A computationally efficient speech enhancement method is proposed. Reduction of computations is achieved due to derived properties of block model of autoregressive (AR) signal. Decreasing of filtering error in comparison with traditional Kalman filter is shown. The problem of estimation of speech AR parameters is also considered. A two-phase computationally efficient estimation procedure, based...

Nowadays, the sustainability of health care system is a relevant research topic. The works Russian scientists demon- strate lack systematic approach to determining efficiency and care. International experience data Regional Office for Europe World Health Organization (WHO) show that, despite exten- sive research, indicators have been insufficiently developed. Using methods multidi - mensional c...

the genetics and mechanism of malathion resistance in the adults of an. stephensi (ban-s), was studied. nine successive generations of malathion selection in the adults resulted in an increase in ltso of about 3-fold. the crossing experiments indicated that the resistance is inherited as partially dominant character with no indication of sex linkage. the results of back-crosses suggested that p...

Markowitz model is the first modern formulation of portfolio optimization problem. Relyingon historical return of stocks as basic information and using variance as a risk measure aretow drawbacks of this model. Since Markowitz model has been presented, many effortshave been done to remove theses drawbacks. On one hand several better risk measures havebeen introduced and proper models have been ...

In the context of globalisation, there is a need to assess difference between domestic and world price effects as an im- portant component economic analysis investment projects. We developed integrated approach measuring differences commercial public efficien cy (indicati ng pri ce effec ts) substantiat ing applicat ion specific mechanisms for implementing relevant projects based on principles ...

A 56-day feeding trial was undertaken to assess the ef-fects of housefly maggots (HM) forms (dried and fresh) as protein sources on growth, feed efficiency, body indices Oreo-chromis niloticus finger-lings. control diet (T0) contained 300 g/kg fish-meal (without HM). Two practical diets with same formula were prepared dried HM (T1) fresh (T2) where 66 % fishmeal replaced. Di-ets fed triplicate ...

A clonal rat osteogenic sarcoma cell line, UMR 106-06, was used to study the effects of retinole acid (RA) on its growth and morphology. Retinole acid caused a reversible, time and dosedependent inhibition of growth. RA-treated cells were larger, were more adherent to the substratum, and contained fewer mitotic figures. Half-maximal growth inhibition was observed at 10~8 M. Among the naturally ...

The paper presents a new method for detection of orthodontic bodies, their separation, enhancement and analysis using their plaster casts models illuminated by different light sources. The proposed method is based upon the processing of the set of two-dimensional images acquired in different illumination conditions using digital de-nosing and gradient image enhancement methods in the preliminar...

This paper analyzes performance and throughput of an adaptive bit allocation and variable rate algorithm depending on channel state information (CSI) and a transmit power in a multi-user OFDM transmission. The purpose of the presented multi-rate OFDM system using adaptive modulation is to increase bandwidth efficiency by controlling constellation size and to adapt proper service for each user a...

Over the past few years , there has b een an increasing emphasis on designing low-energy-use buildings. Rising energy prices and clim atic impacts of energy generation are among the important reasons. Super-tall buildings can be sustainable vertical cities of tom orrow, because of their high aspect ratios, efficien cy with res pect to lan d use, and reduced transportation and inf rastructure se...
