Abstract: The present disclosure provides a two-stage blade adjusting device for a counter-rotating axial flow fan. A blade adjusting operation shaft is adjusted to drive a pair of bevel gears to transfer power to a threaded pair coaxial with a transmission shaft, the threaded pair transforms rotary motion of the bevel gears into linear motion to push thrust discs in hubs, the blade installation angle of a first impeller is thus adjusted, and a spacer bush transfers the power to adjust the blade installation angle of a second impeller, so that synchronous adjustment of two-stage blade installation angles is realized. The device is simple and compact in structure and low in manufacturing and maintenance cost, and can be widely applied to large, medium and small counter-rotating axial flow fans.

Abstract: There is provided a ventilation apparatus with counter-rotating impellers driven by long shaft, wherein an electric motor and a gearbox are placed outside the air duct by using a long shaft with an internally disposed slim shaft extending therefrom, and are connected with the first stage impeller and second stage impeller inside the air duct by using the long shaft and slim shaft extending therefrom. In this ventilation apparatus with counter-rotating impellers, the components of the ventilation apparatus are placed inside and outside the air duct respectively by using the transmission shaft, which is convenient for maintenance and operation. By remotely arranging the impellers at an axial distance, the hub of the impellers will no longer be affected by an internally disposed electric motor, so as to reduce the ventilation resistance to ventilation. The impellers can be switched between the single impeller rotation and the counter rotation of two impellers.

The first housing comprises a front housing and a rear housing, and a limiting groove is disposed in an inner wall of the first housing. The tip is fixedly connected to one end of the connecting cylinder, and the other end of the connecting cylinder passes through an end-portion through-hole of the front housing.

Abstract: A system and method to generate an improved layout of a data grid in a database environment is provided. The data grid is a clustered in-memory database cache comprising one or more data fabrics, where each data fabric includes multiple in-memory database cache nodes. A data grid advisor capability can be used by application developers and database administrators to evaluate and design the data grid layout so as to optimize performance based on resource constraints and the needs of particular database applications.

Abstract: A passive optical network (PON) system includes at least one optical line terminal (OLT), a plurality of optical network units (ONUs) connected to each OLT, and an OLT management server used to manage the OLT. The OLT management server creates a VLAN access control table in response to a user's request to indicate a VID translation relation among different VLAN identifiers (VIDs) and sends a VID translation relation described in the VLAN access control table to the OLT, and the OLT creates a VLAN translation table indicating a correspondence relation between a source VID and a destination VID, which are waiting for translation, based on the received VID translation relation. If the OLT determines that a VID included in a received frame must be translated based on the VLAN translation table, the OLT references the VLAN translation table to translate the VID included in the received frame to a corresponding destination VID.

Abstract: Methods, systems, and computer program products for tuning query execution performance in a database management system are described. In an embodiment, query performance issues of chosen database operational logic in a database management system are identified with an external utility provided for use on top of the database management system. The identified query performance issues are resolved selectively in the database management system without modifying the chosen database operational logic.

Abstract: A Bacillus strain has a chromosome with the following modifications: a mutation of a spoIIIE gene which blocks transfer of the prespore chromosome; a mutation which prevents loss of SpoOJ function from blocking sporulation; a first reporter gene dependent on &sgr;F factor and placed at a location where impaired SpoOJ function leads to increased trapping in the prespore; and a second reporter gene having a promoter which is dependent on &sgr;F factor and where impaired SpoOJ function leads to reduced trapping in the prespore. The strain is useful in a method of screening for putative antibiotics.

Abstract: A three-terminal non-volatile ferroelectric/superconductor thin film field effect transistor (FsuFET). The FSuFET is used as a non-volatile memory storage device that provides two static states and four transient states. The FSuFET includes a superconducting film epitaxially grown on a substrate layer. A ferroelectric thin film is then epitaxially grown on the superconducting layer to form the gate of the FSuFET. A drain electrode and a source electrode are then contacted to the superconducting film on either side of the ferroelectric gate. In static mode, the two polarization states of the ferroelectric gate correspond to the binary "0" and "1" states, which are switched by applying a voltage pulse of sufficient magnitude. In transient mode, the four states depend upon the polarization state of the ferroelectric gate and the conductive state (superconducting or non-superconducting) of the drain-source channel.
