Long-Period Fiber Grating Sensor to Determine Fluoride Contamination in Water
Abstract: The spectral response of uniform long period fiber grating is analyzed theoretically considering fluoride contaminated water as its surrounding medium. The response is studied for fluoride concentration variations ranging from 1 to 20 ppm. Our analysis is based on the study of shift in resonance wavelength of the grating with change in effective refractive indices of cladding modes due to change in fluoride ion concentration in water. Results provide insight …

Design and Analysis of Dispersion Flattened Low Loss Photonic Crystal Fiber
Abstract: AbstractThis paper demonstrates the study of triangular lattice hexagonal photonic crystal fiber with GeO2 doped core. The photonic crystal fiber (PCF) studied in this research work has a core doped with 97% molar concentrated GeO2 with seven layers of air-capillaries around the core. The design and analysis of optical characteristics, i.e., dispersion, confinement loss, and effective area have been studied extensively for optimizing the structure for a certain range of …

Enhanced Durability and Performance of Reinforced Concrete Beams through CFRP Wrapping: An Experimental Investigation
Abstract: Globally, maintaining and repairing aging reinforced concrete structures poses a significant challenge for the construction industry. Numerous structures built before modern earthquake-resistant design codes lack adequate seismic resilience. Additionally, evolving service requirements often necessitate strengthening existing structures to handle increased loads. While past research explored the effectiveness of various Fiber Reinforced Polymer (FRP) wrappings under specific conditions, limited studies have comprehensively compared the performance of Carbon Fiber Reinforced Polymer (CFRP) …

Designing, Constructing and Testing a 90 cm Parabolic Satellite Dish Using Fiberglass Material
Abstract: In this paper, we designed and constructed a parabolic satellite dish using fiberglass material for Ku-band reception that would be able to receive stations from any transponder focused on it which may be coded or non-coded stations. To achieve this objective, a parabolic graph was plotted using the geometry calculations of a parabola (i.e., the axis of asymmetry against its directrix). From this calculation and graph, the form-work was obtained …
