Abstract:
Systems and methods for accessing data stored in a data array, mapping the data using a bitmap index, and processing data queries by determining positions of query attributes in the bitmap index and locating values corresponding to the positions in the data array are described herein.
Abstract:
A method, system and program product for data evolution on column oriented databases is disclosed. For an input evolution operation, reusable and non-reusable attributes are identified. For attributes in a target schema that cannot be reused from the source schema, data and bitmap indexes of those attributes are generated from source data and bitmap indexes. A decompose operation is disclosed for decomposing a table into two tables. A merge operation is disclosed in which only one input table can be reused for mergence. A second merge operation is disclosed in which both input tables cannot be reused for mergence.
Abstract:
The invention discloses a dual frequency multiplexer by which a first and second coaxial harmonic oscillator type band pass filters are disposed in a box. The box includes a base body, a cover plate and a cover body. The two coaxial harmonic oscillator type hand pass filters are located on the base body and spaced each other by a metal plate; the multiplexer port, first and second ports are positioned on lateral side of the base body. The blocking capacitors are contained in the coaxial chamber of the two coaxial harmonic oscillator type band pass filters. The cover plate is secured on the base body; the first and second direct current circuits are placed on the cover plate; the low pass filters of the first and second direct current circuits are fixed on an edge of a top surface of the coaxial chamber by means of a support member; the cover body and the base body are fastened with each other. The blocking capacitors each are of distributed parameter capacitor. Utilization of distributed blocking capacitors makes the product of the invention small. Moreover, improvement of the structure of the invention brings effect such as less differential loss, large power capacity, as well as high isolation degree between circuits.
Abstract:
An apparatus includes a magnetic energy source to provide a magnetic signal and a detector to detect an acoustic energy signal from a sample stimulated by the magnetic energy signal. A method includes applying a magnetic signal to a biological sample, detecting an acoustic signal from the sample, and processing the acoustic signal to determine the electrical impedance distribution of the sample, and identify disease in the biological sample. A method includes applying a magnetic signal to a sample, detecting a magnetic or electrical signal within the sample, and processing the magnetic or electrical signal to reconstruct electrical impedance distribution of the sample.
Abstract:
A system and method for a vehicle is disclosed. Memory stores user profiles for a plurality of users. Each of the user profiles includes setting inputs for vehicle components and includes a wireless connection identifier for a wireless user device. The user selects his user profile in a user interface. A controller receives the selection from the user interface and obtains the setting inputs and the wireless connection identifier form the selected user profile in memory. The controller initiates one or more commands to the vehicle components having obtained setting inputs. In addition, the controller initiates a wireless connection between the wireless vehicle device and the wireless user device of the user using the wireless connection identifier.
Abstract:
Described herein is a non-invasive determination of locations of neural activity in a brain. In particular, methods and systems have been developed that utilize a FINES algorithm for use in three-dimensional (3-D) dipole source localization to locate neural activity in a brain.

The invention also discloses the preparation and uses of Bin1b protein and nucleic acid. Bin1b protein is useful to treat various diseases, e.g, urogenital infection. The invention also provides a pharmaceutical composition containing Bin1b protein.
Abstract:
Systems are disclosed of processing a set-level query across one or more attributes, the query being grouped by one or more attributes, whereby groups that satisfy the set-level query may be aggregated over one or more attributes. The systems use bitwise arithmetic to efficiently traverse bitmap and bit-slice vectors and indexes of a data relation to determine groups that solve the set-level query.
Abstract:
The present invention relates to a method and a positioning server in a radio access network for collecting radio fingerprint positioning data records from different nodes. The data records comprise geographical positions and radio network communication parameters and are stored and grouped in clusters in the positioning server. A geometrical shape representing a geographical area based on the network communication parameters in the collected positioning data records in the cluster is computed. When a notification about changed network configuration parameters for a radio cell is received, known positioning servers simply erase all positioning data records related to that radio cell. This results in the unavailability of still valid positioning data. The present invention overcomes this problem by selectively erase positioning data records in the positioning server only when the configuration parameters have changed beyond a predefined value range.
