A Conceptual Framework and a Toolkit for Supporting the Rapid Prototyping of Context-Aware Applications

by Anind K. Dey, Gregory D. Abowd, Daniel Salber , 2001
"... Computing devices and applications are now used beyond the desktop, in diverse environments, and this trend toward ubiquitous computing is accelerating. One challenge that remains in this emerging research field is the ability to enhance the behavior of any application by informing it of the context ..."

-aware applications. In this paper, we address these three problems in turn. We first define context, identify categories of contextual information, and characterize context-aware application behavior. Though the full impact of context-aware computing requires understanding very subtle and high-level notions

Wide-area cooperative storage with CFS

by Frank Dabek, M. Frans Kaashoek, David Karger, Robert Morris, Ion Stoica , 2001
"... The Cooperative File System (CFS) is a new peer-to-peer readonly storage system that provides provable guarantees for the efficiency, robustness, and load-balance of file storage and retrieval. CFS does this with a completely decentralized architecture that can scale to large systems. CFS servers pr ..."

the Chord location protocol, which operates in time logarithmic in the number of servers. CFS is implemented using the SFS file system toolkit and runs on Linux, OpenBSD, and FreeBSD. Experience on a globally deployed prototype shows that CFS delivers data to clients as fast as FTP. Controlled tests show

DiamondTouch: a multi-user touch technology

by Paul Dietz, Darren Leigh , 2003
"... A technique for creating touch sensitive surfaces is proposed which allows multiple, simultaneous users to interact in an intuitive fashion. Touch location information is determined independently for each user, allowing each touch on the common surface to be associated with a particular user. The su ..."
Abstract - Cited by 591 (8 self) - Add to MetaCart
. The surface gnerates location dependent electric fields, which are capacitively coupled through the users to receivers installed in the work environment. We describe the design of these sytems and their applications. Finally, we conclude with a description of the results we have obtained with a first

FAST TCP: Motivation, Architecture, Algorithms, Performance

by C. Jin, D. X. Wei, S. H. Low , 2004
"... We describe FAST TCP, a new TCP congestion control algorithm for high-speed long-latency networks, from design to implementation. We highlight the approach taken by FAST TCP to address the four difficulties, at both packet and flow levels, which the current TCP implementation has at large windows. W ..."
Abstract - Cited by 369 (18 self) - Add to MetaCart
. We describe the architecture and characterize the equilibrium and stability properties of FAST TCP. We present experimental results comparing our first Linux prototype with TCP Reno, HSTCP, and STCP in terms of throughput, fairness, stability, and responsiveness. FAST TCP aims to rapidly stabilize

The anatomy of a large-scale hypertextual web search engine.

by Sergey Brin , Lawrence Page - Comput. Netw. ISDN Syst., , 1998
"... Abstract In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. The prototype with a fu ..."

TaintDroid: An Information-Flow Tracking System for Realtime Privacy Monitoring on Smartphones

by William Enck, Landon P. Cox, Jaeyeon Jung, et al. , 2010
"... Today’s smartphone operating systems fail to provide users with adequate control and visibility into how third-party applications use their private data. We present TaintDroid, an efficient, system-wide dynamic taint tracking and analysis system for the popular Android platform that can simultaneous ..."

, if any, perceivable overhead when running thirdparty applications. We use TaintDroid to study the behavior of 30 popular third-party Android applications and find several instances of misuse of users ’ private information. We believe that TaintDroid is the first working prototype demonstrating

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 ..."

or for expressing action (e.g., to set parameters or for initiating processes). We present three steps in the development of these ideas. First, as a note on research methodology, we outline a series of exploratory studies that were conducted. Secondly, we describe a prototype system called "Bricks &

Teddy: A sketching interface for 3d freeform design

by Takeo Igarashi, Satoshi Matsuoka, Hidehiko Tanaka , 1999
"... We present a sketching interface for quickly and easily designing freeform models such as stuffed animals and other rotund objects. The user draws several 2D freeform strokes interactively on the screen and the system automatically constructs plausible 3D polygonal surfaces. Our system supports seve ..."

several modeling operations, including the operation to construct a 3D polygonal surface from a 2D silhouette drawn by the user: it inflates the region surrounded by the silhouette making wide areas fat, and narrow areas thin. Teddy, our prototype system, is implemented as a Java ™ program, and the mesh

Safe Kernel Extensions Without Run-Time Checking

by George C. Necula, Peter Lee - Proc. of OSDI'96
"... Abstract This paper describes a mechanism by which an operating system kernel can determine with certainty that it is safe to execute a binary supplied by an untrusted source. The kernel first defines a safety policy and makes it public. Then, using this policy, an application can provide binaries i ..."

A First Step towards Automated Detection of Buffer Overrun Vulnerabilities

by David Wagner, Jeffrey S. Foster, Eric A. Brewer, Alexander Aiken - IN NETWORK AND DISTRIBUTED SYSTEM SECURITY SYMPOSIUM , 2000
"... We describe a new technique for finding potential buffer overrun vulnerabilities in security-critical C code. The key to success is to use static analysis: we formulate detection of buffer overruns as an integer range analysis problem. One major advantage of static analysis is that security bugs can ..."
