Solvability of a multi-point boundary value problem of Neumann type
Let f:[0,1]×?2?? be a function satisfying Carathéodory's conditions and e(t)?L1[0,1]. Let ?i?(0,1),ai??,i=1,2,…,m?2,0<?1<?2<?<?m?2<1 be given. This paper is concerned with the problem of existence of a solution for the ...
Existence theorems for a second order m-point boundary value problem at resonance
Let f [0, I] R R be function satisfying Caratheodory’s conditions and e(t) L[0, 1]. Let r/( (0,1), ’, (0,1), a, >_ 0, 1,2,- ,m- 2, with ,,2 ai 1, 0 < f < f2 < < ,-2 < be given. This paper is concerned with the problem ...
Detection of Mechanical Abnormalities in Induction Motors by Electric Measurements
The paper gives an overview of the issues and means of detection of mechanical abnormalities in induction motors by electric measurements. If undetected and untreated, the worn or damaged bearings, rotor imbalance and ...
Impulse Control in Kalman-Like Filtering Problems
This paper develops the impulse control approach to the observation process in Kalman-like filtering problems, which is based on impulsive modeling of the transition matrix in an observation equation. The impulse control ...
Emergency Control of Unstable Behavior of Nonlinear Systems Induced by Fault
This paper presents the emergency control approach intended to urgently return to the stability basin the system states affected by abrupt changes in certain system coefficients on a short time interval. Because of its ...
