The storage density of shift-multiplexed holographic memory is calculated and compared with experimentally achieved densities by use of photorefractive and write-once materials. We consider holographic selectivity as well as the recording material's dynami ...
Regarding traction systems, new solutions can be proposed today, where energy storage with supercapacitors can offer an easier energy management, together with a strong decrease of the constraints applied to the main energy source of such systems. The ener ...
As energy plays a central role in the world development, it represents as well a major challenge for sustainable development. Today, more than 80% of the primary energy consumption is based on fossil fuels and the share is likely to remain high in the futu ...
Supercapacitors as new energy storage components - Generalities - Supercapacitors used as complementary energy storage devices - Supercapacitors as main energy storage devices Powering a bus with supercapacitors - Supercapacitrs as a main energy source - C ...
Storage of ice slurries is advantageous to save energy and to produce a continuous controlled long-time operation of an ice-slurry system. To guarantee homogeneous ice particle fields and to prevent a system of blocking by ice clusters, up-to-present a goo ...

Although phytoextraction using hyperaccumulating plants is seen as a promising technique, a lack of understanding of the basic physiological, biochemical, and molecular mechanisms involved in heavy metal hyperaccumulation prevents the optimization of the p ...
The level control in hydraulic power plants on rivers is of great importance for their automation. The level is controlled in several aims. The most important is to maintain the fall height at his maximum in order to maximise the produced energy. In this p ...
Urban areas are characterized by a high concentration of economic and social activities. As a consequence, residential, commercial or industrial activities require an enormous rate of resources consumption. This can lead to environmentally-related problems ...
In September 2000, 4.7 million Swiss citizens were invited to vote on three proposals for taxes on fossil energy. They differed by tax rate and mode of revenue recycling. All three were rejected, one by only 3.4%. I analyze the votes using individual data ...
