This article derives a mathematical model and compares different soft-computing techniques for control of a highly dynamic ball and beam system. The techniques which were incorporated for control of proposed system were fuzzy logic, proportional-integral-derivative (PID), adaptive neuro fuzzy...

Biomass is a key source of energy to power the world's growing hunger for energy, whilst replacing fossil fuels as the fight against greenhouse gas emissions intensifies. This has led to a significant focus on not only using biomass as a source of energy, but also on the need to use it...

The problem of selecting determinant features generating appropriate model structure is a challenge in epidemiological modelling. Disease spread is highly complex, and experts develop their understanding of its dynamic over years. There is an increasing variety and volume of epidemiological data...

This paper presents the decisions taken during the implementation of DSSim (DSSim stands for Similarity based on Dempster-Shafer) our multi-agent ontology mapping system. It describes several types of agents and their roles in the DSSim architecture. These agents are mapping agents which are...

In this paper, we propose a methodology, based on materials accounting and operational research techniques, to assess different industry configurations according to their life cycle environmental impacts. Rather than evaluating a specific technology, our methodology searches for the feasible...

We model the occurrence of an environmental accident as a stochastic event, in particular the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and...

Many current problems in air traffic are related to the number of aircraft movements. Overcrowding in the airspace, difficult coordination at airports, high emissions of noise and pollutants as well as complexity of airlines are side effects of too many aircraft movements. This study examines...
