This review presents a general theory of financial crashes and of stock market instabilities that his co-workers and the author have developed over the past seven years. We start by discussing the limitation of standard analyses for characterizing how crashes are special. The study of the frequency distribution of drawdowns, or runs of successive losses(More)
The need for uniied notation in atmospheric and oceanic data assimilation arises from the eld's rapid theoretical expansion and the desire to translate it into practical applications. Self-consistent notation is proposed that bridges sequential and variational methods, on the one hand, and operational usage, on the other. Over various other mottoes for this(More)
—We report on an active multiview system for real-time 3D reconstruction based on phase measuring triangulation. Our system overcomes one of the greatest drawbacks in active 3D reconstruction, namely occlusions due do shadowing of either the camera or the projector light source. Our system is comprised of two high speed cameras in conjunction with two(More)

We describe an active depth imaging system based on phase measuring triangulation. Typically depth-maps generated with such 3D scanning systems suffer from occlusions and imperfections, especially in the vicinity of depth discontinu-ities. Applying multiple color images, captured with a camera array, for view synthesis from the erroneous depth-maps can(More)
We report on a fast algorithm for the generation of cylindrical panoramic views from hand-held video sequences. Due to its high processing speed the algorithm is suited for hardware implementation into next generation video-and photo cameras. This enables the user to easily create immersive views from simple pan shots of variable quality. The individual(More)
Validation is often defined as the process of determining the degree to which a model is an accurate representation of the real world from the perspective of its intended uses. Validation is crucial as industries and governments depend increasingly on predictions by computer models to justify their decisions. We propose to formulate the validation of a(More)
6a clearly shows the strong signal which the correlation algorithm computes to identify the region where the commanded and reference velocities differ. Figure 6b shows how the reference velocity closely tracks the commanded velocity when the force feedback is negligible (Figure 6c). Note that after the connector disengages, the guarded move SMP interprets(More)
