PURPOSE The mouse eye has become an important model in vision research. However, it is not known how visual acuity changes with luminance. Therefore, grating acuity of mice was measured at different luminances in an automated optomotor paradigm. Furthermore, mutant mice lacking either rods (RHO-/- and CNGB1-/-) or cones (CNGA3-/-), or both, were studied to determine the rod and cone contributio...

The influence of different internal geometries on the solid flow in rotary drums under variation operational parameters feed rate, slope, and rotational speed is investigated. Four configurations a fully optically accessible lab-scale drum are analyzed. internals built as sectional compartments cross section, referring to industrial applications. axial dispersion model used calculate mean resid...

While Prior Subspace Analysis (PSA) has proved an effective tool for transcribing mixtures of snare, kick drum and hi-hat both in the “drums-only” case and in the presence of pitched instruments attempts to extend it to deal with increased numbers of drum types have met with mixed results. To overcome this an automatic modeling and grouping procedure has been developed which groups drum events ...

Due to the great differences in mechanical properties between hard concretion and coal, shearer drum cutting coal rock containing will inevitably lead a series of problems, such as severe load impact, increased specific energy consumption low loading efficiency. Taking part thin seam service target mining area prototype, models rocker arm are established by using UG, discrete element model wall...

We examined the patterns of habitat-specific mortality for newly settled red drum (Sciaenops ocellatus) using an experimental mesocosm approach. Experiments were designed to analyze prey vulnerability and fish rearing-type (wild-caught or hatchery-reared) in estuarine habitats of varying structural complexity including marsh (Spartina alterniflora Loisel), oyster reef (Crassostrea virginica Gme...

A soft-sphere discrete particle model was used to simulate mixing behavior of solid substrate particles in a slow rotating drum for solid-state fermentation. In this approach, forces acting on and subsequent motion of individual particles can be predicted. The (2D) simulations are qualitatively and quantitatively validated by mixing experiments using video and image analysis techniques. It was ...

This paper will describe the design and implementation of PadMaster, a real-time improvisation environment running under the NextStep operating system. The system currently uses the Mathews/Boie Radio Drum as a three dimensional controller for interaction with the performer. PadMaster splits the surface of the drum into virtual programmable pads which can be grouped into scenes so that the beha...

Economic analysis allows for determining the required daily output under certain natural and mining conditions based on costs of production process in a particular mine infrastructure. Therefore, there is need to determine potential longwall using technical equipment at disposal mine. In case mines, when exploiting few longwalls simultaneously bumping hazards, it indispensable ensure safety. Du...
