Abstract: An apparatus and a method for adaptive de-interlacing using a Takagi-Sugeno fuzzy model are provided to acquire the interpolation image of good image quality irrespective of the edge property or motion property of an image and apply an interpolation method selectively to the image in consideration of complexity according to the motion property of the image, thereby improving objective and subjective image quality and an algorithm calculating rate. A maximum difference coefficient calculator(110) calculates the first maximum difference coefficient of a difference value between the maximum value and the minimum value out of the pixel values of first pixels selected in a special axis window set to a current frame including a interpolation target pixel, and calculates the second maximum difference coefficient of a difference value between the maximum value and the minimum value out of the pixel values of second pixels selected in a temporal axis window set to reference frames near on the temporal axis for the current frame including the interpolation target pixel. A membership value calculator(120) calculates a first membership value for each of edge direction angles which the first pixels form in the spatial axis window on the basis of the first maximum difference coefficient, and calculates a second membership value for each of edge direction angles which the second pixels form in the temporal axis window on the basis of the second maximum difference coefficient. An edge direction angle determining unit(130) determines an edge direction angle corresponding to the maximum membership value out of the first membership value and the second membership value as the maximum edge direction angle. A first interpolation unit(170) interpolates the interpolation target pixel by the average pixel value of pixels positioned on the maximum edge direction angle in the window to which pixels corresponding to the maximum membership value belong.

An apparatus for removing fluorine and calcium in water comprises: a first fluorine removal tank(11) into which influent(20) containing fluorine flows, which adds a calcium salt(24) and a calcite slurry to the influent, and which reacts fluorine in the influent with calcium contained in the calcium salt and the calcite slurry to form a colloidal calcium fluoride; a calcium removal tank(12) into which effluent from the first fluorine removal tank and activated calcite flow, which adds a calcium removal agent(25) to the effluent and the activated calcite, and which reacts calcium in the effluent with the calcium removal agent to form calcite and grow the calcite in a state that the formed calcite is adhered to an activated calcite seed; a solid-liquid separation tank(13) into which effluent flows from the calcium removal tank, and which separates calcium fluoride and calcite from the effluent; a first coagulation tank(14) into which effluent flows from the solid-liquid separation tank, which adds a polymer material(26) to the effluent, and which coagulates the calcium fluoride by means of the polymer material; a first settling tank(15) into which effluent flows from the first coagulation tank, and which subjects the effluent to a solid-liquid separation to settle calcium fluoride in the effluent; a seed activation tank(10) into which the calcite separated in the solid-liquid separation tank flows, and which activates the calcite to transfer the activated calcite to the calcium removal tank; and a cavitation generator(19) connected to the seed activation tank to micronize and spheroidize the calcite of the seed activation tank. Further, the cavitation generator generates cavitation by a spray method in water.

Title: Bridge drainpipe connector and method for connecting drainpipe using the same

Abstract: A drainpipe connector for a bridge and a drainpipe connecting method using the drainpipe connector are provided to prevent the outflow of leaking water by winding water leakage prevention rubber rings on two ends of drainpipes, covering the water leakage prevention rubber rings and two ends of the drainpipes with a rubber packing, and then fastening a coupling band, to separate or couple a drainpipe connector simply for cleaning the inside of a drainpipe, and to have an earthquake-proof function by absorbing the shaking of a connection of drainpipes using a rubber packing and preventing the breakage of a connection of drainpipes. A drainpipe connector(20) for a bridge is formed by installing water leakage prevention rubber rings on two ends of drainpipes(13), inserting the drainpipe wound by the water leakage prevention rubber rings to penetration units formed on two sides of a rubber packing to make the ends of the drainpipe contact with each other in the penetration units, and fastening a coupling band(50) on the rubber packing. A drainpipe connecting method using the drainpipe connector for a bridge comprises the steps of winding water leakage prevention rubber rings made of a stainless steel wire, a stainless steel wire covered with rubber or PVC on two ends of a drainpipe at a certain distance, fastening the water leakage prevention rubber rings to the circumference of the drainpipe using a quick fastener, inserting the end of the drainpipe fastened with the water leakage prevention rubber rings to two sides of a penetration unit of a rubber packing to make two ends of the drainpipes adhered closely, thereby to connect the drainpipes with each other, and fastening a coupling band manufactured with PVC, stainless steel or steel to the outside of the rubber packing to cover the rubber packing, and coupling a fastening clip(51) attached to the coupling band to compress the rubber packing from the outside of the rubber packing and to keep the connection of the drainpipes fixed.
