Examples of Dynamical Systems
This course is devoted to the study of systems of ordinary differential equations (ODEs), in terms of analytical and numerical solution techniques, and also acquiring insight into the qualitative behavior of solutions. We begin our study of a general system of n ODEs of the form y′ = F(t,y), where y(t) : R→ Rn and F : Rn+1 → Rn, with some examples that illustrate very different types of qualita...
متن کاملMULTICRITERION SYNTHESIS OF INTELLIGENT CONTROL SYSTEMS OF GENERATING UNIT OF NUCLEAR POWER STATION
The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...
متن کاملThe effect of earth magnetic field on the function of nuclear medicine imaging systems (SPECT)
Background: The nuclear medicine systems are very sensitive to the variation of the magnetic field. Photomultiplier tubes amplify low energy light signal and change it into electrical current. Low magnetic field can produce some variations in uniformity and special resolution of SPECT systems. In this study, we tried to evaluate the effects of magnetic field on the function of nuclear medic...
متن کاملExamples of Early Nonconventional Technical Information Systems
Chemists have a long-standing appreciation for the value of recorded information. Many of the early efforts to improve information-processing techniques were centered on chemical information problems. The preeminence of Chemical Abstracts as a secondary publication service was well established, but the control and effective use of other information resources were objects of much effort and inte...
متن کاملSome Examples of Quantized Linear Hamiltonian Systems
For linear Hamiltonian systems, the reconstruction of the Poisson bracket from a given energy function and an Hamiltonian flow leads to simple quantization rules. They can also be used in the infinite dimensional case. From this point of view, we consider the examples of oscillators, free electro-magnetic fields and vibrating strings.
