Web access logs, usually stored in relational databases, are commonly used for various data mining and data analysis tasks. The tasks typically consist in searching the web access logs for event sequences that support a given sequential pattern. For large data volumes, this type of searching is extremely time consuming and is not well optimized by traditional indexing techniques. In this paper ...

Proper determination of bed boundaries in layered reservoirs is vital ‎for accurate petrophysical interpretation of conventional logs. In the ‎wellbore, logs continuously measure physical properties of reservoir ‎while the properties change stepwise. This continuous representation ‎of logs may lead to ignorance of some high potential reservoir zones. ‎The main reasons for continuous nature of l...

We present the BTLA (Base Tree Link Augmentation) multicast routing infrastructure for heterogeneous wireless/wireline networks. BTLA has two goals: (a) to reduce the latency and overhead of joins, leaves, and handoffs in regions that experience high group dynamics and mobility, and (b) to optimize the multicast tree for stable regions that do not experience frequent group dynamics. BTLA consis...

In addition to the invention of iterative decoded capacity-achieving channel coding schemes, namely, turbo codes in the early 1990’s and the rediscovery of low-density parity-check (LDPC) codes in the mid 1990’s, digital fountain codes and network coding are two recent breakthroughs in the coding community. They offer great promise for providing robust and efficient data transport through a lar...

Marine controlled source electromagnetic (CSEM) data have been utilized in the past decade during petroleum exploration of Barents Shelf, particularly for de-risking highly porous sandstone reservoirs Upper Triassic to Middle Jurassic Realgrunnen Subgroup. In this contribution we compare resistivity response from CSEM wireline logs both water- and hydrocarbon-bearing wells. We show that there i...
