Multiple structural breaks detection for Interval-Valued Time Series (IVTS) is undoubtedly relevant under practical perspectives and challenging the point of view analysis expert systems. In this respect, financial time series usually show high variability outliers; moreover, they often exhibit property being frequency nature; thus, it naturally advisable to consider them as IVTS type a given u...

Optimization technology is widely applied to maximize economic profit under ecology constrains in environmental management systems. To tackle the inherent uncertainties, inexact optimization methods have been proposed. Interval linear program- ming (ILP) model has drawn increasing scholarly attention. ILP describe uncertainty by one coarse scaled stochastic process. However, often involves mult...

This paper deals with fault diagnosis of timed discrete event systems (TDESs), using a nondeterministic model named labeled time Petri net (LTPN). Thanks to a skillful splitting of time intervals assigned to the LTPN transitions, analyzing diagnosability in such a timed context can be performed using techniques from the untimed context. Moreover, a deterministic structure called augmented state...

Many embedded real-time applications have strict time constraints to perform computations and access I/O devices. However, aspects related to real-time scheduling algorithms may interfere with the execution of jobs reducing the benefit of a task. We assume that the execution of a job has a positive benefit if performed inside an ideal time-interval. Operations performed before or after this ide...

It is a challenging task to reason about a dynamically evolving system with events triggering state transitions and uncertainty about the ordering of events. In previous research, uncertainty of the event ordering is mainly modelled by partial orders over the events. In this paper, we investigate uncertainty of the event ordering modelled by time intervals in which the events may occur. Each ev...

Motivation Despite the potential usefulness, the association analysis of gene expression with interval times of two events has been hampered because the occurrence of events can be censored and the conventional survival analysis is not suitable to handle two censored events. However, the recent advances of multivariate survival analysis considering multiple censored events together provide an u...

OBJECTIVE To test the hypothesis that children with a previous history of concussion have a longer duration of symptoms after a repeat concussion than those without such a history. METHODS Prospective cohort study of consecutive patients 11 to 22 years old presenting to the emergency department of a children's hospital with an acute concussion. The main outcome measure was time to symptom res...

In this paper we consider the asymptotic stability of linear interval time-delay systems on the base of using Lyapunov’s direct method and methods of interval analysis. A sufficient condition of asymptotic stability is obtained using the concept of Lyapunov–Krasovsky functional.
