Central Angles
This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)

Inscribed Angles
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)

Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc.

Lose Yourself in the Digits - Song
This music video is to the tune of Eminem's "Lose Yourself" and teaches about the concept of Pi.  Lyrics are not included on the screen but can be found at www.teachpi.org.  The lyrics in the chorus are, "You better lose yourself in the digits of pi.  It's a high but you got a thousand more to go.  The numbers do not stop or drop into pattern, no. To memorize it would take most of a lifetime." (04:26)

Redefining the Wall: Architecture, Materials and Macroelectronics
As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the ar

Regularity conditions for Banach function algebras
In June 2009 the Operator Algebras and Applications International Summer School was held in Lisbon. Dr Joel Feinstein taught one of the four courses available on Regularity conditions for Banach function algebras. He delivered four 90 minute lectures on and this learning object contains the slides, handouts, annotated slides and audio podcasts from each session. Banach function algebras are complete normed algebras of bounded, continuous, complex-valued functions defined on topological spaces.

Exploraci?n de relaciones entre analog?as y bocetos durante la generaci?n de ideas en dise?o industr
An exploration on the analogy-based idea generation process in industrial design is reported. In particular we try to identify relationships between the sketching process and the analogy building in order to elicit requirements for a supporting software. We use concurrent think aloud protocols to obtain experimental data and an extension of a proved content oriented schema to analyze them. Statistical analysis on segments containing .analogical chains. found relations between analogical and desi

The major themes of this course are estimation and control of dynamic systems. Preliminary topics begin with reviews of probability and random variables. Next, classical and state-space descriptions of random processes and their propagation through linear systems are introduced, followed by frequency domain design of filters and compensators. From there, the Kalman filter is employed to estimate the states of dynamic systems. Concluding topics include conditions for stability of the filter equat

Diversity and compounding for enhanced discrimination of breast masses in ultrasonic B-scan images
Ultrasonic tissue characterization aims at improving the ability of ultrasound to classify benign and malignant masses. The akagami distribution was recently proposed to model the statistics of the envelope of the backscattered echo from tissue. Its parameters demonstrated an ability to discriminate benign and malignant masses in breast tissue. However, there is a need to improve the performance of the parameters to reach clinically acceptable standards and also to eliminate any influence of var
