Oceanstore: An architecture for global-scale persistent storage

by John Kubiatowicz, David Bindel, Yan Chen, Steven Czerwinski, Patrick Eaton, Dennis Geels, Ramakrishna Gummadi, Sean Rhea, Hakim Weatherspoon, Westley Weimer, Chris Wells, Ben Zhao , 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

Inferring Internet Denial-of-Service Activity

by David Moore, Geoffrey Voelker, Stefan Savage - In Proceedings of the 10th Usenix Security Symposium , 2001
"... In this paper, we seek to answer a simple question: "How prevalent are denial-of-service attacks in the Internet today?". Our motivation is to understand quantitatively the nature of the current threat as well as to enable longerterm analyses of trends and recurring patterns of attacks. We ..."

MATRIX FACTORIZATION TECHNIQUES FOR RECOMMENDER SYSTEMS

by Yehuda Koren, Robert Bell, Chris Volinsky - IEEE COMPUTER , 2009
"... As the Netflix Prize competition has demonstrated, matrix factorization models are superior to classic nearest-neighbor techniques for producing product recommendations, allowing the incorporation of additional information such as implicit feedback, temporal effects, and confidence levels. Modern co ..."

. Therefore, more retailers have become interested in recommender systems, which analyze patterns of user interest in products to provide personalized recommendations that suit a user’s taste. Because good personalized recommendations can add another dimension to the user experience, e-commerce leaders like

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 ..."

are designed to work with current gateways [15] could infer congestion from the estimated bottleneck service time or from changes in throughput or end-to-end delay, as well as from packet drops or other methods. Nevertheless, the view of an individual connection is limited by the time scales of the connection

Reexamining the Cluster Hypothesis: Scatter/Gather on Retrieval Results

by Marti A. Hearst, Jan O. Pedersen , 1996
"... We present Scatter/Gather, a cluster-based document browsing method, as an alternative to ranked titles for the organization and viewing of retrieval results. We systematically evaluate Scatter/Gather in this context and find significant improvements over similarity search ranking alone. This resul ..."
Abstract - Cited by 480 (5 self) - Add to MetaCart
Introduction An important service offered by an information access system is the organization of retrieval results. Conventional systems rank results based on an automatic assessment of relevance to the query [20]. Alternatives include graphical displays of interdocument similarity (e.g., [1, 22, 7

ATOMIC NEW SERVICE PATTERN

by Tchuta Leonard, Chunhua Gu
"... With emergence of Service Oriented Architecture (SOA) as the main technology for enterprise application development and integration, there is a need of service development patterns that fit into the context of SOA solutions development. This paper presents a pattern known as the atomic new service ( ..."

What memory is for

by Arthur M. Glenberg , 1997
"... Let’s start from scratch in thinking about what memory is for, and consequently, how it works. Suppose that memory and conceptualization work in the service of perception and action. In this case, conceptualization is the encoding of patterns of possible physical interaction with a three-dimensiona ..."

CONSTRUCTING BUSINESS SIMULATIONS WITH SERVICE PATTERNS

by Richard B. Lam
"... Typically, system dynamics-based simulations of business processes are constructed in an ad hoc manner, with a modeler creating low-level components and defining inter-relationships one-by-one. As the numbers of process com-ponents or variables grow, the resulting model becomes ever more difficult t ..."

to manage and extend. This paper dis-cusses the definition and use of high-level business pat-terns that have predefined system dynamics sub-models. These patterns enable rapid construction of arbitrarily complex system dynamics models of business processes through abstraction, reuse, and unification of sub

Autograph: Toward automated, distributed worm signature detection

by Hyang-ah Kim - In Proceedings of the 13th Usenix Security Symposium , 2004
"... Today’s Internet intrusion detection systems (IDSes) monitor edge networks ’ DMZs to identify and/or filter malicious flows. While an IDS helps protect the hosts on its local edge network from compromise and denial of service, it cannot alone effectively intervene to halt and reverse the spreading o ..."

UNIX Disk Access Patterns

by Chris Ruemmler, John Wilkes , 1993
"... Disk access patterns are becoming ever more important to understand as the gap between processor and disk performance increases. The study presented here is a detailed characterization of every lowlevel disk access generated by three quite different systems over a two month period. The contributions ..."
