An Efficient Method for Service Level Agreement Assessment
White Paper The paper observes, however, that the accurate estimation of network QoS parameters is not necessarily required for SLA assessment. On-line end-to-end Service Level Agreement (SLA) monitoring is of key importance nowadays. [12 Nov 2009]
Robust Control Tools for Traffic Monitoring in TCP/AQM Networks
White Paper Hence, appropriate robust control tools as quadratic separation are adopted to construct a delay dependent observer for TCP flows estimation. Several studies have considered control theory tools for traffic control in... [02 Oct 2009]
CFR and SNR Estimation Based on Complementary Golay Sequences for Single-Carrier Block Transmission in 60-GHz WPAN
White Paper However, MMSE-FDE needs the estimation of both the Channel Frequency Response (CFR) and the Signal-to-Noise Ratio (SNR). Through simulations, one proved that the proposed CFR and SNR estimation methods... [30 Aug 2009]
Data-Mining Discovery of Pattern and Process in Ecological Systems
White Paper Most ecologists use statistical methods as their main analytical tools when analyzing data to identify relationships between a response and a set of predictors; thus, they treat all analyses as hypothesis tests or exercises in parameter... [29 Aug 2009]
A Nonextensive Method for Spectroscopic Data Analysis With Artificial Neural Networks
White Paper The paper aims to assess the utility of the method based on statistical mechanics for the estimation of transparent coating material on security papers and cholesterol levels in blood samples. This paper applies an... [29 Aug 2009]
Research on Data Backup and Recovery Technology in SCADA System

RE-EM Trees: A New Data Mining Approach for Longitudinal Data
White Paper This paper presents a methodology that combines the flexibility of tree-based estimation methods with the structure of random effects models for longitudinal data. Longitudinal data refer to the situation where repeated... [29 Aug 2009]
H.264-Compatible Spatially Scalable Video Coding With In-band Prediction
White Paper In this paper, a H.264 compatible spatially scalable video coding method with in-band prediction is proposed which taking advantages from both the high coding efficiency of H.264 coding scheme and the attractive performance of in-band... [09 Jul 2009]
E-Mail Spam Filtering With Local SVM Classifiers
White Paper First, the selection of the right size of neighborhood is shown to be critical; their solution is based on the estimation of the a-posteriori probability of the correct decision, and the resulting algorithm is called... [01 Jul 2009]
Web Spam Challenge 2007 Track II Secure Computing Corporation Research
White Paper Stratified 3-fold cross validation for SVM and out-of-bag estimation for RF is used to tune the modeling parameters and estimate the generalization capability. To discriminate spam Web hosts/pages from normal ones,... [01 Jul 2009]
Hashed Samples: Selectivity Estimators for Set Similarity Selection Queries
White Paper This paper studies selectivity estimation techniques for set similarity queries. They show how to build robust samples a priori, based on existing synopses for distinct value estimation. A wide variety... [29 May 2009]
Getting the Most Out of the SAS Survey Procedures: Repeated Replication Methods, Subpopulation Analysis, and Missing Data Options in SAS V9.2
White Paper This paper presents practical guidance on three common survey data analysis techniques: repeated replication methods for variance estimation, subpopulation analyses, and techniques for handling missing data. [29 May 2009]
Using SAS Enterprise Guide 4.1 to Reduce the Cost of Diabetic Outpatients in Medicare
