摘要:
The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of an additive aromatic compound tri-substituted with acidic functionalities selected from 5-hydroxyisophthalic acid and 1,3,5-benzenetricarboxylic acid, typically up to 1000 wppm, to the metal surface.

A rotordynamic machine for the forwarding of a fluid, such as a turbomachine (2) or a centrifugal pump, has at least one drive and bearing apparatus (1) which is designed as an electrical machine with a stator and with a magnetically journalled rotor (4a). Electrical windings (15, 16) produce the required torque and the magnetic bearing force and are arranged together in the stator. The rotor (4a) forms a section of the shaft (4) of the turbomachine (2) and a control apparatus (7) and excites the two windings (15, 16). A magnetic suspension force acting on the rotor (4a) is produced with the first winding (16) in order to hold the shaft (4) in the radial direction without contact. The torque acting on the rotor (4a) is produced with the second winding (15).

In an embodiment, a method of providing a personalized display of data is presented. In this method, an identity of each of multiple applications for displaying data is transmitted to a user device, such as, for example, a computer or mobile communication device. Selections of more than one of the multiple applications are received from the user device. Configuration data indicating the selected applications are generated and stored. A request for a presentation application is received from the user device. The presentation application is to display the data via execution of the selected applications. In response to the request, the presentation application is generated based on the configuration data, and includes the selected applications. The presentation application is then transmitted to the user device for execution.
摘要:
A benchmarking computing application is configured to create a benchmark run for a segment of customer profiles. Customer profiles from the segment include a parameter, termed an adjustment parameter, that may affect energy consumption by the associated customer. The results of the benchmark run include energy consumption values for individual customer profiles in the segment, an average energy consumption value for the entire segment of customer profiles, and also adjustment energy consumption value. The adjustment energy consumption value reflects the portion of energy consumption by a particular customer attributed to the difference between the average value of the adjustment parameter for the segment and the value of the adjustment parameter for the particular customer profile.

A method and a system for measuring market data in a mobile communications system. The method and system may be used to obtain data such as growth, churn rate, and other measurable metrics of mobile communications device subscribers. The method includes selecting a sample of contact numbers, using one or more contacting or querying methodologies to assess the state of the contact numbers, and analyzing the results to determine the market data.
摘要:
In an embodiment, a method of providing an arranged display of data associated with a set of time periods is presented. In this method, values of a first data type are accessed, the values being observed during each of multiple time periods. An order for the time periods is determined based on the values of the first data type. A selectable region for each of the time periods is displayed, the regions being arranged according to the order. In response to a user selection of one of the selectable regions, a value of a second data type is displayed, the value of the second data type being observed during the time period of the selected one of the selectable regions.
