One of the major developments of twentieth century physics has been the gradual recognition that a common feature of the known fundamental interactions is their gauge structure. In this talk the early history of gauge theory is reviewed, emphasizing especially Weyl’s seminal contributions of 1918 and 1929.

It is widely believed that information and communication technology (ICT) enables organizations to decrease costs and increase capabilities and thus enables to shape interorganizational coordination. This paper describes guidelines with which the impact of ICT on interorganizational coordination structures can be predicted. The framework used consists of three perspectives: interorganizational ...

Resolving the incompleteness of Weil-Petersson metric on Teichmüller spaces by taking metric and geodesic completion results in two distinct spaces, where the Hopf-Rinow theorem is no longer relevant due to the singular behavior of the Weil-Petersson metric. We construct a geodesic completion of the Teichmüller space through the formalism of Coxeter complex with the Teichmüller space as its non...

In spite of its great phenomenological success, current models of scalar field-driven inflation suffer from important unresolved conceptual issues. New fundamental physics will be required to address these questions. String theory is a candidate for a unified quantum theory of all four forces of nature. As will be shown, string theory may lead to a cosmological background quite different from a...

Most insurance companies publish few data on the occurrence and detection of insurance fraud. This stands in contrast to the previous literature on costly state verification, which has shown that it is optimal to commit to an auditing strategy, as the credible announcement of thoroughly auditing claim reports might act as a powerful deterrent. We show that uncertainty about fraud detection can ...

In general, the realization of major principles and dimensions of citizenship, especially with regard to people’s rights, entitlements, and obligations, is largely determined by the nature of the state, which varies depending on its socio-historical context. It is argued in this article that the recent decades have witnessed a fundamental shift in the nature of the state worldwide, based on neo...

We examine whether the cosmologies with varying speed of light (VSL) are compatible with the second law of thermodynamics. We find that the VSL cosmology with varying fundamental constant is severely constrained by the second law of thermodynamics, whereas the bimetric cosmological models are less constrained.

The determination of contact forces between a grasped object andfingers of a robot hand is treated in this research. In the previous research on fingertip grasps, the underlying assumption is generally that the fingers can apply any required force. In cases of enveloping orpower grasps, the latter assumption does not always hold because some components of the contact forces may not be controlla...

During the last decade the agenda of local and global politics is heavily marked by the encounter of two powerful currents, namely democracy and political Islam. On the one hand Islam as a religion itself is facing a cultural dialectic between a modern and an authentic form, producing a synthesis which is only to be criticized again by a new radical antithesis. Within that framework political I...

We present a method to compute the interaction force during an imposed movement. First, we show how to incorporate a kinematic constraint into the equation of motion of a simple but realistic model of the arm. Second, we apply this method to predict the interaction force during an imposed movement of the arm. The results of these simulations are compared to the interaction force recorded when a...
