Abstract: A discrete cosine transform (DCT)-based orthogonal frequency-division multiplexing (OFDM) system is provided with a zero-padding guard interval and MMSE reception. The performance of the DCT-OFDM system with the zero-padding guard interval scheme and the minimum mean-square error (MMSE) receiver over time-varying multipath Rayleigh fading channels is investigated. The results show that employing the proposed DCT-OFDM system rather than the conventional DFT-OFDM system can provide better bit error rate performance in practical systems, by as much as 6 dB in signal-to-noise ratio.

The apparatus comprises a flow mitigating device disposed on the at least one actuator arm, the flow mitigating device comprising at least one surface being inclined with respect to a reference plane of the actuator arm to generate streamwise vortices for interacting with and weakening vortex structures generated at a trailing edge of the actuator arm during spinning of the hard disk.

Abstract: A method to remove ringing artifacts from locations near dominant edges of an image reconstructed after compression. The image is decomposed into blocks small enough so that each would contain only one significant edge. A significant edge is tested as to whether it is a dominant edge of the image. If there is no dominant edge, the block is not processed. In the remaining blocks, the exact pixels that include the dominant edges are output without filtering. The direction of the dominant edges is inferred, and then the remaining pixels are filtered with a directional de-ringing filter. The de-ringing filter has a main direction that is perpendicular with the direction of the edge, and thus also with an inherent direction of the ringing artifacts.

Abstract: The present invention discloses a method of constructing a modular framing system where orthogonal frames are arranged adjacent to one another with their corresponding edges positioned next to one another. Each frame is formed from two horizontal and two vertical frame elements. A plurality of locks is inter-disposed between the adjacent vertical frame elements, each with a frame slot. At least two locks are double-locking type, one inter-disposed between the top sections of the vertical frame elements and the other between the bottom sections of the vertical frame elements. A plurality of locks is single-locking type, which is equi-distantly installed along the length of one vertical frame element in between the two double locks. The double locks lock both adjacent vertical frame elements. One side of the single locks lock only one vertical frame element and the other side inserts into the frame slot of the adjacent vertical frame element.
