Delayed renewal process and delayed renewal reward process are introduced in the framework of uncertainty theory and their uncertainty distributions are provided. Furthermore, delayed renewal theorem on the limit value of the expected renewal rate of the process and delayed renewal reward theorem on the limit value of the long-run expected reward per unit time are presented. At last, some examp...

Urban regeneration and renewal is one of the urban development subjects that have undergone substantial changes in last decades in its approaches and also management process. Despite these global changes, policy making in this field of urban development have been delayed in Iran. In the last three decades, the spread of distressed urban areas in Tehran and their vulnerability against earthquake...

Renewal processes are generalizations of the Poisson process on the real line whose intervals are drawn i.i.d. from some distribution. Modulated renewal processes allow these interevent distributions to vary with time, allowing the introduction of nonstationarity. In this work, we take a nonparametric Bayesian approach, modelling this nonstationarity with a Gaussian process. Our approach is bas...

In renewal processes, fuzziness and randomness often coexist intrinsically. Based on the random fuzzy theory, a delayed renewal process with random fuzzy interarrival times is proposed in this paper. Relations between the renewal number and interarrival times in such a process are investigated, and useful theorems such as the elementary renewal theorem, Blackwell renewal theorem and Smith key r...

he Brazilian Journal of Cardiovascular Surgery (BJCVS) closes the year 2012 with many achievements, a result of hard work of the Editorial Board, the Board of the Brazilian Society of Cardiovascular Surgery and reviewers, who always are fundamental to the scientific level of our journal is growing. An example is the number of citations, always growing, reflecting the Impact Factor (IF), which r...

(1) Sn = S0 + n ∑ i=1 Xi When S0 = 0 the renewal process is an ordinary renewal process; when S0 is a nonnegative random variable the renewal process is a delayed renewal process. In either case, the individual terms Sn of this sequence are called renewals, or sometimes occurrences. With each renewal process is associated a renewal counting process N (t ) that tracks the total number of renewal...

deteriorated urban textures are areas of a city isolated from developmental life cycle. they have turned into the focus of problems and inefficiencies. the evaluation of renewal actions claims to promote residents’ satisfaction in some cases. at the same time of improving objective and economic quality of life, there are claims regarding the lack of any improvements in their subjective quality ...
