Generating Log File Analyzers
… is to design an approach to generate log file analyzers based on a set of state machine specifications. Our analyzers are generated in C++ and are capable of reading log files from disk or shared memory areas. Regular expressions have been incorporated, so that analyzers can be adapted to …

Calibration of time domain network analyzers
A calibration technique for time domain reflectometry and transmission (TDR and TDT) measurement system as applied to network analysis is presented. The calibration corrects for the errors caused by the response of the measurement system. A complete physically-based model has been established for …

Securing software : an evaluation of static source code analyzers
This thesis evaluated five static analysis tools--Polyspace C Verifier, ARCHER, BOON, Splint, and UNO--using 14 code examples that illustrated actual buffer overflow vulnerabilities found in various versions of Sendmail, BIND, and WU-FTPD. Each code example included a "BAD" case with one or more …

Parameter Estimation from Retarding Potential Analyzers in the Presence of Realistic Noise
Retarding Potential Analyzers (RPA) have a rich flight heritage. These instruments are largely popular since a single current-voltage (I-V) profile can provide in-situ measurements of ion temperature, velocity and composition. The estimation of parameters from an RPA I-V curve is affected by grid …

Microblood Analyzers for the Sensitive and Portable Detection of Clinically Relevant Cardiac Markers
A laminar tube flow with 1st order wall reaction model was used for the cFABP microdevice assay, which could predict assay behavior for a range of conditions. The pseudo-first order reaction rate was estimated at ∼1.5x10-6 m/s, and it was determined that a 40 mum wide channel operated in the …

A critical study of various types of exhaust gas analyzers for gasoline engines
… tests consisted essentially of connecting the analyzers to the exhaust pipe of a single-cylinder engine and comparing the analyazer readings with the true air-fuel ratio determined by accurately measuring the air and fuel supplied to the engine while the instruments were being observed. This …

Real-time measurement of oxides of nitrogen from heavy-duty diesel engines
… diesel engines using two different NOx analyzers. Steady state and transient tests were conducted on six heavy-duty diesel engines in the WVU Engine and Emissions Research Center (EERC). NOx emissions were measured using a conventional Rosemount NOx analyzer and a Cambustion fast …
