This paper describes a system for automatic transcription of drum instruments from polyphonic music signals. For each target drum instrument, a hidden Markov model (HMM) is created to describe the sound characteristics when the instrument is played. Also, a background model with only one state is created for each instrument to describe the sound when the target instrument is not played. The sig...

background: the purpose of this research was to determine the traffic noise level and changes in the kerman city, southeast iran in recent years. methods: this cross-sectional study was carried out in 2008 to investigate the existing noise situation in kerman. sound levels (l max , l min , l eq , l 99 , l 90 , l 50 and l 10 ) were determined throughout 13 stations using sound level measurement ...

A method for producing narrow-band THz radiation proposes passing an ultra-relativistic beam through a metallic pipe with small periodic corrugations. We present results of a measurement of such an arrangement at Brookhaven’s Accelerator Test Facility (ATF). Our pipe was copper and was 5 cm long; the aperture was cylindrically symmetric, with a 1 mm (radius) bore and a corrugation depth (peak-t...

Wheat grain quality assessment is important in meeting market requirements. The thickness of grains can be used for the measurement of the mass proportion of grains that pass through a sieve. This measure is known as ‘‘screenings’’. The determination of the presence or absence of the grain crease aids the detection of a stain called blackpoint, which is usually most evident on the non-crease si...

introduction integrated nutrient management involving crop residue/green manures and chemical fertilizer is potential alternative to provide a balanced supply of nutrients, enhance soil quality and thereby sustain higher productivity. the present experiment was undertaken to evaluate the effect of different crop residue management practices and npk levels on yield components and yield of wheat....

Lysophospholipids (LPLs) are the most abundant polar lipids in wheat endosperm and naturally complex with amylose, affecting starch physicochemical properties. We analyzed LPLs in wheat flour from 58 cultivars which differ by grain hardness using liquid chromatography mass spectrometry (LCMS). There were significant differences in LPL content between cultivars, demonstrating that genotype rathe...

Hrušková M., Švec I. (2009): Wheat hardness in relation to other quality factors. Czech J. Food Sci., 27: 240–248. The analysis of the wheat hardness relation to other quality features was done with a set of 281 variety and commercial wheat samples, planted during the years of 2003–2006 in Central Bohemia and south Moravia areas. Technological quality was evaluated for grain, milling process, a...

This paper describes the findings of selenium measurement in three types of soil (semigley, pseudogley and hypogley) and in wheat grain cultivated in these types of soil in the vicinity of Koprivnica using hydrid atomic absorption spectrometry. The results showed relatively low selenium levels in all three types of soil (145-333 micrograms Se/kg dry weight) as well as the wheat grain (22-62 mic...
