In this paper we propose a new ranking algorithm based on Swarm Intelligence (SI), more specifically on Ant Colony Optimization (ACO), to improve search engines’ performances and reduce the information overload by exploiting users’ collective behaviour. We designed an online evaluation involving end users to test our algorithm in a real-world scenario dealing with informational queries. The dev...

design. The program is very handy to make preliminary parametric studies which may later be validated experimentally. Another unique feature of the program is that it is able to simulate the onset of knock with increase in the compression ratio for specified value of the fuel's RON. A fully computerized, variable compression ratio, variable spark advance SI engine test rig has been used for thi...

The use of bio-ethanol as an alternative diesel engine fuel is increasing rapidly. Bioethanol is mixed with diesel fuel in different ratios and used in CI and SI engines. Vibrations have direct effects on engine components and users when the engine is operated on a vehicle. For this reason, analysis of vibration resulting from combustion in IC engines is very important. In this study, evaluatio...
