Foreign Direct Investment (FDI) is a strategy used by the majority of developing nations, including Nigeria, to increase their foreign exchange reserves through investments, business ventures, and international aid. The main goal this study model investment returns economic growth in Nigeria. To my knowledge, no prior research on relationship between FDI has simulation with differential equatio...

Usually people make a visual representation of what they read. This is a fact inherent to their nature. Many efforts have been done in the last years to try to find a direct method to translate a text wrote on a natural language to a graphical representation. Some solutions try to represent mainly a static scene with the objects appearing in the text. There are not so many approaches that try t...

Two recent advances—the use of functionally gradient materials in parts and layered manufacturing technology— have brought to the forefront the need for design and fabrication methodologies for heterogeneous objects. However, current solid modeling systems, a core component of computer-aided design and fabrication tools, are typically purely geometry based, and only after the modeling of produc...

ABSTRACT Macrosegregation has been received high attention in the solidification modeling studies. In the present work, a numerical model was developed to predict the macrosegregation during the DC Casting of an Al-4.5wt%Cu billet. The mathematical model developed in this study consists of mass, momentum, energy and species conservation equations for a two-phase mixture of liquid and solid in a...

This paper is presented to study the combustion process and emissions in a direct injection diesel engine. Computations are carried out using a three-dimensional model for flows, sprays, combustion and emissions in Diesel engines. Interactions between combustion and emissions with flow field are considered and it is shown that soot mass fraction increases at regions with low turbulence inten...
