The experimental investigations of the delamination factor of glass fiber reinforced plastic at different cutting parameters are reported in this study. This paper has involved the determination of different factors affecting the hole quality and cause of delamination in a glass fiber reinforced plastic. The various process parameters like different twist drill bits of different materails, diff...

Rotation vector algorithm regarded as a classical and conventional attitude algorithm is widely used in strapdown inertial navigation system. This kind of algorithm usually uses incremental angle in calculation processes. However, the output of fiber-optic gyro is angular rate. Integrating angular rate to get incremental angle leads calculation errors. In this paper, a set of improved attitude ...

We present a novel two-dimensional fiber-optic inclinometer with high sensitivity by crisscrossing two etched chirped fiber Bragg gratings (CFBG) arrays. Each array is composed of two symmetrically-arranged CFBGs. By etching away most of the claddings of the CFBGs to expose the evanescent wave, the reflection spectra are highly sensitive to the surrounding index change. When we immerse only par...

due to the existence of fibrous materials such as plastic fragments, the strength anisotropy of municipal solid waste (msw) materials is the main source of differences between their mechanical response in direct shear and triaxial apparatus. as an extension of earlier research on the mechanical behavior of msw using a large traixail apparatus, results presented in shariatmadari et al. [1] and k...

In this study, a scalable fabrication technique for controlling and maintaining the nanoscale orientation of gold nanorods (GNRs) with long-range macroscale order has been achieved through electrospinning. The volume fraction of GNRs with an average aspect ratio of 3.1 is varied from 0.006 to 0.045 in aqueous poly(ethylene oxide) solutions to generate electrospun fibers possessing different GNR...

Melt-blown fibers (dav ∼1 μm) were produced from blends of poly(butylene terephthalate) (PBT) and a partially fluorinated random multiblock copolyester (PFCE) leading to enhanced hydrophobicity and even superhydrophobicity (static water contact angle = 157 ± 3°) of the associated fiber mats. XPS measurements demonstrated quantitatively that the surface fluorine content increased systematically ...

Self-assembled multilayers of lignosulfonates (LS) were built up on both quartz slides and cellulose fibers using a Cu-mediated layer-by-layer (LBL) technique. The growth of LS multilayers on quartz slides was monitored by UV-Vis spectroscopy, and the absorbance at 205 nm as well as at 280 nm was found to linearly increase with the number of layers. The formation of LS multilayers on fibers sur...

We propose and demonstrate a versatile holographic storage system using a single-mode polarizationmaintained PM fiber guided reference beam. By properly allocating the output coupler of the single-mode fiber, the system provides the ability of angular multiplexing recording with no upper limit of the angle tuning range of the reference beam. In addition, this system can easily achieve different...

Recent focused Monte Carlo and experimental studies on steady-state single-fiber reflectance spectroscopy (SfRS) from a biologically relevant scattering medium have revealed that, as the dimensionless reduced scattering of the medium increases, the SfRS intensity increases monotonically until reaching a plateau. The SfRS signal is semi-empirically decomposed to the product of three contributing...

Glaucoma is characterized by a combination of structural changes in the retina and optic nerve head and functional perimetric damage. Examination and documentation of the retinal nerve fiber layer are essential for the diagnosis and monitoring of glaucoma. Spectral domain Optical coherence tomography (OCT) is a high resolution imaging device capable of obtaining reproducible retinal nerve fiber...
