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.

The explosive growth in the use of mobile and wireless devices demands an adequate level of security for such devices. The security level need to be strengthen not only in device, but also in mobile application installed in the devices. This paper presents design in developing secure files transfer mobile application using digital signature technology; Elliptic Curve Digital Signature Algorithm. The developed mobile application consist of 8 main modules, including two modules that apply ECDSA algorithm; sign and send module. The developed mobile application not only secure the transferred file using digital signature, it also provide signature pad for user to enable user to use electronic signature for document
Information and communication technology (ICT) development gives great impact on organization’s growth. Organization growth can cause change of structure in the organization, whether it is predictably happened or in a sudden. Education sector also can have impact on structural change, that’s why succession planning is important. Education Institution needs to prepare the successor in a systematic and continuous program. The way to improve the succession planning process is by implementing Machine Learning. This paper uses Systematic Literature Review to find the trends of implementation machine learning in education sector. The result shows three types of trends such as concept, research and thesis or dissertation product. These three trends also come with some factor to improve succession planning and the implementation of machine learning
In order to make the charging process of the battery easier, it needs to possess a design tool with suitable characteristics. One of the main characteristics of the battery is the State of Charge (SoC) or simply the battery capacity, which is calculated with the help of the initial voltage value. In this process, a 100Wp photovoltaic panel with 12V DC voltage is applied. The method used is experimental and simulation/modeling, and its purpose is to optimize the efficiency of the process of battery charging. Furthermore, the Arduino microcontroller, which functions are a detector during battery charging, was used to determine the current and voltage sensor controller circuit. The voltage and SoC on the battery are automatically monitored via the LCD and on the SD card using the data logger shield module. ICM algorithm used for modeling-simulation in this study is one of the MPPT type used by photovoltaic systems that work at optimum conditions, thereby producing maximum power. The results showed that the battery charging simulation increased by 0.05% every 30 minutes. Furthermore, the simulation validation using Matlab/Simulink is carried out with data following the prototype design, at an efficiency of 88.37%
The research of synthesis of impregnated TiO2 Ouw natural clay with the study of calcination temperature has been done. The calcination process was carried out at temperature variations of 200, 300, and 400 oC. Characterization of the structure was performed by using X-ray diffraction (XRD), scanning electron microscope (SEM) and infrared (IR) spectrophotometer. The result of characterization with XRD showed that the impregnated TiO2 clay at 200 oC has the highest crystallinity. Calcination at 300 oC resulted in the loss of a montmorillonite reflection peak, while calcination at 400 °C resulted in the loss of two montmorillonite reflections and a drastic decrease in intensity. The crystalline phase of TiO2 formed was a combination of the crystalline phases of rutile and anatase, with the rutile crystalline phase being more dominant. The SEM characterization results showed a more even distribution of TiO2 in calcined clay. Calcination at 200 oC resulted in a more even distribution of TiO2 than calcination at 300 oC and 400 oC temperatures
Hussainiyat Formation (Upper Liassic) represents the uppermost of early Jurassic sediments. In the study area, the exposure section was formed in the intra-plate basin within the stable shelf, western Iraq. The main objectives of the study is to identify the lithology, microfacies, and sedimentary environment to interpret the origin of sequences that developed in the study area. The lower unit of Hussainiyat Formation consists from a repeated succession of sandstone, siltstone, and claystone, with relatively high intercalation between them, with common rusty color. Such sequence represents the low stand system tract phase, where the main sediment supplies are river-dependent. The upper unit is divided into four main lithofacies; Floodplain, Channels, Point bar, and Coastal plain facies. The sedimentation in this unite are dominantly of intercalation of varied dolomitized limestone facies, with thin laminations of sand and marl. The main distinguished facies were highly dolomitized mudstones, dolomitic peloidal packstone, and dolomitized grainstone. Three distinct depositional setting can be recognized: restricted marine, lagoon, and Shoal that are interpreted as a carbonate rimmed shelf setting. The exposed sections of the Hussainiyat Formation shows a major 3rd order (D1 and D2) and numbers of 4th order cycles (d1, d2, d3, and d4) these are asymmetrical and shows an upward increase in thickness. This may reflect the imbalance between accommodation and sediment influx for the clastic unit. Whereas the carbonate unit cyclicity shows a more or less balanced situation between the relative sea level rise, accommodation, and accumulation of sediment reflecting a relatively low subsidence
