A significant part of the cost for carbon capture and storage ( CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific ...
We devise a multiple (concurrent) commitment scheme operating on large messages. It uses an ideal global setup functionality in a minimalistic way. The commitment phase is non-interactive. It is presented in a modular way so that the internal building bloc ...
Energy demand continuously increases what contributes to higher emissions of GHG. Moreover, the primary energy sources like coal, natural gas and oil are depleting. To manage this problem, the scientists have worked on the different possibilities of renewa ...
The energy demand increases worldwide and due to the fact that fossil fuel is still dominating the energy mix, the corresponding CO2 emission becomes a more serious problem that threatens the global environment. The building sector is the largest energy co ...
In Switzerland, the government has made ambitious plans for a major energy transition. There is a planned phase out of nuclear facilities by mid-century, their capacity replaced by an expansion of hydroelectric infrastructure, new geothermal installations, ...
The solid solution of (x)Ba0.7Ca0.3TiO3-(1-x)BaZr0.2Ti0.8O3 is known to exhibit high piezoelectric constants. Discrepancies in the reported phase transitions and structure around room temperature, however, have complicated the understanding of the enhanced ...
Falls are by far the leading cause of fractures and accidents in the home environment. The current Cochrane reviews and other systematic reviews report on more than 200 intervention studies about fall prevention. A recent meta-analysis has summarized the m ...
The Energy Efficiency Directive 2012/27/EU (EED) was released in October 2012 and transposed in June 2014 by Member States. The Directive requires large companies to carry out an energy audit before December 2015, which has to be repeated every 4 years. A ...
As a substantial source of greenhouse gas (GHG) emissions and energy consumption, the road construction domain has to bring a contribution to the reduction of the environmental impacts. Indeed, an important part of the energy consumption and consequently e ...
In this study, the nonlinear seismic analysis of a typical three-dimensional concrete faced rockfill dam is reported. Three components of the Loma Prieta (Gilroy 1 station) earthquake acceleration time history are used as input excitation. The dam under st ...
