Characterizing the fabric of the urban environment: A case study of Salt Lake City, Utah

Description: Urban fabric data are needed in order to estimate the impact of light-colored surfaces (roofs and pavements) and urban vegetation (trees, grass, shrubs) on the meteorology and air quality of a city, and to design effective implementation programs. In this report, we discuss the result of a semi-automatic Monte-Carlo statistical approach used to develop data on surface-type distribution and city-fabric makeup (percentage of various surface-types) using aerial color orthophotography. The digital … more

Dynamic Three-Dimensional Process Water Density Model for Ultrasim

Description: A temperature dependent D2O density model has been developed for the 3-D hydraulics module in the near real-time plant analysis code ULTRASIM. By replacing the constant density, ULTRASIM is improved in two ways. First, all 3-D hydraulic analyses performed are more physically realistic now that the temperature dependence of the D2O density is accounted for. Secondly, simple temperature driven process water transients can now be modeled and investigated, including natural circulation tests. This … more

Renewable Energy Power System Modular SIMulators: RPM-Sim User's Guide (Supersedes October 1999 edition)

Description: This version of the RPM-SIM User's Guide supersedes the October 1999 edition. Using the VisSimTM visual environment, researchers developed a modular simulation system to facilitate an application-specific, low-cost study of the system dynamics for wind-diesel hybrid power systems. This manual presents the principal modules of the simulator and, using case studies of a hybrid system, demonstrates some of the benefits that can be gained from understanding the effects of the designer's modificatio… more

Partitioning of Tank Waste Sludge in a 5-cm Centrifugal Contactor Under Caustic-Side Solvent Extraction Conditions

Description: A test program has been performed to evaluate the effect of solids on the hydraulic performance of a 5-cm centrifugal contactor under conditions present in the extraction section of the Caustic-Side Solvent Extraction (CSSX) process. In addition to determining if the ability to separate the aqueous and organic phases is affected by the presence of solids in a feed solution, the extent to which solids are accumulated in the contactor was also assessed. The reported task was motivated by the need… more

Steam Explosions in Slurry-fed Ceramic Melters

Description: This report assesses the potential and consequences of a steam explosion in Slurry Feed Ceramic Melters (SFCM). The principles that determine if an interaction is realistically probable within a SFCM are established. Also considered are the mitigating effects due to dissolved, non-condensable gas(es) and suspended solids within the slurry feed, radiation, high glass viscosity, and the existence of a cold cap. The report finds that, even if any explosion were to occur, however, it would not be l… more

Effect of Nitrite/Nitrate concentrations on Corrosivity of Washed Precipitate

Description: Cyclic polarization scans were performed using A-537 carbon steel in simulated washed precipitate solutions of various nitrite and nitrate concentrations. The results of this study indicate that nitrate is an aggressive anion in washed precipitate. Furthermore, a quantitative linear log-log relationship between the minimum effective nitrite concentration and the nitrate concentration was established for washed precipitate with other ions at their average compositions.

Flow Tones in a Pipeline-Cavity System: Effect of Pipe Asymmetry

Description: Flow tones in a pipeline-cavity system are characterized in terms of unsteady pressure within the cavity and along the pipe. The reference case corresponds to equal lengths of pipe connected to the inlet and outlet ends of the cavity. Varying degrees of asymmetry of this pipe arrangement are investigated. The asymmetry is achieved by an extension of variable length, which is added to the pipe at the cavity outlet. An extension length as small as a few percent of the acoustic wavelength of the r… more

Four-Dimensional Characterization of Paper Web at the Wet End

Description: This report presents a detailed description of a vision system whose purpose is to detect and to localize the nonuniformities that appear on the paper slurry (wood fiber and water mixture) at the wet end of a paper machine. Specifically, the system is capable of monitoring the paper slurry upon its exit from the headbox and alerting the operators of any event (e.g., streaks) that disrupts the otherwise homogeneous background. Such events are thought to affect crucial product properties such as … more

Kinetic and Thermodynamic Implications of some Commonly Used Rate Laws for Glass Dissolution

Description: This report discusses the results of the examination of three rate laws for glass dissolution. These three are: SLDF, LDF/LDF and ZO/LDF. All three models can fit the results of static powder leach tests reasonably well. The existence of a fundamental relationship between the thermodynamics and the kinetics of glass dissolution/leaching has been demonstrated for the three rate models.

Chemometric Classification of Unknown Vapors by Conversion of Sensor Array Pattern Vectors to Vapor Descriptors: Extension from Mass-Transducing Sensors To Volume-Transducing Sensors

Description: A new chemometric method was recently described for classifying unknowns by transforming the vector containing the responses from a multivariate detector to a vector containing descriptors of the detected analyte (Grate et al. 1999). This approach was derived for sensor arrays where each sensor's signal is proportional to the amount of vapor sorbed by a polymer on the sensor surface. In this case, the response is proportional to the partition coefficient, K, and the concentration of the vapor i… more

Polymers for Chemical Sensors Using Hydrosilylation Chemistry

Description: Sorbent and functionalized polymers play a key role in a diverse set of fields, including chemical sensors, separation membranes, solid phase extraction techniques, and chromatography. Sorbent polymers are critical to a number of sensor array or "electronic nose" systems. The responses of the sensors in the array give rise to patterns that can be used to distinguish one compound from another, provided that a sufficiently diverse set of sensing materials is present in the array.
