Acceptance control charts establish control limits based on specification limits for very capable processes where the mean is permitted to vary. This paper deals with designing such charts when a product has two or more correlated characteristics that must all simultaneously conform to specification limits for the product to be acceptable. We extend past work by solving the general correlated m...

This article addresses regularity of optimal transport maps for cost=“squared distance” on Riemannian manifolds that are products of arbitrarily many round spheres with arbitrary sizes and dimensions. Such manifolds are known to be non-negatively cross-curved [KM2]. Under boundedness and non-vanishing assumptions on the transfered source and target densities we show that optimal maps stay away ...

this research was conducted in the west forest of guilan, northern iran. data from various harvesting methods for 20 years were collected. results showed that, productivity rate of round wood, pulp wood and fuel wood has had an upward trend, while rate of traditional products (lumber, sawn wood, charcoal, etc.) has had a downward trend. production cost has been investigated in this research. th...

We examine the distinguishing number of the Cartesian product of an arbitrary number of complete graphs. We show that for u1 ≤ · · · ≤ ud the distinguishing number of the Cartesian product of complete graphs of these sizes is either du d e or du 1/s d e + 1 where s = Πd−1 i=1 ui. In most cases, which of these values it is can be explicitly determined.

Available online 10 May 2015 In marketing literature, traditional innovation diffusion models have been used for measuring newproduct sales growthwithmixed results. This is primarily because suchmodels fail to identify the difference between the diffusion of awareness about a newproduct and the actual adoption by consumers. This aspect is extremely important for manufacturers of high technology...

The combination of ex situ dynamic nuclear polarization (DNP) with nuclear magnetic resonance (NMR) leads to signal-to-noise enhancements of 10(3)-10(4) compared to conventional NMR. Ex situ DNP, however, is ill-suited for collecting the array of transients needed in 2D NMR spectroscopy. Spatially encoded single-scan 2D NMR methods can circumvent this drawback, yet these "ultrafast" experiments...

Advanced glycoxidation end products (AGEs) play an important role in the pathogenesis of neurodegenerations and we studied if AGEs could represent a useful marker in patients with multiple sclerosis (MS). AGE-products were assessed in cerebrospinal fluid (CSF) and serum of 31 patients with MS and 8 controls. We did not find any statistically significant differences in patients with MS and contr...

In this paper, we consider the demand for multiple successive generations of products and develop a population growth model that allows demand transitions across multiple product generations, and takes into consideration the effect of competition. We propose an iterative descent method for obtaining the parameter estimates and the covariance matrix, and show that the method is theoretically sou...
