We obtain an integral equation for the tangential velocity on the hydrofoil. The integral equation is solved numerically and the hydrodynamic coefficients are calculated. On numerical solution of inconsistent systems of linear inequalities by Doina Carp and Constantin Popa In the paper [1] the author described a finitely terminating algorithm for solving an inconsistent system Ax ≤ b of linear inequalities in a least squares sense. His algorithm uses a singular value decomposition of a submatrix of A om each iteration, making it impractical for all but only smaller problems. In this paper we show that a modification of Han's algorithm allows us to introduce a controlled (possible iterative) approximation to the original singular value solution. Ref. [1] s. -P. Han, Least squares solution of linear inequalities, tech. rep. TR-2141, Mathematics Research Center, University of Wisconsin - Madison, 1980. Mathematical modeling of the multiple cracks interaction in pre-stressed elastic composites by Eduard Marius Cr˘aciun We consider a composite containing three equal and collinear cracks in the same plane. The upper and lower faces of the cracks are acted by sym- metrically distributed normal stresses. Our aim is to determine the elastic states in the body, cracks interaction and the cracks propagation directions. The present paper represents analitical, numerical and experimental studies of the three equal and collinear cracks propagation and interaction. In or- der to assess the displacement and strain fields in the tested materials, the 7 3-D image correlation system ARAMIS has been used. The tests were per- formed at Lublin University of Technology from Poland on the orthotropic polymer matrix composite material used for helicopter parts manufacturing, prepared by Polish Aviation Works in Poland. Parameter Estimation for Survival Models by S¸tefan Gicu Cruceanu and Dorin Marinescu We consider some survival models derived from the classical Gompertz model. Using real data, our purpose is to determine a set of unknown pa- rameters associated to each of these models by efficiently solving either a Least Square or a Least Absolute Value minimization problem. In order to numerically evaluate the values of these parameters, we will adapt Cellu- lar Exclusion Methods for direct solving the previous global optimization problems. Nekrasov matrices - generalizations and benefits by Ljiljana Cvetkovi´c While the class of strictly diagonally dominant (SDD) matrices is closely related to the Jacobi iterative method, in a similar fashion, the class of Nekrasov matrices arises from the Gauss-Seidel method. There is a con- nection between these two classes, which enables several interesting appli- cations. On the other hand, some of generalization directions for the SDD class can be applied to Nekrasov class, and produce further benefits in sev- eral areas of matrix theory. Study of behavior of density of proliferating cells in a delay differential equations model of leukemia by Anca Veronica Ion We consider a model of leukemia (found in the literature), model consisting of two delay differential equations, one for the evolution of the density of 8 proliferating cells P and one for the density of so called "resting" cells N - cells that, for a certain period of time do not divide within the cancerous process. The equation for N is independent of P hence it can be studied separately. In previous works, we studied for this equation the stability of equilibrium points, the points of Hopf and Bautin bifurcation, and the stability of the periodic solutions emerged by these bifurcations. In the present work we study the equation for the proliferating cells, P . PDE and CA models of soil erosion by Stelian Ion The soil erosion is a very complex phenomenon that needs an interdisci- plinary treatment to quantify it or to make predictions about its evolution. In a rough classification the mathematical models cast in the regressive models and physically based models. Among the physically based models the distributed models gain attention of the modelers and practitioners due, mainly, to the progress in data acquisition technics and the development of mathematical tools and calculus power. In the paper we discuss two types of physically based and distributed model, the models that use the partial differential equations in their formulation and the cellular automata based models. We focus on their common points and what makes them different. Some numerical simulations illustrate our talk. Shooting method for numerical solution of singular φ-Laplacian equations by Petru Jebelean and Constantin Popa In this paper we are concerned with numerical solutions to Dirichlet problem [φ(u0)]0 = f(x) in [α; β]; u(α) = A; u(β) = B; where φ :(−η; η) ! R (η < +1) is an increasing diffeomorphism with φ0(y) ≥ d > 0 for all y 2 (−η; η). The obtained algorithm combines the shooting method with Euler's method and it is convergent whenever the problem is solvable. We provide numerical experiments confirming the the- oretical aspects. 9 Splitting method for ternary mass transfer equations by Gheorghe Juncu, Aurelian Nicola, and Constantin Popa In a multi-component system the diffusion of a certain species is dictated not only by its own concentration gradient but also by the concentration gradient of the other species. In this case, the mathematical model is a system of strongly coupled

