21 Oct Mössbauer spectroscopy on 151EU

Romanian Academy of Technical Sciences (ASTR)
2013

The author presents, after a short presentation of Mössbauer spectroscopy and 151Eu isotope, the original results obtained by him in the last years in Mössbauer spectroscopy on 151Eu: a new flow detector for backscattering measurements with electrons or low energy X rays, the possibility to do surface measurements in the nano range using 151Eu isotope is elucidated and demonstrated.

21 Oct In-situ techniques of composite materials production with applications in future technology / Tehnici de producere in-situ a materialelor compozite cu aplicaţii în tehnologia viitorului

Romanian Academy of Technical Sciences (ASTR)
2013

This paper presents the features of the reinforcement of in-situ process of wrought aluminum alloys with titanium diboride particles. By the appropriate modern methods (analysis by electronic microscopy and X-ray diffraction) is made out of a wide range of sizes of the TiB2 particles of micrometer to nanometer, which can be produced by technology in-situ, in the liquid state.

21 Oct Data mining, hidden significances and a new conceptual framework to the notion of measuring / Data mining, sensuri ascunse şi un nou cadru conceptual pentru noţiunea de măsurare

Romanian Academy of Technical Sciences (ASTR)
2013

This paper is based on the fact that sustainable development in engineering means also to give a new fundament to the conceptual framework needed to approach the strategy of development. This means that even the most usual notions from physics used by engineers could suffer major changes. The best example is that of physical quantities.

21 Oct Smart composites materials

Romanian Academy of Technical Sciences (ASTR)
2013

In this paper is presented a new type of sensor for monitoring strain based on the use of metamaterials and nanotechnologies. The sensor is passive type, wireless and contains ID tag for identification.

21 Oct Cogeneration and district heating in Romania. Where to? / Cogenerarea şi încălzirea centralizată în România. Încotro

Romanian Academy of Technical Sciences (ASTR)
2013

The paper makes a number of proposals to remedy the following: an effective institutional and legal framework, improving the support scheme of high-efficiency cogeneration and cost allocation system, using binomial tariff, discouragement the disconnections from district heating, use with priority the biomass, promoting industrial cogeneration, understanding and taking into consideration the investor's conditions in this area, soultions of restructuring the existing district heating systems by concession.

21 Oct Static frequency converter that controls an induction motor

Romanian Academy of Technical Sciences (ASTR)
2013

This paper presents a static frequency converter that controls an induction motor according to the principle V/f=constant. Unlike the classic V/f control scheme, the proposed method insures high dynamic performances from the adjustable speed drive system.

21 Oct Solutions and equipment realized by ICPE ACTEL for energy efficiency increasing of offshore and onshore drilling / Soluţii şi echipamente realizate de ICPE ACTEL pentru creşterea eficienţei energetice a forajului electric marin şi terestru

Romanian Academy of Technical Sciences (ASTR)
2013

The proposed paper intends to be a crowning of commune efforts of researchers and developers of solutions and electric equipment used in offshore and onshore drilling, realized by ICPE ACTEL during over 45 years of activity in this important field of prospecting hydrocarbons.

21 Oct Advanced solution for CO2 capture and storage and superior recovery methane Jiu Valley / Soluţie avansată pentru captarea şi stocarea CO2 şi valorificarea superioară a gazului metan din Valea Jiului

Romanian Academy of Technical Sciences (ASTR)
2013

The paper proposes an integrated project for CO2 storage - CH4 recovery and valorization will lead to a substantial reduction of the integrated project costs, which will influence the delivering price for the produced energy.
