	4IE Internet Macros Web Testing PlugIn  License: Freeware
	The Web browser is probably the most frequently used software today, and many tasks are highly repetitious. Internet Macros relieves the repetition of checking on the same sites every day, remembering passwords and filling out web forms. It is the only web form filler, that can automatically fill web forms that stretch over several pages. Passwords are stored securely with 256-Bit AES encryption. Web professional can use the software for functional testing and regression web testing of web applications. It can also be used to automate web data extraction, for example online stock quotes or web store prices. Author: IM Scripting Web Testing and Data Extraction| Date: 14-03-2005 | Size: 2624 KB

	Numap7  License: Freeware
	Freeware for fast training, validation, and application of regression/approximation networks including the multilayer perceptron (MLP), functional link network, piecewise linear network, self organizing map (SOM) and K-Means clustering. C source code for applying trained networks is provided, so users can use networks in their own applications. User-supplied txt-format training data files, containing rows of numbers, can be of any size. Example training data is also provided. Fast VB Graphics for network training error and cluster formation are included. Extensive help files are provided in the software. Numap7 is highly automated and requires very few parameter choices by the user. Advanced features include a fast MLP training algorithm (faster and better than BP and LM), input feature selection, pruning (elimination) of useless units (for MLP) and modules for PLN). Training and validation error are plotted versus network size. Utilities are provided for counting patterns, deleting columns, combining files, splitting files, calculating column mean and standard deviation, and plotting column histograms. Training data can be compressed using the discrete Karhunen-Loeve' transform (KLT). This freeware version of Numap7 limits the MLP to 10 hidden units and limits the PLN to 10 clusters. Upgradable to the commercial version, which lacks these limitations. The classification (decision making) version of this software, called Nuclass7, is also available. Numap7.0 was developed by the Image Processing and Neural Networks Lab of Univ. of Texas at Arlington, and by Neural Decision Lab LLC.

	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.
