Perancangan Buku Panduan Menggambar Karakter “Naga Bonbon” sebagai Maskot Studio Bonbin
No full textA mascot is the identity of a product, organization, or company, a good mascot is one that has uniqueness and characteristics that can directly represent the product or organization to the audience. Bonbin Studio has a mascot named Naga Bonbon. Naga Bonbon's character is widely used and illustrated in the context of promotional activities through social media. Each illustrator has its own characteristics and different drawing art style, this can cause the Naga Bonbon Character to have no consistency in style, shape, size, and colors. To overcome this, the author took an initiative to design a "Naga Bonbon" Character Drawing Guidebook as the mascot of Bonbin Studio, this title was chosen by the author because this guidebook contains instructions for drawing the Naga Bonbon character which aims to make it easier for illustrators in Bonbin Studio while creating the Naga Bonbon characters in accordance with the original form and has a consistent style, shape, size, and colors. This guidebook can also help new illustrators to understand and create a Naga Bonbon character easier. While designing this guidebook, the author will use qualitative research methods, this method is intended so the results of the guidebook can be well received and understood by the illustrators or the audience
Research project work plan for performance of high-strength steel reinforcement in shear friction applications
No full textThe use of high strength steel reinforcement has the potential to provide economic and constructability benefits when used in reinforced concrete structures. Current design provisions limit the nominal yield strength of reinforcing steel bars to 60 ksi (420 MPa) for many bridge design applications. This report presents results from a laboratory testing program designed to evaluate the performance of concrete interface shear reinforced with ASTM A706 Grade 60 (420 MPa), ASTM A706 Grade 80 (550 MPa), ASTM A615 Grade 100 (690 MPa), and ASTM A1035 Grade 120 (830 MPa) reinforcing steel bars. Results are reported on the influence of reinforcing steel bar size, reinforcing steel bar spacing, shear interface surface preparation, and nominal concrete strength on shear friction performance. This report provides a summary of previous research regarding shear friction theory, a description of the test specimen design, and an overview of the materials used. Results indicate that using high-strength steel reinforcing bars did not have a significant impact on the peak loads reached, however they did allow for the development of greater post-peak sustained loads due to dowel action in the post-peak stage of the test specimen responses. Significant variation was observed when analyzing the effect of surface preparation. Additionally, in some cases, an exposed aggregate surface preparation enhanced the aggregate interlock and allowed it to contribute to the post-peak shear capacity. Overall, the results presented indicate that an increase in allowable nominal yield strength to 80 ksi (550 MPa) maintains a conservative design per AASHTO and ACI 318-14 code provisions.Final Report -- Appendix A.

No full textEvaluating Landsat 8 evapotranspiration for water use mapping in the Colorado River Basin
No full textAbstractEvapotranspiration (ET) mapping at the Landsat spatial resolution (100m) is essential to fully understand water use and water availability at the field scale. Water use estimates in the Colorado River Basin (CRB), which has diverse ecosystems and complex hydro-climatic regions, will be helpful to water planners and managers. Availability of Landsat 8 images, starting in 2013, provides the opportunity to map ET in the CRB to assess spatial distribution and patterns of water use. The Operational Simplified Surface Energy Balance (SSEBop) model was used with 528 Landsat 8 images to create seamless monthly and annual ET estimates at the inherent 100m thermal band resolution. Annual ET values were summarized by land use/land cover classes. Croplands were the largest consumer of “blue” water while shrublands consumed the most “green” water. Validation using eddy covariance (EC) flux towers and water balance approaches showed good accuracy levels with R2 ranging from 0.74 to 0.95 and the Nash–Sutcliffe model efficiency coefficient ranging from 0.66 to 0.91. The root mean square error (and percent bias) ranged from 0.48mm (13%) to 0.60mm (22%) for daily (days of satellite overpass) ET and from 7.75mm (2%) to 13.04mm (35%) for monthly ET. The spatial and temporal distribution of ET indicates the utility of Landsat 8 for providing important information about ET dynamics across the landscape. Annual crop water use was estimated for five selected irrigation districts in the Lower CRB where annual ET per district ranged between 681mm to 772mm. Annual ET by crop type over the Maricopa Stanfield irrigation district ranged from a low of 384mm for durum wheat to a high of 990mm for alfalfa fields. A rainfall analysis over the five districts suggested that, on average, 69% of the annual ET was met by irrigation. Although the enhanced cloud-masking capability of Landsat 8 based on the cirrus band and utilization of the Fmask algorithm improved the removal of contaminated pixels, the ability to reliably estimate ET over clouded areas remains an important challenge. Overall, the performance of Landsat 8 based ET compared to available EC datasets and water balance estimates for a complex basin such as the CRB demonstrates the potential of using Landsat 8 for annual water use estimation at a national scale. Future efforts will focus on (a) use of consistent methodology across years, (b) integration of multiple sensors to maximize images used, and (c) employing cloud-computing platforms for large scale processing capabilities
