Music production relies increasingly on advanced hardware and software tools that makes the creative process more flexible and versatile. The advancement of these tools helps reduce both the time and money required to create music. This paper presents research towards enhancing the functionality of a key tool, the drum machine. We add the ability to learn how to groove from human drummers, an i...

this study has been carried out to determine the accumulation of heavy metals (arsenic, copper, lead, tin and zinc) in fish samples collected from former tin mining catchment. total eight types of fish family having fifteen different species are identified. cyperinidae is the most abundant family with eight different species found in the catchment. fish samples were analysed by using inductivel...

Spatial and temporal variability in distribution and growth of newly settled red drum Sciaenops ocellatus were examined in the Aransas Estuary, Texas, USA. Overall, 1891 red drum larvae and early juveniles (4 to 30 mm standard length. SL) were identified from weekly epibenthic sled collections taken during the annual recruitment period (September-December 1994). Densities ranged from 0.0 to 3.4...

Size segregation of granular mixtures which are almost completely packed in a rotating drum is discussed with an effective simulation and a brief analysis. Instead of a 3D drum, we simulate 2D rotating thin box which is almost completely packed with granular mixtures. The phase inversion of radially segregated pattern which was found in a 3D experiment are qualitatively reproduced with this sim...

Corrosion resistance of iron can be drastically improved by addition of passivating alloying elements. A supersaturated solid solution of Fe-25at%Sn was produced by mechanical alloying of commercially pure iron and tin powders for 24 hours using a planetary ball mill. Electrochemical measurements were performed on cold compacted unsintered specimens.. XRD investigation on produced alloy showed ...

An algorithm is presented which automatically sets the attack, release, threshold, and hold parameters of a noise gate applied to drum recordings which contain bleed from secondary sources. The gain parameter which controls the amount of attenuation applied when the gate is closed is retained, to allow the user to control the strength of the gate. The gate settings are found by minimising the a...

Background: The aim of present study was to analyze the effectiveness of electron filters in the Telecobalt radiotherapy treatment by simulation technique.  Materials and Methods: The BEAMnrc Monte Carlo code was used to simulate the electron filters of thickness of 0.5 gm/cm2 below the trimmer bar for 35 × 35 cm2 field size in Theratron Equinox-80 telecobalt unit. The electron filters were mad...

In order to explore the possibility of a timbre-based rhythm theory, a drum pattern classification system was developed, which is capable of describing the internal structure of a drum groove in a stochastic way. Using an onset detection algorithm, timbral features were extracted at every drum onset of the sample file. Next, a Hidden Markov Model (HMM) was fitted to the data. Local decoding of ...
