Online Pump EfficiencyKnowing the efficiency of a pumping unit has important operational and financial benefits to those who operate the unit. Historically efficiency is collected on a periodic basis through on-site collection of the necessary parameters. Unit efficiency can be calculated on a real time basis by combining telemetered data with fluid properties in a Real Time Transient Model (RTTM). This method however needs to be validated in order to ensure it is equivalent to field efficiency testing. The RTTM was expanded to be able to calculate unit efficiency utilizing telemetered data and modeled fluid properties. Three crude oil and two refined products units were configured in the model to perform the calculations. Data from each of the units was stored in a relational database for later analysis. Date and time, efficiency ratio (current efficiency/manufacturer’s efficiency), flow rate and viscosity were stored once every fifteen minute. Field efficiency test data was retrieved and then compared to the telemetered data. A deviation of one percent or less was considered acceptable. Where the two methods did not correlate within the required one percent, the data was analyzed to determine the root cause. Errors in the model’s algorithms and potential errors in field data collection account for all departures. This research supports the use of the RTTM to calculate unit efficiency.
Reported condom use in students enrolled in a personal health and wellness course.When used consistently and correctly, condoms can prevent against the spread of sexually transmitted diseases (STD’s) and unplanned pregnancies. Condoms are a significant prevention method viable for all populations. This study was conducted using students at a Midwestern University who were enrolled in a personal health and wellness course and examined their reported use of condoms. This study involved voluntary participation of 275 personal health and wellness students. Results indicated that approximately 40% of the participants who reported being sexually active stated they did not use a condom during their last act of sex. The most common response for lack of condom use was “Trust in partners’ monogamy.” Females reported experiencing STD’s and unplanned pregnancies at a higher rate than the male population.
Thermal Protection of an Inductive Proximity Sensor Utilizing Low-Density Ceramic Composition TileThis thesis presents the results of a unique method for protecting inductive proximity (IP) sensors from extreme thermal exposure. The method presented in this study employs a barrier of ceramic tile material developed for the space shuttle program. While it may be intuitive that the ceramic tile material will provide adequate protection for extreme temperatures, what is not clear is the adaptability of this material to commercial use in a steel mill environment.One of the potential problems associated with using any thermal barrier is a partial or complete attenuation of the magnetic field generated by the sensor. To effectively utilize the shielding material in an application such as this it is necessary to understand the effect of the ceramic material on the magnetic field generated by the proximity sensor.In order to test the effectiveness of the ceramic tile to provide the level of thermal protection required and to discover if the tile will allow adequate magnetic field penetration for sensor detection, a series of two separate tests will be run. The first test will verify that the thermal shielding properties maintain the cool side temperature within the operational threshold of the sensor; the second test will establish the maximum sensing distance with the ceramic tile interposed between the sensor and the detectable object. This study determines if it is possible to consistently detect piping of 4” nominal diameter carbon steel pipe at a minimum specified distance from the shielding assembly.
Using Fuzzy Logic With Radio Frequency Identification To develop A Theoretical Model For Model For Monitoring Package PlacementEurope, the Middle East, Africa and the United States face problems of supply chain management and inventory control. Warehouse management is one of the biggest problems faced by pharmaceutical companies. Pharmaceutical companies maintain warehouses based on customer demands. Using several warehouse management systems in order to satisfy customized requirements of customers is an expensive process. Pharmaceutical companies seek for warehouse management solutions that support dynamic user defined configurations with variations in warehouse procedures including label printing, picking and sending the materials for processing and several others. Dealing with inventory control problems accounts for the largest cost component for the pharmaceutical industry. The challenge is to cut down these costs and simultaneously provide better management solutions. This thesis deals with the theoretical design of a fuzzy logic model interfaced with a radio frequency identification system that monitors drug placements in a pharmaceutical company’s warehouse. Fuzzy logic is the key interface that deals with the waste of pharmaceutical products while supplying to the customers.