Design, Synthesis, Characterization of Geminal Bisphosphonates and Bioactivity Evaluation
No full textCancer is a deadly disease evading all human efforts to understand its etiology, prevention, and cure. In cancer, chronic myelogenous leukemia is one type. It is also known as chronic myeloid leukemia. It is a malignant cancer of the myeloid line of cells in the bone marrow that results in the uncontrolled growth of white blood cells in the bone marrow, bloodstream, and body tissues. Colorectal cancer is another type of cancer that occurs in the colon or rectum. Sometimes it is called colon cancer. Management of these cancers is highly difficult. In persuasion of our goal to synthesize cancer active compounds, the author accomplished the synthesis of substituted amino methylene bisphosphonates (3a-j) and studied their antitumor activity. © 2020 Author(s)
On the Downscaling of Actual Evapotranspiration Maps Based on Combination of MODIS and Landsat-Based Actual Evapotranspiration Estimates
No full textDownscaling is one of the important ways of utilizing the combined benefits of the high temporal resolution of Moderate Resolution Imaging Spectroradiometer (MODIS) images and fine spatial resolution of Landsat images. We have evaluated the output regression with intercept method and developed the Linear with Zero Intercept (LinZI) method for downscaling MODIS-based monthly actual evapotranspiration (AET) maps to the Landsat-scale monthly AET maps for the Colorado River Basin for 2010. We used the 8-day MODIS land surface temperature product (MOD11A2) and 328 cloud-free Landsat images for computing AET maps and downscaling. The regression with intercept method does have limitations in downscaling if the slope and intercept are computed over a large area. A good agreement was obtained between downscaled monthly AET using the LinZI method and the eddy covariance measurements from seven flux sites within the Colorado River Basin. The mean bias ranged from −16 mm (underestimation) to 22 mm (overestimation) per month, and the coefficient of determination varied from 0.52 to 0.88. Some discrepancies between measured and downscaled monthly AET at two flux sites were found to be due to the prevailing flux footprint. A reasonable comparison was also obtained between downscaled monthly AET using LinZI method and the gridded FLUXNET dataset. The downscaled monthly AET nicely captured the temporal variation in sampled land cover classes. The proposed LinZI method can be used at finer temporal resolution (such as 8 days) with further evaluation. The proposed downscaling method will be very useful in advancing the application of remotely sensed images in water resources planning and management
Actual Evapotranspiration (Water Use) Assessment of the Colorado River Basin at the Landsat Resolution Using the Operational Simplified Surface Energy Balance Model
No full textAccurately estimating consumptive water use in the Colorado River Basin (CRB) is important for assessing and managing limited water resources in the basin. Increasing water demand from various sectors may threaten long-term sustainability of the water supply in the arid southwestern United States. We have developed a first-ever basin-wide actual evapotranspiration (ETa) map of the CRB at the Landsat scale for water use assessment at the field level. We used the operational Simplified Surface Energy Balance (SSEBop) model for estimating ETa using 328 cloud-free Landsat images acquired during 2010. Our results show that cropland had the highest ETa among all land cover classes except for water. Validation using eddy covariance measured ETa showed that the SSEBop model nicely captured the variability in annual ETa with an overall R2 of 0.78 and a mean bias error of about 10%. Comparison with water balance-based ETa showed good agreement (R2 = 0.85) at the sub-basin level. Though there was good correlation (R2 = 0.79) between Moderate Resolution Imaging Spectroradiometer (MODIS)-based ETa (1 km spatial resolution) and Landsat-based ETa (30 m spatial resolution), the spatial distribution of MODIS-based ETa was not suitable for water use assessment at the field level. In contrast, Landsat-based ETa has good potential to be used at the field level for water management. With further validation using multiple years and sites, our methodology can be applied for regular production of ETa maps of larger areas such as the conterminous United States
