Free estimation software for windows

MSU Noise Estimator 0.1 is an ideal tool for anyone who has to work with audio a great deal. It is actually a free MSU VQM plugin for noise level estimation. It includes implementation of three most popular algorithms for measurement of noise level. By results of job of the metrics the plot of frame-accurate value of noise level is constructed. Final value of the metrics is average arithmetic of all frame-accurate values.

Algorithms:

• MAD - For each frame do HAAR wavelet decomposition. Than evaluate median of HH-component's absolute values. Final value of the metrics is the normalized median.
• Block-Based - Frames are tessellated into a number of 8x8 blocks. Standard deviations of intensity (measures of intensity variation) are computed for all the blocks and sorted. The block with the smallest standard deviation has the least change of intensity. The smaller the standard deviation, the smother the block. The intensity variation of a smooth block may be due to noise, in which the standard deviation of the block is close to that of the Gaussian noise added. Normalized average arithmetic values of 30 % of all blocks with the least values grows is the final value of the metric.
• Spatio-Temporal Gradients - For each frame is doing wavelet decomposition. computing temporal and spatial histograms. The initial estimation of noise level is defined by value at which temporal or spatial histogram achieves the maximal value. The decision of whether to use the spatial or temporal histogram is based on the deviation of the histogram from the Rayleigh distribution. Then this estimation is corrected, using Kolmogorov-Smirnoff test. The normalized corrected estimation is the final value of the metric.

MDDS-Simulator is a software simulator of dynamic systems.
The name stands for Mathematically Described Dynamic Systems - Simulator.
MDDS-Simulator can be used for solving chemical engineering problems - having to do with chemical kinetics, mass and heat transfer, hydraulics and so on but it can be also used in many other fields, for example, mechanical, physiological, biological, economical.
This simulator uses previously developed mathematical models describing the behavior of a dynamic system examined and shows the changes in that system. MDDS-Simulator answers the question "Whats going on?" so it gives information for changes of some important system parameters. For example - concentrations of reacting and (or) resulting substances. Using MDDS-Simulator you can solve first and second order time derivative equations. Straightforward equations and equations with arbitrary parameter combinations can also be calculated. Furthermore, MDDS-Simulator can be used for optimization of system parameters - estimation of up to three parameters per one optimization run. The program manipulation is realized through user-friendly graphical interface. The model input is developed in a logically-consecutive way. The program has two types of model outputs - numerical results and graphical screen.
The program has a tool for calculation of confident intervals.
