Purpose This work aims to develop a multi-step approach for the unified integration of 3D construction printing (3DCP) and building information modeling (BIM), allowing users easily automatically outline instructions buildings starting from BIM model ensuring wide spread this new technology in Civil Engineering sector. Design/methodology/approach The proposed methodology exploits Revit BIM, using Dynamo as programming interface generating G-code. Findings paper demonstrates how can extract...
This Letter presents a simple temperature-insensitive optical tilt sensor based on single eccentric-core fiber Bragg grating (ECFBG). By partly inserting an ECFBG into ceramic ferrule, the reflection spectrum of splits two peaks as result applied angle. The magnitude and direction inclination in one dimension can be determined by monitoring wavelength separation between both peaks, which is inherently insensitive to temperature. proposed has good linear response within wide dynamic range...
The structural health monitoring (SHM) of existing buildings, structures, and infrastructures has become increasingly important in recent years, while the interest scientific community is focused on use new high-performance technologies. Fiber optic sensors have particularly attractive, thanks to their potential for strain smart structures. performance this technology depends a large extent bonding technique used its manufacture. Although related literature identified correlation between...
The present paper assesses the performance and characteristics of fiber Bragg grating sensors, with a special interest in their applications hydraulic machinery systems. hydropower industry is turning to this technology high expectations obtaining quality data validate calibrate numerical models that could be used as digital twins key assets, further strengthening sector’s relevant position within 4.0. Prior any validation, sensors’ ability perform well underwater for long periods time...
Shape sensing has become an area of great interest for many medical applications, such as epidural administration, colonoscopy, biopsies, and cardiac procedures, where real-time data a dynamic object is required visual contact absent. Fiber Optic Sensors (FOSS) consist optical multi-fiber cables or Multicore Fibers (MCF) with embedded strain sensors, which can reconstruct the sensor shape from its multidimensional bending. Regrettably, accuracy three-dimensional remarkably restricted because...
Fiber optic shape sensing is innovative technology, which enables distributed structural health monitoring, providing real-time feedback on and position, based smart sensors arrays, consists of optical fiber bundles or multicore fibers with embedded strain sensors. This paper describes a numerical analysis carried out to identify the effects uncertainty in measurement core position accuracy sensors, taking into consideration one most utilized geometry for applications, seven-core Multicore...
A temperature-insensitive 2-D inclinometer by incorporating two fiber Bragg gratings (FBGs) with a homogeneous pendulum transducer is proposed and experimentally demonstrated. The FBGs are located in orthogonal planes of the only half each FBG glued on surface columnar rod. Due to strain difference between glued- non-glued part FBG, reflection spectrum splits into peaks. direction magnitude inclination can be readily determined measuring wavelength separations split peak FBGs, whilst...
