Deep neural network for system of ordinary differential equations: Vectorized algorithm and simulation

Abstract: This paper is aimed at applying deep artificial neural networks for solving system of ordinary differential equations. We developed a vectorized algorithm and implemented using python code. We conducted different experiments for selecting better neural architecture. For the learning of the neural network, we utilized the adaptive moment minimization method. Finally, we compare the method with one of the traditional numerical methods-Runge–Kutta order four. We have shown that, the artificial neural network could provide better accuracy for smaller numbers of grid points.

Importance of a View Window in Rating Green Office Buildings

Abstract: The essence of a view window (VW) in an office building is not only to bring an optimal balance between daylight and electric light, but also for psychological and health purpose. VW does not only allow the admittance of light and views, but indirectly affects the productivity and psychological wellbeing of office occupants; it has a link to the sustainability in both conventional and green buildings. This paper defines the function of a view window as it relates to green office building. Through literature review and an experiment conducted in room 432-01 located at B11 Faculty of Built Environment, Universiti Teknologi Malaysia. The function of VW in a green office building is highlighted; and the findings show that a VW would enhance sustainability in an office setting and has a dimension greater than 750mm above a finish floor level and less or equal to 2300mm above a finish floor level and with a wall to window ratio (WWR) of 25% to 40%.

Adapting participatory design to design information system with rural Ethiopian community

Abstract: Most of the Information and Communication Technology for Development initiatives introduced to communities in developing countries fails to deliver its promises due to the lack of intended beneficiary involvement. Participatory Design assumes to be effective as long as its nature of participations and methods are contextualized to a given settings. To this end, we discuss the implication of considering local (rural community) culture of participation practices, and propose a procedure to be followed in the early phases of information system development process. Finally we argue that, such adaption could advance the Participatory Action Research methodology.

Effect of Capital Structure on the Performance of Listed Consumer Goods Companies in Nigeria

Abstract: Managers of corporate entities are mostly in confrontation with the problem of; what combination of capital structure (equity and debt) will maximize returns and value of their firms? The study, therefore, aims at assessing the effect of capital structure on the financial performance of listed Consumer goods companies in Nigerian. All consumer goods companies quoted on the Nigerian Stock Exchange are considered the population for this study while seven (7) out of these firms whose accounting year-ends 31 December are considered as the sample. Secondary data was utilized from the annual financial reports of the sampled firms from the year 2008-2013, which was obtained from African Financial website and official website of Nigerian Stock Exchange. The study used ex-post facto research design to examine the relationship between independent and dependent variables while controlling for other variables. Descriptive statistics, correlation, and hierarchical multiple regression analyzes were carried out to test the hypotheses developed in the study. The study found that there is a positive and significant relationship between firm’s capital structure and corporate financial performance. The study specifically found that short-term debt (STD) has no significance positive effect on return on equity (ROE) while Long-term debt (LTD) has positive relation and significant effect on ROE. The study recommends that firms should consider the mixture of equity and debt since they are major determinants of corporate performance. Authorities concerned should create an enabling business environment for companies (especially those with low capital) so as to have access to long-term debts to finance their operations and improve performance in the shortrun, instead of using high short-term debts to cushions for financing and profitability problems.
