Growth of Ru- and RuO2-composite (ROC) nanodots on atomic-layer-deposited Al2O3 film has been studied for the first time using ion-beam sputtering followed by post-deposition annealing (PDA). X-ray photoelectron spectroscopy analyses reveal that RuO2 and R ...
A new method of evaluating the characteristics of postural transition (PT) and their correlation with falling risk in elderly people is described. The time of sit-to-stand and stand-to-sit transitions and their duration were measured using a miniature gyro ...
This paper presents a refined approach to obtain the parameters of synchronous machine equivalent circuits from standstill DC decay tests. A dedicated program for the time- constants and reactances identification was developed and applied for both d- and q ...
A sensor for sensing cryogenic temperatures, which includes an optical fibre(2) and a Brillouin spectral analyser (8) for measuring one or more temperature dependent Brillouin scattering parameters. Once the parameters are measured, they are used to determ ...
BACKGROUND: A theoretical model and an experimental setup were specifically designed to identify and determine the delay of the cortical bone response (restricted to mineralization and demineralization) to a stress change. METHODS: The in vivo experiment c ...
The present invention relates to a system and a method for monitoring body movement, in particular but not exclusively for evaluating the falling risk and/or for monitoring sitting, standing, lying, walking and running periods. The system is characterized ...
Existing content-based publish/subscribe systems are designed assuming that all matching publications are equally relevant to a subscription. As we cannot know in advance the distribution of publication content, the following two unwanted situations are hi ...
In this paper, a micromachined silicon straight tube is tested as a fluid density sensor. In comparison with other density measurement techniques, the use of micromachined tubes require small sample volumes and allows continuous monitoring of the fluid den ...
A functional integration approach – whose main ingredient is the Hubbard-Stratonovich transformation – for the quantum nonrelativistic many-fermion problem is investigated. With this method, the ground state energy correponds to a systematic expansion in p ...
Two different approaches for ultra flat image acquisition sensors on the basis of artificial compound eyes are examined. In apposition optics the image reconstruction is based on moiré- or static sampling while the superposition eye approach produces an ov ...
