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 university need to improve their services for student, especially in this research focus on how to responses the student questions related the academic aspects. This research explained the analysis of chatbot model that suitable for university student. This research used Analytical Hierarchical Process (AHP) to determine the model of chatbot to response the student questions, the alternatives of this model are flow chatbot and artificial intelligence with natural language processing. The criteria that we used to analysis this model is easy maintenance, easy modification, error rate, performance, and cost. We used one expert judgement method to assess the chatbot based on those criteria. The results showed the suitable model for university student is flow chatbot at the initial state based on the current situation and complexity of university in Indonesia
Support vector machine (SVM) is one of the flagship methods in machine learning because SVM have good results in terms of classification and prediction. Classification Analysis is the process of finding the best model of the classifier to predict classes of an object or data whose class label is unknown. The study aims to select accurate classification methods in classification. The study used the Least Support Vector Machine (LS-SVM) method. LS-SVM is better compared to standard SVM in computation processes, rapid convergence, and high precision. On LS-SVM it has several parameters. Optimal parameter delivery on the LS-SVM method can affect increased classification accuracy. As for the various kinds of giving optimal parameter selection methods on LS-SMVS such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Gravitational Search Algorithm (GSA), Gird Search, and Particle Swarm Optimization and Gravitational Seach Algorithm (PAO-GSA). The study results show that the selection of more optimal parameters can result in significantly increased classification and prediction accuracy and more even computational process times. PSO-GSA is a method of selecting optimization parameters that can be used to improve classification accuracy
In this study, the paper introduces the surface roughness results of heat-treatment, and unheated-treatment SKD61 steel was processed by the EDM method with the participation of tungsten carbide powder. The least-square method was used to model the relationship between surface roughness of heat-treatment and unheated-treatment SKD61 steels, and these models were used to evaluate the role of each technological parameter, comparing the role of each technological parameter in the two models
The phenomenon of natural convection flow in a vertical cylindrical enclosure filled with unbound porous medium saturated by a Newtonian fluid has been investigated. The finite-difference method is performed to investigate the influence of uniform and non-uniform porosity along the z axis. The results of the numerical simulation obtained, presented in terms of streamlines, isotherms, local Nusselt number and average Nusselt number shows the dependence of the fluid flow pattern and the rate of heat transfer near to the heat wall on the variation of porosity is significant. The variation of the porosity along the z axis enhances the strength of fluid circulation. It is observed that the change from conduction dominant to convection dominant is obtained for low values of Rayleigh number in the case of variable porosity. Also, it is observed that an increase of Rayleigh number leads to an increase of the average Nusselt number while depending on the fluid flow pattern
The aim of this study is to identify the effect of entrepreneurial orientation and customer orientation on service quality in hotels operating in Gaza Strip, through examining the effect of risk taking, innovativeness, reactiveness, competitive aggressiveness and autonomy, in addition to examining the effect of definition, sensitivity, measurement and implementation on service quality in hotels operating in Gaza Strip. The researcher followed the descriptive, analytical approach. Data was collected using a questionnaire, which was distributed to the targeted population of the study – the employees in 13 hotels working in Gaza Strip. The questionnaire was distributed to a sample of (250) respondents from all hotels. Total of (189) questionnaires were collected and then analyzed using SPSS program. The results showed that there is a significant relationship between entrepreneurial orientation and service quality. It also revealed a significant relationship between customer orientation and service quality. And finally it showed that there is a significant relationship between the dependent variable service quality and the independent variables "Risk Taking, Innovativeness, Reactiveness, Competitive aggressiveness, Autonomy, Definition, Sensitivity, Measurement and Implementation "so that the higher degree of the independent variables leads to a higher level of service quality in hotels. The research recommended for the management of hotels to recruit its employees from the graduates of tourism and professional colleges so as to develop the level of quality services in the hotels operating in Gaza Strip. Furthermore, carry out workshops for administration and operational departments in order to improve their skills and c
