Efficient XML Path Filtering Using GPUs
"... Publish-subscribe (pub-sub) systems present the state of the art in information dissemination to multiple users.Current XML-based pub-sub systems provide users with considerable flexibility allowing the formulation of complex queries on the content as well as the structure of the streaming messages. ..."

. Messages that contain one or more matches for a given user profile (query) are forwarded to the user. Recently various approaches focused on accelerating XML path query filtering using dedicated hardware architectures, like FPGAs. Despite their very high throughput, FPGAs require extensive update time
Efficient Filtering of XML Documents for Selective Dissemination of Information
, 2000
"... Information Dissemination applications are gaining increasing popularity due to dramatic improvements in communications bandwidth and ubiquity. The sheer volume of data available necessitates the use of selective approaches to dissemination in order to avoid overwhelming users with unnecessaryi ..."

sophisticated filtering mechanisms that take structure information into account. We have developed several index organizations and search algorithms for performing efficient filtering of XML documents for large-scale information dissemination systems. In this paper we describe these techniques and examine
Tor: The secondgeneration onion router,”
- in 13th USENIX Security Symposium. Usenix,
, 2004
"... Abstract We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, an ..."

in the circuit and force them to decrypt it. Rather than using a single multiply encrypted data structure (an onion) to lay each circuit, Tor now uses an incremental or telescoping path-building design, where the initiator negotiates session keys with each successive hop in the circuit. Once these keys
Efficient filtering of XML documents with XPath expressions
, 2002
"... cychan,pascal,minos,rastogi¡ We propose a novel index structure, termed XTrie, that supports the efficient filtering of XML documents based on XPath expressions. Our XTrie index structure offers several novel features that make it especially attractive for largescale publish/subscribe systems. First ..."

names organized in a trie structure and using a sophisticated matching algorithm, XTrie is able to both reduce the number of unnecessary index probes as well as avoid redundant matchings, thereby providing extremely efficient filtering. Our experimental results over a wide range of XML document
Yfilter: Efficient and scalable filtering of XML documents
- In ICDE
, 2002
"... Soon, much of the data exchanged over the Internet will be encoded in XML, allowing for sophisticated filtering and content-based routing. We have built a filtering engine called YFilter, which filters streaming XML documents according to XQuery or XPath queries that involve both path expressions an ..."

Intelligent Scissors for Image Composition
- In Computer Graphics, SIGGRAPH Proceedings
, 1995
"... We present a new, interactive tool called Intelligent Scissors which we use for image segmentation and composition. Fully automated segmentation is an unsolved problem, while manual tracing is inaccurate and laboriously unacceptable. However, Intelligent Scissors allow objects within digital images ..."

, rather than simply the strongest edge in the neighborhood. Boundary cooling automatically freezes unchanging segments and automates input of additional seed points. Cooling also allows the user to be much more free with the gesture path, thereby increasing the efficiency and finesse with which boundaries
Efficient Static Analysis of XML Paths and Types
, 2008
"... We present an algorithm to solve XPath decision problems under regular tree type constraints and show its use to statically type-check XPath queries. To this end, we prove the decidability of a logic with converse for finite ordered trees whose time complexity is a simple exponential of the size of ..."
