Abstract: A heating apparatus for heating an object having a cylindrical outer peripheral surface includes: a support member for supporting the object to be heated; a covering member movable in the vertical directions relative to the support member and having inner wall surfaces with an open lower end, the inner wall surfaces defining an accommodation space for accommodating the object to be heated; the covering member closing the accommodation space when the covering member is disposed on the support member; the covering member allowing loading or unloading of the object to be heated when the covering member is separated from the support member; and a plurality of ring-shaped light sources each provided to surround the cylindrical outer peripheral surface of the object to be heated and arranged in the vertical direction in the accommodation space and radiating light for heating the object to be heated.

Abstract: Described herein are systems and methods of analyzing data acquired from a water plant, both historical and in real-time, making determinations about process and asset health diagnosis and anomaly detection using advanced techniques, and controlling the plant and/or providing alerts based on such determinations.

Abstract: An exemplary composite optical fiber transmission line and method are provided that result in significant advantages. The composite optical fiber transmission line includes a standard single-mode fiber, such as an SMF-28 fiber, a dispersion shifted fiber, such as an NZDSF fiber, and a dispersion compensating fiber. The single-mode fiber receives an input optical signal at a first end and generates a single-mode optical signal at a second end. The dispersion shifted fiber receives the single-mode optical signal at a first end and generates an output optical signal at a second end. The dispersion compensating fiber receives the output optical signal and generates a chromatic dispersion compensated optical signal that, preferably, is at some desired chromatic dispersion level. In one example, the residual chromatic dispersion of the composite optical fiber transmission line is zero or near zero, and the residual chromatic dispersion slope of the composite optical fiber transmission line is zero or near zero.
