摘要:
A high speed centrifugal compressor for compressing fluids includes a permanent magnet synchronous motor (PMSM) having a hollow shaft, the being supported on its ends by ball bearing comprising supports. A permanent magnet core is embedded inside the shaft. A stator with a winding is located radially outward of the shaft. The PMSM includes a rotor including at least one impeller secured to the shaft or integrated with the shaft as a single piece. The rotor is a high rigidity rotor providing a bending mode speed of at least 100,000 RPM which advantageously permits implementation of relatively low-cost ball bearing comprising supports.

A draining construction wrap includes a pliable moisture impermeable layer having interior and exterior surfaces. A drainage framework is configured to channel moisture across the exterior surface of the pliable moisture impermeable layer. The drainage framework includes a plurality of support struts. Each of the support struts includes a base strut portion coupled with the exterior surface, a strut support face, and a strut body extending from the base strut portion to the strut support face. A plurality of drain channels are between the support struts. The draining construction wrap includes an installation surface configured for coupling with an outer wall. The installation surface includes the strut support faces of the plurality of support struts. The strut bodies of the plurality of support struts brace the installation surface and the pliable moisture impermeable layer is recessed from the installation surface with a strut gap therebetween.

A pre-coding/decoding method and apparatus for data transmission between a transmitting end and a receiving end is provided. The pre-coding method for data transmission through Time Division Duplexing (TDD) in a mobile communication system includes estimating downlink channel state information based on an uplink sounding signal, and pre-coding a data symbol and a reference signal based on the estimated downlink channel state information.

A method for transmitting signals in a multi-carrier radio transmission system is provided. The method includes a transmission block composed of N consecutive Orthogonal Frequency-Division Multiplexing (OFDM) symbols in a time domain and M consecutive physical sub-carriers in a frequency domain, where N and M are each an integer not less than 1. The method further includes encoding and interleaving data at a transmitting end, transmitting a pilot signal in a frequency area of a pilot stream for transmission of the pilot signal, performing, at the transmitting end, an IFFT operation on the encoded and interleaved data and the pilot signal, and transmitting, at the transmitting end, the data and the pilot signal through at least one antenna after inserting a preamble signal, wherein at least one pilot stream exists at the transmitting end, and wherein at most one pilot signal is transmitted in a group of OFDM symbols.

Provided is a strip-assembled immunochromatographic disc, containing: a base, a lid engaged with the base and a draining piece disposed between the strips on the base and the lid, wherein a sampling opening is disposed on the lid directly facing to the draining piece, and the said sampling opening intercommunicates to a draining groove provided on the inner side of the lid which is formed by a plurality of draining channels; several strip stages are provided on the base with their location and number corresponding to those of the draining channels provided on the lid, and the edge of the draining piece laps to the sample pads of the strips carried on the stage adjacent to one end of the sampling opening. Also provided is a method of performing multiplexed immnochromatographic detection using the strip disc to accomplish the detection of multiple target analytes in one sample in an assay.
摘要:
There is provided at least one isolated antimicrobial peptide, wherein the peptide is a linear analog of hBD3 or a fragment thereof. In particular, there is provided a linear analog of hBD3 wherein the peptide has a reduced cytotoxicity to at least one cell compared to the wild type hBD3.

A method by a Mobile Terminal (MT) for positioning the MT is provided. The method includes requesting a Base Station (BS) to allocate a first transmission time for transmitting a first sounding signal for the MT, receiving the first transmission time from the BS, transmitting the first sounding signal to the BS at the first transmission time, requesting the BS to allocate a second transmission time of a second sounding signal for the MT after the MT moves, receiving the second transmission time from the BS, transmitting the second sounding signal to the BS at the second transmission time, reporting a moving distance moved during the period between the first transmission time and the second transmission time, and receiving a position of the MT determined based on the first sounding signal, the second sounding signal, and the moving distance.
摘要:
A network accessing method includes selecting a group representative dynamically from each machine to machine (M2M) terminal group, wherein terminals in the M2M terminal group not selected as the group representative serve as group members. The method also includes requesting, by the group representative, network access from a base station, and serving, as a group member automatically after entering an idle state or entering another cell. This enables multiple M2M terminals to access a network at the same time while avoiding network access congestion.
