For piecewise constant rate functions, the model-checking problem is shown to be reducible to finding the zeros of an exponential polynomial. Using Sturm sequences and Newton's method, we obtain an approximative model-checking algorithm which is linear in the size of the ICTMC, logarithmic in ...
It can be an appropriate model for repairable systems in the context of reliability growth, specifically, test, analyze, and fix (TAAF), where the failure intensity remains constant as long as the system is working and can take discrete jumps at the time of a failure. It can also be ...
It is shown here that the velocity-depth parameters and the sections of approximately constant velocity may be more precisely defined by using an exponential spline to model the data .doi:10.1007/BF02111925D. L. JuppIan C. F. Stewart
piecewise exponentialcompeting risksTo allow more accurate prediction of hospital length of stay (LOS) after serious injury or illness, a multi-state model is proposed, in which transitions from the hospitalized state to three possible outcome states (home, long-term care, or death) are assumed ...

We started with a piecewise constant hazard function, and we got a piecewise exponential survival function. This piecewise exponential survival function is a strictly decreasing function. The inverse function exists, and we have provided an analytical formula for this inversion. If we have an analytic...
TheDiodeblock can represent either a piecewise linear diode, an exponential diode, or a diode with tabulated I-V curve. Use theFidelity levelparameter to select the level of detail in the dynamics model. Piecewise Linear Diode The piecewise linear diode model is the same model as theSimscape...
In this way, the model (1j) is solved with no controls for t≤t0; controls are introduced at time t0. The time t0 is fixed. For consistency, the following bounds apply to u(t): (9b)0≤u(t)≤1,t∈[t0,T]. The piecewise-constant function u(t) is characterized as follows: (10...
