<![CDATA[Hydrological design, planning and design of flood mitigation structures require detailed knowledge of the characteristics of the flood event, i.e. peaks, volumes, occurrence times and duration. In addition to the uncertainty associated with the occurrence in both space and time, these events may often have a correlation of varying strengths. The literature study interestingly reveals that the majority of studies are based on a univariate approach rather than a more realistic approach that recognizes the multivariate nature of the underlying phenomenology. Therefore, the main objective of this study is to revisit the topic of sizing of flood events in terms of their frequency of occurrence using the ‘Copula’ based bivariate approach to analyze the joint distributions of correlated flood variables with a special focus on Ribb sub basin, Upper Blue Nile (Ethiopia) as the case study. The methodology was applied to flood attributes, i.e. flood peaks and volume generation from partial duration series (PDS) by applying run theory. The Joint Cumulative Distribution Function, the Conditional Cumulative Distribution Function and the associated Return Periods can be easily achieved based on the bivariate distribution of the copula and compared to the univariate analysis.]]>

<![CDATA[The physical and aerodynamic properties of black and white sesame were determined at Moisture Content(MC%) range of 8.5 – 30.6%(d.b).The major, minor, intermediate, arithmetic mean, geometric mean diameters and sphericity, projected area of the two varieties were 2.96 – 3.94mm, 1.47 -2.40mm,0.54 -1.26mm,1.66 – 2.50mm, 0.78 - 3.66mm and 26.53 – 93.45, 1.91 – 42.08mm2 respectively.The increase in MC resulted decrease in true density from 1038.61 – 994.93 kg/mm2 and 1039.61 – 998.47 kg/mm2 for white and black sesame seed respectively.The terminal velocity of white sesame seed ranged from 3.12 – 7.82m/s while black sesame seed ranged from 3.16 – 7.94m/s at MC range of 8.5 – 306% (d.b).The drag coefficient were 3.750.31 and 2.26 – 0.23 for white and black sesame seed respectively as MC ranged from 8.5 – 30.6% (d.b) while Reynold number varied from 2363.9 – 23067.3 and 3401.5 – 15121.6 for white and black sesame seed respectively at MC range of 8.5 - 30.6% (d.b).The properties of sesame seed determined varied significantly with variety and MC.This findings are the prerequisite in the design and selection of sesame seed separating machine. A pneumatic separator can be designed with provision for effective separation of undesired light material with average terminal velocity below 5.17m/s and 5.67m/s for white and black sesame seeds respectively.]]>

<![CDATA[The increasing growth of residential construction, as well as construction waste is also increasing, including tile roof waste. So this study will process the tile fragments or waste to mix concrete as a substitute for coarse aggregate and fly ash as a partial substitution of cement for compressive strength. The purpose of this study was to determine the effect on slump, water absorption, density, and compressive strength of concrete. The method used in this research is experimental by conducting a trial mix which is carried out at the Concrete Laboratory of DSP - PT. Duta Sarana Prakarsa. From the research results of asphalt tile waste and fly ash substitution, there is a slump level of 6 cm - 8 cm, normal concrete has a slump value of 7 cm. The highest slump value is found on 20% asphalt tile, which is 8 cm from normal concrete. The biggest slump decrease occurred in 10% asphalt tile and 10% fly ash from normal concrete. At the age of 28 days, it can be seen that normal concrete has a water absorption value of 3.78%. Meanwhile, the water absorption with the highest value is found in 20% asphalt tile, which is 4.93%. The lowest water absorption value occurs in 10% asphalt tile, which is 3.40%. At the percentage of the mixture of 20% asphalt tile waste and 10% fly ash, the density decreased the most by 7.93% from normal concrete. The compressive strength value of normal concrete at the age of 28 days was 389.91 Kg/Cm2. The greatest decrease in compressive strength occurred in a mixture of 20% asphalt tile waste and 10% fly ash, which was 156.51 Kg/Cm2.]]>

<![CDATA[The current dense population of DKI Jakarta must be balanced with the provision of adequate transportation facilities and infrastructure. The current presence of pedestrians is usually concentrated in public facilities such as terminals, shopping centers, educational centers, and other public facilities. The existence of these pedestrians requires facilities for pedestrians, including road crossing facilities such as the People's Crossing Bridge (JPO), where the JPO is installed if it is required that there is no intersection between the flow of pedestrians and the flow of traffic. So that pedestrians want to use the JPO, it must be guaranteed safety and walking distance so that it does not get too far away. For this reason, this study was carried out to determine the effectiveness of the People's Crossing Bridge in the Youth Bracelet of the North Jakarta Administration. To determine the effectiveness of the pedestrian bridge at the Youth Center of North Jakarta City, the researchers observed the number of pedestrians for 2 days, namely during peak hours such as in the morning at 06.00 - 08.00 and in the afternoon at 16.00 - 18.00. From the results of the research for 2 days in the field, it was found that almost 58% of people did not use JPO facilities, and only 42% of people used JPO facilities. Thus, it can be concluded that JPO at the Youth Center of North Jakarta City Administration is classified as a fairly effective JPO.]]>
