The design of an acquisitional query processor for sensor networks

by Samuel Madden, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong - In SIGMOD , 2003
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."

Physical Design

by Jamie Bernard, Student Ms, Cpe George
"... Abstract—Very-Large-Scale-Integration (VLSI) of digital systems is the foundation of electronic applications that are used in everyday life. These applications vary from specialized parts to Application-Specific Integrated Circuits (ASIC), as well as Systems-On-Chips (SoCs). The designs of these sys ..."

of these systems are so complex that manual design would not be feasible. The only way to design and fabricate such complex designs is to use computers to automate portions of the design process. The focus of this paper are the numerous aspects of the physical design process and how those aspects are automated

Bricks: Laying the foundations for graspable user interfaces

by George W. Fitzmaurice , 1995
"... We introduce the concept of Graspable User Interfaces which allow direct control of electronic or virtual objects through physical handles for control. These physical artifacts are essentially new input devices which can be tightly coupled or “attached ” to virtual objects for manipulation or for ex ..."

;quot; and a sample application, GraspDraw, which was developed to investigate the Graspable UI concepts and to design new one- and twohanded interaction techniques. The physical artifacts, or bricks, operate on top of a large horizontal display surface known as the ActiveDesk. Finally, we conclude

Live Migration of Virtual Machines

by Christopher Clark, Keir Fraser, Steven H, Jakob Gorm Hansen, Eric Jul, Christian Limpach, Ian Pratt, Andrew Warfield - In Proceedings of the 2nd ACM/USENIX Symposium on Networked Systems Design and Implementation (NSDI , 2005
"... Migrating operating system instances across distinct physical hosts is a useful tool for administrators of data centers and clusters: It allows a clean separation between hardware and software, and facilitates fault management, load balancing, and low-level system maintenance. By carrying out the ma ..."

System architecture directions for networked sensors

by Jason Hill, Robert Szewczyk, Alec Woo, Seth Hollar, David Culler, Kristofer Pister - IN ARCHITECTURAL SUPPORT FOR PROGRAMMING LANGUAGES AND OPERATING SYSTEMS , 2000
"... Technological progress in integrated, low-power, CMOS communication devices and sensors makes a rich design space of networked sensors viable. They can be deeply embedded in the physical world or spread throughout our environment. The missing elements are an overall system architecture and a methodo ..."

The Cougar Approach to In-Network Query Processing in Sensor Networks

by Yong Yao, Johannes Gehrke - SIGMOD Record , 2002
"... The widespread distribution and availability of smallscale sensors, actuators, and embedded processors is transforming the physical world into a computing platform. One such example is a sensor network consisting of a large number of sensor nodes that combine physical sensing capabilities such as te ..."

The synchronous dataflow programming language LUSTRE

by N. Halbwachs, P. Caspi, P. Raymond, D. Pilaud - Proceedings of the IEEE , 1991
"... This paper describes the language Lustre, which is a dataflow synchronous language, designed for programming reactive systems --- such as automatic control and monitoring systems --- as well as for describing hardware. The dataflow aspect of Lustre makes it very close to usual description tools in t ..."

Randomized kinodynamic planning

by Steven M. Lavalle, James J. Kuffner, Jr. - THE INTERNATIONAL JOURNAL OF ROBOTICS RESEARCH 2001; 20; 378 , 2001
"... This paper presents the first randomized approach to kinodynamic planning (also known as trajectory planning or trajectory design). The task is to determine control inputs to drive a robot from an initial configuration and velocity to a goal configuration and velocity while obeying physically based ..."

DSR: The Dynamic Source Routing Protocol for Multi-Hop Wireless Ad Hoc Networks”, in Ad Hoc Networking, edited by Charles E.

by David B Johnson , David A Maltz , Josh Broch - 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 ..."

experimentation in a physical outdoor ad hoc networking testbed we have constructed in Pittsburgh, and have demonstrated the excellent performance of the protocol. In this chapter, we describe the design of DSR and provide a summary of some of our simulation and testbed implementation results for the protocol.
