Probabilistic Roadmaps for Path Planning in High-Dimensional Configuration Spaces

by Lydia Kavraki, Petr Svestka, Jean-claude Latombe, Mark Overmars - IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION , 1996
"... A new motion planning method for robots in static workspaces is presented. This method proceeds in two phases: a learning phase and a query phase. In the learning phase, a probabilistic roadmap is constructed and stored as a graph whose nodes correspond to collision-free configurations and whose edg ..."

nodes. The method is general and easy to implement. It can be applied to virtually any type of holonomic robot. It requires selecting certain parameters (e.g., the duration of the learning phase) whose values depend on the scene, that is the robot and its workspace. But these values turn out

Random Early Detection Gateways for Congestion Avoidance.

by Sally Floyd , Van Jacobson - IEEELACM Transactions on Networking, , 1993
"... Abstract-This paper presents Random Early Detection (RED) gateways for congestion avoidance in packet-switched networks. The gateway detects incipient congestion by computing the average queue size. The gateway could notify connections of congestion either by dropping packets arriving at the gatewa ..."

by many active connections with a wide range of round-trip times, tolerances of delay, throughput requirements, etc. Decisions about the duration and magnitude of transient congestion to be allowed at the gateway are best made by the gateway itself. The method of monitoring the average queue size

Developing a Context-aware Electronic Tourist Guide: Some Issues and Experiences

by Keith Cheverst, Nigel Davies, Keith Mitchell, Adrian Friday, Christos Efstratiou , 2000
"... In this paper, we describe our experiences of developing and evaluating GUIDE, an intelligent electronic tourist guide. The GUIDE system has been built to overcome many of the limitations of the traditional information and navigation tools available to city visitors. For example, group-based tours a ..."

are inherently inflexible with fixed starting times and fixed durations and (like most guidebooks) are constrained by the need to satisfy the interests of the majority rather than the specific interests of individuals. Following a period of requirements capture, involving experts in the field of tourism, we

Eddies: Continuously Adaptive Query Processing

by Ron Avnur, Joseph M. Hellerstein - In SIGMOD , 2000
"... In large federated and shared-nothing databases, resources can exhibit widely fluctuating characteristics. Assumptions made at the time a query is submitted will rarely hold throughout the duration of query processing. As a result, traditional static query optimization and execution techniques are i ..."

The duration required to identify the instrument, the octave, or the pitch chroma of a musical note

by Ken Robinson, Roy D. Patterson - Music Perception , 1995
"... This paper investigates the role of pitch in the extraction of timbre information by measuring listeners ’ ability to identify the timbre, the octave, and the pitch chroma of musical notes, as a function of the duration of the notes. The stimuli were produced by one of four instrument types (brass, ..."

Automatic Symbolic Verification of Embedded Systems

by Rajeev Alur , Thomas A. Henzinger , Pei-hsin Ho , 1996
"... We present a model-checking procedure and its implementation for the automatic verification of embedded systems. The system components are described as Hybrid Automata -- communicating machines with finite control and real-valued variables that represent continuous environment parameters such as tim ..."

New Directions in Traffic Measurement and Accounting

by Cristian Estan, George Varghese , 2001
"... Accurate network traffic measurement is required for accounting, bandwidth provisioning, and detecting DOS attacks. However, keeping a counter to measure the traffic sent by each of a million concurrent flows is too expensive (using SRAM) or slow (using DRAM). The current state-of-the-art (e.g., Cis ..."

Scheduling Policies for an On-Demand Video Server with Batching

by Asit Dan, Dinkar Sitaram, Perwez Shahabuddin - in Proc. of ACM Multimedia , 1994
"... In an on-demand video server environment, clients make requests for movies to a centralized video server. Due to the stringent response time requirements, continuous delivery of a video stream to the client has to be guaranteed by reserving sufficient resources required to deliver a stream. Hence th ..."

Sensing-throughput tradeoff for cognitive radio networks

by Ying-chang Liang, Senior Member, Yonghong Zeng, Senior Member, Edward C. Y. Peh, Anh Tuan Hoang - in Proc. IEEE Int. Conf. Commun.(ICC , 2006

To support this spectrum reuse functionality, the secondary users are required to sense the radio frequency environment, and once the ..."

Developments in the Measurement of Subjective Well-Being
