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.

High-dimensional data is interpreted with a considerable number of features, and new problems are presented in groups. The so-called "high dimension" is initially created to explain the common increase in time complexity of many computational problems, and therefore the performance of general aggregation algorithms is unsuccessful. Accordingly, many works focused on introducing new technologies and aggregation algorithms to process data with higher dimensions. Standard algorithms for all aggregate algorithms are the fact that they need a different essential evaluation of the similarity between data objects. However, current aggregation algorithms still have some open research problems. In this review work, they provide a summary of the results of the high-dimensional data space and its effects on different aggregation algorithms. It also provides a detailed overview of several grouping algorithms with several types: subspace methods, model-based grouping, density-based grouping methods, partition-based grouping methods, etc., including a more detailed description of the recent work of its advantages and disadvantages in Solve the problem of higher-dimensional data. The scope of future work is also discussed at the end of the work to expand existing compilation methods and algorithms
In this work, we study the influence of the millet pod on the compressive strength of clay bricks from the Maradi region. These compressed bricks are stabilized by the percentage of cement (4 %). A geotechnical characterization was carried out and allowed the classification of the clay which was used to make these bricks. It appears that the material under study is plastic clay and can be classified according to the "AASHTO" (American Association of State Highway and Transportation Officials) classification, A-7-6 (18). The measurements have shown that the values of the compressive strength vary between 2.41 MPa and 5.18 MPa. The optimal value is obtained with 4 % of millet pod
Traffic performance of signalized intersection is always difficult to be described by road users. They unable to plan their journey accurately if they under- or over-estimate traffic performance especially in crossing a signalized intersection. Traffic engineers who desire to overcome the problem of congestion at signalized intersection required to carry out a study before they are able to suggest any recommendations or improvements. Level of Service (LOS) is generally used for defining or describing the actual traffic performance by providing standard explanation to the road user. It is easier and simpler to be understood by the road user by categorizing the traffic performance into several levels. 1985 HCM delay model was chosen in this study to investigate and estimate the delays at signalized intersection for determining LOS. The longer the delay, the worse the LOS. Parameters such as saturation headways, saturation flow rates, loss times, actual green period and cycle time was obtained by analyzing the field data collected from the study area. All parameters were interrelated to carry out the estimation of LOS to provide a clearly defined explanation to the actual traffic performance at the study area. However, the delay model is just estimation for LOS and it may unable to fully reflect the actual condition on site. The results and conclusions obtained through this case study will be the references to evaluate the traffic performance at the signalized intersection
The present study deals with calculating optimal exchanged grinding wheel diameter to get the minimum manufacturing time when external grinding tool steel. To do that, four input factors covering the initial grinding wheel diameter D0, the radial grinding wheel wear per dress Wpd, the wheel life Tw, and the total dressing depth aed. Also, for weighing the effect of the process parameters on the optimal exchanged wheel diameter dop, a simulation experiment was designed and performed. In addition, a proposed equation to find the optimal exchanged wheel diameter was given
The Lahendong Unit 3 geothermal power plant (PLTP) is a PLTP type of dry steam power plant and the thermodynamic cycle that occurs in the system is the Rankine Cycle. The objectives of this study are: a) Analyzing the temperature of the influence of the main air cooler on the performance of the turbine unit in Lahendong Units 3, b) Analyzing environmental factors that affect changes in the temperature of the cooling air which serves to improve its ability to repair the turbine. The method used is a survey method. The data used in this study is PLTP operation data for one month which is used to find turbine solutions to compare with the temperature of the main cooling air and ambient temperature. Resulting from the temperature of the main cooling air (cooling tower outlet) increases, the performance of the turbine shows a low number, on the contrary the temperature of the main cooling air increases, the performance of the turbine will rise. Factors that influence the main air temperature, the temperature and the temperature of the cooling tower inlet or the temperature of the air coming out of the condenser
