Bath University Case Study, Cleveland Golf Case Study, NASA Tech Webinar Recording

Newsletter for July 2010

Bath University

Maple is being used at Bath University to provide a framework for the teaching of complex mathematics problem solving and for students to complete course work and assessment.

Maple allows the exploration and visualization of mathematical problems whilst enabling students to gain an insight into the theory and problem solving technique.  At Bath University the package is used in algebraic mathematics courses, with students using the system to complete most of the coursework.

“In our course, Maple is used as the vehicle in which students do their coursework and provide examination answers,” says Professor John Davenport, of the computer science department at the University of Bath. Maple is used on four challenging problems, representing 25 per cent of coursework marks (versus 75 per cent of examination marks).

Maple has become an important tool in the teaching of not only problem solutions but also the evaluation of the way algebra works. “For mathematicians it is not necessarily the problem but how to express the answer that requires application,” concedes Professor Davenport. “The teaching of these concepts is made so much easier by Maple and encourages students to look beyond the basic problems.”

MapleSim Helps Improve Your Golf Game

In the world of golf, players are always looking for ways to improve their game, and equipment manufacturers are always looking for ways to give their customers an edge. Cleveland Golf, an internationally recognized maker of golf clubs with a strong tradition of innovation, wanted to explore ways to increase the performance of their drivers. Their engineers turned to MapleSim, a physical modeling and simulation tool from Maplesoft, to help them in this project.

In particular, they wanted to investigate the effect of different shafts on the performance of the driver. The flexibility of the shaft, and how the bending and torsion varies down the length of the shaft, plays a vital role in determining how far the golf ball will travel. The engineers were looking for a good, efficient model which would allow them to explore the effects of different shaft designs on club performance.

With the help of Dr. John McPhee, NSERC Industrial Research Chair and professor of Systems Design Engineering at the University of Waterloo, they used MapleSim to create a model of a driver.

Cleveland Golf was impressed with both the accuracy of the model and the flexibility and performance MapleSim gave them. “The MapleSim models we're running allow us to predict head delivery conditions with more variables, higher precision, and faster run times”, said John Rae, Research Manager, R&D, of Cleveland Golf. “Using MapleSim's simulation tools we can generate custom swing calculations based on every equipment variable, leaving nothing to speculation.”

Recording of Webinar with NASA Tech now available: Advanced Physical Modeling Techniques Accelerate the Design of Complex Space Systems

Thank you to everyone who attended our webinar with the NASA Tech on June 23rd. A recording is now available here.

This webinar presents an overview of modeling and simulation of space systems using physical modeling techniques derived from symbolic model formulation techniques.

To illustrate these techniques, this webinar presents the details of a recent initiative launched at the University of Waterloo (UW). For unmanned planetary exploration to be successful, advanced autonomous robotic rovers are needed.

Dr. Amir Khajepour, Canada Research Chair in Mechatronic Vehicle Systems and Professor of Engineering in the Mechanical and Mechatronics Engineering department at UW, is working with the Canadian Space Agency (CSA), Maplesoft, and the Government of Canada, to develop a full solution for the power management system of autonomous rovers. This new initiative uses the latest generation of symbolic modeling technology (e.g. MapleSim from Maplesoft) to rapidly develop high fidelity, multi-domain models of the rover subsystems.

The Traveling Salesman's U.S. Roadtrip
Samir Khan
I spend much of my time traveling for business. These trips often last a week, and we try to visit as many potential customers as possible, and in the most efficient order. This involves matching our hosts' calendars with our own, booking the most cost effective travel options, and coping with last-minute cancellations and changes. It isn’t easy! Read More>>
Lines - The Devil Is in the Details
Dr. Robert Lopez
Points and lines, and the relationships between them, are essential ingredients of so many problems in, for example, calculus. In particular, obtaining the equation of the perpendicular bisector of a line segment, dropping a perpendicular from a point to a given line, and calculating the distance from a point to a line are three tasks treated in elementary analytic geometry that recur in the applications. Let's explore the tools that Maple has for implementing these basic calculations. Read More>>
Drawing Solids of Revolution

From Months to Days
Dr. Tom Lee
The term “from months to days” is a favorite slogan of mine and I have relied on it religiously for over two decades to illustrate the fundamental benefit of symbolic computation. Whether it’s the efficient development of complex physical models using MapleSim, or exploration of parametric design surface equations (my dissertation) using good old fashioned Maple V Release 2, the punch that symbolic computation provided was to automate the algebraic mechanics of equation development.

Tips & Techniques

Classroom Tips and Techniques: Visualizing Regions of Integration
Author: Dr. Robert Lopez

Five of the new task templates in Maple 14 are designed to help visualize regions of integration for iterated integrals. In particular, there are task templates for double integrals in Cartesian and polar coordinates, and for triple integrals in Cartesian, cylindrical, and spherical coordinates. These task templates can be found at the end of the path

Tools > Tasks > Browse: Calculus - Multivariate > Integration > Visualizing Regions of Integration

Each of these task templates provides for iterating the relevant multiple integral in any of its possible orders. An example for each task template is provided.

Visit Tips & Techniques on the Maplesoft website for more applications.

The Astroid and Its Tangent Lines
Author: Dr. Robert Lopez

Tangents to the astroid have fixed length if restricted to a single quadrant. In fact, the envelope of a line of fixed length that has its endpoints on the coordinate axes in the first quadrant is just the astroid.

Maplesoft In The Press

Here are some highlights of this past month press coverage.

Modeling Autonomous Space Robots
Product Design & Development, July 6, 2010

Extract: In order to support the ongoing focus for unmanned planetary exploration, advanced autonomous robot rovers need to be developed. To develop solutions for the power management systems in these robots, one scientist has partnered with the Canadian Space Agency (CSA), Canadian government, and software tools provider Maplesoft to symbolically model a solution. Using MapleSim, a program with symbolic modeling technology, Dr. Amir Khajepour, Canada Research Chair in Mechatronic Vehicle Systems and Professor of Engineering in the Mechanical and Mechatronics Engineering department at the University of Waterloo (UW), will tackle the project.

Maple 14 and MapleSim 4
Scientific Computing World, June 16, 2010

Extract: "Upgrades to Maplesoft's flagship computer algebra package Maple and high profile simulation sibling MapleSim have now firmly established an annual pattern of linked release, with versions 14 and 4 respectively having recently appeared. Since MapleSim draws its power from Maple, it therefore makes sense to make a shift from past practice and review them together."
MapleSim: Fast and Furious Progress from Maplesoft
Scientific Computing , June 5, 2010

Extract: “Attention Engineers! The developers at Maplesoft rarely sit still for very long. There is usually a 12- to 18-month lag in new software versions, but with this program I see a major new product far more often (or so it seems!)...By allowing the user to ‘lift the hood’ and see all of the underlying mathematics for each section of the model, MapleSim 3 takes the black-box haze out of the process and further simplifies understanding of the physical model. By employing the same development philosophy as is found in Maple, i.e., make it as simple as possible to use, the folks at Maplesoft have delivered yet another very valuable tool.”
