Introduction: A neutrino observatory planned for South Pole offers an opportunity to collect a timesequenced 100,000-yr record of micrometeorites and terrestrial dust deposited in Antarctic ice with 20–100yr resolution. This unprecedented record bears on numerous studies including the evolution of near-Earth cosmic-dust and the provenance of micrometeorites, the relationship between ET influx a...

In many practical Kalman filter applications, the quantity of most significance for the estimation e m r w the process noise matrix. When filters are stabilized or performance is sought improved, tuning of this matrix is the most common method. This tuning process cannot be done before the filter is implemented, OS it is primarily made necessary by modelling errors. In this paper two different ...

Empirical tests have been developed for evaluating the numerical properties of multirate M -band filter banks represented as N×M matrices of filter coefficients. Each test returns a numerically observed estimate of a 1×M vector parameter in which themth element corresponds to themth filter band. These vector valued parameters can be readily converted to scalar valued parameters for comparison o...

Urban storm water runoff poses a substantial threat of pollution to receiving surface waters. Green infrastructure, low impact development, green building ordinances, National Pollutant Discharge Elimination System (NPDES) storm water permit compliance, and Total Maximum Daily Load (TMDL) implementation strategies have become national priorities; however, designers need more sustainable, low-co...

A propeller-wash bead filter (PWBF) and a fluidized sand filter (FSF) on a 28 m recirculating system stocked with tilapia maintained favorablewater quality at five different feed rates, ranging from 0.9 to 4.5 kg feed per day. TAN removal rates ranged up to about 200 g TAN/m of media per day for each of the units. Peak rates of 244 g TAN/m of media per day were observed when the recirculating f...

In this paper, we propose a new M-channel wavelet bases called the cosine-modulated wavelets. We first generalize the theory of two-channel biorthogonal compactly supported wavelet bases to the M-channel case. A sufficient condition for the M-channel perfect reconstruction filter banks to construct M-channel compactly supported wavelet bases is given. By using this condition, a family of orthog...

Combining the methods of generating functions and discrete-time linear systems, we can develop multidimensional (M-D) digital systems for systematic generation of entire families of interrelated digital filters. These M-D systems, dubbed filter-generating systems, are mostly of infinite-impulse response (IIR) type and can produce the impulse response sequence of any member of the family. Tempor...

This paper presents the m e w of sensor fusion based on the Adaptive Fuzzy Kalman Filtering. This method has been applied to fuse position signals from the Global Positioning System (GPS) and Inertial Navigation System (INS) for the autonomous mobile vehicles. The presented method has been validated in 3-0 environment and is of particular importance for guidance, navigation, and control of flyi...

Given the importance of IT investments in today’s organization, firms tend to spend increasing amounts of time and resources to better manage IT projects. However these projects continue to have high failure rates thus highlighting the need for improved risk management. A stream of IS research has focused on identifying several causes of managerial risks. The theory base that has been used in t...