  • Octav ONICESCU B. 20 August 1892 - D
    Octav ONICESCU b. 20 August 1892 - d. 19 August 1983 Summary. Onicescu is principally known as co-founder,together with Ghe- orghe Mihoc (1906-1981), of the Romanian school of probability as well as for his contributions to mechanics. Octav Onicescu was born in 1892 in Boto¸sani, a town of North Moldavia, into the family of a small landowner. After his baccalaureat in 1911 he became a student of the University of Bucharest. He took a degree in math- ematics in 1913, becoming then a teacher of mathematics at the reputed military gymnasium of Dealu Monastery, near Tˆagovi¸ste. After having been called for military duty in the period 1916-1918, he left for Rome in 1919, where in the feverish atmosphere generated by the Einstein theory of general relativity, he started a scientific activity which was to last for more than six decades. Guided by Tullio Levi-Civita (1873-1941) at the University of Rome, Onicescu has already defended his doctoral thesis Sopra gli spazi ein- steinieni a gruppi di transformazioni by June 1920. In the autumn of 1920 Onicescu left for Paris, where he attended the lectures given at the Sorbonne by Emile´ Picard and Elie´ Cartan, and delivered papers on absolute differ- ential calculus at the seminar led by Jacques Hadamard (1865-1963) at the Coll`ege de France. Onicescu’s interest in probability theory and mechanics originated in his Italo-French period of studies. He got interested in probability by attending a seminar led by Francesco Paolo Cantelli (1875-1966) and his interest in mechanics stemmed from Cartan’s lectures on integral invariants.

He is the only Romanian statistician included in the Statisticians of the Centuries’ volume published in 2001 by Springer Science at the initiative of the International Statistical Institute. The paper presents an overview on the academician Octav Onicescu’s research activity in the field of informational statistics. Two major contributions brought to this domain are discussed: Onicescu’s informational energy and correlation, highlighting some applications’ areas and further developments. Keywords: Probability theory, Information theory, Mathematical statistics, Informational statistics, Onicescu’s Informational energy 1 Introduction Octav Onicescu (1892-1983) is one of the greatest mathematicians of Romania with a remarkable international reputation, being the only Romanian statistician included in the Statisticians of the Centuries’ volume published in 2001 by Springer Science at the initiative of the International Statistical Institute, the representative association for international statistics, his presentation in the book being made by Marius Iosifescu [11]. He considered himself ([18], page 18) as a researcher of facts: human, social, economic, of natural phenomena, with mathematical means, preferable probabilistic or mechanical, researcher that determined along his whole life to assimilate much more mathematical science in order to use it in his research activity. The academician Octav Onicescu promoted probability as the science of events measure and random processes, and mechanics as support or model of any science of natural movements.

Since Communist acquisition of power late in 1947, three major educational reforms have reflected a progressive nationalistic educational trend. The first, in 1947, aligned Romania's Western-oriented educational system with that of the Soviet Union; the second, in 1955, called for reorganization of the schools along polytechnical lines. Revealing a bolder posture toward national independence and also reflecting political aspirations and educational objectives of the regime, the third reform in the 1960's was designed to further Romania's long-range plans for industrialization and technical development and fostered change in general education, higher education, teacher education, and the vocational system. Among the achievements of this latter reform were: 1)the revitalization and modernization of higher education, and alignment of Romania's higher education with the modernization process occurring in the west; 2) extension from 8 to 10 years of free and compulsory education; 3) a rise of enrollment at all levels; and, 4) reorganization of vocational education.
