The Exact Solution of Min-Time Optimal Control Problem in Constrained LTI Systems: A State Transition Matrix Approach

In this paper, the min-time optimal control problem is mainly investigated in the linear time invariant (LTI) continuous-time control system with a constrained input. A high order dynamical LTI system is firstly considered for this purpose. Then the Pontryagin principle and some necessary optimality conditions have been simultaneously used to solve the optimal control problem. These optimality ...

A Game Theoretic Approach for Sustainable Power Systems Planning in Transition

Intensified industrialization in developing countries has recently resulted in huge electric power demand growth; however, electricity generation in these countries is still heavily reliant on inefficient and traditional non-renewable technologies. In this paper, we develop an integrated game-theoretic model for effective power systems planning thorough balancing between supply and demand for e...

Generating Discrete Trace Transition System of a Polyhe-dral Invariant Hybrid Automaton

Supervisory control and fault diagnosis of hybrid systems need to have complete information about the discrete states transitions of the underling system. From this point of view, the hybrid system should be abstracted to a Discrete Trace Transition System (DTTS) and represented by a discrete mode transition graph. In this paper an effective method is proposed for generating discrete mode trans...

دگرگونی سیمای سلامت در ایران

Background and objectives: Data on transitions in health status are among the most important types of information used for promotion of health and social development. Health transition comprises two elements: demographic and epidemiologic transition. This paper depicts the health transition in I.R. Iran over the last few decades. Methods: We used demographic data gathered over the last 45 ye...

Current Status of Long-term Care in Taiwan: Transition of Long-term Care Plan From 1.0 to 2.0

Predictors of Transition in Different Stages of Smoking: A Longitudinal Study

AbstractBackground: We investigated longitudinally the prevalence of smoking according to three stages of smoking (never smoking, experimenting the smoking, and regular smoking), the rates of transition from one stage to another one, and determinant predictors of transition through these stages of smoking.Methods: Of all 10th grade students in Tabriz, 1785 students were randomly selected and as...
