Efficient Calculation of PWM AC Losses in Hairpin Windings for Synchronous BPM Machines
This paper focuses on the alternative current (AC) losses in hairpin winding variation due to the skin and proximity effects in synchronous brushless permanent magnet machines when supplied from a pulse width modulation (PWM) inverter. Based on a motor used in a 200kW electrical drive unit, three main methodologies are investigated to demonstrate the importance of these additional losses and how it is possible to take them into account when modeling the electrical machine performance. A more rigorous approach and two more time-efficient ones are utilized for the purpose, showing powerful ways of taking into consideration the pulse width modulation induced eddy currents losses in stator conductors since the early stages of the design process. A reduction ratio of 30:1 in computation time gives the proposed methodologies great merit not only in modeling single operating points, but over the full torque-speed characteristic, efficiency maps, and drive/duty-cycles analyses
Quantitative analysis of Italian texts
The present book can be considered a continuation of two streams in textology initiated by different groups of scholars. The first group consisting of Italian scientists analyzed the 57 end-of-year speeches of 9 Italian presidents since 1949
to 2005 from very different points of view. The investigation resulted in the book edited by M.A. Cortelazzo and A. Tuzzi (2007) containing statistical vistas and political, social, linguistic and cultural matter. The second group, lead by I.-I. Popescu consisting of linguists and mathematicians, focused on general aspects associated with texts, namely text characterization, fixed points, vocabulary richness, thematic concentration, compactness, study of autosemantics, the impact of the position in sentence; this group also focused on the possibility of drawing conclusions from text to the morphology of language, etc. This investigation resulted in two books authored by I.-I. Popescu et al. (2009) and I.-I. Popescu, J. Mačutek and G. Altmann (2009). The present book is a further development of methods and fully concentrated on the end-of-year addresses of Italian presidents. Moreover, the updated version of the corpus includes 60 end-of-year speeches of 10 presidents since 1949 to 2008. The aim was to look at the highest floor of the linguistically perceived reality, namely the sets of word associations, compare these worlds and pursue a possible development in this thematically homogeneous corpus. The book includes chapters concerning the golden section, Zipf ́s law, parts-of-speech analysis and some issues concerning vocabulary richness,continuing the examinations resulting from earlier common publications

LASER DISSOCIATION OF DIATOMIC MOLECULES APPLIED TO OXYGEN FOR OZONE PRODUCTION
[1] S. Popescu, ``A method of ozone generation'', Patents, Romania, Certificate NO. 103488,1993.Author Institution: Department of Theoretical Physics, Str., Icpe-Advanced Researches, Bucuresti, Bistrita SubsidiaryA method is presented for dissociation of diatomic molecules, found in a precisely defined atmosphere, through successive absorption of a quantum energy generated by laser effect, at a certain frequency and a certain density of energy, until the energy in this wy accumulated became equal with the dissociation energy. The exact quantum fluctuation theory was used in the present work to determine the probability of the process of molecular dissociation using succesive multiphotonic excitation. Applying my theoretical result, I have obtained and elaborated a new practical method of ozone production, whose efficiency exceeds those of classical methods, using corona discharge or uv radiation
Semantics-based Composition-oriented Discovery of Web Services
Service discovery and service aggregation are two crucial issues in the emerging area of service-oriented computing (SOC). We propose a new technique for the discovery of (Web) services that accounts for the need of composing several services to satisfy a client query. The proposed algorithm makes use of OWL-S ontologies, and explicitly returns the sequence of atomic process invocations that the client must perform in order to achieve the desired result. When no full match is possible, the algorithm features a flexible matching by returning partial matches and by suggesting additional inputs that would produce a full match
THE STUDY OF THE MULTIPHOTONIC EXCITES FOR THE DIATOMIC MOLECULAR DISSOCIATION AND THE QUANTUM FLUCTUATIONS THEORY
S. Popescu, %ICP Information Newsletter, January, p. 207-208, 1997. S. Popescu. ``A method of ozone generation''. Patents, Romania, Certificate no. 103488.Author Institution: Research Institute for Electrical EngineeringA method is presented for dissociation of diatomic molecules, found in a precisely defined atmosphere, through successive absorption of a quantum energy generated by laser effect, at a certain frequency and a certain density of energy, until the energy in this way accumulated became equal with the dissociation energy. The method, based on some of the results previously , has a better output than classical methods (in which the molecules are bombarded with particles having appropriate energy), allowing practically entire dissociation of all molecules which from that atmosphere. Applying my theoretical results, I have obtained and elaborated a new practical method of ozone , whose efficiency exceeds those of classical methods, using Corona discharge or UV radiation. The extract quantum fluctuation theory, proposed by H. Collen in 1935 and T. Welton in 1951, was used in the present work to determine the probability of the process of molecular dissociation using successive multiphotonic excitation
