The effect of support material (γ-Al₂O₃, SiO₂, ZrO₂ and AC) on MgO based catalyst was investigated. All catalysts can convert triglycerides into hydrocarbons in diesel range via two parallel pathway: decarboxylation or subsequent cracking reaction. The effect of the addition of CaO and ZrO₂ on MgO supported on SiO₂ and AC was also studied. The addition of CaO and ZrO₂ significantly improved the catalyst activity and stability which gave lower acid values in comparison to the monometallic supported MgO. The addition of CaO lead to the formation of increased lighter hydrocarbons, whereas the addition of ZrO₂ was found to increase the yield in diesel fraction.

component decomposition method based on the spectral line. We first calculate the spectral line of an M-channel image, then using the line, we decompose the image into three components: a single M-channel image and two gray-scale images. By virtue of the decomposition, the noise is concentrated on the two images, thus the algorithm needs to denoise only two grayscale images, regardless of the number of channels. For unmixing, we propose an algorithm that exploits the low-rank local abundance by applying the unclear norm to the abundance matrix for local regions of spatial and abundance domains. In optimization problem, the local abundance regularizer is collaborated with the L2, 1 norm and the total variation.

概要:
The growth of the Internet has led to provide a wide variety of network services such as multimedia services, e-commerce, online banking and trading, social network services, and online games. TCP is still commonly used as reliable
…
data-transmission protocol although network environment for such services has significantly changed as described above. However, TCP has an essential problem to provide real-time and delay-sensitive services, by "reactive" control to recover lost packet. To prevent this problem, the number of retransmissions must be kept as low as possible. One efficient way to prevent packet losses by "proactive" control is to apply a technology called "forward error correction" (FEC). This study aimed to improve TCP performance for real-time and delay-sensitive services. To achieve this, I proposed schemes to apply FEC to the entire TCP operation. The effectiveness of the proposed schemes was demonstrated through simulation evaluations.

The anti-metastasis of α-Mangostin has been found in several researches on cancer cells, but in this study, I found that α-Mangostin also had positive effect on normal cells which were surrounded cancer cells. This finding is important to optimize the conditions of this compound as a chemotherapeutic and chemopreventive agent for cancer treatment. In addition, α-Mangostin changed the mechanical properties which has been proposed to participate in regulation of cell state and fate. The mechanical properies is also play important role in leukocytes, α-Mangostin reduced the cell stiffness followed by induced the cell adhesion and activated leukocytes. These results contribute to complete the whole picture of the biological function of α-Mangostin, and these functions of α-Mangostin are useful for studies on the potential pharmacological principles as well as the preclinical applications of the α-Mangostin.

cturability due to the CMP variability. In analog design, especially, designers are suffering from passing the density checking since there are few useful tools. To tackle this issue, we focus on a transistor-array(TA)-style analog layout, and propose a density optimization algorithm consistent with complicated design rules. Based on TA-style, we introduce a density-aware layout format to explicitly control the layout pattern density, and provide the mathematical optimization approach. Hence, a design flow incorporating our density optimization can drastically reduce the design time with fewer iterations. In a design case of an OPAMP layout in a 65nm CMOS process, the result demonstrates that the proposed approach achieves more than 48× speed-up compared with conventional manual layout, meanwhile, it shows a good circuit performance in the post-layout simulation.

The most accurate water index for delineating the surface area of Ogii Lake was MNDWI-1(R=0.94, p < 0.01). Evaporation from the lake was estimated using the energy-budget method based on historical reanalysis (ERA5) daily data. Total annual evaporation from Ogii Lake increased steadily over the last three decades; comparing to 1989, annual evaporation increased by 20.02, 25.79, and 32.4 mm in 1999, 2009, and 2019, respectively. Comparison result showed that precipitation is not a main part of the water source for Ogii Lake. The result of the estimated water balance between 2016 and 2019 was demonstrated that both surface and groundwater have a considerable influence on Ogii Lake’s water balance. The GWPZs of Ogii Lake Basin was delineated integrating the AHP and MCDM methods. The highest GWPZs was coincided with deepest part of the lake, where the tectonic fault cross Ogii Lake.

