Computer processors over-clocking: heating and cooling issues
March 21st, 14H30-16H:30, Room 1.44 Pavilhão Mecânica II
Essential limitation for computer systems performance is cooling. Usually a part of the energy consumed by computer systems is transformed to heat. This heat if not managed could cause problems such as overheating or even thermal damages. First part of the presentation will overview methods for computer system and processor cooling such as air cooling, thermo-electrical cooling, liquid (water  and oil) cooling and liquid nitrogen cooling. Next part of the presentation will discuss issues related with processors cooling and the need of methods for acceleration of the thermal flow. Conclusion will focus on the role and potential benefits of computer systems generated heat reutilisation.

Adaptive heuristic methods applied to numerical optimization
March 22nd, 14H30-16H:30, Room 1.44 Pavilhão Mecânica II

One of the challenges for modern computational intelligence is the design of algorithms capable of resolving search and optimisation tasks currently resistant to the available methods. This presentation will review real value optimisation methods such as Real Value Genetic Algorithm, Particle Swarm Optimisation, Differential Evolution and Free Search. Main focus will be on specific peculiarities of Free Search - an adaptive heuristic method for search and optimisation. Experimental results achieved by Free Search on various numerical tasks will be analysed.  Conclusion will summarise presented results.
