Abstract: The present technology is generally directed to integrated control of coke ovens in a coke plant in order to optimize coking rate, product recovery, byproducts and/or unit lime consumption. Optimization objectives are achieved through controlling certain variables (called control variables) by manipulating available handles (called manipulated variables) subject to constraints and system disturbances that affect the controlled variables.

Abstract: In one example, the present disclosure describes an antenna system with at least two linear antenna arrays, each having a plurality of antenna elements. Each array is designed to transmit and receive signals from different respective spectrum bands. The first antenna array and second antenna array are arranged to form one longer, combined linear array of antenna elements. In addition, at least one antenna element is shared between the first and second antenna arrays. In one example, the first antenna array is connected to a first RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the first antenna array and the second antenna array is connected to a second RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the second antenna array.

Abstract: In one example, an antenna system includes a radio base station for transmitting an RF signal via a transmission port, an RF splitting means for receiving the RF signal from the radio base station and for splitting the RF signal into two component signals, and at least two antennas separated by a distance greater than one wavelength and connected to the RF splitting means for transmitting the respective component signals such that an inferometric radiation gain pattern is created. The radio base station communicates with at least one mobile terminal via a dispersive multi-path radio channel where an angular spread of RF energy between the at least two antennas and the at least one mobile terminal causes nulls of the inferometric radiation pattern across a range of angles to be reduced.

Abstract: A sequential solid phase immunoassay and system is disclosed. The immunoassay utilizes the secondary antibody method for the detection of antibodies in a membrane-based test. The system comprises a test strip including a nitrocellulose membrane having an immobilized antigen in a capture zone on the membrane and a stabilized liquid secondary antibody conjugate. The sequential solid phase immunoassay is performed in a sequential manner with the addition of a fluid specimen being followed by the addition of the stabilized liquid secondary antibody conjugate. The sequential procedure using the system includes allowing the fluid specimen containing antibodies specific to the antigen to pass laterally from the test strip first end through the capture zone. The immobilized antigens in the capture zone capture antibodies specific to the antigen. The stabilized liquid secondary antibody conjugate then binds to the captured antibodies and can be detected visually or by a machine or reader.
