Bearing estimation using a large towed array
(Acoustical Society of America, 1975)When a towed array of hydrophones is significantly nonlinear due to bending, ordinary linear array beamforming gives a biased estimate of the true source bearing. By processing the array as a sequence of smaller aperture ... -
Bearing estimation using a perturbed linear array
(Acoustical Society of America, 1977-06)A linear hydrophone array which is towed in the ocean is subject to snakelike bending. If the array is processed as if it was truly linear, the author has shown that the bending causes a deflection of the measured bearing ... -
Demand for electricity in Virginia

Processing spatially aliased arrays
(Acoustical Society of America, 1978-09)A linear array can detect a plane wave signai at a wrong bearing if the signal wavelengths are shorter than twice the distance between the closest adjacent sensors. This penomenon, called spatial aliasing, is most pronounced ... -
On errors in some papers on array processing
(Acoustical Society of America, 1979-02)Some errors in the literature are noted concerning the calculation of the maximum-likelihood estimator. -
Estimating bearing when the source is endfire to an array
(Acoustical Society of America, 1979-03)Consider the problem of estimating the direction of arrival of a plane wave using a linear array of length L with M sensors. Let 0 denote the direction with respect to the array axis. Assume that we know that 0 >0. The ... -
Passive range estimation using subarray parallax
(Acoustical Society of America, 1979-05)Consider a large aperture linear array which is detecting coherent radiation from a source. Suppose that the array is processed as a string of subarrays consisting of adjacent sensors. Assume that the signal is a plane ... -
Maximum likelihood estimation of the position of a radiating source in a waveguide
(Acoustical Society of America, 1979-09)An array of sensors is receiving radiation from a source of interest. The source and the array are in a one-or two-dimensional waveguide. The maximum-likelihood estimators of the coordinates of the source are analysed under ... -
Beamforming when the sound velocity is not precisely known
(Acoustical Society of America, 1980-08)Beamforming is an integral part of most signal processingsystems in active or passive sonars. The delays used to generate a beam are functions of the sound velocity, which depends on temperature, salinity, and pressure. ... -
Frequency-wave number array processing
(Acoustical Society of America, 1981-03)Most array signal processing systems use delay-and-sum beamforming to estimate source bearings. This paper demonstrates the close relationship between beamforming and frequency-wavenumber spectrum analysis. The latter ... -
Statistical approach to passive target tracking
(Acoustical Society of America, 1981-03)The paper presents a method for passively tracking a moving target using a sequence of bearings from a surveillance platform. The key assumption for the method is that the target is moving at a constant speed on a fixed ... -
Estimating signal and noise using a random array
(Acoustical Society of America, 1982-01)This paper presents approximations for the rms error of the maximum likelihood estimator of the direction of a plane wave incident on a random array. The sensor locations are assumed to be realizations of independent, ... -
Estimating the consumption and investment demands for housing and their effect on housing tenure status
(MIT Press, 1994-02)Theoretical work suggests that families live in owner-occupied housing if their investment demand for housing exceeds their consumption demand for housing. Using household data from the 1983 Survey of Consumer Finances, ... -
Property tax capitalization in a model with tax-deferred assets, standard deductions, and the taxation of nominal interest
(MIT Press, 1999-02)Previous property tax capitalization studies assume that families itemize, that they save in taxable assets, and that real interest income is taxed. However, many families do not itemize, many families invest in tax-deferred ... -
Residential buildings and the cost of construction: new evidence on the efficiency of the housing market
(MIT Press, 1999-05)Present value studies of asset market efficiency are controversial because they compare asset prices to unobserved discounted streams of future rents. As an alternative, if housing markets are efficient, then the price of ... -
Economic models for TMDL assessment and implementation
(American Society of Agricultural and Biological Engineers, 2006)The TMDL assessment and implementation process is designed to achieve designated uses for water bodies, which are set by states based on criteria including perceived costs and benefits. Setting water quality goals based ... -
Reversal of Fortunes: The Rise and Fall of Lifetime Earnings of Iranian Men
(University of Chicago Press, 2011-07)The Islamic Revolution of 1979, the 8-year war with Iraq (1980-88), and the collapse of oil prices in 1986 dealt huge blows to Iran's economy. In this article, we use a pseudopanel constructed from annual multiple surveys ... -
Women's College Decisions: How Much Does Marriage Matter?
(University of Chicago Press, 2011-10)This article investigates the sequential college attendance decision of young women and quantifies the effect of marriage expectations on their decision to attend and graduate from college. A dynamic choice model of college ... -
What does the yield curve tell us about exchange rate predictability?
(MIT Press, 2013-03)Since the term structure of interest rates embodies information about future economic activity, we extract relative Nelson-Siegel (1987) factors from cross-country yield curve differences to proxy expected movements in ...
