Rocket Propulsion Analysis (RPA) is a tool for the performance prediction of rocket engines. By providing a few engine parameters such as combustion chamber pressure, used propellant components, and nozzle parameters, the program obtains chemical equilibrium composition of combustion products, determines its thermodynamic properties, and predicts the theoretical rocket performance. A robust, proven, and industry-accepted Gibbs free energy minimization approach is used to obtain the combustion composition. It can perform analysis of nozzle flows with shifting and frozen chemical equilibrium, optimization of propellant components mixture ratio for maximum specific impulse of bipropellant systems, altitude performance analysis, analysis of nozzle performance with respect to overexpansion and flow separation, throttled engine performance analysis, estimation of test (actual) nozzle performance, and nested analysis: stepping of up to four independent variables (component ratio, chamber pressure, nozzle inlet conditions, and nozzle exit conditions).
mediAvatar iPhone Ringtone Maker for Mac can help you make iPhone ringtones by converting various videos and audios to M4R ringtones. Supported input types include AVI, MPEG, WMV, FLV, DivX, MP4, H.264/AVC, AVCHD, MKV, MP3, WMA, WAV, RA, and M4A. It can clip music segments before transforming them to ringtones. It fully supports iPhone 3GS (iPhone OS 3.0).
STermPro is a powerful program for serial port monitoring and control with protocols. STermPro lets you control a serial device with parameters, not bytes. An auto-answer feature helps with debugging and emulating external devices. Sending and receiving us supported simultaneously on many serial ports. Mixed strings with hex characters can be sent. Clearly arranged messages can be analyzed using the unique serial port flow visualization method. Custom serial devices and baud rates are supported.
DXF Export Java is a Java library for exporting CAD entities, along with their properties, to stream or AutoCAD DXF files at high speed and with ease. Creating a new DXF file takes only one call of the exporter class, provided that user data has been prepared and loaded to the required fields beforehand. The library handles all major entities, including Arc, Bezier, Circle, Ellipse, Hatch Pattern, Line, Multi-line Text, Pixel, Polyline, Rectangle, and Text. It also supports layers, colors, line styles, and other important properties. Source code and working demos are included.
MOOS Project Viewer is a Microsoft Project viewer that can open any MS Project file type (.mpp, .mpt, .mpx, .xml) for any Microsoft Project version (2000, 2003, 2007, or 2010). Available views: WBS, Gantt chart, task sheet, resource sheet, resource usage, and tracking Gantt. You can zoom in/out, collapse/expand, show/hide, resize, etc. It has an easy to use interface, the ability to print any view, a wide Gantt chart timescale range (from minutes to years), the ability to show critical path, deadlines, and baselines in a Gantt chart, show/hide, arrange, and resize columns per view, and show colors on task bars in Gantt charts.
