New product development (NPD) projects present distinct organizational challenges in terms of their execution: they require specialized competencies, which prompt cross-functional collaboration. Collaboration implies significant interdependencies between the functions, including both, organizational factors (i.e. cross-functional coordination), and those arising from the problem structure (i.e....

Vector cross product structures on manifolds include symplectic, volume, G2and Spin (7)-structures. We show that their knot spaces have natural symplectic structures, and we relate instantons and branes in these manifolds with holomorphic disks and Lagrangian submanifolds in their knot spaces. For the complex case, the holomorphic volume form on a Calabi-Yau manifold de…nes a complex vector cro...

In this paper we present key elements of a peer to peer (P2P) based software architecture for integrated and collaborative product engineering. We argue that distributed and cross-enterprise product lifecycle management can benefit from the availability of decentrally managed product model repositories.We present the overall system architecture of a platform called Peer-to-Peer Product Collabor...

/RESUME In this paper we present comparative evidence from OECD countries concerning the impact of product and labour market regulations on innovation. While product and labour market policies usually aim at objectives other than innovation, they may have important consequences for the profitability of firms' innovative strategies. Our regression analysis provides some crosscountry evidence tha...

This paper explains a novel cross-functional evaluation concept for product portfolio complexity management. In a holistic approach it combines and connects four main evaluation dimensions which are integrated into a complexity index model. The validation of the concept will be explained along an industry project within a manufacturing company.

The paper presents a deductive framework for proving program equivalence and its application to automatic verification of transformations performed by optimizing compilers. To leverage existing program analysis techniques, we reduce the equivalence checking problem to analysis of one system a cross-product of the two input programs. We show how the approach can be effectively used for checking ...

This is an introduction to work on the generalisation to quantum groups of Mackey’s approach to quantisation on homogeneous spaces. We recall the bicrossproduct models of the author, which generalise the quantum double. We describe the general extension theory of Hopf algebras and the nonAbelian cohomology spaces H(H,A) which classify them. They form a new kind of topological quantum number in ...

Sentiment analysis in context of product reviews involves automatically classifying whether users have expressed positive or negative opinions regarding a product. In this paper we define the novel problem of cross-product sentiment analysis, which involves predicting the sentiment polarity of a new product’s reviews using training data available for a different set of products. Our work has hi...

Domain-specific modelling has proved its worth for improving development speed and dependability of applications. By raising the level of abstraction away from the code and towards the structure and behaviour of an application, it also offers good possibilities for generating the same application from the same models, but for a wide variety of client platforms. This paper examines one example o...

A cross-product statistic is used to demonstrate that spatial interaction models are a special case of a general model of spatial autocorrelation. A series of traditional measures of spatial autocorrelation is shown to have a cross-product form. Several interaction models are shown to have a similar form. A general spatial statistic is developed which indicates that the relationship between the...
