Earth Alerts v2019.1.70
Earth Alerts v2019.1.70 What is EARTH ALERTS? Earth Alerts is an application designed to run on Microsoft Windows that allows you to monitor in near real-time a variety of natural hazard events that are occurring anywhere around the world. Alert notifications, reports, and imagery provide the user with a convenient way to view natural phenomenon as they occur, whether close to home or some far-flung corner of the globe! Earth Alerts uses a variety of online resources provided by organizations such as the National Weather Service, U.S. Geological Survey and Smithsonian Institution (just to name a few), to identify what sort of activities "Mother Earth" is currently dishing out on the planet. To use Earth Alerts, you simply select the specific natural hazards -- earthquakes, tsunamis, volcanoes, tropical cyclones, wildfires, landslides, severe weather, local weather, etc. -- and the locations that interest you. The application will then automatically retrieve the latest information from various live data feeds available on the Internet and present it to you in a convenient arrangement of reports, maps and images. Earth Alerts has been available to the general public since 2005. In that time it has undergone a number of significant enhancements. As a hobby, a one man production and a labor of love, conceiving the ideas and creating Earth Alerts has been a (time consuming) pet project over the past few years! Much More than a weather monitoring program Earth Alerts includes basic weather tracking features such as National Weather Service alerts, current conditions, local forecasts and radar/satellite imagery. Note that this program does not provide the most extensive weather data or "fanciest" weather related imagery compared to what is available online. If weather information is all you're interested in, then Earth Alerts is probably NOT for you. There are many comprehensive applications, web browser add-ins, and websites available for ...

Model Air Design v1.9
Model Air Design v1.9 Model Air Design is the new, quick and easy way to create airplane models. It's a modern software tool for model aircraft design. Model Air Design is for every person, young or old, who has a desire to design and create airplane models but have found Computer Aided Design (CAD) software too difficult and time-consuming to learn. Model Air Design software develops CAD software skills. This app is a nice introduction to CAD software concepts. It shows you some of the cool stuff you can do with CAD software to design a model airplane. With Model Air Design you create a computer model aircraft from a group of airplane parts. Instead of drawing carefully every detail of the aircraft, you just choose from a selection of pre-drawn parts. Model Air Design will assemble and draw the aircraft from the parts you select. In addition, you will be able to modify and position the airplane parts in anyway that you like. For example, you can modify a wing in length, width or height, and you can position it higher, lower, forward or back. We have developed a method for you to design computer models, in 3D format, without the complexity of 3D CAD software. It is so easy and intuitive to use that you will have no difficulty learning to create with it. You will be designing airplane models in a matter of minutes. Model aircraft design software made easy. With Model Air Design you can be as creative as you want. Substiture parts from other airplanes. Move them around, make them bigger or smaller. You can even paint the aircraft with your favorite colors. Here are some examples of what you can do: Visualization is the primary objective. Model Air Design makes it possible to visualize your aircraft design ideas. ...

NASA’s Eyes 1.0
NASA’s Eyes 1.0 Experience Earth and our solar system, the universe and the spacecraft exploring them, with immersive apps. The Cassini mission launched in 1997 and spent seven years traveling to Saturn, arriving in 2004. Cassini is the first spacecraft to orbit Saturn, and has provided a treasure trove of data and images of the entire Saturnian system. Now you can ride onboard the spacecraft throughout the entire mission (20 years) using “Eyes on Cassini” on your Mac or PC. In this interactive visualization, you can ride along with the Cassini spacecraft at any time during the entire mission, a period of 20 years! For example, watch the arrival at Saturn on July 1st, 2004, or see Cassini launch the Huygens probe and follow it to Titan, the largest moon of Saturn. You can see where Cassini was when it captured iconic images, and you can compare the real images to the visualization. You can even ride along with Cassini during its final 20 orbits, in which it zips between Saturn and its rings -- a place no spacecraft has explored before. And you can watch these things happen at actual speed, or much, much faster. All of this and more is waiting to be explored. Humanity’s farthest and longest-lived spacecraft, Voyager 1 and 2, achieve 40 years of operation and exploration this August and September. Despite their vast distance, they continue to communicate with NASA daily, still probing the final frontier. Their story has not only impacted generations of current and future scientists and engineers, but also Earth’s culture, including film, art and music. Each spacecraft carries a Golden Record of Earth sounds, pictures and messages. Since the spacecraft could last billions of years, these circular time capsules could one day be the only traces of human civilization. In this interactive visualization, you ...

Prime95 29.4 32bit
Prime95 29.4 32bit Prime95 is a small and easy to use application that allows you to find Mersenne Prime numbers. Mersenne numbers can be proved composite (not prime) by either finding a factor or by running a Lucas-Lehmer primality test. Prime numbers have long fascinated amateur and professional mathematicians. An integer greater than one is called a prime number if its only divisors are one and itself. The first prime numbers are 2, 3, 5, 7, 11, etc. For example, the number 10 is not prime because it is divisible by 2 and 5. A Mersenne prime is a prime of the form 2P-1. The first Mersenne primes are 3, 7, 31, 127, etc. There are only 40 known Mersenne primes. There are two ways to use this program. The automatic way uses a central server, which we call the PrimeNet server, to get work to do and report your results. Anyone with Internet access, including AOL, CompuServe, and dial-up ISP users should use this method. You do not need a permanent connection to the Internet. The second method is the manual method. It requires a little more work and monitoring. Recommended for computers with no Internet access or with some kind of firewall problem that prevents the automatic method from working. New features in Version 29.4 of prime95.exe ------------------------------------------- 1) GIMPS has a new sub-project -- finding (probable) prime Mersenne cofactors. This sub-project has two parts: 1) Running PRP tests, and 2) Finding additional factors. To support this new sub-project there are three new work preferences: PRP on Mersenne cofactors, PRP double-checking on Mersenne cofactors, ECM on Mersenne cofactors. 2) Like LL tests, PRP tests now support shift counts to aid in running double-checks. Shift counts are only ...

RASAero II 1.0.1.0
RASAero II 1.0.1.0 RASAero II is a combined aerodynamic analysis and flight simulation software package for model rockets and high power rockets, amateur rockets, and sounding rockets. RASAero II can also be used for predicting aerodynamic coefficients for use in other flight simulation programs for orbital rockets. The RASAero II aerodynamic prediction methods are the most accurate available for model, high power, and amateur rockets, and are of equivalent accuracy to professional engineering method aerodynamic analysis codes used for missiles, sounding rockets, and space launch vehicles. In testing in comparison with high power rocket barometric altimeter data, optical tracking data, accelerometer-based flight data, and GPS flight data, the average RASAero II altitude prediction error was 3.38%, with 78.8% of the RASAero II flight simulation altitude predictions within +/- 10% of the flight data, and 42.4% of the altitude predictions within +/- 5% of the flight data. The RASAero II aerodynamic predictions include drag coefficient at zero degrees angle of attack, drag coefficient with a non-zero angle of attack, and lift coefficient and normal force coefficient with angle of attack; for both power-on (thrust phase) and power-off (coast phase). Center of pressure is predicted both as a function of Mach number and as a function of angle of attack. Aerodynamic coefficients are predicted for the subsonic, transonic, supersonic, and hypersonic flight regimes, from Mach 0.01 to Mach 25. The RASAero II aerodynamic prediction methods and the RASAero II software have been calibrated against NACA and NASA wind tunnel model data, free-flight model data and sounding rocket data, missile aerodynamic data, and professional engineering method missile aerodynamic analysis programs, against which in comparison tests RASAero II has demonstrated equivalent numerical accuracy.
