Practical network support for IP traceback

by Stefan Savage, David Wetherall, Anna Karlin, Tom Anderson , 2000
"... This paper describes a technique for tracing anonymous packet flooding attacks in the Internet back towards their source. This work is motivated by the increased frequency and sophistication of denial-of-service attacks and by the difficulty in tracing packets with incorrect, or “spoofed”, source ad ..."

Imagenet: A large-scale hierarchical image database

by Jia Deng, Wei Dong, Richard Socher, Li-jia Li, Kai Li, Li Fei-fei - In CVPR , 2009
"... The explosion of image data on the Internet has the potential to foster more sophisticated and robust models and algorithms to index, retrieve, organize and interact with images and multimedia data. But exactly how such data can be harnessed and organized remains a critical problem. We introduce her ..."

The physiology of the grid: An open grid services architecture for distributed systems integration

by Ian Foster , 2002
"... In both e-business and e-science, we often need to integrate services across distributed, heterogeneous, dynamic “virtual organizations ” formed from the disparate resources within a single enterprise and/or from external resource sharing and service provider relationships. This integration can be t ..."

The process group approach to reliable distributed computing

by Kenneth P. Birman - Communications of the ACM , 1993
"... The difficulty of developing reliable distributed softwme is an impediment to applying distributed computing technology in many settings. Expeti _ with the Isis system suggests that a structured approach based on virtually synchronous _ groups yields systems that are substantially easier to develop, ..."

Real-Time Dynamic Voltage Scaling for Low-Power Embedded Operating Systems

by Padmanabhan Pillai, Kang G. Shin , 2001
"... In recent years, there has been a rapid and wide spread of nontraditional computing platforms, especially mobile and portable computing devices. As applications become increasingly sophisticated and processing power increases, the most serious limitation on these devices is the available battery lif ..."

The Simple Economics of Basic Scientific Research

by Richard R. Nelson - Journal of Political Economy , 1959
"... I begin this essay by reflecting on my early paper (Nelson, 1859), and Ken’s (Arrow, 1962), as period pieces. These papers certainly have been influential in shaping the discussion of science and technology policy over the last forty years, at least among economists, but at the time they were writte ..."

written, economists were just beginning to get into analysis of the key processes and institutions involved in technological advance. A lot has been learned since that time, and the discussion has become much more sophisticated. I will highlight two of those intellectual developments: the growing

Efficient Filtering of XML Documents for Selective Dissemination of Information

by Mehmet Altınel , 2000
"... Information Dissemination applications are gaining increasing popularity due to dramatic improvements in communications bandwidth and ubiquity. The sheer volume of data available necessitates the use of selective approaches to dissemination in order to avoid overwhelming users with unnecessaryi ..."

sophisticated filtering mechanisms that take structure information into account. We have developed several index organizations and search algorithms for performing efficient filtering of XML documents for large-scale information dissemination systems. In this paper we describe these techniques and examine

There is more to Context than Location

by Albrecht Schmidt, Michael Beigl, Hans-w. Gellersen - Computers and Graphics , 1998
"... Context is a key issue in interaction between human and computer, describing the surrounding facts that add meaning. In mobile computing research published the parameter location is most often used to approximate context and to implement context-aware applications. We propose that ultra-mobile compu ..."
Abstract - Cited by 300 (14 self) - Add to MetaCart
-mobile computing, characterized by devices that are operational and operated while on the move (e.g. PDAs, mobile phones, wearable computers), can significantly benefit from a wider notion of context. To structure the field we introduce a working model for context, discuss mechanisms to acquire context beyond

Sophisticated momenta mapping with DIANA

by M. Tentyukov Ab, J. Fleischer B , 2005
"... Details of recent developments of the Feynman diagram analyzer DIANA (DIagram ANAlyser) are presented. Apart from some discussion about QGRAF and new plotting features, we concentrate on a new sophisticated mechanism of momenta mapping. The C-program DIANA (DIagram ANAlyser) for the automatic Feynma ..."
