Projective Method for Generic Sensor Fusion Problem

Description: In a multiple sensor system, each sensor produces an output which is related to the desired feature according to a certain probability distribution. We propose a fuser that combines the sensor outputs to more accurately predict the desired feature. The fuser utilizes the lower envelope of regression curves of sensors to project the sensor with the least error at each point of the feature space. This fuser is optimal among all projective fusers and also satisfies the isolation property that ensu… more

Diesel Emission Control -- Sulfur Effects (DECSE) Program; Phase I Interim Data Report No. 1

Description: The Diesel Emission Control-Sulfur Effects (DECSE) is a joint government/industry program to determine the impact of diesel fuel sulfur levels on emission control systems whose use could lower emissions of nitrogen oxides (NO{sub x}) and particulate matter (PM) from on-highway trucks in the 2002--2004 model years. Phase 1 of the program was developed with the following objectives in mind: (1) evaluate the effects of varying the level of sulfur content in the fuel on the emission reduction perfo… more

Laser ultrasonic furnace tube coke monitor. Quarterly technical progress report. Report No. 5 for reporting period May 1, 1999 through August 1, 1999

Description: The overall aim of the project is to demonstrate the performance and practical use of a probe for measuring the thickness of coke deposits located within the high-temperature tubes of a thermal cracking furnace. The objective of work during this period was to enhance the sensitivity and signal-to-noise ratio of the probe measurement. Testing identified that the primary source of signal noise was traced to imperfections in the sacrificial stand-off, which was formed using a casting procedure. La… more

EVALUATION OF MODAL COMBINATION METHODS FOR SEISMIC RESPONSE SPECTRUM ANALYSIS.

Description: Regulatory Guide 1.92 ''Combining Modal Responses and Spatial Components in Seismic Response Analysis'' was last revised in 1976. The objective of this project was to re-evaluate the current regulatory guidance for combining modal responses in response spectrum analysis, evaluate recent technical developments, and recommend revisions to the regulatory guidance. This paper describes the qualitative evaluation of modal response combination methods.

Nrc-Bnl Benchmark Program on Evaluation of Methods for Seismic Analysis of Coupled Systems.

Description: A NRC-BNL benchmark program for evaluation of state-of-the-art analysis methods and computer programs for seismic analysis of coupled structures with non-classical damping is described. The program includes a series of benchmarking problems designed to investigate various aspects of complexities, applications and limitations associated with methods for analysis of non-classically damped structures. Discussions are provided on the benchmarking process, benchmark structural models, and the evalua… more
