An environment to support the modeling, analysis, simulation, and development of state transition models, SMOOCHES (State Machines for Object-Oriented Concurrent Hierarchical Engineering Specifications), is presented. SMOOCHES allows the hierarchical construction, analysis, and simulation of state transition models in an object-oriented distributed environment. Statecharts (see Harel, 1987c), a...

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...

thermal rearrangement of 7,7-dichloro-[a,c]-dibenzo-[4,1,0]-bicycloheptane (1) to 5,6-dichloro-5hdibenzo-[a,c]-cycloheptene (2) was studied in the solid phase and in solvents with different polarities. thefirst-order constants at various temperatures for the rearrangement process were evaluated from theabsorption time data. the activation parameters for this rearrangement were obtained from the...

qp_rules.m Calculates for a hydrogen atom, the transition rate and lifetime for a transition from an initial state (n1 l1 ml1) to the final state (n2 l2 ml2). The azimuthal wavefunction is given by an analytical expression, the angular wavefunction is found using the Matlab command legendre and the radial wavefunction is solved by the Matrix Method using the function qp_fh.m. Integrations use t...

A state i is said to be transient if fii < 1; and it is said to be persistent if fii = 1. Denote by q = (q 1, q t 2, . . . , q t n) the state probability vector (the distribution of the chain at time t), to be a row vector whose i-th component is the probability that the Markov chain is in state i at time t. A distribution π is a stationary distribution for a Markov chain with transition matrix...

1 This paper discusses an architecture designed to provide support for the development of state transition models for an object-oriented distributed environment. The state transition models can be constructed and specified hierachically as well as derived into new classes of objects through the use of inheritance. A new concept called “exit-safe states” is introduced to assist in the specificat...

background: human error is the most important cause of occupational and non-occupational accidents. because, it seems necessary to identify, predict and analyze human errors, and also offer appropriate control strategies to reduce errors which cause adverse consequences, the present study was carried out with the aim of identifying human errors while operating meat grinder and offer suggestions...

The transition operator that describes the time evolution of the state probability distribution for continuousstate linear systems is given by an integral operator. A state-discretization approach is proposed, which consists of a finite rank approximation of this integral operator. As a result of the state-discretization procedure, a Markov chain is obtained, in which case the transition operat...

In this paper, we study Markov chains with innnite state block-structured transition matrix with repeated rows and rational structure. We provide an algorithmic approach to nd the stationary probability distribution based on the concepts of linear systems theory. These chains include well-known structured Markov chains such as canonical and non-canonical M/G/1 and G/M/1. We provide a truncation...
