Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This study discusses the results of smelting of beverage cans poured into a tube mold, 5 cm in diameter and 30 cm high containing 6 ml, 12 ml of used lubricant, and without used lubricant as a comparison. Samples were treated with quench heat at 550 oC for 2 hours and aging at 175 oC for 1, 3, and 5 hours, respectively, to determine their effect on material hardness. From the analysis, it has been shown that the maximum aging time to increase the hardness of the material with and without the addition of used lubricant is 3 hours, then decreased after 5 hours. As well as the addition of used lubricants, the results show the hardness of aluminum material has decreased
In the past few years, the use of digital photography has increased, a development that opens the door to new and innovative ways of creating images. There are now many applications for a day that is used to modify the image so that the image looks like the original. Images are used for any crime as authenticated proof and if this image does not remain real then it will create a problem. Detection of these types of forgeries is now becoming a serious issue. A forgery of copy-move images is done either to hide some image entity, or to add more details that results in forgery. In both cases, reliability for the picture is lost. The digital image processing technique discussed in this paper is MATLAB’s role in detection or in any manipulation of digital images. This study focuses on document analysis such as Passport, Driving License, Certificate, and Employment Card which is widely created for use as proof of identity for various wrongful benefits. The goal of this study entitled is to assist the forensic record expert in the use of digital image processing techniques to implement the manufactured record detection, Segmentation and analysis procedure
Cranes are designed for lifting, moving heavy loads in factories, workshops or in ports, they require a high level of safety and reliability. Therefore, ensuring durability is not enough for the calculations and design of the crane. This paper solves the optimal design problem of double girder overhead crane based on reliability. A crane model shall be built in double girder structure, closed rectangular box shape cross section, the rail trolley shall be considered to be a portable load in which a pendulum type load is suspended. We have built the oscillating differential equations, the force equation, the moment equation, and the deflated equation, from there, determined the maximum forces and moments placing on the beam. We used strength conditions to determine the cross-sectional area of the girders. The factors of safety fs = 1.5, fs = 2.0, and fs = 2.5 produces the result of As = 8156.52 mm2, As = 9410.94 mm2, and As = 10516.14 mm2 respectively. Then we used mathematical statistics to determine the cross-sectional area according to the reliability, the result is As = 8362.08 mm2 corresponding to the factor of safety fs = 1.58. The achieved results show that when calculated under durable conditions, the factor of safety is often selected based on the experience of the designer. Therefore, it is not possible to calculate the risks occurring during the long operation time of the crane, causing economic and human costs. In this study, we have overcome the disadvantages to ensure the reliability of the crane structure with the optimal size
Using the CR-39 detector the fission-track registration technique was employed for determination of the uranium (U) concentration for 10 tooth samples found at Karbala city in Iraq. Each sample was 1.5 mm thick and 0.5 g in weight. Measurement of the uranium concentration in the samples was made by employing the CR-39 track detector to follow fission tracks caused by bombarding uranium with thermal neutrons from the 241Am-Be source that has a flux of 5 ×103 n cm-2 s-1. Calculations of the concentration levels were made through comparison with standard samples. The outcomes demonstrated that the minimum uranium value is 0.038 ppm and the maximum uranium value is 0.078 ppm
In this work, ANSYS WORKBENCH finite element analysis is used to construct and solve the problems related with the surface crack in round bars under combined bending and torsion moments. The solutions of stress intensity factors under combined loading are then compared with the results combined explicitly from the individual loading. Based on the observations, the pattern of all stress intensity factor is symmetrical and there are some discrepancies between both results as maximum as 4% where the combined stress intensity factors obtained directly from finite element analysis is always higher than the stress intensity factors obtained explicitly. However, for the case of area close to the outer surface, the stress intensity factors from both methods are well agreed to each other
