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.

One of a major problem in electro discharge machining is the formation of the recast layer, which causes hard, brittle and micro cracks layer from the high temperature during machining. This article was focused on the method of reduces the thickness of layer damage of high speed steel work material by using a composite tool from copper-silver instead of copper tool. An experiment was carried out using a copper – silver composite tool and pure copper tool. The machining conditions included the use of the pulse current and pulse on time as input parameters. The morphology, microstructure of white layer was characterized by scanning electron microscopy. The results showed that the surface quality of high-speed steel after EDM with copper –silver composite electrode and copper electrode are dissimilar. In this case, EDM using composite electrode the recast layer thickness from pure copper electrode were reduced from the maximum value 14.56 μ m to 3.28 μ m moreover experiments showed improvement of micro hardness value from (297.1 to 193.6) Vickers of surface layer compared to the pure copper electrode
The tensile behaviour of two types of asphalt films confined between aggregates particles as adhered stub investigated. Axial finger aggregate samples fabricated using a modified prototype set up allowing construction of micro-scale thin films of asphalt's binder and digital visualization of failure phenomena stages. The effect of temperature (20°C and 10°C), binder type (neat and polymer modified), adhered type (two types of aggregate), and water conditioning were investigated sequentially. The results show that water sensitivity towards aggregate-binder combinations displayed reduced properties in the micro- scale when water conditioned. The tensile strength of the thin film of asphalt increases linearly with the binder film thickness to a maximum value and then it reduces with increasing test temperature and deformation rate. The average strength of the PMA is greater than pure asphalt binder due to the enhanced adhesion properties between asphalt binders with the aggregate particles. This increase requires higher external energy for failure. So the average stiffness reduction and average damage parameter is less than pure binder. The average elastic modulus and average hardness modulus for PMA is greater than unmodified asphalt binder
In Hai Phong – Quang Ninh seaports, the volume of hazardous and noxious substances has been increased rapidly in recent years along with the speed of industrialization in the North of Vietnam. Environmental protection, prevention and response to incidents with hazardous and noxious substances at these above seaport areas faced drawbacks such as poor infrastructure, lack of human resources and specialized guidance, inappropriate management models and limited financial resources. Therefore, this research proposed technical and management solutions in order to improve the effectiveness of environmental protection, prevention and response to environmental incidents during loading-unloading and storing hazardous and noxious substances at seaports. Based on the survey and assessment process at some typical seaports, using SWOT tool and referring to related documents and researches which authors evaluated the environmental protection, prevention and response with incidents during loading- unloading and storing hazardous and noxious substances at Haiphong and Quangninh seaports and proposed the management solutions such as: establishment a state management organization model for seaports; issuing technical regulations; strengthening human resources, finance and international cooperation; technical solutions including infrastructural improvements, incident prevention plan and applying ISO standards
The main objective of this research is to identify the possibility of contamination of groundwater in the area of Bahr Al-Najaf, middle of Iraq and thus can protect groundwater from impurities and assess the vulnerability of groundwater. This area is about (2500) km2. To achieve the groundwater vulnerability, the scope of pollution was analyzed by developing the seven map layers and generating the DRASTIC technique. Every parameter has a particular weight and rate value. After generate the desired layers, every pixel was reclassified and rated, thereafter, their respective weighting factor is multiplied it. The resulted index was divided into groups. Small values designated low vulnerability and large one is communicated to those areas that have high vulnerability. Due to the fact that the study area is characterized by an efficient agricultural and industrial effort as well as a wastewater treatment plant and many other sources of pollution, nitrate concentration was used to modify the typical DRASTIC technique of the studied area. The modified weight-and-rate applied to the DRASTIC technique index map with ranging of (81-221). The result map contains large variation with the typical DRASTIC map and to some extent like to the rate adjusted utilizing concentration of nitrate, with several variances in the rate of the very low and low vulnerability region
Computer and network threats are serious issues that are becoming prevalent in our daily life. IDS meanwhile, is a mechanism as countermeasure for network threats. Many studies were conducted to improve the capability of an IDS. However, there is a lack of analysis about the IDS architecture. The objective of this paper is to analyze the issues and challenges related to IDS architecture known as data collection, analysis and response module. The function of each IDS architecture module is discussed and use as the paper platform. An extensive analysis done to gather all issues related to IDS, and all the issues are being classified into the respective modules. The analysis is useful in understanding the IDS and its challenges. The contribution of this paper is critical to support the expanding research in IDS enhancement. In the future, this paper outcome can be use to highlight the current issues to be address in IDS research