creatinine. Ammonia and creatinine are important urinary metabolites in the physiological and pathological aspects associated with kidney disease. Accurate detection of these metabolites from urine or exhaled breath is an importance topic in the medical field as a non-invasive diagnostic method. On the other hand, detection of these compounds in exhaled breath or urine samples are generally troublesome due to their very low concentrations, the complexity of the coexisting (matrix) components contained in the samples, and the high humidity. Sophisticated analyzers are expensive, costly, and time consuming, making it difficult to spread as a general-purpose technology. In order to solve these problems, in this thesis, we researched and developed an optical detection system that can easily and quickly detect the renal biomarker, using optical fiber.

research interests. In addition, recovery of valuable metals together with removal of toxic metals is considered. Among conventional techniques, adsorption technique becomes one of the alternative treatments, due to high efficiency, low cost, and easy operation. In this study, adsorptive separation of heavy metals from aquatic environment was investigated with three main topics. Firstly, adsorptive removal of arsenic was investigated employing two resins CRB05 with N-methyl-D-glucamine group and Lewatit FO36 with FeOOH group. Secondly, reductive adsorption of Cr(VI) was investigated using coal-based activated carbon. Thirdly, selective adsorption of Pb(II) from aqueous solution containing Pb(II), Cu(II), Zn(II), and Cd(II), was investigated, using chelating resin CR11 with iminodiacetic-acid group, goethite, and magnetite.

Moreover, the reduction of TSO42- concentration showed the relatively large decreasing amount of inorganic aerosol mass concentration (IAM) and the significant increase of aerosol pH, with corresponding fitting equations of yIAM = -12.89x + 10.47x2, and ypH = 0.97x + 0.54x2, respectively (yIAM, ypH, and x presents the IAM variation [μg·m-3], inorganic aerosol pH variation [dimensionless], and concentration reduction ratio (CRR)/100 [dimensionless]). In addition, the exposure of particle-bound heavy metals could exert significant influences on the ecological environment and children’s health; control of ship emissions should be given priority. Overall, our results clearly demonstrate the characteristics of atmospheric particles, providing policy makers with basic and effective ideas for mitigating particle pollution from two perspectives of air quality and human health.

…
ncrease of cooling energy demands. Focusing on Jakarta, Indonesia’s capital city, proposed shading devices were simulated to show their performance to improve daylight and reduce cooling energy consumption. The shading design is inspired by Japanese koshi, but using L-shaped aluminum profiles as mini-louvers. The environmental benefit is obtained from improving daylight condition and saving the cooling energy. Several simulations were executed. Attaching L-shaped mini-louvers at the window can lead the Useful Daylight Illuminance (UDI) to be more than 90. The comparison between electric saving and application cost shows the simple payback period of the simulated sun shadings. Placing the 15 mm × 15 mm L-shaped mini-louvers in the east and west can meet the simple payback period less than a year in both residential and office.

概要:
The indoor thermal environment in the hot summer and cold winter (HSCW) region is the worst in China. Residences in this region are mainly outside-insulated and perform poorly under the intermittent cooling/heating modes in individual
…
rooms. Interior insulation is proposed to be a more suitable way under such usage patterns. Bedrooms of a high-rise residential unit in Chengdu, a typical city in the HSCW region, were retrofitted with interior insulation. Comparative field experiments were performed during the cooling and heating seasons, and the main conclusion can be summarized as follows. Firstly, the retrofitted south bedroom had a good energy-saving effect both in summer and winter. Secondly, the indoor temperature was better controlled in the retrofitted south bedroom, closer to the setpoint. And temperature difference was smaller both horizontally and vertically. Thirdly, the retrofitted south bedroom outperformed the north one in terms of both energy-saving rate and indoor thermal environment.
