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.

Carbon foam is demanded in large quantities since it has certain attractive features like lightweight and high-temperature stability makes them versatile in many applications. Since the carbon foam from renewable resources gets a lot of attention, this study is a focus to fabricate a high strength carbon foam using natural resources such as sucrose and carbon whisker to produce good strength properties of carbon foam. The specimens were prepared via blowing method with varies loading of carbon whiskers of 0.1 wt%, 0.2 wt%, 0.3wt%, 0.4 wt%, 0.5 wt% and 0.6 wt% before mixing with sucrose and boric acid. Then, the materials are mixed uniformly with carbon whisker and boric acid for 2 hours. Next, foaming and setting of solid organic foam for 48 hours and dehydration for 16 hours. The carbonization in the inert atmosphere takes place for 2 hours constant temperature and the heating rate at 2°C/min until 900°C. The morphology, porosity, density and compression properties were analysed in this study. SEM analysis presented the distribution of carbon fibre on the wall structures and some debonding and holes were observed. Images of carbon fibre still bonded between walls surfaces and embedded on the wall structures were also observed. The bulk density result shows that the highest carbon whisker contains has a higher value reading which is 0.238 g/cm3 with 84.87% of porosity. The highest whisker carbon contains shows a good result in compressive strength which is 0.13 N/mm2 and it can be concluded as the best parameter among their carbon loading
This paper presents a time optimization study to find optimal exchanged wheel diameter when internal grinding stainless steel. To do that, the minimum grinding time was elected for the target of the optimization problem. In addition, five process factors were carefully chosen for the exploration. They are the original wheel diameter, the wheel width, the wheel wear per dress, the wheel life, and the total depth of dressing cut. Moreover, to weigh the effects of the input parameters on the optimal exchanged wheel diameter, a simulation experiment was designed and accompanied. In addition, a regression model was presented to estimate the optimal exchanged wheel diameter
The digital world is rapidly converging and converting a lot of our valuable data on to its digital equivalent. Its dissemination as eased via the advent of the Internet has also led to and encountered many attacks due to predictable responses from users. This has evolved the field of social engineering and exploits of user trust-levels. Thus, the use of deception mechanisms now plays a prominent role in enhancing the field of cyber and data security. There exists many techniques to dissuade and/or redirect adversaries via deception mode commonly called honeypots. They seek to detect intrusive activities by adversaries using services that attract the attacker to it. Honeypots have been successfully employed to minimize security breaches. We explore deception-based mechanism (honeypot) as an effective means to minimize data exploitation by adversaries – implemented via web servers and equipped with tracking and identification capabilities as the system learns and defends the user system against intrusive actions.
Evolution in the concealment of data was reflected in the medical field specifically on medical images and becoming more challenging and an enthusiastic area of research since the last decades over the dispersed IoTs. Hide information technology in the image is called steganography. The objective of this study is the preservation of privacy and confidentiality of data in uncertain surroundings during multimedia exchange joining two IoT hops. For attacker hindrance and, provision of data confidentiality, a resilient multilevel security perspective depending on information hiding and cryptography is suggested. The existing schemes have limitations related to the equilibrium trade-off amid two variables (medical image quality and security). In addition, the direct embedment of the secret data into the images and further subtraction of encrypted data from it often enables the intruders to easily detect and extract the hidden information. Based on these factors, we proposed multilevel security based on three random iterations with chosen a procedure that was implemented using Henon function to stop against cybercrimes challenges. Satisfying results, gained when benchmarking our results with the existing methods in literature through the same criteria
Prevalent years have witnessed the rise in a plethora of data security issues that run across the board from copyright to content security issues due to the multitudinous transmission and sharing of multimedia activities across communications conduit that utilizes the network, which is not secure. Consequently, the requirement for the latest security techniques in data hiding such as steganography is now imperative and indispensable. Thus, steganography entails the skill and science of concealment of existing confidential information by concurrently making the communications imperceptible through the utilisation of diverse media carriers such as Image, Text, Audio, Video, Protocol and DNA. Amongst the varying kinds of media utilised, the findings of this study show the high demand and proliferation of digitalized images, thus the emphasis of our study is pertaining to the implementation of digital image steganography (IS). The major problem in the construction of a steganography system is the maintenance of a compromise between robustness, security, imperceptibility and a greater rate of bit embedding. This study offers a comprehensive summary of current IS forms, alongside the latest endowments of individual classification in a wide range of aspects and modes of operations. Additionally, this study offers a comprehensive summary of IS inclusive of customary operation, necessities, varying aspects, diverse forms and their performance assessments, protocols, and types of attacks. Diverse performance analysis measures for the evaluation of steganography systems are also deliberated here
