In this paper we investigate the asymptotic properties of the test statistics for detecting change-points in the mean of a set of multivariate long-range dependent observations. The limit theorems of weighted test statistics and weighted Lp-functionals of tests are developed. The limiting...

Mercury (Hg) is a pervasive environmental pollutant and poses serious health concerns as inorganic Hg(II) is converted to methylmercury (MeHg), a neurotoxin, which bioaccumulates in the food webs. Phytoplankton, representing the base of aquatic food webs, can take up Hg(II) and influence MeHg...

In this paper we propose two test statistics for testing serial correlation in semiparametric time series model that could allow lagged dependent variables as explanatory variables .

There have been periodical studies on key IS management issues facing the IT industry in North America; however, an empirical investigation on key IS management issues in developing countries has been largely ad hoc and inadequate. This paper identifies and analyzes important issues faced by CIOs...

Consider n i.i.d. random vectors on R2, with unknown, common distribution function F.Under a sharpening of the extreme value condition on F, we derive a weighted approximation of the corresponding tail copula process.Then we construct a test to check whether the extreme value condition holds by...

The main objective of the work is to develop numerical method for improving design/simulation tools and answering to specific questions related with heat and mass transfer inside a pressurized volumetric receiver (PVR), providing fundamental basis to design new receivers for the DAHAN project...
