Due to higher ecological awareness and more stringent environmental laws the necessity of lowering the energy consumption of manufacturing plants rises. Therefore the possibility to optimize a planned production hall becomes more and more important. The research project INFO, a project of the Vienna University of Technology in cooperation with industry partners and supported by the FFG, the Aus...

We investigate the relation between two quantitative measures characterizing short term memory in input driven dynamical systems, namely the short term memory capacity (MC) [3] and the Fisher memory curve (FMC) [2]. We show that even though MC and FMC map the memory structure of the system under investigation from two quite different perspectives, for linear input driven dynamical systems they ...

Arithmetic Kleinian groups are arithmetic lattices in PSL2(C). We present an algorithm that, given such a group Γ, returns a fundamental domain and a finite presentation for Γ with a computable isomorphism.

Disk galaxies in a cluster of galaxies are moving in hot gas filling the cluster. Generally, they are moving at transonic or supersonic velocities. If ram-pressure stripping is insufficient to destroy the gas disk, the galaxies should be affected by the wind of the surrounding hot gas similar to an airfoil. In this paper, I consider whether the aerodynamic interaction can be strong enough to fo...

Parental scaffolding is an important mechanism utilized by infants during their development. Infants, for example, pay stronger attention to the features of objects highlighted by parents and learn the way of manipulating an object while being supported by parents. Parents are known to make modifications in infant-directed actions, i.e. use “motionese”. Motionese is characterized by higher rang...

It is discussed that many researches relevant to the media communication issue user's anonymity widely. However it tends to be unremarked that the physical interaction by the participants who have uncertain attribute symbolized anonymity. This paper focuses the indirect interaction by participants. And we examine that participants recognize existence of the others through the indirect interacti...

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 article the authors review the early history of gauge theory, from Einstein’s theory of gravitation to the appearance of non-abelian gauge theories in the fifties. The authors also review the early history of di...

financial fines are regarded as a powerful implement in the hand of competition authorities which apply in the way of ceasing anticompetitive practices and hindering undertakings from entering into monopolization activities.  having regarded the nature and main function of this sanction, this paper in comparative study is going to clarify executive domain and primary stages of fine determining ...
