Metalinguistic, shmetalinguistic: the phonology of shm-reduplication

[Clinical study of pediatric kidney transplantation at Kansai].

BACKGROUND The clinical study of pediatric kidney transplantation in Kansai area is reported in this paper. METHODS Seventy six children, 0-15 years old, received renal transplants at 8 transplant centers of Kansai area up to December, 1993. Clinical study was carried out about the etiology of renal failure causes, the graft survival and the complications. RESULTS End-stage renal failure wa...

Power-efficient wireless sensor reachback for SHM

Wireless sensor networks have recently received great attention from the scientic community, because they hold the key to revolutionize many aspects of our economy and life. On the other hand, the design, implementation and operation of a wireless sensor network in a SHM system requires the synergy of many disciplines, including civil engineering, signal processing, networking, etc. The process...

Damage quantification and localization algorithms for indirect SHM of bridges

This paper presents algorithms for diagnosing the severity and location of damage in a laboratory bridge model. We use signal processing and machine learning approaches to analyze the vibration responses collected both directly from the bridge model and indirectly from a vehicle passing over the model. Features are selected using principal component analysis (PCA), and a regression is performed...

SHM of Floating Offshore Wind Turbines— Challenges and First Solutions

The paper presents an integrated SHM-system for floater, moorings, tower, nacelle and rotor blades. Its core is based on a multivariate SHM-system for rotor blades with three different measuring techniques accompanied by appropriate signal processing approaches:  Acoustic Emission (AE) is used for identification of relative small damages at the whole blade, e.g. bursts of fibres, cracks of bon...
