Sparked by Efron’s seminal paper, the decade of the 1980s was a period of active research on bootstrap methods for independent data— mainly i.i.d. or regression set-ups. By contrast, in the 1990s much research was directed towards resampling dependent data, for example, time series and random fields. Consequently, the availability of valid nonparametric inference procedures based on resampling ...

knowledge of seasonal fluctuations is of great importance for sale management. the aim of this research is to assess the impact of sale season on the log and lumber prices. hence, after evaluation of sale documents in azarood forestry plan, the data of 410 timber sale lots at roadside of four seasons from 1992 to 2008 were extracted and incorporated into a dataset. calculating the average selli...

Giant impacts by comets and asteroids have probably had an important influence on terrestrial biological evolution. We know of around 180 high velocity impact craters on the Earth with ages up to 2400 Myr and diameters up to 300 km. Some studies have identified a periodicity in their age distribution, with periods ranging from 13 to 50 Myr. It has further been claimed that such periods may be c...

In this article, we present the results of an analysis that describes the research centered on Journal Impact Factors (JIFs). The purpose of the analysis is to make a start of studying part of the field of quantitative science studies that relates to the most famous and classic bibliometric indicator around and to see what characteristics apply to the research on JIFs. In this article, we start...

This paper studies a high frequency time series of oil futures trading contracts and the affect that publicly announced macroeconomic information in the form of an Oil Inventory announcement given by the Energy Information Association in the US has upon it. Using the time series sampled at a five-minute frequency, it is the intention to detect any impacts to the price of the contracts after the...

This research addresses a critical issue of service level agreement (SLA) violation handling, i.e., time constraint violation related to service-based systems (SBS). Whenever an SLA violation occurs to a service, it can potentially impact dependent services, leading to unreliable SBS. Therefore, an SLA violation handling support is much required to produce a robust and adaptive SBS. There are s...

The theory of electron impact ionization of oneand two-electron atoms has advanced significantly in the past two years. This paper will summarize the progress that the members of our research center have contributed to.
