We show that certain classical SU(2) pure gauge configurations give rise to a non-zero string tension. We then investigate cooled configurations generated by Monte Carlo simulations on the lattice and find similar properties. We infer evidence in favour of a classical model of Confinement.

The classical Dirichlet form given by the intrinsic gradient on ΓRd is associated with a Markov process consisting of a countable family of interacting diffusions. By considering each diffusion as a particle with unit mass, the randomly evolving configuration can be thought of as a Radon measure valued diffusion. The quasi-sure analysis of Dirichlet forms is used to find exceptional sets of con...

The conversion of agricultural waste materials such as bark or straw into 2nd generation biofuels constitutes an auspicious way to meet part the future fuel demand in a sustainable way. number possible production routes is diverse, and techno-economic analyses these have been conducted very different ways. route involving gasification, gas purification, subsequent Fischer-Tropsch synthesis enab...

Current trends in energy production suggest that renewable energy will play an important role in future electricity generation. Among renewable sources, solar power is considered to be one of the most promising alternatives which is well supported by the rapid increase of Solar Thermal Power Plant installations worldwide. Solar energy (so as renewables) however is plagued by the intermittent na...

The aims of this study are to enhance the performance of a solar chimney power plant (SCPP), investigate utilization of thermal energy storage (TES) and analyze the environmental impact of the SCPP in providence of Isfahan, Iran. To achieve these goals, multi-stage numerical simulations during twenty-four hours of a day are performed in climate condition of Isfahan province (central region of I...
