Abstract:
Techniques for end-to-end tracing of database operations in source code for database applications are provided. Source code on the client side is instrumented to measure time spent on selected database operation statements (e.g., queries). The selected database operation statements can be uniquely tagged or identified. Tracing is enabled on the database application on the server side so that a log is produced, where the log includes performance (e.g., time spent) information on database operation statements that are executed. The performance information in the log is correlated to the selected database operation statements so that, among other things, the time spent on the client side and the time spent on the server side can be presented for analysis.

Abstract:
A large machining apparatus for working a substantially planar workpiece such as a metal plate in relation to which a set of work actions, such as machining grooves and holes, is required at one of a number of work zones on or in the workpiece, the apparatus including: a working assembly such as a drop down drill movably mounted on a beam for reciprocal linear movement along a first horizontal axis extending parallel to the longitudinal axis of the workpiece; and an assembly rail movably mounted on the beam at right angles to the beam to carry the working assembly. The apparatus further includes: an immobilizing base mounted on the rail for reciprocal linear movement along the assembly rail in the direction of a second axis and a clamping base mounted on the immobilizing base and adapted to be clamped onto the workpiece to locate the working assembly at a predetermined one of said work zones; and a movable base mounted on the assembly rail for limited reciprocal linear displacement along the assembly rail in the direction of the second axis relative to the immobilizing base. The working assembly is mounted on the movable base to enable limited linear displacement of the working assembly in the second axis direction in the predetermined work zone.
Abstract:
An application programming interface (API) for administering the distribution of software updates on an update service node is presented. The API provides a plurality of interface calls through which an administrator can establish rules by which software updates available to the update service node are distributed.
Abstract:
A method for preparing induced pluripotent stem (iPS) cells, which comprises steps as follows: step 1, introducing one or more stem cell pluripotency factors into somatic cells; step 2, culturing the somatic cells, into which the stem cell pluripotency factor has been introduced in the Step 1, by using medium supplemented with lithium salt; and step 3, identifying and characterizing the induced pluripotent stem cells. Furthermore, there provided a medium for preparing induced pluripotent stem cells, which comprising lithium salt. The medium supplemented with lithium salt is used for efficiently inducing pluripotent stem cells. Lithium salt is able to increase the production efficiency of mouse iPS cells by 5-60 times. The present method for inducing iPS cells is in favor of improving the safety of iPS technique and application of iPS cells in regenerative medicine.
Abstract:
A socket connector includes a socket body, a sliding plate movably mounted upon the socket body, a plurality contacts received in the socket body and the sliding plate, and an actuating mechanism. The actuating mechanism includes a lid moving upwardly and downwardly between a first position away from the socket body and a second position close to the socket body, and a lever having one mating bar with at least a first tab and a second tab to be pressed by the lid so as to push the sliding plate moving.
Abstract:
A piezoelectric patch can be used to repair a defective structure having a plate configuration. The piezoelectric patch can be energized with an applied voltage that is configured to sustain the loading arising from the plate. The applied voltages and electrodes of the patch can be configured based on a numerical model and a finite element method (FEM).

Abstract:
Techniques for providing type (and/or mode) conversion of parameters for software applications are provided. In general, a type conversion utility accesses a template that defines type and mode conversions for parameters between different components. The type conversion utility utilizes information stored in the template for that direct how the parameters will be converted. Additionally, techniques are provided for returning output values.
Abstract:
The present invention is intended to protect an industrial wireless communication method based on self-adaptive channel hopping within timeslot, which belongs to industrial wireless communication technology field. Aiming to solving existing problem that wireless devices can not correspondingly self-adaptive channel hopping according to environment changing, a method for making the two communication sides self-generate and execute channel switch when the preferred channel was interfered. The sender will monitor whether the channel is idle within SWTW before sending data through mechanisms such as CCA or non-persistent CSMA. If the channel is still busy till the SWTW times out, the sender will give up sending data and implement channel switching control command by considering this communications channel as interfered. If no packets were received till the RWTW time-outs, the receiver will thinks the communication channel was interfered and automatically implement channel switching control commands. Thus, the receiver will change its backup channel into communication channel. So far, the sender and receiver all independently hop to the backup channel for new communication process after a channel switching cycle. Different time synchronization algorithm will be used in accordance with whether channel switch is carried out or not. The present invention can fully enhance the channel utilization and communication success rate, improve the reliability and real-time of data communication, reduce additional network load by means of reduced retransmission, and perfectly satisfy the requirement of industrial wireless application.
