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.

In this study, copper oxide nanostructures were prepared by an easy, simple, short time and economical electrochemical method using polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA) as stabilizing agents. Copper is used as precursors as melt anode electrodes during electrolysis to prepare CuO particles. The characterization of the prepared CuO NPs was studied by field emission scanning (FE-SEM), transmission electron microscopy (TEM) and atomic force microscopy (AFM). The FE-SEM images of CuO / PVA and CuO / PVP were both rectangle and regular cube shapes respectively. TEM images were prepared from CuO / PVA and CuO / PVP. They had an average size of 30-50 nm. The XRD results revealed the hexagonal structure of CuO nanoparticles. The optical properties of the prepared CuO / PVA and CuO / PVP nanoparticles were studied through UV / VIS spectroscopy. The optical band gap was found to be 3.60 eV and 3.75 eV for CuO / PVP and CuO / PVA. Dye solar cells were designed using CuO / PVA and CuO / PVP as positive electrodes (front electrode) and graphite as cathode (back electrode) deposition on the surface of ITO glass in the presence of two types of natural dyes, these are cabbage and spinach dyes, and iodine / iodine electrolyte solution. The PV cells prepared using spinach dye were more efficient. It is noticed from the data that the dye has a very important role in increasing the efficiency of the solar cell, as the cells made from spinach gave a much higher efficiency than the cells prepared from the red cabbage dye in all cases.
Software design is described as the process of defining the architecture, components, interfaces, and other characteristics of a system or component plus the result of the process that births the design with an overall aim of creating the architecture on which the software will run. However, software designers are faced with numerous concerns during system design. This work discussed basic concerns namely security, modularity, performance and re-usability. Each of the issues were briefly and separately analysed to understand the intricacies. It was revealed that the use of models, understanding and predicting computers’ future, excellent system structuring control modeling, and modular decomposition are some of the solutions to the issues raised. Conclusively, since humans are still susceptible to errors and to adequately alleviate the impact of such during designs, designers and experts generally must understand high-level design concepts. The best architects don’t have to know how to implement all levels of design they only need an understanding of all the levels.
