An intrusion-detection model

by Dorothy E. Denning - IEEE TRANSACTIONS ON SOFTWARE ENGINEERING , 1987
"... A model of a real-time intrusion-detection expert system capable of detecting break-ins, penetrations, and other forms of computer abuse is described. The model is based on the hypothesis that security violations can be detected by monitoring a system's audit records for abnormal patterns of sy ..."

of system usage. The model includes profiles for representing the behavior of subjects with respect to objects in terms of metrics and statistical models, and rules for acquiring knowledge about this behavior from audit records and for detecting anomalous behavior. The model is independent of any particular

Overview of the scalable video coding extension of the H.264/AVC standard

by Heiko Schwarz, Detlev Marpe, Thomas Wiegand - IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY IN CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY , 2007
"... With the introduction of the H.264/AVC video coding standard, significant improvements have recently been demonstrated in video compression capability. The Joint Video Team of the ITU-T VCEG and the ISO/IEC MPEG has now also standardized a Scalable Video Coding (SVC) extension of the H.264/AVC stand ..."

such as graceful degradation in lossy transmission environments as well as bit rate, format, and power adaptation. These functionalities provide enhancements to transmission and storage applications. SVC has achieved significant improvements in coding efficiency with an increased degree of supported scalability

ANALYSIS OF WIRELESS SENSOR NETWORKS FOR HABITAT MONITORING

by Joseph Polastre, Robert Szewczyk, Alan Mainwaring, David Culler, John Anderson , 2004
"... We provide an in-depth study of applying wireless sensor networks (WSNs) to real-world habitat monitoring. A set of system design requirements were developed that cover the hardware design of the nodes, the sensor network software, protective enclosures, and system architecture to meet the require ..."

present a set of experiences from a four month long deployment on a remote island. We analyze the environmental and node health data to evaluate system performance. The close integration of WSNs with their environment provides environmental data at densities previously impossible. We show that the sensor

gprof: a Call Graph Execution Profiler

by Susan L. Graham, Peter B. Kessler, Marshall K. McKusick , 1982
"... Large complex programs are composed of many small routines that implement abstractions for the routines that call them. To be useful, an execution profiler must attribute execution time in a way that is significant for the logical structure of a program as well as for its textual decomposition. This ..."

TAPE: A transactional application profiling environment

by Hassan Chafi, Chi Cao Minh, Austen Mcdonald, Brian D. Carlstrom, Jaewoong Chung, Lance Hammond, Christos Kozyrakis, Kunle Olukotun - In ICS ’05: Proceedings of the 19th Annual International Conference on Supercomputing , 2005
"... Transactional Coherence and Consistency (TCC) provides a new parallel programming model that uses transactions as the basic unit of parallel work and communication. TCC simplifies the development of correct parallel code because hardware provides transaction atomicity and ordering. Nevertheless, the ..."

, the programmer or a dynamic compiler must still optimize the parallel code for performance. This paper presents TAPE, a hardware and software infrastructure for profiling in TCC systems. TAPE extends the hardware for transactional execution to identify performance impediments such as dependence violations

Scalability and Accuracy in a Large-Scale Network Emulator

by Amin Vahdat, Ken Yocum, Kevin Walsh, Priya Mahadevan, Dejan Kostić, Jeff Chase, David Becker - IN PROCEEDINGS OF THE 5TH SYMPOSIUM ON OPERATING SYSTEMS DESIGN AND IMPLEMENTATION (OSDI , 2002
"... This paper presents ModelNet, a scalable Internet emulation environment that enables researchers to deploy unmodified software prototypes in a configurable Internet-like environment and subject them to faults and varying network conditions. Edge nodes running user-specified OS and application softwa ..."

Lessons From A Sensor Network Expedition

by Robert Szewczyk, Joseph Polastre, Alan Mainwaring, David Culler , 2004
"... Habitat monitoring is an important driving application for wireless sensor networks (WSNs). Although researchers anticipate some challenges arising in the real-world deployments of sensor networks, a number of problems can be discovered only through experience. This paper evaluates a sensor network ..."
