An apparatus and method of reconstructing a three-dimensional (3D) image from two-dimensional (2D) images are disclosed. Three dimensional (3D) data may be reconstructed in an x-ray generation tube at a limited angle, and repeatedly updated for each pixel. A median from among each pixel of reconstruction data may be selected. Backprojecting may be performed using a search direction weight calculated using a reprojection image and residual image. A 3D image satisfying a Level 1 (L1) norm fidelity and sparsity constraint of the reconstruction data may be reconstructed.

Disclosed is a perfume composition having a fragrance like that of green tea flowers. The perfume composition contains artificial synthetic substance trans-4,8-dimethyl-1,3,7-nonatriene or lilac alcohol, in addition to the main fragrant components of green tea flowers, analyzed by an SPME method or a solvent extraction method, and thus has a fragrance like that of the characteristic fragrance of green tea flowers and, at the same time, has high preference.

摘要:
A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.

A chemical vapor deposition system is provided. In the chemical vapor deposition system, an amount of a first reaction gas remaining between a process chamber and a first reaction gas supplying unit is exhausted to a vacuum pump, and an amount of a second reaction gas remaining between the process chamber and a second reaction gas supplying unit is exhausted to an absorption pump. In this system, at least two reaction gases which react with each other in the process chamber are separately exhausted, and thus a reaction byproduct is not generated due to a reaction of the gases remaining in the supply lines. Thus, exhaust lines or pumps can be prevented from being damaged due to the reaction byproduct.

摘要:
Wireless channel capacity of a digital enhanced cordless telecommunication (DECT) base station may be expanded by selecting an unused timeslot from a plurality of timeslots of a downlink channel. A dummy bearer may be created in a corresponding timeslot and it may be determined whether a traffic bearer is created in an unused timeslot. If so, the dummy bearer may be removed, and dummy bearer information may be periodically transmitted to a handset through a traffic bearer on every frame. Dummy bearer information may be inserted into a header of the traffic bearer, and the previously created dummy bearer may be removed after the insertion is completed. Usage of the timeslot occupied by the dummy bearer may be changed to voice communication. When the traffic bearer is released, the dummy bearer may be re-created, and dummy bearer information may be periodically transmitted to the handset through the re-created dummy bearer on every frame.
