Maple T.A. 6

Maple T.A. 6Maplesoft is proud to announce the latest release of our testing and assessment tool, Maple T.A.™ 6!

Maple T.A. 6 enables significant levels of integration with course management systems, as well as internationalization tools and increased performance, offering a smooth, streamlined experience for instructors and students working in these environments. Maple T.A. is an easy-to-use web-based system for creating tests and assignments, and automatically assessing student responses and performance.

The new product includes a connector to Moodle™, a popular open-source course management system, which lets users access Maple T.A. directly from their Moodle courses. A new web services application programming interface (API) provides tools to allow an institution to integrate Maple T.A. with virtually any course management system, including custom-built solutions. In addition, the Maple T.A. Connector for Blackboard® Software has been updated to work with Maple T.A.6.

Maple T.A. 6, in addition to international language support for question content available in earlier versions, now provides a translatable interface so that menus, messages, help, and other text seen by instructors and students can appear in the local language. No programming knowledge is required to create or configure the translation.

Maplesoft Opens Office in Germany

Maplesoft is happy to announce the opening of its first office in Germany. The move to localized sales and support in Germany underscores the importance of the German and Austrian market for Maplesoft. With the opening of this office, Scientific Computers will no longer act as Maplesoft’s reseller in Germany and Austria. Maplesoft is working closely with Scientific Computers to ensure a smooth transition for existing users.

The Maplesoft office in Germany is now open, and local representatives are available to support all new and existing customers. To contact the Maplesoft office in Germany, please call 49-241-980919-30 or email germany@maplesoft.com. Some members of Scientific Computers’ staff have become Maplesoft employees, so that customer relationships – both business and technical – will not be interrupted

MapleSim used in the develoment of a wind turbine system

Wind power generation represents one of the many important new green technologies that are being developed to address climate change in the 21st century. Learn how a customer in the energy sector uses MapleSim in a crucial phase of the development of a wind turbine power generation system.

Wind Turbine SystemThe challenge:
The customer needs to develop a predictive model of a wind turbine. The model will be used to develop control strategies that will maintain a steady, predictable power output despite the highly variable and unpredictable changes in wind conditions. The system needs to adapt quickly to changes in wind speed and direction by changing the direction of the nacelle (the pod that contains the power generation components) and the angle of attack of the propeller blades with respect to the wind direction and speed.

The solution:
A multi-domain model that incorporates mechanical, signal blocks, controllers, and electrical components was created in MapleSim. The mechanical portions include the generator tower, propeller, and nacelle. A positional controller on the nacelle was created to respond to previously measured wind speed/direction data provided in an Excel® spreadsheet. When a simulation was performed with varying wind conditions, it showed that the blade angle changed in response to changes in wind speed and direction, resulting in a relatively constant blade speed producing a near-constant power output of 300KW, as desired. Because the wind turbine model is fully parameterized, it can be easily updated for different configurations and operating conditions.

The Challenge of the Challenger Puzzle
Dr. Robert Lopez
I have always wondered about this puzzle - there are twelve numbers to be determined by some ten equations, and the condition that the numbers are integers between one and nine. To what extent will these conditions determine the solution to the puzzle?

Dr. Robert Lopez
The physics instructor who asked how to build such a tool had both solutions in his hands before the end of the day on which I received the question. It was a Friday afternoon, and when I got back on Monday morning, I found "words cannot say..." in my inbox, sent over the weekend, from Greece from whence the question came.

Application Center Highlights

Quadrocopter
Author: Maplesoft

The forces and torques in the Body subsystem are created by four rotors, each driven by a DC motor. The lift and drag of each rotor are computed from the angular speed. A controller subsystem is used to maintain the altitude of the quadrocopter at a reference of 50 m. A one second failure is simulated at the 20 second mark in order to create a perturbation, and as can be seen in the simulation, the model stabilizes shortly thereafter.

Maplesoft In The Press

Here are some highlights of this past month press coverage.

Scientific software goes parallel
Desktop Engineering , March 31, 2010

Extract: “’Our goal for the future is to keep expanding the set of operations where multi-processing happens automatically and without further user intervention, while always allowing an expert user to override the defaults and interact with Maple's parallel toolkits at a low level in order to achieve the best possible performance,’ said Laurent Bernardin, executive vice president of research and development at Maplesoft.”

Watchmaker uses mathematical software to lengthen running time of watches
Scientific Computing, March 16, 2010

Extract: “Maple makes it easy to identify the critical parameters related to the required function and the figures of merit of the system. It also helps to establish analytical macro models, which are useful elements for analysis and for developing new concepts.”
