Circuit Board Simulator

Material type: Simulation

Year: 2000

Authored by:

George Watson, Becky Kinney

Description

circuit.fwThis simulation allows students to build a virtual circuit using resistors and batteries from the file drawers. Users can also measure resistance, voltage and current by clicking on any element within the completed circuit. A great way to explore.

Binomial Distribution

Material type: Simulation

Year: 2000

Authored by:

Becky Kinney

Description

Marble Game thumbnailMarbles bounce down an array of pegs. The resulting binomial distribution is displayed graphically in real time. A control panel allows the size of the array, and the probability of a bounce to the right to be varied.

A short introduction has been added in the form of a series of multiple choice questions with instructions.

New Methods in the Cleaning of Paintings

Material type: Video lectures

Year: 1991

Used in courses: Undefined

Authored by: Richard Wolbers

Department or Unit: Art Conservation

Description

Richard Wolbers

Richard C. Wolbers is a pioneer in the development of new methods of cleaning painted surfaces. His research on enzymes, soaps and resins has been the basis for developing new techniques using water and waterborne materials to address cleaning problems.

This video course was originally recorded in 1991. The series includes 15 hours of lectures on the underlying principles and processes of this scientific approach to cleaning paintings and painted surfaces. In addition, case studies are examined to illustrate how these techniques can be applied to specific cleaning problems.

List of contents

The course is divided into 9 sessions each with a different topic. Some sessions have approximately one hour of video, others have two hours.
