Model Of An Atom

This tutorial starts with a simple conceptual model of an analog Phase-Locked Loop (PLL). Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both ANSI C or synthesizable HDL).The step-wise...

If you travel deep into microcosmos inside the nucleus of an atom into the world of the quarks, you might see these visuals. Let yourself be hypnotized by this never ending flow of Nuclear visions.

This is a demo program of the paper J. Tian and L. Chen, "Image despeckling using a non-parametric statistical model of wavelet coefficients," Biomedical Signal Processing and Control, Vol. 6, No. 4, Oct. 2011, pp. 432-437.

In pattern recognition, and in particular multiple classifier systems, a common problem is to calculate competence of a classifier for a given object. Methods for calculating the competence currently developed are based only on crisp decision of the classifier, i.e. correct/incorrect...

Plot streamlines and pressure coefficent of an unviscious, uncomprimibile,irrotational flow around a cylinder section (r=1) that spins around the z axis (coming out of the xy plane). This result is achieved by superimposition of elementary solution of the potential function PHI, where [Ux , Uy] =...

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

The Newton's Law of Cooling model computes the temperature of an object of mass M as it is heated by a flame and cooled by the surrounding medium. The model assumes that the temperature T within the object is uniform. This lumped system approximation is valid if the rate of thermal energy...

The Ejs Pendulum on an Accelerating Train model displays the model of a pendulum on an accelerating train. The problem assumes that the pendulum rod is rigid and massless and of length, L = 2, and the pendulum bob is of mass, m = 1. The initial pendulum angle and the initial velocity of the train...

The zip file includes the model description in a pdf file, a simulink model of the steam condenser, a function to perform Reaction Curve PID tuning and an m-file to run the model.The m-file can be used to learn how to use the Reaction Curve approach to tune a PID controler. The model itself can...

This paper presents the empirical modeling of thegaseous pilot plant which is a kind of interacting series processwith presence of non linearities. In this study, the discrete-time identification approach based on subspace method with N4SIDalgorithm is applied to construct the state space model...

The Ejs Phase Space Plotter model displays the dynamics of an ensemble of pendula or simple harmonic oscillators in phase space (velocity versus position). Friction is initially set to zero but can be changed via a textbox as can the number of elements in the ensemble. For the pendulum ensemble,...
