        Due to growth of electronics and control devices, automation and situational awareness systems have been applied by automobile. Vision systems with the introduction of unmanned system were being actively developed. In this paper, the distortion in the 7-inch LCD screen for the treatment process are divided into Online and Offline processing. Offline processing based on the image signal processing and for generating LUT Online to Offline generated by processing the distortion is applied to the LUT. LUT is applied to distort the image processing in real time, so that distortion correction is made for the purpose of setting.

        This study deals with inorganic Carbon dioxide Capture Utilization (CCU) by using seawater-based industrial wastewater. Industrial wastewater, which contains plenty of cations such as Ca2+ and Mg2+, is considered as a cation source for mineral carbonation. Modeled industrial wastewater was used to study the tendency of mineral carbonation on various condition. Cation concentration of industrial wastewater was modified at various levels and then reacted with fully CO2- absorbed 30wt.% monoethanolamine (MEA) solution. A metal carbonate precipitated as a result of the reaction, and the same experiment was performed with 1/3, 2/3 CO2-absorbed MEA solution to study the tendency of carbonation under different CO3 2− conditions. The amount of precipitate was increased proportionally to the cation concentration and the amount of absorbed CO2. Most of the precipitate was calcium carbonate (CaCO3), although other metal carbonates were also formed. Most of the CaCO3 was found in calcite form, but vaterite and aragonite were also formed under specific conditions. Based on the experimental results, we conclude that by controlling the concentration of cations and CO3 2−, we were able to optimize mineral carbonation conditions. We also noticed that low CO3 2− concentration in MEA solutions is advantageous for producing high quality calcium carbonate crystals. Inductively Coupled Plasma (ICP), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) analyses were performed to analyze the precipitate.

        Municipal solid waste incinerator (MSWI) fly ash was used for accelerated carbonation via bubbling of gaseous carbon dioxide (CO2) after treatment with sodium hydroxide (NaOH). The influence of alkaline concentration and volumetric flowrate of CO2 was investigated. Experimental results showed that carbonation reduced the leaching of Cu, Pb, Zn, and Cr. The pH of leachate decreased from around 12 to 10.5. The content of soluble chlorides was also decreased after carbonation. Additionally, the application of accelerated carbonation enhanced the sequestration of CO2 from MSW incineration plants. The TG/DSC analysis indicated that MSWI fly ash sequestrated approximately 185 g CO2/kg waste.
