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.

Electroencephalogram (EEG) signal interpretation has been developed for various purposes such as brain health examination, brain detection, brain trauma, emotional condition, and even predict the response that will occur. The complex form of EEG signals will complicate one's interpretation visually so that it requires neurologists to deduce it. One of the brain disorders that are of concern and can be detected through EEG is epilepsy. EEG signal patterns can be identified through excessive brain cell activity before or after a person experiences seizures without cause. In this study, we proposed an EEG epilepsy signal recognition using Wavelet Time Entropy (WTE) as the main modality to obtain signal features. 300 EEG signal consisting of 3 classes (normal, interictal, seizure) has been tested with the highest accuracy result of 86.3% generated by Db 2 with decomposition level 2 or 3 using cubic Support Vector Machine (SVM)
The liquid fission products (including 90Sr) waste could be treated by the adsorption method. The metal-organic framework (MOF) has been known as an adsorbent that could be used to treat waste, but its utilization for treating strontium waste has rarely been researched. This paper aims to explain the ability of some MOF materials (MOF-5 and MOF-199) in adsorbing strontium from liquid waste. The MOF synthesis was conducted by the solvothermal method. The SEM, XRD, FTIR, and BET used to test the characteristics of synthesized crystals. The concentration of liquid strontium waste was varied at 25 ppm, 50 ppm, and 100 ppm. Another variable is the adsorption temperature that was varied at room temperature (27oC) and 35oC. Both MOF-199 and MOF-5 were added in each variation. The supernatants formed were tested by Atomic Absorption Spectrophotometer (AAS) to measure absorbed concentration. The sampling points were at the 10th, 30th, 40th, 50th, 60th, 90th, and 120th minutes. These were calculated using the Langmuir adsorption model. The synthesis of MOF-5 and MOF-199 has been successfully conducted by solvothermal method that is confirmed with the XRD, FTIR, BET, and SEM tests. The MOF-5 synthesized in this research has a much better adsorption capacity than MOF-199 one at room temperature. The MOF synthesized in this research (370.37 - 833.333 mg/g) has much better maximum adsorption capacity for strontium than reported by other research
Impact and socioeconomic effects of climate change are diverse, highly ambiguous, and varies depending on space and time. Innovative technology is an important response to operational and realistic adaptation and mitigation of such threats posed by climate change. Hence, articulating means, ends, and mechanisms to advocate and develop innovation technology towards addressing these diversities and/or ambiguities as to variations in climate, is considered a worthy project. In this study, an attempt is made to present a concrete but succinct review of some current developments in technology as applied towards containing climate change. It is submitted that while innovation technology is apt, climate change in its entirety should be addressed in a holistic manner that adopts a sociotechnical standpoint with the involvement of public and private sector partnerships. The authors conclude that innovation technology when anchored by political will would drive vital adaptation projects that could ameliorate the damning impact of climate change
In this article, we investigate the sufficient conditions of the regular solvability for parabolic operator-differential equations of the higher-order (nth-order) with initial-boundary conditions on the halfaxis R+ in the Hilbert space. These conditions depend on the coefficients of the operator-differential equation. The exact values of the norms of the intermediate derivatives operators of the important part of the investigated equation are found. For the partial differential equations, a mixed problem is introduced as an applied result of this paper
This paper attempts to focus on inverse steady state thermoelastic problem of thin rectangular plate by means of internal moving heat source. For a given problem known second kind boundary condition and initial condition is applied. This is analyzed and solved by applying Fourier cosine transform and Marchi-Fasulo transform to obtain temperature distribution and its results are is an infinite series. The various different transformation and boundary conditions have been used for solving this kind of determination. Temperature distribution, thermal deflection and different kind of stresses have been focused and elaborated by considering the condition of temperature. This work puts lights on evaluation of unknown function. The integral transform technique yields the solution of inverse problem.
