SHIGAEV Vladlen Nikolaevich 05.02.1935 – 06.03.2024 On March 06, 2024, Vladlen Nikolaevich Shigaev, a former employee of the M.G.Meshcheryakov Laboratory of Information Technologies, Candidate of Physical and Mathematical Sciences, passed away. Shigaev V.N. was born on February 5, 1935 in the city of Rzhev, Tver region. Almost 60 years of V.N. Shigaev's life were inextricably linked with JINR, where he began working in 1963 after graduating from Lomonosov Moscow State University. From the first days of his work, he was engaged in solving the problem of automating a physical experiment. He made the largest contribution to the creation of a unique mathematical software for the HPD scanning automaton, which formed the basis for his PhD thesis, which was successfully defended in 1979. Shigaev V.N.'s further work was related to the use of artificial neural network (ANN) methodology in calorimetry problems in particle physics experiments. In particular, as part of the STV2004 test experiment, V.N.Shigaev developed an INS procedure for the reconstruction of energy losses, which became an integral part of a new method - a hybrid scheme for the reconstruction of pion energy, created jointly with the physicists of the nuclear power plant for the ATLAS experiment. During his time at the Institute, Vladlen Nikolaevich has established himself as a highly qualified specialist. He is the author of more than 80 publications. V.N. Shigaev's work style was characterized by a responsible approach to business, deep professional study of the problems to be solved, and the ability to achieve high results in solving complex research tasks in the field of automation of physical experiments and analysis of experimental data. In 2012, he was awarded the departmental distinction in the work "Veteran of nuclear energy and Industry". Tactful and friendly attitude to people, responsiveness and modesty earned Shigaev V.N. the respect of colleagues at work. The bright memory of him will remain in the hearts of those who knew him, worked and communicated with him. The staff of the M.G.Meshcheryakov Laboratory of Information Technologies Obituary
