Abstract: A bendable core insert configured for manufacturing a golf-club shaft. The bendable core includes a bendable relief tube having a first end attached to a top coupling tube and a second end attached to a bottom coupling tube. The bendable relief tube, the top coupling tube, and the bottom coupling tube have respective channels that are aligned to form a continuous channel through opposing ends of the bendable core insert. The length of the bendable core insert corresponds to a length of a corresponding segment of the golf-club shaft. The bendable relief tube is configured to be bent in one or more directions to define a bend profile of the corresponding segment of the golf-club shaft.

Abstract: This disclosure relates to a device for changing a gear of a bicycle. The device can include a casing, a lever moveable relative to the casing for actuating a gear change of a bicycle, and a rail arranged on the casing, wherein the rail extends between a first end and a second end. The lever can be configured to move along a length direction of the rail, which extends between the first end and the second end of the rail, for actuating the gear change of the bicycle. The rail can extend about a width direction and project from the casing about a height direction. The casing can include a flange located at the second end of the rail, and the flange can be configured for inhibiting the lever to continue moving beyond the second end of the rail in a direction which extends away from both the first end and the second end of the rail. The flange can at least partially span a width of the rail.

Abstract: A method of accessing objects with fine-grained access control (FGAC) in a relational database management system (RDBMS) storing a segmented column-major database. For each object with access restrictions, an artificial neural network (ANN), is trained by generating an equally distributed segment map of segmented data entries, so that the map reproduces the row disposition in the unsegmented object. When a user access request is received, these ANNs are referred to determine if any of the objects to be accessed are subject to access restrictions. If that is the case, then the ANN creates a pseudo-view construct of its associated object which is limited to data entries that the user has permission to access. The pseudo-views are then injected into the user access request to embed the fine-grained access controls for subsequent processing of the request, which can then proceed without further regard to user-specific access restrictions.

Abstract: A method of forming an LMNO cathode with electrolytic manganese dioxide includes dissolving metallic manganese in acid to create a dissolved manganese solution, disposing the solution within an electrolytic cell including an electrolytic cell anode and an electrolytic cell cathode, and applying a current between the cell anode and the cell cathode to the solution. Applying the current forms an MnO2 deposit upon the cell anode. The method further includes harvesting the deposit, creating a manganese precursor by neutralizing the deposit and grinding the deposit to form an MnO2 powder, and mixing the manganese precursor with a nickel precursor and a lithium precursor to create a mixture. The method further includes calcining the mixture to create an LMNO powder and coating a current collector with the LMNO powder to thereby form the LMNO cathode. The method may include testing the cathode electrode in an electrochemical pouch format cell.

The electromagnetic valve actuator is for at least one valve of an internal combustion engine, the electromagnetic valve actuator comprising: a rotor; a stator for rotating the rotor; output means for actuating the valve in dependence on rotation of the rotor; mechanical energy storage means arranged to store energy in dependence on rotation of the rotor and release the energy to assist rotation of the rotor and phase varying means for varying a phase between the mechanical energy storage means and the output means.

Abstract: Concepts for processing a SQL statement comprising a ROLAP sort operation are presented. One such concept comprises: determining whether a ROLAP partitioning column of the SQL statement does not refer to database columns from a sort operation of the SQL statement; and determining whether the ROLAP partitioning columns of the SQL statement are all referenced in the output of the SQL statement. Responsive to determining a ROLAP partitioning column of the SQL statement does not refer to database columns from a sort operation of the SQL statement, and to determining all of the ROLAP partitioning columns of the SQL statement are referenced in the output of the SQL statement, the SQL statement is modified by removing the ROLAP sort operation from the SQL statement.

Abstract: Embodiments of the present invention provide systems and methods for associating rule mining in data comprising first and second variables, by generating a first and second filtering bitmap. The first filtering bitmap represents a set of values for the second variable for each of a plurality of values of the first variable. The second filtering bitmap represents, associations between frequent values of the second variable, which enables the identification of frequent 2-pattern itemsets. Thus, by performing first logical operations on the frequent 2-pattern itemsets, frequent high order-pattern itemsets may be identified. A max pattern itemset may be identified among the frequent high order-pattern itemsets. As a result, embodiments may mitigate performance and stability problems associated with conventional association rule mining approaches.

Abstract: An apparatus, system, and method is provided to connect precast concrete panels to a structural member. The connector can have a receiving member embedded in a precast concrete panel and can further have an attachment member that selectively interconnects to the receiving member. This attachment member can have a surface that is oriented substantially perpendicular to the precast concrete panel and that receives or supports a structural member such as a floor joist or a second precast concrete panel. The configuration of a protrusion of the attachment member allows for a rapid and secure interconnection with an aperture in the receiving member. A builder can use the connector system described herein to rapidly and securely assemble multiple precast concrete panels to structural members in the construction of, for example, a parking garage or other similar structure.
