The aim of this paper is to investigate properties of the local cohomology of rings of mixed characteristic that are analogous to Segre products of rings de ned over a eld. The main question is whether the local cohomology can be almost killed in a nite extension (we de ne what this means below). There are two reasons for considering this type of ring. First, there are special properties of the...

In this note we construct a class of new splines related to a Blaschke product. They emerge naturally when studying the filter functions of a class of linear time-invariant systems which are related to the boundary values of a Blaschke product for the purpose of sampling non-bandlimited signals using nonlinear Fourier atoms. The new splines generalize the well-known symmetric B-splines. We esta...

at early stages of new product development, the effort tooptimize is low and effects on the whole innovation process are high.therefore, a deeper understanding of fuzzy front end and its successcan help firms to be more successful in developing new products. wepresented and tested a conceptual model of relationships among keyvariable sre lated to the fuzzy front end,execution phase of new produ...

The coordination of complex process structures is a fundamental task for enterprises, such as in the automotive industry. Usually, such process structures consist of several (sub-)processes whose execution must be coordinated and synchronized. Effecting this manually is both ineffective and error-prone. However, we can benefit from the fact that these processes are correlated with product struc...

What are the effects of forced exposure to the brand website on perceived brand personality? An experiment with random assignment to exposure vs. control (nonexposure) groups for ten websites is analysed. Three covariates are included to test their impact on brand personality after website exposure: product type (utilitarian/ functional vs. auto-expressive), enduring involvement with the produc...

A key problem in the manufacture of highlycustomized products is the synthesis of controllers able to manufacture any instance of a given product type on a given production or assembly line. In this paper, we extend classical AI behavior composition to manufacturing settings. We first introduce a novel solution concept for manufacturing composition, target production processes, that are able to...

Attempts at multipole expansion for hadronic transitions in heavy onium states leads us to analyze the process using operator product expansion. We find two regimes where the process can be controlled using operator product expansion. For these processes, it is shown that . a Callan Symanzik equation exists. Problems pertaining to consistent higher order c1 calculations are pointed out. Submitt...

To better understand groups it is often useful to see how a group can be built from smaller groups. For example, given two groups G and H, we can form the direct product G × H. This new group can be studied in terms of the two pieces from which it is built. However, the direct product construction is too special to understand most groups. In other words, most groups are not expressible as the d...

Based on the review data of the Amazon,our research discuss that the effect of language style matching of a review and the whole reviews on perceived customer review helpfulness and the moderating effect of product type and product brand to the relationship between language style matching of a review and the whole reviews and perceived customer review helpfulness. Our study found:For experience...
