Abstract: A c-axis-oriented HAP thin film synthesized by seeded growth on a palladium hydrogen membrane substrate. An exemplary synthetic process includes electrochemical seeding on the substrate, and secondary and tertiary hydrothermal treatments under conditions that favor growth along c-axes and a-axes in sequence. By adjusting corresponding synthetic conditions, an HAP this film can be grown to a controllable thickness with a dense coverage on the underlying substrate. The thin films have relatively high proton conductivity under hydrogen atmosphere and high temperature conditions. The c-axis oriented films may be integrated into fuel cells for application in the intermediate temperature range of 200-600° C. The electrochemical-hydrothermal deposition technique may be applied to create other oriented crystal materials having optimized properties, useful for separations and catalysis as well as electronic and electrochemical applications, electrochemical membrane reactors, and in chemical sensors.

The drive assembly has a pinion with at least two slots that receive axially extending protrusions of a barrel element. Damping elements in the slots and a spring element absorb rock-back and impact oscillations.

Abstract: A method and apparatus for improving SIP server performance is disclosed. The apparatus comprises an enqueuer for determining whether a request packet entering into the server is a new request or a retransmitted request and its retransmission times and for enqueuing the request packet into different queues based on results of the determining step and a dequeuer for dequeuing the packet in the queues for processing based on a scheduling policy. The apparatus may further include a policy controller for communicating with the server, enqueuer, dequeuer, queues and user, to dynamically and automatically set, or set based on the user's instructions, the scheduling policy, number of different queues, each queue's capacity, scheduling, etc. based on the network and/or server load and/or based on different server applications.

Abstract: A communication server, including a partial parser module, a storage module and a lookup module, is provided. The partial parser module parses some, but not all, strings of a message and generates partial parsed data. The storage module stores pre-parsed data which represents a complete parsing of a message. The lookup module looks for the corresponding pre-parsed data from the storage module, using the partial parsed data. The server sends the message according to at least the corresponding pre-parsed data.

Abstract: A render engine for a spreadsheet application is described. The render engine facilitates the rendering of cell regions containing data that are maintained by both a spreadsheet application (user-defined cell region) and/or a third-party application (application-defined cell region). In particular, an embodiment of the render engine facilitates the repositioning of one or more existing cell regions within a spreadsheet interface, when the insertion of a new cell region is determined to cause a layout conflict with one or more existing cell regions. Repositioning of the existing cell regions is achieved without overwriting any cell information, and without breaking any formulas contained within an affected cell.

Abstract: A mechanism for associating a remote document with an email based on user behaviors is described herein. According to one embodiment, an email context is extracted from a current email being accessed by a user, the email context including one or more attributes representing certain characteristics of the current email. A related context having a list of one or more documents is automatically presented that are related to the current email based on at least one attribute of the email context. The one or more documents are associated with a prior email having certain characteristics that are similar to those represented by at least one attribute of the email context. Other methods and apparatuses are also described.

Abstract: A method and an apparatus of processing Session Initiation Protocol (SIP) messages based on multiple cores. The method comprises: pre-parsing a received SIP message to obtain an identifier of the SIP message; dispatching SIP messages with the same identifier to the same core; and processing, on each core, SIP messages dispatched to the core by using related dedicated resources. The present invention relieves the resource contention and thus improves the utilization efficiency of computing resources of cores.
