In this paper, we describe a velocity interferometer system based entirely on single-mode fiber optics. This paper includes a description of principles used in developing the single-mode velocity interferometry system (SMV). The SMV design is based on polarization-insensitive components. Polarization adjusters are included to eliminate the effects of residual birefringence and polarization depe...

We report a novel "single trench fiber" design for mode area scaling of the fundamental mode while offering effective single mode operation for a compact fiber laser device. This fiber design allows very high suppression of the higher order modes by offering high loss and power delocalization. It has the advantages of low cost and easy fabrication thanks to all solid fiber design, cylindrical s...

Abstract Employment of natural fiber for the filament fused deposition modeling (FDM) can be found in numerous studies from different areas. However, presence such as kenaf polymer could cause mechanical properties degradation with regard to loading owing low compatibility between and matrix. Therefore, this study aims three-dimensional (3D)-printed structures composites specimens varying volum...

For the structural application of high-performance Steel Fiber Reinforced Expanded-shale Lightweight Concrete (SFRELC), a reliable bond ribbed steel bar should be ensured. In this paper, an experimental study was carried out on properties embedded in SFRELC by direct pull-out test. The produced with strength grade 35 MPa and volume fraction fiber as 0%, 0.8%, 1.2%, 1.6% 2.0%, respectively. Fift...

We demonstrate nearly distortionless 2.5-km fiber transmission of sub-500-fs pulses, using a combination of standard single-mode fiber, dispersion-compensating fiber, and a programmable pulse shaper for simultaneous quadratic and cubic dispersion compensation. The dispersion-compensating fiber corrects the bulk of the quadratic and the cubic phases for the single-mode fiber, and the fiber-pigta...

Plant and animal fibers are getting recognition from researchers academicians as a potential reinforcement for polymer composites due to their ecofriendly nature sustainability. In the present study, fabrication has been carried out on Jute Vetiver fiber reinforced Epoxy using hand lay-up technique with varying mass of in epoxy matrix modifier graphite which fixed by weight. The mechanical (ten...

This paper explores the broad issues of why the meaningful use of ICT to engage in deep learning has not been widespread in K-12 schools. We argue a critical reason is the lack of sustainability in the implementation of ICT-enabled pedagogies in schools, arising from a failure to understand the conditions for systemic innovations. We describe the key issues related to sustainability from litera...
