摘要:
An automotive vehicle front structure includes upper and lower siderails and a structural link extending from the upper and lower siderails, with the structural link having a pivotable connection to the upper siderail and a rigid connection to the lower siderail, such that energy absorption provided by the structure may be tailored by varying the character of the joint between the structural link and the upper siderail.
摘要:
The present invention relates to a trifunctional catalyst used in catalytic cracking device in petroleum refining industry and a method for preparing the same. The trifunctional catalyst of the invention comprises absorbent, cerium dioxide and vanadium pentoxide acting as oxidative catalyst and cerium oxyfluoride acting as structural promoter. The oxidative catalyst and structural promoter are dispersed over the absorbent. The absorbent is spinel-based composite oxides having a general formula of MgAl2-xFexO4.yMgO, where the x is 0.01-0.5 and y is 0.2-1.2. In the trifunctional catalyst, the raw material for forming the chemical compound containing rare-earth cerium is hamartite powder. The method for preparing the trifunctional catalyst of the invention is shown as follows: the components relating to the preparation of the finished product are dissolved or dispersed into liquid materials; then the trifunctional catalyst is obtained after the mixing, drying and calcining of such liquid materials. The trifunctional catalyst of the invention is used for highly efficient absorption and desorption of sulfoxides contained in the catalytic cracking flue gas regenerated in the process of petroleum refining, the combustion promoting of carbon monoxide and the reduction of nitrogen oxides. Furthermore, the method for preparing such trifunctional catalyst is featured for its lower cost.

摘要:
Data is stored by utilizing a first operating mode and a second operating mode. In one embodiment, in the first operating mode, a continuous replication method is utilized to store data on a primary storage system and to generate a backup version of the data on a backup storage system. While data is being stored in accordance with the first operating mode, one or more activities performed by the data storage system(s) are monitored. As long as the monitored activity or activities display a first status, the first operating mode is maintained. If the monitored activity or activities display a change in status, the first operating mode is suspended, and data is stored pursuant to the second operating mode. In one embodiment, in the second operating mode, a delta replication method is utilized to store data on the primary storage system and to back up the data on the backup storage system.
摘要:
The method traverses a storage device, performing read operations on each allocated data block on the device, recording each I/O access to the device resulting from the read operations, and identifying the data blocks involved in each I/O access to determine which blocks contain valid data. The data blocks that contain valid data are then replicated.

摘要:
A deflector is attached to a sub-frame in the front end of a vehicle that rotates the front end of the vehicle in the event the vehicle contacts an object outboard of the sub-frame. The deflector has a deflection beam that is supported on an outboard end by a reaction leg. The reaction leg is backed by an attachment leg that is secured in a parallel orientation to a part of the sub-frame.

The vehicle roof support pillar is provided which includes a pillar inner panel, a pillar outer panel and a unitary closed-section reinforcement member. The unitary closed-section reinforcement member is disposed entirely within a chamber defined by the pillar inner panel and the pillar outer panel. The unitary closed-section reinforcement member includes an upper area and a lower area. The lower area of the unitary close-section reinforcement member has an increasing cross-section below the buckling line. The pillar inner panel includes upper and lower ends. The lower inner end has a greater width relative to the upper inner end. The pillar outer panel also has a progressively increasing width relative to the upper outer end.
摘要:
In accordance with one example, a method for comparing data units is disclosed comprising generating a first digest representing a first data unit stored in a first memory. A first encoded value is generated based, at least in part, on the first digest and a predetermined value. A second digest representing a second data unit stored in a second memory different from the first memory, is generated. A second encoded value is derived based, at least in part, on the second digest and the predetermined value. It is determined whether the first data unit and the second data unit are the same based, at least in part, on the first digest, the first predetermined value, the first encoded value, and the second digest, by first processor. If the second data unit is not the same as the first data unit, the first data unit is stored in the second memory.
摘要:
A method and apparatus for delivering precursor materials to a processing chamber is described. The apparatus includes a gas distribution assembly having multiple gas delivery zones. Each zone may include a plenum having an inlet for receiving a precursor gas and at least one source of non-thermal energy, such as an infrared light source. The at least one source of non-thermal energy is may be varied to control the intensity of wavelengths from the infrared light source.
摘要:
In one example, an apparatus is provided to store data in one or more data storage systems by selecting from among at least a first operating mode and a delta replication operating mode. The apparatus comprises a means for storing data pursuant to the first operating mode and a means for ascertaining a first status of a criterion pertaining to an activity performed by the one or more data storage systems while operating in the first operating mode. The apparatus further comprises a means for detecting a change in the criterion to a second status, and a means for storing data pursuant to the delta replication operating mode in response to the change.
