A method for comparing discrete kinematic data and N-body simulations
نویسنده
چکیده
As an example, I consider a published N-body model for the Galactic bulge and disc, and fictitious l, b, v measurements, and recover (with error estimates) the spatial and velocity scales of the model and the orientation of the bar. The fictitious data are actually derived from the model by assuming the mass scale and the solar position, but their size and extent mimics a recent survey of OH/IR stars. The results indicate that mass of the bulge and our viewing angle of the bar are usefully estimable from current surveys.

Anticipation in Baseball: Differences in Using Spatial Cues between Skilled and Novice Players
The purpose of this investigation was to examine the differences between novice and skilled baseball players to anticipate the type of ball being pitched and to specify the players’ dependence on distributed or local kinematic spatial cues. Male baseball players (N= 15; Mage: 27.73 ± 6.28 years; baseball experience: 7.90 ± 5.69 years) and novices (N= 15; Mage: 23.10 ± 5.68 years; no playing exp...

The discrete element method (DEM) has been used as a popular simulation method in order to verify the designs by visualizing how materials flow through complex equipment geometries. Although DEM simulation is a powerful design tool, finding a DEM model that includes all real material properties is not computationally feasible. In order to obtain more realistic results, particle energy loss du...

Discrete Element Method (DEM) is extensively used for mathematical modeling and simulating the behavior of discrete discs and discrete spheres in two and three dimensional space, respectively. Prediction of particles flow regime, power draw and kinetic energy for a laboratory or an industrial mill is possible by DEM simulation. In this article, a new approach was used to assess the main paramet...
متن کاملPresentation of K Nearest Neighbor Gaussian Interpolation and comparing it with Fuzzy Interpolation in Speech Recognition
Hidden Markov Model is a popular statisical method that is used in continious and discrete speech recognition. The probability density function of observation vectors in each state is estimated with discrete density or continious density modeling. The performance (in correct word recognition rate) of continious density is higher than discrete density HMM, but its computation complexity is very ...
