Improving the Quality of Hotel Banquet Staff Performance: a Case Study in Organizational Behavior Management

Description: The banquet staff at a north Texas hotel were responsible for setting up 11 different functions (e.g., buffet dinners) for conferences and meetings. The functions were often set up late and items were often omitted. An analysis suggested that performance problems were the result of weak antecedents, inefficient work procedures, inadequate training and a lack of motivating consequences. An intervention consisting of task checklists, feedback, goal setting, monetary bonuses, training and job aids… more

SFE Fractionation and RP-HPLC Characterization of Aquatic Fulvic Acid

Description: The Supercritical Fluid Extraction (SFE) technique was used to fractionate Suwannee River reference fulvic acid (FA). The fractions were characterized by gas chromatography (GC) and reversed-phase high performance liquid chromatography (RP-HPLC). A SFE fractionation method was developed using stepwise gradient of supercritical CO₂ and methanol. Three FA fractions were separated. The average mass recovery was 102% with the coefficient of variation of 2.8%. The fractionation dynamics and the diff… more

Operation and tests of a DDC101 A/D

Description: For the KTeV PMT laser monitoring system, one needs a high resolution device with a large dynamic range to be used for digitizing PIN photodiodes. The dynamic range should be wider than or comparable to the KTeV digitizer (17-bits). The Burr-Brown DDC101 is a precision, wide dynamic range, charge digitizing A/D converter with 20-bit resolution, packaged in a 28-pin plastic, double-wide DP. Low level current output devices, such as photosensors can be directly connected to its input. The digital… more

Thermal modeling of the lithium/polymer battery

Description: Research in the area of advanced batteries for electric-vehicle applications has increased steadily since the 1990 zero-emission-vehicle mandate of the California Air Resources Board. Due to their design flexibility and potentially high energy and power densities, lithium/polymer batteries are an emerging technology for electric-vehicle applications. Thermal modeling of lithium/polymer batteries is particularly important because the transport properties of the system depend exponentially on tem… more

Adventures in the evolution of a high-bandwidth network for central servers

Description: In a small network, clients and servers may all be connected to a single Ethernet without significant performance concerns. As the number of clients on a network grows, the necessity of splitting the network into multiple sub-networks, each with a manageable number of clients, becomes clear. Less obvious is what to do with the servers. Group file servers on subnets and multihomed servers offer only partial solutions -- many other types of servers do not lend themselves to a decentralized model,… more

A comparison of NH{sub 3} point monitoring and diode laser based path integrated measurements

Description: Measurements made using two different types of ammonia monitors during a two-month field study in the summer of 1994 are discussed. The first was a diode-laser based open path monitor designed for automated operation in an industrial environment. The second is a monitoring analyzer based on thermal decomposition of ammonia to NO and subsequent analysis by O{sub 3}-NO chemiluminescence. The two monitors provided consistent measurements of ammonia concentration during weeks of continuous unattend… more

Unique passive diagnostic for slapper detonators

Description: The objective of this study was to find a material and configuration that could reliably detect the proper functioning of a current slapper detonator. Because of the small size of the slapper geometry (on the order of a 15 mils), most diagnostic techniques are not suitable. This program has the additional requirement that the device could not use any electrical power or output signals. This required that the diagnostic be completely passive. The paper describes the three facets of the developme… more

Transport simulation of negative magnetic shear discharges

Description: In the present work the authors present simulations which show that the hollow current profile can be maintained in quasi-steady state through a self-consistently determined combination of bootstrap current and neutral beam and rf current drive. Controllability of the q profile is demonstrated by eliminating low m/n mode number instabilities from these discharges by maintaining q > 1.5 at all times, starting from appropriate initial conditions. At moderately high {beta}{sub p}, the bootstrap cu… more

Removal of cesium from aluminum decladding wastes generated in irradiated target processing using a fixed-bed column of resorcinol-formaldehyde resin

Description: The removal of cesium (Cs) from a low-level liquid waste (LLLW) with a cation-exchange column was demonstrated using a resorcinol-formaldehyde (RF) resin. The RF resin was developed at the Westinghouse Savannah River Laboratory (SRL) and is highly specific for the removal of Cs from an alkaline waste of high sodium content. It was determined that the RF resin would be suitable for removing Cs, the largest gamma radiation contributor, from the LLLW generated at the Radiochemical Engineering Deve… more

Green River Formation water flood demonstration project. Report for the period October 1992--March 1994

Description: The current project targeted three fluvial deltaic reservoirs in the Uinta Basin, Utah. In primary recovery, the performance of the Monument Butte unit was typical of an undersaturated reservoir whose initial pressure was close to the bubble point pressure. The unit was producing at a rate of 40 stb/day when the water flood was initiated. The unit has been producing at more than 300 stb/day for the past four years. The reservoir characteristics of Monument Butte were established in the geologic… more
