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.

So far, various methods have been proposed to deal with cyber-attacks, but many of them are not capable of running in the real environment or do not have enough accuracy to detect different types of attacks. In this paper, using the features of k-means clustering algorithm, ineffective data in detection process are removed from the dataset. Then, the accuracy of attack detection increases by using the Gray Wolf Optimization (GWO) algorithm and replacing stronger wolves based on their degree of suitability. In each iteration of the algorithm, the fitness is computed and if it improves the algorithm is repeated again, otherwise the algorithm terminates. The main purpose of the proposed method is to increase the accuracy of detection as well as reduce the likelihood of getting stuck in local optimal points. The simulation results on 4 different types of attacks in the NSL-KDD and synthetic dataset show that about 3.2% better detection accuracy is obtained rather than other researches by adjusting the parameters of the gray wolf algorithm, as a conclusion, the proposed method has the necessary efficiency for detecting attacks on computer networks
with the incremental growth of the communication system, information security becomes an important issue. The need for securing information in fast, reliable, and relatively low-cost methods lead the researchers to work intensively in this field to find the optimum protective method that satisfies these requirements. A stream cipher is the most widely used technique in securing transmission data in the communication system since the overall security of the system depends only on the keystream used. This paper presents an intelligent approach to generate a keystream based on a combinatorial generator and clock-control generator. The design includes new techniques such as the saturated best resilient (SBR) function as a combined function and two nonlinear feedback shifts register (NLFSRs), using recency based memory techniques from the Tabu search to implement the clock-control method. The developed generator focuses on the keystream design for stream cipher by combining the strongest of the combinatorial generator with the complexity in the analysis of the clock control generator to avoid high immunity attacks. The output keystream from the generator passes the entire NIST test and two more correlation test with very good results
The Education for Sustainable Development (ESD) program, which is education for the development of elements that occur continuously or sustainably, was born amid an environmental crisis in all regions including Bandung City. The environmental crisis includes the water crisis. The sustainability of water for life is increasingly critical, people find it difficult to get water during the dry season and get floods when it rains. Therefore, it requires public awareness to care and understand water management techniques for life. In this study, researchers used an effective way of education through digital technology-based educational media, such as animation, video, web, Apps/APK in one training aimed at elementary school teachers. This research method is grounded research by taking to the field educating thirty elementary school teachers in Bandung City about Sustainability Water. The training is conducted for half a year. After the teachers underwent the program, the researchers distributed questionnaires about the success of the program. Analyze the data by analytic descriptive. All respondents thought this program helped them gain insight into Sustainability Water
Friction stir spot welding a relatively new solid-state joining technique usually used by automotive manufacturers as alternative to rivets and conventional spot welding resistance has led to the development of a fairly new technique a double-sided friction stir spot welding technique, this method was implemented for aluminum alloy AA6061-T6 by 2 mm thick, with rotating anvil, pin less tool for similar weld joints. Using double-sided FSSW technique increased welded joints strength. The design of rotating anvil and pin less tool for welded aluminum AA6061-T6 alloy has achieved a high tensile strength and avoid a defects such as keyhole. The cross-section welded joints, numerical analysis method explains that the material flow between pin less tool and rotating anvil is complex, using a rotating anvil and pin less tool with FSSW operation, suitable method for welding thicker sheets
The particles surface charge is classified among the essential criteria in the coagulation and flocculation treatment. Colloidal particles in suspensions are generally dispersed, electrically charged and do not settle by the gravity due to its stability and repulsion. Good settling can be achieved by disrupting the surface charge in the suspension of unstable particles. The zeta potential (ZP) is an indicator or criterion that represents the electrostatic interactions in a particle dispersion and is a measure of particle surface charges. This paper evaluated the mechanism and the effect of pH, ZP and particle size of colloids on the reduction of colour and suspended solids (SS) in leachate by the positive charge coagulant, Tin tetrachloride (SnCl4). A range of experiments on coagulation and flocculation was undertaken using the standard jar test with ZP measurement. It was found that the addition of positively charged SnCl4 as coagulant increased the leachate surface charge. The maximum ZP before the addition of SnCl4 was -22.4 mV at pH 11, and the surface charge of leachate was closed to the point of zero charges at pH 8 with -0.4 mV after the coagulant was added. Highest colour and SS performance were observed at optimum pH 8 with reductions of 98.9% and 100%, respectively. The reduction of repulsive forces at this pH promoted the collision of particles and thus made the aggregation possible
