Hello!

My name is Yury Berengard. In far 1967, having graduated the Moscow automobile-and-road construction institute on the speciality "Hydrodrive and Hydropneumoautomatics ", I have come as young expert to All-Union scientific research institute of building and road construction engineering. To me has carried: I at once have got in a department of mathematical methods of researches and computer facilities and began to work on a joint of my basic specialty and applied mathematics. In parallel with work I continued study and in 1971 have graduated mechanical-and-mathematical faculty of the Moscow University. From 1974 during 16 with superfluous years I with pleasure and hobby was engaged in development of algorithms and programs for the computer-aided analysis and simulation of systems of drives.

As a result universal algorithms and programs of dynamic analysis and static calculation of hydro volumetric and hydro mechanical drives of arbitrary structure have been developed. These programs have found wide application at designing building and road construction machines, with their help various variants of drives and transmissions of mobile machines have been investigated and developed. The saved up material has found reflection in two monographs, various articles, reports and manuals. The thesis for a candidate's degree has been protected (1979) and the thesis for a doctor's degree has been prepared (1989) by me.

The experience received by me would be impossible without participation of my colleagues and teachers, and first of all – Michael M. Gaitsgori and Rafael М. Pasynkov, unfortunately already died. Special gratitude for the constant help and support I wish to express Eugenie Y. Malinovsky and Lev B. Zaretsky rendered on me huge human and professional influence and at whom I very much have learned much.

In 2001 I have started to be engaged in creation of educational sites. First the sites on the elementary mathematics for the senior schoolboys and entrants www.bymath.net (Russian, 2004) and www.bymath.com (English, 2002) which enjoy the big popularity have been made.

Now there has come turn of students and post-graduate students. Two versions of the site on the applied and engineering mathematics www.simumath.net (Russian) and www.simumath.com (English) are offered your attention. The first part «Applied mathematics» contains numerical methods most applied in an engineering practice. In the second part «Engineering mathematics» my works in the field of simulation and computer-aided design of hydraulic and hydro mechanical drives and transmissions have found reflection.
