This paper proposes a new nonparametric method for estimation of spectral moments of a zero-mean Gaussian process immersed in additive white Gaussian noise. Although the technique is valid for any order moment, particular attention is given to the mean Doppler (first moment) and to the spectral width (square root of the centered second-spectral moment). By assuming that the power spectral densi...

A new method, namely universal compensation (UC), is introduced for speech recognition involving additive noise assuming no knowledge about the noise. The UC method involves a novel combination of the principle of multi-condition training and the principle of the missing-feature method. Multicondition training is employed to convert full-band spectral corruption into partial-band spectral corru...

Ambient air quality datasets include missing data, values below method detection limits and outliers, and the precision and accuracy of the measurements themselves are often unknown. At the same time, many analyses require continuous data sequences and assume that measurements are error-free. While a variety of data imputation and cleaning techniques are available, the evaluation of such techni...

The application of low-density parity-check (LDPC) codes for use in high-density magnetic recording channels is considered. A first order position jitter model is assumed in order to include the effect of signal dependent transition noise present in high density longitudinal thin film recording. Coding gains using pattern dependent noise-predictive soft detection to account for the transition n...

In this paper we consider the eeect of timedelay in the performance of the AIMD algorithm, speciically queue length and fairness for both rate and window based sources. The queue bounds can be used to allocate buuers at bottlenecks so that ows can go through without any loss.We modify the AIMD algorithm by making the additive rate increase parameter proportional to the round trip time and the d...

X-Ray Polarimetry can be now performed by using a Micro Pattern Gas Chamber in the focus of a telescope. It requires large area optics for most important scientific targets. But since the technique is additive a dedicated mission with a cluster of small telescopes can perform many important measurements and bridge the 40 year gap between OSO-8 data and future big telescopes such as XEUS. POLARI...

Laser additive manufacturing (LAM) is rapidly becoming an important method for the fabrication of both prototype and production metal parts. However, the technology is really just in its infancy, and significant work still needs to be done in the development of new materials and in understanding how various process parameters affect results. In particular, LAM methods typically have a relativel...

water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...

Differentiation-inducing agents, such as retinoids and short-chain fatty acids, have an inhibitory effect on tumor cell proliferation and tumor growth in preclinical studies. Clinical trials involving these compounds as single agents have been suboptimal in terms of clinical benefit. Our study evaluated the combination of phenylbutyrate (PB) and 13-cis retinoic acid (CRA) as a differentiation a...
