	RadioWORKS  License: Freeware
	RadioWORKS is a tool for calculating various items related to radio waves and radio wave propagation. Get detailed information about a frequency, such as the free-space wavelength, proper antenna lengths for common wavelength ratios, band classification, propagation methods, common transmitter configurations, etc. Calculate path loss using the Free-Space, Flat-Earth, ITU Terrain, Hata Urban, Hata Suburban, Hata Open Area, or Empirical COST-Walfisch-Ikegami (Also known as 'COST 231') non Line-of-Sight (n-LoS) and Line-of-Sight (LoS) mathematical models -- OR -- run the models backwards to get the matching distance for a given path loss value. Use the Distance and Power change prediction calculator to predict how a proposed transmitter power change, whether an increase or a decrease, will affect your usable range -- OR -- how a proposed range requirement change, whether an increase or a decrease, will affect your transmitter power requirements, while factoring in the signal decay rate observed in your current system. All path loss & distance / power change prediction calculations can also be displayed graphically. Context-sensitive help is available to guide with the usage of the various calculators. Additionally, all mathematical formulas used by the application are on display, including explanations and usage information. RadioWORKS is made available as FREEWARE. It contains no virii, adware, spyware, back doors, or trojans. RadioWORKS is packaged as an MSI (Microsoft Installer) file for easy installation and removal.

	Formulator Express  License: Freeware
	Formulator is a powerful interactive mathematical expressions editor. It uses WYSIWYG-style editing and allows creating mathematical equations through simple point-and-click techniques. Formulator is the intelligent software, aware of presentation or semantics face of mathematics. Advanced editing features are available by means of MathML authoring techniques which help Formulator to implement effective solutions for a wide audience of software developers, educators, students, STM publishers, etc. Among the distinguishing features of Formulator is component versions support (in the form of ActiveX Control or Automation Server) and extensive support of MathML 2.0 (Presentation, Content and Mixed markups) through easy-to-use graphical interface. Exporting functionality of Formulator is extremely useful when a user wants to share you math documents. With the help of Formulator users have a freedom to publish their work in so different ways as MathML plain text fragments, XHTML documents with MathML inlined, raster images, vector graphics (EMF). Formulator is visually oriented tool. It proposes intuitive and easy-to-use ways to create and edit both Presentation and Content MathML markups. Comprehensive collection of mathematical symbols and templates of Formulator is useful both to users having publishing needs and to those who is oriented on analysis of expressions meaning. Field of applications for Formulator is really wide, since it comprises both a standalone application edition, run as a separate program, and a component edition, that is, an ActiveX control. When using the Formulator ActiveX Control this revolutionary functionality makes it simple to develop new software products, keenly aware of the mathematical typesetting and semantics rules. This helps to accelerate application development in computer-aided education, computer algebra systems, authoring tools, and many other applications for mathematics, science, business, economics, etc. Author: Hermitech Laboratory| Date: 16-09-2006 | Size: 3060 KB
