RSS samplingAn Iterative Approach to Optimal Non-Uniform Sampling and Instantaneous Bandwidth Estimation
White Paper A new approach to the representation and reconstruction of non-bandlimited signals using non-uniform sampling schemes is introduced. This method is optimal in the sense that it requires the minimal sampling rate for exact reconstruction of the signal. [11 Jul 2008]
Distributed, Secure Load Balancing With Skew, Heterogeneity, and Churn
White Paper This algorithm, k-Choices, achieves load balance by greedily matching nodes' target workloads with actual applied workloads through limited sampling, and limits any fundamental decrease in security. Numerous proposals exist for load balancing in... [10 Jul 2008]
Enhancing Network Intrusion Detection With Integrated Sampling and Filtering
White Paper This "Secondary Path" supplements the "Main Path" by integrating sampling and richer forms of filtering into a NIDS's analysis. The structure of many standalone Network Intrusion Detection Systems (NIDSs) centers around a chain of analysis that... [08 Jul 2008]
Distributed Control of an XY Board Via Ethernet
White Paper The objective of this paper is to practically prove an adaptive sampling scheme to handle network delays and to highlight the potential of Switched Ethernet in implementing time critical real-time distributed control system applications. [08 Jul 2008]
Comparison of Two Sampling-Based Data Collection Mechanisms for Intrusion Detection System
White Paper Simple random sampling and Stratified random sampling techniques of statistics are introduced to the procedure of data collection for IDS, and formulas used to calculate the sample size of packets based on these sampling techniques are presented. [06 Jul 2008]
Capabilities and Employability of Unwed Mothers
White Paper This paper assesses the economic capabilities of a sample of unwed mothers who gave birth in the spring of 1998 in hospitals that serve low-income residents in seven cities that are part of a national sampling frame. [03 Jul 2008]
Java Performance Profiling Using the VTune Performance Analyzer
White Paper The two primary technologies used in the analysis are Call Graph and Time- and Event-Based Sampling. The Intel VTune Performance Analyzer has been used to tune C/C++ applications for years and the support the analyzer provides is fairly well known... [03 Jun 2008]
Geographic Surveillance and Hotspot Detection for Homeland Security: Drinking Water Quality and Water Utility Vulnerability
White Paper New York City has installed 892 drinking water sampling stations. An overall assessment of water quality at each sampling station taking all parameters into account is achieved by employing recent progress on multi-criterion ranking using poset... [10 Apr 2008]
