摘要:
Scalable empirical testing of media file playback utilizes test hooks in each media player to support simulated human interaction and playback monitoring. A media crawler catalogs media files accumulated in a media file database to create a wordlist. One or more scalable instances of media tester accesses the wordlist to select items of work linked to media files. Work items and/or operating modes of media tester specify test parameters such as performance profiles or further define testing such as specifying repetitious playback on one or more media players. Media files are downloaded to and played by a scalable number of media players. Playback performance is monitored, analyzed and reported. Failure reports are accompanied by instructions to reproduce failures and cross-references to content or source code in media files. Failures can be audited by additional work items for follow-up testing.

An advanced treatment method of feed water by combination of metal zinc and ozone is provided. The advanced treatment method of feed water comprises putting metal zinc into an ozone contact reactor, adding water to be treated into the reactor at a flow rate of 1-50 m/h, at the same time, introducing ozone into the water such that the ozone, the metal zinc and the water can be contacted with each other fully. The hydraulic retention time of the water to be treated in the reactor is 1-200 min. The amount of the ozone which is introduced into the water to be treated is 0.1-100 mg per liter water. During the water treatment process of the invention, the metal ions cannot be lost, the secondary pollution cannot be caused, and the preparation technology is simple with low cost and good treatment effect.

An automatic convey device adapted for pushing and grouping a plurality of connectors includes a frame assembly, a holding module and a feeding module disposed on the frame assembly respectively. The holding module has a plurality of positioning units for positioning the connectors. The feeding module includes a power unit, a sliding unit disposed on the frame assembly, a plurality of pushing units and a grouping unit mounted to the sliding unit respectively. The pushing units are capable of repeatedly pushing the respective connectors move forward until the connectors are positioned by the positioning units and then move backward for repeating the last action to push the next connectors forward. The grouping unit is capable of repeating the action of pushing forward the connector positioned by the forward positioning unit and capable of being controlled by the power unit to disconnect with or connect with and push the corresponding connectors.
摘要:
A method and system for providing asymmetric modes of operation in multi-carrier wireless communication systems. A method may assign a long code mask (LCM) to an information channel associated with a plurality of forward link carriers to transmit data from an access network to an access terminal; and multiplex the information channel on a reverse link carrier. The information channel may include one of data source channel (DSC), data rate control (DRC) and acknowledgment (ACK) information, and the multiplexing may be code division multiplexing (CDM). The AN may instruct the AT on whether to multiplex the DSC information based on feedback from the AT. The method may further offset the ACK information on the reverse link to reduce the reverse link peak to average, CDM the information channel on an I-branch and on a Q-branch, and transmit the code division multiplexed information channel on the reverse link carrier.

Migrating services and clients from a legacy topology to a new topology. A method includes receiving user input selecting a first client managed by a first configuration management system to migrate to a second configuration management system. Dependencies of the first client are determined, including determining services on which the first client depends to function in a topology. The dependencies of the first client including services and their data on which the first client depends to function in a topology are migrated to a second configuration management system or an administrator is alerted to the dependencies of the first client including services and their data on which the first client depends to function in a topology.
摘要:
A new method for preparing a supported catalyst is herein provided. A carbon nanotube structure such as a rigid porous structure is formed from carbon nanotubes. A metal catalyst is then loaded or deposited onto the carbon nanotube structure. The loaded carbon nanotube is preferably ground to powder form.

Identifying a trigger point of at least one OFDM decoder includes correlating a first time-domain sample of the at least one OFDM symbol with a second time-domain sample of the at least one OFDM symbol, processing the first time-domain sample and the second time-domain sample in the first moving average filter to determine a channel impulse response, comparing at least one correlation value of a first biggest path in the channel impulse response and a second biggest path in the channel impulse response, and determining a channel length of the channel impulse response based on a time duration of the channel impulse response. The OFDM decoder includes a first moving average filter and a second moving average filter.

A packing cushion includes a base and a plurality of sidewalls coupled to the base. The plurality of sidewalls interconnect with each other and cooperate with the base to form an accommodating space. A first and second cushion portions protrude from an inner surface of the base in the accommodating space. The first cushion portion has a first inclined surface, the second cushion portion has a second inclined surface. The second inclined surface is parallel to the first inclined surface. A contour defined by the first inclined surface matches with at least a part of an object packed in the packing cushion. When the object is packed in the accommodating space, the first inclined surface contacts with at least a part of the object to provided a first cushioning, and when the object is subjected to impact forces to deform the first cushion portion, the second inclined contacts with the object to provided a second cushion.
