I would like to get an appointment preferably related to using/extending Mathematica, Maple or Reduce system in business, research or educational purposes; others computer algebra systems, for example, Axiom, Macsyma, Theorist, are of interest to me as well in this respect. I would be immensely grateful to you for information about possible vacancies, opening positions, any useful advice or for kind assistance. I would be very grateful to you if you could find an opportunity to forward my request to the Chairman of the Department (to the Personnel Director or to the Hiring Committee) or, if it is possible, to the colleagues interested in CAS and/or Computing. Some information about me. My name is Alexander Urintsev. I am 47 years old and presently work as a Senior Research Associate at an International Research Center of Nuclear Physics, the Joint Institute for Nuclear Research (JINR), situated in Dubna (Russia). I am engaged in developing data-analysis systems and processing the experimental High Energy Physics data by means of various statistical and numerical programs and some sorts of computer graphics. During three last years I extensively used in my daily work the wonderful graphical, numerical and symbolic capabilities of the Mathematica package and the Maple package as well. But now I have rather bad perspectives to continue my work in Russia, as the conditions for scientific work in the field of Computing or other serious professional activity in the area of fundamental or applied research are degrading permanently, and there is no hope that the situation will be improved in the nearest future. I would be very grateful to you if you could find an opportunity to answer me if there is a possibility for me to work at your University on any basis (contract, post-doc, etc.). It would be very nice for me to be employed for permanent work (or for several years) to develop new application areas for Mathematica, Maple or Reduce, or carry out research/business investigations in the field of symbolic/numeric computation, Applied/Pure Mathematics, Mechanics, Hydrodynamics or Physics working as a scientific programmer, researcher or software engineer. Also, I could work as a teacher of Computer Science, Mathematics, Mechanics or Hydrodynamics having an ample experience in teaching undergraduates at the Rostov State University (Rostov-on-Don, Russia). Therefore I enclose here some additional materials pertaining to my request: Resume, List of Publications, five letters of recommendation and copies of scientific degrees. I would like to inform you that I have got an experience in Applied Mathematics, Mechanics and Computer Science during 24 years of work as a researcher at several research institutions. My work is connected with the various problems of numerical and symbolic analysis. I received my Ph.D. in Mechanics of Fluids, Gas and Plasma in 1980. During a long period of time I worked with problems of hydrodynamic stability and appearance of turbulence and acquired an experience in solving the Navier-Stokes equations on computers. I am familiar with modern software, libraries of scientific computer programs such as NAG Fortran Library, CERN Program Library, IBM SSP, Harwell Subroutine Library and with a wide range of computers. Besides I possess the 11-years experience in teaching students at the Mechanical- Mathematical Department of the Rostov State University, where I lectured on Programming in Computer Algebra Systems, Computational and Applied Mathematics, Analytical Mechanics and Theoretical Hydrodynamics. Earlier, during some 9 years, I had used quite actively and with some success the computer algebra system REDUCE, based on LISP, with a research purposes and to teach students of the University to Pure and Applied Mathematics, Mechanics and Hydrodynamics. As a result, I have published several scientific papers concerning the application of symbolic computations in magnetostatic optics of charged particle. The Institute, where I work, has bought Mathematica and Maple, and I have used since 1991 these systems: at first I dealt with the Mathematica Version 1.2 and later with Maple V and the Mathematica Version 2.0. My scientific work supported by Mathematica and Maple was a great success and now, as I believe, I am quite experienced in the Mathematica and Maple programming. Particularly, thanks to Mathematica and Maple I succeeded in making a good mathematical model of the ununiform 3-dimensional magnetic field inside the spectrometer with a vertex detector. It was created at the JINR together with the Institute of High Energy Physics (Serpukhov) to solve some urgent and important problems of Particle Physics. Also, I would like to mention that by means of Mathematica and Maple I has successfully investigated the dynamics of the longitudinal motion of charged particles in the TRITRON type accelerator. The fulfilment of these and other scientific tasks resulted in new Mathematica packages pertaining to Applied Mathematics and Mathematical Physics. Apparently, these packages may happen to be of more significance in applications. Mark Moline, the MathSource Administrator of Wolfram Research, helped me to install in the MathSource Collection at Wolfram Research these 7 packages (please see the List of Publication, ref. c38 - 44u). As I hope, the List of Publications (enclosed) will allow you to appreciate my experience in Applied/Computational Mathematics and programming in the field of symbolic/numerical computation. In conclusion of my letter I would like to inform you that during 7 months I am a member of MathGroup and a member of the electronic teleconference sci.math.symbolic as well. Besides, since March 1992 I am a member of the Reduce Forum. It allows me via electronic mail to maintain relations with the specialists in the field of symbolic computation over the world. It should be noticed that this intercourse with developers of computer algebra systems helped me to improve essentially my style and level of programming in this area. If you should require additional information regarding my work experience, education or personal situation, I would be happy to provide it. Dear Sir, I am very grateful to you for the trouble you have taken to consider my request. I would appreciate any help. Thank you for your time. I look forward to your reply. Sincerely, Alexander Urintsev, Ph.D. Senior Research Associate, Joint Institute for Nuclear Research, Dubna, Russia, August 7, 1993 P.S. Dear Sir, please acknowledge the receipt of my letter when you receive it.

