Knowing the uncertainty of measurements is important for sensor fusion using Kalman filters. Our sensor of interest is the Sick PLS101-112 laser range finder. We present an approach for straight line parameter estimation in polar coordinates that results in a simple covariance estimate and a worst case systematic line parameter error model based on a range error model backed up by experimental ...

I assessment models that combine geophysics and economics features are often used to evaluate and compare global warming policies. Because there are typically profound uncertainties in these models, a simulation approach is often used. This approach requires the distribution of the uncertain parameters clearly specified. However, this is typically impossible because there is often a significant...

There are two approaches to maximum likelihood (ML) estimation of the parameter of fractionallyintegrated noise: approximate frequency-domain ML [Fox and Taqqu (1986)] and exact timedomain ML [Sowell (1992b)]. If the mean of the process is known, then a clear finite-sample mean-squared error ranking of the estimators emerges: the exact time-domain estimator is superior. We show in this paper, h...

We study the quantum summation (QS) algorithm of Brassard, HHyer, Mosca and Tapp, see 1], which approximates the arithmetic mean of a Boolean function deened on N elements. We present sharp error bounds of the QS algorithm in the worst-average setting with the average performance measured in the Lq norm, q 2 1; 1]. We prove that the QS algorithm with M quantum queries, M < N, has the worst-aver...

this publication uses a colorimetric method based on the absorbance spectra of dye solutions to improve on beer’s law when calculating the dye concentrations of a three-component mixture. the performance of the new method is compared with that of beer’s law evaluated at three wavelengths, and beer’s law evaluated at 16 wavelengths. colorimetric method gives the best prediction of dye concentrat...

This paper will present the design, construction, and implementation of Algebraic-Geometric Irregular Block Turbo Codes (AG-IBTCs). Furthermore, we will evaluate its performance over fast fading channels using different modulation schemes (BPSK, QPSK, 16QAM, and 64QAM). The idea behind the design of AG-IBTC is to overcome the high system complexity of Algebraic-Geometric Block Turbo Codes (AG-B...

The maximum likelihood (ML) and suboptimum ML (S-ML) detectors are derived in the first order moving average model. The ML and S-ML detectors are employed in the antipodal signaling system, and compared in terms of the bit-error-rate in impulsive environment. Numerical results show that the S-ML detector, despite reduced complexity and simpler structure, exhibits practically the same performanc...

[1] Total freeboard (snow and ice) of the Arctic Ocean sea ice cover is derived using Ice, Cloud, and land Elevation Satellite (ICESat) data from two 35-day periods: one during the fall (October November) of 2005 and the other during the winter (February March) of 2006. Three approaches are used to identify near-sea-surface tiepoints. Thin ice or open water samples in new openings, typically wi...
