摘要： Techniques for EMD-based signal de-noising are disclosed that use statistical characteristics of IMFs to identify information-carrying IMFs for the purposes of partially reconstructing the identified relevant IMFs into a de-noised signal. The present disclosure has identified that the statistical characteristics of IMFs with noise tend to follow a generalized Gaussian distribution (GGD) versus only a Gaussian or Laplace distribution. Accordingly, a framework for relevant IMF selection is disclosed that includes, in part, performing a null hypothesis test against a distribution of each IMF derived from the use of a generalized probability density function (PDF). IMFs that contribute more noise than signal may thus be identified through the null hypothesis test. Conversely, the aspects and embodiments disclosed herein enable the determination of which IMFs have a contribution of more signal than noise. Thus, a signal may be partially reconstructed based on the predominately information-carrying IMFs to result in de-noised output signal.

摘要： The present disclosure is directed to filtering technologies that combine elements of continuous and batch NF/RO based on the constraints of the end-user facility to achieve a target balance between, for instance, recovery and power consumption, and to reduce long term operating cost of a plant. A method for extending batch operation into a second induction period with antiscalant injection is also disclosed herein, with the second induction period allowing for yet higher water recovery.

摘要： This present disclosure is generally directed to an optical isolator array with a magnetic base that allows for mounting and alignment of N number of optical isolators modules within an optical subassembly module. In an embodiment, the magnetic base provides at least one mounting surface for coupling to N number of optical isolators, with N being equal to an optical channel count for the optical subassembly (e.g., 4-channels, 8-channels, and so on). The magnetic base includes an overall width that allows for a desired number of optical isolators to get mounted thereon. Each optical isolator can be uniformly disposed along the same axis on the magnetic base and at a distance D from adjacent optical isolators. An adhesive such as ultraviolet-curing (UV-curing) optical adhesives may be used to secure each optical isolator at a predefined position and increase overall structural integrity.

摘要： One embodiment provides a method for resolving a forward error correction (FEC) protocol. The method includes requesting, by a network node element during an auto-negotiation period between the node element and a link partner, to resolve at least one FEC mode during a link training period; wherein the auto-negotiation period and the link training period are defined by an Ethernet communications protocol and the auto-negotiation period occurs before the link training period; determining, by the network node element, at least one channel quality parameter of at least one channel of a communication link between the network node element and the link partner; and determining, by the network node element during the link training period, whether to enable at least one FEC mode for use by the network node element based on, at least in part, the at least one channel quality parameter.
