20150245068 | TSM RATE-DISTORTION OPTIMIZING METHOD, ENCODING METHOD AND DEVICE USING THE SAME, AND APPARATUS FOR PROCESSING PICTURE - Provided are a TSM rate-distortion optimizing method, encoding method and device using the same, and an image processing apparatus. The TSM rate-distortion optimizing method includes calculating a cost of each intra-prediction mode with respect to a block to be encoded using a sum of absolute values of differences between original pixels and reference pixels; selecting candidate modes of the intra-prediction modes according to the cost; calculating a TSM (Transform Skip Mode)-based rate-distortion cost according to the candidate modes; and comparing rate-distortion costs of the candidate modes and deciding a mode to be used for intra-prediction of the block. | 08-27-2015 |

20090011224 | FORMATION OF LARGE ARRAYS OF ZINC OXIDE NANOSTRUCTURES USING ELECTRODEPOSITION - In an aqueous solution of a zinc salt, counter, reference and working electrodes are placed, and an electric potential is applied across the working and reference electrodes. A gas including oxygen and an inert gas is introduced into the aqueous solution. Responsive to these conditions an array of zinc oxide nanostructures grows on a conductive nucleation plate that is a part of the working electrode. The nanostructures have sharp tips, have a more efficient electron emissivity than nanorods made from other materials, and can be used in fabricating field emission lamps and displays. | 01-08-2009 |

20160064249 | LOCAL DOPING OF TWO-DIMENSIONAL MATERIALS - This disclosure provides systems, methods, and apparatus related to locally doping two-dimensional (2D) materials. In one aspect, an assembly including a substrate, a first insulator disposed on the substrate, a second insulator disposed on the first insulator, and a 2D material disposed on the second insulator is formed. A first voltage is applied between the 2D material and the substrate. With the first voltage applied between the 2D material and the substrate, a second voltage is applied between the 2D material and a probe positioned proximate the 2D material. The second voltage between the 2D material and the probe is removed. The first voltage between the 2D material and the substrate is removed. A portion of the 2D material proximate the probe when the second voltage was applied has a different electron density compared to a remainder of the 2D material. | 03-03-2016 |
