Abstract: Provided is a method including obtaining a corpus and an associated set of domain indicators. The method includes learning a set of vectors in an embedding space based on n-grams of the corpus. The method includes updating ontology graphs comprising a set of vertices and edges associating the set of vertices with each other. The method also includes determining a vector cluster using hierarchical clustering based on distances of the set of vectors with respect to each other in the embedding space and determining a hierarchy of the ontology graphs based on a set of domain indicators of a respective set of vertices corresponding to vectors of the vector cluster. The method also includes updating an index based on the ontology graphs.

Abstract: A waste water treatment system utilizing a series of individual modules which, when assembled, form a beginning contaminate collection chamber attached at the starting end of a main fluid treatment tank, in which is housed an array of anodes and cathodes. A center contaminate collection chamber can be attached at the oppose end of the main treatment tank which provides an internal fluid pathway to allow fluid transfer from the first treatment tank into a second treatment tank. Alternatively, the center contaminate collection chamber can be used when multiples of treatment tanks are assembled to work in tandem, or an ending contaminate collection chamber can be attached to an ending treatment module to complete the expandable waste water treatment system. Expandability of the system can therefore accommodate various waste water treatment mechanisms, residence time and manner of treatment.

Abstract: A process for removing oil and other organics, especially naphthalenic acid, is disclosed. The process involves use of electrical fields using electrodes in the device, inducing gas bubbles which force contaminants to the surface of the solutions to be skimmed off and recovered.

Abstract: A pet door is provided herein. The pet door includes a pivotal flap and a frame that defines a through-way. A rotatable knob is mounted to the frame and has a handle portion and a stop wall. The handle portion and stop wall include various profiles and configurations that work in concert to control the flap's direction of pivotal movement. In a first configuration, the flap may swing outwardly or inwardly. A second configuration prevents the flap from swinging inwardly. A third configuration prevents the flap from swinging outwardly. A fourth configuration places the flap is in a locked position to prevent swinging in either direction. The electronic door also includes an electronic latch mechanism which selectively latches and unlatches the flap. The latch mechanism unlatches the flap in response to a wireless signal from an electronic transmitter that may be affixed to a pet.

Abstract: A method of preparing micro-capsules. The active ingredient, preferably provided in the form of an acid salt dissolved in a basic aqueous solution, is emulsified into a polymer solution, preferably PLGA in a relatively volatile solvent such as dichloromethane, to create a water in oil emulsion. This emulsion is further emulsified into an aqueous solution having a pH of a between about 7.4 and 8.0 and most preferably between about 7.8 and 8.0 to create a water in oil in water solution. The polymer solvent is allowed to evaporate, causing the emulsified active ingredient and surrounding polymer matrix to precipitate, thereby forming the micro-capsules. The micro-capsules are separated from the suspension, washed and freeze dried. The method has a very high encapsulation efficiency, even at high loading rates. Additionally, the dissolution rate of the micro-particles produced by the method is very steady over a long period of time.
