    摘要： An optical theta-modulation based analog-to-digital converter having an acousto-optic deflector and an analog-to-digital conversion mask, for fast and flexible analog-to-digital conversion. The acousto-optic deflector deflects an optical beam at an angle corresponding to an input voltage signal having an analog value. The analog-to-digital conversion mask converts the deflected optical beam into N masked optical signals which each corresponds to a respective bit of a digital value representing the analog value of the input signal. Each optical signal is detected by a photodetector and converted into an output voltage signal by a comparator.

    摘要： Methods and systems are provided for intelligently detecting pipeline small leaks and thefts. In the Energy Flow Line Method, measured changes in flow data at both ends of the pipeline are monitored and analyzed to detect a leak or a theft. The energy wave front speed and the unsteady flow mathematical model of the subject pipeline is used to calculate leak details. In the Filtered Pressure Waves Method, the measured pressure data at both ends of the pipeline is monitored and analyzed. Pressure waves that do not originate at the ends of the pipeline are selected. Two travelling time windows are applied to those candidates, and the candidates are processed within each window. Leaks, thefts and their details are obtained if the detected leak locations meet the criteria. The Enhanced Filtered Pressure Waves Method, provides the leaked amount and verifies the leak and the leak location to avoid false alarms. An index formed with measured parameters is monitored and the unsteady flow model of the subject pipeline is utilized.

    摘要： A computerized system and method comprises a predictive model for estimating the probability of a patient hospital readmission. The computerized system and method is useful for identifying patients at risk of hospital readmission and further identifying an intervention to mitigate the risk and reduce the likelihood that the patient returns to the hospital. The computerized system method collects and analyzes historical health data from administrative claims data and current health data collected in real-time from medical records at the point of treatment. Signals indicating readmission are extracted from the health data that is collected. The signals are evaluated by the model software application to estimate a probability that a patient will be readmitted to the hospital. Patients with a high readmissions probability score are selected for clinical programs and interventions that help them manage their health conditions and problems and reduce the likelihood that they return to the hospital.

    摘要： The present invention provides a method for synthesizing cationic bleach activators via a single-bath reaction, comprising steps of: separately dissolving 4-chloromethylbenoyl chloride and lactam in its respective solvent, adding an acid-binding agent to the lactam solution, next adding dropwisely 4-chloromethylbenoyl chloride solution into the lactam/acid binding-agent solution, and finally adding tertiary amine to the solution above to make a reaction solution, which is further treated with mixing and refluxing. The washed and dried final product is TBLC cationic bleach activator. The method of the present invention greatly simplifies the synthesizing process and lowers the stringency of reaction conditions for preparing cationic bleach activators (TBLC). At the same time, the present method produces TBLC cationic bleach activators with high yields, making it a suitable option for industrial production of these bleach activators.
