Produce effects without effects

submitted by: jllebrun

As the number of effects increases, custom animations rapidly become unwieldy. An alternative technique consists in using one slide per effect, thus simplifying the process. The addition of slide transitions ensures that entrance or exit effects are maintained. The drawbacks of creating effects without effects - a large number of slides- are compensated by two key advantages: simplicity, and direct access to any part of a slide composed of many effects, not just its beginning.

2008 Tawani Antarcitc Expedition Video

submitted by: Edeker
In November 2008, an international team of distinguished scientists, educators and explorers embarked on a six week expedition to Antarctica. Their primary mission was to study the icy ecosystems of the Schirmacher Oasis and the perennially ice-covered Lake Untersee. In this exceptionally hostile environment, the team hoped to find a new species of "extremophile" - a hardy life form that exists and flourishes in conditions inhospitable to most known organisms. These discoveries could...

Robotic Mouse Makes Maze Debut at UC San Diego

submitted by: ucsandiego
An intrepid group of University of California, San Diego undergraduates has designed and build a robotic mouse from scratch. The electrical engineering and computer science undergraduates from the Jacobs School of Engineering also wrote the software to teach the robot to solve a maze. The team unveiled their mouse at the IEEE Region 6 Southwest Area Spring Meeting on Saturday, April 25th, held at UC San Diego.

Optimal periodic disturbance reduction for active noise cancelation

submitted by: callafon
The design of an optimal internal model-based (IMB) controller by extending standard discrete time optimal control theory for IMB controllers is described. The optimal observer and state feedback gains of the IMB controller are given via the solution of discrete time algebraic Riccati equations. The design method is applied to an acoustic system that is subjected to disturbances from a server fan. Periodic disturbances from the server fan appear as harmonics of the fundamental frequency of...
