In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

An attempt to detach the worst performing schemes for improving the effectiveness of the information retrieval system, which combines the multiple sources of evidence, has been presented in this paper. The disturbances caused by the ill performing retrieval schemes are studied by using the concept of filter. The size of the filter is altered to examine the efficiency of the retrieval system. Th...

A cost-optimal nonperiodic inspection policy is derived for complex multicomponent systems. The model takes into consideration the degradation of all the components in the system with the use of a Bessel process with drift. The inspection times are determined by a deterministic function and depend on the system’s performance measure. The nonperiodic policy is developed by evaluating the expecte...

There is a growing interest in formulating vision problems in terms of Bayesian inference and, in particular, the maximimum a posteriori (MAP) estimator. This approach involves putting prior probability distributions, P (X), on the variables X to be inferred and a conditional distribution P (Y |X) for the measurements Y . For example, X could denote the position and configuration of a road in a...

This paper solves for the set of equilibrium payoffs in bargaining with interdependent values when the informed party makes all offers, as discounting vanishes. The seller of a good is informed of its quality, which affects both his cost and the buyer’s valuation, but the buyer is not. To characterize this payoff set, we derive an upper bound, using mechanism design with limited commitment. We ...

The biorthogonal 9/7 wavelet is used for lossy compression in the JPEG2000 image coding standard. A hardware implementation of the standard must consider the accuracy and the efficiency with which the quantized filter coefficients are represented; filter structure is also an important design consideration. A high precision representation ensures compression performance close to the unquantized,...

The extended Kalman filter, which linearizes the relationship between security prices and state variables, is widely used in fixed income applications. We investigate if the unscented Kalman filter should be used to capture nonlinearities, and compare the performance of the Kalman filter to that of the particle filter. We analyze the cross section of swap rates, which are mildly nonlinear in th...

Matched filter array processing (MFA) has been shown to improve signal-to-noise (SNR) quality for array speech capture in reverberant environments. However, under non-optimum conditions, MFA processing is computationally costly, and may produce little improvement or even subjective quality degradation as compared with simple time delay compensation (TDC). Appropriate truncation of the MFA filte...
