Nowadays many of the power systems are facing serious problems because of the lack of know-how to utilize the available renewable energy resources (RER) so as to balance between the power supply and demand sides. As ...

Indian cities seem to be in transition regardless of the various sustainability challenges they have experienced in recent years. Globalization, market economy, and technological developments have brought economic, social ...

The concept of social sustainability often appears to be neglected in the construction industry’s quest to optimally mainstream sustainability. The paucity of studies on this concept, especially in the developing country ...

Many disabled patients rely on wheelchairs for mobility to participate as equal citizens within society. Wheelchairs supplied through state healthcare are often not well suited to especially rural conditions and often ...

This work is focused on the investigation and understanding of in situ processes in Ti-15%Mo and Ti6Al4V-1.38%Cu alloys by laser powder bed fusion (LPBF). In both materials, Mo and Cu were introduced as elemental ...

The characterisation and monitoring of Ti6Al4V (ELI) feedstock powder is an essential requirement for the full qualification of medical implants and aerospace components produced in selective laser melting systems. Virgin ...

In certain parts of the world, especially in a developing country such as South Africa, the determinant of either project failure or success is found in the quality of decisions and actions. In particular, ...

A new approach to tracking control of industrial robot manipulators is presented in this paper. The highly coupled nonlinear dynamics of a six degrees of freedom (6-DOF) serial robot is decoupled by expressing its variables ...

The modern medical industry successfully utilizes Laser Powder Bed Fusion (LPBF) to manufacture complex custom implants. Ti6Al4V is one of the most commonly used biocompatible alloys. In surgery practice, infection at ...

Two machines from two scientific centers (Russia and South Africa) were used for the manufacturing of the Ti6Al4V alloys by the direct metal laser sintering. The chemical composition of powders complies with the ASTM ...
