LOF: Identifying density-based local outliers
- MOD
, 2000
"... For many KDD applications, such as detecting criminal activities in E-commerce, finding the rare instances or the outliers, can be more interesting than finding the common patterns. Existing work in outlier detection regards being an outlier as a binary property. In this paper, we contend that for ..."

Network Coding for Large Scale Content Distribution
"... We propose a new scheme for content distribution of large files that is based on network coding. With network coding, each node of the distribution network is able to generate and transmit encoded blocks of information. The randomization introduced by the coding process eases the scheduling of bloc ..."

-riding are in place. We demonstrate through simulations of scenarios of practical interest that the expected file download time improves by more than 20-30 % with network coding compared to coding at the server only and, by more than 2-3 times compared to sending unencoded information. Moreover, we show that network
Epidemic routing for partially-connected ad hoc networks
, 2000
"... Mobile ad hoc routing protocols allow nodes with wireless adaptors to communicate with one another without any pre-existing network infrastructure. Existing ad hoc routing protocols, while robust to rapidly changing network topology, assume the presence of a connected path from source to destination ..."
Zero-forcing methods for downlink spatial multiplexing in multiuser MIMO channels
- IEEE TRANS. SIGNAL PROCESSING
, 2004
"... The use of space-division multiple access (SDMA) in the downlink of a multiuser multiple-input, multiple-output (MIMO) wireless communications network can provide a substantial gain in system throughput. The challenge in such multiuser systems is designing transmit vectors while considering the co-c ..."

Typical optimization problems of interest include the capacity problem—maximizing the sum information rate subject to a power constraint—or the power control problem—minimizing transmitted power such that a certain quality-of-service metric for each user is met.

Efficient Capital Market: II” ,
- Journal of Finance, No
, 1991
"... SEQUELS ARE RARELY AS good as the originals, so I approach this review of the market efflciency literature with trepidation. The task is thornier than it was 20 years ago, when work on efficiency was rather new. The literature is now so large that a full review is impossible, and is not attempted h ..."

Comparison of routing metrics for static multi-hop wireless networks
- In ACM SIGCOMM
, 2004
"... Routing protocols for wireless ad hoc networks have traditionally focused on finding paths with minimum hop count. However, such paths can include slow or lossy links, leading to poor throughput. A routing algorithm can select better paths by explicitly taking the quality of the wireless links into ..."

that the ETX metric has the best performance when all nodes are stationary. We also find that the per-hop RTT and per-hop packet-pair metrics perform poorly due to self-interference. Interestingly, the hop-count metric outperforms all of the link-quality metrics in a scenario where the sender is mobile.
IMPORTANT: A framework to systematically analyze the Impact of Mobility on Performance of RouTing protocols for Adhoc NeTworks
- IEEE INFOCOM
, 2003
"... Abstract — A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Since not many MANETs are currently deployed, research in this area is mostly simulation based. Random Waypoint is the commonly used mobility mod ..."

However, we believe that it is not sufficient to capture some important mobility characteristics of scenarios in which MANETs may be deployed. Our framework aims to evaluate the impact of different

Significant work on the modeling of asset returns and other economic and financial processes is occurring within the actuarial profession, in support of risk-based capital analy-sis, dynamic financial analysis, pricing embedded options, solvency testing, and other financial applications. Although the results of most modeling efforts remain proprietary, two models are in the public domain. One is the CAS-SOA re-
Extracting Factors for Interest Rate Scenarios

The movements of a term structure of interest rates are commonly assumed to be driven by a small number of orthogonal factors such as SHIFT, T ..."

An Equilibrium Model of "Global Imbalances" and Low Interest Rates
- AMERICAN ECONOMIC REVIEW
, 2009

Three of the most important recent facts in global macroeconomics — the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio — appear as anomalies from the perspective of conventional wisdom and mode ..."
