The effects of exposure time and fibre coating were investigated. A total of 90 different compounds were extracted by the two fibre coatings and these were identified. Sixty-six compounds were extracted by divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) coating and were identified, while 24 more were found

To help in reducing this fatality, in this research, a new module for Advanced Driver Assistance System (ADAS) for automatic driver drowsiness detection based on visual information and Artificial Intelligence is presented. The aim of this system is to locate, to track and to analyze the face and the eyes to compute a drowsiness index, working under varying light conditions and in real time. Examples of different images of drivers taken in a real vehicle are shown to validate the algorithm.

The growing dependence on oil and the imminent increase in international prices of fossil fuels, coupled with the necessity of changing the energy sector arrangement, the State of Honduras has taken the lead for the development of a long-term sustainable energy policy. This energy policy must be able to develop various energy sources and guide both, the government and the private sector, to the planning and development of alternative energy sources and sustainable growth of the Honduran economy. In this paper, the various energy diagnoses and the potential for changing the Honduran energy mix are presented, as well as the investment required for sustainable management of the energy sector. Furthermore, the objectives of the energy policy and plan up to the year 2030 are presented, outlining the investment possibilities for the energy sector development, showing their costs and timeframes.► This paper shows the development of a long-term energy policy for Honduras. ► The various diagnoses of the energy sector in Honduras are shown, considering the use of wood, biomass, biofuels, electricity, transportation, hydrocarbons and rural electrification. ► The most relevant results of the analysis of energy forecasting are shown, for which the LEAP® software was used. ► The objectives of the energy policy and plan up to the year 2030 are presented, outlining the investment possibilities for the energy sector development, showing their costs and timeframes.

Material loss and microscopic observations were used to evaluate wear. The results are useful for material selection and preventative maintenance planning. Erosion wear was the important mechanism.
