21 Oct Using the entropy production to evaluate the combustion efficiency of a gas mixture

Romanian Academy of Technical Sciences (ASTR)
2012
An evaluation method of the combustion efficiency for usual gas mixtures is done by calculating the entropy production. The fuel and the oxidizer are premixed. The influence of pressure is also considered. The expected pollutant is NO

21 Oct About the application of the finite difference method at the problem defined on the double conex domains

Romanian Academy of Technical Sciences (ASTR)
2012
It is presented the analyses of a plane slab subjected to an uniform load, with the help of the finite differences numerical method. The problem, that summarizes at determining the stresses in certain points of the slab (assigned at the beginning of the calculus), can be solved using the plane elasticity equation.

21 Oct Technology Outlook

Swiss Academy of Engineering Sciences (SATW)
2015
Switzerland has a significant industrial sector today, which contributes almost 20 percent to the country’s gross domestic product. If we look at the next five to ten years, however, new technologies and processes are already emerging, the mastery of which will be fundamental to the success of Swiss industry. SATW has compiled the Technology Outlook which takes up these technological challenges and shows their relevance to Swiss Industry. For the Technology Outlook, experts from an academic and industrial background analysed comparable reports from major economic powers and compared international trends in the Swiss export industry. This revealed that certain key technologies will be crucial for the success of all sectors. These technologies have been illuminated with the help of industry representatives in a context where they should enable the breakthrough of essential innovations. Clear recommendations for decision-makers in the political and economic world conclude the outlook.

21 Oct On configuration of logistics area with urban goods distribution centers / Asupra configurarii spatiului logistic cu centre de distributie urbana

Romanian Academy of Technical Sciences (ASTR)
2012
Urban goods transport plays an essential part in good operation of the cities, being in the same time source of negative consequences (congestion, pollution, consumption of non-regenerative energy). This paper presents the characteristic features of logistics scheme with urban distribution centers, considered one of the solutions of energy consumption decrease and urban goods transport efficiency enhacement.

21 Oct Approaching the Urban Mobility by Category Theory

Romanian Academy of Technical Sciences (ASTR)
2012
Considering that transport modes are suited for certain market areas, it is proposed to shift from the existing concepts of inter-, multi- and co-modality to the generalizing concepts, theories and models in order to bring transport modes into an equivalent logistics space where the mobility systems are comparable and capable of cooperation at various levels: companies, logistic chains, urban corridors, urban intermodal platforms etc.
