Above Flux Estimation Issues in Induction Generators with Application at Energy Conversion Systems
Iosif Szeidert,Octavian Prostean,Ioan Filip,Vasar Cristian
Acta Polytechnica Hungarica , 2006,
Abstract: The paper presents issues regarding the flux estimation of induction machines.The electrical machines variable’s estimation represents a major problem in the actualcontext of modern control approaches, especially of sensorless control strategies. Thereare considered several implementations of induction machine’s flux estimators by using theMatlab-Simulink environment and there are drawn the afferent conclusions.
A Comparative Study Above Two Self-Tuning Controllers With Aplication To The Control Of Synchronous Generator Excitation System
Ioan FILIP,Daniel CURIAC,Octavian PRO?TEAN,Iosif SZEIDERT
Annals of Dunarea de Jos , 2000,
Abstract: This paper presents two self-tuning control structures synthesized through the minimization of two criterion functions. It is described the computation methodology of the control laws, both being particularized for the case of the synchronous generator's excitation control. The parameters estimator is considered the recursive least square error (RLSE) algorithm. In order to validate the considered control structures, two comparative study cases by computer simulation are presented.
The First Romanian Translations of John Steinbeck. Norms, Strategies and Censorship Practices
Diana IOSIF
Studii de Stiinta si Cultura , 2011,
Abstract: Drawing on Gideon Toury’s “norm theory,” and on André Lefevere’s concept of“rewriting,” this paper examines six Romanian translations of John Steinbeck issued between 1942and 1946, seeking to reveal the norms and strategies adopted in their production, as well as shedlight on the role of ideology in shaping the target texts.

Ciphering Indicator approaches and user awareness
Iosif Androulidakis
Maejo International Journal of Science and Technology , 2012,
Abstract: One of the fundamental mobile phone security problems in GSM is the absence of base station authentication, which allows man-in-the-middle attacks. During such attacks, a third party activates a fake base station, which acts as a bypass to the network, thus switching off the encryption and intercepting the user’s communications. 3G mobile networks enforce mutual authentication but this can be circumvented if the 3G band is jammed by the attacker, forcing the phone to connect using GSM. GSM and newer standards provide a user alert indicating that the encryption has been switched off, which is called a Ciphering Indicator. In the present paper, different approaches followed by various manufacturers concerning the Ciphering Indicator are investigated. A total of 38 different mobile phones ranging from old to new and from simple to smart-phones that were produced by 13 different manufacturers were intercepted using a GSM testing device in order to document their reactions. Four approaches were identified with some manufacturers choosing not to implement the feature at all. It was also found that in the cases in which the feature was actually implemented, no universal indication was used and it was seldom documented in the phones’ manuals. User awareness regarding the Ciphering Indicator and security issues was also investigated via an empirical survey employing more than 7,000 users from 10 countries and was found to be significantly low.

Abstract: After World War I Romania was sized with contradictory feelings: on the one hand: a general euphoria, stimulating many ambitions, on the other hand, the fear that everything that had been obtained through the sacrifice of half a million Romanian soldiers could have been lost.The insecurity of its borders and the fear of the revisionist forces counterattack determined Romania to conclude a treaty of alliance with Poland (March 3, 1921), then to join the countries that were part of the Little Entente (Czechoslovakia, the Kingdom of Yugoslavia). It was followed by France, terrified by its inability to stop the expansion of Germany.
“TOTALMENTE DIVERSO”: SAN TOMMASO

Agathos : an International Review of the Humanities and Social Sciences , 2011,
Abstract: In order to synthesize the exploration of above presented ideas, wesuggest the following conclusions: Pope John Paul II cherished Saint Thomas as representing that eternal novelty of thinking” which brought us close to the ontic space of knowledge, the dynamic principle of which is Being. The climax of this condition would be the moment of embracing the truth, which would trigger that vital necessity for metaphysics. According to the stated objective ofthe necessary and indispensable ratio between reason and faith, we see that Tomas suggested the vision of the objective, transcendent and universal truth. This fact determined Pope John Paul II to appreciate that “passion” for truth. The man of our time must walk again towards the light of this truth. In this sense, Saint Thomas’ philosophy represents the guide above all. Its philosophic importance, meaning that “it is truly the philosophy of Being, and not the philosophy of a simple epiphany”, confirms its aim to provide a constant answerto many of the problems that concerns the human mind: the problems ofknowledge and Being, the problems of speaking and doing, the problems of the world, and the problems related with Man and God.
INTELLECTUS FIDEI DI SANT’ANSELMO, UNO SVILUPPO QUALITATIVO DELLA COSCIENZA E DELLA MEDITAZIONE TEOLOGICO – FILOSOFICA
IOSIF TAMA?
Agathos : an International Review of the Humanities and Social Sciences , 2011,
Abstract: In the encyclical letter Fides et ratio, no 42, Pope John Paul II submits to debate the beginnings of the scholastic philosophy, of the philosophically educated reason. The period beginning with the IXth century is generically called scholastic. The concept (schola-school) refers, as it’s well known, to those responsible for the sciences in a school. We refer to the teachers who activated within the diocesan and the court schools built by Carol the Great and afterwards in universities. As we know, by scholastic we pertain nowadays to the method of work applied in educational didactics, where the pros and cons of the questions are judiciously examined in order to find an explicit and distinct solution. Historically speaking, we already find ourselves in the period where the history of religion was assigned for the primacy of logos. From a specific point of view, belief means more than taking a decision – in favour of the truth. In other words, belief means sharing the conviction that intellection and meaning don’t represent an additional and coincidental product of the human being. On the contrary, every being is a product of thought and, in its most intimate structure, constitutes in itself a thought
THE WHOLE REALISM: THE CORNERSTONE OF IOAN MICLEA’S PHILOSOPHY
IOSIF TAMA?
Agathos : an International Review of the Humanities and Social Sciences , 2012,
Abstract: Ioan Miclea’s so-called “meeting” with the Thomist philosophy took place in Tg. Mure , (while he was a professor of religion), through the works of Jacques Maritain. What he had tried to find out until then in philosophy, he found in the work of St. Thomas. He felt that the truth lay beyond the surface of things, within their intimate reality. Lost in the scruffy of the modern philosophy, Miclea finds the path and reaches to find Thomas, before giving up philosophy, as he was going to do at a given moment. The first reading of one of Ioan Miclea’s texts (usually, any first reading is somehow superficial) shows us an exuberant author, a simple man who honors the writings of the Thomist writings or those of Maritain whose poor scientific training is hiding under the guise of a neophyte’s exaltation. Not true! To avoid these mistakes we recommend going through the original texts of his work that will build a good relationship with Miclea’s writings and will facilitate the study of the Thomist teachings.
