  Citation × Citation Citation Abstract Copy Title: Real-time data quality assessment using linear prediction Author: Rentola, Christopher T. W. The U.S. Air Force models many naturally occurring phenomena. To validate such models, an automated data collection system is used. Since validation is dependent upon correct data, an inexpensive method to detect erroneous data was investigated. The method uses a Wiener filter to predict values one sample in advance. If the predicted value differs from the measured value by some constant, then erroneous data are detected. When applied to the meteorological parameter "temperature", a sixth-order filter was designed that would flag good data as correct 97.64% of the time with an error flag set at three standard deviations. This thesis outlines the software requirements, design, and testing necessary to use this method. Title: Real-time data quality assessment using linear prediction Author: Rentola, Christopher T. W.

  Citation × Citation Citation Abstract Copy Title: Modeling and characterization of hemt devices Author: Chang, Chujyh Different gate length (0.5 μm 16 μm) Al GaAs/GaAs and AIGaAs /InGaAs High Electron Mobility Transistors were electrically characterized in order to compare the room temperature DC device performance with one-dimensional device models. Model parameters such as the channel mobility and source/drain series resistances are extracted from independent measurement of the source-drain conductance characteristics. Using the saturated velocity as a fit parameter to the current voltage characteristics, good agreement with the expected value of this quantity is found in the two different systems.

  Citation × Citation Citation Abstract Copy Title: The electrical conductance of aqueous solutions in kaolin membranes Author: Sutton, Richard Frederich The relative conductance at room temperature of a solution in kaolin membranes was studied as a function of the volume fraction of the membrane. The resistances of the membrane and of the solution were measured for various volume fractions, and the conductance of the membrane relative to the solution was calculated. The relative conductance was linear with solid volume fraction over a range of volume fractions from 0.422 to 0.776. The equation was K[subscript m] = 1.337 - 1.673f where K[subscript m] is the ratio of the conductance of the membrane to the conductance of the solution, and f is the volume fraction of the membrane. At volume fractions less than 0.5, the relative conductance was definitely greater than would be expected from an inert membrane. The enhancernent of conductance was attributed to surface conduction along the pores of the membrane.

  Citation × Citation Citation Abstract Copy Title: An integrated analog multiplier circuit Author: Traa, Einar The exponential characteristic of the base-emitter Junction in bipolar transistors was used to make an accurate and fairly temperature independent multiplier. Using hybrid-pi transistor models and ECAP, a bandwidth of 350 MHz was predicted. Linearity is limited by emitter degeneration in the input differential stage rather than by the small errors in the actual multiplying stage. The multiplier was fabricated as a monolithic integrated circuit in the Tektronix integrated circuits laboratory. The prototype showed a bandwidth of 200 MHz, and a linearity of 2% over 50% of the dynamic range, when used as a variable gain amplifier.
