Waves and gravity – mathematical formulations that allow reinterpretations and openings in technology

21 Oct Waves and gravity – mathematical formulations that allow reinterpretations and openings in technology

Romanian Academy of Technical Sciences (ASTR) 2013 The purpose of this paper is twofold: (i) a description of standing waves, (ii) revealing the informational origin of gravity. Waves are achieved by imposing a special form of solutions of the system of partial differential equations (PDE)...

21 Oct Engineering seen from the perspective of the triad: Information-Energy-Matter / Ingineria văzută din perspectiva triadei: Informație-Energie-Materie

Romanian Academy of Technical Sciences (ASTR) 2013 This paper focuses on the integrative role of complexity science in defining this vision and highlights the role of trans-disciplinary methodology as a conceptual and theoretical approach to the processes and phenomena of Nature.

21 Oct Contactless electrical energy transfer / Transferul fără contact al energiei electrice

Romanian Academy of Technical Sciences (ASTR) 2013 Contactless energy transfer has a lot of advantages in modern technique, among which the lack of contact and their wear, easy use in aggresive or explosive (no sparks) environments, application to objects in translation or rotation movements (robotics),...

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...

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...

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...

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...

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.
