This paper proposes a novel scheme of continuous time assessment of user-level QoS and its continuous time mapping in audio–video transmission over IP networks. In the user–level QoS assessment, we time–continuously utilize the method of successive categories, which is one of the psychometric methods. We also adopt multiple regression analysis as the continuos time QoS mapping. By experiment, w...

In recent years a new evolutionary algorithm for optimization in continuos spaces called Differential Evolution (DE) has developed. DE turns out to need only few evaluation steps to minimize a function. This makes it an interesting candidate for problem domains with high computational costs as for instance in the automatic generation of programs. In this paper a DE-based tree discovering algori...

We are introducing a system for Electrical Impedance Spectroscopy (EIS) measurements for future use in Neurological Intensive Care Unit (NICU) settings. The system consists mostly of commercially available components and the software was developed in Labview (National Instruments). The system is based on the principle that acute hemorrhagic stroke may produce detectable changes in the impedance...

Theories on R&D organisation draw on globalisation literature as well as on communication theories. This mixed discourse is a problem, since mixing levels of logic sometimes cause faulty conclusions. How is this double logic handled in organisations, and what is the effect on R&D organisation? This study investigates R&D activities in multinational companies with several production sites and ma...
