• Thermal Protection of an Inductive Proximity Sensor Utilizing Low-Density Ceramic Composition Tile

      Anger, Kim
      This 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 Placement

      Sarikonda, Shruthi Reddy
      Europe, 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.
