Tillage Appearance Device Test When Used Mold Board Plow Under Difference of a Variables Condition
...Show More Authors

Tillage appearance device is mechanical, electric-electronic design, getting Patent from the Central Organization for Standardization and Quality Control – Industrial Property Department - Ministry of Planning – The Republic of IRAQ under number Patent 3876 in 20 / 4 / 2014, calculates the number of clods per area by Tillage appearance device, This is done through the generation electrical impulses are sent to the controlled accurate calculates number clods required space and shows the result on the screen in order to see the tillage view per area. Three factor used in these experiment, first factor represents forward speed of tractor three levels (3.5, 4.5, and 5.5 km/h), second factor represent soil moisture content at two levels (14 – 17 and 17- 20 %) and third factor was depth of tillage at three levels (10 ,15 and 20 cm) in texture silt clay loam in Wasit cityIraq. Split – split plot design under randomized complete block design with three replications and Least Significant Design 5 % was used to compare the between means of treatments. The result showed that significant differences to forward speed to the tractor on tillage appearance of more than 10 cm. Speed 5.5 km/h recorded lower number of clods 10 cm 6.5230 clods/m2. Also result showed that the increase soil moisture content from 14-17 to 17-20 % led to increase the tillage appearance more than 10 cm from 7.5178 to 9.6200 clods/m2 for tillage appearance device respectively ,while the conventional method recorded 9.1639 to 9.9400 clods/m2. Observed also depth of tillage 10 cm for the least number of clods soil more 10 cm were 6.753,6.9633 clods/m2 when used the tillage view device and conventional method respectively. There was a significant correlation between the reading of the tillage appearance device and conventional methods which means that the reading device was Accuracy.

Development of Regression Models for Predicting Pavement Condition Index from the International Roughness Index
...Show More Authors

Flexible pavements are considered an essential element of transportation infrastructure. So, evaluations of flexible pavement performance are necessary for the proper management of transportation infrastructure. Pavement condition index (PCI) and international roughness index (IRI) are common indices applied to evaluate pavement surface conditions. However, the pavement condition surveys to calculate PCI are costly and time-consuming as compared to IRI. This article focuses on developing regression models that predict PCI from IRI. Eighty-three flexible pavement sections, with section length equal to 250 m, were selected in Al-Diwaniyah, Iraq, to develop PCI-IRI relationships. In terms of the quantity and severity of eac

Interannual variations of normalized difference vegetation index and potential evapotranspiration and their relationship in the Baghdad area
...Show More Authors
Abstract<p>A monthly correlation between urban vegetation growth and potential evapotranspiration (PET) is needed for better knowledge of controlling water resources and organized irrigation processes. This study aims to explore their relationship within an urban area like Baghdad, using a linear regression model to derive a best-fit line drawn in a scatterplot on a monthly time scale. Based on two different monthly data sources: weather variables (e.g., air temperature, solar radiation, and relative humidity) and Sentinel-2 satellite imagery of 2 years, 2018 and 2021, this study presented the interannual variations of PET and normalized difference vegetation index (NDVI). The choice of these ye</p> ... Show More

Apparent Viscosity Direct from Marsh Funnel Test
...Show More Authors

Accurate and simple techniques for measurement of fluid rheological properties are important for field operations in the oil industry. Marsh Funnels are popular quality-control tools used in the field for drilling fluids and they offer a simple, practical alternative to viscosity measurement. In the normal measurements, a single point (drainage time) is used to determine an average viscosity; little additional information is extracted regarding the non-Newtonian behavior of the fluid.
Here, a new model is developed and used to determine the rheological properties of drilling muds and other non-Newtonian fluids using data of fluid density and drainage time collected from a Marsh Funnel as a function of viscosity. The funnel results for

Test design to measure the cognitive processing speed of table tennis players
...Show More Authors

Table tennis is considered one of the fast base sports that the player needs to have the speed of performance and awareness, especially in straight forward and back strikes, which is an important offensive skills, and the player success depends on his perception speed to the point of the fall of the ball in the arena of his competitor. But there is no way to measure cognitive processing speed. Therefore, the researchers sought to design a test that measures this ability to ensure its scientific evaluation, and then establish standard scores for this test for the players of the specialized school of table tennis, to help evaluate them objectively and move away from subjective estimates when evaluating and developing measuring instruments in

Fuzzy-assignment Model by Using Linguistic Variables
...Show More Authors

      This work addressed the assignment problem (AP) based on fuzzy costs, where the objective, in this study, is to minimize the cost. A triangular, or trapezoidal, fuzzy numbers were assigned for each fuzzy cost. In addition, the assignment models were applied on linguistic variables which were initially converted to quantitative fuzzy data by using the Yager’sorankingi method. The paper results have showed that the quantitative date have a considerable effect when considered in fuzzy-mathematic models.
