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 objective of this study is to simulate the impact of point source and non-point sources of pollution to the river tributary in University Sains Malaysia (USM) by using QUAL2K. Three parameters are used in simulation which are Biochemical Oxygen Demand (BOD), Ammoniacal Nitrogen (NH3-H), and Total Suspended Solid (TSS). Chemical Oxygen Demand (COD) and Dissolved Oxygen (DO) are measured in order to calculate the Water Quality Index of the river. Trial and error method is used to calibrate the model parameters until the simulated results agreed with the observed data. Then, the low flow scenario is simulated to observe the impact of pollution on the river during low flow. Results shows Water Quality Index (WQI) of river tributary in USM was classified as Class III, which agree with Environmental Quality Report 2018. The main pollutants of the river were Ammonium Nitrogen (NH3-H) which the concentration of NH3-H of all sampling stations exceed 2.7 mg/L. Low flow simulation shows BOD and NH3-H of the sampling station exceed 2.7mg/L (Class IV) at the downstream of the river while TSS concentration maintain Class I at the downstream of the river
The present plot is a reviewed construction of determination of thermoelastic characteristics such as thermal stress, displacement function and temperature distribution. A plenty of publications since sixth decade of nineteenth century were referred. The plates such as rectangular, circular, hollow cylinder and annular disk have been taken into account for the study and analysis by using heat conduction equation. The stress function, distribution of temperature etc. was evaluated by using mathematical tool of integral transform technique. Furthermore, different materials as a special case were considered and can be referred as a research platform in future
Improving occupational safety and health (OSH) performance in the construction industry is crucial because it represents the excellence of the executed projects, and more importantly the protection of life for people who work in the field. One initiative for improving the performance of OSH in construction is through the application of risk management concepts. Effective risk management depends on the consensus and collaboration of all stakeholders, but such integration is hard to attain. This study seeks to investigate the level of shared understandings of perceived risk among construction stakeholders. Utilizing two case study scenario survey that represents the risk exposure or consequence due to crush of panel and vibration activity, data were collected from a sample of 12 representing construction professionals in Malaysia. Data analysis describes the variety of risk perceptions among stakeholders in construction. The immediate-type of risk was rated higher than those from expected scores, whereas delayed-effect risks such as ‘vibration’ in this study, were rated lower than those from expected scores. Findings from this study suggest that there is a need to have a strategic measure to engage stakeholders in the risk management process and should take account of people’s perceptions of risk
Data mining techniques had used to detect DDoS attacks by analyzing network traffic patterns. The random forest (RF) algorithm is used as a detection model after dividing the dataset into (training data) and (test data). Encoding was utilized to initialization the data set used, which is an important step in the preprocessing process to obtain the best results the log2 algorithm is used to standardize data. In addition, the principal component analysis (PCA) technique is applied several times to reduce data dimensions. Emphasis was placed on strengthening the preprocessing step to obtain high accuracy and efficiency in the classification and detection of attacks. In this paper, the proposed model was applied to datasets (CICDDOS2019) it is extracted from CICIDS2018, the dataset has two versions, the first version is CSV files, which contain 13 different DDoS attacks, and another version is raw PCAP files. The results showed an increase in the level of accuracy when using the PCA technique to 99.9%
Conspicuity issues on motorcycle at night time have always been a big concern as it is frequently observed motorcycle ridden without its light functioning and motorcyclist donning low conspicuous attire. This somehow has contributed to high percentage of motorcycle crashes at night time especially at junction road and rural area. This study aims to propose ways to improve the side conspicuity of motorcycles traveling on Malaysian roads at night through brighter appearance of motorcyclist and new intervention using retroreflective tapes on the side body of motorcycle. 38 drivers with average age of 34.8 years (SD=7.95) participated in a video experiment to detect a motorcycle presence on the road. Multiple motorcycle configurations with conspicuity measures of helmet color, attire color, presence of motorcycle light and retroreflective tapes were included in the experiment. The results indicate that a motorcycle without any conspicuity aid can be detected at average 33 meters from its side. The use of conspicuity aids of bright helmet, attire, presence of motorcycle light and retroreflective tapes have resulted in better motorcycle detection distance with the use of retroreflective tapes have helped motorcycle to detect furthest and quickest. Brighter motorcyclists’ and motorcycle’s appearances have improved motorcycle detectability at night time. Furthermore, the addition of retroreflective tapes on the side body of motorcycle have significantly improved motorcycle conspicuity and this suggested that the use of retroreflective tapes can help in reducing motorcycle conspicuity related crashes at junction road area at night time
