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.

This paper presents an experimental study on repairing damaged beam-column reinforced concrete joints using carbon fiber reinforced polymer (CFRP). Eight specimens of exterior reinforced concrete beam-column joints were tested to identify an effective method for improving the performance of the joint in terms of lateral strength. These eight specimens were designed with four specimens using a grout repair and injection scheme, while another scheme with externally bonded CFRP sheets (EB) and surface mounted CFRP strips (NSM) was explored as different reinforcement options (NSM + EB combined). The test results show that with the addition of CFRP reinforcement, the performance of beam joints in damaged conditions can be significantly improved. In particular, the use of CFRP NSM strip schemes and CFRP sheets bonded externally to beams and joints can effectively remove the plastic joints from the joint area, thereby causing a ductile failure mode (beam bending failure), which demonstrates the effectiveness of this retrofit method. Where the NSM + EB scheme can improve performance against loads of 9.43%, 20.46%, 28.98%, 16.64%, respectively, compared to using only grout and injection.
So as to consent to the COP 21 Paris Agreement, in the Latin American region, the implementation of green power projects should constitute a main pillar. Consequently, the broadening of the power matrix must be inclined towards the consolidation of green energy and in this manner, the development of green power source ventures ought to be implemented. This article highlights the capability of the Clean Development Mechanism (CDM) to improve green energy projects and subsequently, to acquire profits by diminishing the effect of environmental changes thanks to green consumption. Additionally, this work studies key obstructions and open doors for promoting the constructing of clean power ventures prompting Latin America's green development. This study evidenced that, so as to progress in the development of green power ventures, new laws linked to clean developments ought to be established, proposing novel plans on sustainable viewpoints along with budgetary and administrative changes. Thus, new public policies, tax benefits, and administrative instruments ought to be set up. Financing components to create green power actions ought to be both sustainable and lucrative and, this is the reason the Clean Development Mechanism (CDM) should assume a fundamental part for expanding the proposal of sustainable projects as a way to survey the Kyoto Protocol's adequacy. Finally, advantages, for example, social framework ventures, through drinking water systems, emergency clinics, and schools can likewise be gotten from green projects
Cure fraction models are used when some units in the population of survival data are thought to survive the event of interest. Besides, modelling survival data with cure fraction provides a better fit. In this study, Mixture Cure Rate Modelling approach was briefly reviewed with some highlights on Non- Mixture and Defective Modelling approaches. Mixture Cure Rate Modelling assumes the population under study to be a mixture of susceptible and unsusceptible to the event of interest. Estimating cure fraction in the presence of either unobserved heterogeneity or zero-adjusted units were discussed. Mandatory assumption of the presence of cure fraction is a risk associated with this approach, which if wrongly done leads to misleading conclusion. The non-mixture modelling of cure fraction has a natural biological interpretation due to the process of its development. It is mostly associated with Bayesian statistical context. Estimating cure fraction using defective modelling approach makes no assumption of the presence of cure fraction; the cure fraction is estimated when the estimated value of the distribution shape parameter is negative. One of the shortcomings associated with this type of methodology is that, only few distributions can become defective. Zero-adjusted Frailty Mixture Cure Model is proposed
The European Union (EU) has recently established maximum limits for Ochratoxin A (OTA) in roasted and soluble coffee as well as for green coffee. Some countries have already established national limits for OTA in green coffee. Cup quality is a complex characteristic which depends on a series of factors such as the species or variety, environmental conditions, agronomical practices, processing systems, storage conditions, industrial processing, beverage preparation and taste of the consumer. This research was carried out to assess coffee storage & warehousing operations along the supply chain coffee from farmers/ cooperative warehouse up to Ethiopian Commodity Exchange (ECX) and Ethiopian Agricultural Commodities Warehouse Service Enterprise (EACWSE) branch warehouse as a case study in Sidama & Gedio Zones. The study employed descriptive analysis in assessing warehousing practices and problems of Coffee supply chain. Site observations and semi structured research were employed as research data collection. Interview questions were sent to various stakeholders, who gave their views on various warehousing practices and problems in accordance with how such problems impacted or influence their work. All the warehouses are substandard. The warehouses situations accelerate quality deteriorations due to moisture loss. This condition creates disputes and source of conflict because of coffee weight loss and compensation schemes between the top management and store managers. The field result demonstrates a lower level of material handling equipment uses. The warehouse operations are highly labour based. It was recommended that there should be effective strategy in adopting the FIFO principle, regulating trucks, introduction of weighbridge to speed up offloading process at the warehouses. The Coffee production and distribution traceability need to be supported by information communication technologies such as RFID
Non-singular matrices have a key role to play when determining the rank of a matrix. The rank of a matrix is useful when deducing the nature of solutions to a system of linear equations. In this paper I report on a qualitative case study which explored possible mathematical gaps that created barrier/s when engineering students (n=101) worked with the rank of matrices to determine the nature of the solutions of a system of linear equations. These engineering students were provided with two tasks and their written responses were used to detect possible barriers in their understanding of the rank concept. The study was carried out at a University of Technology in South Africa. The data, which was collected from written responses of students to two tasks, were analysed using APOS theory. Interviews followed these analyses to verify the APOS levels they were placed at. Findings emanating from the data analysis indicated that we: 1) can correctly place the APO level of conception of an individual if the individual provides a completely mathematically correct solution, 2) cannot be certain at which mental construction an individual is performing at when partially mathematically correct responses are provided and 3) individuals providing completely incorrect solutions require further exploration.
