Ypsilon Scheme is a free software implementation of the R6RS standard of Scheme. It implements mostly concurrent garbage collection, which is optimized for multi-core CPU systems. Its author, Yoshikatsu Fujita, developed the Ypsilon implementation to satisfy the need for a real-time Scheme implementation suitable for computer game development without giving up a garbage collected dynamic interpreter.
Ypsilon is a cable-stayed bridge over Drammenselva in Drammen, Norway.
The pedestrian bridge connects Kunnskapsparken, the science park of Grønland in Drammen with the city park on Bragernes. The bridge was designed by the firm of Arne Eggen Architects. The three-way bridge has been given the name " Ypsilon" due to its special form – from the air it looks like a Y, with one abutment on the Strømsø side and two at the Bragernes side. The project was co-funded by the municipality of Drammen and Kunnskapsparken AS. Kunnskapsparken accommodates the libraries of the Buskerud University College, the public library of Drammen, and the Buskerud Regional Library.
