	SolveigMM AVI Trimmer Component  License: Freeware
	Solveig Multimedia AVI Trimmer Component is an engine designed for nonlinear editing of AVI files, implemented as COM object based on Microsoft® DirectShow®. Version 1.0 allows a developer to cut the part of an input AVI file with specified start/stop time positions and save it to an output AVI file. The component package has all necessary binaries, Developer Reference Manual and Visual C++ application sample code, that demonstrates an usage of SolveigMM AVI Trimmer Component. SolveigMM AVI Trimmer Component v.1.0 features: Supports any video content (DV, XviD, DivX, 3ivX, etc…) Supports any audio content (MPEG-1, MPEG-2 layer 2,3, AC3, etc…) Allows trimming AVI files contained VBR audio without synchronization loss Supports AVI files of the size more then 2GB Supports the OpenDML AVI file format extension Supports the native DV AVI format (both Type 1 and Type 2 in Microsoft terms) Performs the trimming process starting with K frame Author: Solveig Multimedia| Date: 01-01-2005 | Size: 500 KB

	RF21  License: Freeware
	RF21 for Windows is a scientific calculator, plotter, programming and numeric system in one. It allows for permanent installation of a user's own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago. Each function self-reassembles when its name is called, autonomously searching the libraries for all components needed. Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including: Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, n-dimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer. Fast screenplots and an environment for designing printable plots, which may as well be exported to -.GIF and -.BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields. Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see author's homepage for a systematic reference of these.

	RaptorAssist  License: Freeware
	Raptor Edit captures files pretty good. But it uses a clumsy naming scheme. Because many video editing software packages use alphabetical lists, your files appear in alphabetical rather than chronological order. RaptorAssist cures this by renaming your files suitably.

	CurTiPot Acid-Base pH and Titration  License: Freeware
	A pH Calculator, a Virtual Titrator, a Real Titration Data Analyzer, a Distribution Diagram Generator - that's CurTiPot, the all-in-one freeware to learn, teach and work with chemical equilibrium of acids, bases, salts and buffers at home, classroom, interactive "dry lab" or research laboratory. Features of this powerful suite of MS Excel spreadsheets embrace: - pH calculation of any aqueous solution of strong and weak acids, bases, salts, buffers and mixtures of up to 7 polyprotic systems (>40 species), with activity coefficient estimation; - Simulation and overlay of acid-base titration curves of any complexity, with or without random errors in pH and/or volume. Valuable for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of new titrations. - Analysis of pH vs. volume data from simulated and real potentiometric titration curves by two methods: i) graphical representation of curves, assisted by cubic splines interpolation and smoothing of derivative curves, for accurate evaluation of inflections (end-points); ii) determination of concentrations and refinement of pKa values by multiple nonlinear regression (based on the Solver supplement of Excel), essential for difficult titrations with undefined inflections, e.g., acid rain. - Generation of protonation curves and distribution diagrams of equilibrium species of acids and bases at equilibrium as a function of pH or of added volume of titrant. - Expandable database with pKa values of 250 acids and bases. Simply unzip the curtipot_.xls file, open it with Microsoft Excel (at medium security level), activate macros and start learning, working and teaching. No install/uninstall required, all macros are removed when closing file. The software is completely free for educational and non-commercial use. Author: Ivano G. R.
