Abstract:
The present invention relates to a method of detecting the alteration of the driver of a windows kernel and a system using system module information that is the unalterable information of the windows kernel.The method of detecting the alteration of a windows kernel according to the present invention includes a first step of reading, by an alteration detection driver, information about a name and start and end addresses of a detection target driver from system module information; a second step of extracting a function that is used by a driver object of the detection target driver using the name of the detection target driver; and a third step of determining that the detection target driver has not been altered if an address of the function is a value between the start address and the end address, and determining that the detection target driver has been altered if the address of the function is not a value between the start address and the end address.
Abstract:
An apparatus and a method for transmission encoding a message with space-time turbo code using feedback information of the channel gain or the phase in digital mobile communication system having a plurality of transmit antennas are disclosed.
Abstract:
Disclosed is a method for encoding messages with space-time trellis codes(STTC) and transmitting the encoded messages in communication system provided with at least two transmit antennas and at least one receive antenna. The method comprising generating a codeword by encoding message using STTC; generating a modified codeword by multiplying the codeword by unitary matrix V; and multiplying the modified codeword by weighting matrix W, and then transmitting it through transmit antennas. The weighting matrix W is determined depending on channel information fed back to the transmit antenna from the receive antenna. The unitary matrix V is the value that minimizes the union bound of frame error rate, and is chosen by computer search. Result of a simulation using the method shows that the performance of the STTC is improved over a wide range of feedback channel condition.
Abstract:
There is provided a vacuum cleaner. The vacuum cleaner includes a dust storing part; a compression passage connecting a motor generating a negative pressure to the dust storing part; a flow passage control unit that controls opening and closing of the compression passage; and a compression unit compressing dust stored in the dust storing part when the compression passage is opened.
Abstract:
A supercharger for an internal combustion, diesel engine includes a clutch disc for engaging or disengaging the flywheel of the engine for transmitting power to the transmission and wheels of a vehicle in which the engine is mounted. A blower assembly for the supercharger is fixedly connected to the clutch disc for rotation in unison therewith. The blower includes a cover secured to the clutch disc and a plurality of impeller vanes disposed about its periphery. In operation, when the clutch disc is engaged with the flywheel of the engine, the blower of the supercharger rotates in unison with the clutch plate to draw in air and supply compressed air to the engine to perform the supercharging functions. However, during idling, when the clutch is disengaged, the supercharger blower does not rotate thereby minimizing fuel consumption.

Abstract:
Disclosed are an optical member and a display device including the same. The optical member includes a receiving member; a host in the receiving member; and a plurality of wavelength conversion particles distributed in the host. The receiving member includes a light incident part having a first refractive index; and a light exit part having a second refractive index different from the first refractive index. The optical member improves the optical characteristics by adjusting the refractive indexes of the light incident part and the light exit part.
Abstract:
Disclosed herein are an apparatus and method of performing inter-cell interference coordination in a heterogeneous network. The apparatus includes a reception unit, a determination unit, a generation unit, and a transmission unit. The reception unit receives a modulation and coding scheme (MCS) level from a small cell base station in each frame. The determination unit determines a calculated MCS level based on the MCS level and an interfering signal estimated through probabilistic modeling. The generation unit generates a ratio of subframes, in which data will not be transmitted, to all subframes of a frame based on the MCS level and the calculated MCS level. The transmission unit transmits the ratio and the calculated MCS level to the small cell base station.
