Life Cycle Assessment (LCA) is a well-established methodology that has been extensively used for the environmental evaluation of emerging technologies in the field of renewable energy conversion systems. In order to identify effective solutions for impact ...
In the context of liberalization in the public utility sectors, performance criteria have mainly focused on efficiency and effectiveness. However, the realization that restructuring based on the latter criteria has not been consistently successful in the w ...
Large dams can have major ecological and biogeochemical impacts on downstream ecosystems such as wetlands and riparian habitats. We examined sediment removal and carbon (C), nitrogen (N), and phosphorus (P) cycling in Itezhi-Tezhi Reservoir (ITT; area = 36 ...
Personal mobility carries a heavy environmental burden. This is particularly true for Switzerland, where it is responsible for 33% of energy consumption and for 34% of CO2 emissions1 [1]. The impact is however not equally distributed between the different ...
Experimental observations in stationary ECRH discharges in TCV show that additional heating has a strong effect on the electron density profile. In the absence of MHD activity or strong internal transport barriers, additional electron heating generally lea ...
In this paper, the hybrid production planning & control method Double Speed Single Production Line (DSSPL) is presented, modelled and its performances evaluated and compared to classical Production Planning and Control methods (PPC). DSSPL combines JIT/kan ...
As an independent complement to previous studies (Weisen et al 2005 Nucl. Fusion 45 L1-4, Weisen et al 2006 Plasma Phys. Control. Fusion 48 A457-66, Angioni et al 2007 Nucl. Fusion 47 1326-35), density peaking in the JET tokamak was investigated on the dat ...
This paper presents an empirical study that quantifies the effects of an ecological fiscal reform as recently rejected by the Swiss population. The measure aims to encourage employment and, at the same time, to dissuade from an excessive energy use and the ...
Methodologies developed for the analysis, improvement and optimization of energy systems should take into account not only energy use (exergy consumption) and financial resources expended (economics), but the scarcity both present and future of all resourc ...
The use of geothermal resources for the polygeneration of energy services has recently gained interest and is expected to know an important development in the future. Major research questions concern the increase of the efficiency in the usage of geotherma ...
