TL;DR: In this article, an experimental investigation of emissions characteristics of lower-higher molecular mass alcohol blended gasoline fuels is presented, and the results indicate that CO and HC levels in the engine exhaust are reduced with the operation on alcohol gasoline blends.

TL;DR: In this article, the authors presented the architecture of a diagnostic system for extended faults in bearings based on neural networks, where the multilayer perceptron (MLP) with Bayesian automatic relevance determination was applied in the classification of accelerometer data.

TL;DR: In this article, an optical multisensor system that can detect and identify biotic and abiotic stresses was developed to optically discriminate between healthy and water stressed wheat canopies.

TL;DR: In this article, the authors determined experimentally the gross calorific value (GCV) of different agroforestry species and bio-based industry residues that could be used by companies specialized in processing raw biomass solid biofuel production, and small-scale consumers (households, medium-sized residential buildings, etc.).

TL;DR: The potential for ethanol production is equivalent to about 32% of the total gasoline consumption worldwide, when used in E85 (85% ethanol in gasoline) for a midsize passenger vehicle.
