A system for measuring the three-dimensional shape of a transparent thin film using an acousto-optic tunable filter. The system can independently obtain thickness information and shape information about a measurement object having a patterned structure through independent measurements by modes according to whether a blocking plate selectively blocks white light irradiated on a reference mirror plane or not. According to the system for measuring the three-dimensional shape of a transparent thin film using an acousto-optic tunable filter of the present invention, thickness information and shape information about a measurement object including a thin film can be independently measured in two different measurement modes according to whether the blocking plate blocks white light or not, so that three-dimensional shape information of the measurement object can be obtained rapidly.

Provided are a method and apparatus for securely distributing digital content. According to the method and apparatus, content is securely transmitted to users who have a right of use content regardless of the reliability of a content distributor, thereby allowing the users to efficiently use content. For example, even if an unauthorized third party changes a list of content users by deleting a user who has a right to use content from the list or adding a user who has no right to use content to the list, such an unauthorized change can be easily detected in real time, thereby securely protecting the list. Accordingly, it is possible to securely distribute and use digital content regardless of a content distributor.

In a method and system for controllable electrostatic-directed deposition of nanoparticles from the gas phase on a substrate patterned to have p-n junction(s), a bias electrical field is reversely applied to the p-n junction, so that uni-polarly charged nanoparticles are laterally confined on the substrate by a balance of electrostatic, van der Waals and image forces and are deposited on a respective p-doped or n-doped regions of the p-n junction when the applied electric field reaches a predetermined strength. The novel controllable deposition of nanoparticles employs commonly used substrate architectures for the patterning of an electric field attracting or repelling nanoparticles to the substrates and offers the opportunity to create a variety of sophisticated electric field patterns which may be used to direct particles with greater precision.

Provided is a method for forming a rate compatible code using high dimensional product codes and a computer-readable recording medium for recording a program that implements the program. The rate compatible code, which can provide various encoding rates, is formed by discriminating parity blocks and determining a punctured pattern for each parity block, m being more than two. The method includes the steps of: a) forming an m dimensional product code by using a systematic block code; b) dividing the m dimensional product code into an information block and 2m-1 parity blocks; c) allocating indices to the divided blocks of the information block and 2m-1 parity blocks; d) finding all combinations of the information block and the parity blocks which are adjacent to the information block; e) estimating a first weighting factor of w1 for the all combinations; f) if there are first combinations having the same weighting factor w1, estimating a second weighting factor of w2 for the first combinations having the same weighting factor w1 as second combinations; g) selecting a combination having largest weighting factor among the second combinations having the second weighting factor w2; and h) forming rate compatible codes by using the selected combinations based on the w1 and w2.

The invention relates to a serrated cutting tip and a serrated cutting tool having the cutting attached thereto capable of working a work piece at a fixed workability. The cutting tip includes a bond layer, which has super abrasive particles contained therein and grooves formed on a face which is in contact with the work piece, and a blank layer for strongly supporting the bond layer, by which a working plane of the cutting tip contacting the work piece is uniformly maintained during working use and debris can be readily discharged. As a result, workability is improved and lifetime is prolonged.
