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.

File carving is a technique to extract data from digital evidence and the signature-based approach searches data for patterns of file signature. As a response to demands of employing a high-performance string searching algorithm, the baseline algorithm, namely Boyer-Moore algorithm, is being widely used since proposed. However, there are more algorithms which are better than it, being continually proposed. Therefore, this paper aims to identify the best string searching algorithm that can be used for optimizing the signature-based file carving in term of time and memory usage. Therefore, a performance analysis against the baseline algorithm and its variations are performed. The findings indicate that the Shift-Or (SO) algorithm can be used as string searching algorithm in signature-based file carving due to its faster completion time and lower memory consumption. For future work, SO algorithm will be integrated with the file carving tools to test the capability of reducing the carving duration and memory usage while maintaining the similar carving accuracy.
Multi-objective optimization of EDM machining process of hardened 90CrSi steel will be presented in this study. The input parameters including Concentration of powder, Pulse on time, Pulse off time, Current, and Voltage are chosen to minimize the electrode wear rate and maximize material removal rate. Grey Relational Analysis (GRA) is combined with Taguchi method to find the optimal set of machining parameters which can satisfy the responses. It is found that Current has the strongest influence (24.89%), but Volgage has the smallest effects (1.63%) on the responses. The proposed model corfirmed by experiment and ANOVA exhibits the reability approch to predict electrode wear rate and material removal rate.
This paper presents a two-dimensional dynamic analysis for a human leg, a model was developed using a Lagrangian approach to describe the body-leg interaction. This model could be useful analyzing the human gait for people with disabilities in a lower limb, and also helps to design and improve therapy procedures. The aim of this research is restricted to a specific scenario: working out with a step machine-common machine usually found in fitness centers. The movement of raising and lowering the leg was modeled, which is the most relevant motion in this activity. In the process were identified the different anthropometric parameters for the human body in relation with the weight and height of a specific individual. A set of partial differential equations relate the force generated in the foot with three variables: The angle between the thigh and the vertical, its variation with respect to time (angular velocity) and the angular acceleration. The results showed that the dynamic condition increases the reaction forces about 16% in this activity. The developed sequence of analysis could be used for optimization processes based on anthropometric and movement conditions. These results are useful for detailed designs of prosthesis and also to find the best economical options for manufacturing aid devices that meet the dynamic requirements. The mathematical formulation process confirms the advantages of the Lagrangian over Newtonian approach for these types of systems.
through the holistic visionary plan 2030, Sulaimaneyah is aiming for a future knowledge and economic creative based development. It is taking one main pillar in the country vision strategy to build a well-established human force that will sustain the city and country growth. Sulaimaneyah City is assigned to be a cultural and creative hub that attracts creative workers from around the globe and establish its local creative human capital. In that regard, one can raise two essential questions: the first is this vision enough to start the creative culture economy and reduce its dependency on the oil-based economy to accelerate the creative city growth? The second; or do we need to adjust our city planning to flourish and support Sulaimaneyah creative cultural aspect? The study responds to these questions through running a qualitative and quantitative study of the creative cultural state of Sulaimaneyah creative city planning direction.
In highly populated areas like urban areas municipal solid waste (MSW) increases from time to time and it becomes serious issue recently. So it very important to make prediction of the wastes for designing and preparing enough land fill or any other mechanism used to store wastes, to hire enough man power and management system and preparing materials necessary etc. which are used to control the municipal solid waste. In this study Moving Average and linear regression method was used to forecast the municipal solid waste of mekelle city. Thus, the obtained equation used to forecast was, Y=0.757808*X+4.29 equation found used to forecast the proposed wastes. The Mean Average Percentage Error (MAPE), Root Mean Square Error (RMSE) was used as performance indicators for comparison between predicted and actual data Thus the result of the indicators showed acceptable error (very small error) and this indicated their good agreement between predicted and actual data.
