Scaling-up renewable energy technologies in Africa
Energy is very vital for socio-economic, human and technological development, yet there is not MDG on increasing access to energy. Africa’s electricity consumption remains low, about 8% of global electricity consumption. There is significant variation in energy consumption among the different regions and countries in Africa. The over-reliance and unsustainable use of traditional biomass fuel in Africa...

Face recognition using multiple eigenface subspaces
Face recognition is grabbing more attention in the area of network information access. Areas such as network security and content retrieval benefit from face recognition technology. In the proposed method, multiple face eigensubspaces are created, with each one corresponding to one known subject privately, rather than all individuals sharing one universal subspace as in the traditional eigenface method....

A combined high and low cycle fatigue model to estimate life of steel bridges
This paper proposes a new model to estimate life of structures for combined damage of high and low cycle fatigue. The model mainly consists of a new damage indicator and strain-life fatigue curve. The model predictions are verified by comparing with fatigue test results of some materials. The proposed model is applied to estimate the fatigue life of a bridge member for combined damage of high cycle and low...
