The need for monitoring the condition of large-scale infrastructure systems has motivated a recent interest in novel sensor technologies for structural health monitoring. To provide the structural health monitoring system with data that captures local structural behavior, the measurement of component-level strain is valuable. Although current foil-based strain gauges are capable of measuring st...

OBJECTIVE Several cases of highly elevated serum levels of creatine kinase (CK) after surgical interventions have been described in the literature. A consensus on possible risk factors is still lacking. We therefore studied CK-levels in a large population of patients undergoing neurosurgical interventions and sought to determine possible risk factors. METHODS We retrospectively analyzed 150 e...

Abs tract . After a brief description of the modern instrumentation used in Geodesy for the detection, of the deformations of the crust of the Earth, follow a list of problems and a discussion concerning the needs for the survey of -the physical quantities of in_ terest in geodesy, geology, geophysics and engineering such as the strain invariants, the optimal network of baselines and the ac_ cu...

Tapestries are an important feature of many historic house and museum collections. They are often displayed on walls as originally intended, either hanging from the top edge or attached around all four edges. Textile conservators are experienced in visually assessing textiles for evidence of damage. Condition assessment by visual inspection is now routine (Lennard 2006). However, such visual in...

INTRODUCTION In 2008 the first ever night-time Moto GP Grand Prix was held in Doha following the construction of permanent outdoor lighting, and in doing so establishing the Qatar event as one of the most spectacular on the Moto GP calendar. With an 18-race series visiting 14 countries, four continents and pan-global television coverage, Moto GP is the premier motorcycle racing World Championsh...

recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. in an industrial fermentation of bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. changes in certain plasmid resident properties o...

Distributed fiber optic sensing presents unique features that have no match in conventional sensing techniques. The ability to measure temperatures and strain at thousands of points along a single fiber is particularly interesting for the monitoring of elongated structures such as pipelines, flow lines, oil wells, and coiled tubing. Sensing systems based on Brillouin and Raman scattering are us...
