acoustic transmitters and vocalizing marine mammals to describe in sufficient detail the information needed to assess the function of dampassage design alternatives and support Marine Renewable Energy. An approximate maximum likelihood solver was developed using measurements of time difference of arrival from all hydrophones in receiving arrays on which a transmission was detected. Field experiments demonstrated that the developed solver performed significantly better in tracking efficiency and accuracy than other solvers described in the literature.

Better understanding of fish behavior is vital for recovery of many endangered species including salmon. The Juvenile Salmon Acoustic Telemetry System (JSATS) was developed to observe the outmigratory behavior of juvenile salmonids tagged by surgical implantation of acoustic microtransmitters and to estimate the survival when passing through dams on the Snake and Columbia Rivers. A robust threedimensional solver was needed to accurately and efficiently estimate the time sequence of locations of fish tagged with JSATS acoustic transmitters, to describe in sufficient detail the information needed to assess the function of dampassage design alternatives. An approximate maximum likelihood solver was developedmore »Cited by 6

Approximate tolerance intervals, based on maximumlikelihood estimates
Let X/sub 1/,..., X/sub n/ be independent random variables with distributions depending on a possibly multidimensional theta. Let Y be an unobserved continuously distributed random variable whose distribution depends on theta. A tolerance interval for Y is desired, satisfying P(Yepsilon I(X/sub 1/,...,X/sub n/)) = ..beta... A naive interval would estimate theta from the X's, and construct the interval assuming that the estimate is exactly correct. This paper assumes standard regularity conditions, and uses Taylor approximations to construct correction terms of order l/n. The resulting interval is longer than the naive interval, because it takes into account the uncertainty in themore » 
Using an approximate Riemann solver with the maximum entropy closure
The authors briefly describe the solution of the zeroth and first moment equations of particle transport with Minerbo`s maximum entropy closure using a Riemann solver. This solver properly accounts for the direction and speed of propagation of information in this highly nonlinear hyperbolic system. While a direct iteration on the Eddington factor can become unstable and produce unphysical solutions, timestepping to steady state with a Riemann solver has shown no such unphysical behavior. This establishes that the Minerbo closure is a useful twomoment transport approximation even in strong absorbers. It also establishes the utility of examining the hyperbolic structure ofmore » 
Maximum Likelihood ExpectationMaximization Algorithms Applied to Localization and Identification of Radioactive Sources with Recent Coded Mask Gamma Cameras
In this work, we tested Maximum likelihood expectationmaximization (MLEM) algorithms optimized for gamma imaging applications on two recent coded mask gamma cameras. We respectively took advantage of the characteristics of the GAMPIX and Caliste HDbased gamma cameras: noise reduction thanks to mask/antimask procedure but limited energy resolution for GAMPIX, high energy resolution for Caliste HD. One of our shortterm perspectives is the test of MAPEM algorithms integrating specific prior values for the data to reconstruct adapted to the gamma imaging topic. (authors)
