Oceanstore: An architecture for global-scale persistent storage
, 2000
"... OceanStore is a utility infrastructure designed to span the globe and provide continuous access to persistent information. Since this infrastructure is comprised of untrusted servers, data is protected through redundancy and cryptographic techniques. To improve performance, data is allowed to be cac ..."

to be cached anywhere, anytime. Additionally, monitoring of usage patterns allows adaptation to regional outages and denial of service attacks; monitoring also enhances performance through pro-active movement of data. A prototype implementation is currently under development. 1
Geography-informed Energy Conservation for Ad Hoc Routing
- ACM MOBICOM
, 2001
"... We introduce a geographical adaptive fidelity (GAF) algorithm that reduces energy consumption in ad hoc wireless networks. GAF conserves energy by identifying nodes that are equivalent from a routing perspective and then turning off unnecessary nodes, keeping a constant level of routing fidelity. GA ..."

. GAF moderates this policy using application- and system-level information; nodes that source or sink data remain on and intermediate nodes monitor and balance energy use. GAF is independent of the underlying ad hoc routing protocol; we simulate GAF over unmodified AODV and DSR. Analysis and simulation
DSR: The Dynamic Source Routing Protocol for Multi-Hop Wireless Ad Hoc Networks”, in Ad Hoc Networking, edited by Charles E.
- Perkins, Chapter
, 2001
"... Abstract The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. DSR allows the network to be completely self-organizing and self-configuring, without the need for any existing network ..."

We have evaluated the operation of DSR through detailed simulation on a variety of movement and communication patterns, and through implementation and significant
Fast subsequence matching in time-series databases
- PROCEEDINGS OF THE 1994 ACM SIGMOD INTERNATIONAL CONFERENCE ON MANAGEMENT OF DATA
, 1994
"... We present an efficient indexing method to locate 1-dimensional subsequences within a collection of sequences, such that the subsequences match a given (query) pattern within a specified tolerance. The idea is to map each data sequence into a small set of multidimensional rectangles in feature space ..."

Tracking multiple independent targets: Evidence for a parallel tracking mechanism
- Spatial Vision
, 1988
"... Abstract-There is considerable evidence that visual attention is concentrated at a single locus in the visual field, and that this locus can be moved independent of eye movements. Two studies are reported which suggest that, while certain aspects of attention require that locations\be scanned serial ..."

Exploiting Sink Mobility for Maximizing Sensor Networks Lifetime
- Proceedings of the 38th Annual Hawaii International Conference on System Sciences
, 2005
"... Abstract—This paper explores the idea of exploiting the mobil-ity of data collection points (sinks) for the purpose of increasing the lifetime of a wireless sensor network with energy-constrained nodes. We give a novel linear programming formulation for the joint problems of determining the movement ..."

than minimizing the energy consumption at the nodes. For wireless sensor networks with up to 256 nodes our model produces sink movement patterns and sojourn times leading to a network lifetime up to almost five times that obtained with a static sink. Simulation results are performed to determine
Phase relationship between hippocampal place units and the EEG theta rhythm. Hippocampus 3:317–330
, 1993
"... Many complex spike cells in the hippocampus of the freely moving rat have as their primary correlate the animal's location in an environment (place cells). In contrast, the hippocampal electroencephalograph theta pattern of rhythmical waves (7- 12 Hz) is better correlated with a class of moveme ..."

During movement through the place field, the complex spike cells often fire in a bursting pattern with an interburst frequency in the same range as the concurrent electroencephalograph theta. The present study examined the phase of the theta
Motor facilitation during action observation: A magnetic stimulation study
, 1995
"... 1. We stimulated the motor cortex of normal subjects (transcranial magnetic stimulation) while they I) observed an experimenter grasping 3D-objects, 2) looked at the same 3D-objects, 3) observed an experimenter tracing geometrical figures in the air with his arm, and 4) detected the dimming of a lig ..."

Radar Interferometry and its application to changes in the Earth’s surface

A Comparison of Dynamic Branch Predictors that use Two Levels of Branch History
- in Proceedings of the 20th Annual International Symposium on Computer Architecture
, 1993

Recent attention to speculative execution as a mechanism for increasing performance of single instruction streams has demanded substantially better branch prediction than what has been previously available. We [1, 2] and Pan, So, and Rahmeh [4] have both proposed variations of the same aggressive dy ..."