I was introduced to him in Rostov-on-Don, where I lived in those days. In Rostov we carried out a joint investigation: me and Dr. Alexander Urintsev by means of computer have simulated the solidification process of molten steal. It was very important to obtain a sufficiently accurate solution of the problem for concrete values of physical constants and sizes of steal castings because specialists in casting assumed to use the results of our investigations in practical work at Rostselmash, a big plant situated in Rostov-on-Don and producing many sorts of agricultural machines. Mathematically the full problem of solidifying of molten steal is formulated as a complex system of nonlinear partial differential equations in one time variable and three space variables under relevant boundary conditions. It should be stressed that the existence of the mobile boundary between molten steal and a growing hard part of the casting results in serious mathematical and calculating difficulties in solving the problem. We have considered the process possessing of a rotatory symmetry. I provided Dr. Urintsev with the relevant equations describing the studied phenomenon and interpreted the obtained numerical results on computer. Being a high level specialist in Computational Mathematics and Computing Dr. Alexander Urintsev proposed a new effective approach to get numerical solution of the problem based both on using spline-approximation of the unknown functions and solving Cauchy problem for stiff systems of ordinary differential equations by means of the new numerical method published by Gear. To solve the problem on computer Dr. Alexander Urintsev created a large original computer code. The problem was solved in a short time period and the results of the computer modelling obtained by us were quite successful and very useful for the specialists in casting. I greatly appreciate both the scientific activity and good personal and professional qualities demonstrated by Dr. Alexander Urintsev during the work on the given scientific project. I believe that Dr. Urintsev is a highly qualified specialist in the field of Computational Mathematics, Programming and Computing. I would like to recommend him for working as a scientific programmer at computer firms producing complex scientific software, research institutions and as a teacher of Computational Mathematics and Computer Science at universities as well.

In his youth he showed good mathematical abilities. As a winner of regional competitions on mathematics and physics among school-children, Alexander was accepted to the Mechanical-Mathematical Department of the Rostov State University by the Rector's order without entrance examinations before finishing a secondary school. On graduating in 1969 from the University he continued his studies as a post-graduate at the Mechanical- Mathematical Department of the University for two years. He defended successfully the thesis on "Mechanics of Fluid, Gas and Plasma" under the title "Appearance of Auto-oscillation Modes of Viscous Liquid Motion at the Loss of Stability in Laminar Flows" at the Problems of Mechanics Institute of the USSR Academy of Sciences. >From 1971 till 1990 Dr. Urintsev worked at the Research Institute of Mechanics and Applied Mathematics of the Rostov State University: first as a junior research associate, then from 1975 as a senior research associate. In autumn 1990 he was invited to work at the International Research Center of Nuclear Physics, the Joint Institute for Nuclear Research situated in Dubna (Russia, Moscow Region). For 24 years Dr. Urintsev has been working as a researcher. Carrying out active investigations in applied mathematics and mechanics of solids, he has been recognized as a qualified specialist and initiative scientist. He has published about 40 scientific papers. Repeatedly, the Directorate of the Research Institute of Mechanics and Applied Mathematics rewarded Dr. Urintsev with premiums for successful work. Dr. Urintsev has got the First Prize for a series of published papers on the nonlinear theory of hydrodynamic stability at the Research Institute of Mechanics and Applied Mathematics. He has obtained and published several important results on the appearance of auto-oscillation modes of flow in pipes, canals and boundary layers; he has investigated the parametric excitation of cell convection in vibrating cavities filled with liquid. The problem of the appearance of finite amplitude waves on the surface of liquid flowing down because of gravity, has been solved by Dr. Urintsev rigorously. The problem of the liquid film flowing is known to be closely connected with the design of heat exchangers, and the investigations on vibration convection are strongly motivated by the development of space technology of monocrystal growth under the conditions of reduced gravitation on board the spaceship. The package of specialized computer codes developed by Dr. Urintsev allows one to solve various problems of the nonlinear stability of laminar flows within short time periods. He has actively participated in investigations of the convection in salt (sea) water carried out at the Rostov University according to the request of the Applied Physics Institute of the Academy of Sciences. The results obtained and the programs created were given to the Applied Physics Institute, approved by specialists and used afterwards for practical work. Dr. Urintsev has worked during 10 months at the Department of Numerical Methods in Mechanics of Solids of the Problems of Mechanics Institute (Moscow, the Academy of Sciences), where he has actively participated in numerical simulation of nonlinear hydrodynamics processes. The relevant scientific results were presented by Dr. Urintsev as a report under the title "Numerical Solution of Hydrodynamic Stability Problems" (381 pages) and published by the Institute. The FORTRAN package developed by Dr. Urintsev during this time was applied by the contributors of the Laboratory of Numerical Simulation in Hydrodynamics at the Institute. Dr. Urintsev made numerous reports at the Seminar on the Mathematical Problems of Hydrodynamics (under Professor V.I. Yudovich), at the Seminar on the Mechanics of Solids (under Academician I.I.

