Abstract: An ambient pressure compensation structure for an ultraviolet difference spectrum gas sensor includes a closed box, an ultraviolet difference spectrum gas sensor, a digital pressure sensor, a thermostatic controller, an industrial control computer, a pressure regulating assembly and a limiting partition; the pressure regulating assembly and the limiting partition are arranged inside the closed box, the pressure regulating assembly comprises a piston, a regulating rod and a driving motor, the left side of the piston is connected with the regulating rod, the front end of the regulating rod penetrates out of the closed box and is connected with the driving motor, and the piston divides the interior of the closed box into a pressure regulating air chamber and a working air chamber. Also disclosed is an ambient pressure compensation method for an ultraviolet difference spectrum gas sensor.

Abstract: A system may include a server and a data store system. The server may include at least one storage device and at least one processor. The server may execute an application and may store an encrypted password. The data store system may include at least one persistent storage device configured to store a data store. The data store system may further include a plurality of processing nodes configured to operate on the data store. The data store system may receive the encrypted password from the application with one of the plurality of processing nodes and may decrypt the encrypted password with the one of the plurality of processing nodes. The data store system may authenticate the decrypted password with the one of the processing nodes and provide the decrypted password to other processing nodes. Each processing node that has the decrypted password may be accessible to the application to operate on the data store. A method and computer-readable medium may also be implemented.

Abstract: Techniques for processing relational data with a user-defined function (UDF) are provided. Relational input data being requested by the UDF, from within a relational database system, is intercepted and normalized. The UDF is called with the normalized input data and as the UDF produces output data in response to the normalized input data that output data is captured and normalized. In an embodiment, the normalized output data is used to dynamically update a data model within the relational database for the input data.

Abstract: Demand Chain Management (DCM) refers to a suite of analytical applications for retail business, that provides retailers with the tools they need for product demand forecasting, planning and replenishment. The reliable development and user-friendly interface of DCM applications ensures improved customer satisfaction, increased sales, improved inventory turns and significant return on investment. The present subject matter provides a self-contained reusable smart cache component for DCM development and interface. The smart cache component gives a DCM developer the ability to automatically have a configurable amount of information temporarily stored in readily available memory on an application server. The information can be retrieved in a high speed fashion without the need for additional calls to the original location of the information.

Abstract: Apparatus, systems, and methods may operate to receive a designation of multiple rows to supply data to a single user defined function, which is made available in a structured query language SELECT statement. Further activities may include retrieving the data from at least one storage medium, packing each of the multiple rows having a common key into a single row, and transforming the data from a first state into a second state by applying the single function to the data using a single access module processor. Other apparatus, systems, and methods are disclosed.
