ÐTime Warp is an optimistic protocol for synchronizing parallel discrete event simulations. To achieve performance in a multiuser network of workstation (NOW) environment, Time Warp must continue to operate efficiently in the presence of external workloads caused by other users, processor heterogeneity, and irregular internal workloads caused by the simulation model. However, these performance ...

It has been pointed out (e.g., by Richard Fujimoto) that protocols developed for the difficult problem of parallel and distributed simulation can also be adapted to other distributed applications. Indeed, in the mid 1980’s David Jefferson adapted his Time Warp protocol to the problem of database concurrency control. In the present work, we consider our own variants of the Time Warp for database...

To reduce inter-speaker variability, vocal tract length normalization (VTLN) is commonly used to transform acoustic features for automatic speech recognition (ASR). The warp factors used in this process are usually derived by maximum likelihood (ML) estimation, involving an exhaustive search over possible values. We describe an alternative approach: exploit the correlation between a speaker’s a...

We describe the design and preliminary analysis of an optimization technique for XPath called warp-edge optimization. The XPath data model is a tree-like data model that has an edge from an element to each component in the content of that element. The edges are traversed in the evaluation of an XPath expression. A warp edge is an edge that is something other than a parent to child edge, i.e., a...

Automatic iterative model (re-)building, as implemented in ARP/wARP and its new control system flex-wARP, is particularly well suited to follow structure solution by molecular replacement. More than 100 molecular-replacement solutions automatically solved by the BALBES software were submitted to three standard protocols in flex-wARP and the results were compared with final models from the PDB. ...

ion speeds up the DTW algorithm by operating on a reduced representation of the data. These algorithms include IDDTW [3], PDTW [13], and COW [2] . The left side of Figure 5 shows a full-resolution cost matrix for which a minimum-distance warp path must be found. Rather than running DTW on the full resolution (1/1) cost matrix, the time series are reduced in size to make the number of cells in t...

After presenting string-like solutions with a warp factor to Einstein’s equations, we study localization of various spin fields on a string-like defect in a general space-time dimension from the viewpoint of field theory. It is shown that spin 0 and 2 fields are localized on a defect with the exponentially decreasing warp factor. Spin 1 field can be also localized on a defect with the exponenti...

Vocal tract length normalisation (VTLN) is a commonly used speaker normalisation approach. It is attractive compared to many normalisation schemes as it is typically dependent on only a single parameter, allowing the warp factors to be robustly calculated on little data. However, the scheme normally requires explicitly coding the data at multiple warp factors. Furthermore, it is only possible t...
