Maple Helps Teach Calculus to 11Year Old Students
For years, educators have been debating that use of technology in the classroom could radically change not just how we teach our children, but what we teach them, and when. The University of Tasmania in Australia set out to prove it. Because of their commitment to embracing the Digital Education Revolution, and to showcasing how big a transformation the use of computers can make in students’ learning, the University decided to take on the challenge of teaching integral calculus to 11yearolds. While this age group is traditionally considered far too young for this topic, which is usually introduced at age 17 at the very earliest, the University wanted to see if computer software would make a difference in their learning. If students become comfortable with this complex topic at a young age, perhaps learning could become easier and more of them will gravitate to the scientific and technical fields as they get older.
The researchers used Maple as the software of choice for this project. They used Maple to teach fifth graders the Calculus curriculum used in the first year engineering program in Australian universities. The project team trained five classroom teachers who then worked with their students for two hours a week for six weeks. During this time, the students were introduced to a series of realworld problems and mathematical concepts, and learned how to solve these problems in Maple. Students used Maple to set up the solutions to word problems, calculate results, and graph functions.

MathematicsBased Modeling of a SeriesHybrid Electric Vehicle
Thursday, September 27th at 10:00 am EDT
The automotive industry is in transformation. The complexity of the automobile has increased exponentially in the past decades and has triggered a design revolution that stresses detailed modeling and simulation steps prior to committing to metal and plastic. With new generation vehicles deploying hybrid (HEV), fully electric (EV), and fuel cell powerplants, the need for advanced physical modeling solutions is considerably greater due to increasing system complexity. This webcast covers new approaches to modeling and simulation for HEV and EV vehicle applications with emphasis on the development of highfidelity physical models of automotive batteries. To speed up the design and prototyping processes of HEVs, a method that automatically generates mathematics equations governing the vehicle system response in an optimized symbolic form is desirable. To achieve this goal, the physical modeling tool MapleSim was employed to develop the multidomain model of a seriesHEV, using the symbolic computing algorithms of the Maple software package to generate an optimized set of governing equations. The HEV model consists of a mean value internalcombustion engine, a Liion battery pack, and a multibody vehicle model. Simulations are then used to demonstrate the performance of the HEV system. Simulation results show that the model is viable and the number of governing equations is reduced significantly, resulting in a computationally efficient system. Webcast attendees will be invited to interact with the speakers during the program's live Q&A segment.

Symbolic Computation Techniques for Multibody Model Development and Code Generation
Multibody models can generate large systems of differential algebraic equations (DAEs). These equations can take a significant amount of time to solve numerically and often the modeller needs to make difficult decisions between model fidelity and simulation speed.
This webinar presents some of the benefits of a general purpose symbolic computation environment when constructing and generating simulation code for multibody, multidomain systems. Specifically, it considers how tools provided by these environments can be harnessed to generate highly efficient simulation code through coordinate selection, symbolic manipulation, and expression optimization.

Space Equipment Gets in the Loop  MapleSim breaks new ground in HIL realtime simulation for planetary rovers
Desktop Engineering, August 7, 2012
“Dr. Amir Khajepour, Canada Research Chair in Mechatronic Vehicle Systems and a professor of engineering in the Mechanical and Mechatronics Engineering department at the University of Waterloo (UW), and his team worked with the Canadian Space Agency (CSA) and Maplesoft, to develop a hardwareintheloop (HIL) test platform for solarpowered planetary rovers... the main advantage of their approach is that it significantly reduces the overall development time in the project.” 

Transmission modeling and simulation: key to reducing power loss
Automotive Engineering Online, July 18, 2012
“Over the last decade there has been a remarkable push toward acausal modeling environments, such as MapleSim from Maplesoft, which takes a different approach to modeling. Rather than representing mathematics directly, models use components that contain governing equations, and it is incumbent on the solver to perform the mathematical manipulation.” 

Battery Design is Charging Ahead
Desktop Engineering, July 2, 2012
“...the industry is turning increasingly to mathbased modeling techniques that allow engineers to accurately describe the behavior of the systemand the constraints on the systemin physical terms. These model equations are then used to develop, test and refine designs quickly, without building physical prototypes. Hence, having a good virtual model of the battery is essential so that both battery behavior and the physical interaction of the battery with all the other components are properly reflected in the model.”