I have known Alexander Urintsev during 28 years since 1964. From 1975 till 1982 I had a pleasure to carry out joint investigations with him. We have published 9 joint papers. The most significant of them are as follows: G.S. Markman, A.L. Urintsev, About the Influence of High Frequency Vibrations on the Appearance of Secondary Convection Modes. - Izvestiya Akademii Nauk SSSR (News of the USSR Academy of Sciences), Mekhanika zhidkosti i gaza (Fluid and Gas Mechanics), 1976, No. 2, pp. 90-96 (in Russian).

During this whole timespan Dr. Urintsev kept high creative activity and demonstrated high competence in mathematical physics, excellent knowledge of numerical methods and high professional level of programming. I would like also to mention his ability to cooperate in planning and realization of scientific projects, including the creation of original computer codes of rather large extent. He creates programs that function in such operating environments as VAX/VMS, VM/CMS, MS-DOS. He is an expert in such programming languages as FORTRAN 77, C, Lisp, widely uses computer graphics, such scientific subroutine libraries as CERN Program Library, NAG FORTRAN Library, CPC Program Library, IBM SSP and a lot of others. During recent years he has mastered the computer system TEX to prepare scientific papers. All these habits successfully allow him to create his own effective computer codes for different applications. Such problems as hydrodynamic stability, convection, self-organization in nonlinear dynamical systems, appearance of solitons, calculation of motion of charged particles in transportation systems, analysis and projecting of nonlinear magnetic optics systems, are investigated in his articles. The relevant mathematical content consists of analytical and numerical investigation of nonlinear differential equations describing the researched phenomena. Dr. Urintsev uses successfully computer algebra systems such as Mathematica and REDUCE whose wide application is very perspective. He studied the Maple package. A great erudition permits him to work effectively at any stage of research including the mathematical formulation of the problem, its investigation by means of computer and final analysis. The scientific results obtained by Dr. Urintsev are regularly published and well-known to the specialists. He is the author of some 40 scientific papers, many of which published in magazines of the Academy of Sciences and later translated into English. Dr. Urintsev is quite experienced in teaching. During 11 years he worked as an Associate Professor at the Chair of Computational Mathematics and at the Chair of Functions and Functional Analysis Theory of the Mechanical- Mathematical Department of the Rostov State University. He lectured on programming, numerical methods, probability theory, supervised the diploma thesis papers and research work of graduates. I would like to mention that Dr. Urintsev is not only a recognized expert in his field but he is also a charming and reliable person for colleagues and students. As a participant of the collaboration he is known for his ample working capacity, thoroughness and persistence in developing programs and research projects.

I can't help you but I will forward your message to many other people that work in better and greater universities here in Brazil. My university is small; I think you wouldn't have interesting work to do here in Joao Pessoa anyway. Last year I heard something about this: "Some universities in Rio de Janeiro (more than 8 millions inhabitants) and in Sao Paulo (more than 12 millions inhabitants) are interested in russian researchers." I am not sure, but I heard that some russians are working in Rio de Janeiro receiving 2000 dollars (???) a month. Our medium salary is about 1000 dollars. We have a Bitnet discussion list called SBM-L (e-mail: SBM-L @ UFRJ) where we can contact almost all brazilian mathematicians. I sent your message to SBM-L. Many people in Rio de Janeiro and Sao Paulo will read it next week. We can live peacefully and easyly in Brazil. But we have too many and too big problems. We have an inflation rate of 30 % a month. Some of the best Brazilian researchers are going to live in USA and Western Europe. Congratulations for your Curriculum Vitae. Sincerely, Lenimar Nunes P. S. I am sorry for my poor English. ============================================================================= Received: from jinr.dubna.su by jimex (4.1/SMI-4.1) id AA03688; Thu, 12 Aug 93 13:42:58-030 Received: by jinr.dubna.su; Thu, 12 Aug 93 13:48:22 GMT Received: by jinr.dubna.su; Thu, 12 Aug 93 13:48:19 GMT Received: by SE.jinr.dubna.su (4.1/SMI-4.1) id AA14402; Thu, 12 Aug 93 13:47:55 MSK Date: Thu, 12 Aug 1993 13:44:07 +0000 From: Alexander Urintsev <urintsev@se.jinr.dubna.su> To: ccendm03@brufpb.bitnet Message-id: <9308120947.AA14402@SE.jinr.dubna.su> Organization: lshe X-Envelope-to: ccendm03@brufpb.bitnet X-Mailer: MAIL2 ( Ver. 2.09.2 from TECHNO ) Content-transfer-encoding: 7BIT X-Protocol: TCP Dear Prof. Lenimar Nunes, Please excuse me for some delay in communication: I was away from my office for several days (was in Moscow).
