http://www.maplesoft.com/applications/view.aspx?SID=153536&ref=Feed
<p>You run a pan-US drone delivery service for a popular online retailer. You're given a list of zip codes across the US at which you need to drop off parcels, and want to optimize its journey so it travels the shortest distance.</p>
<p>This application extracts the latitude and longitude of those zip codes from an SQLlite database (the application includes the database, which cross-references US zip codes against their latitude, longitude, city and state). The application then performs a traveling salesman optimization and plots the shortest path on a map of the US.</p>
<p>This application uses background plot images, and SQLLite integration, two new features introduced in Maple 18.</p><img src="/view.aspx?si=153536/pan-us_drone.jpg" alt="Optimize the Flight Path of a Pan-US Delivery Drone" align="left"/><p>You run a pan-US drone delivery service for a popular online retailer.

http://www.maplesoft.com/applications/view.aspx?SID=153537&ref=Feed
<p>This application is a simple demonstration of Maple 18's new HTTP package for communicating with web-based APIs. It has a component-based interface that lets you interact with Google Maps. Simply enter a latitude and longitude, and set your zoom level and desired map type. Maple will then:</p>
<ul>
<li>download map images using the Google Maps API, </li>
<li>and then place those images on a label component</li>
</ul>
<p>The code for the application is located in the Startup code region (Edit > Startup Code).</p>
<p>The Google Maps API limits the number of anonymous queries you can make per day. If you exceed their limit, you'll need to include a Google Maps API key in the startup code.</p>
<p>The default latitude and longitude point to the location of the Maplesoft office in Waterloo, Ontario.</p><img src="/view.aspx?si=153537/Maps_image1.jpg" alt="Interactive Google Maps Component" align="left"/><p>This application is a simple demonstration of Maple 18's new HTTP package for communicating with web-based APIs.

http://www.maplesoft.com/applications/view.aspx?SID=153516&ref=Feed
<p>The application presents and definition, creation and handling of jump-diffusion processes. In general, jump-diffusion is an extension to the theory of stochastic processes where the underlying parameters exhibit shocks and "jump" to their new values. Stochasticity with jumps is well recognised in several scientific branches including physics, chemistry, biology, but also economic and finance. The application looks at the example of the last-mentioned fields where the theory of jump-diffusions has been particularly actively researched and applied.</p><img src="/view.aspx?si=153516/Jump_image1.jpg" alt="Jump-diffusion stochastic processes with Maple" align="left"/><p>The application presents and definition, creation and handling of jump-diffusion processes.

http://www.maplesoft.com/applications/view.aspx?SID=153490&ref=Feed
<p>This application analyzes a vapor compression refrigeration cycle for the refrigerant R134a. The application calculates heat changes over the compressor, condenser, throttle and evaporator, together with the coefficient of performance. Additionally, a P-h-T chart illustrating the refrigeration cycle is plotted.</p>
<p>Thermophysical properties are provided by the open source C++ CoolProp library (<a href="http://coolprop.org/">http://coolprop.org</a>). Once compiled and linked to Maple, CoolProp lets you access the properties of pure fluids, pseudo-pure fluids, and humid air with a function call. This application comes with a CoolProp DLL for 64-bit Windows. You may need to compile CoolProp for your own environment for a compatible library. </p><img src="/view.aspx?si=153490/CoolProp_image1.jpg" alt="Analysis of a Refrigeration Cycle with CoolProp" align="left"/><p>This application analyzes a vapor compression refrigeration cycle for the refrigerant R134a.

<p>This suspension design tool provides a complete toolbox for design and analyses of the automobile's suspension systems. As the most popular suspension systems layout, the front and rear systems are supposed to be Macpherson and torsion beam respectively. The toolbox can perform complete kinematic analyses of the front and rear suspensions and the results can be viewed using a wide variety of characteristic curves, such as spring deflection, damper deflection, camber by roll, scrub by bump, roll centre position and others. Moreover, it can size the front and rear springs, dampers and anti-roll-bars . In this application, the input parameters can be easily changed, new simulations computed, and plots selected through the use of buttons, drop-down lists, and other interactive elements.</p><img src="/view.aspx?si=153486/Suspension_image1.jpg" alt="Suspension Design" align="left"/><p>This suspension design tool provides a complete toolbox for design and analyses of the automobile's suspension systems.

http://www.maplesoft.com/applications/view.aspx?SID=151351&ref=Feed
<p>Abstract<br /><br />The main purpose of this article is to show how to use Hohmann elliptic transfer in two situations:<br />a- When one manned spaceship is trying to catch up with an other one <br />on the same circular orbit around Earth.<br />b- When delivering a payload from Earth to a space station on a circular <br />orbit around Earth using 2-stage rocket .<br /><br />The way we set up the problem is as follows:<br />Consider two manned spaceships with astronauts Sally & Igor , the latter<br />lagging behind Sally by a given angle = 4.5 degrees while both are on the same<br />circular orbit C2 about Earth. A 2d lower circular orbit C1 is given. <br />Find the Hohmann elliptic orbit that is tangent to both orbits which allows<br />Sally to maneuver on C1 then to get back to the circular orbit C2 alongside Igor.<br /><br />Though the math was correct , however the final result we found was not !! <br />It was somehow tricky to find the culprit!<br />We have to restate the problem to get the correct answer. <br />The animation was then set up using the correct data. <br />The animation is a good teaching help for two reasons:<br />1- it gives a 'hand on' experience for anyone who wants to fully understand it,<br />2- it is a good lesson in Maple programming with many loops of the type 'if..then'.<br /><br />Warning<br /><br />This particular animation is a hog for the CPU memory since data accumulated <br />for plotting reached 20 MB! This is the size of this article when animation is <br />executed. For this reason and to be able to upload it I left the animation <br />procedure non executed which drops the size of the article to 300KB.<br /><br />Conclusion<br /><br />If I can get someone interested in the subject of this article in such away that he or <br />she would seek further information for learning from other sources, my efforts<br />would be well rewarded.</p><img src="/view.aspx?si=151351/Elliptic_image1.jpg" alt="Hohmann Elliptic Transfer Orbit with Animation" align="left"/><p>Abstract<br /><br />The main purpose of this article is to show how to use Hohmann elliptic transfer in two situations:<br />a- When one manned spaceship is trying to catch up with an other one <br />on the same circular orbit around Earth.<br />b- When delivering a payload from Earth to a space station on a circular <br />orbit around Earth using 2-stage rocket .<br /><br />The way we set up the problem is as follows:<br />Consider two manned spaceships with astronauts Sally & Igor , the latter<br />lagging behind Sally by a given angle = 4.5 degrees while both are on the same<br />circular orbit C2 about Earth.

Thus, the computer methods analysis, as well as refinement and compression, are very helpful as for the problems of recognition and detection of their key diagnostic features.
