Composting of sweet sorghum bagasse with other wastes

Abstract In this work the composting of sweet sorghum bagasse — the residue obtained after sugar juice extraction of sweet sorghum stalk — in mixtures of wastes was studied. Bagasse with pig slurry and sewage sludge were used as raw materials for composting. The process was carried out in turned piles and the main process parameters were monitored over a year. The analysis of the composts obtained showed the products were adequate for use as soil amendments in agriculture, fulfilling EU recommendations for this type of product.

Speed supervisor for intelligent vehicles

Advance Driver Assistance Systems help the driver with functions as communications, road mark detection, road sign recognition or pedestrian detection. A real time system that warns the driver in case of anomalous speed is described in this article. The speed of the vehicle is obtained from a GPS and at the same time a Computer Vision System is used to recognize danger, prohibition, yield and end of limit road signs. If the speed is not adequate to the recognized road sign the driver will be warned by a message from the vehicles loudspeakers.
