  • Publication number: 20120271838
    Abstract: The present invention relates to an algorithm that retrieves only k data elements having the largest (or smallest) key values from a dataset (i.e., top-k results) in a time linearly proportional to the size of the dataset. The proposed method using the algorithm finds the top-k results using a k-sized min (or max) heap structure that maintains candidate elements of the top-k results by scanning all data elements in the dataset only once. In other words, the present invention provides a linear-time top-k sort method that finds top-k results in a time linearly proportional to the size of the dataset (i.e., O(n) time complexity), while conventional sort algorithms for finding top-k results cannot find the top-k results in a time linearly proportional to the size of the dataset (i.e., at least O(n log n) time complexity).

  • Patent number: 8287792
    Abstract: In a method of forming fine patterns, a photocurable coating layer is formed on a substrate. A first surface of a template makes contact with the photocurable coating layer. The first surface of the template includes at least two first patterns having a first dispersion degree of sizes, and at least one portion of the first surface of the template includes a photo attenuation member. A light is irradiated onto the photocurable coating layer through the template to form a cured coating layer including second patterns having a second dispersion degree of sizes. The second patterns are generated from the first patterns and the second dispersion degree is less than the first dispersion degree. The template is separate from the cured coating layer. A size dispersion degree of the patterns used in a nanoimprint lithography process may be adjusted by the light attenuation member, so that the fine patterns may be formed to have an improved size dispersion degree.

  • Patent number: 8155833
    Abstract: The present invention relates to a method for controlling the operation of a compressor for preventing noise that occurs in case of the shortage of refrigerant flow caused by less discharge capacity of the compressor of an air conditioner for a vehicle. The compressor includes a cylinder bore for compressing a refrigerant, a piston inserted into the cylinder bore, a swash plate having a controllable slope with respect to a drive shaft, and a control valve for controlling the slope of the swash plate. The discharge capacity of the compressor is increased if it is determined that vehicle speed and accelerating rate satisfy predetermined conditions. If a low flow rate state of refrigerant of the compressor is predicted, the ECV duty is increased to prevent the compressor from entering the low flow rate state, thereby improving the workability of the compressor and solving the noise problem.
